[0031] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a wax injection machine with a liquid spraying assembly, including a base 1, a bracket 2 is fixed on the top of the base 1, an upper cylinder 3 is fixed on the top of the bracket 2, the output end of the upper cylinder 3 movably passes through the top of the bracket 2, a square plate 4 is fixed at the bottom of the output end of the upper cylinder 3, an upper mold 5 is fixed at the bottom of the square plate 4, a lower mold 6 is fixed on the top of the base 1, and the lower mold 6 is located below the upper mold 5, and also includes:

[0032] The liquid spraying mechanism 7 includes a mounting plate 8 fixed on the side of the base 1, a side cylinder 9 is fixed on the side of the mounting plate 8, the output end of the side cylinder 9 movably penetrates the mounting plate 8, a shell 11 is fixed on the output end of the side cylinder 9, the shell 11 is located between the upper mold 5 and the lower mold 6, an inner cavity 12 is provided inside the shell 11, a receiving groove 15 is provided at the bottom of the shell 11, the receiving groove 15 is connected with the inner cavity 12, the receiving groove 15 is located above the mold cavity of the lower mold 6, an inner cylinder 14 is fixed on the inner wall of the inner cavity 12, the top of the inner cylinder 14 is fixed through the shell 11, an outlet 20 is provided at the top of the inner cylinder 14, a connecting pipe 13 is fixed through the side of the shell 11, the connecting pipe 13 is connected with the shell 11, a nozzle 18 is provided inside the shell 11, and an inlet 19 is provided at one end of the nozzle 18 close to the upper mold 5, and a spray nozzle 18 is provided inside the shell 11. A nozzle 21 is fixed at the bottom of the tube 18. The nozzle 21 is spherical and is located in the receiving groove 15. A circular ring 22 is fixedly sleeved on the surface of the nozzle 18. The side of the circular ring 22 is slidably connected to the inner wall of the inner cylinder 14. A spring 23 is fixedly connected between the bottom of the circular ring 22 and the inner cavity 12. A limiting ring 16 is fixed on the side of the inner cavity 12 close to the nozzle 21. The limiting ring 16 is located between the spring 23 and the nozzle 18. The connecting pipe 13 is connected to an external high-pressure pump, which provides a release agent for it. When the nozzle 18 is not in use, it is located in the groove at the top of the inner cylinder 14. At this time, the nozzle 18 not only blocks the outlet 20, but also blocks the inlet 19 of the nozzle 18 itself. When the inner cylinder 14 is filled with the release agent, the nozzle 18 moves downward, and the inlet 19 and the outlet 20 leak out after the movement.

[0033] like Figure 3 As shown, in this embodiment, the top of the inner cylinder 14 and the top of the shell 11 are in the same plane, so as to avoid collision between the top of the inner cylinder 14 and the upper mold 5 when the shell 11 is moving.

[0034] like Figure 3 As shown, in this embodiment, the ring 22, the nozzle 18 and the inner tube 14 are all concentrically arranged. After the concentric arrangement, the nozzle 18 is more stable when moving in the inner tube 14.

[0035] like Figure 3 As shown, in this embodiment, the top of the limiting ring 16 is arranged parallel to the top of the circular ring 22, so that the circular ring 22 can fit on the top of the limiting ring 16 and the force is evenly applied when fitting.

[0036] like Figure 3 As shown, in this embodiment, a circular pad 17 is fixed on the top of the limiting ring 16. The inner diameter and outer diameter of the circular pad 17 are the same as those of the limiting ring 16. When the bottom of the circular ring 22 hits the top of the limiting ring 16, the impact force generated is relatively large. The circular pad 17 is provided to buffer and absorb the impact force, thereby preventing the circular ring 22 from breaking after long-term use.

[0037] like Figure 3As shown, in this embodiment, the round pad 17 is a rubber pad, and the rubber material is relatively soft, which further absorbs the force of the limiting ring 16 when it hits.

[0038] like Figure 3 As shown, in this embodiment, the elastic force of the spring 23 is greater than the total gravity of the nozzle 18 and the nozzle 21 , so that the spring 23 can stably support the nozzle 18 and the nozzle 21 .

[0039] like Figure 1 As shown, in this embodiment, a guide rod 10 is fixed to the side of the housing 11. The guide rod 10 movably passes through the side of the mounting plate 8. The guide rod 10 is used to guide the housing 11 when it moves in the horizontal direction.

[0040] like Figure 1 As shown, in this embodiment, the guide rod 10 is arranged in parallel with the side cylinder 9, the guide rod 10 is arranged horizontally, and the side cylinder 9 is also arranged horizontally. Only when the two are arranged in parallel can the guide rod 10 have the ability to guide the shell 11 in the horizontal direction.

[0041] like Figure 2 As shown, in this embodiment, there are two shells 11, and the two shells 11 are symmetrically arranged about the middle of the base 1. The two shells 11 are respectively located between different upper molds 5 and lower molds 6, and can be sprayed with release agents at the same time, which is more convenient to use.

[0042] Working principle: before making the wax mold, it is necessary to spray the release agent in the upper mold 5 and the lower mold 6. At this time, the side cylinder 9 is started, and the shell 11 is driven to move by the side cylinder 9. When the shell 11 moves between the upper mold 5 and the lower mold 6, the upper cylinder 3 is started, and the upper mold 5 is driven to move downward by the upper cylinder 3, so that the bottom of the upper mold 5 is five millimeters away from the top of the shell 11. Then the high-pressure pump is started, and the high-pressure pump sucks the release agent and sends it to the inner cylinder 14 through the connecting pipe 13. After the release agent is sent in, the pressure in the space inside the inner cylinder 14 and at the top of the ring 22 increases. The space pressure here is greater than the pressure below the ring 22. At this time, the pressure will drive the ring 22 to move downward, and the ring 22 drives the nozzle 18 to move downward. The nozzle 18 brings The movable nozzle 21 moves downward, and the nozzle 21 is separated from the receiving groove 15 until the bottom of the ring 22 contacts the circular pad 17 on the top of the limit ring 16. At this time, the demoulding agent enters the nozzle 18 from the inlet 19 and is sprayed out from the nozzle 21 to completely spray the inner wall of the mold cavity of the lower mold 6. Then, a part of the demoulding agent is sprayed out from the outlet 20 at the bottom of the upper mold 5. After the spraying is completed, the high-pressure pump is stopped. At this time, the spring 23 drives the ring 22 to move upward, and the ring 22 drives the nozzle 18 and the nozzle 21 to move upward. The nozzle 21 is stored in the receiving groove 15, and then the side cylinder 9 is started, and the shell 11 is driven by the side cylinder 9 to leave between the upper mold 5 and the lower mold 6. Then the upper cylinder 3 is started again to fit the upper mold 5 on the lower mold 6 for wax mold manufacturing.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
