Problems solved by technology
[0011] In order to solve the problems of "flash" and "bubble" on the shock-absorbing rubber seat that are easy to appear in the existing forming mold after the shock-absorbing rubber seat is demoulded, the present invention provides a kind of mold that can effectively eliminate "flash" and "bubbles" after demoulding. Shock-absorbing rubber seat forming mold with "bubble" phenomenon

Embodiment Construction
[0034] In this embodiment, a molding die for a shock-absorbing rubber seat, the shock-absorbing rubber seat has a stepped rubber seat body 1, and the stepped rubber seat body 1 includes a circular base 2 and a circular seat cap with a diameter smaller than the circular base 2 3 and the connecting neck 4 located between the circular base 2 and the circular seat cap 3, a central through hole 5 is opened in the stepped rubber seat body 1, and the central through hole 5 is a three-dimensional structure composed of three different apertures. Step-type through-holes, the central through-hole 5 is located in the lowermost part with the largest aperture, the middle layer has the smallest aperture, and the uppermost aperture is in the middle;
[0035] In this embodiment, the forming mold includes, from top to bottom, a trough mold 6 for injecting glue and forming the circular seat cap 3, an upper plate mold 7 for forming the connecting neck 4, and a mold for forming the circular base 2....

The invention relates to the field of forming mold manufacturing, in particular to a forming mold of a damping rubber seat. The damping rubber seat is provided with a stepped rubber seat body, whereinthe stepped rubber seat body comprises a round base and a round seat cap with the diameter smaller than that of the round base; a connection neck is positioned between the round base and the round seat cap, and a central through hole is formed in the stepped rubber seat body; and the forming mold sequentially comprises a material groove mold, an upper plate mold, a middle plate mold and a bottomplate mold from top to bottom, the material groove mold is used for injecting glue and forming the round seat cap, the upper plate mold is used for forming the connecting neck, the middle plate mold is used for forming the round base, and the bottom plate mold used for forming the central through hole. According to the forming mold, the phenomena of flash edges" and "bubbles" easily caused by a forming mold of a traditional damping rubber seat are greatly reduced, the yield is greatly improved, the labor cost is saved, the production efficiency is improved, and the forming mold has a high application prospect.
Description
technical field [0001] The invention relates to the field of forming mold manufacturing, in particular to a forming mold for a shock-absorbing rubber seat. Background technique [0002] Shock-absorbing rubber seat is an elastic component for shock-absorbing and reducing vibration and noise. It is often used for vibration isolation and noise control of mechanical equipment such as water pumps, cooling towers, fans, compressors, air-conditioning units, and diesel engines. For this reason, shock-absorbing rubber is required The seat should have good shock-absorbing performance and anti-aging performance. Structurally, the existing shock-absorbing rubber seat usually has a base, and several seat caps are arranged on the base, and a connecting neck is arranged between the base and the seat cap. through hole. [0003] In the prior art, the shock-absorbing rubber seat is processed in a flat vulcanizing machine by using a special forming mold. Since the shock-absorbing rubber seat...
