Mold for upper cover of junction box

Abstract

The invention provides a mold for an upper cover of a junction box. The mold comprises a top plate, an upper heat insulation plate, an upper mold plate, a lower mold plate, a lower heat insulation plate, a bottom plate and a mold pressing slot, wherein the upper heat insulation plate is arranged on the lower surface of the top plate; the upper mold plate is arranged on the lower surface of the upper heat insulation plate; the lower mold plate is arranged on the lower surface of the upper mold plate, and a mold cavity is defined between the upper mold plate and the lower mold plate; the lower heat insulation plate is arranged on the lower surface of the lower mold plate; the bottom plate is arranged on the lower surface of the lower heat insulation plate; the mold pressing slot is formed between the upper mold plate and the lower mold plate and endowed with a gradient. According to the mold provided by the invention, an original mold pressing slot is endowed with a gradient, so that the size of a mold pressing surface is increased, and more than two plates can be pressed; the firm fixation of the mold on a machine table is ensured, the dislocation and the damages of the mold, which are caused by poor fixation, can be avoided, and the product quality is further improved.

Description

technical field [0001] The invention relates to a mold for an upper cover of a junction box. Background technique [0002] Injection mold is an important process equipment for the production of various industrial products.
