Description

Technical Field

[0001] The invention relates to the technical field of mold wax injection equipment, and in particular to a jewelry processing mold wax injection device and method. Background Art

[0002] In the jewelry processing industry, mold wax injection is a crucial link, which is directly related to the molding effect and final quality of jewelry. Traditional jewelry processing mold wax injection devices often have some problems in the wax injection process, such as difficulty in accurately controlling the wax injection amount, poor wax injection effect, and easy solidification of wax liquid, resulting in uneven discharge or blockage. These problems not only affect the molding accuracy and aesthetics of jewelry, but also increase production costs and processing difficulty.

[0003] First, it is often difficult for traditional wax injection devices to accurately control the amount of wax liquid injected during wax injection, resulting in too much or too little wax injection; too much wax injection will cause material waste and may cause bubbles or deformation inside the jewelry mold; while too little wax injection may cause incomplete jewelry molding and affect the final quality. Therefore, how to accurately control the amount of wax injection has become an urgent problem to be solved.

[0004] Secondly, traditional wax injection devices often lack effective cooling measures after wax injection, which leads to slow solidification of the wax liquid, affecting production efficiency. At the same time, since the wax liquid stays in the mold for a long time, the risk of wax liquid solidification and clogging the mold is increased. Therefore, how to quickly cool the wax liquid and improve production efficiency has become another problem that needs to be solved.

[0005] In addition, after long-term use, the wax liquid in the traditional wax injection device is prone to partially solidify inside the wax storage barrel, resulting in uneven discharge or blockage; this not only affects the continuity and stability of wax injection, but also increases the maintenance cost of the equipment. Therefore, how to avoid the discharge problem caused by partial solidification of the wax liquid is also a direction that needs to be improved in the current jewelry processing mold wax injection device. To this end, we provide a jewelry processing mold wax injection device and method. Summary of the invention

[0007] The present invention is achieved through the following technical solutions:

[0008] The invention proposes a wax injection device for jewelry processing molds, comprising a workbench and an L-shaped frame fixedly installed on the upper surface of the workbench, a wax storage barrel fixedly installed on the upper surface of the L-shaped frame, a C-shaped wax injection tube is connected to the periphery and lower end of the wax storage barrel, a wax liquid inlet is opened at the periphery of the C-shaped wax injection tube inside the wax storage barrel for the wax liquid inside the wax storage barrel to flow in, a conveyor belt is installed on the surface of the workbench for conveying jewelry processing molds, an L-shaped limit rod and a hydraulic cylinder are fixedly installed on the upper surface of the workbench respectively, an output end of the hydraulic cylinder is fixedly connected with a push plate for pushing the jewelry processing mold to below the wax outlet end of the C-shaped wax injection tube, a limit baffle is fixedly connected to the surface of the workbench for limiting excessive conveying of the jewelry processing mold, a quantitative pushing structure is connected between the workbench and the C-shaped wax injection tube; a heat dissipation and blowing assembly is connected to the C-shaped wax injection tube; a stirring component is installed in the wax storage barrel;

[0012] Furthermore, the stirring component includes a stirring rod rotatably connected to the top of the wax storage barrel through a bearing, and a stirring blade is fixedly connected to the periphery of the stirring rod inside the wax storage barrel for stirring the wax liquid inside the wax storage barrel.

[0013] Furthermore, the linkage mechanism includes a mounting block fixedly mounted on the lower end surface of the workbench and a tooth plate fixedly connected to the lower end surface of the trapezoidal plug plate, the mounting block is rotatably connected to an axial rotating rod 1 through a bearing, a gear plate is fixedly mounted on one end of the axial rotating rod 1, a bevel gear 1 is fixedly mounted on the other end of the axial rotating rod 1, an L-shaped vertical fixing plate is fixedly connected to the upper end surface of the workbench, the L-shaped vertical fixing plate is rotatably connected to an axial rotating rod 2 through a bearing, a bevel gear 2 is fixedly mounted on the lower end of the axial rotating rod 2, a belt pulley 1 is fixedly mounted on the upper end of the axial rotating rod 2, a belt pulley 2 is fixedly mounted on the upper end of the stirring rod, and a linkage belt is wrapped around the periphery of the belt pulleys 1, 2 and 3.

