At the same time, the aluminum sheet 100 loaded on the carrier block 32 is flipped vertically from the upward position to the side, so that the aluminum sheet 100 is aligned with the aluminum sheet attachment position 20, and then the driving force provided by other external mechanisms drives the slider 31 to slide, so that the aluminum sheet 100 is attached to the aluminum sheet attachment position 20. Based on the above action principle, the utility model can make the aluminum sheet accurately in place, effectively improving the quality of the injection molding process.

[0029] The two turning mechanisms 3 in this embodiment are preferably bilaterally symmetrical structures. Figure 2 and Figure 3As shown, the top surface and the left and right sides of the mold core 2 are formed with the aluminum sheet attachment positions 20. Correspondingly, the lower seat body 1 is provided with two flipping mechanisms 3, which are respectively arranged on the left and right sides of the mold core 2.

[0030] In this embodiment, combined with Figures 2 to 4 As shown, the flipping motion mechanism 30 includes a shaft 33 and a shaft driving mechanism 34 for driving the shaft 33 to rotate, and the slider 31 is arranged in the middle of the shaft 33 .

[0031] Furthermore, end shafts 330 are formed at both ends of the shaft body 33 , and two shaft seats 331 are fixed on the lower seat body 1 . The two end shafts 330 pass through the two shaft seats 331 , respectively, and the end shafts 330 are rotatably matched with the shaft seats 331 .

[0032] In the above structure, this embodiment preferably sets the shaft driving mechanism 34 directly on the lower seat body 1. Compared with the method of using external force to drive the shaft 33, this embodiment integrates the shaft 33 and the shaft driving mechanism 34 on the lower seat body 1, which can make the linkage performance between the shaft 33 and the shaft driving mechanism 34 better and ensure reliable transmission of torque.

[0033] As a preferred mode, the shaft driving mechanism 34 is preferably a cylinder driving mechanism. Specifically, a gear 332 is fixed on the end shaft 330. The shaft driving mechanism 34 includes a cylinder 340 and a vertically arranged spur rack 341. The spur rack 341 is fixed to the telescopic end of the cylinder 340. The spur rack 341 and the gear 332 are meshed with each other. When the cylinder 340 telescopes, the gear 332 is driven to rotate 90° by the spur rack 341. In this embodiment, the cylinder driving mode has the characteristics of strong driving ability and high motion accuracy.

[0035] In order to make the various structures on the lower seat body 1 compactly distributed and save the accommodating space of the shaft body 33, in the present embodiment, a shaft body accommodating groove 11 is opened on the lower seat body 1, the shaft body 33 is arranged in the shaft body accommodating groove 11, and two shaft seats 331 are respectively fixed at the two ends of the shaft body accommodating groove 11.

[0036] Regarding the overall structure of the mold, this embodiment includes an upper base body 4 assembled with the lower base body 1 from top to bottom, and the upper base body 4 covers the mold core 2 and the turning mechanism 3.

[0037] In this embodiment, the slider 31 and the shaft 33 are in a sliding matching relationship. Figures 6 to 8 As shown, a slide groove 334 is provided in the middle of the shaft body 33 , and the slider 31 is disposed in the slide groove 334 and the two slide in cooperation with each other.

[0038] As a preferred embodiment, two spring receiving grooves 335 are provided at the bottom of the slide groove 334, and a spring 336 is provided in the spring receiving groove 335. The spring 336 elastically abuts between the shaft 33 and the slider 31, and the spring 336 is used to drive the slider 31 to slide in a direction away from the mold core 2.

[0039] Furthermore, two support blocks 310 are fixed on the slider 31 , and support rods 311 are vertically provided at the ends of the support blocks 310 .
