Description

Technical Field

[0001] This invention relates to a rapid prototyping tooling, and more particularly to a rapid prototyping tooling for metal furniture casting, belonging to the field of metal casting technology. Background Technology

[0002] In the field of metal furniture manufacturing, especially in the casting of metal parts with complex shapes and fine textures such as carved handles, traditional casting tooling has many shortcomings. On the one hand, it is not convenient to operate, the mold opening and closing process is cumbersome, manual operation is difficult and labor-intensive, and it relies heavily on manual placement and removal of castings, which is inefficient and cannot meet the needs of large-scale production.

[0003] On the other hand, the cooling effect is not ideal. Traditional tooling lacks an effective cooling system, and the heat dissipation of the mold and casting is slow, resulting in a long casting cycle and difficulty in improving production efficiency. At the same time, demolding is difficult. For complex-shaped carved handles that fit tightly with the mold, the casting is easily damaged during demolding, resulting in a low yield.

[0004] Therefore, it is urgent to improve the tooling for metal furniture casting in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid prototyping tooling for metal furniture casting. After molten metal is injected into the lower mold cavity, the upper pressure plate of the tooling is pushed to make the upper module penetrate into the lower mold cavity and be pressed into shape. A water pump is connected through a water supply pipe to form a cooling medium circulation system, which improves cooling efficiency, shortens the casting cycle, and improves production efficiency. The radial hole protrusion can push the casting upward to achieve demolding. At the same time, when the hollow push rod moves slightly upward, it can inflate the lower mold cavity with air, further reducing the heat of the casting and facilitating rapid prototyping.

[0009] Preferably, the pressure plate rotation mechanism includes a dual-output shaft motor and a guide limiting plate. The dual-output shaft motor is fixedly disposed on one side of the outer side of the tooling base, and the guide limiting plate is disposed on the output shaft of the dual-output shaft motor through a limiting plate connector. The tooling upper pressure plate is provided with symmetrically distributed pressure plate brake ears. The pressure plate brake ears are fixedly installed on the upper side of the pressure plate rotation mechanism by electric telescopic rods. The guide limiting plate is provided with upper module limiting holes corresponding to the upper module. When the electric telescopic rod is braked downwards, the upper pressure plate of the tooling is used to push the upper module downwards and penetrate into the interior of the lower mold cavity through the upper module limiting hole; The upper module is provided with an exhaust port.

[0010] Preferably, the upper side of the tooling base is provided with a plurality of electromagnet assemblies, and the electromagnet assemblies are located on one side of the dual-output shaft motor; The electromagnet assembly includes an iron core and a coil wound around the iron core. The coil is electrically connected to an external power source through a wire. When the coil is energized, the electromagnet assembly is used to attract the pressure plate rotation mechanism. An electromagnet housing is fixedly installed on the outer side of the conductor coil.

[0011] Preferably, the outer side of the tooling base is provided with symmetrically distributed base rotation support blocks, and the base rotation support blocks are located below the electromagnet assembly; A base rotation motor is fixedly installed between the two base rotation support blocks. The base rotation support blocks are fixedly installed at the output end of the base rotation motor. The base rotation motor is used to rotate the tooling base.

[0012] Preferably, a support base is fixedly connected to the bottom of the base rotary motor, the base rotary motor is fixedly disposed in the middle of the support base, a plurality of support columns 1 are provided on the upper side of one side of the support base, the tooling base is placed on the support columns 1, a plurality of support columns 2 are provided on the upper side of the other side of the support base, and a collection box is placed on the support columns 2.

[0013] Preferably, a cooling pad is fixedly provided in the middle of the collection box, and heat dissipation fins are provided on the bottom side of the collection box.

[0015] Preferably, a water tank is fixedly installed on the upper side of the support base, the water tank is filled with water, the water tank is located on one side of the tooling base, and the water pump is located inside the water tank.

