A thimble pushing device for plastic mould

Abstract

The invention discloses an ejector pin pushing device for a plastic mold. The ejector pin pushing device for the plastic mold structurally comprises handles, a movable front end mold, telescopic rods,strong springs, raised slideways, a fixed back end mold, an injection molding hole, an injection molding pipe, a U-shaped groove, a middle fixed mold, a mold pressure block, a hinge seat and an ejector pin pushing device; each handle is in an L shape; the inner end surface of each handle is connected to the corresponding telescopic rod in a penetrating manner through a strip notch; the movable front end mold is in a rectangular block shape, is arranged on the right sides of the handles and is telescopically connected with the left end surface of the mold pressure block and the left end surface of the middle fixed mold in a sealing manner through the telescopic rods respectively; the telescopic rods penetrate through the movable front end mold, the mold pressure block and the middle fixedmold and are connected to the handles and the fixed back end mold respectively; and the strong springs are welded to and are elastically connected with the inner sides of the lower parts of the two ends of the mold pressure block respectively. The ejector pin pushing device for the plastic mold has the beneficial effects of having the purpose of realizing that the ejector pin pushing device for the plastic mold can rapidly and effectively push out a formed plastic mold through the ejector pin pushing device, keeping the integrity of a product to the maximum, lowering the surface damage degreeand improving the production good quality of a workpiece.

Description

technical field [0001] The invention relates to a thimble pushing device for plastic molds, which belongs to the field of thimble pushing devices for plastic molds. Background technique [0002] With the rapid development of the plastics industry and the continuous improvement of the strength of general-purpose and engineering plastics, the application range of plastic products is also expanding, and the consumption of plastic products is also increasing. A plastic mold is a tool for producing plastic products. It consists of several groups of parts, and this combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, then the upper and lower molds are separated, and the product is ejected from the cavity through the ejector system to leave the mold, and finally the mold is closed again For the next injection molding, the entire ...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an thimble pushing device for plastic molds, so as to solve the problem that the thimble is often pushed out differently due to special materials, air bubbles, long cooling time, etc. when pushing out plastic molding workpieces. The degree of surface damage reduces the production quality of the workpiece and affects the yield of the product