[0016] Furthermore, the sliding sleeve block is slidably connected to the inner wall of the strip-shaped placement groove, and the side edge is fixedly connected to the inner side wall of the plug-in through groove.

[0017] Furthermore, the gear plate is meshedly connected with the tooth plate, so that when the trapezoidal plug plate drives the tooth plate to move downward, the gear plate drives the shaft rotating rod 1 to rotate, and the bevel gear 2 is meshedly connected with the bevel gear 1, so that when the shaft rotating rod 1 rotates, the shaft rotating rod 2 is driven to rotate.

[0018] Furthermore, the height of the inner top wall of the L-shaped limiting rod is consistent with the height of the jewelry processing mold, so as to prevent the upward thrust of the trapezoidal inserting plate from pushing it upward.

[0019] Furthermore, a method for using a wax injection device for a jewelry processing mold is provided, comprising the following steps:

[0020] Start the conveyor belt on the workbench surface to transport the jewelry processing mold to be injected with wax to the working area of ​​the device; driven by the conveyor belt, the mold is transported between the L-shaped limit rod and the limit baffle. The L-shaped limit rod ensures that the mold does not move upward, while the limit baffle prevents the mold from being over-transported;

[0021] When the mold reaches the specified position, the hydraulic cylinder starts, and its output end pushes the push plate forward to push the mold below the wax outlet end of the C-shaped wax injection tube. The pushing force of the push plate acts on the slope surface of the trapezoidal plug plate at the same time, causing the trapezoidal plug plate to move downward;

[0022] The downward movement of the trapezoidal plug plate drives the gear plate to rotate through the tooth plate, and then drives the shaft rotating rod 2 to rotate through the meshing of the bevel gear 1 and the bevel gear 2; the rotation of the shaft rotating rod 2 drives the stirring rod to continue stirring the wax liquid through the belt pulley 1, the linkage belt and the belt pulley 2; the downward movement of the trapezoidal plug plate also drives the memory rod and the push plug to move downward to prepare for wax injection;

[0023] As the push plug moves downward, the trapezoidal push block pushes the baffle on the L-shaped connecting plate to rotate and expand, opening the wax outlet of the C-shaped wax injection tube, and the wax liquid is injected into the mold through the wax outlet of the C-shaped wax injection tube; at the same time, the sleeve plug moves downward with the memory rod, pushing the gas between the sleeve plug and the fixed plug into the air duct, and the air jet head is used to blow and dissipate heat during the wax injection process;

[0024] After the wax injection is completed, the hydraulic cylinder retracts the push plate, and the trapezoidal plug plate is reset under the action of spring one, while driving the gear plate and other components to reset. The baffle closes the wax outlet under the action of spring two, and the conveyor belt continues to transport the next mold to the working area to start the next wax injection cycle.

[0025] Beneficial effects of the present invention:

[0026] The present invention provides a quantitative pushing structure, so that when the jewelry processing mold is pushed to the bottom of the wax outlet end of the C-shaped wax injection tube, the memory rod can drive the pushing plug to move downward, and then the quantitative wax liquid entering the C-shaped wax injection tube from the wax liquid inlet is pushed out, so that the poor wax injection effect caused by excessive or insufficient wax injection can be avoided. In the whole process, the opening and closing mechanism is cooperated, so that the pushing plug moves downward and the trapezoidal pushing block pushes the baffle to expand, so as to achieve wax injection. Once the wax injection is completed, the baffle can be automatically closed in cooperation with the spring 2 when the jewelry processing mold is evacuated, so as to avoid the dripping of residual wax, and further ensure the wax injection effect.

[0027] The present invention arranges a heat dissipation and blowing assembly so that when the memory rod is pushed or pulled, the sleeve plug will be moved synchronously, and the gas between the sleeve plug and the fixed plug will be pushed to the air duct, and finally sprayed out by the nozzle to cool the jewelry processing mold in the wax injection, so that the jewelry processing mold can be quickly formed after the wax injection, thereby further improving the wax injection effect.

[0028] The present invention provides a stirring component and a linkage mechanism, so that the trapezoidal plug plate can achieve the rotation of the shaft rotating rod 1 while moving downward, and then cooperates with the bevel gear 1 and the bevel gear 2 to rotate the shaft rotating rod 2, and finally cooperates with the belt pulley and the linkage belt to allow the stirring rod to drive the stirring blade to rotate, so as to stir the wax liquid inside the wax storage barrel, thereby avoiding uneven discharge or blockage caused by partial solidification of the wax liquid, and once again improving the wax injection effect.

