Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of injection molds, in particular to a mold supporting device of an injection molding machine. Background Art
[0002] Injection molding machine is a kind of equipment used to produce plastic products. It has the advantages of low cost and high efficiency. The principle is to heat plastic particles or powder to a molten state and inject it into the mold. After the hot-melt plastic cools and takes shape in the mold, the cavity of the mold is moved to demould the product. After the product is demoulded, the cavity is reset. The cavity of the mold is made of cast iron, and it slides on the horizontally placed guide pillars. The weight is borne by the guide pillars. The cavity of the mold is sleeved on the guide pillars, which will cause the guide pillars to deform. The deformation of the guide pillars accumulated over a long period of time will affect the reciprocating motion of the cavity. In addition, the cavity quickly fits on the plate where the core is located when it is reset. The rapid fitting and impact will affect the equipment and the alignment of the cavity and the core, affecting the injection molding effect of the product.
