Problems solved by technology

After the heating plate is heated, it is directly in contact with the mold for heating, which belongs to the solid heat conduction mode between the plates. This heat conduction mode has low heat conduction efficiency, serious heat loss, and uneven heat distribution, which affects the secondary foaming efficiency and the product. Uneven foaming
The plate-to-plate cooling process has poor thermal conductivity, and the heat is difficult to dissipate. The heat distribution inside the mold is uneven, and it is difficult to achieve the purpose of rapid cooling of the mold, thus affecting the work efficiency of the secondary foaming

Abstract

The invention relates to a steaming type secondary foaming insole machine in the field of foaming equipment. The steaming type secondary foaming insole machine comprises a main machine frame and a foaming mechanism arranged on the main machine frame, wherein the main machine frame comprises a lower support and an upper support, the upper support comprises a supporting top plate and a lateral supporting plate, a hollow cylindrical heat insulation cover is fixedly arranged on the bottom surface of the supporting top plate, a supporting bottom plate is arranged on the top surface of the lower support, a hydraulic cylinder is vertically mounted on the supporting bottom plate, a piston disc is connected to a telescopic rod of the hydraulic cylinder, the top surface of the heat insulation coveris connected with a feeding pipe body communicating with the interior of a working cavity, and the bottom of the piston disc is connected with a discharging pipe set communicating with the interior ofthe working cavity. The whole secondary foaming process is simple in action, and the foaming process is completely completed in the working cavity; steam is adopted as a heating medium to heat a whole finished product mold, so that a traditional heating mode is subverted; and a novel heat conduction mode is adopted so that the steam can make direct contact with the mold, the heat conduction efficiency is higher, the heat conduction is more uniform, and the efficiency of whole secondary foaming can be improved.

Description

technical field [0001] The invention relates to the field of foaming equipment, in particular to a steam-type secondary foaming midsole machine. Background technique [0002] EVA material is currently widely used in the midsole of footwear because of its advantages such as light material, biodegradable, reusable, and no harm to the environment when burned. The production of present midsole is mainly by putting granular EVA material in the die cavity of the lower mould, and when the upper mold is pressed down, the upper and lower molds are heated simultaneously, and the granular EVA material is heated in the mould. After foam molding, take out the foam-molded shoe midsoles from the upper and lower molds, and the shoe midsoles will present the processed shape. The section of the shape presents a narrow bottom and wide top shape. However, since the sole structure of people is wide at the bottom and narrow at the top, that is, the cross-section of the sole of the foot is the wi...
