Description

Technical Field

[0001] The present invention relates to the technical field of wax injection machines, in particular to an intelligent wax injection machine. Background Art

[0002] Investment casting, also known as lost wax casting, includes processes such as pressing wax, trimming wax, forming trees, dipping slurry, melting wax, pouring molten metal and post-processing. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then apply mud on the wax mold, which is the clay mold. After the clay mold is dried, it is baked into a ceramic mold. Once baked, the wax mold is completely melted and lost, leaving only the ceramic mold. Generally, a pouring port is left when making the clay mold, and then molten metal is poured into the pouring port. After cooling, the required parts are made. At present, wax mold manufacturing is usually completed by a wax shooting machine. The wax shooting machine is a molding equipment for investment casting, used for pressing wax patterns, and is an indispensable key equipment in the modern investment manufacturing industry.

[0023] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0025] See also Figure 1 - Figure 10 An embodiment of the present invention provides a technical solution: an intelligent wax injection machine, comprising a wax injection machine body 1, a workbench 4 arranged at the lower end of the wax injection machine body 1, and a side workbench 3 fixed to one side of the workbench 4, and also comprising a movable mold base 5, the movable mold base 5 is slidably arranged on the side workbench 3 and the upper surface of the workbench 4 to hold the wax injection mold. Preferably, a fixing part is provided on the movable mold base 5 for fixing the mold after installation.

[0026] The intelligent wax injection machine provided in this embodiment also includes a nozzle assembly, which is arranged in the wax injection machine body 1, and the nozzle assembly includes a support frame 21 fixed in the wax injection machine body 1, a wax injection outer tube 28 slidably installed on the support frame 21, and a telescopic tube 30 slidably installed inside the wax injection outer tube 28. Preferably, the support frame 21 is an inverted "L"-shaped structure, one end of the wax injection outer tube 28 passes through the support frame 21 and is installed with an external nozzle 33, the external nozzle 33 is a conical structure, and side holes 34 are evenly provided on the side of the external nozzle 33. A second hydraulic cylinder 31 for driving the telescopic tube 30 to slide axially along the wax injection outer tube 28 is fixed on the support frame 21, and an internal nozzle 42 is installed at the end of the telescopic tube 30 away from the second hydraulic cylinder 31.

[0027] In the present solution, it should be noted that, since the wax shooting outer tube 28 is slidably connected to the support frame 21, in order to prevent the wax shooting outer tube 28 from escaping from the range of the support frame 21, it is preferred that the maximum outer diameter of the outer nozzle 33 is larger than the outer diameter of the wax shooting outer tube 28, and the wax shooting outer tube 28 is away from the outer nozzle 33 as the tail, and the outer diameter of the tail is larger than the outer diameter of the wax shooting outer tube 28, so as to prevent the wax shooting outer tube 28 from escaping from the range of the support frame 21. When the wax shooting outer tube 28 moves toward the mold, the outer nozzle 33 on the wax shooting outer tube 28 will be inserted into the mold, thereby resisting the wax liquid inlet of the mold. In order to prevent the wax liquid from overflowing from the wax liquid inlet of the mold, a rubber pad can also be installed on the outer nozzle 33 to improve the airtightness between the wax liquid inlet of the mold and the outer nozzle 33.

[0028] In order to realize the driving of the telescopic tube 30, a fixing seat 37 is fixed on the outside of the wax injection outer tube 28, and a sleeve 29 is provided on the fixing seat 37. A limiting through groove 38 is opened on the outside of the sleeve 29. A connecting seat 32 is fixed at one end of the telescopic tube 30. The lower end of the connecting seat 32 passes through the wax injection outer tube 28 and extends to the inside of the sleeve 29. The lower end of the connecting seat 32 is slidably connected to the limiting through groove 38 to improve the stability of the connecting seat 32 during movement. In addition, a spring 39 is installed between one end of the sleeve 29 and the connecting seat 32. The telescopic end of the second hydraulic cylinder 31 extends to the inside of the sleeve 29 and is fixedly connected to the connecting seat 32.

