Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an air blowing cooling mechanism applied to a hot forming mold. Background Art

[0002] Automotive thermoforming parts are now widely used. Thermoforming molds play a vital role in part forming. How to make thermoforming parts more stable and better in size requires continuous efforts on thermoforming molds. At present, thermoforming molds mainly rely on cooling water to cool parts. The flow of cooling water in mold inserts mainly depends on the arrangement of water channels in inserts. However, the arrangement of water channels is limited by many factors such as part configuration, insert block, punch, core press, and ejection, resulting in the water channels not being ideally evenly arranged at the same depth from the insert surface. Therefore, after producing a certain number of parts, the water channels farther away from the insert take away less heat, and hot spots appear on the surface of the insert, that is, there will be a situation where the local temperature in a certain area is higher. This hot spot usually reaches 300°C or even higher on the mold, but other positions of the mold will be affected by cooling water and will return to below 25°C. This temperature difference will be reflected on the part, and the mold ejection temperature of the part at this point will be about 200°C higher than that of other positions, resulting in unstable dimensions of the part at this position. Summary of the invention

[0003] In view of this, the utility model aims to propose an air blowing cooling mechanism applied to a thermoforming mold, so as to solve the problem of performing targeted air blowing heat dissipation on the hot spot to cool the mold hot spot, thereby achieving the purpose of improving the dimensional stability of the part.

[0005] A blowing cooling mechanism applied to a thermoforming mold comprises a mold, wherein the mold is provided with a mold cavity, a hot spot exists in the mold cavity, and the mold is provided with a blowing device, which is arranged around the mold cavity. The blowing device comprises an air pipe, a blowing pipe and a blowing port, wherein the air pipe is fixed to the mold and is connected to the blowing pipe; the blowing port is arranged on the blowing pipe, and the blowing port corresponds to the position of the hot spot.

[0006] Compared with the prior art, the utility model has the following advantages:

[0007] The air blowing cooling mechanism applied to the thermoforming mold described in the utility model achieves the purpose of improving the dimensional stability of the part by aligning the air blowing port with the hot spot position of the mold, that is, performing fixed-point air blowing to dissipate heat at the hot spot to cool the hot spot of the mold.

[0014] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0015] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "back", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0016] The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0017] This embodiment relates to a blowing cooling mechanism applied to a thermoforming die, which can solve the problem of blowing air for heat dissipation at a fixed point for hot spots to cool the hot spots of the die, so as to achieve the purpose of improving the dimensional stability of parts.

[0018] Based on the above design concept, an exemplary structure of the blowing cooling mechanism applied to a thermoforming die in this embodiment is as Figures 1-3As shown in the figure, it mainly includes a mold 1. There is a mold cavity on the mold 1, and there is a hot spot in the mold cavity. A blowing device 2 is provided on the mold 1. The blowing device 2 is arranged around the mold cavity. The blowing device 2 includes an air pipe 201, a blowing pipe 202 and a blowing port 2021. The air pipe 201 is fixed on the mold 1, and the air pipe 201 is communicated with the blowing pipe 202. The blowing port 2021 is arranged on the blowing pipe 202, and the blowing port 2021 corresponds to the hot spot position.

[0019] When the blowing and cooling mechanism applied to the thermoforming mold described in this embodiment is in use, the blowing port 2021 is aligned with the hot spot of the mold cavity and then fixedly installed. When installing, it should be noted that the blowing pipe 202 needs to ensure that it does not interfere with the mold cavity during the stamping process. The air pipe 201 is fixed on the mold 1 after verifying that the blowing and cooling is effective, so as to ensure that there is no air leakage at the air pipe joint due to the loosening of the joint during the stamping process. That is, the blowing device 2 blows intermittently with the stamping movement of the mold 1. Specifically, when the mold 1 is opened and the robot removes the part, the blowing port 2021 starts to blow air, and the blowing port 2021 stops blowing air before the next blank enters the mold 1.

[0020] The blowing and cooling mechanism applied to the thermoforming mold adopting the above implementation scheme well realizes the situation that there are hot spots in the mold during mass production due to the uneven arrangement of the mold water channels. By blowing pressurized air from the blowing port 2021 to the hot spot position of the mold 1, since the hot spot position is not designed in the initial design stage, but is actually observed by the thermal imager, the blowing port 2021 is highly targeted. Fixed-point blowing and heat dissipation are carried out for the hot spot to cool the hot spot of the mold 1, so as to achieve the purpose of improving the dimensional stability of the part.

[0021] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