[0037] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0038] Example

[0039] like Figure 1-Figure 7 As shown, a wax injection device for jewelry processing molds proposed in one embodiment of the present invention includes a stable workbench 1, an L-shaped frame 2 is fixedly installed on the upper end of the workbench, and a wax storage barrel 3 is firmly mounted on the top of the L-shaped frame. The wax storage barrel 3 is cleverly designed to be connected with the C-shaped wax injection tube 4 to form a closed-loop wax liquid circulation system. The C-shaped wax injection tube 4 has a wax liquid inlet 5 inside the wax storage barrel 3 to ensure that the wax liquid can flow smoothly into the C-shaped wax injection tube 4; on the surface of the workbench 1, we installed an efficient conveyor belt 6 to accurately convey the jewelry processing mold to be wax-injected to the designated position. In addition, in order to more accurately control the position of the mold, we added an L-shaped limit rod 7 and a hydraulic cylinder 8 to the workbench 1. The output end of the hydraulic cylinder 8 is connected to a carefully designed push plate 9. When the mold is conveyed to the designated position, the hydraulic cylinder 8 will start, pushing the push plate 9 to accurately push the mold to the bottom of the wax outlet end of the C-shaped wax injection tube 4. In order to prevent the mold from being deflected or over-conveyed during the conveying process, a limit baffle 10 is specially provided.

[0040] Among them, we have also designed a unique quantitative pushing structure on the workbench 1. The structure includes a plug-in slot 11, in which a trapezoidal plug-in plate 12 can be inserted. The slope surface of the trapezoidal plug-in plate 12 is opposite to the push plate 9. When the push plate 9 pushes the mold, it will also apply a downward thrust to the trapezoidal plug-in plate 12. A memory rod 13 is connected to the lower end of the trapezoidal plug-in plate 12, and the memory rod 13 goes deep into the C-type wax injection tube 4 and is fixedly connected to a push plug 14. A set of precise opening and closing mechanisms are also designed between the C-type wax injection tube 4 and the push plug 14 to accurately control the opening and closing of the wax outlet. At the same time, the trapezoidal plug-in plate 12 and the stirring component are closely connected through a linkage mechanism to ensure the coordination and efficiency of the entire wax injection process; in order to further improve the wax injection effect, we have added a heat dissipation and blowing assembly to the periphery of the C-type wax injection tube 4. The assembly includes an air duct 21 and an air jet 22, which can accurately deliver cold air into the C-shaped wax injection tube 4 to quickly cool the wax liquid, thereby ensuring the accuracy and efficiency of wax injection. The inner wall of the C-shaped wax injection tube 4 is also provided with a sleeve plug 23 and a fixed plug 24. When the memory rod 13 moves downward, the sleeve plug 23 moves accordingly, pushing the gas into the air duct 21 and ejecting it through the air jet 22.

[0041] Furthermore, a combination design of a connecting square rod 17 and an L-shaped connecting plate 19 is adopted, and the L-shaped connecting plate 19 is connected to the opening groove 18 of the connecting square rod 17 through a rotating shaft. A baffle 20 is fixedly installed at the end of the L-shaped connecting plate 19, which is used to accurately control the wax outlet of the C-shaped wax injection tube 4. At the same time, we also set a spring 243 to ensure that the baffle 20 can be smoothly reset after the wax injection is completed. The lower end of the push plug 14 is connected to the connecting rod 15, and the lower end of the connecting rod 15 is connected to a trapezoidal push block 16. When the push plug 14 moves downward, the trapezoidal push block 16 will push the baffle 20 to rotate and unfold, thereby opening the wax outlet.

[0042] Furthermore, a combination design of a stirring rod 25 and a stirring blade 26 is adopted, and the stirring rod 25 is rotatably connected to the top of the wax storage barrel 3 through a bearing. The stirring blade 26 is fixed to the periphery of the stirring rod 25, and is used to fully stir the wax liquid inside the wax storage barrel 3 to ensure the uniformity and fluidity of the wax liquid.

