1. Inspection of injection mold drawings

The injection mold debugging must be prepared according to the mold debugging notice issued by the external cooperation department or the production department. The first step is to review the drawings. There are two drawings here, one is the product drawing for mold debugging, and the other is the mold drawing. According to the product drawings, understand the material, geometric size, function and appearance requirements of the product, such as color, spots, impurities, joints, depressions, etc. According to the mold drawing, you can know the equipment selected for mold debugging, whether the technical parameters are consistent with the mold requirements, and whether the tools and accessories are complete. After the drawing is reviewed, it is passed to the next process.

2. Inspection of injection mold equipment

Check the oil circuit, water circuit, circuit, and mechanical moving parts of the equipment used, and maintain the equipment as required; check the technical parameters of the equipment: The diameter of the positioning ring, the size of the nozzle sphere, the nozzle diameter, the minimum mold thickness, the maximum mold thickness, the stroke of the mold transfer, the distance between the tie rods, and the ejection method should be full.

3. Preparation of injection mold materials

Check whether the specifications, models, grades, additives, color masterbatches, etc. of the processed plastic raw materials meet the requirements. For the raw materials with high humidity, drying treatment should be carried out to determine the ratio. In principle, the raw materials should be the raw materials specified in the drawings, because the injection mold is designed according to the physical and mechanical properties of the raw materials. It is also possible to use raw materials with good fluidity, easy and rapid curing, and good thermal stability. The structure of the test mold can truly reflect the distribution of each part of the product, rounded corners, wall thickness, and reinforcing ribs, which can be used as a reference for modifying the injection mold.

4. Inspection of injection molds

Before the injection mold is installed on the injection machine, the mold should be checked according to the mold drawing, so as to find the problem in time and repair the mold. According to the assembly drawing of the injection mold, you can check the overall size of the mold, the size of the positioning ring, the size of the inlet of the main channel, the size of the sphere that matches the nozzle, the inlet and outlet of the cooling water, the height and width of the platen pad, etc. The pouring system and cavity of the injection mold need to be opened for inspection. When the movable mold and the fixed mold of the mold are separated, attention should be paid to the direction marks to avoid mistakes when closing.

5. Inspection of injection mold tools and accessories

The mold test tool is a special tool for mold test personnel. It is packed in a portable tool box and is easy to carry. Each debugger should have one set. Tools related to mold testing are mechanical wrenches, spacers, thermometers for checking mold temperature, gauges for checking mold dimensions, tools for checking products, etc., as well as copper rods, copper sheets and sandpaper commonly used in operation. The inspection of the inserts is very important. The various inserts of the test mold include metal inserts, plastic inserts, rubber inserts, paper product inserts, and stereotypes to ensure that the injection mold products are not deformed after molding. Strict testing is carried out to avoid damage to the mold and cause irreparable losses.
