Abstract

The invention discloses a hot-press forming die for a conical cover. The hot-press forming die comprises: an upper die, including a cone body, an upper die oil circuit system and a plurality of positioning blocks located around the cone body. There are a plurality of chutes, and the upper mold oil circuit system is arranged in the chute; the lower mold is provided with an inner cavity, and the inner cavity includes a feeding cavity that matches the shape of the cone and a feeding cavity that matches the shape of the feeding cavity. Connected mold plug cavity, the lower mold is also provided with a lower mold oil circuit system, the plurality of positioning blocks are clamped on the lower mold; the upper demoulding ring; the lower demoulding plug; the backing plate is fixed on the On the lower mold, it is used to fix the lower knockout plug. This application designs a reasonable oil heating pipeline system and upper and lower positioning block positioning and guiding structures according to the structural characteristics of the conical cover. The oil heating pipeline system makes the mold easily meet the temperature uniformity requirements, and there is no repair in the trial mold problem, 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...
