DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9 As shown, a wax mold injection molding device described in an embodiment of the present invention comprises a processing table 1, a top support table 2 is arranged above the processing table 1, a support column 12 is fixedly connected between the processing table 1 and the top support table 2, a cooling water tank 11 is opened at the top of the processing table 1, a wax output mold 22 is fixed to one side of the bottom end of the top support table 2, a wax inlet pipe 21 is fixed to the top of the top support table 2 close to the wax output mold 22, the wax output mold 22 and the wax inlet pipe 21 are connected, a plurality of molding molds 53 are arranged between the processing table 1 and the top support table 2, a steering sleeve 5 is provided on the outer sleeve of the support column 12, and the molding mold 53 matches the outer diameter of the wax output mold 22;

[0033] When making a wax model, first a molding mold 53 will move to the bottom end of the wax mold 22, and then the molding mold 53 and the wax mold 22 will be closed, and then high-temperature wax liquid can be transported to the inside of the wax mold 22 through the wax inlet pipe 21, and the high-temperature wax liquid enters the interior of the molding mold 53 through the holes inside the wax mold 22. At this time, the internal structure of the molding mold 53 can shape the wax mold. The molded wax mold is separated from the bottom of the wax mold 22 for pre-cooling, and then it is transported to the inside of the cooling water tank 11 for cooling. The inside of the wax mold is solidified by cooling, and then the prepared wax mold is removed for subsequent operations.

[0034] like Figure 3 to Figure 4As shown, a toothed disc 51 is fixed to the bottom end of the steering sleeve 5, a servo motor 6 is installed at the top of the processing table 1, an output gear 61 is fixed to the rotating shaft of the servo motor 6, and the output gear 61 is meshedly connected with the toothed disc 51. The steering sleeve 5 forms a rotating structure outside the support column 12, and the steering sleeve 5 is hinged with rotating arms 52 around it. The rotating arms 52 are evenly spaced around the steering sleeve 5, and the rotating arms 52 form a flipping structure around the steering sleeve 5. The rotating arm 52 is away from one end of the steering sleeve 5. It is movably connected to the molding mold 53; it needs to be moved during a series of operations for molding and cooling the wax mold. At this time, the servo motor 6 starts to drive the output gear 61 to rotate, and the output gear 61 engages with the toothed disc 51 to drive the steering sleeve 5 to rotate outside the support column 12. The rotation of the steering sleeve 5 drives the rotating arm 52 to rotate, and the rotating arm 52 drives the molding mold 53 to move its position, so that the working position of the molding mold 53 can be switched, and the four rotating arms 52 will rotate at the same time, so that four groups of molding molds 53 will be in different working positions at the same time.

[0035] like Figures 4 to 5 As shown, a guide hole is provided inside the rotating arm 52, and a second telescopic rod 521 is inserted inside the guide hole. The end of the second telescopic rod 521 away from the rotating arm 52 is hinged to a sliding plate 54, and a slot 541 is provided inside the sliding plate 54. The molding mold 53 is arranged above the sliding plate 54. The top of the processing table 1 is fixed with a multi-section guide rail 4, and the slot 541 is sleeved on the outside of the multi-section guide rail 4; when the steering sleeve 5 drives the sliding plate 54 to rotate, the slot 541 will slide outside the multi-section guide rail 4, and the multi-section guide rail 4 can guide the slot 541, so that the sliding plate 54 can move along the trajectory of the multi-section guide rail 4. The guide hole inside the rotating arm 52 provides a movable space for the second telescopic rod 521 when it moves to a certain position, so that the second telescopic rod 521 can move freely inside the guide hole of the rotating arm 52, and the second telescopic rod 521 is limited by the sliding plate 54 and the rotating arm 52 to prevent it from falling off from the inside of the rotating arm 52 during movement.

