Abstract

The invention relates to a roller injection mold for a castor. The roller injection mold for the castor comprises a base, a movable mold and a fixed mold, wherein a circular cavity is formed in the intermediate position of the movable mold; a circular boss is arranged in the center of the circular cavity; an injection hole is formed in the center of the circular boss; a positioning hole is formed in the circular boss; a circular cavity and a circular boss which are of the same structures as the fixed mold are arranged in the center of the fixed mold; the base is arranged at the lower end of the fixed mold; an ejector rob is arranged on the base and penetrates into the positioning hole. According to the injection mold disclosed by the invention, the design is simple, the structure is reasonable, the yield is increased, the production precision of the injection mold is high, and the product quality is improved.

Description

A kind of roller injection mould of castor
Technical field
The present invention relates to a kind of injection mould, is a kind of roller injection mould of castor specifically.
Background technology
A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production.The material melted that is heated is injected die cavity by high pressure by concrete finger, after cooling curing, obtains formed products.
And when processing some particular component, just need to design corresponding injection mould, improve the batch production of product, ensure accuracy and the output of product, and existing injection mould Chang Yinwei design is unreasonable, injecting products is when die sinking, and precision can not be guaranteed, and directly affects the Forming Quality of product.
Summary of the invention
The present invention is mainly used in processing the roller of castor, to improve output and the product accuracy of product.
Technical scheme of the present invention is: a kind of roller injection mould of castor, comprise base, dynamic model and cover half, described dynamic model centre position is provided with circular cavity, be provided with round boss in the middle of described circular cavity, be provided with injecting hole in the middle of described round boss, cover half round boss is provided with locating hole, mutually isostructural circular cavity and round boss with cover half is provided with in the middle of described cover half, described cover half lower end is provided with base, and base is provided with push rod, and described push rod interts in described locating hole.
Described round boss upper surface is cambered surface.
Cooling line is respectively equipped with in described dynamic model and cover half.
The invention has the beneficial effects as follows: injection mould of the present invention, has simplicity of design, rational in infrastructure, improves output, and this injection mould production precision is high, improves the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
