[0005] Furthermore, there are two switching components, which are arranged symmetrically on the left and right.

[0006] Compared with the existing technology, the utility model has a positive and obvious effect. The utility model has a switching design for the hot air inlet position, so that the hot air in the hot air pipe can be switched back and forth between hot air and no hot air. When the operator takes or places the product, the hot air is switched to the non-personnel side to avoid scalding the operator. Therefore, the heater does not need to be stopped and started at will, which meets the physical requirements of the heater, avoids heater damage, increases the service life of the heater, saves costs, meets the requirements of production rhythm, and has strong application value in production.

[0010] The following is a further description of the present invention in conjunction with an embodiment. However, the present invention is not limited to the embodiment. All similar structures and similar variations of the present invention should be included in the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and does not limit the technical solution of the present invention.

[0011] like Figure 1-Figure 3 As shown, a hot air outlet switching mechanism of a hot pressing hemming mold for an automobile interior decoration of the present invention includes a switching component, which includes a base, a guide rail 27 is provided on the base, a slider is provided on the guide rail 27, a heater 24 is provided on the slider, a heater driving device 23 is provided on the base, and the power output end of the heater driving device 23 is connected to the slider, a lifting seat 22 is provided above the base, a lifting driving device 25 is provided on the base, and the power output end of the lifting driving device 25 is connected to the lifting seat 22, and a first interface 13 and a second interface 12 are provided at an upper and lower interval on the bottom of the lifting seat 22 to cooperate with the air outlet of the heater 24, the first interface 13 is connected to the first air duct 21 through a pipe, the first air duct 21 is connected to the first air outlet duct (not shown in the figure) through a hose, the outlet of the first air outlet duct is located in the direction of the product placement position, the second interface 12 is connected to the second air duct (not shown in the figure) through a pipe, the second air duct is connected to the second air outlet duct (not shown in the figure) through a hose, and the outlet of the second air outlet duct is located in the safety side direction.

[0012] Furthermore, there are two switching components, which are arranged symmetrically on the left and right.

[0013] Specifically, the guide rail 27, heater 24, heater driving device 23, lifting seat 22, lifting driving device 25, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described in detail here.

[0014] The working principle of this embodiment is as follows:

[0015] The mold is composed of three major parts: the lower mold, the upper hot mold, and the upper cold mold. The hot air outlet switching mechanism is located in the lower mold, and the actions of each drive device are controlled by PLC to complete the switching of the hot air direction.

[0016] During normal heating, the air outlet of heater 24 docks with first interface 13. The blower directs compressed air into heater 24 through interface 26 for heating. The air is then directed to the product through first interface 13, first air duct 21, and first air outlet duct for heating. When the operator places or retrieves a component, heater driver 23 drives heater 24 outward along guide rail 27, causing the heater's air outlet to disengage from first interface 13. The lift driver then drives lift base 22 upward, and heater driver 23 drives heater 24 inward along guide rail 27. The air outlet of heater 24 docks with second interface 12. Heater 24 directs hot air to the safe side (non-personnel side) through second interface 12, second air duct, and second air outlet duct. After the operator places or retrieves the component, heater driver 23 drives heater 24 outward along guide rail 27, and lift driver 25 drives lift base 22 downward, causing the air outlet of heater 24 to dock with first interface 13.

[0017] The utility model has a switching design for the position of the hot air inlet, so that the hot air in the hot air pipe can be switched back and forth between having hot air and not having hot air. When the operator takes or places the product, the hot air is switched to the non-personnel side to avoid scalding the operator. Therefore, there is no need to stop and start the heater 24, which meets the physical requirements of the heater 24, avoids damage to the heater 24, increases the service life of the heater 24, saves costs, meets the requirements of the production rhythm, and has strong application value in production.
