Bi-module-injection plastic extrusion and injecting molding machine

Abstract

The invention discloses a bi-module-injection plastic extrusion and injecting molding machine which comprises an injecting machine body (1), a module assembling machine body (2), an extruding and injecting device and module assembling devices (3), wherein the extruding and injecting device is arranged on the injecting machine body (1), and the module assembling devices (3) are fixed on the module assembling machine body (2). The bi-module-injection plastic extrusion and injecting molding machine is characterized in that the injecting machine body (1) is provided with a dovetail groove guide rail (9); the module assembling devices (3) are two; the extruding and injecting device comprises an integral inlet base (4), a horizontally moving slide seat (5), an integral inlet oil cylinder (6), an injection component (7) and a plasticized component (8); the lower part of the integral inlet base (4) is provided with a dovetail groove (9) which is sleeved on the dovetail groove guide rail (9), and the upper part of the integral inlet base (4) is provided with a horizontal guide post (10); the horizontally moving slide seat (5) is provided with a guide sleeve which is sleeved on the horizontal guide post (10) of the integral inlet base (4); the injection component (7) and the plasticized component (8) are installed on the horizontally moving slide seat (5); and one end of the integral inlet oil cylinder (6) is fixed on the integral inlet base (4), and the other end of the integral inlet oil cylinder (6) is fixed on the module assembling devices (3). According to the invention, a second module is produced by utilizing the cooling time of a first module, the energy consumption is saved, the production efficiency is improved, and the product weights of the two modules can be different.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a one-injection double-mode plastic extrusion molding machine. Background technique [0002] The plastic extrusion molding machine is a new type of plastic injection molding machine. The traditional plastic injection molding machine has only one screw, which not only plays the role of material storage, but also plays the role of injection. Its disadvantage is that the one-time injection volume cannot be too large, and when the screw is retreating, its effective thread is reduced and the plasticizing quality is affected. At present, the domestically produced single-screw reciprocating plastic injection molding machine with a clamping force of 40,000KN has a one-time theoretical injection volume of 62,000cm 3 . The TRX-J plastic injection molding machine manufactured by Terry Machinery Co., Ltd. has a clamping force of 40,000KN, and its one-time theoretical injection vol...

Problems solved by technology

Its disadvantage is that the one-time injection volume cannot be too large, and when the screw is retreating, its effective thread is reduced and the plasticizing quality is affected.

It can be seen that in the production of extra large and heavy plastic products, the cooling time accounts for more than 1/2 of the entir
