Foaming agent injecting device of shoe sole foaming machine

Abstract

The invention belongs to the technical field of shoe manufacturing, and provides a foaming agent injecting device of a shoe sole foaming machine. The agent injecting device comprises a frame (1), a nozzle (8), and a plate I (3) and a plate II (4) for driving the nozzle to move, wherein the nozzle (8) is located on a nozzle fixed mount (7); the nozzle fixed mount (7) is connected with the plate II (4); the plate II (4) is located on a slide rail II (6) of the plate I (1) and arranged vertically to the plate I (3); a guide wheel (9) arranged on one end of the plate II (4) is located in a mold hole (16) of a mold board (2) and elastically props against the wall of the mold hole of the mold board; and the guide wheel (9) is driven by the plate I (3) and the plate II (4) to perform horizontal and vertical composite motions along the motion trail limited by the inner wall of the mold hole of the mold board (2). By the foaming agent injecting device, the foaming agent nozzle can inject a foaming agent to a bottom mold along the motion trail limited by the mold hole of the mold board, so that the production efficiency and the production quality can be improved, and the waste of materials can be reduced to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of shoemaking, and in particular relates to a foaming agent injection device for a foaming shoe machine. Background technique [0002] In the shoemaking process, the shoe mold has a shoe last and a bottom mold; it is necessary to inject a foaming agent into the bottom mold; while the existing shoemaking process uses manual operation to inject the foaming agent, the time for injecting the foaming agent is different. The flow rate of foaming agent is relatively difficult to control; especially the uniformity of foaming agent injection is difficult to control, which directly affects the quality of shoemaking and causes waste of foaming materials. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a foaming agent injection device for a foaming shoe machine. [0004] The present invention adopts following technical scheme for accomplishing abo...
