Abstract

The utility model relates to an extruder die with easy maintenance. The utility model belongs to industries of extruder manufacture as well as rubber and plastic production. The extruder die is a key component of size of rubber and plastic extruding equipment, and is used for producing extruding products having a definite section shape, for example, the summary attached drawing is a spacial pattern of a thread pressing die in the production of a tyre. The rubber and plastic products have a deformation having complex factors in press extruding process, so the size of die cavity of the die needs repeated burnishing mode to be amended towards new sized products, and thus exact product size can be obtained. On the other hand, the extrusion of the products can cause abrasion of the die; the die of which the size is overproof after abrasion also has repair difficulty. Due to the reasons, the sizing time of the die is long in the production processes, and the difficulty of consistency guarantee of each die is great. The utility model changes an integral type die into a discrete die by changing the structure of the pressing die, and the die is divided into a framework part and a die cavity part; the die cavity part is partitioned into independent modules; the modules are assembled and arranged in the framework, and can be freely replaced. Thus the size of the die cavity can be conveniently changed and the die does not need to be burnished, so the adjustment of the size of the die is easy, and the efficiency of production arrangements is increased and the maintenance cost is reduced; secondly, the change of the size of the die is much standard, the fluctuation and change of pressing size of the products brought by the replacement of the die can be reduced in a vast scale, and the quality and the cost of the pressing products can be effectively guaranteed.

Description

The extruder die of easy care

Affiliated technical field

The utility model belongs to the extruder manufacturing, rubber, plastic products production industry.

Background technology

Extruder die is the critical component of a control extruded product size of rubber, plastics extrusion equipment, existing extruder die is monoblock type or two lobe formulas, but the die cavity of its controlling dimension part all is whole, two lobe formulas just can come out die cavity, be convenient to mode correction cavity dimension, generally connect with screw rod with machining.Accompanying drawing 1.

The shape of the mouth as one speaks directly is connected with extruder, as accompanying drawing 2.The shape of the mouth as one speaks (3) is put into the shape of the mouth as one speaks groove (2) on the head (6); Lower plugboard (4), upward plate (5) motion up and down respectively are locked at the shape of the mouth as one speaks in the shape of the mouth as one speaks groove; Raw material such as rubber, plastics enters the shape of the mouth as one speaks by machine barrel (1) pressurization of band screw rod from discharging opening (7), by obtaining the extruded article of certain cross dimensions after the shape of the mouth as one speaks.The shape of the mouth as one speaks of different cavity dimensions can obtain the extruded product of different section size.

Summary of the invention

The purpose of this utility model is: the extruder die that a kind of easy care is provided, longer in order to the working time that shape of the mouth as one speaks reparation or renewal in solution tire, the plastic industry production process need, dimensional uniformity is relatively poor after changing the shape of the mouth as one speaks, thereby influences rubber, the efficient of plastic products extrusion and the problem of quality.

The utility model solves technical scheme that its technical problem adopts: the monolithic devices die cavity shape of the mouth as one speaks is separated into frame part and die cavity part; Frame part can be general, and promptly the goods shape of the mouth as one speaks of different section shape can a shared framework.Die cavity partly is divided into independently module, and module is made into the standard size of all size, adjusts die cavity somewhere size and only need change this place's module; Design has the groove that is easy to assemble, module combinations to be assemblied in formation model integrated curved in the framework on framework and the module; Module has identical fitted position, can freely change each other.

The beneficial effects of the utility model are: can effectively save the working time of safeguarding the shape of the mouth as one speaks, for example the working time that the tyre surface shape of the mouth as one speaks is safeguarded in tire production process can be shortened to 0.5 hour by original 8 hours.Use the standard module operation, the shape of the mouth as one speaks is safeguarded before and after (replacing), can control the uniformity of die size accurately, thereby guarantees the extruded article quality.

Fig. 5: shape of the mouth as one speaks assembling embodiment figure.

The specific embodiment

1, with the original shape of the mouth as one speaks such as accompanying drawing 3 redesigns, somatotype becomes frame part (1) and die cavity part (2), and the frame part die cavity partly processes fitting recess and the positioning step (3) that coincide mutually; (4) be shape of the mouth as one speaks curve.

2, die cavity part somatotype is the module with standard fitted position A, as accompanying drawing 4.The size of size A depends on the measure of precision that the shape of the mouth as one speaks requires, and accurate more, the A value is more little.For the common shape of the mouth as one speaks, can adopt 10mm.

3, as accompanying drawing 4, with the B of differing heights, the module that C makes all size, wherein B can equal C.The measure of precision that how much also depends on shape of the mouth as one speaks requirement of module specification, accurate more, the B of close module, C value differ more little, and the quantity of the module specification that needs is just many.For the common shape of the mouth as one speaks, can adopt the 0.3mm calibration.

When 4, using the new size shape of the mouth as one speaks: (1) is decomposed into the module specification of each position with the die size that simulates, and is arranged in a sequence number, and respective modules is ready to.(2) as accompanying drawing 5, according to the order of sequence with module D,, embed shape of the mouth as one speaks framework by dress die orifice E, last clamping screw is screwed in by screw F, compresses all modules.(3) will to head, extrude on the die panel.(4), and reselect shape of the mouth as one speaks module according to extruded article shape adjustments simulation size.(5) repeat to replace module, make product size up to standard.(6) note module serial number after up to standard as the parameter of shape of the mouth as one speaks specification.

5,, only need to select new shape of the mouth as one speaks module to replace and get final product according to the module serial number that begins to fix for the extruder die of serious wear.

Can prepare or repair extruder die fast like this.Product size can keep very high uniformity.Can be processed as the new module of B, specification that the C size is littler for the module of wearing and tearing, can not scrap easily.Because it is quite convenient to change module, for the not high extruder die of frequency of utilization, all right common frame also can effectively reduce maintenance cost.

Claims (1)

1. The extruder die of easy care is used for rubber, plastic industry use, and its architectural feature is: the shape of the mouth as one speaks is divided into frame part and die cavity part, and die cavity partly is divided into independently module, and module combinations is assemblied in the framework, and module can freely be changed.
