Description

Technical Field

[0001] The utility model relates to the technical field of wax injection machines, in particular to a vertical wax injection machine. Background Art

[0002] The vertical wax injection machine is a device used for wax mold forming of small and medium-sized complex, high-quality, and high-precision precision castings. It is an indispensable equipment in the production process of precision castings. It is widely used in the production of various high-end precision castings such as aircraft blades and automobile parts. When the existing vertical wax injection machine installs the mold, the lower mold is fixedly installed directly below the pressure plate. After the wax mold is made, the worker needs to reach under the pressure plate to take out the wax mold. This operation poses a great safety hazard. If the machine is accidentally started without paying attention, the pressure plate will press the worker's hand. In addition, after the existing vertical wax injection machine makes one or two sets of wax molds, the worker is required to spray isolation liquid on the upper and lower molds with a spray bottle, which increases the worker's workload.

[0026] like Figures 1 to 3As shown, this embodiment provides a vertical wax injection machine, including a workbench 1, on which two spraying structures 8 and two working modules 9 are installed, two pairs of slide grooves 11 are arranged on the workbench 1, and the two pairs of slide grooves 11 are respectively located below the two working modules 9, and sliders 2 are slidably installed on the slide grooves 11, and a moving platform 3 is installed on the slider 2, and a cavity 12 is arranged inside the workbench 1 and between the slide grooves 11, a screw rod 4 is rotatably installed in the cavity 12 through a bearing seat, a nut 5 is arranged on the screw rod 4, and the slider 2 is fixed to the nut 5, and a first motor 6 is installed in the cavity 12, and the output shaft of the first motor 6 is transmission-connected with the screw rod 4, and the screw rod 4 can be controlled to rotate by the first motor 6, and then the screw rod 4 cooperates with the nut 5 to Drive the moving platform 3 to move forward and backward. The length of the slide 11 needs to ensure that when the moving platform 3 moves to the front end of the slide 11, the moving platform 3 is located in front of the working module 9. When the moving platform 3 moves to the rear end of the slide 11, the moving platform 3 is located directly below the pressure plate of the working module 9. The moving platform 3 is provided with a mounting groove for installing the mold. The working module 9 is provided with a control module. The first motor 6 in the working platform 1, the water pump 85 in the spraying structure 8 and the second motor 87 are all connected and controlled by the control module. Two groups of control keys 7 are provided on the working platform 1. The two groups of control keys 7 respectively control the first motors 6 in the two cavities 12. The control keys 7 can be used to control the moving platform 3 to move to the front end or the rear end of the slide 11 through the first motor 6.

[0027] like Figure 3As shown, the spraying structure 8 of this embodiment includes a liquid storage tank 81, a base 82 is installed on the liquid storage tank 81, a pair of guide rods 83 are slidably installed on the base 82, a spraying pipe 84 is installed at the front end of the guide rod 83, a water pump 85 is installed on the liquid storage tank 81, the water inlet of the water pump 85 is connected to the liquid storage tank 81 through a water pipe, and the water outlet of the water pump 85 is connected to the spraying pipe 84 through a water pipe. The isolation liquid in the liquid storage tank 81 can be pumped to the spraying pipe 84 through the water pump 85, and a rack 86 is slidably installed on the base 82, and the front end of the rack 86 is fixed to the spraying pipe 84. A second motor 87 is fixedly mounted on the base 82, and a gear 88 is mounted on the output shaft of the second motor 87. The gear 88 meshes with the rack 86. The second motor 87 can control the rotation of the gear 88. Through the cooperation of the gear 88 and the rack 86, the spray pipe 84 can be driven to move forward and backward through the rack 86. The liquid storage tank 81 is provided with a liquid filling port and a transparent window. The transparent window is in a vertical strip shape, and the bottom of the transparent window is close to the bottom of the liquid storage tank 81. The transparent window allows workers to see the use of the isolation liquid in the liquid storage tank 81, which is convenient for workers. The person adds isolation liquid to the liquid storage tank 81 in time. The spray pipe 84 is provided with four atomizing nozzles 810, of which the nozzles of two atomizing nozzles 810 face upwards, and the nozzles of the other two atomizing nozzles 810 face downwards. When the spray pipe 84 moves between the pressing plate of the working module 9 and the moving platform 3, the upward atomizing nozzle 810 can spray isolation liquid to the mold at the bottom of the pressing plate, and the downward atomizing nozzle 810 can spray isolation liquid to the mold on the moving platform 3.

Before the machine works, the start time of the second motor 87 and the water pump 85 can be set on the control panel of the working module 9. For example, after the machine completes two wax models, before the pressure plate of the working module 9 is pressed down next time, the second motor 87 is started to move the spray pipe 84 to between the pressure plate and the movable table 3, and then the water pump 85 is started to spray the isolation liquid to the upper and lower molds, and then the second motor 87 is started again to control the spray pipe 84 to return to its original position, and then the working module 9 continues to work.

[0028] The working principle and use process of this utility model:

[0029] When using the vertical wax injection machine, the upper mold is still installed under the pressure plate of the working module 9, and the lower mold is installed on the moving table 3. Before the working module 9 controls the pressure plate to press down and close the mold, the control key 7 is used to control the first motor 6 to move the moving table 3 to the rear end of the slide 11. At this time, the moving table 3 is located directly under the pressure plate of the working module 9, and then the working module 9 starts to work. After the wax mold is made, the pressure plate on the working module 9 returns to its original position, and the control key 7 is used again to control the first motor 6 to move the moving table 3 to the front end of the slide 11. At this time, the moving table 3 is located directly under the pressure plate of the working module 9. In front of the working module 9, the worker then takes off the wax model on the mold. At this time, if the working module 9 is started by mistake, because the moving platform 3 is located in front of the working module 9, the worker's hand is not under the pressing plate when taking the wax model, and the pressing plate will not press the worker's hand. After the machine completes two wax models, before the pressing plate of the working module 9 is pressed down next time, the second motor 87 is started to move the spray pipe 84 between the pressing plate and the moving platform 3, and then the water pump 85 is started to spray the isolation liquid on the upper and lower molds, and then the second motor 87 is started again to control the spray pipe 84 to return to its original position, and then the working module 9 continues to work.

[0030] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
