Description
Technical Field
The invention belongs to the technical field of rubber edge covering processing of filter screens, and particularly relates to a die for rubber edge covering processing of filter screens.
Background
The metal filter screen framework is wrapped with rubber, a combined rubber ring is processed, a mounting groove is formed in the rubber ring, the filter screen framework is manually arranged in the groove in the rubber ring through the elasticity of rubber, and the manual assembly efficiency is low.
The rubber wrapping edge and the filter screen framework are vulcanized into a whole by adopting a mold at present, but in the vulcanization, the rubber body is easy to extend to the middle of the filter screen, and the wrapping quality is influenced. Affecting the quality of the seal.
Disclosure of Invention
Aiming at the problems of defects and deficiencies in the prior art, the invention provides the mold for rubber edge covering of the filter screen, the injected material enters the mold cavity uniformly, and the rubber of the edge covering can not extend to the middle of the filter screen framework in the vulcanization process.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a mould is used in processing of borduring of filter screen rubber, includes by lower supreme lower mould, well mould, last mould and the top mould that links up in proper order, the lower mould is equipped with a plurality of type platform, be equipped with on the well mould with the corresponding complex die cavity of type platform, and be equipped with corresponding sealing washer on type platform and the die cavity respectively, it is equipped with and corresponds matched with material cup with the die cavity to go up the mould, be equipped with on the top mould and correspond matched with notes stopper with the material cup, it is equipped with the flow hole of annotating that links to each other with.
Furthermore, the lower die is also provided with a positioning column, a mounting hole and a rubber sealing ring mounting groove.
Furthermore, the middle die, the upper die and the top die are respectively provided with positioning holes which are correspondingly matched with the positioning columns, and the upper die is designed with rubber sealing ring mounting grooves.
Furthermore, the number of the molding tables is nine, and the molding tables are arranged in an array.
The invention has the following beneficial effects: according to the invention, the injected materials uniformly enter the die, and the sealing rings are arranged, so that the injected materials can not extend to the middle of the filter screen framework in the rubber edge-covering vulcanization process, and the qualification rate and the sealing quality of products are improved.

FIG. 1 is a schematic cross-sectional view of a mold platen portion of the present invention;
FIG. 2 is a schematic view of the lower mold structure of the present invention;
FIG. 3 is a schematic view of the mold assembly of the present invention;
FIG. 4 is a schematic structural view of a processed product of the present invention.
Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings.
As shown in the figure, a mould is used in bordure processing of filter screen rubber, include by lower supreme lower mould 1 that links up in proper order, well mould 2, go up mould 3 and top mould 4, lower mould 1 is equipped with a plurality of type platform 11, be equipped with on well mould 2 with the corresponding complex die cavity 21 of type platform 11, and be equipped with corresponding sealing washer 5 on type platform 11 and the die cavity 21 respectively, it is equipped with and corresponds matched with material cup 31 with die cavity 21 to go up mould 3, be equipped with on the top mould 4 and correspond matched with notes stopper 41 with material cup 31, it is equipped with the notes discharge orifice 42 that links to each other with die cavity 21 to annotate stopper 41 below.
Still be equipped with reference column 12 on the lower mould 1 template, reference column 12 is used for installing well mould 2, last mould 3, be equipped with the locating hole that corresponds matched with reference column 12 on well mould 2, last mould 3 and the top mould 4 respectively, be equipped with the reference column on the top mould 4 template equally and be used for installing in well mould, the corresponding locating hole of last mould. The mold is then laid flat in a vulcanization press.
Nine molding beds 11 are just arranged in array, nine work pieces of workable once, and are efficient.
Specifically, before production, the silica gel sealing ring 5 is installed in a groove corresponding to the upper die and the lower die, then the metal filter screen framework 20 is placed on the lower model table, the rubber material is placed in the upper die 31, the middle die plate, the upper die plate and the top die plate are sequentially closed, and then the die is flatly placed in the vulcanizing press. The vulcanizing machine is used for applying pressure to the top die, so that rubber materials in the upper die enter the cavity through the injection hole 42 for vulcanization, and the rubber wrapping edge of the filter screen is formed at one time.
According to the invention, the injected materials uniformly enter the die, and the sealing rings are arranged, so that the injected materials can not extend to the middle of the filter screen framework in the rubber edge-covering vulcanization process, and the product percent of pass is improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. The present invention is not limited to the above-described embodiments, which are described in the specification and illustrated only for illustrating the principle of the present invention, but various changes and modifications may be made within the scope of the present invention as claimed without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
