Single-double-color rubber vacuum hot-pressing forming machine

Abstract

The invention discloses a single-double-color rubber vacuum hot-pressing forming machine comprising an upper base plate and an upper transverse plate, the middle end of the inner surface of the upperbase plate is connected with a middle frame lifting oil cylinder, the right end of the top of the upper base plate is fixedly connected with a middle frame turning plate oil cylinder, and the bottom of the middle frame turning plate oil cylinder is movably connected with a connecting rod; and the left end of the bottom of the upper base plate is connected with the connecting rod through a middle frame turning plate guide rod, the connecting rod is connected with a middle frame, side plates are fixedly connected to the left and right sides of the bottom of the upper transverse plate, a rotatingupper plate is connected with a turning plate, the turning plate is arranged between the two side plates through a rotating shaft, and a turning oil cylinder controls the rotating upper plate to turnwith the rotating shaft as the circle center through an oil pressure system. A vacuum environment required in the shoemaking process can be provided, poor exhaust of shoes is overcome, the shoes areprevented from being burnt, use is safe, color mixing is avoided through manual pouring, combination is stable, compared with a product produced through a common injection foaming forming machine, theforming machine has the advantages that the appearance and color of a product produced by the forming machine are better, the pattern shape is more stereoscopic, meanwhile, the production efficiencyis high, the yield is increased, and the stability is higher.

Description

technical field [0001] The invention relates to the technical field of hot-press forming machines, in particular to a single-color and double-color rubber vacuum hot-press forming machine. Background technique [0002] The traditional thermoforming machine is fixed on the machine table by four columns, a fixed seat is fixed on the top, and a sliding seat can move up and down along the four columns. The hydraulic system controls the sliding seat to align the mold along the four columns. When the mold is opened and closed, the fixed seat is connected with the threaded column to adjust the height of the mold accordingly. However, when the mold is closed, the oil pressure will concentrate the stress on the thread of the column. This problem will lead to unstable mold adjustment in the later stage, and it will take time to replace the column. Labor-intensive, limited by the positions of the fixed upper mold and the movable lower mold, the operator must take the material and clean...

Problems solved by technology

[0002] The traditional thermoforming machine is fixed on the machine table by four columns, a fixed seat is fixed on the top, and a sliding seat can move up and down along the four columns. The hydraulic system controls the sliding seat to align the mold along the four columns. When the mold is opened and closed, the fixed seat is connected with the threaded column to adjust the height of the mold accordingly. However, when the mold is closed, the oil pressure will concentrate the stress on the thread of the column. This problem will lead to unstable mold adjustment in the later stage, and it will take time to replace the column. Labor-intensive, limited by the positions of the fixed upper mold and the movable lower mold, the operator must take the material and clean the mold in the limited space between the upper mold and the lower mold, which is quite inconvenient, and the vulcanization process is not carried out in a vacuum In the environment, the products often have air bubbles and slag inclusions, many defective products, poor stability, etc. For this reason, we propose a single-color rubber vacuum hot-press molding machine