[0016] This invention has at least the following beneficial effects: 1. After the molten metal is injected into the lower mold cavity, the upper pressure plate of the tooling is pushed to make the upper module penetrate into the lower mold cavity and be pressed into shape. A water pump is connected through the water supply pipe to form a cooling medium circulation system, which improves cooling efficiency, shortens the casting cycle, and improves production efficiency. The radial hole protrusion can push the casting upward to achieve demolding. At the same time, when the hollow push rod moves slightly upward, it can inflate the lower mold cavity with air, further reducing the heat of the casting and helping to form quickly.

[0017] 2. After the hydraulic rod on the braking mechanism is activated, the hollow push rod moves upward through the brake arm. The top of the hollow push rod will slightly squeeze the casting, loosening it. Then the radial hole protrudes to the upper side of the through hole. Gas pressure is used to assist in demolding, making the demolding process smoother, reducing damage to the casting, and improving the yield.

[0018] 3. When the electric telescopic rod brakes downwards, the upper pressure plate of the tooling pushes the upper module downwards and penetrates into the lower mold cavity through the upper module's limiting hole. This allows for precise clamping of the upper module, ensuring the mold's sealing and stability during the casting process. Simultaneously, the vent holes on the upper module help expel gas from the mold, preventing defects such as porosity in the casting and improving casting quality. To enhance the stability of the upper module during die casting, the electromagnet assembly strengthens the overall stability of the tooling, preventing displacement of the pressure plate rotation mechanism due to external forces or vibrations. This ensures accurate fit between the upper module and the lower mold cavity, further improving casting precision and product quality. Attached Figure Description

