Injection machine

Abstract

The invention relates to an injection molding machine, which comprises a feeding device and a mould closing / opening device. The feeding device comprises at least one feed stirring device, wherein the feed stirring device also comprises two parallel threaded rods which are used for stirring fed materials, and are provided with screw threads and ribs on the surfaces respectively; the mould closing / opening device also comprises a top plate, a rolling shaft and a second transmission device; the top plate is movably connected to one side of a moveable plate close to a mould adjusting plate; and the rolling shaft is connected with one end of the top plate close to the mould adjusting plate; and the top plate is connected with the second transmission device which can drive the top plate to move up and down. Implementation of the injection molding machine has the advantages that the lengths of two parts occupying space mostly of the prior injection molding machine are greatly reduced, so that the occupied space of the machine can be greatly reduced, and effective utilization of production space can be favored.

Description

technical field [0001] The present invention relates to mechanical equipment, and more particularly, to an injection molding machine. Background technique [0002] Injection molding machine is a very common machine used by people in modern industrial production. Its principle is to heat the plastic raw material to melt it to obtain a melt formed by the plastic raw material. The injection molding machine injects the melt into the pre-prepared In the mold, the product is obtained after the melt injected into the mold cools down. In modern industry, the requirements for injection molding products are getting higher and higher. It is often necessary to add various pigments or other plastic materials with different components to the plastic raw materials. Although the current injection molding machines can also complete the production, adding various Pigment or other plastic raw materials with different components are prone to uneven distribution of the pigment or other plastic ...

Problems solved by technology

In modern industry, the requirements for injection molding products are getting higher and higher. It is often necessary to add various pigments or other plastic materials with different components to the plastic raw materials. Although the current injection molding machines can also complete the production, adding various Pigment or other plastic raw materials with different components are prone to uneven distribution of the pigment or other plastic raw materials with different components in the main plastic raw materials, and in order to solve the above problems to a certain extent, the general method is to lengthen the feeding device length, which makes the length of the injection molding machine longer; at the same time, the opening / closing device of the injection molding machine mostly uses a hydraulic device plus a curved rod. Under the action of the hydraulic device, the curved rod will Push to the fixed plate with the fixed mold, make the movable mold and the fixed mold together, and generate and maintain a certain pressure through the hydraulic device and the crank rod, so that the movable mold is close to the fixed mold, and then injection molding; after the injection molding is completed Finally, the hydraulic device pulls the movable plate back, separates the movable mold from the fixed mold, takes out the product, and then proceeds to the next cycle of injection molding

Due to the use of curved rods (usually four-section curved rods) in the prior art, the weight is also relatively large, and due to the error superposition of multi-section curved rods, the mold locking accuracy is low, and the length of the injection molding machine is further increased at the same time. Increase the floor area of ​​the injection molding machine, thereby increasing the production cost