[0029] In this embodiment, when the nozzle assembly inputs wax liquid into the mold, under the setting of the spring 39, the resistance of the telescopic tube 30 when moving is greater than the resistance of the wax injection outer tube 28 when moving, and then the second hydraulic cylinder 31 preferentially drives the wax injection outer tube 28 and the telescopic tube 30 to move synchronously, so that the outer nozzle 33 is inserted into the mold to limit the further movement of the wax injection outer tube 28. At this time, when the second hydraulic cylinder 31 continues to extend, the spring 39 is compressed, so that the connecting seat 32 slides inside the sleeve 29, and then pushes the telescopic tube 30 to move, so that the inner nozzle 42 can be controlled. The position of the inner nozzle 42 is controlled to control the depth of the inner nozzle 42 after being inserted into the mold, thereby improving the wax mold forming effect. When the second hydraulic cylinder 31 contracts, the spring 39 is first relaxed. At this time, the position of the inner nozzle 42 inside the mold can be adjusted according to the wax liquid input amount inside the mold to reduce the flow effect of the wax liquid inside the mold, thereby reducing the flow marks on the surface of the wax film after forming. Through the arrangement of the wax injection outer tube 28, the outer nozzle 33, the side hole 34 and the telescopic tube 30, and the inner nozzle 42, multi-channel wax injection is realized, the wax liquid output efficiency is accelerated, the wax liquid is more uniform inside the mold, and the wax mold forming effect is improved.

[0030] like Figure 8 - Figure 10 As shown, in order to facilitate the movement of the telescopic tube 30, a sliding channel 45 is provided inside the wax injection outer tube 28, so that the telescopic tube 30 can move inside the wax injection outer tube 28. In addition, a piston 40 adapted to the sliding channel 45 is provided on the fixed sleeve outside the telescopic tube 30. It should be noted that the piston 40 here is mainly used to isolate the flow of the two sections of wax liquid, and prevent the wax liquid from flowing into the sliding channel 45 between the outer nozzle 33 and the piston 40.

[0031] To facilitate the input of wax liquid, a wax delivery channel 43 connected to the side hole 34 is opened inside the wax injection outer tube 28 near the outer wall. The wax delivery channel 43 is connected to the sliding channel 45 at one end away from the outer nozzle 33 for the flow of wax liquid. A through hole 41 is opened on the outside of the telescopic tube 30 at a position inside the wax injection outer tube 28. The through hole 41 is used to input the wax liquid inside the telescopic tube 30 into the wax delivery channel 43.

[0032] In this solution, by inputting the wax liquid into the telescopic tube 30, under the setting of the through hole 41, the wax liquid flows into the sliding channel 45, and further flows into the wax delivery channel 43, which is beneficial to the wax injection of the outer nozzle 33 and the inner nozzle 42.

[0033] like Figure 6 - Figure 10As shown, in order to prevent the wax liquid from solidifying inside the nozzle assembly and causing blockage of the nozzle assembly, a heating channel 44 is opened inside the wax shooting outer tube 28 between the wax delivery channel 43 and the sliding channel 45 to keep the wax liquid inside the wax shooting outer tube 28 and the telescopic tube 30 warm. A first connecting water pipe 35 communicating with the heating channel 44 is installed at the upper end of the outer side of the wax shooting outer tube 28, and a second connecting water pipe 36 communicating with the heating channel 44 is provided at the lower end of the outer side of the wax shooting outer tube 28. It should be noted that the lengths of the first connecting water pipe 35 and the second connecting water pipe 36 can meet the movement of the wax shooting outer tube 28, so as to avoid the wax shooting outer tube 28 being excessively pulled by the first connecting water pipe 35 and the second connecting water pipe 36 when moving.

[0034] During use, hot water is input through the second connecting water pipe 36, and the hot water enters the heating channel 44. After the heating channel 44 is filled with hot water, the hot water can be output through the first connecting water pipe 35. This process can achieve heating and insulation of the wax injection outer tube 28 and the telescopic tube 30, avoid solidification of the wax liquid inside the nozzle assembly, and improve the wax liquid output efficiency.

[0035] like Figure 1 - Figure 3 As shown, in order to facilitate the movement of the movable mold base 5, a slide groove slidably connected to the movable mold base 5 is provided on the wax injection machine body 1 and the side workbench 3, and a movable frame 9 slidably connected to the slide groove is fixed on one side of the movable mold base 5. One end of the movable frame 9 passes through the wax injection machine body 1, and an electric telescopic cylinder 17 for driving the movable frame 9 to move is installed in the wax injection machine body 1.

[0036] In this solution, the movable frame 9 is driven to slide inside the slide groove by the electric telescopic cylinder 17, so that the movable mold base 5 moves synchronously, thereby controlling the position of the movable mold base 5 to avoid the operator directly operating inside the wax injection machine body 1, thereby improving the safety performance of the equipment when in use.

[0037] like Figure 3 As shown, for the convenience of moving the mold base 5, a copper tube 16 is provided inside the mold base 5. Preferably, the copper tube 16 is arranged in a zigzag shape inside the mold base 5 for rapid heating or cooling of the mold base 5. A supporting plate 6 is installed at the upper end of the movable mold base 5, and a water inlet pipe 18 connected to one end of the copper tube 16 is installed inside the movable frame 9, and a water outlet pipe 19 connected to the other end of the copper tube 16 is also provided inside the movable frame 9.

