Abstract

The utility model discloses an external ejection mechanism of a plastic pipe fitting mould product. The external ejection mechanism comprises a fixed cavity plate and a fixed core plate of a mould, wherein a fixed mould plate is mounted under the fixed cavity plate; a fixed mould insert is mounted in the fixed mould plate; two mould legs are mounted on the fixed core plate; a moving mould bottom plate is mounted on the two mould legs; a moving mould plate is mounted on the moving mould bottom plate; a moving mould insert is mounted in the moving mould plate; a mould cavity is formed between the moving mould insert and the fixed mould insert; a pipe fitting inner wall core is arranged in the mould cavity; an upper ejection plate and a lower ejection plate are arranged between the two mould legs; the upper ejection plate is connected with an ejection pin. The external ejection mechanism is characterized in that the mould cavity comprises a pipe fitting body mould cavity and a pipe fitting flaring mould cavity; an ejection mould cavity is formed in the moving mould insert on one side of the pipe fitting flaring mould cavity and is communicated with a flaring mould cavity through a connecting flow channel; the ejection pin penetrates through the moving mould bottom plate, the moving mould plate and the moving mould insert to be matched with the ejection mould cavity. According to the external ejection mechanism, a plastic pipe fitting formed through the scheme is free of ejection marks on the upper and lower surfaces and is smooth, attractive, good in quality and high in grade.

Description

The outer ejecting mechanism of plastic pipe fitting mould product
Technical field
The utility model relates to the outer ejecting mechanism of a kind of plastic pipe fitting mould product, belongs to mould of plastics field, is mainly used in processing plastic pipe fitting etc.
Background technology
Adopt mould of plastics to produce plastic product, as plastic pipe (elbow) etc., product, after injection mo(u)lding, needs first loose core to the inwall of pipe fitting, after the inwall fuse of pipe fitting is extracted out, then drive thimble by outside product ejection die by the ejecting mechanism of the powered mould of injection machine.But prior art thimble is generally all withstanding on time outside product ejection die the body outer wall of product, product after completely cooling, has top trace one at the body outer wall of product, affects aesthetic in appearancely, reduces product specification.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, provides one at product ontology peripheral hardware top set material, and thimble withstands on liftout, makes product ontology without top trace, and product shape is attractive in appearance, and quality is good, the outer ejecting mechanism of plastic pipe fitting mould product that class is high.
The technical scheme of the outer ejecting mechanism of the utility model plastic pipe fitting mould product is: comprise compound plate and lower compound plate on mould, under upper compound plate, solid plate is installed, fixed die insert is installed in solid plate, two mould pin are installed on lower compound plate, on two mould pin, moving clamping plate is installed, moving platen is installed on moving clamping plate, moving die insert is installed in moving platen, between moving die insert and fixed die insert, be provided with die cavity, in die cavity, be provided with pipe fitting inner wall fuse, between two mould pin, upper plate and lower roof plate are set, connecting ejector pin on upper plate, it is characterized in that described die cavity comprises pipe fitting body die cavity and pipe fitting expanding die cavity, liftout die cavity is set on the moving die insert of pipe fitting expanding die cavity one side, liftout die cavity is communicated with enlarging die cavity through connecting passage, thimble is through moving clamping plate, moving platen and moving die insert match with liftout die cavity.
The outer ejecting mechanism of plastic pipe fitting mould product of the present utility model, main feature is that liftout die cavity is set on moving die insert, liftout die cavity is communicated with enlarging die cavity through connecting passage, plastic pipe fitting is in the time of injection mo(u)lding, and the plastic raw materials of melting flows into liftout die cavity through connecting passage from enlarging die cavity, and type becomes a liftout, in connecting passage, there is connection clout, while ejecting, thimble withstands under liftout, by outside plastic pipe ejection die.Liftout is positioned at enlarging one side of plastic pipe, can liftout and connection clout be removed by machine or manually, does not affect this weight of pipe fitting.By the plastic pipe of this programme machine-shaping, not top trace of the upper and lower surface of plastic pipe, product is smooth, attractive in appearance, and quality is good, and class is high.
The outer ejecting mechanism of plastic pipe fitting mould product of the present utility model, described liftout die cavity be circular, the bore of circular liftout die cavity is identical with the diameter of thimble, and liftout is coordinated closely with liftout die cavity, reliably.
Brief description of the drawings
Fig. 1 is the outer ejecting mechanism structural representation of the utility model plastic pipe fitting mould product;
Fig. 2 arranges liftout die cavity top view on moving die insert of the present utility model.
Detailed description of the invention
The utility model relates to the outer ejecting mechanism of a kind of plastic pipe fitting mould product, comprise compound plate 1 and lower compound plate 2 on mould, solid plate 3 is installed under upper compound plate, fixed die insert 5 is installed in solid plate, two mould pin 6 are installed on lower compound plate, on two mould pin, moving clamping plate 7 is installed, moving platen 8 is installed on moving clamping plate, moving die insert 9 is installed in moving platen, between moving die insert 9 and fixed die insert 5, be provided with die cavity, in die cavity, be provided with pipe fitting inner wall fuse 10, upper plate 17 and lower roof plate 18 are set between two mould pin 6, connecting ejector pin 19 on upper plate, described die cavity comprises pipe fitting body die cavity 11 and pipe fitting expanding die cavity 12, on the moving die insert 9 of pipe fitting expanding die cavity 12 1 sides, liftout die cavity 15 is set, liftout die cavity 15 is communicated with enlarging die cavity 12 through connecting passage 16, thimble 19 is through moving clamping plate 7, moving platen 8 and moving die insert 9 match with liftout die cavity 15.The main feature of this programme is that liftout die cavity 15 is set on moving die insert 9, liftout die cavity 15 is communicated with enlarging die cavity 12 through connecting passage 16, plastic pipe fitting is in the time of injection mo(u)lding, the plastic raw materials of melting flows into liftout die cavity 15 through connecting passage 16 from enlarging die cavity 12, type becomes a liftout, has connection clout, while ejecting in connecting passage, thimble 19 withstands under liftout, by outside plastic pipe ejection die.Liftout is positioned at enlarging one side of plastic pipe, can liftout and connection clout be removed by machine or manually, does not affect this weight of pipe fitting.By the plastic pipe of this programme machine-shaping, not top trace of the upper and lower surface of plastic pipe, product is smooth, attractive in appearance, and quality is good, and class is high.Described liftout die cavity 15 is circular, and the bore of circular liftout die cavity 15 is identical with the diameter of thimble 19, and liftout is coordinated closely with liftout die cavity, reliably.
