[0002] With the development of modern industry, plastic products have been widely used in various manufacturing industries. In order to improve the assembly efficiency and stability of products, copper nuts, as a connecting and fixing element, play an important role in plastic products. Especially in plastic products with a multi-cavity structure, the installation of copper nuts is more critical. The existing installation of multi-cavity molten copper nuts usually adopts a hot-melt process, which requires the copper nuts to be placed individually in the holes to be melted in sequence through a soldering iron head, and the temperature of the copper nuts is increased by a heating head, so that the plastic hole wall reaches the molten state. After applying a certain external force, the copper nuts can be completely integrated into the holes and form an integral body with the product. This results in manual placement being not only time-consuming and laborious, with low efficiency, but also unable to ensure the consistency of positioning accuracy and insertion depth, affecting the production quality. For this reason, the utility model proposes a limiting tooling for multi-cavity molten copper nuts. Content of the Utility Model

A heat insulation block 10 is fixedly arranged on the upper surface of the lifting plate 9, a connecting plate 11 is fixedly arranged at the upper end of the heat insulation block 10, and the connecting plate 11 is fixedly connected with the output end of the adjustable stroke cylinder 6; a heating component 12 for melting the copper nut is fixedly arranged on the bottom surface of the lifting plate 9, and the heating component 12 is located directly above the limiting component 3.
[0031] As Figure 1 and Figure 2 As shown, the limiting component 3 includes four reserved hole columns 32, a copper nut 33 is arranged inside the reserved hole column 32, a collar 34 is sleeved on the upper end of the copper nut 33. The collar 34 is made of ceramic fiber, which can insulate heat and keep warm, so that the heat of the heating head 123 is concentrated on the copper nut 33. The collar 34 is sleeved with the reserved hole column 32, a copper column 35 is sleeved inside the collar 34, and the copper column 35 is in close contact with the upper end of the reserved hole column 32.
[0032] As Figure 1 and Figure 3 As shown, the heating component 12 includes two heating blocks 121. A heating core 122 is arranged inside the heating block 121, a heating head 123 is arranged inside the heating core 122, and a set screw is arranged on the lower side of the heating head 123 to cooperate with the heating core 122 for fixation and prevent slipping. A temperature probe 124 is fixedly installed inside the heating block 121, which can measure the real-time heating temperature data to achieve effective temperature control.
[0033] Furthermore, a heat insulation plate 13 is fixedly arranged at the upper end of the heating block 121. The heat insulation plate 13 is made of ceramic fiber material and has good heat insulation effect. A heat insulation cotton 14 is arranged at the connection between the heat insulation plate 13 and the heating block 121, which can make up for the rigid connection between the heating block 121 and the heat insulation plate 13.
[0034] Secondly, an electric control box 15 is fixedly arranged on one side of the bottom plate 1. The interior of the electric control box 15 is equipped with PLC control, switching power supply, solenoid valve, temperature controller, pressure regulating valve, etc. An air pipe joint 16 penetrates through the upper surface of the electric control box 15, and there are two air pipe joints 16, which are respectively the air inlet and air outlet connecting the adjustable stroke cylinder 6.
[0035] Furthermore, a start button 17 and a reset button 18 are arranged on the upper surface of the bottom plate 1, which are convenient for controlling the start and stop of melting.
[0036] In addition, a nut 19 is threadedly sleeved on the upper end of the column 4. The nut 19 is located on the upper surface of the upper mounting plate 5 to ensure the stable installation of the column 4 and the upper mounting plate 5.
[0037] Finally, a guide sleeve 20 is arranged at the socket of the inner guide post 7 and the lifting plate 9. The guide sleeve 20 is slidably matched with the inner guide post 7, which can make the lifting plate 9 move up and down.
[0038] The working principle of this embodiment is as follows: First, connect the power supply to heat the heating block 121. The heating block 121 heats the heating head 123 through the heat core 122, and the temperature of the heating head 123 reaches 340°C through the temperature probe 124. Subsequently, the copper nuts 33 to be melted are respectively placed in the reserved holes on the four reserved hole columns 32, and then the collar 34 is sleeved on the outer wall of the copper nut 33, and the copper nut 33 is sleeved on the upper end of the reserved hole column 32. Then, the copper column 35 is placed inside the collar 34, and the lower end of the copper column 35 is closely attached to the upper end of the copper nut 33.
[0039] Furthermore, after the copper nut 33 is stably placed, press the start button 17 to start the adjustable stroke cylinder 6 to push the connecting plate 11 to move vertically downward. The connecting plate 11 drives the whole heating assembly 12 to move downward. When the lower end of the heating head 123 touches the upper end of the copper column 35, after the PLC controller receives the position signal, the adjustable stroke cylinder 6 stops moving downward, and the heating head 123 transfers heat to the copper column 35 for 20 seconds. After the timing is up, the adjustable stroke cylinder 6 continues to drive the heating head 123 to press downward. When the upper end of the copper column 35 is horizontal with the end face of the collar 34, it cannot continue to move downward, achieving the limit effect.
[0040] Finally, press the reset button 18 to start the adjustable stroke cylinder 6 to retract to the initial state, and then the product can be taken out. It can ensure accurate positioning during the melting process of four copper nuts 33 at the same time, avoid the problem of tilting of the copper nuts 33 caused by the indenter not being aligned with the center, thereby significantly improving the assembly accuracy and consistency of the product and enhancing the overall quality of the product.
[0041] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
