Description

Technical Field

[0001] The present invention relates to the technical field of wax part injection molding, and specifically relates to an injection molding mechanism for wax part injection molding processing. Background Technique

[0002] Wax part injection molding is an important molding process. The wax material is placed into the barrel of the injection molding mechanism, and the heating device outside the barrel heats it to a suitable temperature to obtain ideal fluidity. The screw rotates in the barrel, which not only pushes the wax material forward but also fully plasticizes it. Then, with the help of the drive system, the screw injects the plasticized wax material into the cavity of the closed mold through the nozzle. The mold is mostly made of aluminum alloy, which has excellent thermal conductivity. Its cavity is precise and the surface is smooth, enabling the production of high-quality wax parts. The cooling system around the cavity allows the wax material to solidify quickly. After molding, the mold is opened, and the ejection mechanism pushes out the wax part. This process is widely used in industries such as jewelry processing and precision casting, and can efficiently manufacture wax parts with complex shapes and high precision, providing a good foundation for subsequent processes, occupying a unique position in the manufacturing industry, and promoting the diversification and refinement development of products in related fields.

[0003] During the process of initially melting the wax material and transporting it into the mold, since the transmission distance and temperature can affect the condensation of the melted wax material, the wax material in the center of the transmission pipeline may not receive sufficient heating from outside the pipeline, resulting in condensation at the center of the pipeline.

The injection molding unit 6 will melt the original wax material and push it into the mold. The wax material will condense into a finished product in the molding unit 7. Then, the molding unit 7 will move the finished product to a position convenient for the staff to take and remove the wax waste in the mold, which is convenient for subsequent use.

[0036] As Figures 3 - 4 shown in the figure, the injection molding unit 6 includes a top layer 61. Slide columns 62 are evenly arranged at the bottom of the top layer 61.

An oil inlet pipe 67 is fixedly connected to the top of the hydraulic device 66. The top of the oil inlet pipe 67 is fixedly connected to the outer surface of the melting mechanism 65. A slide plate 68 is slidably connected to the outer surface of the slide column 62. A top layer mold 69 is fixedly connected to the bottom of the slide plate 68. An inlet pipe 611 is fixedly connected to the outer surface of the hydraulic device 66;

[0037] The melting device 63 will suck in the wax raw material through the inlet pipe 611 and conduct preliminary melting. Then, the melted wax material will flow into the melting mechanism 65.

[0038] As Figure 5 shown in the figure, the melting mechanism 65 includes a hose 651. One end of the hose 651 away from the melting device 63 is fixedly connected to a hot melt outer pipe 652. A inner pipe 653 is fixedly connected to the top of the hot melt outer pipe 652. A moving partition 654 is slidably connected to the outer surface of the inner pipe 653.

The bottom of the spring damper 655 is fixedly connected to the top of the top layer 61. A middle section layer 657 is arranged on the outer surface of the hot melt inner pipe 656. A gear 658 is fixedly connected to the outer surface of the middle section layer 657. A support rod 659 is fixedly connected to the inner wall of the hot melt inner pipe 656. One end of the support rod 659 is fixedly connected to a spiral stirring plate 6510.

[0039] After the melting device 63 melts the wax material, it will enter the inner tube 653 inside the hot-melt outer tube 652 through the hose 651 and be continuously heated to prevent the wax material from condensing. Then, the hydraulic device 66 will suck hydraulic oil through the second inlet pipe 611 and push it into the top of the hot-melt outer tube 652 from the oil inlet pipe 67, so as to push the moving part to move downward. As the moving partition 654 and the hot-melt inner tube 656 move downward, the spring damper 655 will be compressed. When the middle layer 657 moves to be horizontally flush with the driving mechanism 64, the driving mechanism 64 will drive the first gear 658 to rotate, and then drive the entire hot-melt inner tube 656 and the spiral stirrer to rotate, stirring the wax material at the outlet of the hot-melt inner tube 656 to prevent the wax material from condensing due to the low temperature and static state at the outlet.