[0038] In order to facilitate the injection of water into the copper tube 16 , a pipeline component is installed at one end of the movable frame 9 through the wax injection machine body 1 for inputting hot water or cold water into the copper tube 16 .

[0039] In this solution, it should be noted that before the wax liquid is input into the mold, hot water is controlled to be input into the copper tube 16 through the pipeline assembly to preheat the mold, increase the temperature of the mold and reduce the temperature difference between the wax liquid and the mold, which helps to improve the fluidity of the wax liquid and reduce condensation on the mold surface. After the wax liquid is input into the mold, cold water is controlled to be input into the copper tube 16 through the pipeline assembly to cool the mold, which is conducive to the rapid molding of the wax liquid inside the mold and accelerates production efficiency.

[0040] like Figure 1 - Figure 3 As shown, the pipeline assembly provided in this embodiment includes a first tee pipe, which is installed at one end of the water inlet pipe 18, one of the pipe ends of the first tee pipe forms a hot water inlet pipe 10, and the other pipe end of the first tee pipe forms a cold water inlet pipe 12; and also includes a second tee pipe, which is installed at one end of the water outlet pipe 19, one of the pipe ends of the second tee pipe forms a hot water outlet pipe 11, and the other pipe end of the second tee pipe forms a cold water outlet pipe 13.

[0041] In order to control the circulation of hot and cold water, the pipeline assembly provided in this embodiment also includes a solenoid valve 14, which is a three-way valve. The solenoid valve 14 is arranged in the middle section of the first three-way pipe and the second three-way pipe. A control assembly is provided between the two solenoid valves 14 for synchronously controlling the opening and closing of the two solenoid valves 14.

[0042] In this solution, the solenoid valve 14 is controlled by the control assembly so that the hot water inlet pipe 10 is connected to the water inlet pipe 18, and the water outlet pipe 19 is connected to the hot water outlet pipe 11. At this time, the cold water inlet pipe 12 and the cold water outlet pipe 13 are in a closed state for the input and output of hot water inside the copper tube 16. The solenoid valve 14 is controlled by the control assembly so that the hot water inlet pipe 10 and the hot water outlet pipe 11 are in a closed state. At this time, the cold water inlet pipe 12 and the water inlet pipe 18, and the cold water outlet pipe 13 and the outlet pipe 19 are connected for the input and output of cold water inside the copper tube 16.

[0043] like Figure 2 、 Figure 4 and Figure 5 As shown, in order to avoid the solidification of the wax liquid, a wax storage cylinder 8 is installed inside the wax injection machine body 1. Preferably, a stirring component is provided inside the wax storage cylinder 8 to stir the wax liquid and accelerate the melting of the solid wax. A first heat-insulating shell 23 is provided on the outside of the wax storage cylinder 8 to reduce heat energy loss. A first heating water pipe 24 is provided between the first heat-insulating shell 23 and the wax storage cylinder 8 to heat the inside of the wax storage cylinder 8.

[0044] In addition, in order to facilitate the use of wax liquid, a connecting plate 22 is fixed in the wax injection machine body 1, and an insulation cylinder 25 is installed on the connecting plate 22 for storing wax liquid. The input end of the insulation cylinder 25 is connected to the output end of the wax storage cylinder 8 through a pipeline, and the output end of the insulation cylinder 25 is connected to the input end of the telescopic tube 30 through a pipeline. Preferably, the pipeline connection length between the insulation cylinder 25 and the telescopic tube 30 can meet the moving range of the telescopic tube 30.

[0045] In order to improve the insulation effect of the insulation cylinder 25, a second insulation shell 26 is provided on the outside of the insulation cylinder 25, and a second heating water pipe 27 is provided between the second insulation shell 26 and the insulation cylinder 25, so as to achieve the insulation of the insulation cylinder 25. In addition, in order to facilitate the output of wax liquid, a wax liquid output pump is installed inside the insulation cylinder 25 to accelerate the wax liquid output effect. In order to facilitate the temperature monitoring of the insulation cylinder 25 and the wax storage cylinder 8, temperature sensors can be installed on the inside of the insulation cylinder 25 and the wax storage cylinder 8.

