[0024] By adopting the above technical solution, after the product is injection molded, the lower die base 11 is driven by the function switching mechanism 9 to move below the shaping mechanism 4. At this time, the third hydraulic cylinder 41 is opened, and the third hydraulic cylinder 41 drives the lifting plate 43 to descend to a specified position through the output end. Then, the second hydraulic cylinder 13 drives the ejector block 2 to eject the molded product from the inside of the lower die base 11, and then the shaping mechanism 4 performs the shaping work on the product.

[0025] Specifically, the shaping assembly 45 includes a rubber pad 451, a bidirectional lead screw 452, a shaping plate 453, a nut block 454, a first motor 455, and a sliding plate 456. A first motor 455 is arranged on the side of the lifting plate 43. The output end of the first motor 455 is provided with a bidirectional lead screw 452. Two groups of nut blocks 454 are symmetrically arranged on the surface of the bidirectional lead screw 452. The lower end of the nut block 454 is provided with a sliding plate 456. The lower end side of the sliding plate 456 is provided with a shaping plate 453. A rubber pad 451 is arranged on the side of the shaping plate 453.

[0026] By adopting the above technical solution, the first motor 455 is turned on. The first motor 455 drives the bidirectional lead screw 452 to rotate through the output end. The rotation of the bidirectional lead screw 452 drives the two groups of nut blocks 454 to approach each other. The approach of the two groups of nut blocks 454 drives the sliding plates 456 to approach each other. The approach of the sliding plates 456 drives the two groups of shaping plates 453 to approach each other, thereby applying a certain pressure to the side of the product, and thus realizing the shaping work on the product.

[0027] Specifically, the shaping assembly 45 further includes a slider 457 and a guide rod 458. The upper end of the sliding plate 456 is arranged inside the lifting plate 43 and is provided with a slider 457. A guide rod 458 is penetrated through the inside of the slider 457.

[0028] By adopting the above technical solution, when the sliding plate 456 slides, it will drive the slider 457 to slide on the surface of the guide rod 458, thereby improving the stability of the sliding process of the sliding plate 456.

[0029] In the use of this embodiment, first, the lower die holder 11 is driven by the function switching mechanism 9 to move below the upper die holder 7. Then, the first hydraulic cylinder 5 is opened, and the first hydraulic cylinder 5 drives the upper die holder 7 to descend. Immediately, the plastic solution is injected into the mold cavity 10 inside the lower die holder 11 through the injection pipe 8. When the product is injection-molded, the lower die holder 11 is driven by the function switching mechanism 9 to move below the shaping mechanism 4. At this time, the third hydraulic cylinder 41 is opened, and the third hydraulic cylinder 41 drives the lifting plate 43 to descend to a specified position through the output end. Then, the second hydraulic cylinder 13 drives the ejector block 2 to eject the molded product from the inside of the lower die holder 11. Immediately, the shaping mechanism 4 performs the shaping work on the product. The first motor 455 is turned on, and the first motor 455 drives the bidirectional lead screw 452 to rotate through the output end. The rotation of the bidirectional lead screw 452 drives the two nut blocks 454 to approach each other. The approach of the two nut blocks 454 drives the sliding plates 456 to approach each other. The approach of the sliding plates 456 drives the two shaping plates 453 to approach each other, thereby applying a certain pressure to the side of the product, thus realizing the shaping work on the product. When the sliding plate 456 slides, it will drive the slider 457 to slide on the surface of the guide rod 458, thereby improving the stability of the sliding process of the sliding plate 456.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that: the function switching mechanism 9 includes a sliding seat 91, a screw rod 92, and a second motor 95. A second motor 95 is arranged on the side of the base 1, a screw rod 92 is arranged at the output end of the second motor 95, and a sliding seat 91 is threadedly connected to the surface of the screw rod 92. The upper end of the sliding seat 91 is fixed to the lower surface of the lower die holder 11.

[0032] By adopting the above technical solution, when the second motor 95 is turned on, the second motor 95 drives the screw rod 92 to rotate through the output end, and the rotation of the screw rod 92 drives the sliding seat 91 to slide, so as to be able to drive the lower die holder 11 to move below the upper die holder 7 and move below the shaping mechanism 4 respectively.

[0033] Specifically, the function switching mechanism 9 further includes a contact switch 93, a contact head 94, and a controller 96. Contact heads 94 are arranged at both upper ends of the sliding seat 91, contact switches 93 are arranged at the corresponding positions of the two sides inside the base 1 for the contact heads 94, and a controller 96 is arranged on the other side of the base 1.

[0034] By adopting the above technical solution, when the sliding seat 91 moves below the upper die holder 7, at this time the contact head 94 will contact the contact switch 93, so as to drive the second motor 95 to turn off through the controller 96. When the sliding seat 91 moves below the shaping mechanism 4, at this time the contact head 94 will contact the contact switch 93 again, so as to drive the second motor 95 to turn off again through the controller 96.

[0035] In use of this embodiment, motor two 95 is turned on. Motor two 95 drives screw rod 92 to rotate through its output end. The rotation of screw rod 92 drives slide block 91 to slide, so as to drive lower die holder 11 to move respectively below upper die holder 7 and below the shaping mechanism 4. When slide block 91 moves below upper die holder 7, contact head 94 will contact contact switch 93 at this time, so as to drive motor two 95 to turn off through controller 96. When slide block 91 moves below the shaping mechanism 4, contact head 94 will contact contact switch 93 again at this time, so as to drive motor two 95 to turn off again through controller 96.

[0036] Working principle and usage process of the present utility model: When the present utility model is in use, first drive lower die holder 11 to move below upper die holder 7 through function switching mechanism 9. Turn on hydraulic cylinder one 5. Hydraulic cylinder one 5 drives upper die holder 7 to descend. Then inject plastic solution into the mold cavity 10 inside lower die holder 11 through injection pipe 8. When the product is injection molded, drive lower die holder 11 to move below the shaping mechanism 4 through function switching mechanism 9. At this time, turn on hydraulic cylinder three 41. Hydraulic cylinder three 41 drives lifting plate 43 to descend to the designated position through its output end. Then drive ejector block 2 to eject the molded product from the inside of lower die holder 11 through hydraulic cylinder two 13. Then carry out shaping work on the product through shaping mechanism 4. Turn on motor one 455. Motor one 455 drives bidirectional lead screw 452 to rotate through its output end. The rotation of bidirectional lead screw 452 drives two nut blocks 454 to approach each other. The mutual approach of two nut blocks 454 drives two slide plates 456 to approach each other. The mutual approach of two slide plates 456 drives two shaping plates 453 to approach each other, so as to apply a certain pressure to the side of the product, thus realizing the shaping work of the product. When slide plate 456 slides, it will drive slider 457 to slide on the surface of guide rod 458, so as to improve the stability of the sliding process of slide plate 456. Turn on motor two 95. Motor two 95 drives screw rod 92 to rotate through its output end. The rotation of screw rod 92 drives slide block 91 to slide, so as to drive lower die holder 11 to move respectively below upper die holder 7 and below the shaping mechanism 4. When slide block 91 moves below upper die holder 7, contact head 94 will contact contact switch 93 at this time, so as to drive motor two 95 to turn off through controller 96. When slide block 91 moves below the shaping mechanism 4, contact head 94 will contact contact switch 93 again at this time, so as to drive motor two 95 to turn off again through controller 96.
