Abstract

The invention provides a rubber elastic joint injection mold which comprises an upper mold body, a lower mold body and a middle mold body. The upper mold body comprises a top plate located at the top of the upper mold body, an upper core mold fixing plate arranged on the lower portion of the top plate, upper core molds fixedly arranged on the upper core mold fixing plate, an upper push plate arranged on the lower portion of the upper core mold fixing plate and a limit piece capable of limiting the upper core mold fixing plate to move vertically. The lower mold body comprises a base plate located at the bottom and lower core molds fixedly arranged on the base plate. The middle mold body comprises a lower push plate arranged above the base plate, clamping blocks which are arranged between the adjacent lower core molds correspondingly and are fixedly arranged at the top of the lower push plate, and slide blocks capable of horizontally sliding along the top of the lower push plate. By adoption of the rubber elastic joint injection mold, vulcanized rubber elastic joints can be effectively taken out of the mold, and meanwhile, requirements of large-batch production of the rubber elastic joints can be met.

Description

technical field [0001] The invention belongs to the technical field of molds, in particular to a rubber elastic joint injection mold. Background technique [0002] Rubber elastic joints are widely used in rail vehicle bogies to play the functions of vibration reduction and vibration isolation, which play an important role in the safety, comfort and stability of vehicle operation. Referring to Figure 1(a), Figure 1(b) and Figure 1(c), the rubber elastic node is composed of a mandrel 19, a jacket 20 and a rubber 21, wherein the mandrel 19, the jacket 20 and the rubber 21 are bonded by thermal vulcanization Vulcanized together, the rubber type 21 faces are separated with two through holes. [0003] The characteristics of the rubber elastic nodes shown in Fig. 1(a), Fig. 1(b) and Fig. 1(c) are: (1) Since the transition zone between the mandrel 19 and the rubber 21 at the end is straight, therefore, in the high-pressure injection During the sizing process, the sizing material w...
