Thermal forming insert for stamping die

Abstract

The invention discloses a thermoforming insert for a stamping die, which comprises a positioning ring, a limiting groove, a sealing rubber ring, a fixing screw hole, a heating rod and a heat insulation plate, a limiting groove is arranged under the positioning ring, and the There is a fixed screw hole on the right side of the sealing rubber ring, and a heat insulation plate is arranged under the heating rod. The structure of the present invention is scientific and reasonable, and it is safe and convenient to use. To prevent the offset of the insert when stamping the mold; a sealing rubber ring is provided to prevent the gas from entering, without leakage, and to make the gas distribution inside the mold even; a fixing screw hole is provided to facilitate the fixing of the mold and the connection with other objects The connection; the heating rod is provided to make the inside of the mold be heated more uniformly, and the hardness of the product is improved; the heat shield is provided to shorten the thermoforming time and solve the problem of uneven internal stress of the product.

Description

technical field [0001] The invention relates to the technical field of thermoforming inserts, in particular to a thermoforming insert for stamping dies. Background technique [0002] With the development of industry, people's requirements for mold inserts are also increasing, especially for the fixing of mold inserts and the process of cooling and tempering. However, most of the mold inserts currently on the market Not only the cost is high, but also its stability is poor. As a result, when stamping, the center of the mold often deviates, causing burrs on the edge of the product, thereby reducing the production quality of the product and increasing the economic cost, and the existing mold exists for cooling. During air cooling and tempering, due to the uneven entry of cooling air, the internal stress of the mold is uneven, which reduces the hardness of the product and is easy to be brittle during the collision process. At the same time, the outer ring of the existing mold do...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a thermoforming insert for a stamping die, which can effectively solve the problem of poor stability in the above-mentioned background technology, which often causes the center of the mold to deviate during stamping, causing burrs on the edge of the product, thereby reducing product production. The quality increases the economic cost, the uneven internal stress of the mold reduces the hardness of the product, and it is easy to be brittle during the collision process. There is no sealing equipment, which leads to excessive loss of compressed air, cooling air, hot air, etc., which affects the thermoforming module. Poor quality, poor heat insulation effect, easy to dissipate the heat inside the mold, prolong the molding time of the mold, etc.
