The Injection Molding Process Of Car Plastic Injection Mould

In addition to the mold itself, it also needs a mold base, a mold base, and a mold core leading to the ejection device of the part. These parts are generally made of universal type. Mold companies need to be bigger and more refined. They must determine product positioning and market positioning according to market demand, technology, capital, equipment, and other conditions. These practices are especially worthy of learning and reference by small mold companies and focus on gradually forming their technical advantages and products. Advantage. Therefore, my country's mold companies must actively strive to learn from the experience of these advanced foreign companies to better develop in the future.

    Mold processing process arrangement, bottom surface processing, processing volume guarantee; casting rough reference alignment, 2D, 3D surface allowance check; 2D, 3D surface roughing, non-installation and non-working plane processing including safety platform surface, buffer installation Before semi-finishing, the side reference surface is aligned to ensure accuracy; semi-finishing 2D and 3D profiles, finishing all kinds of installation work surfaces including limit block installation surface and the contact surface, inlay Block mounting surface, and backside, punch mounting surface, scrap cutter mounting surface and backside, spring mounting surface and contact surface, various stroke limit working surfaces, inclined wedge mounting surface and backside, semi-finished various guide surfaces, Guide hole, leave margin for finishing process reference hole and the height reference surface, and record the data;

    Inspection and review of machining accuracy; fitter inlaying process; before finishing, the datum surface of the process reference hole is aligned, and the insert margin is checked; the finishing profile 2D, 3D, side punching profile and hole position, finishing process reference hole and Height benchmark, finishing guide surface and guide hole; inspection and review of machining accuracy. Die-casting mold is a method of casting liquid die forging, a process completed on a dedicated die-casting die forging machine. Its basic process is: the molten metal is firstly cast into the cavity of the mold at low or high speed. The mold has a movable cavity surface. It is pressurized forged with the cooling process of the molten metal, which eliminates the shrinkage of the blank. Loose defects also make the internal structure of the blank reach broken grains in the forged state. The comprehensive mechanical properties of the blank have been significantly improved.

   Die-casting materials, die-casting machines, and molds are the three major elements of die-casting production, all of which are indispensable. The so-called die-casting process is to organically and comprehensively use these three elements to enable stable, rhythmic, and efficient production of qualified castings with good appearance, internal quality, and dimensions that meet the requirements of the drawing or agreement, or even your quality castings. process.

    During the design process of die-casting car plastic injection mould, the process is analyzed and the process is determined according to the materials used in the product, the shape and accuracy of the product, and other indicators. Determine the position of the product in the mold cavity, analyze and design the parting surface, the overflow system, and the pouring system. Design the core assembly method and fixing method of each activity. Design of core pulling distance and force. The design of the ejector mechanism. Determine the die casting machine, design the mold base and cooling system. Check the relative dimensions of the mold and die-casting machine, and draw the process drawing of the mold and each part. The design is complete.
