The anti-sticking molding plastic mold with the inner core pulling structure as shown in fig. 6-16 comprises a sliding block 1, at least one inclined guide post 2, a shovel machine 3, an inner core pulling core 4 and a plastic product 10, wherein the at least one inclined guide post 2 is obliquely arranged in the sliding block 1, the sliding block 1 extends out of the lower end part of the at least one inclined guide post 2, the shovel machine 3 is connected with the sliding block 1, one end of the inner core pulling core 4 is arranged in the sliding block 1, the end part, located in the sliding block 1, of the inner core pulling core 4 is connected with the at least one inclined guide post 2, a core 41 is arranged on the inner core pulling core 4, and the core 41 is arranged in the. And an inclined guide pillar pressing plate 11 is arranged on the sliding block 1. And, the oblique guide post 2 is a cylindrical rod.

The inner core is provided with a slide block insert 42 on the inner core-pulling 4, one end of the slide block insert 42 is arranged on the inner core-pulling 4, the other end of the slide block insert 42 extends out of the inner core-pulling 4, the core 41 is arranged on the end part of the slide block insert 42 extending out of the inner core-pulling 4, and the end part of the slide block insert 42 extending out of the inner core-pulling 4 can extend into the plastic product 10.

In addition, the slide block 1 is provided with at least one through hole I12, the through hole I12 is arranged obliquely, the inclined guide post 2 can be inserted into the through hole I12, and a gap 13 is arranged between the inclined guide post 2 and the inner wall of the through hole I12. The utility model discloses a core-pulling device, including inner core 4, slider 1, lug 43, arc groove 44, the both sides wall of lug 43, the arc groove 44 that all is equipped with lug 43 to the lower terminal surface of slider 1, lug 43 sets up in groove 14, all be equipped with arc groove 44 on the both sides wall of lug 43, the arc groove 44 symmetry in lug 43 both sides sets up, the figure of oblique guide pillar 2 is two to oblique guide pillar 2 sets up in arc groove 44, the oblique guide pillar 2 symmetry in arc groove 44 sets up, the slope of arc groove 44 and through-hole 12 is the same, arc groove 44 and through-hole 12 can be passed to oblique guide pillar 2.

In addition, the first inclined surface 15 is arranged on the sliding block 1, the second inclined surface 45 is arranged on the protruding block 43, the third inclined surface 31 is arranged on the shovel machine 3, and the third inclined surface 31 is attached to the first inclined surface 15 and the second inclined surface 45.

In the structure, the inner core pulling core 4 is internally provided with the connecting rod 46, and the sliding block insert 42 is connected with the connecting rod 46. And a second through hole 17 is formed in the slide block 1, and the core 41 can extend out of the second through hole 17.

Referring to fig. 1-5, a position a in fig. 1 is a core pulling position, a core pulling inner hole is a functional part, and a mold needs to be designed and manufactured according to a product 3D, so that the product is not allowed to deform. In the product structure, because the deep hole at the position B in the figures 2 and 3 can generate large packing force, the slide block is in die stripping, and the risk of die sticking exists.

The utility model discloses an anti-sticking plastic mould theory of operation with inner core structure of loosing core:

1. the injection molding machine molds and simultaneously injects a product, and the mold is opened under the acting force of the machine table.

2. When the mould is opened, the shovel contact surface leaves the slider inclined plane, and the oblique guide pillar begins work, because there is the interval between oblique guide pillar and the slider, the guide pillar can stir the inner core at first to loose core and move backward to the oblique guide pillar. Because the sliding block does not move in the process, the product can be always blocked by the sliding block when the inner core pulling core retreats until the inner core pulling core moves backwards to remove the inner hole packing force of the product.

3. When the mold is continuously opened and the gap between the inclined guide post and the sliding block is not available, the inclined guide post can simultaneously pull the sliding block and the inner core loose core to move backwards, and the inclined guide post stops moving until the inclined guide post is completely separated from the sliding block. Therefore, the slider finishes the first retreating of the core-pulling of the first die-sinking inner core to remove the wrapping force, and the core-pulling of the second die-sinking inner core and the slider simultaneously move backwards continuously until the product is pulled out of the back-off buckle. The product is not damaged and pulled due to the backward movement of the sliding block caused by overlarge wrapping force.

4. And (4) completely ejecting the product, taking out the mechanical arm and repeatedly starting to act.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principles of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
