Problems solved by technology

First, the extrusion efficiency is higher, but the shaping and cooling are slower
Second, the dimensional accuracy and surface quality of the profile are not ideal
The temperature of the forming mold is generally transmitted to the shaping mold, and the temperature of the shaping mold is too high to affect the quality of the product

specific Embodiment approach

[0007] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: Further description will be made below in conjunction with the accompanying drawings.

[0008] As shown in the accompanying drawing, the water circulation device of the plastic extruder stereotypes consists of a cooler, a water pump and a water tank. There is a cross-sectional shape between the forming die 4 connected to the connecting plate 5 on the extruder 6 and the setting die 1, which is the same as them, and the extruded profile around the die forms an annular, hollow inner cavity, and a belt on the shell. There is the cooler 2 of water inlet and outlet 3, forming die, cooler and setting die are connected and fixed into one by connecting ear 10.

[0009] Described cooler has a radiator water tank 7, forms water circulation device by water pump 8 through pipeline. This water circulation device blocks the heat transfer from the forming die to the calibrating die.

[0010] On the pipeline that cooler is connected w...

Abstract

The invention discloses a water circulation device for a plastic extruder stock mould and belongs to the field of plastic processing machines. The water circulating device is arranged between a forming mould connected with an extruding cylinder and the stock mould, wherein the shape of the section of the water circulation device is the same as that of the forming mould and the shape of the stock mould, and a hollow shell of an inner cavity of the water circulation device is provided with a water input and output opening. Water circulation is formed in the inner cavity of the water circulation device through a water input and output pipe. The water circulation device weakens intensity of transmitting heat from the forming mould to the stock mould, the heat is taken away by means of water circulation, cooling speed of the stock mould and plastic profiles is increased, and the stock mould is controlled to reach ideal cooling speed, so that product quality is ensured.

Description

technical field [0001] The invention relates to a plastic processing machine, in particular to a cooling device for a plastic extruder. Background technique [0002] In the prior art, the domestic mold manufacturing of plastic extruder still has a large gap compared with the advanced level, which is mainly manifested in the restrictive factors of plastic extrusion speed and quality. One is that the extrusion efficiency is higher, but the shaping and cooling are slower. The second is that the dimensional accuracy and surface quality of the profiles are not ideal. This is all related to the design of the cooling and setting device of the extrusion die. The temperature of the forming die is generally transmitted to the calibrating die, and the high temperature of the calibrating die will affect the quality of the product. For example, micro-foaming occurs in the product crust, the surface is rough and not smooth, the hardness is poor, and it is easy to decolorize. Contents...
