It should be noted that, the ejection block 8 is made of PVA, which is a water-soluble polymer having good flexibility and heat resistance. It does not react with silica gel, so that it does not produce tackiness.

As a preferred embodiment of the present invention, a top plate 2 is disposed above the base 1, two support plates 20 are symmetrically and fixedly connected to the rear side of the bottom of the top plate 2, the bottom of the support plates 20 is fixedly connected to the top of the base 1, and a first hydraulic cylinder 30 for driving the upper die 3 to move up and down is mounted on the top plate 2. The first hydraulic cylinder 30 drives the upper die 3 to move up and down, so that the upper die 3 and the lower die 7 can be attached and detached.

As a preference of the embodiment, a driving plate 6 capable of moving up and down is arranged below the base 1, connecting rods 61 with the same number as the ejection blocks 8 are fixedly arranged at the top of the driving plate 6, and a plurality of connecting rods 61 are respectively positioned under a plurality of ejection blocks 8 and are respectively fixedly connected with the bottoms of a plurality of ejection blocks 8. In use, the ejector block 8 is driven to move up and down by moving the driving plate 6 up and down and then by the connecting rod 61. It should be added that the connecting rod 61 is connected with the lower die bin 4 in a sliding manner up and down.

As a preferable mode of this embodiment, two extension plates 60 are symmetrically and integrally formed on the driving plate 6, two second hydraulic cylinders 5 are symmetrically mounted on the base 1, and piston rods of the two second hydraulic cylinders 5 are fixedly connected with the two extension plates 60 respectively. In use, the second hydraulic cylinder 5 drives the extension plate 60 to move up and down, and further drives the driving plate 6 to move up and down.

Preferably, in this embodiment, when the piston rod of the second hydraulic cylinder 5 extends to the longest, the top of the protection pad 80 is flush with the inner wall of the lower die 7. Facilitating the return of pad 80 to its original position.

Preferably, in this embodiment, a supporting leg 10 is fixedly installed at four corners of the bottom of the base 1, and the height of the supporting leg 10 is greater than the length of a piston rod of the second hydraulic cylinder 5. For ensuring that the drive plate 6 can have space for movement.

Preferably, in this embodiment, the upper die 3 and the lower die 7 are completely separated when the piston rod of the first hydraulic cylinder 30 is retracted to the shortest. And a sufficient space is provided for taking out the product, so that the operator can conveniently carry out subsequent operation.

Preferably, the ejector block 8 does not disengage from the movable groove 70 during the up-and-down movement. The stability of the ejector block 8 is ensured, and at the same time, the design also avoids equipment failure or product damage caused by the falling-off of the ejector block 8.

When the flexible bottom-top type demolding device is used, the method comprises the following steps of:

Initial state: when the equipment does not start working, the upper die 3 and the lower die 7 are in a separated state, and the piston rod of the second hydraulic cylinder 5 is in a contracted state, so that the top of the protection pad 80 is lower than the inner wall of the lower die 7. At this time, the ejector block 8 is completely received in the movable groove 70.

And (3) die assembly and injection molding: when the silica gel product is required to be produced, the first hydraulic cylinder 30 is started to push the upper die 3 to move downwards to be attached to the lower die 7, so that a closed die cavity is formed. Next, liquid silicone gel is injected into the cavity through the injection port 31 in the upper mold 3.

Cooling and solidifying: and cooling the liquid silica gel in the mold cavity and gradually solidifying and forming. In this process, the upper die 3 and the lower die 7 are kept in a fitted state, ensuring the shape and dimensional accuracy of the product.

Opening and ejecting: when the curing of the silica gel product is completed, the first hydraulic cylinder 30 moves reversely to drive the upper die 3 to move upwards to be separated from the lower die 7. Subsequently, the second hydraulic cylinder 5 is activated, pushing the extension plate 60 and the drive plate 6 to move upwards.

And (3) demolding a product: as the ejector block 8 is raised, its top pad 80 contacts the bottom of the silicone product and ejects it from the lower mold 7. Since the sticking between the pad 80 and the silicone product is not generated (since the ejection block 8 is made of PVA material), the silicone product can be smoothly released from the mold.

Taking out the product: the product is removed from the ejector block 8.

Resetting the device: after the silica gel product is taken out, the first hydraulic cylinder 30 and the second hydraulic cylinder 5 respectively drive the upper die 3 and the driving plate 6 (and the ejection block 8 thereon) to return to the initial positions. The device is ready for the next production cycle.
