Technical solution adopted in the utility model are as follows:
A kind of mold is buckled to core-pulling device, including driving plate, push plate, plastic back-off, mobile jib and grab, in the driving plate
Between be fixed with secondary bar, secondary bar top is wider than lower part, and the second inclined-plane of secondary bar, the ipsilateral pair with the second inclined-plane of secondary bar are equipped at the top of secondary bar
Bar middle and upper part is equipped with the first inclined-plane of secondary bar, is equipped with spring positioned at the driving plate of secondary bar lower side, is equipped in the push plate
Slide, mobile jib are seated on slide, and spring is fixed between slide and driving plate, and the card at the top of mobile jib is blocked in the plastic back-off
Hook, side is equipped with the second inclined-plane of mobile jib cooperated with the second inclined-plane in the middle part of mobile jib, under the mobile jib ipsilateral positioned at the second inclined-plane of mobile jib
Portion is equipped with the first inclined-plane of mobile jib cooperated with the first inclined-plane, is provided with through-hole, through-hole interpolation pin among mobile jib ontology, pin is fixed
On core model, mobile jib is rotated around pin.
The secondary bar uplink range is no more than the bottom of plastic back-off.
The slide and driving distance between plates is greater than secondary bar uplink range.
First inclined-plane of secondary bar and the second inclined-plane of secondary bar is outer convex inclined plane, and it is oblique that the second inclined-plane of mobile jib is located at secondary bar second
Above face and parallel with the second inclined-plane of secondary bar, the first inclined-plane of mobile jib is located at below the first inclined-plane of secondary bar and puts down with the first inclined-plane of secondary bar
Row.
The utility model has the beneficial effects that by using wabbler mechanism as the core pulling liftout attachment of plastic mould, the device
Simple in sturcture, ingenious in design, smooth operation solves that mandril is too long to have the defects that mechanical strength is low, easy fracture, makes to be buckled to mould
Tool easily takes out.
