Create a diagram of the mold.

Despite the fact that it is drawn in accordance with the national drawing standards, it is also required to combine the factory standards and factory customary drawing methods that are not specified by the country. It is important to make sure that the drawing contains the words "process dimensions" to indicate the dimensions that are guaranteed by the subsequent process. In the event that burr repair is the only mechanical processing that is carried out after molding, then the process drawing will be identical to the part drawing in every respect.

The part number, the name, the material, the material shrinkage, the drawing scale a356 Aluminum Alloy, and other information should be marked. It is common practice to draw the process drawings on top of the drawing of the die-casting mold assembly. For the assembly drawing, you should make an effort to use a ratio of one to one. It is recommended that the following components be included in the die-casting mold assembly drawing:

An integral component of the structure is the die-casting mold.

1. Structural form of pouring system and exhaust system. A method for picking up parts and a surface that is divided. The structure having an appearance, as well as all of the connecting parts, positioning parts, and guide parts. The cavity height a356 Aluminum Alloy dimension is not required, but it should be marked. Additionally, the overall size of the mold should be marked.

2. Organize all of the components by numbering them and finishing the detailed list. Make a note of the technical requirements and the implementation instructions. Drawings for die-casting mold assembly must meet the following technical requirements: Certain die-casting molds have specific performance requirements that must be meeting.

3. Requirements for die-casting mold assembly process. For instance, once the die-casting mold has been assembled, the fitting gap of the parting surface should not be any larger than 0.05 millimeters. It is important to make a note of the parallelism requirements on both the upper and lower sides of the mold. Additionally, it is important to highlight the size that is determined by assembly as well as the requirements for this size. Methods of assembly and disassembly, as well as the utilization of die-casting molds. Anti-oxidation treatment, die-casting mold numbering, engraving, marking, oil sealing, storage, and other requirements are all included in this category. Draw diagrams of every component.

This is the order in which the parts should be drawn from the assembly drawing of the die-casting mold: the inside should come first, followed by the outside, the complex should come first, followed by the simple, and the structural parts should come first.

Requirements for presentation:a proportional drawing is required, and either an increase or a decrease in size is permitted. The views have been carefully selected, accurately projected, and arranged in an appropriate manner.

4. The dimensions have to be unified, centralized, organized, and covered in their entirety. The order in which dimensions are marked is as follows: first, the dimensions of the main parts and the draft angle are marked, then the dimensions that match are marked, and finally, all of the dimensions are marked. You should first mark the dimensions that match on drawings of non-main parts, and then you should precision die casting supplier mark all of the dimensions. The roughness of the surface. The roughness that is used the most frequently should be marked in the upper right corner of the drawing. Additionally, any other roughness symbols should be marked on each surface of the part. in the correct manner must be filled in.

Checking for errors, examining drawings, tracing drawings, and submitting them for publication are all included.

A. The following items are included in the self-proofreading process: the mold and mold parts must be in accordance with the specifications of the plastic part drawings. Parts made of plastic It is important to determine whether the flow of plastic material, shrinkage holes, weld marks, cracks, demoulding slope, and other factors have an impact on the performance, dimensional accuracy, surface quality, and other requirements of plastic parts. Molding apparatus and tools

To determine whether the injection volume, injection pressure, and clamping force are adequate, to determine whether there are any issues with the installation of the mold, the core of the plastic parts, and the demoulding, and to determine whether the nozzle of the injection machine and the mouth sleeve are in correct contact with one another. The structure of the die-casting mold

Whether the parting surface position and finishing accuracy meet the requirements, whether there will be an overflow or not, and whether the plastic parts can be ensured to remain on the side of the mold with the ejection device after the mold has been opened. Whether the method of demoulding is correct, whether the size, position, and quantity of the extension rod and push tube are appropriate, whether the push plate will be stuck by the core, and whether it will cause scratches on the molded parts are all important considerations.

Temperature adjustment for the die-casting mold (number three). The power and quantity of the heater; whether the flow line of the cooling medium is located in an appropriate location, is of an appropriate size, and has an appropriate quantity. How to deal with undercuts in plastic parts and whether or not the mechanism for removing undercuts is appropriate. For example, whether or not the slider and push rod in the core-pulling mechanism of the inclined guide column interfere with each other.

5. Whether the pouring and exhaust systems are situated in the appropriate location and are of the appropriate size. Drafts of the design

1) Whether or not the positioning of each mold part on the assembly drawing is appropriate, whether or not the representation is clear, and whether or not there are any omissionsOn the drawing of the parts, the part number and name, the production quantity, whether the part is made in-house or outsourced, whether it is a standard part or a non-standard part, the processing accuracy of the parts, the correction processing wire rope clips and allowance of the high-precision dimensions of the molded plastic parts, and whether or not the material, heat treatment, surface treatment, and surface finishing degree of the mold parts are clearly marked and described are all important aspects to consider.

2) The size figures should be accurate and there should be no need for any conversions from the manufacturer. Make sure that the view position of all of the drawings of the parts and assembly is correct, that the projection is accurate precision die casting supplier, that the drawing method is in accordance with the national drawing standards, and that there are no dimensions that are missing. Check the performance of the processing.

Consequently, once the processing of the mold has been finished, a trial mold test needs to be carried out in order to examine the various molded components. Is the quality of the product? Following the discovery of the error, the mold wire rope clips will be repaired in order to rectify the situation going forward.

There is a wide variety of defects that can be found in plastic components, and the reasons behind them are also quite complicated. Before the mold is repaired, a comprehensive analysis and study should be carried out based on the actual situation of the adverse phenomena in the plastic parts. Additionally, the causes of the defects in the plastic parts should be discovered, and potential solutions should be suggested. As a general rule, the molding conditions should be altered first. This is due to the fact that modification of the molding conditions is relatively simple. When the problem cannot be resolved by altering the conditions of the molding process, the option of repairing the mold is considered.
