Abstract

The invention discloses a thermoplastic phenolic resin forming mold. Parts are few, the structure is simple, mold manufacturing is convenient, the cost is low, cutting force is large, and an oil cylinder drives two or more cutters to simultaneously cut off a sprue. Grooves are formed in the two sides of an upper mold plate in the mold and provided with n-shaped pressing plates, the front ends of the n-shaped pressing plates are provided with inclined T-shaped grooves, the inclined T-shaped grooves are movably connected with T-shaped hook heads arranged at the rear ends of cutter rods, the rearends of the n-shaped pressing plates are connected with a piston rod of the oil cylinder, and the oil cylinder is connected with the upper mold plate. The front ends of the cutter rods are provided with blades, and the cutter rods penetrate through square through holes A, through holes B and through holes C formed in a mold cavity plate and the upper mold plate in a sleeved mode. When press forming pressure maintaining is completed, the oil cylinder works to drive the piston rod to forwards move to drive the cutter rods connected with the n-shaped pressing plates to downwards move so as to generate pressure to cut off the sprue; after the sprue is cut off, the oil cylinder is reset, and the cutter rods are returned; and the mold is opened to take out a formed workpiece without the sprue.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to the technical field of thermoplastic phenolic resin molding molds. Background technique [0002] The advantages of thermoplastic phenolic resin are high heat resistance, good electrical insulation, not easily deformed under pressure, and the dimension of the molded product is stable. Thermoplastic phenolic resin is widely used in the electrical industry. With the improvement of the quality requirements of electrical products, the use of thermoplastic phenolic resin for solid-state mass mold processing is increasing. Existing molds that adopt the transfer method to process the solid mass of thermoplastic phenolic resin do not have the function of removing the gate in the mold. When the product formed by thermoplastic phenolic resin in the mold is connected with the gate, the product is removed After the mold is taken out, the gate needs to be removed, either manually or mechanicall...
