Extruder mouth-type plate, use method and extruder adopting mouth-type plate

Abstract

The invention relates to an extruder mouth-type plate and an extruder adopting the same. The extruder mouth-type plate comprises a mouth-type seat fixed to an extruder head, a supporting beam born by the mouth-type seat, and two or more relatively movable adjusting blocks connected to the supporting beam, wherein the mouth-type seat, the supporting beam and the adjusting blocks form an extrusion hole. Compared with the prior art, the problems of difficult complicated design and processing and high manufacturing cost of an extruder head of a conventional extruder are solved, the design of the mouth-type plate which is easy to design, simple to process and convenient to modify is adopted, the adjustable extrusion hole is formed by the mouth-type seat, the supporting beam and the adjusting blocks, a plurality of different runners and the outlet-shaped mouth-type plate can be configured through the extruder head of a set of extruder for extrusion molding of products with different raw materials, different flow parameter requirements and different product shapes and sizes, the extruder is multifunctional, the design and processing costs of the extruder are reduced, and the equipment purchasing costs of manufacturers are reduced.

Description

technical field [0001] The invention relates to an extruder die plate, a use method and an extruder using the die plate. Background technique [0002] The rubber extrusion molding equipment mainly uses the joint action of the extruder head and the molding die to extrude the uniformly mixed rubber. If the traditional rubber extruder wants to extrude rubber products with smooth surface and uniform shrinkage section size, there are very high requirements for the flow channel design of the extruder head. The improvement of appearance requirements will increase the design length and difficulty. However, this type of extruder head is not only expensive, but also difficult to adjust the flow path once it is formed. A single extruder head cannot simultaneously meet the extrusion molding of rubber materials with different flow properties and different shrinkage degrees to produce products of the same size. Requirements, the machine head cannot be replaced frequently, increasing the...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned shortcomings in the prior art that the design of the extruder head is complicated and the head cannot be replaced frequently, the present invention provides an extruder die plate, which meets the needs of stable and uniform extrusion molding of raw materials with different flow parameters , It also solves the current situation that the extruder head is expensive to set up, the design is difficult, and the single head is difficult to meet the extrusion molding of different raw materials