Detailed Implementation

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figures 1-8 As shown, the rapid prototyping tooling for metal furniture casting provided in this embodiment includes a tooling base 1 and a tooling upper pressure plate 2. The tooling upper pressure plate 2 is rotatably mounted on one side of the tooling base 1 via a pressure plate rotation mechanism 4. The tooling base 1 and the tooling upper pressure plate 2 are rotatably mounted via the pressure plate rotation mechanism 4, allowing the tooling upper pressure plate 2 to rotate flexibly, facilitating opening and closing operations during the casting process, making it easy to place and remove castings, improving the convenience and flexibility of operation, and reducing the difficulty and labor intensity of manual operation. The upper side of the tooling base 1 has multiple lower mold cavities 101, and the interior of the lower mold cavities 101 is... The tooling has a through hole 1011 and multiple upper modules 201 corresponding to the lower mold cavity 101 are provided on the lower side of the upper pressure plate 2. When the mold is opened, the upper pressure plate 2 is rotated open by the pressure plate rotation mechanism 4, and the molten metal is injected into the lower mold cavity 101. After the injection is completed, the pressure plate rotation mechanism 4 is restarted to rotate the upper pressure plate 2 back to its original position and push the upper pressure plate 2 downward so that the upper modules 201 penetrate into the lower mold cavity 101, thereby achieving the pressing and forming of the molten metal. The structure is simple, and the multi-cavity design can realize the casting of multiple carved handles at one time, which improves production efficiency and meets the needs of large-scale production. To achieve rapid prototyping of castings: First, after the molten metal is injected into the lower mold cavity 101, the upper pressure plate 2 of the tooling is pushed downward, so that the upper module 201 goes deep into the lower mold cavity 101 to achieve the pressing and forming of the molten metal. Then, the tooling base 1 has a water storage tank 102 and a braking tank 103 inside. The water storage tank 102 has multiple flow channels 1021 inside, and the flow channels 1021 are located around the lower mold cavity 101. The water storage tank 102 is connected to a water pump 8 through a water supply pipe 801. The tooling base 1 has a water storage tank 102 inside, with multiple flow channels 1021 inside and located around the lower mold cavity 101. The water pump 8 is connected through a water supply pipe 801. During the casting process, the water pump 8 can deliver water to the inside of the water storage tank 102. The water flows in the flow channels 1021, which can quickly remove the heat from the mold and casting, improve cooling efficiency, shorten the casting cycle, and thus improve production efficiency. Moreover, the water supply pipe 801 includes an inlet pipe and a drain pipe. The inlet pipe is connected to the water pump 8 to form a cooling medium circulation system, which can ensure that the cooling water continuously and effectively cools the mold, achieving rapid molding of the casting. At the same time, it facilitates centralized treatment and reuse of the cooling water, reducing production costs. Finally, a braking mechanism 3 is fixedly installed inside the braking chamber 103. The braking mechanism 3 includes a braking plate 302 and multiple hydraulic rods 301. The braking plate 302 is located at the output end of the hydraulic rods 301. Multiple hollow push rods 304 are provided on the braking plate 302. The hollow push rods 304 pass through the braking chamber 103 and the water storage chamber 102 in sequence and extend into the interior of the lower mold cavity 101. Multiple radial holes 3041 connected to the interior of the hollow push rod 304 are opened at the upper end of the hollow push rod 304. When the hollow push rod 304 moves upward, the radial holes 3041 protrude to the upper side of the through hole 1011 to push the casting upward and introduce gas. It can both push the casting upward to achieve demolding and introduce gas. That is to say, when the hollow push rod 304 moves slightly upward, the radial holes 3041 on the hollow push rod 304 penetrate into the interior of the lower mold cavity 101 and fill the interior of the lower mold cavity 101 with gas, thereby further reducing the heat of the casting and achieving the purpose of rapid molding. Therefore, after the molten metal is injected into the lower mold cavity 101, the upper pressure plate 2 of the tooling is pushed to make the upper module 201 penetrate into the lower mold cavity 101 and be pressed into shape. The water pump 8 is connected through the water pipe 801 to form a cooling medium circulation system, which improves cooling efficiency, shortens the casting cycle, and improves production efficiency. The radial hole 3041 protrudes and can push the casting upward to achieve demolding. At the same time, when the hollow push rod 304 moves slightly upward, it can inflate the lower mold cavity 101 with air, further reducing the heat of the casting and helping to form quickly. Of course, when the hollow push rod 304 moves upward, in addition to rapidly cooling the casting through the radial hole 3041, it also helps to quickly demold the casting. The brake plate 302 is provided with multiple brake arms 303 corresponding to the lower mold cavity 101. The hollow push rod 304 is fixedly mounted on the brake arm 303. The lower mold cavity 101 is connected to the interior of the brake chamber 103 through the radial hole 3041. After the hydraulic rod 301 on the brake mechanism 3 is activated, the hollow push rod 304 is driven to move upward through the brake arm 303. The top of the hollow push rod 304 will slightly squeeze the casting, making the casting loose. Then the radial hole 3041 protrudes to the upper side of the through hole 1011. Gas pressure is used to assist demolding, making the demolding process smoother, reducing damage to the casting, and improving the yield. Meanwhile, in order to ensure the sealing of the lower mold cavity 101 during casting, when the hollow push rod 304 moves downward, the upper side of the hollow push rod 304 is flush with the upper side of the through hole 1011, thus ensuring the sealing during casting.

[0023] Furthermore, such as Figure 1 and Figure 6 As shown, in order to introduce gas into the lower mold cavity 101 through the radial hole 3041, an air pump chamber 105 is fixedly installed on the tooling base 1. The air pump chamber 105 is connected to the interior of the brake chamber 103. An air pump 9 is fixedly installed inside the air pump chamber 105. After the air pump 9 is started, the airflow enters the lower mold cavity 101 through the radial hole 3041. The air pump 9 further enhances the gas pressure during demolding, ensuring that the casting can be smoothly removed from the mold. Especially for some complex-shaped carved handles that fit tightly with the mold, this design can effectively solve the problem of demolding difficulty.

