Abstract

The invention discloses a hot pressing mold of a conical cover. The hot pressing mold comprises an upper mold, a lower mold, an upper mold stripping ring, a lower mold stripping plug and a cushion plate, wherein the upper mold includes a cone, an upper mold oil way system and multiple positioning blocks positioned around the cone; multiple chutes are formed in the cone; the upper mold oil way system is arranged in the chutes; the lower mold is provided with an inner cavity; the inner cavity includes a charging cavity matched with the cone in shape, and a mold plug cavity communicated with the charging cavity; a lower mold oil way system is additionally arranged in the lower mold; the multiple positioning blocks are clamped on the lower mold; and the cushion plate is fixed on the lower mold, and is used for fixing the lower mold stripping plug. The hot pressing mold designs reasonable oil heating pipeline system and positioning guide structures of upper and lower positioning block according to structural characteristics of the conical cover; the oil heating pipeline system enables the mold to easily reach the temperature uniformity requirement; no repair problem is generated in mold trial; and the heating efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic compression molding, in particular to a hot compression molding die for a conical cover. Background technique [0002] The FRP molding process is to put the prepared glass fiber and resin premix into the concave mold of the preheated metal mold, and the premix is ​​filled between the convex and concave molds of the mold under the action of mold clamping pressure. In this way, the FRP product with the same shape as the mold cavity is formed by molding, and then continue to heat up to make the resin further undergo cross-linking reaction and solidify. After reaching a certain holding time, let the mold cool down and get the required FRP molded products. [0003] A certain conical cover is a key part of the model product. It is a conical cylindrical structure with one end closed, and its forming dimensional accuracy is high. The existing mold is heated by electric heating tub...
