[0035] like Figure 7 , Figure 8 , Figure 10As shown, the sliding member includes a slider base 7 and a slider insert 8 movably mounted on the slider base 7. The slider insert 8 can move away from or close to the slider base 7 along the sliding direction of the sliding member. An inner concave first mounting hole 9 is provided on the end face of the slider insert 8 facing the slider base 7, and an inner concave second mounting hole 10 is provided on the end face of the slider base 7 facing the slider insert 8. The first mounting hole 9 is aligned with the second mounting hole 10, and they have the same aperture; the center lines of the first mounting hole 9 and the second mounting hole 10 are parallel to the sliding direction of the sliding member; an elastic member is installed in the first mounting hole 9 and the second mounting hole 10, and the elastic member is always in a compressed state; in this embodiment, the elastic member is a spring, which is not shown in the figure.

[0036] As Figures 7-9 shown, the slider insert 8 is installed on the slider base 7 through a pin 11. The pin 11 penetrates through the slider base 7 and into the slider insert 8 at the same time. The tail of the pin 11 is fixed inside the slider insert 8, and the head of the pin 11 is embedded in the slider base 7. The slider base 7 can slide relative to the pin 11. The diameter of the cross-section of the tail of the pin 11 is smaller than the diameter of the cross-section of the head of the pin 11; the axis of the pin 11 is parallel to the sliding direction of the sliding member. A third mounting hole is penetrated through the slider insert 8, and an inner concave fourth mounting hole is provided on the end face of the slider base 7 facing the slider insert 8. The aperture of the fourth mounting hole is larger than that of the third mounting hole. The head of the dowel pin 4 is received in the fourth mounting hole and fixed therein. The body of the dowel pin 4 is received in the third mounting hole. The diameter of the cross-section of the body of the dowel pin 4 is smaller than the diameter of the cross-section of the head of the dowel pin 4, and the tail of the dowel pin 4 is located at one end of the body of the dowel pin 4 away from the head of the dowel pin 4; the axis of the dowel pin 4 is parallel to the sliding direction of the sliding member.

[0037] As Figures 7-9 shown, a first pin hole is penetrated through the slider insert 8. The tail of the pin 11 is fixed inside the slider insert 8 by a first pin shaft 12 passing through the first pin hole and the pin 11; the first pin shaft 12 and the first pin hole are in interference fit; a second pin hole is penetrated through the slider base 7.

[0038] An inclined guide hole 14 for inserting the inclined guide post 6 is penetrated through the slider base 7. The inclined guide hole 14 deviates from the vertical direction towards the side away from the slider insert 8; the surface of the slider base 7 that slides relatively frictionally with the chopping machine is an inclined surface, and a cushion block 15 is detachably installed on this inclined surface. When the cushion block 15 is worn, it can be replaced, so as to extend the service life of the slider base 7.

[0039] As Figure 4 、 Figure 5As shown, the track slab is slab B 16. The track assembly includes a first groove 17 formed in slab B 16, a second groove 18 opened downward at the bottom of the first groove 17, and a pair of pressing blocks 19 fixed to the bottom of the first groove 17.

[0040] Taking Figure 3 the direction as a reference, the working principle of a core-pulling mechanism for a slide block used in an HUD mold in the present invention is as follows: When the HUD mold is closed, under the action of the lifter 5, the slider insert and the slider base are in close contact with each other against the elastic force of the spring (as Figure 3 shown), and at the same time, the slider insert and the slider base are located at the leftmost end of their strokes; during the injection molding process, the hot plastic forms an undercut 1 with a cavity 2 in the product injection part 3 of the sliding part; after the injection molding is completed, when the mold is opened, the lifter 5 gradually leaves the sliding part following the A plate, and the inclined guide pillar 6 is gradually withdrawn from the inclined guide hole 14. At this time, under the elastic force of the spring, first the slider insert remains stationary, and the slider base gradually moves to the right away from the slider insert. After moving 5 mm to the right, under the action of the pin 11, the slider base stops moving relative to the slider insert; during the process of the slider base moving 5 mm to the right relative to the slider insert, the insert pin 4 moves to the right following the slider base and is withdrawn from the cavity 2 of the undercut 1, avoiding the adhesion of the insert pin 4 in the cavity 2 and making demolding more convenient; then as the lifter 5 continues to leave the sliding part following the A plate, the inclined guide pillar 6 continues to be withdrawn from the inclined guide hole 14, and the slider insert and the slider base move to the right together until the rightmost end of the stroke, and the undercut 1 of the HUD is demolded from the product injection part 3. Finally, the HUD is demolded from the product cavity under the ejection of the mold ejector pin.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention.
