Rubber shoe sole forming mold with steam circulation extrusion function

Abstract

The invention discloses a rubber shoe sole forming mold with a steam circulation extrusion function, and relates to the technical field of rubber shoe sole production. The rubber sole forming mold with the steam circulation extrusion function comprises a workbench, a mold set is arranged on the upper side wall of the workbench, the mold set comprises a lower mold and an upper mold rotationally connected to the side wall of the lower mold through a hinge, and handles are arranged on the side walls, away from the hinge, of the mold set; and steam hole channels which are arranged in a bending and circulating manner are formed in the mold groups. Circulating extrusion pressing can be carried out while high-temperature steam heats the mold set, the integration degree is higher, use is more convenient, meanwhile, the energy utilization rate is higher, heat waste is avoided, an oil press does not need to be used, the manufacturing cost is reduced, meanwhile, gas in the mold can be conveniently exhausted, the pit defect of a shoe sole is avoided, the production quality is improved, and the production cost is reduced. And in addition, cooling of the mold set is accelerated, and the cooling forming speed of the mold set is increased.

Description

technical field [0001] The invention relates to the technical field of rubber shoe sole production, in particular to a rubber shoe sole molding die with steam cycle extrusion function. Background technique [0002] The rubber sole refers to the sole made of rubber. The rubber sole material can be roughly divided into natural rubber or artificial synthetic rubber. The most important process in the production process of rubber soles is the sole compaction and shaping. Now the rubber soles on the market are used for production. The sole shaping machine is to put the rubber material into the sole mold, and then push the mold into the hydraulic press to shape the sole. After the shaping is completed, the mold is pulled out from the compacting plate, and the mold is opened to take out the sole to complete the shaping of the sole. processing.

Problems solved by technology

[0003] However, the existing hydraulic press realizes processing and molding by driving the oil cylinder to press the sole mold and heat the sole mold. The heating is completed by the heating mold frame installed on the rubber sole hydraulic press. The current heating mold frame uses heat-conducting oil or steam For heating, it is necessary to install an oil guide or steam guide pipe on the hydraulic press, which needs to be used in combination with the hydraulic press, which is very inconvenient and makes the manufacturing cost higher. At the same time, high-temperature steam is only used for heating, which is easy to cause energy waste. Larger, the gas is not easy to discharge, and it is easy to make pits appear on the sole
