Embodiment

[0025] Such as figure 1 with figure 2 As shown, a silicone rubber insulator injection mold demoulding device is composed of a lower template 16, a lower hot plate 17, a movable template 18, a mandrel 15, a demoulding cylinder 1-8 and a movable insert 9-14, wherein the lower The template 16 is fixed on the upper end of the movable template 18, and a lower hot plate 17 is arranged between the two, and the mandrel 15 is correspondingly placed in the cavity of the lower template 16, and the movable inserts 9-14 can slide up and down from left to Right is arranged at the lower end of the mold cavity of lower template 16, and movable insert 9-14 is symmetrically distributed on the left and right sides of lower template, and the upper end of movable insert 9-14 can protrude from the mold cavity of lower template 16, and its upper end The shape corresponds to the shape of the cavity surface of the lower formwork 16. Before the movable inserts 9-14 are jacked up, the upper end thereo...

Abstract

The invention discloses a silicon rubber insulator injection mold demolding device. The device comprises a moving template, a lower template, a lower heat plate, a mandrel, at least three movable inserts and a driving mechanism, wherein the lower template is fixedly arranged at the upper end of the moving template; the lower heat plate is fixedly arranged between the moving template and the lower template; the mandrel is placed in a cavity of the lower template; the movable inserts are arranged in the cavity of the lower template in a vertical sliding mode, the shapes of the upper ends of the movable inserts correspond to the shape of the cavity of the lower template, so that the movable inserts are combined with the cavity of the lower template to form a cavity of a product, and the at least three movable inserts are distributed along the axial direction of the cavity of the lower template; the driving mechanism is fixedly arranged on the movable template and is connected with the movable inserts to drive the movable inserts to slide up and down. According to the device, automatic demolding can be performed on the product, the production efficiency is high, and the product is not damaged easily.

Description

technical field [0001] The invention relates to a silicone rubber injection mold, in particular to a demoulding device for a silicone rubber insulator injection mold. Background technique [0002] Most of the existing silicone rubber insulators used for power transmission and transformation lines are injection molded. Due to the strong pressure during injection, after the product is formed, it is squeezed very tightly with the mold cavity. However, because the composite insulation molding technology has not been used for a long time, the length of the insulator product formed at one time generally does not exceed 1.5m. The length is relatively short, and the force required to separate from the mold is still within the reach of manpower, so currently the product is separated from the mold by hand. With the development of high-voltage and ultra-high-voltage power transmission and transformation industries, the demand for high-voltage insulator products is increasing, and the ...
