The design of China Injection Auto Mould is based on the correct design of plastic products. Mold design and manufacturing are closely related to plastic processing. The success or failure of plastic processing depends largely on the effect of mold design and mold manufacturing quality. The structural elements that need to be considered for plastic mold design are:

　　1. The parting surface is the contact surface where the concave mold and the convex mold cooperate with each other when the mold is closed. The selection of its location and form is affected by factors such as product shape and appearance, wall thickness, molding method, post-processing technology, mold type and structure, demolding method and molding machine structure.

　　2, structural parts, that is, sliders, inclined tops, straight top blocks, etc. of complex molds. The design of structural parts is very critical, and it is related to the life of the mold, processing cycle, cost, product quality, etc. Therefore, the design of the core structure of complex molds requires the designer to have a higher comprehensive ability, and the pursuit of simpler, more durable and more economical is as much as possible. Design.

　　 Mould structure design

　　Plastic parts are small in size, low in product accuracy, and require good performance, no cracks, bending resistance, and mass production. This time the mold is designed as a one-mold eight-cavity structure, and the following problems have been solved.

1. The balance of the gating system. Multi-cavity molds should be designed so that all cavities are fed at the same time as much as possible. Due to the increase in the number of cavities, the length of the runner must increase. Before the melt reaches the cavity, the injection pressure And there will be a large loss of heat of the melt. If the shunt design is slightly unreasonable, the plastic parts may have defects, such as the case of one cavity or several cavities filling up, or filling up immediately, but there are such as poor welding or internal organization. Disadvantages such as porosity, if the injection pressure is increased, it is easy to produce flash.
2. The design of the cooling system of Auto Interior Parts Mould ManufacturersThe design principle of this cooling device is to design the cooling device on the basis of not increasing the structure of the mold itself, and to meet the transfer area required for cooling and the mold structure permits, cooling The number of circuits is designed as much as possible, and the aperture of the cooling channel is as large as possible. Cooling water holes are machined on the upper and lower cavity plates and the movable and fixed template. The cooling water holes of the upper cavity plate and the water holes of the fixed template are butted during installation. , And then sealed with a sealing ring, the cooling water hole of the lower cavity plate is connected with the water hole of the movable mold plate, and is also sealed with a sealing ring, and the water holes are arranged on the upper and lower cavity plates and the movable mold plate.
