Apparatus and process for forming low-pressure and large-capacity digital-controlled extruding pouring plastic

Abstract

The invention is concerned with the low-voltage big-capacity numerical control packing plastics equipment and the technics, it is: the plastic enters the screw from hopper, enters the storage jar by the rotation of the screw after plasticizing by the plasticizing screw, moves the nozzle valve of the storage extruding jar to the top mould cavity of the lower mould in the standing clapper die spotting press, the oil cylinder dosing pushes the piston to crushes in the mould cavity by passing the nozzle valve according to the order of the digital control system, exits the storage extruding jar, the top and bottom mould in standing clapper spotting press clapper die and keeping press, at the same time enters the next period, opens the mould after keeping press, the manipulator takes out the production from the mould cavity.

Description

Technical field: [0001] The invention relates to a thick-walled product, such as a filter plate of a filter press, an engineering plastic thick plate, a plastic building formwork, a plastic train track sleeper, a plastic manhole cover, a plastic rail, etc., and is also suitable for a thin-walled product, such as Equipment and processes for the manufacture of auto parts, small pleasure boats, plastic pump casings, plastic pipe fittings, logistics products, etc., which belong to the field of plastic extrusion forming equipment and extrusion process manufacturing. Background technique: [0002] With the development of technology and the wide application of engineering plastics, more and more large-scale and extra-large plastic products appear in people's production and life, which requires plastic forming equipment and molds to develop towards large and extra-large. , the manufacturing technical requirements and precision of the equipment are getting higher and higher, and the ...

Problems solved by technology

[0002] With the development of technology and the wide application of engineering plastics, more and more large-scale and extra-large plastic products appear in people's production and life, which requires plastic forming equipment and molds to develop towards large and extra-large. , the manufacturing technical requirements and precision of the equipment are getting higher and higher, and the requirements for the processing capacity, scope and materials of the equipment will be more stringent. The ensuing problem is that the equipment is expensive and the investment recovery period is long.