[0036] like Figure 3 to Figure 4As shown, the multi-section guide rail 4 includes section A, section B, section C and section D. Section A is an ascending section used to drive the molding mold 53 to fit with the wax mold 22, section B is a translation section used to transport the molding mold 53 after internal molding, section C is a descending section used to drive the molding mold 53 to sink into the cooling water tank 11, and section D is a translation section used to take out the molded wax mold; during the movement of the sliding plate 54, it will pass through different positions of the multi-section guide rail 4. First, the first molding mold 53 will be above section D. When the steering sleeve 5 rotates, the sliding plate 54 is driven to move by the rotating arm 52. At this time, the sliding plate 54 moves toward section A, and section A guides the sliding plate 54 upward. When the sliding plate 54 moves to the middle of section A, its top molding mold 53 will fit with the wax mold 22. At this time, the wax mold 22 injects high-temperature wax liquid into the interior of the molding mold 53. Then the internal wax liquid of the molding mold 53 is initially formed. The steering sleeve 5 drives the sliding plate 54 to continue to rotate. At this time, the second half of section A guides the sliding plate 54 downward. At this time, the molding mold 53 is separated from the wax mold 22. The sliding plate 54 moves to section B and the molding mold 53 is placed in the air for heat dissipation. Then the steering sleeve 5 continues to rotate and drives the sliding plate 54 to move to section C. Section C guides the sliding plate 54 to sink into the cooling water tank 11. At this time, the molding mold 53 is immersed in the cooling water tank 11 for cooling. After cooling, the steering sleeve 5 rotates to rotate the cooled molding mold 53 back to section D.

[0037] like Figure 2 and Figure 7 As shown, a limiting rod 542 is fixed to one end of the sliding plate 54 away from the second telescopic rod 521, and a limiting sleeve 56 is sleeved on the outside of the limiting rod 542, and a slider 561 is fixed to the top and bottom ends of the limiting sleeve 56. A guide slot 23 is opened inside the top support platform 2, and the inner diameter of the guide slot 23 matches the limiting sleeve 56 and the slider 561, and the limiting sleeve 56 forms a sliding structure inside the guide slot 23; when the slot 541 slides outside the multi-section guide rail 4, its movement stability needs to be ensured. At this time, the limiting rod 542 at one end of the sliding plate 54 will drive the limiting sleeve 56 to follow the limiting rod 542 to slide inside the guide slot 23. Due to the restriction of the limiting sleeve 56, the limiting rod 542 can remain stable, and the limiting rod 542 can limit the sliding plate 54 to keep it in a vertical stable state, and the slider 561 limits the limiting sleeve 56 inside the guide slot 23.

[0038] like Figure 5 to Figure 6As shown, a connecting seat 55 is fixed to the top of the sliding plate 54, and both ends of the connecting seat 55 are sleeved with flip blocks 551. The top of the flip block 551 is fixedly connected to the molding mold 53, and a coil spring 552 is fixed between the connecting seat 55 and the flip block 551. A support frame 532 is fixed to one side of the sliding plate 54. The molding mold 53 forms a flip structure at the top of the sliding plate 54 through the connecting seat 55 and the flip block 551; the connecting seat 55 and the flip block 551 can support the molding mold 53 above the sliding plate 54, and the tension of the coil spring 552 can flip the flip block 551 to make it close to the support frame 532. The support frame 532 supports one end of the molding mold 53 to keep the molding mold 53 in a stable state.

[0039] like Figure 2 and Figure 8 As shown, a through hole is opened inside the top support platform 2, and an air duct 3 is arranged above the through hole. A fan 31 is installed inside the air duct 3, and an air inlet duct 32 is fixed on the side of the air duct 3 close to the B section of the multi-section guide rail 4, and an exhaust duct 33 is fixed on the side of the air duct 3 close to the D section of the multi-section guide rail 4. The air inlet duct 32 and the exhaust duct 33 are fixed inside the through hole of the top support platform 2; when the forming mold 53 enters the B section, it will stay under the air inlet duct 32, and the forming mold 53 at the other end will stay under the exhaust duct 33. At this time, the fan 31 exhausts air from the inside of the air duct 3, and the air inlet duct 32 sucks in air, and the air around the forming mold 53 below the air inlet duct 32 is sucked in, and at the same time, heat will also enter the inside of the air inlet duct 32 along with the airflow, and at the same time, air will be blown out from one end of the exhaust duct 33, and the air can dry the surface of the forming mold 53 below the exhaust duct 33, which can make it more convenient to remove the wax model later.

[0040] like Figures 8 to 9 The cam 342 is pressed against the top of the support frame 532 to release the first spring 341, and the cam 343 is pressed against the bottom of the support frame 532 to release the first spring 341.

[0041] like Figures 8 to 9As shown, the tipping rod 34 is symmetrically distributed about the vertical center line of the exhaust pipe 33, and the first telescopic rod 342 forms a telescopic structure inside the telescopic hole of the tipping rod 34 through the return spring 341; the position of the tipping rod 34 corresponds to the docking groove 531, and the first telescopic rod 342 can be automatically adjusted inside the tipping rod 34 according to the distance between the bottom of the tipping rod 34 and the molding mold 53.

