Description

Technical Field

[0001] The utility model belongs to the technical field of plastic molds, and in particular relates to a plastic mold upper cover pushing structure. Background Art

[0002] A plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes. The production of plastic parts by the plastic mold is formed by the extrusion of the convex and concave molds, generally referred to as the upper cover and the lower cover. The lower cover is basically fixed on the workbench and does not move. The upper cover is pushed by a hydraulic device for extrusion or injection molding. Application No. 202222678193.9 describes a plastic mold upper cover pushing structure, including a hydraulic press body, a mold upper cover body is connected to the bottom of the hydraulic press body, the lower end of the hydraulic column in the hydraulic press body is fixedly connected to a push plate, the push plate is fixedly connected to the four corners of the side away from the hydraulic press body with a first connecting column, the first connecting column is threadedly connected to the second connecting column, one end of the four second connecting columns is sleeved with a mounting plate, the second connecting column is threadedly connected to the first nut at the end away from the hydraulic press body, and the mounting plate is fixedly connected to one side of the mold upper cover body on the side away from the hydraulic press body. This new plastic mold upper cover pushing structure, when the stroke of the hydraulic press body is not long enough, loosen the fixing component and the first nut, rotate the second connecting column, adjust the four second connecting columns to be completely consistent, fix the second connecting column with the first connecting column with the fixing component, tighten the first nut, and achieve the effect of extending the stroke of the hydraulic press body.

[0003] The above technical solution controls the height of the mounting plate by adjusting the four second connecting columns through threads. Since the method of adjusting the four second connecting columns one by one through threads is relatively cumbersome and it is difficult to maintain consistent adjustment distances of the four second connecting columns, there are disadvantages in the accuracy of the stability and levelness of the fixing of the mounting plate.
