Abstract
The invention provides a top rubber sulfuration die, which can solve the problems of thick edge of top rubber and inconvenience of artificial removal. The top rubber sulfuration die comprises an upper die, a lower die, a die core arranged on the lower die by passing through, an annular inner glue-spilling groove and an outer glue-spilling groove are arranged on a parting surface of the upper die and the lower die, and an annular channel is arranged between the inner glue-spilling groove and the outer glue-spilling groove. By employing a double-flash groove structure, during a sulfuration injection process, a superfluous rubber compound is introduced in the glue-spilling groove, residual rubber compound is introduced in the outer glue-spilling groove, due to effect of two glue-spilling grooves, the edge of the product is thin, edge can be torn slightly, operator intensity is greatly mitigated, work efficiency is increased, the edge thickness between the glue-spilling grooves can be increased by arranging the annular channel, and fracture can be prevented.
Description
Technical field
The present invention relates to a kind of top glue sulfurizing mould.
Background technology
Current, enter average family with doing automobile product, popularizing with popular of automobile, also promotes the development of automobile downstream industry, wherein pushes up glue also fast development.In the production of top glue, the vulcanization of rubber is a wherein important ring, and it is related to the performance of whole product, quality.And sulfurizing mould is core in whole sulfuration process and key.In sulfuration process, because the mobility of rubber is fine, have circle burr on goods limit after sulfuration, traditional way is at sulfurizing mould die cavity periphery processing one circle flash groove, allows unnecessary sizing material overflow in groove, by the unnecessary waste material that manually prunes away after goods take out, its shortcoming is that sizing material weight is difficult to control, and causes burr thicker, manually prunes difficulty, workload is large, and cost of labor is high.
Summary of the invention
The invention provides a kind of top glue sulfurizing mould, be intended to solve the burr pushing up glue in prior art too thick, the problem that artificial removal is cumbersome.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of top glue sulfurizing mould, comprise upper die and lower die, the core rod be located on counterdie, the die joint of described patrix and counterdie is provided with the interior excessive glue groove of annular and excessive glue groove, is provided with circular passage between interior excessive glue groove and excessive glue groove.
Further, also comprise and cut ring for what cut burr, cut ring lower end and be provided with blade, described in cut ring longitudinal section be wedge shape.Be convenient to cut burr.
Further, described interior excessive glue groove is arranged on patrix, the longitudinal section of described interior excessive glue groove be up-small and down-big and triangle.Be convenient to hand and tear burr, and be convenient to heat radiation, make sizing material rapid solidification.
Further, described excessive glue groove is arranged on counterdie, and the longitudinal section of described excessive glue groove is up big and down small triangle.Be convenient to hand and tear burr, and be convenient to heat radiation, make sizing material rapid solidification.
Further, described interior excessive glue groove is made up of the upper cannelure be arranged on patrix and the lower cannelure be arranged on counterdie, and the longitudinal section of described upper cannelure is up-small and down-big triangle, and the longitudinal section of described lower cannelure is up big and down small triangle; The structure of described excessive glue groove is identical with the structure of interior excessive glue groove; Be convenient to tear burr with hand.
Compared with prior art advantage of the present invention is: the present invention adopts two flash groove structure, in sulfuration injection process, unnecessary sizing material is introduced in interior excessive glue groove, if also have unnecessary sizing material will enter in excessive glue groove, the effect of glue groove because twice are overflow, the burr of goods are thinner, only need neat and tidy once tearing gently after taking out, significantly reduce the intensity of operator, add operating efficiency; Arrange circular passage can increase twice and to overflow the thickness of burr between glue groove, prevent fracture.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention in embodiment one;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the structural representation cutting ring in the present invention;
Fig. 4 is interior glue groove and the excessive glue groove structural representation of overflowing in embodiment two.
Detailed description of the invention
Embodiment one:
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of top glue sulfurizing mould, comprise patrix 2, counterdie 3, the core rod 4 be located on counterdie 3, described patrix 2 is provided with the interior excessive glue groove 1 of annular and excessive glue groove 7 with the die joint of counterdie 3, is provided with circular passage 5 between interior excessive glue groove 1 and excessive glue groove 7.Also comprise and cut ring 6 for what cut burr, cut ring 6 lower end and be provided with blade, described in cut ring 6 longitudinal section be wedge shape.Described interior excessive glue groove 1 is arranged on patrix 2, the longitudinal section of described interior excessive glue groove 1 be up-small and down-big and triangle.Described excessive glue groove 7 is arranged on counterdie 3, and the longitudinal section of described excessive glue groove 7 is up big and down small triangle.
During use, unnecessary sizing material enters interior excessive glue groove 1, circular passage 5 and excessive glue groove 7 successively, when after formed product on patrix 2 with the die joint of counterdie 3, take off patrix 2, will cut ring set and be connected on product, blade is pressed in the junction of burr and product, burr are excised, then takes out workpiece; Because burr are thinner, after also product can being taken out, tear burr with hand.
Embodiment two:
Consult Fig. 4, be with the difference of embodiment one: described interior excessive glue groove 1 is made up of the upper cannelure be arranged on patrix 2 and the lower cannelure be arranged on counterdie 3, the longitudinal section of described upper cannelure is up-small and down-big triangle, and the longitudinal section of described lower cannelure is up big and down small triangle; The structure of described excessive glue groove 7 is identical with the structure of interior excessive glue groove 1., unnecessary sizing material enters interior excessive glue groove 1, circular passage 5 and excessive glue groove 7 successively on patrix 2 with the die joint of counterdie 3, when after formed product, takes out product, tears burr with hand; Because burr are thinner, be convenient to tear.
The present invention adopts two flash groove structure, in sulfuration injection process, unnecessary sizing material is introduced in interior excessive glue groove, if also have unnecessary sizing material will enter in excessive glue groove, the effect of glue groove because twice are overflow, the burr of goods are thinner, only need neat and tidy once tearing gently after taking out, significantly reduce the intensity of operator, add operating efficiency; Arrange circular passage can increase twice and to overflow the thickness of burr between glue groove, prevent fracture.
The foregoing is only specific embodiments of the invention, but technical characteristic of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
