Description

Mould frock is used in vulcanization of corrugate rubber film

Technical Field

The utility model belongs to rubber film production field, concretely relates to mould frock is used in vulcanization of corrugate rubber film.

Background

The rubber film for the oil filling safety valve of a certain model is used as a pressure sensing and sealing element, and outputs certain displacement after sensing pressure.

The corrugated rubber film for the refueling safety valve is produced by putting a semi-finished product into a mold to be vulcanized in a production process, and due to the corrugated depth of the corrugated film, the transition angle between the protruding part of a working surface and the edge of the film is close to 90 degrees. Therefore, it is necessary to design a new mold tool for vulcanizing a corrugated rubber film.

The die tooling replaces the traditional two-die-opening die, and has great help for improving the yield of the film.

Disclosure of Invention

The utility model provides a corrugate rubber film vulcanizes and uses mould frock solves the unbalanced film damage that causes of traditional mould frock atress, the low problem of vulcanization finished product rate.

In order to achieve the above object, the present invention provides a technical solution:

a mold tool for vulcanizing a corrugated rubber film comprises a male mold and a female mold, wherein the male mold and the female mold can be vulcanized to form the corrugated rubber film, the mold tool further comprises a circular upper pressing plate, a plurality of ejector rods, a horn-shaped handle and a sleeve, the male mold comprises a mold body part and an edge part, a plurality of openings are formed in the edge part at equal intervals, the lower end face of the circular upper pressing plate is vertically downwards provided with the plurality of ejector rods, the plurality of ejector rods correspond to the positions of the openings of the male mold, and the plurality of ejector rods penetrate through and extend out of the openings of the male mold; the female die comprises a die body part and an edge part, when the die body part of the female die is tightly matched with a die body of a male die, a plurality of ejector rods are tightly attached to the upper end face of the edge part of the female die, a plurality of groups of horn-shaped handles are annularly arranged on the side wall of the male die, the male die and the female die below the male die are arranged on a sleeve in a lapping mode through the horn-shaped handles on the side wall of the male die, and the outer diameter of the female die is smaller than the inner.

Furthermore, the number of the ejector rods is three.

Furthermore, the horn-shaped handles are arranged in two groups.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a mould adds auxiliary fixtures's method, the formpiston atress mode when having changed and having opened the mould with the pinch bar, open the in-process of mould after the vulcanization through exerting pressure gently for circular top board, pressure transmits the bed die through the short ejector pin of circular top board, force bed die and formpiston separately, under the effect of gravity, the bed die falls into the sleeve, the bed die has overcome and has opened the formpiston atress inequality that the mould leads to with the pinch bar, the problem that the yield is low, auxiliary fixtures's design, also very big intensity of labour who has alleviateed the operative employee, and the production efficiency is improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances.

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1-5, the mold tool for vulcanizing the corrugated rubber film comprises a male mold 3 and a female mold 5, the male mold 3 and the female mold 5 can be vulcanized to form the corrugated rubber film, the mold tool further comprises a circular upper press plate 1, a plurality of ejector rods 2, a horn-shaped handle 4 and a sleeve 6, the male mold 3 comprises a mold body part and an edge part, a plurality of openings are formed in the edge part at equal intervals, the lower end face of the circular upper press plate 1 is vertically provided with the plurality of ejector rods 2 downwards, the plurality of ejector rods 2 correspond to the openings of the male mold 3 in position, and the plurality of ejector rods 2 penetrate through and extend out of the openings of the male mold 3 and are fixed with the male mold 3; the female die 5 comprises a die body part and an edge part, when the die body part of the female die 5 is tightly matched with the die body of the male die 3, a plurality of ejector rods 2 are tightly attached to the upper end face of the edge part of the female die 5, a plurality of groups of horn-shaped handles 4 are annularly arranged on the side wall of the male die 3, the male die 3 and the female die 5 below the male die are erected on a sleeve 6 through the horn-shaped handles 4 on the side wall of the male die 3, and the outer diameter of the female die 5 is smaller than the inner diameter of the sleeve 6.
