Specific embodiments

[0027] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0028] Embodiment 1:

[0029] Please refer to Figures 1 to 4 As shown, this embodiment discloses a investment casting method for the production of a casing bracket, including the following steps:

[0030] Step 1: First, place the metal mold in the middle of the upper surface of the lower die plate 3 inside the box body 1. When the lifting mechanism works, lift the lower die plate 3 into the cavity 105 of the mounting plate 102. Subsequently, the hydraulic tank 6 of the lifting and lowering mechanism drives the hydraulic rod 601 to lower the upper die plate 602 to fit with the lower die plate 3 to complete mold closing.

[0031] Step 2: The wax injector 103 injects wax liquid into the mold cavity after mold closing through the injection port 104. During or just after the wax injection process, the servo motor 5 of the vibration mechanism starts, drives the rotating shaft 501 to rotate, makes the turntable 505 rotate, and the turntable 505 drives the impact plate 509 through the spherical interface 506 and the ball 507 to generate impact vibration on the second connecting rod 503 and the connected second fixing plate 504, helping the wax liquid to better fill the cavity and discharge air bubbles.

[0032] Step 3: The bidirectional drive motor 7 is started, so that the first rotating rod 701 drives the first meshing gear 702 and the second meshing gear 703 to rotate, thereby driving the second rotating rod 704 to rotate, and enabling the scraper 706 between a pair of connecting rings 705 to scrape off the excess wax along the angle of the groove 303;

[0033] Step 4: The lifting mechanism acts again. The hydraulic rod 601 drives the upper mold plate 602 to rise and open the mold. Then, the lifting mechanism lowers the lower mold plate 3. The drive motor 8 of the discharging mechanism operates, and drives the first connecting shaft 801 and the semi-gear 803 to rotate, so that the semi-gear 803 drives the gear 804 to perform intermittent movement, and enables the tooth locking plate 805 and the clamping plate 806 to clamp and push out the formed wax mold under the drive of the transmission gear 804.

[0034] Embodiment 2:

[0035] Please refer to Figures 1 to 4 As shown in the figure, this embodiment makes further supplementary explanations based on Embodiment 1, including a box body 1. A blanking groove 101 is opened on the front surface of the box body 1. An installation plate 102 is fixedly connected inside the box body 1. A wax injector 103 is fixedly connected to the upper surface of the installation plate 102. One side of the wax injector 103 is movably connected with a pouring inlet 104. A cavity 105 is opened inside the installation plate 102. A sealing mechanism is arranged on the front surface of the box body 1. A mold sealing mechanism is arranged inside the cavity 105. An adjusting mechanism is arranged on the lower surface of the installation plate 102, and the adjusting mechanism includes a lifting mechanism and a vibrating mechanism. A lifting mechanism is arranged inside the box body 1. A wax scraping mechanism is arranged on one side of the lifting mechanism. Discharging mechanisms are arranged on the left and right sides of the blanking groove 101. The blanking groove 101 opened on the front surface of the box body 1 provides a dedicated channel for the discharging of the formed wax mold, ensuring a smooth discharging process, preventing interference between the wax mold and other components of the device, and facilitating the subsequent collection and transfer of the wax mold. The installation plate 102 fixedly connected inside the box body 1, the wax injector 103 and the pouring inlet 104 fixedly connected to its upper surface form a stable wax pouring system, ensuring that the wax liquid can be accurately injected into the mold cavity. The internally opened cavity 105 provides a moving space for components such as the lower mold plate 3, enabling the orderly operation of operations such as the installation, lifting, and closing of the mold. And the sealing mechanism on the front surface of the box body 1 drives the first air rod 202 through the first air pump 201, and drives the sliding door 204 to slide along the slide rail 203 to realize the sealing of the front surface of the box body 1, effectively preventing external dust and impurities from entering the inside of the box body 1 and avoiding their contamination of the wax liquid and the mold; the mold sealing mechanism inside the cavity 105 utilizes the return springs 301 on both sides of the lower mold plate 3 to cooperate with the sealing plate 302 to realize the self-sealing of the mold and prevent the wax liquid from leaking from the periphery of the mold.

[0036] The sealing mechanism includes a mounting frame 2, which is located on the front side of the box body 1. A first air pump 201 is fixedly connected inside the mounting frame 2. A first air rod 202 is movably connected to the lower surface of the first air pump 201. Slide rails 203 are fixedly connected to the left and right sides of the box body 1. A sliding door 204 is slidably connected to the outer wall of the slide rails 203. Connecting plates 205 are fixedly connected to the left and right sides of the front surface of the sliding door 204. A rotating shaft 206 is movably connected to one side of the connecting plate 205. A connecting block 207 is movably connected to the outer wall of the rotating shaft 206, and the connecting block 207 is connected to the first air rod 202. When it is necessary to seal the box body 1, the first air pump 201 is started to drive the first air rod 202 to expand and contract. The first air rod 202 transfers power accurately to the sliding door 204 through a transmission structure composed of the connecting block 207, the rotating shaft 206 and the connecting plate 205. Under the guiding action of the slide rails 203, the sliding door 204 realizes automatic opening and closing without manual operation, which not only improves the sealing efficiency, but also can isolate the external environment in time during the casting process, prevent impurities such as dust and moisture from entering the inside of the box body 1 to contaminate the wax liquid and the mold, ensure a clean environment for investment casting, and thus improve the quality of the castings. The slide rails 203 are fixed on the left and right sides of the box body 1, providing a stable sliding track for the sliding door 204, preventing the sliding door 204 from shifting or jamming during the movement, and ensuring that it can close smoothly and accurately to achieve a tight seal.

[0037] The mold sealing mechanism includes a lower mold plate 3, which is located inside the cavity 105. Reset springs 301 are movably connected to the left and right sides of one side of the lower mold plate 3. A sealing plate 302 is fixedly connected to one side of the reset springs 301. Grooves 303 are formed in the front and rear sides of the mounting plate 102, and the grooves 303 are connected to the cavity 105. A clamping groove 304 is formed in one side of the sealing plate 302. The reset springs 301 on both sides of the lower mold plate 3 are connected to the sealing plate 302 to form an adaptive sealing structure. During the mold closing process, when the upper mold plate 602 is pressed down, the sealing plate 302 is squeezed, and the reset springs 301 are compressed and deformed, so that the sealing plate 302 closely fits the mold parting surface and the surrounding structure, effectively filling the possible gaps. Even if there are slight dimensional errors or wear in the mold, the elastic force of the reset springs 301 can ensure that the sealing plate 302 always maintains a good sealing state, preventing the wax liquid from leaking from the edge of the mold, ensuring the integrity and accuracy of the wax mold forming, and reducing the rejection rate caused by leakage. Secondly, the grooves 303 formed in the front and rear of the mounting plate 102 are connected to the cavity 105, providing a discharge channel for the excess wax material scraped by the wax scraping mechanism. During the wax scraping process, the wax knife 706 scrapes the wax material on the parting surface along the angle of the grooves 303, thus avoiding the accumulation of excess wax material affecting the mold sealing and the subsequent production process.

During the wax injection process, it can effectively promote the filling of the wax liquid into the fine parts of the mold cavity, discharge air bubbles at the same time, significantly reduce defects such as pores and shrinkage porosity inside the wax mold, improve the density and surface quality of the wax mold, and thus improve the mechanical properties and qualification rate of the casing support castings.
