Garbage can and injection mold thereof

Abstract

The invention relates to the technical field of plastic processing, in particular to a garbage can and an injection mold thereof. The injection mold comprises a base, a female mold block is fixedly installed on the top face of the base, a pair of first sliding grooves are symmetrically formed in the positions, located on one side of the female mold block, of the top face of the base, and a pushing plate is slidably connected into the pair of first sliding grooves; and one ends of threaded rods are in threaded connection with the interior of the pushing plate and located in the pair of first sliding grooves, the other ends of the threaded rods penetrate through the first sliding grooves and extend out of one side of the base, and a male mold block is fixedly connected to the side face of the pushing plate. According to the injection mold, cooling liquid is injected into the male mold block and a cooling box, then a water pump circulates the cooling liquid in the male mold block and the cooling box, so that the surface of the male mold block is kept at a low temperature all the time, a second motor rotates to drive the threaded rods to rotate, the threaded rods drive the male mold block to move towards the female mold block containing a molten plastic material until the male mold block enters the female mold block, the molten plastic material is extruded to be formed, and then the molten plastic material is brought out of the female mold block by the male mold block.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a trash can and an injection mold thereof. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. Since injection molds are of great help to production efficiency, more and more plastic processing factories are using injection molds. However, some small injection molds on the market currently have a situation where the cooling of the device is not obvious, which directly leads to molded products. It is difficult to demo...
