TECHNICAL FIELD
The present disclosure relates to technical field of rubber molds, and more particularly, to a rubber injection mold.
BACKGROUND
The production process of conventional rubber mold is as follows: a bottom mold is cast and machined by planning and milling; the manual mold assembly is completed; cut-off knives are utilized to cut materials by a bottom plant according to the shape of a bottom design of a single mold body, and the materials are put into a mold manually for hot press molding; and then the mold is trimmed and packaged by a finishing group. Herein, the process is troublesome, the productivity is low and the production cost is high.

The present disclosure aims to provide a rubber injection mold so as to solve the problems that the existing process is troublesome, the productivity is low and the production cost is high in the related art.
To this end, the following technical solutions are provided by the present disclosure: a rubber injection mold, including a binary form-stripping mold; the binary form-stripping mold consists of an upper mold and a bottom mold; the upper mold and the bottom mold are movably connected to one another via a guide post; the guide post is welded on the bottom mold; side rails are further respectively arranged at two ends of the upper mold and the bottom mold; upper mold handles are fixedly mounted in the side rails of the upper mold; an end of the upper mold handles is fixed to inner walls of the side rails, and other end of the upper mold handles is extended out of an external portion of the upper mold; front and rear rails are respectively, fixedly mounted on a lower surface of the upper mold and an upper surface of the bottom mold; the front and rear rails are fitted with each other; finished areas are further respectively arranged on a middle portion of the lower surface of the upper mold and the upper surface of the bottom mold; edge-tearing grooves are formed at a periphery of the finished area, surrounding the entire finished area; a sidewall flash groove is further formed on an outer wall at one side of the binary form-stripping mold; an inward of the sidewall flash groove is connected to an upper mold flow channel which is formed on an outer wall at one side of the upper mold.
As a further solution of the present disclosure, a sidewall edge-tearing groove is further formed on an outer wall joint of the bottom mold, adjoining the upper mold.
As a further solution of the present disclosure, lower-mold-locking briquettings are further respectively, fixedly mounted at two ends of the bottom mold.
As a further solution of the present disclosure, a tapered feeding hole is further formed on an upper surface of the upper mold, and connected to the finished areas.
Compared to the prior art, the present disclosure has the following beneficial effects.
According to the rubber injection mold of the present disclosure, the mold is made of steel and all components thereof are formed by reverse molding, so compared to the previous A3 iron, it is more precise and durable. Compared to the conventional mold that needs to utilize the cut-off knives one by one to cut the materials and needs manual displacement and hot press molding, the present injection manner is an automatic feeding production, so the feeding amount can be accurately controlled, and the material waste and the labor are reduced; and for a finished product after being molded by hot press molding and then being demolded, the burrs can be directly torn down by hand and thus the required outfits of the finishing group are reduced.
