[0043] Specifically, when using the device, first push the second bottom plate 7 downward to ensure that the first template 4 and the second template 10 are tightly fitted, and then inject molten plastic raw materials into the interior of multiple groups of second mold core blanks 11 through the hot nozzle 16. When the plastic raw materials cool and solidify, lift the second bottom plate 7 upward. At this time, the first mold core blank 14 and the second mold core blank 11 will naturally separate, and then the ejector frame 25 will drive the ejector pin 6 to move upward to eject the processed flip-top accessories upward, thereby facilitating the collection work of the staff, and multiple groups of first mold core blanks 11 and second mold core blanks 14 are respectively arranged on the first template 4 and the second template 10. Each group of first mold core blanks 11 and second mold core blanks 14 can produce two flip-top accessories. This design significantly improves the output quantity of the device per unit time, improves the practicality of the device, and can meet the needs of users.

[0044] Reference Figure 3 、 Figure 4 and Figure 5 , the molding mechanism 2 includes a slide rail 201, multiple slide rails 201 are fixedly connected to the corresponding groove 23, one side of the interior of the multiple slide rails 201 is slidably connected to the second inclined top 203, the other side of the interior of the multiple slide rails 201 is slidably connected to the first inclined top 202, and the interior of the multiple first inclined tops 202 is provided with a slide insert 204, the bottom of the second back plate 8 is fixedly connected to multiple connecting columns 205, the bottom ends of the multiple connecting columns 205 pass through the mounting plate 9 and are fixedly connected to the locking wedge 206, the bottom of the mounting plate 9 is fixedly connected to multiple inclined guide columns 207, the top of the first template 4 is provided with multiple holes 208, and the multiple inclined guide columns 207 are respectively plugged into the corresponding holes 208, the top left side of the second template 10 is fixedly connected to a spring 209, the top of the spring 209 is fixedly connected to the bottom of the mounting plate 9, the left and right sides of the top of the multiple slide rails 201 are provided with positioning pins 22, and the top of the second bottom plate 7 is fixedly connected to an insulating plate 24;

[0045] Specifically, in the process of using the device, when the demoulding operation is performed, the second bottom plate 7 moves upward and the second back plate 8 moves upward together. As the second back plate 8 rises, the mounting plate 9 also moves upward. In this process, the spring 209 under the mounting plate 9 will gradually stretch. At this time, the second template 10 will not move upward because it is not pulled by the spring 209. As the mounting plate 9 continues to rise, the inclined guide post 207 will also be driven to move upward. Since the inclined guide post 207 is set at an angle, when it moves upward, it will push the first inclined top 202 and the second inclined top 203 along the slide The rail 201 slides in the opposite direction, thereby driving the slider insert 204 to move, and the slider insert 204 can be separated from the flip-top part of the flip-top accessory, thereby making the demoulding process easier. When the mounting plate 9 continues to move upward, the spring 209 will stretch to its maximum length. At this time, it will drive the second template 10 to move upward together, so that the processed flip-top accessories can be effectively collected. This design not only can realize the one-piece injection molding of the flip-top accessories, but also can ensure the smoothness and efficiency of the entire demoulding process, eliminating the later splicing steps and reducing the workload of the staff.

[0046] Reference Figure 1 and Figure 6 , guide sleeve holes 12 are opened at the four corners of the bottom of the second template 10, guide columns 13 are fixedly connected to the four corners of the top of the first template 4, connectors 17 are fixedly connected to the left and right sides of the front wall of the first back plate 3 and the second template 10, and the front sides of the multiple connectors 17 are connected to the pipe openings 18;

[0047] Specifically, through the interaction between the guide sleeve hole 12 and the guide column 13, the second template 10 of the device can be accurately aligned with the first template 4, which is convenient for the staff to operate. The coolant can be connected through the pipe mouth 18 on the connector 17, so that the injection liquid can be cooled quickly.

[0048] Reference Figure 6 and Figure 7 The left and right sides of the front walls of the first bottom plate 1 and the second bottom plate 7 are fixedly connected with mold legs 19, the middle part of the left side of the first template 4 is fixedly connected with a micro switch 20, the middle part of the left side of the first back plate 3 is fixedly connected with a connecting belt 21, and the top end of the connecting belt 21 is fixedly connected to the left side of the mounting plate 9;

[0049] Specifically, the mold support feet 19 can provide protection for the device, the micro switch 20 provides an alarm when the relative positions of the first template 4 and the second template 10 are offset, and the connecting belt 21 can prevent the positions of the first template 4 and the second template 10 from being easily offset during injection molding.

[0050] Working principle: When using this device, first push the second bottom plate 7 so that the first template 4 and the second template 10 fit together. At this time, the molten plastic raw material is injected into the multiple sets of second mold core blanks 11 through the hot nozzle 16. After cooling is completed, the second bottom plate 7 is lifted upward. At this time, the first mold core blank 14 and the second mold core blank 11 are separated. Then the ejector frame 25 pushes the ejector pin 6 upward to eject the processed flip-top parts upward, making it easier for the staff to collect them. In addition, multiple sets of first mold core blanks 11 and second mold core blanks 14 are set on the first template 4 and the second template 10. Each set of first mold core blanks 11 and second mold core blanks 14 can produce two flip-top parts, which greatly increases the number of flip-top parts produced per unit time by the device.

[0051] When the second bottom plate 7 is moved upward for demoulding, the second back plate 8 will be driven to move upward, and the second back plate 8 will drive the mounting plate 9 to move upward. At this time, the spring 209 on the lower side of the mounting plate 9 will be extended, and will not drive the second template 10 to move upward. At this time, the mounting plate 9 will drive the inclined guide column 207 to move upward. Since the inclined guide column 207 is inclined, when the inclined guide column 207 moves upward, it will push the first inclined top 202 and the second inclined top 203 to slide away from each other in the slide rail 201, and drive the row insert 204 to move, so that it can be separated from the flip part of the flip cover accessory, making it easy to demould. When the mounting plate 9 continues to move, the spring 209 will be extended to its maximum length and drive the second template 10 to move upward, so that the processed flip cover accessories can be collected. This design can perform integrated injection molding of the flip cover accessories, eliminating the need for subsequent splicing steps.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
