Description

Production mould with high-smoothness plastic

Technical Field

The utility model relates to a mould field especially relates to a production mould with high smooth degree plastics.

Background

The main component of the plastic is resin. The resin means a polymer compound which has not been mixed with various additives. The term resin is originally named from lipids secreted by animals and plants. The resin accounts for about 40-100% of the total weight of the plastic. The basic properties of plastics are largely determined by the nature of the resin, but additives also play an important role. Some plastic cushions are relatively smooth and are typically injection molded with an injection mold.

And current injection mold is when using, and some lack the ejecting piece, need increase the amount of labour that the manual work was taken, reduction production efficiency.

In order to solve the problems, the application provides a production mold for plastic with high smoothness.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-2, the mold for producing plastic with high smoothness provided by the present invention comprises a bottom mold 1, wherein guide pillars 2 are fixedly installed at four corners of the bottom mold 1;

a top die 3 is sleeved on the guide pillar 2 in a sliding manner, an ejection piece 4 is arranged on the guide pillar 2 in a sliding manner, the ejection piece 4 is matched with the bottom die 1, and the ejection piece 4 is connected with the top die 3 through a chain 5;

the bottom die 1 is provided with a cooling member 6.

In an alternative embodiment, the ejector 4 includes a frame 41 and a supporting rod 42, the frame 41 is slidably sleeved on the guide post 2, the supporting rod 42 is fixedly installed at a central opening of the frame 41, a groove matched with the supporting rod 42 is formed in the bottom die 1, and when the frame 41 and the supporting rod 42 are away from the bottom die 1 in the vertical direction, the supporting rod 42 supports the plastic pad.

In an alternative embodiment, the cooling element 6 comprises a cooling pipe 61 and a cooling fin 62, the cooling pipe 61 is laid inside the bottom mold 1, and one side of the cooling fin 62 extends into the inside of the bottom mold 1 to assist in cooling by heat dissipation.
