Abstract
The composite mould possesses a metallic outer cover and an imitable internal mould made of elastically deformable material which can be rubber, plastics or their composite material. Said internal mould is pressed to the internal wall of the outer cover. Said composite mould not only possesses the characteristics of metal mould, such as high mechanical strength, long service life, non-deforming and good compression strength, but also has the advantages of rubber mould, such as good imitation property, easy to demould and simple and convenient processing, etc..
Description
The present invention relates to a kind of mould, but particularly relate to a kind of composite die that is used for production nonmetallic materials product with emulation internal mold.
In the industrial products production process, people often need design the production in enormous quantities that the various moulds of processing are realized product.According to the difference of product category, mould also is divided into polytype.In mechanical processing industry, using maximum is metal die.Metal die has the mechanical strength height, long service life, and advantage such as not yielding, but the metal die process-cycle is long, the requirement on machining accuracy height, and the mould cost is also higher.In addition, metal die exists problems such as being difficult for the demoulding when being used for the machining of non-metallic material product and having the product of complexity body.For this reason, people add at the said goods and have adopted thermoplastic elastomer mould or plastics mould man-hour.This mold releasability is easy, but intensity is low, and resistance to pressure is poor, and mould is yielding.In addition, processing for some product, as the art work, industrial cured type and plastic products etc., require mould that higher fidelity is arranged, to process form product true to nature, simultaneously require mould to have certain intensity again, can not be out of shape under pressure, do not emerge but still there is the mould that meets above-mentioned requirements up to now.
The object of the present invention is to provide a kind of higher mechanical strength that both had, be easy to the demoulding again, and have the composite die of better emulation.
For achieving the above object, but the invention provides a kind of composite die, but this composite die is to be provided with an emulation internal mold 2 of being made by deformable material in metal-coating 1 with emulation internal mold.
The described deformable material that is used to manufacture internal mold can be the composite of rubber, plastics or rubber and plastics.
Described internal mold 2 is pressed on the inwall of external mold 1.
But the composite die with emulation internal mold of the present invention can be used for manufacturing the nonmetallic materials product, particularly the art work of curing molding material, industrial cured type, plastic products and low-melting alloy etc. voluntarily.
The present invention integrates metal die and rubber-like mould, has both overcome the defective separately of two kinds of moulds, has the characteristic of both excellences again simultaneously.This composite die not only has metal die mechanical strength height, and long service life is not yielding, characteristics such as good pressure-resistant performance, and have rubber-like mould good simulation, and be easy to the demoulding, process advantages such as easy.The present invention also has and manufactures simply, and cheap characteristics, the cost of this composite die only be dried/one of metal die.Therefore can reduce production costs greatly.
Fig. 1 is a structural representation of the present invention.
Provide the preferred embodiments of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, but but the composite die with emulation internal mold of the present invention is to be provided with an emulation internal mold 2 of being made by deformable material in steel bushing 1.Above-mentioned deformable material can be the composite of rubber, plastics or rubber and plastics.In this preferred embodiment, internal mold adopts silicon rubber to make, and is conformable to moulding on the inwall of steel bushing 1 by pressurization.Concrete manufacture technology is as follows: the silica gel that mixes up is evenly coated on the model of required moulding, silica gel thickness can be decided according to the required pressure size of want molding materials, is about 3 millimeter in this example.The model that coats silica gel is put into steel bushing 1,, the silica gel internal mold is pressed on the inwall of steel bushing 1 by forcing press compacting, treat curing molding after, model is taken out, just made a complete composite die.
During actual production, composite die of the present invention is contained on the press injector, material 4 pressurizations is injected in the cavity of internal mold 2, with the material die cast through die casting tube 3.Because internal mold is to be made by rubber-like silica gel, so when material is pressed into internal mold, the internal mold pressurized outwards produces distortion, because steel bushing 1 is equipped with in the internal mold outside, therefore internal mold is subjected to the steel bushing restriction and closely is coated on the material surface, and make the shape of internal mold, comprise that each trickle part all is replicated on the material, thereby have good emulation.Take out through the product demoulding at an easy rate that this composite die suppresses.
Claims (3)
- But 1, a kind of composite die that is used for production nonmetallic materials product with emulation internal mold, it is characterized in that this composite die be at metal-coating (1) but in be provided with an emulation internal mold (2) of making by deformable material.
- But 2, the composite die with emulation internal mold according to claim 1 is characterized in that the described deformable material that is used to manufacture internal mold can be the composite of rubber, plastics or rubber and plastics.
- But 3, the composite die with emulation internal mold according to claim 1 is characterized in that described internal mold (2) is pressed on the inwall of metal-coating (1).
