Thermoforming mold internal purging system

Abstract

The invention discloses a blowing system in a thermal forming mold. The system comprises a gas source for generating compressed gas and a gas conveying pipe for conveying the compressed gas. The gas conveying pipe is connected to the thermal forming mold and the gas outlet end of the gas conveying pipe faces a cavity of the thermal forming mold so as to spray the compressed gas to the surface of the cavity. According to the blowing system in the thermal forming mold disclosed by the invention, the gas conveying pipe is additionally arranged on the thermal forming mold, the compressed gas is conveyed to the surface of the cavity of the thermal forming mold through the gas conveying pipe, and scales on the surface of the cavity are blown with a fixed mechanical structure, that is, a blowingfunction is integrated on the mold to replace manual online blowing, so that the surface of the mold is conveniently blown, accumulation of the scales is prevented effectively, the blowing efficiencyis increased, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the field of production and processing of mechanical parts, in particular to a purging system in a thermoforming mold. Background technique [0002] During the forming process of thermoformed parts, iron scale will inevitably be produced on the surface of the part. As the number of punches increases, the scale will gradually accumulate on the surface of the mold. The accumulation of scale will cause crushing on the surface of the part and accelerate the wear of the mold surface. In order to reduce the accumulation of oxide scale on the surface of the mold, manual online purging is now used to increase the frequency and cost of mold maintenance, and the work content and labor intensity of operators will increase correspondingly when purging is performed every time. [0003] Therefore, in order to solve the above problems, a purge system in the thermoforming mold is needed. The purge function is integrated on the mold to facilita...

[0002] During the forming process of thermoformed parts, iron scale will inevitably be produced on the surface of the part. With the increase of the number of strokes, the scale will gradually accumulate on the surface of the mold. The accumulation of scale will cause crushing on the surface of the part and accelerate the wear of the mold surface.

In order to reduce the accumulation of oxide scale on the surface of the mold, manual on-line purging is now used to increase the frequency and cost of mold maintenance, and the work content and labor intensity of operators will increase accordingly
