Conventional molds lack a heat dissipation and cooling structure, which will lead to a long time for the mechanical parts to be formed, thereby affecting the production efficiency of mechanical parts. Therefore, it is necessary to improve its technology. Summary of the Invention

Detailed Description of the Embodiment

[0022] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0023] Refer to the attached drawings of the specification Figures 1-4, A rapid prototyping mechanical part mold, including a base 1. At the four corners of the top of the base 1, lifting columns 2 are fixedly connected. Between the tops of the lifting columns 2, a lower mold base 3 is fixedly connected. A ventilation cavity 4 is opened inside the lower mold base 3. Air inlets 5 are opened on both sides of the lower mold base 3. An air outlet 6 is opened at the middle end of the bottom of the lower mold base 3. Blowing mechanisms 7 are fixedly installed on both sides of the top of the base 1. Lubrication structures 8 are fixedly installed at the upper ends of both sides of the lower mold base 3. A support column 9 is fixedly connected to the rear end of the top of the base 1. The top of the support column 9 is fixedly connected to a top plate 10. A telescopic cylinder 11 is fixedly installed on the top of the top plate 10. The output end of the telescopic cylinder 11 passes through the top plate 10 and is fixedly connected to an upper mold base 12.

[0024] To achieve the purpose of enabling mechanical parts to be rapidly prototyped and easily demolded, the lifting columns 2 at the top of the base 1 are used to lift the lower mold base 3 so that there is space at its bottom for heat dissipation. The lower mold base 3 is filled with molten liquid. The telescopic cylinder 11 at the top of the top plate 10 works to drive the upper mold base 12 to press down and complete the mold closing with the lower mold base 3. Then the molten liquid will cool and solidify in the mold. The blowing mechanism 7 works to blow air into the air inlet 5. The air circulates inside the ventilation cavity 4 to quickly take away the heat generated when the molten liquid cools. The hot air will be discharged through the air outlet 6, thus facilitating the rapid cooling and solidification of the mechanical parts. When the mechanical parts are formed, the upper mold base 12 rises driven by the telescopic cylinder 11, and lubricating liquid is injected into the lower mold base 3 through the lubrication structure 8 to play a lubricating role, enabling the mechanical parts to separate from the inner side wall of the lower mold base 3 so that the staff can take them out.

[0025] Reference Figures 1-2 , The blowing mechanism 7 includes a connecting column 701, a mounting seat 702, and a cooling fan 703. Connecting columns 701 are fixedly connected to both sides of the top of the base 1. The top of the connecting column 701 is fixedly connected to a mounting seat 702. A cooling fan 703 is fixedly installed inside the mounting seat 702. The connecting column 701 is provided to support the mounting seat 702, and the inside of the mounting seat 702 is used to install the cooling fan 703. When the cooling fan 703 works, it can blow air into the air inlet 5 so that the air enters the ventilation cavity 4 through the air inlet 5, thereby quickly taking away the heat to cool the mechanical parts inside the lower mold base 3.

[0026] Reference Figure 2 And Figure 4 , A clamping strip 13 is fixedly connected to the outer side of the bottom of the upper mold base 12. A clamping groove 14 is opened on the outer side of the top of the lower mold base 3. The clamping strip 13 is clamped inside the clamping groove 14. By setting the clamping strip 13 and the clamping groove 14, when the upper mold base 12 descends, the clamping strip 13 will be clamped inside the clamping groove 14, thereby improving the firmness when the upper mold base 12 and the lower mold base 3 are closed and avoiding loosening at their connection.

[0027] Reference Figure 1 With Figure 3 At the top of the top plate 10, a protective cover 15 is fixedly connected to the outside of the telescopic cylinder 11. Heat dissipation openings 16 are provided on both sides of the protective cover 15. A dust-proof net 17 is fixedly connected to the inside of the heat dissipation openings 16. The protective cover 15 is provided to protect the telescopic cylinder 11 from being affected by the outside during its operation. The heat dissipation openings 16 are used to dissipate the heat inside the protective cover 15. The dust-proof net 17 is used to protect the heat dissipation openings 16 to prevent external dust and impurities from entering the inside of the protective cover 15 through the heat dissipation openings 16.

