Suzhou plastic mold making drawing all parts
The disassembly and drawing sequence of the parts drawing in the Suzhou plastic mold manufacturing assembly drawing is: first inside and then outside, first complicated and then simple, first formed and then structural parts. Drawing requirements: must be drawn to size, and allow to zoom in or out. Projector selection is reasonable, projection is correct, layout is reasonable. In order to make the processing patent number easy to understand and assemble, the drawing must be as consistent as possible with the assembly drawing, and the drawing must be clear. The dimensions shall be uniform, centralized, orderly and complete. Size: main part size and drawing groove size, and then match the size. Re-dimension all dimensions. On the drawings of non-major parts, the assembly dimensions shall be marked first, and then all dimensions shall be marked. Surface

On the drawings of non-major parts, the assembly dimensions shall be marked first, and then all dimensions shall be marked. Surface roughness. In the upper right corner of the drawing, mark the widely used roughness, such as "other 3.2". Other roughness symbols are marked on each surface of the part. Correctly fill in the part name, mold drawing number, material grade, heat treatment and hardness requirements, surface treatment, graphic proportion, free dimension machining accuracy, technical description, etc.
Proofreading, drawing review, drawing tracking and light transmission:
Self-school content includes:
1. Suzhou plastic mold production and its parts and plastic parts drawings
Whether the material, hardness, dimensional accuracy and structure of the mold and mold parts meet the requirements of the plastic parts drawings.
2. Plastic parts
Whether the flow, shrinkage, welding marks, cracks and demoulding grooves of plastic flow materials affect the performance, dimensional accuracy and surface quality of plastic parts. If the pattern design is not enough, whether the process is simple, whether to choose the appropriate shrink molding material.
3. Molding equipment
Whether the injection volume, injection pressure and clamping force are sufficient, whether there is any problem with the molding, coring and demoulding of plastic parts, and whether the contact between the nozzle of the injection machine and the mouth sleeve is correct.
4. Suzhou plastic mold production structure
1) Whether the parting surface position and finishing accuracy meet the requirements, whether there is material overflow, and whether the plastic parts can be guaranteed to stay on the side of the mold with ejector after mold opening.
2) Whether the demoulding method is correct, whether the size, position and quantity of the ejector rod and push rod are appropriate, and whether the push plate will be stuck by the core and scratch the molded part.
3) Suzhou plastic mold production temperature adjustment. The power and quantity of the heater; whether the streamline position, size and quantity of the cooling medium are appropriate.
4) The treatment method of plastic concave, whether the mechanism to remove the concave is appropriate, such as whether the slider and the push rod in the core pulling mechanism of the inclined guide post interfere with each other.
5) Whether the position and size of the pouring and exhaust system are appropriate.
Design Drawings:
1) Whether the placement of Suzhou plastic mold parts on the assembly drawing is appropriate, whether there are clear instructions, and whether there are omissions
2) The part number and name on the part drawing, the manufacturing quantity, whether the part is manufactured internally or purchased, whether it is a standard part or a non-standard part, the matching processing accuracy of the part, the correction processing and allowance of the high-precision size of the injection molded part, and whether the material, heat treatment, surface treatment and surface finish of the mold part are clearly marked and explained.
3) The working dimensions and matching dimensions of the main parts and molded parts. Dimensional figures shall be correct and shall not be converted by the manufacturer.
