Abstract

The invention discloses a sleeve rubber mold without trimming. The rubber mold comprises an upper mold plate, a runner plate is arranged on the top of the upper mold plate, the bottom of the upper mold plate is connected to a lower mold plate through a middle mold plate, an upper groove is formed in the bottom of the upper mold plate, a lower groove is formed in the bottom of the lower mold plate,an upper mold insert and a lower mold insert are separately arranged in the upper groove and the lower groove, a cavity for a sleeve product is formed among the upper mold insert, the lower mold insert and the middle mold plate, an injection hole is formed in the upper mold plate, the top of the injection hole communicates to the runner plate, and the injection hole penetrates to the cavity fromthe top of the upper mold plate. The rubber mold is characterized in that an exhausting system is arranged on the upper mold plate, and the exhausting system penetrates to the cavity from the top of the upper mold plate. The rubber mold is suitable for a shock absorbing sleeve product of an automobile chassis, solves the problem of trimming the shock absorbing sleeve product in the rubber mold, and ensures that no flashes are available after the product is demolded, so that the rubber material and labor are saved, and the utilization ratio and the production efficiency of the rubber material are improved.

Description

technical field [0001] The invention relates to a rubber mold with no flash structure for the bushing, in particular to a mold suitable for shock absorbing bushing products of automobile chassis, belonging to the technical field of rubber molds. Background technique [0002] In the production of rubber molds, due to the good overflow performance of the rubber material, the internal pressure of the mold cavity is greater than the external pressure during the exhaust and pressure relief process, resulting in the overflow of the rubber material in the mold cavity to the outside of the mold cavity and flashing, resulting in Rubber waste and labor loss. Contents of the invention [0003] The technical problem to be solved by the invention is to solve the problem of flashing of the mold due to exhaust. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is to provide a rubber mold with a bushing without flash struct...
