Abstract
The utility model relates to a fluorine-coated ring forming mold mainly used for producing a fluorine-coated ring which is pneumatically sealed or hydraulically sealed, reciprocates and rotates. The fluorine-coated ring forming mold consists of an upper mold, a lower mold and a pressing cover, wherein an included angle between the parting surface of the upper mold and the horizontal direction is 45 DEG; the inner diameter D (of a mold) is equal to D (of a product) multiplied by the sum of 1 and the inner diameter shrinkage rate; the section diameter d (of the mold) of the mold is equal to d (of the product) multiplied by the sum of 1 and the section shrinkage rate; the parting surfaces of the lower mold and the upper mold are consistent; included angle between each parting surface and the horizontal direction is 45 DEG; the dimensions of cavities of the lower mold and the upper mold are consistent; the pressing cover and the lower mold are assembled together; the included angle between the internal surface of the pressing cover and the horizontal direction is 45 DEG; and the internal surface of the pressing cover and a 45-DEG surface at the inner side of the mold are on the same curved surface. The utility model provides the novel fluorine-coated ring forming mold aiming to solve the practical problems of difficulty in forming of a fluorine-coated ring product, low yield and the like in the production. Compared with a conventional mold with a common structure, the novel fluorine-coated ring forming mold has the advantage that the production yield of the fluorine-coated ring can be greatly improved.
Description
One technical field
The utility model relates to a kind of bag fluorine circle mould, and it is mainly for the production of the reciprocal bag fluorine circle with rotatablely moving of pneumostop or hydraulic packing.
Two technical backgrounds
Mould molding is one of major way of rubber product forming, because the unreasonable moulding process of rubber that causes of Design of Dies is difficult, product percent of pass is low sometimes, and outward appearance does not reach the practical problems such as instructions for use.Therefore, whether can Design of Dies rationally implement to have vital meaning to production process smoothly.It is low such as qualification rate that bag fluorine circle Novel die structure is met in can solving and producing in the past, the problems such as product appearance defective.
Three summary of the invention
The purpose of this utility model is to provide a kind of coating fluoroplastics O type rubber seal mould---bag fluorine circle mould.
The purpose of this utility model is achieved like this: the utility model is made of upper die and lower die, gland three parts, and the die joint of upper die mold is from the horizontal by 45 degree angles, the inner diameter D of mould
Mould=D
Product* (1+ internal diameter shrinkage factor), mould cross section diameter: d
Mould=d
Product* (the 1+ contraction percentage of area); The die joint of counterdie die joint and upper die structure is consistent, die joint is all from the horizontal by 45 degree angles, be arranged with die cavity on upper die and lower die, the cavity dimension of upper and lower mould is consistent, gland and counterdie are assembled together, the inner surface of gland is also from the horizontal by 45 degree angles, and its inner surface should be with 45 kilsyth basalt faces of mould inboard on same curved surface.
A kind of new structure of designing through improving on the basis of the practical problems such as the utility model is difficult for bag fluorine circle formed product in producing, and qualification rate is low.The same mould of ordinary construction is in the past compared, and this structure can improve the production qualification rate of bag fluorine circle greatly.
Four, description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the structural representation of patrix of the present utility model.
Accompanying drawing 3 is the structural representation of counterdie of the present utility model.
Wherein: 1----patrix, 2----counterdie, 3----gland, 4--die cavity.
Five, the specific embodiment
Come the utility model is done carefully to describe furtherly below in conjunction with drawings and Examples.
With reference to accompanying drawing, the utility model bag fluorine circle mould comprises that patrix 1, counterdie 2, gland 3 three parts consist of, and the die joint of patrix 1 mould is from the horizontal by 45 degree angles, the internal diameter of mould: D
Mould=D
Product* (1+ internal diameter shrinkage factor), mould cross section diameter: d
Mould=d
Product* (the 1+ contraction percentage of area); Counterdie 2 die joints are consistent with the die joint of patrix 1 structure, die joint is all from the horizontal by 45 degree angles, be arranged with die cavity 4 on patrix 1 and counterdie 2, the cavity dimension of counterdie 2 is consistent with the cavity dimension of patrix 1, gland 3 is assembled together with counterdie 2, the inner surface of gland 3 is also from the horizontal by 45 degree angles, and its inner surface should be with 45 kilsyth basalt faces of mould inboard on same curved surface.
