[0034] Referring to Figures 2-4 Demolding mechanism 8 includes link plate 805, the top of link plate 805 is fixedly connected with demolding seat 801, both movement trajectories are consistent, and the top of demolding seat 801 is half rectangle, to facilitate the corresponding soft and hard combination board is placed in its interior, while the square groove matched with demolding seat 801 is set on lower die 7, so that soft and hard combination board can be contacted with the top of lower die 7, link plate 805 is fixedly connected with telescopic rod 802 on the side away from demolding seat 801, the overall length of telescopic rod 802 can be adjusted, and close to outer end can be moved horizontally, the top of support plate 4 is fixedly connected with guide plate 803, and support plate 4 can support guide plate 803, telescopic rod 802 is rotatably connected with rotating plate 804 on the inner wall of the side away from demolding seat 801, when rotating plate 804 rotates to horizontal state, it can be connected and installed on the inner wall of guide plate 803, the inner wall of rotating plate 804 is elastically connected with positioning pin 807 by connecting spring 808, and positioning pin 807 can play the role of limiting and fixing, the bottom end side wall of lower die 7 is provided with collecting mechanism 9, and the soft and hard combination board debris after press fit is collected by collecting mechanism 9.

[0035] Referring to Figures 3-5The outer walls of the demolding base 801, connecting plate 805, and telescopic rod 802 are all slidably connected to the inner wall of the lower mold 7. These three components form a single unit, allowing for vertical movement. A through-guide groove is formed on the outer wall of the guide plate 803. The side of the telescopic rod 802 away from the demolding base 801 contacts the inner wall of the through-guide groove. The through-guide groove allows the lower mold 7 to be moved forward, enabling the demolding of the pressed soft-hard bonded plate, thus facilitating removal. A connecting spring 808... One end is fixedly connected to the inner wall of the rotating plate 804, and the other end of the connecting spring 808 is fixedly connected to the outer wall of the positioning pin 807. The outer wall of the positioning pin 807 passes through and is slidably connected to the inner wall of the rotating plate 804. The elasticity of the connecting spring 808 enables the positioning pin 807 to have the functions of reset and limit. The outer wall of the telescopic rod 802 is provided with a insertion hole 806. The outer wall of the positioning pin 807 is inserted into the inner wall of the insertion hole 806. There are two sets of insertion holes 806 to facilitate connection and fixation with the positioning pin 807.

[0036] Reference Figure 2 and Figure 4 The collecting mechanism 9 includes a collecting plate 901, which can collect the debris after pressing, so as to facilitate the subsequent pouring and discharge of the debris for later use. A magnet 903 is fixedly connected to the front end of the lower mold 7, and a magnetic block 902 is fixedly connected to the front end of the collecting plate 901. The rear end of the magnetic block 902 is the negative pole, and the front end of the magnet 903 is the positive pole. The outer wall of the collecting plate 901 is slidably connected to the inner side wall of the lower mold 7. The two sides of the collecting plate 901 are T-shaped, which facilitates connection and positioning. The rear end of the magnetic block 902 is magnetically connected to the front end of the magnet 903. The magnetic connection between the two can achieve a certain fixed and limiting effect, preventing the collecting plate 901 from moving when the lower mold 7 moves.

[0037] Working principle: When personnel need to press the rigid-soft bonding plate, they first place the rigid-soft bonding plate on the four sets of demolding seats 801. Then, they drive the electric guide rail 5 through the corresponding buttons or knobs, causing the movable plate 6 and the lower mold 7 to move backward. When the movable plate 6 moves backward, it causes the outer end of the telescopic rod 802 to move inside the guide groove. Due to the guide groove, when the movable plate 6 moves backward, the telescopic rod 802 moves downward, causing the top of the demolding seat 801 to contact the lower mold 7. At this time, the rigid-soft bonding plate is attached to the upper part of the lower mold 7. When the lower mold 7 corresponds to the upper mold 3, the electric telescopic rod 2 is activated, which in turn drives the upper mold 3 to move downward. The plate moves to press against the lower mold 7, thereby pressing and discharging unwanted debris from the rigid-soft bond plate to the inner wall of the collection plate 901 for collection. When the debris inside the collection plate 901 reaches a certain level, the collection plate 901 can be removed and the debris poured out. Then, the collection plate 901 is installed inside the lower mold 7. When the collection plate 901 moves backward to the bottom, it is fixed by the magnetic force of the magnetic block 902 and the magnet 903. After the lower mold 7 is reset, the four sets of demolding seats 801 reset and extrude the rigid-soft bond plate. At this time, there is a certain space between the rigid-soft bond plate and the bottom of the lower mold 7, and the rigid-soft bond plate can be moved upward to remove it. The operation is simple and convenient.

[0038] When it is necessary to press different models of soft and hard composite plates, move the positioning pin 807 outward to release the insertion limit between the positioning pin 807 and the telescopic rod 802, and then rotate the rotating plate 804 to the horizontal direction. Then move the telescopic rod 802 towards the center so that the movable end (outer end) of the telescopic rod 802 and its rotating plate 804 are disengaged from the through guide groove, thereby releasing the screws or screw limit between the lower mold 7 and the movable plate 6, so as to remove and replace it. At the same time, replace the upper mold 3. The operation is simple and convenient.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
