Gear box built-in plastic part high-pressure sheath forming die

Abstract

The invention provides a gear box built-in plastic part high-pressure sheath forming die. The gear box built-in plastic part high-pressure sheath forming die comprises an upper die body, a die setup middle frame and a lower die body. A die cavity is formed in the die setup middle frame. A plurality of half blocks are arranged in the die cavity. The side surface and the top surface of each half block are each provided with a plurality of wear-resistant blocks. The die setup middle frame comprises a front formwork plate, and a plurality of gear boxes are arranged at the front end of the front formwork plate. A plurality of positioning guide columns are arranged in the lower die body. A plurality of cores are also arranged in the lower die body. The gear box built-in plastic part high-pressure sheath forming die is simple in structure and convenient to use, through the design of the wear-resistant blocks, the cores, the positioning guide columns and the two-way gear boxes, the wear resistance and stability of the die are improved, and the service life of the die is prolonged; and meanwhile, due to the overall design of the die, the product can be quickly demolded, and burrs do not need to be removed after demolding, so that the production efficiency is further improved, the foreign matter risk is greatly reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of high-voltage sheath moulds, in particular to a high-voltage sheath molding mold for a built-in plastic part of a gear box. Background technique [0002] The high-voltage sheath of the built-in plastic part of the gearbox is usually processed by mold injection. When the high-voltage sheath is produced, the production efficiency is low, the stability of the mold is poor, and the service life is short. These have always been two major problems that enterprises need to continuously improve. [0003] Although the existing high-voltage sheath forming molds can solve the above two problems to a certain extent, for example, it is mentioned in a Chinese patent on a vertical built-in high-voltage sheath mold for plastic parts (application number: CN201920523729.5), through the Huff block, The mutual cooperation of the balance baffle, tie rod, oil cylinder and other structures can make the cylinder use the pull rod to drive t...
