Glass molding press

Abstract

The invention relates to the technical field of glass production equipment, and provides a glass molding press which comprises a fixing plate, an upper mold base, an upper mold core and a lower mold core, the upper mold base is installed on the upper surface of the fixing plate, the upper mold core is installed on the inner top of the upper mold base, the lower mold core is located between the upper mold core and the fixing plate, and the lower mold base is vertically and slidably assembled at the bottom of the fixing plate; a lower die sealing column is fixed to the top of the lower die base and penetrates through the fixing plate, the lower die core is installed at the top of the lower die sealing column, and a lifting device driving the lower die base to ascend and descend freely is arranged at the bottom of the lower die base. A grating ruler displacement sensor is arranged on one side of the lower die base, a pressure sensor is further arranged between the bottom of the lower die base and the top of the lifting device, and the grating ruler displacement sensor and the pressure sensor are both electrically connected to a control system of the glass molding press. According to the glass molding press provided by the invention, through two detection means of high-precision pressure control and high-precision position control, the product rejection rate is reduced, and the production cost is saved.

Description

technical field [0001] The application belongs to the technical field of glass production equipment, and more specifically relates to a glass molding machine. Background technique [0002] Glass molding machine is a machine equipment in the glass manufacturing industry and glass machinery industry. It belongs to the glass forming section in the glass manufacturing process. [0003] At present, most of the common glass molding machines on the market use a screw module to drive the lower mold core to rise, and then the lower mold core cooperates with the upper mold core to perform molding work in a vacuum environment, thereby forming glass products. Moreover, the start or stop of the screw module is controlled by the simple molding position, and the precision of the glass product is guaranteed by the complete fit of the lower mold core and the upper mold core. [0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defe...

Problems solved by technology

[0005] The purpose of the embodiments of the present application is to provide a glass molding machine to solve the following technical problems: during the molding process of glass products, there will be phenomena such as uneven heating and low glass center temperature. At this time, the glass is not completely softened. In this case, if only simple position control is used, it will easily lead to an increase in molding pressure, crushing glass products, and a relatively high product scrap rate, so it needs to be improved.
