Abstract
The invention relates to a composite die, comprising an outer die and an inner die. The composite die is characterized in that the outer die is a hard die, the inner die is a flexible die, the inner die is adhered to the inner wall of the outer die, and the outer die and the inner die are fixed together by virtue of bolts and nuts. The composite die provided by the invention has the advantages that the moulding surface has less possibility of being worn down, the die is easy to repair, the service life is long, the cost is saved, and technical conditions are simple.
Description
Technical field
The invention belongs to a kind of mould, especially relate to a kind of composite die, it is the product of raw material that resin is adopted in main manufacturing.
Background technology
So-called mould be exactly on the industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that method such as casting, moulding, smelting, punching press, stretching obtains required product.In brief, mould is to be used for the instrument of formed article.The height of Tool and Die Technology level is an important symbol of weighing manufacturing industry level height.
Manufacturing the employing resin is in the product process of primary raw material, the production mould that is adopted is a fiber reinforced plastic mold, when adopting fiber reinforced plastic mold to manufacture product, though it is accurate to have product-forming, on-deformable advantage, the product of the moulding complexity that exists can only many sub-modules could the demoulding, and influence the quality of product, must use demoulding wax again before each the production, have shortcoming time-consuming and that cost is high, so this mould is to being fit to the simple production of moulding.At the existing defective of fiber reinforced plastic mold, it is the product of primary raw material that the silica gel of people's employing at present fiberglass composite die is manufactured with the resin, its internal layer of silica gel fiberglass composite die adopts the silica gel soft mode, the outer fiberglass die that adopts, must not use demoulding wax again before the production, it has solved the problem of moulding complex product demoulding difficulty.But owing to be not mutually bonding between the silica gel soft mode of the internal layer of existing silica gel fiberglass composite die and the outer field fiberglass die, so in actual applications, exist the product easy deformation of being produced with the firm composite die of common silica gel ratio, the inaccurate weak point of moulding.
Summary of the invention
At above-mentioned defective, the objective of the invention is to, a kind of composite die is provided, it is the product of raw material that resin is adopted in main manufacturing, and it is simple in structure, and the product-forming of being produced is accurate, is easy to the demoulding, need not use demoulding wax, has reduced cost.
For achieving the above object, technical scheme of the present invention is a kind of composite die, comprise external mold and internal mold, described external mold is a die, and described internal mold is a soft mode, described internal mold is attached on the inwall of external mold, is fixed together by screw bolt and nut between external mold and the internal mold.
In a preferred embodiment of the present invention, the outer wall both sides of described external mold are provided with support.
In a preferred embodiment of the present invention, respectively be provided with a bolt hole on the support of described both sides.
In a preferred embodiment of the present invention, described external mold is to be made by the material of glass-reinforced plastic material or similar fiberglass.
In a preferred embodiment of the present invention, described internal mold is to be made by the material of silica gel material or similar silica gel.
The composite die that the present invention discloses, it is the product of raw material that resin is adopted in main manufacturing, comprise external mold and internal mold, internal mold is a soft mode, is fixed together by screw bolt and nut, it is simple in structure, the product-forming of being produced is accurate, and internal mold is that silica gel is made, and is easy to the demoulding, need not use demoulding wax, reduce cost.
Description of drawings
Accompanying drawing 1 is the structural representation in composite die cross section in the embodiment of the invention;
In the accompanying drawing, 1 is external mold, and 2 is internal mold, and 3 is support, and 4 is bolt, and 5 is nut, and 6 is bolt hole.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
As shown in Figure 1, structural representation for composite die cross section in the embodiment of the invention, the invention provides a kind of composite die, comprise external mold 1 and internal mold 2, external mold 1 is the die of being made by glass-reinforced plastic material, and described internal mold 2 is soft modes of being made by silica gel material, and internal mold 2 is attached on the inwall of external mold 1, wherein, be fixed together by bolt 4 and nut 5 between external mold 1 and the internal mold 2.
The outer wall both sides of external mold 1 are provided with support 3, respectively are provided with a bolt hole 6 on the support 3 of both sides, and bolt 4 is fixed by nut 5 after being interspersed in the bolt hole 6, makes the product-forming of being produced accurate, and is not yielding.
External mold 1 is to be made by glass-reinforced plastic material in the embodiment of the invention, fiberglass formal name used at school fiberglass reinforced plastics.It is as reinforcing material, to make a kind of composite of matrix material with glass fibre and goods (glass cloth, band, felt, yarn etc.) thereof with synthetic resin.Fiberglass has following advantage: high-strength light, corrosion resistance and good, good electrical property, hot property is good, designability good, manufacturability is good etc.Its performance is suitable for making mould very much.
The composite die that the present invention discloses, it is the product of raw material that resin is adopted in main manufacturing, comprise external mold and internal mold, internal mold is a soft mode, is fixed together by screw bolt and nut, it is simple in structure, the product-forming of being produced is accurate, and internal mold is that silica gel is made, and is easy to the demoulding, need not use demoulding wax, reduce cost.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
Claims (5)
