[0002] During the preparation of the learning machine, the outer shell and the internal electrical components are combined. In order to speed up the preparation of the outer shell of the learning machine, a mold is needed for molding.

[0003] When using the existing mold, the object is placed between the molds and the shell of the learning machine is quickly formed by die casting. During the stamping process, the mold will be tightly attached to the inside of the mold, resulting in certain disadvantages when demolding;

[0004] In order to overcome the defects of the rapid demoulding process, a secondary ejection die-casting mold for automobile parts production is disclosed with reference to the prior art (publication number CN116618605B, publication date 2023-09-19). When the die-casting mold is in use, the secondary mold plate and the primary mold plate are sequentially contracted during the downward movement of the dislocation component provided, so that demoulding is formed between the secondary mold plate and the primary mold plate and the groove on the inner wall of the hollow casting;

[0005] Although the above device can eject the objects inside the mold, during the stamping process, the metal sheet will generate a certain amount of heat during the forming process, which will cause the formed metal sheet to be hot and make it inconvenient for the staff to remove the formed parts.

[0006] Therefore, we proposed that the mold of the learning machine shell can solve the above problems well. Utility Model Content

[0007] The purpose of the present utility model is to provide a mold for the outer shell of a learning machine, so as to solve the problem proposed in the above background technology that the molds currently on the market can eject objects inside the mold, but in the process of stamping, the metal sheet will generate a certain amount of heat during the forming process, which will cause the formed metal sheet to have heat, making it inconvenient for the staff to remove the formed parts.

[0008] To achieve the above object, the utility model provides the following technical solution: a mold for a learning machine housing, comprising a lower mold, an upper mold is arranged above the lower mold, and connecting sleeves are fixed at the corners of the upper mold;

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-6 , the utility model provides the following technical solutions:

[0030] Example 1: In order to form the shell of the learning machine, please refer to the attached Figure 1 -Attached Figure 3 , comprising a lower mold 1, an upper mold 2 is arranged above the lower mold 1, and connecting sleeves 3 are fixed at the corners of the inner position of the upper mold 2; further comprising: the inner sliding of the connecting sleeve 3 is arranged on the outer side of the guide sleeve 4, and the bottom of the guide sleeve 4 is fixed to the top position of the lower mold 1, a group of buffer members 5 are fixed on both sides of the bottom of the upper mold 2, and a groove 7 is opened on the top of the lower mold 1 to facilitate the molding of the molded part 6;

[0031] When using the mold, the lower mold 1 is first fixed, and then the material is placed above the groove 7 (the shape of the forming groove is not drawn in the accompanying drawings) opened on the top of the lower mold 1. At this time, the upper mold 2 and the connecting sleeve 3 are lowered at the top position of the lower mold 1 through the guide sleeve 4 through the stamping process, and the mold of the upper mold 2 is stamped and formed on the object, so that the object is formed by the upper mold 2, thereby forming a learning machine shell;

[0032] Example 2: In order to facilitate the demoulding of the molded part 6, please refer to the attached Figure 1 -Attached Figure 6 The demolding mechanism includes a connecting rod 803, the top of which is fixed to the bottom center of the movable plate 9. A set of support rods 10 are rotatably connected to both sides of the movable plate 9. The other ends of the support rods 10 are rotatably mounted to the bottom of the first vertical rod 11. The piston block 802 is shaped like a cone, wide at the top and narrow at the bottom, and its top end fits within the air inlet 8. The first vertical rod 11 forms a sliding structure between the support rods 10 and the interior of the lower mold 1. The end of the air inlet 8 extending outside the lower mold 1 is connected to the air pump.

[0033] During the demoulding process, an air pump is connected to the end of the air inlet 8 extending outward from the lower mold 1, and the air pump can be used to supply air to the inside of the air inlet 8. At this time, the gas will drive the piston block 802 to move, so that the piston block 802 drives the connecting rod 803 and the movable plate 9 to move in height. At this time, the return spring 801 will also be deformed. In addition, the connecting rod 803 can change the height of the movable plate 9 during the movement, and the movable plate 9 can drive the support rod 10 to move, so that the first vertical rod 11 and the second vertical rod 13 set at the bottom end of the support rod 10 will also rise, so that the top of the second vertical rod 13 can be demoulded.

[0034] Example 3: In order to solve the problem that the molds currently on the market can achieve the ejection of objects inside the mold, but in the process of stamping, the metal sheet will generate a certain amount of heat during the forming process, which will cause the formed metal sheet to be hot and it is not convenient for the staff to take out the formed part 6 for processing, please refer to the attached Figure 4 -Attached Figure 6 An air inlet 8 extends from the bottom of the lower mold 1. One end of the air inlet 8 extending into the interior of the lower mold 1 is connected to a demoulding mechanism, and one side of the demoulding mechanism can act on a cooling mechanism. The cooling mechanism includes a cavity opened inside the lower mold 1. A first vertical rod 11 is slidably provided inside the lower mold 1. A set of second vertical rods 13 are fixed at the top of the first vertical rod 11. A fixed spring 12 is connected to the middle of the first vertical rod 11 and the second vertical rod 13. The other end of the fixed spring 12 is fixed to the internal position of the lower mold 1. The diameter of the first vertical rod 11 is smaller than that of the second vertical rod 13, and there are holes on the outside of the second vertical rod 13 and the first vertical rod 11 and the interior of the lower mold 1 to facilitate gas circulation. The first vertical rod 11 and the second vertical rod 13 are slidably provided at the internal position of the lower mold 1. A return spring 801 is fixedly connected to the inside of the air inlet 8 , and the top of the return spring 801 is fixed to the bottom of the piston block 802 , and the top of the piston block 802 is fixed to the bottom of the connecting rod 803 .

[0035] Since the outer side of the piston block 802 can be moved to the outer side of the top of the air inlet 8, and since the piston block 802 is conical, the gas inside the air inlet 8 can flow into the cavity. At this time, during the demolding process, since the molded part 6 is in a lifted state, and the rubber ring provided on the outer side of the second vertical rod 13 will not block the flow of gas, the gas flows into between the lower mold 1 and the molded part 6, so that the gas blows and cools the molded part 6, thereby facilitating the removal of the molded part 6.

[0036] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