[0043] Furthermore, a combination design of a mounting block 27, a shaft rotating rod 1 28, a gear plate 29, a bevel gear 1 31, an L-shaped vertical fixing plate 32, a shaft rotating rod 2 33, a bevel gear 2 34, a belt pulley 1 35, a belt pulley 2 36 and a linkage belt 38 is adopted. When the trapezoidal plug plate 12 moves downward, the latch plate 30 drives the gear plate 29 to rotate, and then drives the shaft rotating rod 2 33 to rotate through the meshing transmission of the bevel gear 1 31 and the bevel gear 2 34. The rotation of the shaft rotating rod 2 33 drives the stirring rod 25 to continue stirring the wax liquid through the transmission of the belt pulley 1 35, the linkage belt 38 and the belt pulley 2 36.

[0044] Furthermore, a strip placement groove 39 is provided on the side of the trapezoidal plug board 12, and a vertical fixing rod 40 and a spring 1 41 are provided in the strip placement groove 39. The sliding sleeve block 42 is slidably sleeved on the periphery of the vertical fixing rod 40, and provides a restoring force for the trapezoidal plug board 12 under the action of the spring 1 41. At the same time, the sliding sleeve block 42 is also slidably connected to the inner wall of the strip placement groove 39, and is fixedly connected to the inner side wall of the insertion through groove 11, thereby ensuring the stability and accuracy of the trapezoidal plug board 12 when moving.

[0045] Furthermore, the meshing connection design between the wheel disc 29 and the latch plate 30 is more compact and precise. When the trapezoidal insert plate 12 moves downward, the latch plate 30 will accurately drive the gear disc 29 to rotate, and then drive the stirring rod 25 and the opening and closing mechanism of the C-shaped wax injection tube 4 to work together through a series of transmission mechanisms; the inner top wall height of the L-shaped limit rod 7 is precisely calculated and is completely consistent with the height of the jewelry processing mold. This design ensures that the mold will not be moved upward by the upward thrust of the trapezoidal insert plate 12 during the pushing process, thereby further improving the accuracy and efficiency of wax injection.

[0046] Furthermore, a method for using a wax injection device for jewelry processing molds is provided, and the specific steps are as follows: start the conveyor belt 6 on the surface of the workbench 1 to convey the jewelry processing mold to be injected with wax to the working area of ​​the device. Driven by the conveyor belt 6, the mold is conveyed between the L-shaped limit rod 7 and the limit baffle 10. The L-shaped limit rod 7 ensures that the mold does not move upward, and the limit baffle 10 prevents the mold from being over-conveyed. When the mold reaches the specified position, the hydraulic cylinder 8 is started, and its output end pushes the push plate 9 to move forward, pushing the mold to the bottom of the wax outlet end of the C-shaped wax injection tube 4. The pushing force of the push plate 9 simultaneously acts on the slope surface of the trapezoidal plug plate 12, causing the trapezoidal plug plate 12 to move downward. The downward movement of the trapezoidal plug plate 12 drives the gear plate 29 to rotate through the tooth plate 30, and then drives the shaft rotating rod 2 33 to rotate through the meshing of the bevel gear 1 31 and the bevel gear 2 34. The rotation of the shaft rotating rod 23 drives the stirring rod 25 to continue stirring the wax liquid through the belt pulley 1 35, the linkage belt 38 and the belt pulley 2 36. At the same time, the downward movement of the trapezoidal plug plate 12 also drives the memory rod 13 and the push plug 14 to move downward to prepare for wax injection. As the push plug 14 moves downward, the trapezoidal push block 16 pushes the baffle 20 on the L-shaped connecting plate 19 to rotate and unfold, opening the wax outlet of the C-shaped wax injection tube 4, and the wax liquid is injected into the mold through the wax outlet of the C-shaped wax injection tube 4. At the same time, the sleeve plug 23 moves downward with the memory rod 13, pushing the gas between the sleeve plug 23 and the fixed plug 24 into the air duct 21, and the injection nozzle 22 is used to blow and dissipate the heat during the wax injection process. After the wax injection is completed, the hydraulic cylinder 8 retracts the push plate 9, and the trapezoidal plug plate 12 is reset under the action of the spring 1 41, while driving the gear plate 29 and other components to reset. The baffle 20 closes the wax outlet under the action of the spring 2 43, and the conveyor belt 6 continues to convey the next mold to the working area to start the next wax injection cycle.
