The mold 6 is blown to increase the air flow rate around the lower mold 5 and the upper mold 6, so that the cooling speed of the wax mold inside the lower mold 5 and the upper mold 6 becomes faster, and then the first rotating shaft 2 can be controlled to drive the lower mold 5 and the upper mold 6 to rotate to the position of the corresponding material taking component to take out the wax mold. By setting a plurality of connecting rods 3 to drive the plurality of lower molds 5 and the upper mold 6 to rotate, and through the structural design of the injection component, the material taking component and the blowing blade 13, the function of batch production of wax molds is realized, which effectively solves the problem that the traditional production is to cast the wax mold, take out the wax mold after the casting is completed and cooling, and then cast the next wax mold, but the production efficiency of this method is low, which affects the production efficiency of the wax mold.

[0034] like Figure 1 As shown, the injection assembly includes a fourth support frame 22; a heating groove 23 is fixedly connected to the side wall of the fourth support frame 22; the heating groove 23 is arranged at a position corresponding to the top of the fourth support frame 22; the discharge port of the heating groove 23 is arranged corresponding to the injection port 601; a solenoid valve is installed at the discharge port of the heating groove 23; a heater is installed inside the heating groove 23; during operation, when it is necessary to inject wax liquid into the lower mold 5 and the upper mold 6, the wax block raw material can be first put into the heating groove 23, and the wax block can be heated by the heater inside the heating groove 23. The heater can be heated by a resistance wire to melt the wax block into wax liquid, and then the solenoid valve can be controlled to open. The solenoid valve is an automatic valve that uses electromagnetic force to control the flow of fluid, so that the wax liquid is injected into the lower mold 5 and the upper mold 6, thereby making the injection of wax liquid more convenient.

[0035] like Figure 4 , Figure 5 and Fig. 9As shown, a knocking rod 24 is fixedly connected to the bottom of the lower mold 5; a support rod 25 is fixedly connected to the top of the blowing blade 13; a pull rope 26 is fixedly connected to the side wall of the support rod 25; a knocking ball 27 is fixedly connected to the bottom end of the pull rope 26; the knocking rod 24 and the knocking ball 27 are arranged correspondingly; during operation, during the rotation of the blowing blade 13, the knocking ball 27 is affected by the centrifugal force and will expand to the outside of the blowing blade 13, so that the knocking ball 27 can knock on the side wall of the knocking rod 24, causing the inside of the knocking rod 24 to vibrate, and then the bubbles in the wax liquid inside the lower mold 5 and the upper mold 6 can rise through the vibration, so that the bubbles in the wax liquid can be discharged, effectively avoiding the situation where the bubbles are easily affected by the quality of the wax model.

[0036] like Figure 1 and Figure 8 As shown, a fifth support frame 28 is fixedly connected to the side of the operating body 1; a sliding block 291 is slidably connected inside the fifth support frame 28; a sponge block 29 is fixedly connected to the bottom of the sliding block 291; a filling pipe 30 is connected to the top of the fifth support frame 28; a through hole is opened inside the sliding block 291, and the through hole is opened at a position corresponding to the end of the filling pipe 30 and the sponge block 29; during operation, after the wax mold inside the lower mold 5 and the upper mold 6 is taken out, the connecting rod 3 can be controlled to drive the lower mold 5 and the upper mold 6 to rotate to the bottom position of the corresponding sponge block 29 respectively and then stop, and the sliding block 291 is controlled to descend, so that the sponge block 29 contacts the side walls of the lower mold 5 and the upper mold 6, and then the release agent is applied to the inside of the lower mold 5 and the upper mold 6 through the sponge block 29, so that the application of the release agent inside the lower mold 5 and the upper mold 6 is more convenient, and at the same time, the release agent can be injected into the inside of the sponge block 29 through the filling pipe 30 to replenish the release agent inside the sponge block 29.

