Integral inlaying type ventilation steel die

Abstract

The invention discloses an integral inlaying type ventilation steel die. The integral inlaying type ventilation steel die comprises an inlaying base upper die body, a ventilation steel upper die body, a ventilation steel lower die body, an inlaying base lower die body, changing bolt holes, a temperature sensor installing hole and ventilation holes. According to the integral inlaying type ventilation steel die, an inlaying structure of an inlaying base and ventilation steel is adopted, a die mold cavity is formed through combination of the ventilation steel upper die body and the ventilation steel lower die body, and the die has good breathability. Meanwhile, a machined product has good surface quality. The ventilation steel upper die body and the ventilation steel lower die body of the die only account for a very small part of the whole die, and most of the rest of die bases are made of cheap metal materials (such as an aluminum alloy, a magnesium alloy and die steel), and the die cost is greatly reduced. To guarantee good exhausting performance of the die, a sinking part with the height of 2 mm-5 mm is machined on the inlaying base upper die body, and a sinking part with the height of 2 mm-5 mm is machined on the inlaying base lower die body; and in the effective exhausting area of the sinking parts, the 6-18 ventilation holes are distributed, and to guarantee good heat conduction performance and strength, the size of the ventilation holes is not suitable for being too large.

Description

technical field [0001] The invention belongs to the field of moulds, and in particular relates to an integral mosaic type steam-permeable steel mould. Background technique [0002] Plastic products have greatly accelerated the development of human civilization and high technology, and provided many conveniences for human life. A considerable part of plastic products are manufactured using molds based on the principle of hot pressing and exhaust steam. Especially with the emergence of degradable biomass material products that use plant fibers as reinforcements, the traditional hot-pressing exhaust steam molding molds have exposed many shortcomings when pressing these products, such as the conflict between exhaust steam and hot pressing, exhaust steam The contradiction between good effect and surface quality, easy clogging, serious mold sticking phenomenon, long molding time, low heat transfer efficiency, uneven temperature distribution and difficult mold cleaning, etc. The ...
