Detailed description of the invention
Fig. 1 be the utility model proposes a kind of O-ring torn edges mold structural schematic diagram.
Specific embodiment
As shown in FIG. 1, FIG. 1 is the utility model proposes a kind of O-ring torn edges mold structural schematic diagram.
Referring to Fig.1, the utility model proposes a kind of O-ring torn edges mold, comprising: cope plate 1, middle template 2 and under
Template 3；
1 bottom of cope plate is equipped with multiple modules 4, and arranged for interval between two neighboring module 4, each 4 bottom of module is equipped with
First die cavity, be equipped in the middle part of middle template 2 it is multiple run through die cavity, each minimum diameter through die cavity is greater than corresponding module 4 most
Big outer diameter, it is two neighboring it is described the torn edges slot 6 to communicate with each other is equipped between die cavity, be equipped with multiple second at the top of lower template 3
Die cavity, is equipped with mold core 5 in the middle part of second die cavity, and each first die cavity runs through die cavity and second die cavity is corresponding sets with one
It sets and type chamber is collectively formed in three.
In the specific work process of the torn edges mold of the O-ring of the present embodiment, cope plate, middle template, lower template are successively set
Molding is set, so that the first die cavity, through die cavity, the second die cavity type chamber is collectively formed, by being moulded in the intracavitary molding O-ring of type,
Be opened after molding, move down lower template, mold core is extracted out from type chamber, then moves up middle template so that module by O-ring to
Lower release, while four sides in torn edges slot being torn from O-ring, realize that synchronous torn edges demoulding, last middle template decline reset,
Torn edges in torn edges slot is taken out.
In the present embodiment, the torn edges mold of the O-ring proposed, cope plate bottom is equipped with multiple modules, two neighboring