[0037] like Figure 5 and Figure 7 As shown, a plurality of grooves 31 are provided at the bottom of the lower mold 5, and the grooves 31 are regularly arranged in a linear array at the bottom of the lower mold 5; a plurality of engaging blocks 311 are fixedly connected to the top of the pushing block 15; the engaging blocks 311 are arranged corresponding to the grooves 31; during operation, when air is blown by the blowing blades 13 to cool the wax liquid inside the lower mold 5 and the upper mold 6, the grooves 31 are provided at the bottom of the lower mold 5, so that the contact area between the lower mold 5 and the air can be made larger, so that the heat dissipation speed can be faster, and at the same time, through the engagement of the engaging blocks 311 with the grooves 31, the friction between the pushing block 16 and the pushing block 15 can be made larger, so that the pushing block 15 can push the pushing block 16 more stably.

[0038] like Figure 3As shown, a liquid guide groove 32 is provided on the top of the upper mold 6; the liquid guide groove 32 is provided at a position corresponding to the injection port 601; during operation, when it is necessary to inject wax liquid into the lower mold 5 and the upper mold 6 through the injection port 601, by providing the liquid guide groove 32 on the top of the upper mold 6, the wax liquid can flow into the injection port 601 more accurately.

[0039] like Figure 6 As shown, a guide rod 33 is fixedly connected to the interior of the lower mold 5; the second limit block 17 is slidably connected to the guide rod 33; during operation, when the second limit block 17 slides inside the lower mold 5, the sliding of the second limit block 17 can be restricted by setting the guide rod 33 inside the lower mold 5, so that the push block 16 and the second limit block 17 can slide more stably.

[0040] like Figure 4 and Fig. 9 As shown, a positioning block 34 is fixedly connected to the side wall of the second rotating shaft 12; the positioning block 34 is rotatably connected to the internal position of the first support frame 9; during operation, when the first rotating shaft 2 rotates inside the first support frame 9, the rotation of the positioning block 34 is restricted by the first support frame 9, so that the second rotating shaft 12 is less likely to tilt during rotation, and the rotation of the second rotating shaft 12 is more stable.

[0041] like Fig. 9 As shown, a plurality of anti-wear rollers 35 are provided between the first support frame 9 and the positioning block 34; the side walls of the anti-wear rollers 35 are in contact with the side walls of the first support frame 9 and the positioning block 34; during operation, when the positioning block 34 rotates inside the first support frame 9, by providing the anti-wear rollers 35 between the first support frame 9 and the positioning block 34, the sliding friction between the first support frame 9 and the positioning block 34 can be converted into rolling friction, so that the friction force between the first support frame 9 and the positioning block 34 is smaller, thereby reducing the wear between the first support frame 9 and the positioning block 34.

[0042] During operation, when it is necessary to perform wax injection processing on the wax mold, the driving gear 8 can be controlled to rotate first, so that the driving gear 8 drives the driven gear 7 to rotate, so that the first rotating shaft 2 drives the connecting rod 3 to rotate, and then the connecting rod 3 drives the lower mold 5 and the upper mold 6 to rotate to the position of the corresponding injection assembly, and then the wax liquid is injected into the lower mold 5 and the upper mold 6 through the injection port 601. After that, the first rotating shaft 2 can be controlled to drive the lower mold 5 and the upper mold 6 to rotate to the internal position of the first supporting frame 9, and the second rotating shaft 12 can be controlled to drive the blowing blade 13 to rotate, so as to blow air to the lower mold 5 and the upper mold 6 to increase the air around the lower mold 5 and the upper mold 6. The air flow rate makes the wax mold inside the lower mold 5 and the upper mold 6 cool faster, and then the first rotating shaft 2 can be controlled to drive the lower mold 5 and the upper mold 6 to rotate to the position of the corresponding material removal component to take out the wax mold. By setting up multiple connecting rods 3 to drive multiple lower molds 5 and upper molds 6 to rotate, and through the structural design of the injection component, the material removal component and the blowing blade 13, the function of batch production of wax molds is realized, which effectively solves the problem of traditional production that the wax mold is cast, and after the casting is completed and cooled, the wax mold is taken out, and then the next wax mold is cast and produced. However, the production efficiency of this method is low, which affects the production efficiency of the wax mold.