[0028] Reference Figure 1 With Figure 4 The lubrication structure 8 includes a liquid injection hole 801, a liquid guide pipe 802, and a liquid guide hopper 803. Liquid injection holes 801 are provided at the upper ends of both sides of the lower die base 3. A liquid guide pipe 802 is inserted into the inside of the liquid injection hole 801. The other end of the liquid guide pipe 802 is fixedly connected to a liquid guide hopper 803. The liquid guide hopper 803 is provided, and the lubricating liquid can be injected into the liquid guide pipe 802 through the liquid guide hopper 803. The lubricating liquid flows along the liquid guide pipe 802 and then flows out through the liquid injection hole 801. The flowing out lubricating liquid will penetrate between the mechanical parts and the lower die base 3 to provide lubrication, so that the mechanical parts can be conveniently taken out.

[0029] Reference Figure 1 At the four corners of the top of the base 1, mounting holes 18 are provided. The aperture of the mounting hole 18 is 2 cm. The mounting holes 18 are provided, and the aperture of the mounting hole 18 is set to 2 cm. A bolt of a suitable specification can be used to install it, so that the staff can install it in a suitable position for use.

[0030] Reference Figures 1-2 At the bottom of the upper die base 12, a receiving groove 19 is provided. A convex template 20 is clamped inside the receiving groove 19. At the four corners of the top of the convex template 20, screws 21 are fixedly connected. Through holes 22 are provided at the positions corresponding to the screws 21 on the top of the upper die base 12. Nuts 23 are threadedly connected to the ends of the screws 21 protruding through the through holes 22. The receiving groove 19 is provided, and the convex template 20 is clamped inside the receiving groove 19 for preliminary fixation. At the same time, the other end of the screw 21 will pass through the through hole 22, and the staff can use the nut 23 to lock the protruding end of the screw 21, so as to install the convex template 20 at the bottom of the upper die base 12. The bottom of the convex template 20 can be set into different shapes to assist in the forming of mechanical parts. In this way, the convex template 20 is convenient for disassembly and replacement.

[0031] Reference Figure 2, magnetic sheets 24 are embedded on the inner side of the accommodation groove 19 and the top of the convex template 20. The magnetic sheets 24 adsorb each other. By setting the magnetic sheets 24, when the convex template 20 is stuck inside the accommodation groove 19, the magnetic sheets 24 will adsorb each other, making it difficult for the convex template 20 to come out, so as to lock it later.

[0032] In this embodiment, the implementation scenario is as follows: When using this mold, the lifting column 2 on the top of the base 1 is used to lift the lower mold base 3 so that there is space at the bottom for heat dissipation. The molten liquid is injected into the lower mold base 3. The telescopic cylinder 11 on the top of the top plate 10 works to drive the upper mold base 12 to press down and complete the mold closing with the lower mold base 3. Then the molten liquid will cool and solidify in the mold. When the upper mold base 12 descends, the clamping strip 13 will be clamped inside the clamping groove 14, thereby improving the firmness when the upper mold base 12 and the lower mold base 3 are closed, and avoiding loosening at their connection. The convex template 20 is clamped in the accommodation groove 19 at the bottom of the upper mold base 12 for preliminary fixation. At the same time, the other end of the screw 21 will pass through the through hole 22, and the staff can use the nut 23 to lock the protruding end of the screw 21 to install the convex template 20 at the bottom of the upper mold base 12. The bottom of the convex template 20 can be set into different shapes to assist in the forming of mechanical parts. In this way, the convex template 20 is convenient for disassembly and replacement. When the convex template 20 is stuck inside the accommodation groove 19, the magnetic sheets 24 will adsorb each other, making it difficult for the convex template 20 to come out, so as to lock it later. The inside of the mounting seat 702 is used to install the cooling fan 703. When the cooling fan 703 works, it can blow air into the air inlet 5, so that the air enters the ventilation cavity 4 through the air inlet 5. The air circulates inside the ventilation cavity 4 to quickly take away the heat generated when the molten liquid cools. The hot air will be discharged through the air outlet 6, thus facilitating the rapid cooling and forming of mechanical parts. After the mechanical parts are formed, the upper mold base 12 rises driven by the telescopic cylinder 11. The staff can inject the lubricating liquid into the liquid guide pipe 802 through the liquid guide hopper 803. The lubricating liquid flows along the liquid guide pipe 802 and then flows out through the liquid injection hole 801. The flowing lubricating liquid will seep between the mechanical parts and the inner side wall of the lower mold base 3 to provide lubrication, so that the mechanical parts are separated from the inner side wall of the lower mold base 3, facilitating the staff to take them out, thus completing the demolding work.

[0033] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