[0046] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, in order to facilitate the output of hot water, a hot water tank 7 is installed on one side of the workbench 4. Preferably, a circulation pump is installed inside the hot water tank 7. The hot water output end of the circulation pump is respectively connected to the hot water inlet pipe 10, the water inlet end of the first heating water pipe 24, the water inlet end of the second heating water pipe 27 and the second connecting water pipe 36, and the hot water return end of the hot water tank 7 is respectively connected to the hot water outlet pipe 11, the water outlet end of the first heating water pipe 24, the water outlet end of the second heating water pipe 27 and the first connecting water pipe 35.

[0047] like Figure 8 and Figure 9 As shown, to facilitate the movement of the telescopic tube 30 , the length of the telescopic tube 30 is twice the length of the wax injection outer tube 28 so that the telescopic tube 30 can better extend into the mold, and the outer diameter of the telescopic tube 30 is 1 / 3 of the outer diameter of the wax injection outer tube 28 .

[0048] like Figure 1 and Figure 2 As shown, in order to limit the movement of the mold on the movable mold base 5, a first hydraulic cylinder 15 is fixed in the wax injection machine body 1, and a pressure plate 2 is installed at the telescopic end of the first hydraulic cylinder 15. A guide telescopic rod 20 is also installed in the wax injection machine body 1, and the telescopic ends of the guide telescopic rod 20 are fixedly connected to the four corners of the pressure plate 2 respectively.

[0049] When in use (working), first input the hot water inside the hot water tank 7 into the hot water inlet pipe 10, the water inlet end of the first heating water pipe 24, the water inlet end of the second heating water pipe 27 and the inside of the second connecting water pipe 36, and heat the wax storage cylinder 8 through the first heating water pipe 24, and heat the insulation cylinder 25 through the second heating water pipe 27. Hot water is input through the second connecting water pipe 36, and the hot water enters the heating channel 44. After the heating channel 44 is filled with hot water, the hot water can be output from the first connecting water pipe 35. This process can realize the heating and insulation of the wax injection outer tube 28 and the telescopic tube 30, and prevent the wax liquid from accumulating in the nozzle. The component solidifies inside to improve the wax liquid output efficiency, and hot water is input into the copper tube 16 through the hot water inlet pipe 10 and the water inlet pipe 18, which is beneficial to the heating of the movable mold base 5. The mold is installed on the movable mold base 5 to realize the preheating of the movable mold base 5. At this time, the electric telescopic cylinder 17 is started to drive the movable frame 9 to slide inside the slide groove, so that the movable mold base 5 moves synchronously, so that the position of the movable mold base 5 can be controlled to avoid the operator directly operating on the inside of the wax injection machine body 1, thereby improving the safety performance of the equipment during use, and the first hydraulic cylinder 15 is used to make the pressure plate 2 and the upper end of the mold abut against each other to improve the sealing and fixing effect of the mold.

[0050] At this time, the second hydraulic cylinder 31 is started, and the wax injection outer tube 28 and the telescopic tube 30 are driven to move synchronously by the second hydraulic cylinder 31, so that the outer nozzle 33 is inserted into the mold to limit the further movement of the wax injection outer tube 28. When the second hydraulic cylinder 31 continues to extend, the spring 39 is compressed, so that the connecting seat 32 slides inside the sleeve 29, and then pushes the telescopic tube 30 to move, so that the position of the inner nozzle 42 can be controlled to control the depth after the inner nozzle 42 is inserted into the mold, thereby improving the wax mold molding effect. When the second hydraulic cylinder 31 contracts, the spring 39 is relaxed first. At this time, the position of the inner nozzle 42 inside the mold can be adjusted according to the wax liquid input amount inside the mold to reduce the flow effect of the wax liquid inside the mold, thereby reducing the flow marks on the surface of the wax film after molding. Through the arrangement of the wax injection outer tube 28, the outer nozzle 33, the side hole 34 and the telescopic tube 30, and the inner nozzle 42, multi-channel wax injection is realized, the wax liquid output efficiency is accelerated, the wax liquid is more uniform inside the mold, and the wax mold molding effect is improved.

[0051] After the wax liquid injection is completed, the solenoid valve 14 is controlled by the control assembly so that the hot water inlet pipe 10 and the hot water outlet pipe 11 are in a closed state. At this time, the cold water inlet pipe 12 is connected to the inlet pipe 18, and the cold water outlet pipe 13 is connected to the outlet pipe 19. The external cold water is input into the cold water inlet pipe 12, so that the copper tube 16 is filled with cold water, and the movable mold base 5 is further cooled, thereby realizing the cooling of the mold, which is beneficial to the rapid molding of the wax mold. After the wax mold is formed, the movable mold base 5 is moved to the side workbench 3 to avoid the user operating directly under the pressure plate 2, thereby improving the safety performance of the equipment.
