Abstract

The invention discloses an extruding molding device. The extruding molding device comprises a feeding mechanism and a shaping mechanism, wherein the feeding mechanism is used for extruding raw materials into the shaping mechanism to be shaped; the feeding mechanism comprises a machine barrel communicated with the shaping mechanism, a screw rod (12), a heater (13), a hopper (14) and a motor (15); the hopper is vertically arranged above the machine barrel and is communicated with the machine barrel; the heater is arranged on the outer side wall of the machine barrel; one end of the screw rod extends into the machine barrel and the other end of the screw rod is connected with the motor by a retractable rod (16); the motor can drive the screw rod to rotate around the axial direction and moves along the length direction of the screw rod, so that the raw materials melted in the machine barrel are extruded out of the machine barrel to be conveyed to the shaping mechanism; and a non-return valve (17) is arranged in the machine barrel and the non-return valve can be tightly combined with the end part of the screw rod to seal the inner cavity of the machine barrel. The extruding molding device can be used for preventing high molecular materials from a reverse flow phenomenon in an extruding molding process, and the success rate of extruding molding is improved.

Description

technical field [0001] The invention relates to an extrusion molding device. Background technique [0002] The rubber in the extruder is stirred, mixed, plasticized and compacted in the barrel with the aid of the extrusion screw, and then moves towards the machine head, and finally extrudes a product of a certain shape from the shaping die, and then it is cooled and finally shaped. The head of the extruder is often blocked by raw materials during the extrusion molding operation. At this time, when the screw continues to advance, it is easy to cause counterflow of the polymer raw materials, which affects the normal extrusion and shaping operation. Contents of the invention [0003] The object of the present invention is to provide an extrusion molding device, which can prevent the reverse flow of polymer materials during the extrusion molding process and improve the success rate of extrusion molding. [0004] In order to achieve the above object, the present invention prov...
