A rigorous attitude is the prerequisite for successful work, and the commissioning of injection mold must be prepared before all work.
Drawing inspection
For injection mold debugging, the external cooperation department or production department must issue a mold debugging notice to start preparation. The first step is to check the drawings, which are in two copies. One is the mold debugging product drawing, and the other is the mold drawing. Understand the material, geometry, function, and appearance requirements of the product according to the product drawings, such as color, spots, impurities, scars, and dents. Injection mold manufacturing
Equipment inspection
Check the technical parameters of the equipment: the diameter of the positioning ring, the size of the nozzle sphere R, the diameter of the nozzle, the minimum mold thickness, the maximum mold thickness, the maximum mold thickness, the maximum mold thickness, the maximum mold thickness, the maximum mold thickness, the mold stroke, the rod spacing, and the top square meet the testing requirements of the part, and prepare for the preparatory work before starting.
The test equipment should be consistent with the machine during production. This is because the technical parameters of the equipment are related to the technical standards of the test product. Temperature fluctuations, pressure changes, idle cycle time, and the stability of mechanical and hydraulic transmissions will affect product quality.
stores reserve
Check the specifications, models, grades, additives, masterbatches, etc. of processing plastic raw materials to meet the humidity requirements of the raw materials, and determine the drying ratio.
In principle, raw materials should be designed according to the regulations for raw materials, as molds are designed based on the physical properties of the raw materials. Injection mold design supplier
Mold inspection
Before installing the mold into the injection molding machine, the maintenance mode should be carried out according to the mold inspection on the mold drawing, and problems should be detected in a timely manner. According to the assembly drawing of the injection mold, you can check the mold size, the size of the positioning ring, the inlet size of the main channel, the ball size R, and the inlet and outlet of the cooling water, as well as the height and width of the pressing plate.
Cooling water pipe or heating line
Open the cooling water pipe or heating line of the mold for inspection. If using hydraulic or motor surfaces, they should also be connected for inspection.
Tools and accessories
The testing tool is a special tool for testers, and the clothing in the portable tool box is easy to carry. Each specialist should be equipped with one set. Tools related to molds are manipulators, pads, inspection of mold thermometers, inspection of the dimensions of mold card equipment, inspection of tools used, and operation of commonly used copper rods, copper, and sandpaper spare parts.
