A mould ejection plate can return early, and a thimble can be prevented from impacting a sliding block.

Description

Mould built-in morning of return mechanism

Technical field

The utility model relates to mould manufacturing field, particularly a kind of mould built-in morning of return mechanism.

Background technology

Injection molding process is to adopt injection machine by machine-shaping plastic product in the mold cavity of thermoplastic injection as supporting connection with it.Current injection forming mold as shown in Figure 1, in mould, there is slide block 10 and thimble 20, because push pedal 40 is by release link 30 returns, while having thimble 20 in the travel range of slide block 10 simultaneously, thimble 20 and the very possible collision occurring as shown in Figure 1 of slide block 10, cause very macrolesion.

Utility model content

The utility model provides a kind of mould built-in morning of return mechanism, to avoid thimble and slide block in mould to bump.

For solving the problems of the technologies described above, the utility model provides a kind of mould built-in morning of return mechanism, comprising: top is fixed on the reset push rod in push pedal, the reset ejector sleeve corresponding with described reset push rod bottom, and the guide pin bushing that is arranged on described reset ejector sleeve top; Described reset push rod and reset ejector sleeve and guide pin bushing interoperation, drive push pedal return.

As preferably, described reset ejector sleeve comprises: base, be arranged on the guide pillar on described base, and the claw that is located at described guide pillar surrounding.

As preferably, the height value of described guide pillar is greater than Angle Pin in the standoff height value of vertical direction.

As preferably, described guide pin bushing is fixed in male model plate.

As preferably, the bottom of described reset ejector sleeve is fixed on upper ejector plate.

Compared with prior art, of the present utility model kind of mould built-in morning of return mechanism, comprising: comprising: top is fixed on the reset push rod in push pedal, the reset ejector sleeve corresponding with described reset push rod bottom, and the guide pin bushing that is arranged on described reset ejector sleeve top; Described reset push rod and reset ejector sleeve and guide pin bushing interoperation, drive push pedal return.The built-in mould inside that is arranged on of mould of the present utility model built-in morning of return mechanism, takes up room little and is convenient to install, and can realize early return of mould-ejecting plate, prevents that thimble and slide block from bumping against.

In Fig. 1: 10-slide block, 20-thimble, 30-release link, 40-push pedal.

In Fig. 2～4: liftout plate, 600-slide block, 700-thimble, 800-Angle Pin, 900-male model plate under 100-reset push rod, 200-reset ejector sleeve, 210-base, 220-guide pillar, 230-claw, 300-guide pin bushing, 400-push pedal, 510-upper ejector plate, 520-.

The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.It should be noted that, the utility model accompanying drawing all adopts the form of simplification and all uses non-ratio accurately, only in order to convenient, the object of aid illustration the utility model embodiment lucidly.

Please refer to Fig. 2, mould built-in morning of the return mechanism that the utility model provides, comprise: top is fixed on the reset push rod 100 in push pedal 400, the reset ejector sleeve 200 corresponding with described reset push rod 100 bottoms, and the guide pin bushing 300 that is arranged on described reset ejector sleeve 200 tops; Described reset push rod 100 and reset ejector sleeve 200 and guide pin bushing 300 interoperations, drive push pedal 400 returns.The built-in mould inside that is arranged on of mould of the present utility model built-in morning of return mechanism, takes up room little and is convenient to install, and can realize early return of mould-ejecting plate, prevents that ejection piece from being that thimble 700 bumps against with slide block 600.

Please refer to Fig. 3～4, in conjunction with Fig. 2, described reset ejector sleeve 200 comprises: base 210, be arranged on the guide pillar 220 on described base 210, and the claw 230 that is located at described guide pillar 220 surroundings.In the utility model, the number of claw 230 is 4.Further, the height value B of described guide pillar 220 is greater than Angle Pin 800 at the standoff height value H of vertical direction, guarantees that slide block 600 and thimble 700 avoid completely.Four claws 230 that reset during mould ejection on ejector sleeve 200 are subject to squeezing to be pushed interior contraction to and enters in the guide pin bushing 300 in male model plate 900, and now, upper and lower liftout plate 510,520 is motionless, and push pedal 400 continues to rise.

As preferably, described guide pin bushing 300 is fixed in male model plate 900, and the bottom of described reset ejector sleeve 200 is fixed on upper ejector plate 510.

Continue referring to Fig. 2～4, in the time of describing folding mould in detail below, the course of work of the present utility model:

1. during mould ejection, reset push rod 100 and upper and lower liftout plate 510,520 and thimble 700 upwards eject simultaneously, and meanwhile, push pedal 400 drives Angle Pins 800 to rise, be with movable slider 600 outwards to move simultaneously; Then, four claws 230 on reset ejector sleeve 200 are subject to squeezing to be pushed interior contraction to and enters in the guide pin bushing 300 in male model plate 900, upper and lower liftout plate 510,520 and thimble 700 are slack, and push pedal 400 drives Angle Pin 800 to continue to rise, and slide block 600 continues mobile thereupon;

2. during mould matched moulds, 4 claws 230 of reset ejector sleeve 200 outwards open without space guide pin bushing 300 is interior, under reset push rod 100 thrusts, push pedal 400 are pushed back; At put in place the ejector sleeve 200 that resets of push pedal 400 simultaneously, exit guide pin bushing 300, four claws 230 of reset ejector sleeve 200 outwards open, and reset push rod 100 enters reset ejector sleeve 200, continue motion not affecting in push pedal 400 situations, until matched moulds completely.

To sum up, mould built-in morning of the return mechanism that the utility model provides, comprising: top is fixed on the reset push rod 100 in push pedal 400, the reset ejector sleeve 200 corresponding with described reset push rod 100 bottoms, and the guide pin bushing 300 that is arranged on described reset ejector sleeve 200 tops; Described reset push rod 100 and reset ejector sleeve 200 and guide pin bushing 300 interoperations, drive push pedal 400 returns.The built-in mould inside that is arranged on of mould of the present utility model built-in morning of return mechanism, takes up room little and is convenient to install, and can realize early return of mould-ejecting plate, prevents that ejection piece from being that thimble 700 bumps against with slide block 600.

Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these change and modification.
