Gas-blowing demolding mechanism of automobile vent pipe injection mold

Abstract

The invention discloses a gas-blowing demolding mechanism of an automobile vent pipe injection mold. The blowing demolding mechanism comprises a main body, an anti-backflow device and a device frame,wherein a first clamping block is movably connected to the interior of the main body, a pushing rod is fixedly mounted on the surface of the first clamping block, and a conveying tube is fixedly mounted in the first clamping block; a connecting tube is fixedly mounted at the bottom of the conveying tube, a circulating tube is fixedly mounted at the top of the conveying tube, and a sprue gate is movably connected to the top of the first clamping block. According to the injection mold disclosed by the invention, through the arrangement of the connecting rod, the first spring and the drive rod, after injection molding of the mold is completed, the drive rod drives a second clamping block to move to separate an injection-molded tube from the second clamping block; and through the arrangement of the anti-backflow device, cooling liquid enters the conveying tube through the connecting tube to cool the injection-molded tube, so that the tube can be quickly separated from the first clamping block, and the transmission tube can be filled with cooling liquid.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an air blowing demoulding mechanism of an injection mold for an automobile ventilation pipe. Background technique [0002] Automobile ventilation pipes cannot be bent by tools during production, but can only be injection molded. The method of injection molding in daily life makes the production of automobile ventilation pipes faster, but there are still certain problems when the production is demoulded. exist, the specific issues are as follows: [0003] 1. During injection molding production, the heat inside the mold cannot be dissipated in time. When the pipe is removed, the surface will be torn and damaged, which will affect the use of the pipe, lead to the scrapping of the pipe, and affect the production progress; [0004] 2. During injection molding production, the mold will adhere to the mold groove on the surface of the clamp block after injection molding, and can...

Problems solved by technology

[0003] 1. During injection molding production, the heat inside the mold cannot be dissipated in time. When the pipe is removed, the surface will be torn and damaged, which will affect the use of the pipe, lead to the scrapping of the pipe, and affect the production progress;

[0004] 2. During injection molding production, the mold will adhere to the mold groove on the surface of the clamp block after injection molding, and cannot fall off by itself. It needs to be removed manually, which delays the production progress and poses a safety hazard
