Thermal reshaping compression die jig

Abstract

The invention discloses a thermal reshaping compression die jig which comprises a die frame, an upper pad plate, an upper die plate, a lower pad plate, a lower die plate, an upper heating module, a lower heating module, a driving device and a control system. The lower pad plate is fixed to the lower side face of the die frame, the lower heating module is fixedly installed on the lower pad plate, the lower die plate is fixedly installed on the upper side of the lower pad plate, the upper pad plate can be slidingly installed on the upper side of the die frame in the longitudinal direction, the upper heating module is installed on the upper pad plate, the upper die plate is fixedly installed on the lower side of the upper pad plate, an upper die cavity is formed in the lower side surface of the upper die plate, a lower die cavity is formed in the upper side surface of the lower die plate, a silica gel layer is arranged on the surface of the upper die cavity of the upper die plate, the silica gel layer and the lower die cavity can jointly form a cavity structure matched with a product to be reshaped and compressed in appearance, and the control system controls the driving device to drive the upper pad plate to slide longitudinally. The thermal reshaping compression die jig is conductive to improvement of product reshaping precision, meanwhile avoids product surface compression damage and ensures product quality.

Description

technical field [0001] The invention relates to an auxiliary jig, in particular to a jig for a hot-pressing mold. Background technique [0002] After the die-casting molding is formed, it will be deformed to varying degrees due to rapid cooling, material problems, and structural problems of the product itself. However, the size of the product itself has high requirements, and some of it is an appearance surface. The product deformation problem must be solved by reshaping the product later. Shaping accuracy has always been a difficult problem to solve. [0003] The current thermal shaping method is to use thermoplastic deformation to shape, and the shaping jig generally has an oven jig, and the upper and lower templates are heated briefly to press the jig. The oven takes a long time and costs high, and the short-term heating of the upper and lower template pressing fixtures is efficient, but the effect of traditional fixtures is not obvious. Traditional hot pressing fixture...

AI Technical Summary

Problems solved by technology

The oven takes a long time and costs high, and the short-term heating of the upper and lower template pressing fixtures is efficient, but the effect of traditional fixtures is not obvious

Traditional hot pressing fixtures are divided into upper and lower plates. At present, for aluminum-magnesium alloy castings, metal fixtures are mostly used. Most of them are steel or aluminum materials. The shaping effect is not obvious, and it is easy to crush the surface of the product, causing Product secondary damage
