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.

Embodiment 1

[0009] Embodiment 1: with reference to accompanying drawing 1. Low-pressure and large-capacity CNC extrusion plastic molding equipment, which includes a vertical mold clamping mechanism, the material storage extrusion cylinder 9 is processed and manufactured according to the existing technology and installed on rails 14 and 13 that can be moved by CNC in the X and Y horizontal directions. Material extrusion cylinder 9 is composed of nozzle valve 6, material storage cylinder 15 and extrusion oil cylinder 10. The piston in extrusion oil cylinder 10 and the inner wall of material storage cylinder 15 form a piston structure. Nozzle valve 6 communicates with the outlet of material storage cylinder 15. . The plasticizing screw 8 is processed and manufactured according to the prior art and is located on the material storage extrusion cylinder 9 and communicates with the storage material extrusion cylinder 9 through the valve 7. The screw in the plasticization screw 8 is a single-scre...

Embodiment 2

[0010] Example 2: Low-pressure and large-capacity CNC extrusion plastic injection molding process. Plastic enters the screw from the hopper, and after being plasticized by the plasticizing screw, it enters the storage tank through the valve through the screw rotation. After the storage is completed, the storage is squeezed out of the cylinder. The nozzle valve moves to the top of the mold cavity of the lower mold in the vertical mold clamping mechanism, and the oil cylinder pushes its piston to squeeze the material in the storage cylinder into the mold cavity quantitatively through the nozzle valve according to the instructions of the digital control system, and then exit the storage material extrusion Out of the cylinder, the upper and lower molds in the vertical mold clamping mechanism clamp and maintain pressure, and at the same time enter the next cycle of material storage. After the pressure is maintained, the mold is opened, and the manipulator enters the cavity to take ou...

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 ...
