Slow secondary core-pulling mechanism.
The present invention in order to solve its above-mentioned technical problem used by technical scheme be：A kind of line position delay of injection mold
Secondary core-pulling mechanism, including big line position, the small line position against big line position, fixed block, first reset lever and provided with elastic construction
Flexible mold insert, for the flexible mold insert in the fixed block, the first reset lever is laterally positioned in the top of the adjustable spring
End, the flexible mold insert top side are provided with rake, and opposite side is provided with inclined-plane guide groove, and one end of the first reset lever is provided with
Sliding part, the sliding part are stretched into the small line position, and the sliding part is provided with inclined plane and inclined thrust surface, and the sliding part exists
The inclined plane promotes the flexible mold insert to move the rake contact during motion, and the inclined thrust surface contacts to the guide groove
Promote the flexible mold insert motion.
Specifically, the other end of the first reset lever is provided with connecting portion, the connecting portion is " L " type, is embedded in big row
In position, the first reset lever is provided with fixing hole, and the first reset lever is fixedly connected on institute by screw through the fixing hole
State big line position.
Specifically, the line position delay secondary core-pulling mechanism of the injection mold also includes mold base, the fixed block passes through spiral shell
Silk is fixed on mold base.
Specifically, vertical height during the complete contraction of the flexible mold insert is not higher than the vertical height of fixed block, it is described
Elastic construction be spring.
The present invention has advantages below and beneficial effect compared with prior art：Its small line position is fixed using spring mold insert,
After big line position drives first reset lever motion to back to certain distance, small line position further plays retrogressing, and the line position of injection mold is prolonged
The movement structure of slow secondary core-pulling mechanism is designed using mechanical structure, spatially compact by simplifying the structure for complexity, is saved
Cost and injection machine resource, while the mechanism safety and stability, are more easily promoted.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.

Embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are unlimited
In this.
A kind of line position delay secondary core-pulling mechanism of injection mold of the present invention is illustrated referring to figs. 1 to Fig. 5, this
Embodiment provides a kind of line position delay secondary core-pulling mechanism of injection mold, including big line position 5, the small row on the left of big line position
Position 6, fixed block 1, first reset lever 3 and the flexible mold insert 2 provided with elastic construction, the flexible mold insert 2 are located at the fixed block 1
Interior, the first reset lever 3 is laterally positioned in the top of the flexible mold insert 2, and the flexible top side of mold insert 2 is provided with rake
21, opposite side is provided with inclined-plane guide groove 22, and one end of the first reset lever 3 is provided with sliding part, and the sliding part stretches into small line position 6
In, the sliding part is provided with inclined plane 31 and inclined thrust surface 32, and sliding part inclined plane 31 in motion is inclined to described
The contact of inclined portion 21 promotes the flexible mold insert 2 to move, and the inclined thrust surface 32 promotes the flexible mold insert 2 to the guide groove 22 contact
Motion
The other end of the first reset lever 3 is provided with connecting portion, and the connecting portion is " L " type, is embedded in big line position 5,
The first reset lever 3 is provided with fixing hole, and the first reset lever 3 is fixedly connected on described big by screw through the fixing hole
In line position 5.
The line position delay secondary core-pulling mechanism of the injection mold also includes mold base, and the fixed block 1 is screwed
On mold base.
Vertical height during the complete contraction of the flexible mold insert 2 is not higher than the vertical height of fixed block 1, described elasticity
Structure is spring 4, ensures to stretch into fixed block 1 in the sliding part compression of connection sheet.
