Description

Technical Field

[0001] The invention relates to the technical field of wax piece injection molding, in particular to an injection molding mechanism for wax piece injection molding processing. Background Art

[0002] Wax injection molding is an important molding process. The wax material is placed in the barrel of the injection molding mechanism, and the heating device outside the barrel heats it to the appropriate temperature to obtain ideal fluidity. The screw rotates in the barrel, pushing the wax material forward and fully plasticizing it. After that, 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 with excellent thermal conductivity. Its cavity is precise and the surface is smooth, which can shape high-quality wax parts. The cooling system around the cavity allows the wax material to solidify quickly. After molding, the mold opens and the ejector mechanism pushes the wax part out. This process is widely used in industries such as jewelry processing and precision casting. It can efficiently produce complex shapes and high-precision wax parts, providing a high-quality foundation for subsequent processes. It occupies a unique position in the manufacturing industry and promotes the diversification and refinement of products in related fields.

[0003] During the initial melting of the wax and transferring it into the mold, since the transfer distance and temperature will affect the coagulation of the melted wax, the wax in the center of the transfer pipe may not be able to fully receive the heating outside the pipe, and thus coagulate in the center of the pipe.

After the top mold 69 and the bottom mold 77 are fitted together, the telescopic rod 46 will drive the support plate 47 to move toward the two lower molds and allow the inner cavity block 48 to enter the two molds. Only then will the melted wax be injected into the molds.

[0042] The bottom of the mainframe 41 is fixedly connected to the top of the support platform 1 .

[0043] like Figure 8-Figure 9 As shown, the molding unit 7 includes a servo motor 2 71, the output end of the servo motor 2 71 is fixedly connected to a screw rod 72, the outer surface of the screw rod 72 is threadedly connected to a moving block 73, the outer surface of the moving block 73 is fixedly connected to a support plate 3 74, the top of the support plate 3 74 is rotatably connected to a rotating shaft 2 75, the outer surface of the rotating shaft 2 75 is fixedly connected to a rotating block 76, the outer surface of the rotating block 76 is fixedly connected to a bottom mold 77, a slide groove 78 is provided on the support table 1 near the screw rod 72, and the outer surface of the support plate 3 74 is fixedly connected to a cleaning mechanism 79.

[0044] 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.

[0045] 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.

[0046] like Fig.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.

[0047] 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.

[0051] The specific workflow is as follows: 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.