[0042] like Figure 5 and Fig. 9 As shown, the docking block 343 engages with the docking groove 531 to drive the forming mold 53 to flip, and the support frame 532 can support the forming mold 53; the forming mold 53 is flipped by the thrust of the docking block 343, and the support frame 532 supports the bottom of the forming mold 53 to keep it stable.

[0043] Working principle: During the injection molding process, the wax inlet pipe 21 is connected to the external high-temperature wax liquid pipeline, and then the servo motor 6 is started to drive the toothed disc 51 to rotate through the output gear 61, and the toothed disc 51 drives the steering sleeve 5 to rotate. At this time, the rotating arm 52 drives the sliding plate 54 to rotate, which makes the card slot 541 slide on the outside of the multi-section guide rail 4. The multi-section guide rail 4 can guide the card slot 541, so that the sliding plate 54 can move along the trajectory of the multi-section guide rail 4. During the movement of the sliding plate 54, it will pass through different positions of the multi-section guide rail 4. First, the first molding mold 53 will be above the D section. When the steering sleeve 5 rotates, the sliding plate 54 is driven to move by the rotating arm 52. At this time, the sliding plate 54 moves toward the A section, and the A section guides the sliding plate 54 upward. When the sliding plate 54 moves to the middle of the A section, its top molding mold 53 will be closed with the wax outlet mold 22. At this time, the wax outlet mold 22 injects high-temperature wax liquid into the interior of the molding mold 53, and then the internal wax liquid of the molding mold 53 After the initial molding, the steering sleeve 5 drives the sliding plate 54 to continue to rotate. At this time, the second half of section A guides the sliding plate 54 downward. At this time, the molding mold 53 is separated from the wax mold 22, and the sliding plate 54 moves to section B to place the molding mold 53 in the air for heat dissipation. Then the steering sleeve 5 continues to rotate to drive the sliding plate 54 to move to section C. Section C guides the sliding plate 54 to sink into the interior of the cooling water tank 11. At this time, the molding mold 53 is immersed in the interior of the cooling water tank 11 for cooling. After cooling, the steering sleeve 5 rotates to rotate the cooled molding mold 53 back to section D. When the card slot 541 slides outside the multi-section guide rail 4, its movement stability needs to be ensured. At this time, the limiting rod 542 at one end of the sliding plate 54 will drive the limiting sleeve 56 to follow the limiting rod 542 to slide inside the guide slot 23. Due to the limitation of the limiting sleeve 56, the limiting rod 542 can remain stable. The limiting rod 542 can limit the sliding plate 54 to keep it in a vertical stable state, and the slider 561 limits the limiting sleeve 56 inside the guide slot 23.

[0044] The guide hole inside the rotating arm 52 provides a movable space for the second telescopic rod 521 when it moves, so that the second telescopic rod 521 can move freely inside the telescopic hole of the rotating arm 52, and the second telescopic rod 521 is limited by the sliding plate 54 and the rotating arm 52 to prevent it from falling off from the rotating arm 52 during the movement;

[0045] During the working process, there will be four groups of molding molds 53 in different working positions. When the first group of molding molds 53 enters section B, it will stay under the air inlet pipe 32, and the molding mold 53 at the other end will stay under the exhaust pipe 33. At this time, the fan 31 will exhaust air from the inside of the air guide pipe 3, and the air inlet pipe 32 will suck in air. The air around the molding mold 53 under the air inlet pipe 32 will be sucked in, and heat will also enter the inside of the air inlet pipe 32 along with the air flow. At the same time, one end of the exhaust pipe 33 will blow out air, and the air can dry the surface of the molding mold 53 under the exhaust pipe 33, which can make it more convenient to remove the wax model later.

[0046] When the steering sleeve 5 rotates to continue switching the work station, the molding mold 53 moves from under the exhaust duct 33, and the docking block 343 will be stuck in the docking groove 531. At this time, the molding mold 53 will be lifted up. During this process, the docking block 343 pushes the first telescopic rod 342 to retract into the inside of the flipping rod 34. At this time, the molding mold 53 is turned over and the wax mold inside can fall off from the inside of the molding mold 53. Then, the molding mold 53 returns to its original position under the action of the coil spring 552, and the reset spring 341 will also push the first telescopic rod 342 to return to its original position. At this time, the completed wax mold can be automatically taken out, and the workers can collect the wax mold.

[0047] 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. The above embodiments and descriptions are only for explaining the principles of the present invention.
