[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an in-mold cut-ring bottle cap mold provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the water inlet pipe; Figure 3 for Figure 2 The diagram shows a cross-sectional view of the cooling device. Figure 4 for Figure 3 The enlarged schematic diagram at point A is shown. A mold for an in-mold cut-ring bottle cap includes: a base 1;

[0029] The lower mold 2 is fixedly installed on the top of the base 1. The upper mold 3 is provided on the top of the lower mold 2.

[0031] The dispersion device 13 is fixedly connected to the interior of the cooling device 7. The dispersion device 13 includes a dispersion box 131, an opening 132, a conical cavity 133, and a connecting groove 134.

[0032] Heat sink 14, a plurality of heat sinks 14 are respectively fixedly installed on the surface inside the cooling device 7, and protrusions 15 are fixedly installed on the surface of the heat sink 14.

[0033] The cooling box 71 is fixedly connected to the bottom of the water inlet pipe 4, the opening cavity 72 is opened inside the cooling box 71, and the connecting groove 73 is opened at the bottom of the opening cavity 72.

[0034] The dispersion box 131 is fixedly installed inside the opening cavity 72. The opening hole 132 is opened in the middle of the top of the dispersion box 131. The conical cavity 133 is opened in the middle of the interior of the dispersion box 131. The two connecting grooves 134 are respectively opened on both sides of the bottom of the conical cavity 133.

[0035] A liquid injection pipe 8 is fixedly installed on one side of the top of the upper mold 3, and a heating device 9 is fixedly installed on the outer surface of the liquid injection pipe 8. An oil pipe 12 is fixedly installed on one side of the outer surface of the lower mold 2.

[0036] Both the upper mold 3 and the lower mold 2 are fixedly mounted with connecting plates 10, and bolts 11 are provided on the surface of the connecting plates 10.

[0037] Multiple bumps 15 are installed on the surface of the heat sink 14. The bumps 15 are made of the same material as the heat sink 14, which increases the area of ​​the heat sink 14 and enhances the guiding effect of the heat sink 14.

[0038] The dispersion box 131 is cone-shaped. The coolant inside the cone cavity 133 flows downward through the connecting groove 134, is first injected into the connecting groove 73 and then into the opening cavity 72, so that the coolant can be evenly injected into the interior of the cooling box 71.

[0039] The upper mold 3 has a cavity in the middle of its bottom for injection molding, which is existing technology. The cooling device 7 is installed at the top of the cavity to cool the bottle caps formed inside the cavity.

[0040] The working principle of the in-mold ring-cut bottle cap mold provided by this utility model is as follows:

[0041] During operation, coolant is first injected into the water inlet pipe 4. The coolant flows spirally through the spiral cooling groove 6, which slows down the flow speed of the coolant and the water inlet pipe 4 inside the upper mold 3 and increases the residence time of the coolant.

[0042] Coolant is injected into the interior of the conical cavity 133 through the opening 132 and flows into the connecting groove 134. It is injected into the interior of the connecting groove 73 and the opening 72 through the two connecting grooves 134. The cooling box 71 dissipates heat from the bottle cap in the bottom mold cavity.

[0043] Compared with related technologies, the in-mold ring-cut bottle cap mold provided by this utility model has the following beneficial effects:

[0044] This invention provides an in-mold ring-cut bottle cap mold. By setting a spiral cooling pipe on the inner wall of the water inlet pipe 4, the coolant enters the spiral cooling tank 6 from the water inlet pipe 4, spirals upward or downward in the pipe, enters the cooling box 71, and finally flows out from the drain pipe 5. This spiral pipe design can increase the flow path and residence time of the coolant in the cooling box, so that the heat exchange between the coolant and the cooling box wall is more sufficient, thereby more effectively removing the heat inside the mold cavity. At the same time, a dispersion box 131 and a heat dissipation block 14 are set in the cooling box 71 to further guide the flow direction of the coolant, so that the coolant is evenly distributed inside the cooling box 71, improving the heat dissipation effect of the device and improving the efficiency of product cooling and molding.

[0048] The upper mold 2 has positioning grooves 25 around its top, and conical positioning holes 22 on both sides of its top. The upper mold 3 has positioning pins 24 fixedly installed around its bottom, and conical positioning pins 23 fixedly installed on both sides of its bottom.

[0049] The movable block 21 has threaded holes and sliding holes on its surface. It is threadedly engaged with the outer surface of the threaded rod 18 through the threaded holes and sleeved on the outer surface of the limit rod 19 through the sliding holes.

[0050] The working principle of the in-mold ring-cut bottle cap mold provided by this utility model is as follows:

[0051] During operation, the output shaft of the servo motor 17 is first rotated by the external power supply, which drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 engages the moving block 21, which in turn moves the upper mold 3 to precisely cover the surface of the lower mold 2. The conical positioning pin 23 is first inserted into the conical positioning hole 22, and then the positioning pin 24 is inserted into the positioning groove 25.

[0052] Compared with related technologies, the in-mold ring-cut bottle cap mold provided by this utility model has the following beneficial effects:

[0053] This utility model provides an in-mold ring-cut bottle cap mold. The output shaft of a servo motor 17 is rotated by an external power source, driving a threaded rod 18 to rotate. The rotation of the threaded rod 18 engages with a threaded moving block 21, which in turn moves the upper mold 3 to precisely cover the surface of the lower mold 2. A conical positioning pin 23 first embeds into the conical positioning hole 22, and then a positioning post 24 embeds into the positioning groove 25. This device has a simple structure, high practicality, and automates mold opening and closing, eliminating the need for manual mold operation. When the conical positioning pin 23 and the conical positioning hole 22 are engaged, they can achieve automatic centering. Furthermore, their relatively small contact area results in less wear during mold opening and closing, which helps maintain high-precision positioning over a long period and improves mold closing accuracy.
