Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The vacuum injection molding machine of the present invention uses the high-viscosity fluid metering device, such as figure 1 As shown, it includes a piston cylinder 5, a fluid delivery mechanism and a reciprocating transmission mechanism.

[0024] The upper end of the piston cylinder 5 is threadedly equipped with an upper sealing cover 14, and the upper end of the upper sealing cover 14 is provided with a fastening handle 15. The staff can install the upper sealing cover 14 on the upper end of the piston cylinder 5 by twisting the fastening handle 15, and the upper sealing The side of cover 14 is provided with the liquid inlet that communicates with piston cylinder 5 inner cavity; match.

[0025] Such as figure 2 As shown, the fluid delivery mechanism is mainly composed of a first solenoid valve 1 , a standpipe 2 and a second sole...

Abstract

The invention discloses a high-viscosity fluid metering device used for a vacuum injection molding machine. The high-viscosity fluid metering device comprises a piston cylinder, a fluid conveying mechanism and a reciprocating transmission mechanism, and an upper sealing cover is detachably installed on the upper end of the piston cylinder; the sealing cover is provided with a liquid inlet port, a lower sealing cover is arranged at the lower end of the piston cylinder, and the piston cylinder is internally provided with a piston; the fluid conveying mechanism comprises a vertical tube, and a first solenoid valve is arranged at the upper end of the vertical tube; a liquid conveying connector is arranged at the middle of the vertical tube, the liquid conveying connector is connected with the liquid inlet port, and a second solenoid valve is arranged at the lower end of the vertical tube; and the output end of the reciprocating transmission mechanism is fixedly connected with the lower end of the piston. The high-viscosity fluid metering device used for the vacuum injection molding machine is simple in structure, small in overall size, high in metering precision, and the high-viscosity fluid metering device can be installed in a narrow space of the vacuum injection molding machine, and the metering problem of a high-viscosity fluid of the vacuum injection molding machine is solved.

Description

technical field [0001] The invention belongs to the technical field of metering devices, in particular to a metering device for high-viscosity fluid used in a vacuum injection molding machine. Background technique [0002] As a quantitative conveying equipment, metering pumps are mainly divided into diaphragm metering pumps and plunger metering pumps, which have the advantages of high precision, high degree of adjustment, good sealing and safety, etc., and have been widely used in petroleum, chemical, pharmaceutical and modern The field of automatic production technology. [0003] The characteristic of the diaphragm metering pump is that it can completely isolate the conveying medium, but its suction and discharge capacity is insufficient, the structure is complex, and the volume is large, so it is not suitable for the metering of high-viscosity fluids in a limited space environment; in addition, the diaphragm metering pump is used in long-term production work During the pr...