[0040] The outer surface of the top layer 61 is fixedly connected to the top of the support column 5, the bottom of the hose 651 is fixedly connected to the top of the melting device 63, and the bottom of the hot-melt inner tube 656 is rotatably connected to the top of the sliding plate 68.

[0041] As Figure 6 shown, the driving mechanism 64 includes a first telescopic rod 641. The output end of the first telescopic rod 641 is fixedly connected with a push plate 642.

The output end of the first servo motor 644 is fixedly connected with a first rotating shaft 645. The bottom of the first rotating shaft 645 is fixedly connected with a second gear 646.

[0042] When the middle layer 657 moves to be horizontally flush with the driving mechanism 64, the first telescopic rod 641 will drive the push plate 642 to move towards the hot-melt inner tube 656, so that the first gear 658 meshes with the second gear 646. Then, the first servo motor 644 will drive the first rotating shaft 645 and the second gear 646 to rotate, and then drive the hot-melt inner tube 656 and the spiral stirrer to rotate.

[0043] The outer surface of the first telescopic rod 641 is fixedly connected to the inner wall of the top plate, and the second gear 646 meshes with the first gear 658.

[0044] The specific working process is as follows:

[0045] During operation, the melting device 63 melts the wax material and then enters the inner tube 653 inside the hot-melt outer tube 652 through the hose 651 and is continuously heated to prevent the wax material from condensing. Then, the hydraulic device 66 sucks hydraulic oil through the second inlet pipe 611 and pushes it into the top of the hot-melt outer tube 652 from the oil inlet pipe 67, thereby pushing the moving part to move downward. As the moving partition 654 and the hot-melt inner tube 656 move downward, the spring damper 655 will be compressed. When the middle layer 657 moves to be horizontally flush with the driving mechanism 64, the first telescopic rod 641 will drive the push plate 642 to move towards the hot-melt inner tube 656, causing the first gear 658 to mesh with the second gear 646. Then, the first servo motor 644 will drive the first rotating shaft 645 and the second gear 646 to rotate, thereby driving the hot-melt inner tube 656 and the spiral stirrer to rotate and stirring the wax material at the outlet of the hot-melt inner tube 656.

[0046] Embodiment 2, use Figures 1 - 10 The following describes an injection mechanism for wax part injection molding according to an embodiment of the present invention.

After the top mold 69 and the bottom mold 77 are fitted, the second telescopic rod 46 will drive the second support plate 47 to move downward towards the two molds and make the inner cavity block 48 enter the two molds. Then, the melted wax material will be injected into the molds.

[0049] The bottom of the main unit 41 is fixedly connected to the top of the support table 1.

[0050] As Figures 8 - 9 As shown, the forming unit 7 includes a second servo motor 71. A lead screw 72 is fixedly connected to the output end of the second servo motor 71. A moving block 73 is threadedly connected to the outer surface of the lead screw 72. A third support plate 74 is fixedly connected to the outer surface of the moving block 73. A second rotating shaft 75 is rotatably connected to the top of the third support plate 74. A rotating block 76 is fixedly connected to the outer surface of the second rotating shaft 75. A bottom mold 77 is fixedly connected to the outer surface of the rotating block 76. A chute 78 is arranged on the support table 1 near the lead screw 72. A cleaning mechanism 79 is fixedly connected to the outer surface of the third support plate 74.

[0051] Servo motor 2 71 can drive screw 72 to rotate, thereby controlling the overall moving block 73 and the finished product after injection molding to move closer to the operator, making it convenient for manual picking up and avoiding being pinched by the equipment when people reach out to pick up the finished product. The finished product can also be automatically unloaded through the cleaning mechanism 79.

[0052] The outer surface of the servo motor 2 71 is fixedly connected to the outer surface of the support platform 1 , and the bottom mold 77 and the top mold 69 are fitted to each other.