[0024] Furthermore, to facilitate mold making, such as Figure 1 and Figure 4 As shown, the pressure plate rotation mechanism 4 includes a dual-output shaft motor 402 and a guide limiting plate 401. The dual-output shaft motor 402 is fixedly installed on one side of the outer side of the tooling base 1. The guide limiting plate 401 is installed on the output shaft of the dual-output shaft motor 402 through the limiting plate connector 403. The guide limiting plate 401 can accurately control the rotation angle and position of the pressure plate 2 on the tooling, ensuring the stability and accuracy of the pressure plate 2 on the tooling during the rotation process, facilitating the accurate correspondence between the upper module 201 and the lower mold cavity 101, and improving the casting accuracy. Furthermore, the upper pressure plate 2 of the tooling is provided with symmetrically distributed pressure plate brake ears 202. The pressure plate brake ears 202 are fixedly installed on the upper side of the pressure plate rotation mechanism 4 via an electric telescopic rod 203. The guide limit plate 401 is provided with an upper module limit hole 4011 corresponding to the upper module 201. When the electric telescopic rod 203 brakes downward, the upper pressure plate 2 of the tooling is used to push the upper module 201 downward and penetrate into the lower mold cavity 101 through the upper module limit hole 4011. The upper module 201 is provided with an exhaust hole. When the electric telescopic rod 203 brakes downward, the upper pressure plate 2 of the tooling pushes the upper module 201 downward and penetrates into the lower mold cavity 101 through the upper module limit hole 4011. This can achieve precise clamping of the upper module 201, ensuring the sealing and stability of the mold during the casting process. At the same time, the exhaust hole on the upper module 201 helps to discharge the gas in the mold, prevent defects such as porosity in the casting, and improve the quality of the casting. In addition, to improve the stability of the upper module 201 during the die-casting process, such as Figure 1 As shown, multiple electromagnet assemblies 5 are arranged on the upper side of the tooling base 1. The electromagnet assemblies 5 are located on one side of the dual-output shaft motor 402. Each electromagnet assembly 5 includes an iron core 501 and a coil 502 wound around the iron core 501. The coil 502 is electrically connected to an external power source through a wire. When the coil 502 is energized, the electromagnet assembly 5 is used to attract the pressure plate rotation mechanism 4. An electromagnet housing 503 is fixedly arranged on the outer side of the coil 502. During the casting process, the electromagnet assembly 5 can enhance the overall stability of the tooling, prevent the pressure plate rotation mechanism 4 from being displaced due to external force or vibration, ensure the accurate fit between the upper module 201 and the lower mold cavity 101, and further improve the casting accuracy and product quality.

[0025] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the outer side of the tooling base 1 is provided with symmetrically distributed base rotation support blocks 104. The base rotation support blocks 104 are located below the electromagnet assembly 5. A base rotation motor 6 is fixedly installed between the two base rotation support blocks 104. The base rotation support blocks 104 are fixedly installed at the output end of the base rotation motor 6. The base rotation motor 6 is used to rotate the tooling base 1, so that the tooling can be rotated and adjusted as needed during the casting process. For example, when collecting castings, the tooling base 1 is rotated by the base rotation motor 6, and the castings can be demolded and collected without contact. The tilt angle makes it easier to collect the castings by utilizing their weight, thus improving the flexibility and applicability of the tooling.

[0026] Finally, as Figure 2 and Figure 3As shown, a support base 7 is fixedly connected to the bottom of the base rotary motor 6. The base rotary motor 6 is fixedly set in the middle of the support base 7. Multiple support columns 1 701 are set on the upper side of one side of the support base 7. The tooling base 1 is placed on the support column 1 701. Multiple support columns 2 703 are set on the upper side of the other side of the support base 7. A collection box 702 is placed on the support column 2 703, providing a stable support platform for the tooling base 1 and the collection box 702, ensuring the stability and safety of the entire device during operation. A cooling pad 10 is fixedly installed in the middle of the collection box 702, and heat dissipation fins 7021 are provided on the bottom side of the collection box 702. When collecting castings, the cooling pad 10 and heat dissipation fins 7021 can accelerate the cooling of the castings, further shorten the production cycle, and facilitate the centralized collection and management of castings, thereby improving production efficiency. A water tank 11 is fixedly installed on the upper side of the support base 7. The water tank 11 is filled with water and is located on one side of the tooling base 1. A water pump 8 is located inside the water tank 11. During the casting process, the water pump 8 can transport the water in the water tank 11 to the water storage tank 102. The water flows in the flow channel 1021, which can quickly remove the heat from the mold and casting and improve the cooling efficiency.
