AI Technical Summary
During the release process of existing EPS foam molds, the foam mass is smaller and easy to be damaged. The contact surface between the ejector rod and the foam is smaller, which easily damages the bottom and makes the liquid leak easily.
An EPS foam mold is designed including a mold and a sliding mechanism disposed at the bottom of the mold. The sliding mechanism consists of a working assembly and a sliding assembly, the working assembly including a first bevel block and a sliding block, and the sliding assembly includes a sliding block and a top plate. By manually pushing the fixing plate, the limiting column slides, and the sliding column and the second oblique block move, the first oblique block pushes the sliding block and the top plate downward, realizing the mold release of the foam.
This design effectively prevents foam from sticking to the inner wall of the mold, reduces the working time for workers, and improves the foam demolding efficiency and avoids foam damage.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example 1
[0024] like Figure 1-4 As shown, an EPS foam mold that is easy to demould includes a mold 1 and a sliding mechanism arranged at the bottom of the mold 1, and the sliding mechanism includes a working component and a sliding component;
[0025] The working assembly includes a first inclined block 2. The bottom of the mold 1 is provided with the first inclined block 2. The top of the first inclined block 2 is fixedly connected with a sliding block 3.
[0026] The sliding assembly comprises a sliding block 3 , the top end of which is fixedly connected to a top plate 4 .
[0027] Among them, Figure 3 As shown, the bottom surface of the sliding block 3 is fixedly connected to the top of the first inclined block 2. The appearance of the first inclined block 2 is triangular, which is conducive to the contact between the first inclined block 2 and the second inclined block 12. The opposite movement will cause the first inclined block 2 to push, providing an upward force to the top plate 4 to push the foam out.
[0028] Among them, Figure 3 As shown, the base 13 is provided with a sliding groove that matches the first inclined block 2. The first inclined block 2 forms a sliding structure with the base 13 through the second inclined block 12, which is conducive to the first inclined block 2 being able to slide stably in the groove, perform a lifting effect, and demould the foam.
[0029] Example 2
[0030] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, a handle 5 is provided at the bottom of the mold 1, one side of the handle 5 is fixedly connected to a fixed plate 6, the outer wall of the fixed plate 6 is fixedly connected to a connecting plate 7, one side of the connecting plate 7 is fixedly connected to a limiting column 8, one side of the fixed plate 6 is fixedly connected to a sliding column 9, the outer wall of the sliding column 9 is slidably connected to a fixing ring 10, one side of the fixing ring 10 is fixedly connected to a spring 11, one end of the sliding column 9 is fixedly connected to a second inclined block 12, and the outer wall of the fixing ring 10 is fixedly connected to a base 13.
[0031] Among them, Figure 4 As shown, the base 13 is provided with a sliding groove that matches the limiting column 8. The limiting column 8 forms a sliding structure with the base 13 through the connecting plate 7, which is beneficial to prevent rotation when pressing the fixing plate 6, and plays an effect of stabilizing the direction of the fixing plate 6.
[0032] Among them, Figure 4 As shown, the fixed ring 10 is provided with a sliding groove that matches the sliding column 9. The sliding column 9 forms a sliding structure with the fixed ring 10 through the fixed plate 6, which is conducive to the sliding column 9 pushing the second inclined block 12 to slide and lift the first inclined block 2 to provide power.
[0033] Among them, Figure 4 As shown, the base 13 is provided with a sliding groove that matches the second inclined block 12. The second inclined block 12 and the base 13 form a sliding structure through the sliding column 9, which is conducive to enabling the second inclined block 12 to contact with the first inclined block 2, preventing the second inclined block 12 from sliding out of the contact surface with the first inclined block 2, and controlling the sliding distance of the second inclined block 12.
[0034] During use: first, the user manually pushes the fixed plate 6 to make the limiting column 8 slide in the sliding groove of the base 13, limit the position of the fixed plate 6 and prevent rotation, and realize that the handle 5 pushes the sliding column 9 to slide and slide in the groove of the fixed ring 10. At the same time, the sliding column 9 drives the second inclined block 12 to move in the groove of the base 13, so that the inclined surface of the second inclined block 12 contacts the inclined surface of the first inclined block 2. Pushing forward will change the position of the first inclined block 2, so that the first inclined block 2 drives the sliding block 3 and the top plate 4 to move downward, so that the top plate 4 demolds the foam on the inner wall of the mold 1, which can prevent the foam from adhering to the inner wall of the mold 1 and reduce the operation time of the workers.
