Description
Technical field
The present invention relates to the air blowing assisted demoulding system of a kind of auxiliary demoulding mechanism for blowing noting embryo mould, particularly PP and PET bottle bottle base.
Background technology
The demoulding of PP infusion solutions preform mould product, the main lip module that relies on drives the reinforcing ring of bottle base outwards to move together when die sinking ejects.In the process due to the package power of product and core excessive time, product can not drop from core sometimes completely, causes again during matched moulds and product and mould parts is damaged by pressure, produces the situation of loss and breaks in production.
In order to ensure that bottle base completes smoothly when the demoulding; someone proposes practical mould threaded demoulding mechanism; its course of work is plastic injection, cooling, die sinking, thread core exit from automatic rotation workpiece, workpiece ejects by ejecting mechanism; because transmission mechanism exists gap; often there will be thread core motion not put in place or the excess of stroke; if thread core motion does not put in place; the shaping length of workpiece screw thread is just short; do not meet product quality requirement; thread core move distance is preferably fixed aborning, but this is difficult to again realize.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of and less, can to assist the bottle base demoulding and the high PP of finished product rate and PET bottle bottle base well air blowing assisted demoulding system is changed to original structure.
Object of the present invention is achieved through the following technical solutions: the air blowing assisted demoulding system of PP and PET bottle bottle base, it comprises note chamber, die lip, note core, note core retainer plate, slide plate and push pedal, note chamber is fixed in the plate of solid chamber, the side of die lip coordinates with the side in note chamber, the opposite side of die lip coordinates with note core retainer plate, note core retainer plate internal engagement is provided with note core, note core passes die lip and stretches into inside, note chamber, the outer wall of note core retainer plate is provided with slide plate and push pedal successively, air blowing mold insert is inlaid with between slide plate and push pedal, push pedal is provided with multiple gas hole and horizontal insufflation channel, each gas hole is corresponding with a horizontal insufflation channel respectively, air blowing mold insert is provided with multiple oblique insufflation channel, each oblique insufflation channel is communicated with corresponding horizontal insufflation channel, the afterbody of note core is also provided with solid central layer, Gu central layer coordinates with the end face of note core retainer plate and push pedal.
The axis of described note chamber, die lip and note core overlaps.
Described note core retainer plate respectively and push pedal and to note between core be matched in clearance.
The space that described note chamber, die lip, note core retainer plate enclose formation with note core is bottle embryo forming chamber.
The present invention has the following advantages: when die sinking, die lip ejects and drives the reinforcing ring of bottle base outwards to move together, pass into gases at high pressure from gas hole simultaneously, through horizontal insufflation channel and oblique insufflation channel, make the reinforcing ring of bottle base be subject to thrust further, move forward with bottle base, make the bottle base demoulding more smooth, reduce the percent defective of product, and insufflation channel is set in push pedal and air blowing mold insert, less to original structural change, maintenance cost is low.

In figure: 1, bottle embryo forming chamber, 2, note chamber, 3, die lip, 4, note core retainer plate, 5, note core, 6, solid chamber plate, 7, slide plate, 8, air blowing mold insert, 9, push pedal, 10, solid central layer, 11, gas hole, 12, oblique insufflation channel, 13, horizontal insufflation channel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, the air blowing assisted demoulding system of PP and PET bottle bottle base, it comprises note chamber 2, die lip 3, note core 5, note core retainer plate 4, slide plate 7 and push pedal 9, note chamber 2 is fixed in solid chamber plate 6, the side of die lip 3 coordinates with the side in note chamber 2, the opposite side of die lip 3 coordinates with note core retainer plate 4, note core retainer plate 4 internal engagement is provided with note core 5, note core 5 passes die lip 3 and stretches into inside, note chamber 2, the outer wall of note core retainer plate 4 is provided with slide plate 7 and push pedal 9 successively, air blowing mold insert 8 is inlaid with between slide plate 7 and push pedal 9, push pedal 9 is provided with multiple gas hole 11 and horizontal insufflation channel 13, each gas hole 11 respectively insufflation channel 13 horizontal with is corresponding, air blowing mold insert 8 is provided with multiple oblique insufflation channel 12, each oblique insufflation channel 12 is communicated with corresponding horizontal insufflation channel 13, the afterbody of note core 5 is also provided with solid central layer 10, Gu central layer 10 coordinates with the end face of note core retainer plate 4 and push pedal 9.
The space that note chamber 2, die lip 3, note core retainer plate 4 enclose formation with note core 5 is bottle embryo forming chamber 1, and the axis of note chamber 2, die lip 3 and note core 5 overlaps, and respectively and push pedal 9 and to note between core 5 be matched in clearance, the demoulding is more prone to described note core retainer plate 4.
As shown in Figure 2, during die sinking, note chamber 2 departs from die lip 3 together with solid chamber plate 6, and note chamber 2 departs from bottle embryo, realizes die sinking.
As shown in Figure 3, gas hole 11 passes into gases at high pressure, through horizontal insufflation channel 13 and oblique insufflation channel 12, carries out high pressure blow-gas when mould is opened to bottle embryo end face, can assist the demoulding of bottle embryo well, thus stop the hidden danger of pressing mold.