[0043] When the wax mold needs to be taken out, the first rotating shaft 2 can be controlled to drive the lower mold 5 and the upper mold 6 to rotate. When the upper mold 6 passes through the hook 20, the hook 20 will hook the pull rod 21. Then, when the lower mold 5 and the upper mold 6 continue to rotate, the upper mold 6 can be turned over. Then, after the lower mold 5 and the upper mold 6 rotate to the position corresponding to the bottom of the pushing block 15, the first rotating shaft 2 can be controlled to stop rotating. Then, the pushing block 15 can be controlled to slide upward through the electric push rod to push the pushing block 16, so that the pushing block 16 pushes the wax mold up, so that the wax mold is separated from the lower mold 5. At this time, the wax mold can be taken out using a robot, so that the removal of the wax mold can be more convenient.

[0044] When it is necessary to inject wax liquid into the lower mold 5 and the upper mold 6, the wax block raw material can be first put into the heating tank 23, and the wax block can be heated by the heater inside the heating tank 23. The heater can be heated by a resistance wire to melt the wax block into wax liquid. Thereafter, the solenoid valve can be controlled to open. The solenoid valve is an automatic valve that uses electromagnetic force to control the flow of fluid, so that the wax liquid can be injected into the lower mold 5 and the upper mold 6, thereby making the injection of the wax liquid more convenient.

[0045] During the rotation of the blowing blade 13, the knocking ball 27 is affected by the centrifugal force and will expand to the outside of the blowing blade 13, so that the knocking ball 27 can knock on the side wall of the knocked rod 24, causing the inside of the knocked rod 24 to vibrate, and then the bubbles in the wax liquid inside the lower mold 5 and the upper mold 6 can rise through the vibration, so that the bubbles in the wax liquid can be discharged, effectively avoiding the situation where the bubbles are easily affected by the quality of the wax model.

[0046] After the wax molds inside the lower mold 5 and the upper mold 6 are taken out, the connecting rod 3 can be controlled to drive the lower mold 5 and the upper mold 6 to rotate to the bottom position of the corresponding sponge block 29 and then stop, and the sliding block 291 can be controlled to descend, so that the sponge block 29 contacts the side walls of the lower mold 5 and the upper mold 6, and then the release agent is applied to the inside of the lower mold 5 and the upper mold 6 through the sponge block 29, making the application of the release agent inside the lower mold 5 and the upper mold 6 more convenient. At the same time, the release agent can be injected into the interior of the sponge block 29 through the filling pipe 30 to replenish the release agent inside the sponge block 29.

[0047] When air is blown through the blowing blades 13 to cool the wax liquid inside the lower mold 5 and the upper mold 6, a groove 31 is opened at the bottom of the lower mold 5, so that the contact area between the lower mold 5 and the air can be larger, and the heat dissipation rate can be faster. At the same time, through the engagement of the engagement block 311 with the groove 31, the friction between the push block 16 and the pushing block 15 can be made greater, so that the pushing block 15 can push the push block 16 more stably.

[0048] When it is necessary to inject wax liquid into the lower mold 5 and the upper mold 6 through the injection port 601 , by providing a liquid guide groove 32 at the top of the upper mold 6 , the wax liquid can flow into the injection port 601 more accurately.

[0049] When the second limit block 17 slides inside the lower mold 5, the sliding of the second limit block 17 can be restricted by setting a guide rod 33 inside the lower mold 5, so that the push block 16 and the second limit block 17 can slide more stably.

[0050] When the first rotating shaft 2 rotates inside the first supporting frame 9, the first supporting frame 9 limits the rotation of the positioning block 34, so that the second rotating shaft 12 is less likely to tilt during rotation, and the rotation of the second rotating shaft 12 is more stable.

[0051] When the positioning block 34 rotates inside the first support frame 9, by providing an anti-wear roller 35 between the first support frame 9 and the positioning block 34, the sliding friction between the first support frame 9 and the positioning block 34 can be converted into rolling friction, so that the friction force between the first support frame 9 and the positioning block 34 is smaller, thereby reducing the wear between the first support frame 9 and the positioning block 34.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
