Glass hot bending mold and its manufacturing method and application

Abstract

The invention discloses a glass hot-bending die as well as a manufacturing method and application of the glass hot-bending die, belonging to the technical field of solar energy utilization. The glass hot-bending die comprises a main body and a frame-shaped glass edge hot-bending part, wherein the main body has a plurality of through holes which pass through the upper and lower surfaces of the main body; the frame-shaped glass edge hot-bending part is connected with the main body; a glass forming surface is formed by the upper surface of the frame-shaped glass edge hot-bending part together with the upper surface of the main body. According to the glass hot-bending die, by forming the through holes in the main body part of the glass hot-bending die, materials used by the glass hot-bending die are reduced, the die production cost is lowered, the heat that the die absorbs is reduced, the uniform glass heating and forming in the hot-bending process are facilitated, the radiation of the heat of the die is facilitated, and both the service life of the die is prolonged and the forming precision of glass is ensured; due to the existence of the through holes, the hot-bending die is good in heat circulation in the hot-bending process, a plurality pieces of glass can be hot-bent simultaneously, the production efficiency is greatly improved, and due to the arrangement of the through holes, the weight of the die is reduced, and the die can be conveniently hoisted and transported.

Description

technical field [0001] The invention relates to a glass hot-bending mold and its manufacturing method and application, belonging to the technical field of solar energy utilization, in particular to a glass hot-bending mold used for a reflective part of a solar heat utilization system. Background technique [0002] Solar collectors are the key components of various solar heat utilization systems. Whether it is solar water heaters, solar cookers, active solar houses, solar greenhouses or solar drying, solar industrial heating, solar thermal power generation, etc., solar collectors are inseparable, and solar collectors are used as the power or core components of the system. . [0003] Solar collectors use reflectors to gather sunlight. At present, according to the different types of reflectors, solar collectors are divided into trough collectors, tower collectors, dish collectors, and Fresnel collectors. device etc. The reflector of a solar collector is generally composed of...

AI Technical Summary

Problems solved by technology

[0005] Existing glass hot-bending molds are large in size and weight, and the production cost of the mold is high; the glass hot-bending process needs to be carried out at high temperature, and the mold absorbs a large amount of heat at high temperature, and is prone to deformation. It cannot be used repeatedly and the glass backplane cannot be guaranteed. The molding accuracy cannot meet the requirements of the focal length and spot size of the mirror design, resulting in the loss of concentrating energy; the mold temperature rises and cools slowly, and the molding process of the glass backplane takes a long time and the production efficiency is low.
