Abstract

The utility model relates to a mold and discloses a fluoridating mold. The fluoridating mold comprises a mold core (2) and a mold sleeve (3), wherein the inner surface of the mold sleeve (3) is provided with a fluorine plastic protecting layer (1) and a gap (4) is formed between the mold core (2) and the mold sleeve (3). The surface, which is close to the mold core, of the mold sleeve, is provided with the fluorine plastic protecting layer and fluorine plastic has excellent properties such as dielectric performance, chemical corrosion resistance, high temperature resistance, water resistance, non-adhesion, a low friction coefficient and good self-lubrication, the fluoridating mold which stays under a condition of high temperature for a long time can be prevented from being adhered to plastics, and therefore, the undesirable phenomena such as flaws, scratches and pitted surfaces do not occur on the surfaces of products; besides, the fluoridating mold has the advantages of simple manufacturing process, low cost and the like, and is convenient to maintain; the fluoridating mold can be widely applied to the industrial fields of chemical industry, electronics, electrics, aerospace, semi-conductor, machinery, textile, building, medicine, automobile and the like.

Description

The fluoridize mould

Technical field

The utility model relates to mould, has related in particular to a kind of fluoridize mould.

Background technology

Mould be on the industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is the instrument of formed article, and this instrument is made of various parts, and different moulds is made of different parts; It mainly realizes the processing of article profile by the change of institute's moulding material physical state.Mould of the present utility model comprises core rod and die sleeve, this mould mainly be by high temperature plastics from the slit flow mistake between core rod and die sleeve, thereby the outward appearance of qualitative product and requirement; Conventional mould mainly is metal die, if metal die is in high temperature for a long time, plastics will with slowly adhesion of metal die, cause the product appearance bad phenomenon such as flaw, cut, pitted skin to occur; The product appearance is very coarse, thereby makes product quality not pass a test, and does not reach customer requirement etc.

Summary of the invention

The utility model provides a kind of resistant to elevated temperatures fluoridize mould at above-mentioned shortcoming of the prior art.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

The fluoridize mould comprises core rod and die sleeve, and the inner surface of die sleeve is provided with the fluoroplastics protective layer.Fluoroplastics have excellent dielectric energy, chemical attack, high-low temperature resistant, waterproof, it is sticking not to be stained with, low-friction coefficient and good performances such as self-lubricating.

As preferably, be provided with the slit between core rod and die sleeve.

The utility model is owing to adopted above technical scheme, have significant technique effect: the surface at the close core rod of die sleeve is provided with the fluoroplastics protective layer, fluoroplastics have excellent dielectric energy, chemical attack, high-low temperature resistant, waterproof, it is sticking not to be stained with, low-friction coefficient and good performances such as self-lubricating, can prevent the fluoridize mould for a long time under the situation of high temperature with the plastics adhesion, cause the product appearance bad phenomenon such as flaw, cut, pitted skin to occur; And have advantages such as manufacturing process is simple, with low cost, easy maintenance, can be widely used in industrial circles such as chemical industry, electronics, electric, Aero-Space, semiconductor, machinery, weaving, building, medicine, automobile.

Description of drawings

Fig. 1 is generalized section of the present utility model.

The toponym that each number designation refers in the accompanying drawing is as follows: wherein 1-fluoroplastics protective layer, 2-core rod, 3-die sleeve, 4-slit.

The specific embodiment

Describe in further detail below in conjunction with accompanying drawing and the utility model of embodiment:

Embodiment 1

The fluoridize mould as shown in Figure 1, comprises core rod 2 and die sleeve 3, and the inner surface of die sleeve 3 is provided with fluoroplastics protective layer 1.3 of core rod 2 and die sleeves are provided with slit 4.

During use; when high temperature plastics flows through from the slit 4 of 3 of core rod 2 and die sleeves; fluoroplastics protective layer 1 can make high temperature plastics and die sleeve 3 isolate; because fluoroplastics have excellent dielectric energy, chemical attack, high-low temperature resistant, waterproof, it is sticking not to be stained with, low-friction coefficient and good performances such as self-lubricating; can prevent the fluoridize mould for a long time under the situation of high temperature with the plastics adhesion; cause the product appearance bad phenomenon such as flaw, cut, pitted skin to occur, can protect the outward appearance of product, meet the standard of product.

In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.

Claims (1)

1. the fluoridize mould comprises core rod (2) and die sleeve (3), and it is characterized in that: the inner surface of die sleeve (3) is provided with fluoroplastics protective layer (1), and is provided with slit (4) between core rod (2) and die sleeve (3).
