Automatic feeding structure for APG (Automatic Pressure Gel) forming process

Abstract

The invention relates to an automatic feeding structure for an APG (Automatic Pressure Gel) forming process. The automatic feeding structure comprises a main body material tank, a sight glass on the main body material tank, a plug valve connected below the main body material tank and a forming machine connected with the plug valve, the forming machine and a PLC (Programmable Logic Controller) work station are connected, a motor is arranged on the main body material tank, and an air intake ball valve and an air release ball valve are respectively connected with the main body material tank; the main body material tank is also connected with a safety valve, the air release ball valve is connected with a pressure valve, and air intake ball valve is connected with an air compressor through an air storage tank. The automatic feeding structure also comprises a constant pressure valve and a power valve, wherein the constant pressure valve is arranged between the air intake ball valve and the main body material tank; the power valve is arranged between the plug valve and the forming machine and is also connected with the PLC work station. The invention has the advantages of ensuring the stability of the production process, enabling the material tank to sustain certain process parameter requirements and keeping injection pressure unchanged; the invention has energy saving and consumption reduction and does not require pressure relief after applying a certain pressure to the material tank.

Description

Technical field: [0001] The invention relates to an APG process, in particular to a material injection structure in the APG process. technical background: [0002] The APG process refers to Automatic Pressure Generator, which is a process in which epoxy resin material is injected through a thermosetting mold. [0003] In the prior art, each production of APG adopts manual pressurization and pressure release for material injection. like figure 1 Shown: in the figure: material tank 1; material tank upper view mirror 2; cock valve 12 connected under the material tank; forming machine 9 connected with cock valve 12; forming machine 9 is connected with PLC workstation 10; The motor 3; the inlet ball valve 61 and the discharge ball valve 62 are respectively connected to the main material tank 1; a safety valve 7 is also connected on the material tank; the discharge ball valve 62 is connected to the pressure valve 4; the inlet ball valve 61 passes through the gas storage tank 71 ...

AI Technical Summary

Problems solved by technology

[0004] In the above structure, the inlet ball valve 61 and the discharge ball valve 62 are manually controlled by the main material tank 1 for injection production; however, due to the instability of the production pressure, the material properties will change accordingly as time goes on, which will affect the quality of the product. Stability is limited
