And on both ends of the middle mold 2 close to the hinge with the upper mold 3, driven blocks 5 are fixedly connected. The inner sides of the driven blocks 5 and the rotating blocks 4 are mutually attached. And a convex block facing the driven block 5 is fixedly connected to the end of the rotating block 4 away from the upper mold 3. A pulling handle 6 is fixedly connected to the top of the end of the upper mold 3 away from the hinge with the middle mold 2, and a fixed handle 7 is fixedly connected to the end of the bottom mold 1 away from the hinge with the middle mold 2.

[0030] A forming block is fixedly connected to the top of the end of the bottom mold 1 away from the hinge with the middle mold 2. And a first forming cavity 9 is provided inside the forming block, and an annular first forming groove 8 is provided on the top of the forming block.

[0031] Inside the bottom mold 1, there are two first heating wires 10, and the two first heating wires 10 are respectively located on the outer side of the bottom of the first forming cavity 9 and at the bottom of the first forming groove 8. The first heating wire 10 located at the bottom of the first forming cavity 9 is distributed in a circular structure inside the bottom mold 1.

[0032] On the top of the middle mold 2, there is a second forming groove 11 distributed in a circular structure. The two ends of the second forming groove 11 are aligned with the two ends of the first forming groove 8. One end of the middle mold 2 far from the hinge connection with the bottom mold 1 is fixedly connected with a core mold 12, and the core mold 12 is located inside the first forming cavity 9.

[0033] Inside the middle mold 2, there is a fixedly connected second heating wire 13. The slipper body is located outside the middle mold 2 and is snap - connected to the outside of the core mold 12.

[0034] The two ends of the second forming groove 11 are aligned with the two ends of the first forming groove 8 to form a circular structure. On the outside of this circular structure, there is a sealing groove 16 distributed in a circular structure, and the sealing groove 16 is respectively located on the tops of the bottom mold 1 and the middle mold 2.

[0035] On one side of the upper mold 3 close to the middle mold 2, there is a second forming cavity 14. On the outside of the second forming cavity 14, there is a sealing ring 17 fixedly connected in a circular distribution. The sealing ring 17 is snap - connected to the inside of the bottom mold 1 and the first forming groove 8, and inside the upper mold 3, there is a fixedly connected third heating wire 15.

[0036] Embodiment Two:

[0037] On the basis of Embodiment One, its specific working principle is as follows:

[0038] For this pre - heating type slipper processing and forming mold, first pull the handle 6 to drive the upper mold 3 to rotate around the end of the middle mold 2. During the rotation of the upper mold 3, the rotating block 4 will slide along the side of the driven block 5 until the convex block at the bottom of the rotating block 4 drives the driven block 5 to move. At this time, the rotating block 4 will drive the middle mold 2 to rotate around the bottom mold 1, making the bottom mold 1 in the Figure 1 state shown, which is convenient for removing the slipper outside the core mold 12;

[0039] Before the material is added into the interior of the mold, the first heating wire 10, the second heating wire 13 and the third heating wire 15 are electrified, so that the first heating wire 10 heats the inner side of the first forming cavity 9 and the top of the bottom mold 1, the second heating wire 13 heats the top of the middle mold 2, and the third heating wire 15 heats the second forming cavity 14 at the bottom of the upper mold 3. After the material is added into the interior of the mold, due to the increase in the temperatures of the bottom mold 1, the middle mold 2 and the upper mold 3, the forming space formed by the first forming groove 8, the first forming cavity 9, the second forming groove 11 and the second forming cavity 14 has a relatively high temperature, thereby improving the fluidity of the material, enabling the material to flow more evenly, reducing surface defects, improving the appearance quality of the slipper, ensuring that the material can better fill each detail of the mold, and at the same time reducing bubbles and defects. Further, maintaining the mold temperature reduces energy loss;

[0040] By heating the bottom mold 1, the middle mold 2 and the upper mold 3 with the first heating wire 10, the second heating wire 13 and the third heating wire 15, the temperature change of the mold during the forming process is reduced, and the risk of thermal fatigue is lowered, thereby extending the service life of the mold.