[0053] like Figure 10 As shown, the cleaning mechanism 79 includes a slider 791, the outer surface of the slider 791 is fixedly connected to a power supply 792, the outer surface of the power supply 792 is fixedly connected to a wire 793, the end of the wire 793 away from the power supply 792 is fixedly connected to an electromagnetic block 7911, the top of the slider 791 is fixedly connected to a servo motor 3 794, the output end of the servo motor 3 794 is fixedly connected to a rotating shaft 3 795, the outer surface of the rotating shaft 3 795 is fixedly connected to a disc 2 7913, the end of the rotating shaft 3 795 away from the servo motor 3 794 is fixedly connected to one end of the rotating shaft 2 75, and the outer surface of the support plate 3 74 is fixedly connected to the outer surface of the support plate 3 74. The surface is fixedly connected to a support plate four 796, the inner wall of the support plate four 796 is fixedly connected to a telescopic spring 797, the end of the telescopic spring 797 close to the electromagnetic block 7911 is fixedly connected to a magnetic block 798, the outer surface of the magnetic block 798 is slidably connected to the inner wall of the support plate four 796, the inner wall of the magnetic block 798 is rotatably connected to a rotating rod 799, one end of the rotating rod 799 close to the power supply 792 is fixedly connected to a disk one 7912, the outer surface of the disk one 7912 is sleeved with a track 7914, and the end of the rotating rod 799 away from the disk one 7912 is fixedly connected to a brush rod 7910.

[0054] During the normal injection molding process, the electromagnetic block 7911 is in a non-working state, and the pulling force of the telescopic spring 797 will make the magnetic block 798 close to one side of the support plate 3 74. At this time, the track 7914 is in a relaxed state. However, when it is necessary to clean the inner cavity of the bottom mold 77, the power supply 792 will generate magnetic force on the electromagnetic block 7911 through the wire 793 and absorb the magnetic block 798, so that the track 7914 is straightened and in a taut state.

[0055] During the wax molding process, wax will remain on the inner wall of the mold, which will affect the subsequent injection molding of wax parts. After the worker takes out the molded wax parts, servo motor 2 71 will control the moving block 73 to move to the placement slot 8, and then servo motor 3 794 will drive shaft 3 795 to rotate, and then drive shaft 2 75 to rotate, so that the bottom mold 77 rotates half a circle. In this process, the rotation of shaft 3 795 will drive disc 2 7913 to rotate and rotate the rotating rod 799 through the transmission of track 7914 and disc 3, thereby driving the brush rod 7910 to brush the inner wall of the bottom mold 77, brushing the wax and impurities attached to the inner cavity into the placement slot 8, thereby achieving a cleaning effect.

[0057] The bottom of the slider 791 is slidably connected to the outer surface of the slide groove 78 , and the outer surface of the disc 2 7913 is sleeved with the outer surface of the crawler 7914 .

[0058] The specific workflow is as follows:

[0059] During operation, as the hydraulic device 66 operates, the sliding plate 68 will be driven to move downward. After the top mold 69 and the bottom mold 77 are fitted together, the telescopic rod 46 will drive the supporting plate 47 to move toward the two lower molds, and make the inner cavity block 48 enter the two molds. Only then will the melted wax be injected into the mold. After molding, the servo motor 71 can drive the screw rod 72 to rotate, thereby controlling the overall moving block 73 and the finished product after injection molding to move close to the position of the operator, which is convenient for manual picking and avoids being pinched by the instrument when the person reaches out to pick up the finished product. At the same time, after the worker takes out the molded wax part, the servo motor 71 will control the moving block 73 moves to the placement slot 8, then the servo motor three 794 will drive the shaft three 795 to rotate, and then drive the shaft two 75 to rotate, so that the bottom mold 77 rotates half a circle. In this process, the rotation of the shaft three 795 will drive the disc two 7913 to rotate and the rotation rod 799 to rotate through the transmission of the crawler 7914 and the disc three, and then drive the brush rod 7910 to brush the inner wall of the bottom mold 77, and brush the wax and impurities attached to the inner cavity into the placement slot 8. The process of the bottom mold 77 rotating half a circle can also realize the automatic unloading of the finished product, so that the finished product automatically falls into the placement slot 8.
