Abstract

The invention provides an externally-convex core applicable to a vulcanized rubber product axially provided with a through hole. An internally-concave part extending to the direction deviating from the axial direction of the through hole is arranged in the through hole, the externally-convex core comprises a mandrel and a pellet assembly which is arranged on the surface facing to the rubber product, of the mandrel, the pellet assembly comprises a plurality of pellets arrayed in sequence, and the neighboring pellets are detachably connected; a plurality of fixing slots are axially arranged in the mandrel, each pellet is provided with fixing steps clamped with the fixing slots to fixedly connect the pellet assembly and the mandrel, and an externally-convex part matched with the internally-concave part is arranged in the surface facing to the rubber product, of the pellet assembly. The invention further provides a vulcanized mould provided with the above-mentioned externally-convex core. By the arrangement, separation of the core and the rubber product is facilitated, and vulcanization efficiency and product quality are improved.

Description

technical field [0001] The invention belongs to the technical field of rubber vulcanization, and in particular relates to a convex core and a vulcanization mold. Background technique [0002] see figure 1 , the vulcanization of the rubber product 2 is realized by a vulcanization mold. When the rubber product 2 is provided with a through hole 21 in the axial direction, the vulcanization mold is axially provided with a core at a position corresponding to the through hole 21 of the rubber product 2, and the core is axially installed in the through hole 21. In the hole, to realize the vulcanization of the rubber product 2, after the vulcanization is completed, the core can be removed from the through hole. As the structure of rubber products becomes increasingly complex, the through hole 21 of the rubber product 2 is provided with an inner concave portion 22 extending away from the axial direction of the through hole 21, and the core also chooses an outwardly convex core, that ...
