Most of these components are molded by injection molds. Injection molds are a tool for producing plastic products. Air-conditioning panels are made of injection molds.

[0003] Existing molds used for the production of air-conditioning panels cannot automatically demold the molded parts. Usually, the molded parts are pried out of the mold cavity manually using tools. However, this demolding method is not only complicated and inefficient, but also easily damages the molded parts. Utility Model Content

[0004] In order to solve the technical problem that the molded parts cannot be demoulded automatically, the molded parts are usually pried out from the mold cavity manually using tools, which is inefficient and easily damages the molded parts. The utility model provides an injection mold for an air conditioner panel.

[0005] The utility model is implemented by the following technical scheme: an injection mold for an air-conditioning panel, comprising a lower mold, a mold cavity and an upper mold, the mold cavity is opened inside the lower mold, the upper mold and the lower mold are arranged correspondingly, both sides of the mold cavity are connected with injection pipes, a demolding mechanism is arranged at the bottom of the mold cavity, which is used for automatic demolding of the air-conditioning panel after injection molding, and a heat dissipation mechanism is arranged inside the upper mold, which is used for rapid cooling and molding of the air-conditioning panel after injection molding.

[0006] As a further improvement of the above scheme, the demoulding mechanism includes a top plate sliding inside the mold cavity and a mounting hole opened at the bottom of the mold cavity, and a mounting block corresponding to the mounting hole is provided on the lower surface of the top plate, and a spring is fixedly connected to the bottom of the mounting block.

[0007] Through the above technical solution, during injection molding, the injection material squeezes the top plate downward, so that the mounting block squeezes the spring into the mounting hole. After the injection molding is completed, the upper mold is moved out, and the spring returns to push the top plate out, thereby automatically demolding the molded workpiece and improving work efficiency.

[0008] As a further improvement of the above solution, a fixing frame fixedly installed inside the lower mold is provided below the mold cavity, an air bag is provided inside the fixing frame, the top of the air bag is connected to an air pipe, and the air pipe is connected to the bottom of the mold cavity.

[0009] Through the above technical solution, since the mounting block and the mounting hole are sealed, when the top plate moves down, the air inside it is squeezed into the airbag. Through the use of the fixing frame, the airbag will not collide, so that the internal pressure thereof increases. When the upper mold is moved out, the airbag releases the pressure, and the air returns to between the mold cavity and the top plate through the air pipe, quickly lifting the top plate, thereby further enhancing the demolding effect.

[0010] As a further improvement of the above scheme, the heat dissipation mechanism includes a cooling pipe arranged inside the upper mold, one end of the cooling pipe is connected to a water inlet pipe, and the other end of the cooling pipe is connected to a water outlet pipe, and the water inlet pipe and the water outlet pipe both pass through the top of the upper mold.

[0011] Through the above technical solution, coolant is transported to the cooling pipe through the water inlet pipe, which speeds up the heat dissipation after injection molding, improves the product molding speed, and speeds up the work efficiency.

[0012] As a further improvement of the above solution, the top plate is located below the injection tube, and the spring is simultaneously the bottom inner wall of the lower mold and the lower surface of the mounting block.

[0013] As a further improvement of the above solution, a guide column is fixedly connected to the top of the lower mold, and a sliding groove corresponding to the guide column is opened inside the upper mold.

[0014] Through the above technical solution, by setting the guide pillars and the slide grooves, the stability of the lower mold and the upper mold when closing the mold is improved, and the product quality is improved.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model squeezes the top plate downward through the injection molding material, so that the mounting block squeezes the spring into the mounting hole, and at the same time squeezes the air inside the spring into the airbag. Through the use of the fixing frame, the airbag will not collide, so that the internal pressure thereof is increased. After the injection molding is completed, the upper mold is moved out, and at the same time the spring is reset, the airbag releases the pressure, and the air returns to between the mold cavity and the top plate through the air pipe, so that the top plate is quickly lifted up. The design is convenient for automatic demoulding of the molded part, and at the same time it is not easy to cause tearing of the molded part, thereby improving the demoulding efficiency and demoulding reliability.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1 - Figure 3 An injection mold for an air-conditioning panel in this embodiment includes a lower mold 1, a mold cavity 2 and an upper mold 4. The mold cavity 2 is opened inside the lower mold 1, and the upper mold 4 is arranged corresponding to the lower mold 1. Injection pipes 6 are connected to both sides of the mold cavity 2. A demolding mechanism is arranged at the bottom of the mold cavity 2 for automatic demolding of the air-conditioning panel after injection molding. A heat dissipation mechanism is arranged inside the upper mold 4 for rapid cooling and molding of the air-conditioning panel after injection molding.

[0025] Please combine Figure 2 The demoulding mechanism includes a top plate 10 sliding inside the mold cavity 2 and a mounting hole 12 opened at the bottom of the mold cavity 2. A mounting block 11 corresponding to the mounting hole 12 is provided on the lower surface of the top plate 10, and a spring 13 is fixedly connected to the bottom of the mounting block 11.

[0026] During injection molding, the injection material squeezes the top plate 10 downward, so that the mounting block 11 squeezes the spring 13 into the mounting hole 12. After the injection molding is completed, the upper mold 4 is moved out, and the spring 13 is reset to push the top plate 10 out, thereby automatically demolding the molded workpiece to speed up work efficiency.

[0027] Please combine Figure 2 A fixing frame 14 fixedly installed inside the lower mold 1 is provided below the mold cavity 2, an air bag 15 is provided inside the fixing frame 14, the top of the air bag 15 is connected to an air pipe 16, and the air pipe 16 is connected to the bottom of the mold cavity 2.

[0028] Since the mounting block 11 is sealed with the mounting hole 12, when the top plate 10 moves downward, the air inside it is squeezed into the airbag 15. By using the fixing frame 14, the airbag 15 will not collide, so that the internal pressure thereof increases. When the upper mold 4 is moved out, the airbag 15 releases the pressure, and the air returns to between the mold cavity 2 and the top plate 10 through the air pipe 16, and the top plate 10 is quickly lifted up, thereby further enhancing the demoulding effect.

[0029] Please combine Figure 1 and Figure 3The heat dissipation mechanism includes a cooling pipe 8 arranged inside the upper mold 4, one end of the cooling pipe 8 is connected to a water inlet pipe 7, and the other end of the cooling pipe 8 is connected to a water outlet pipe 9, and the water inlet pipe 7 and the water outlet pipe 9 both pass through the top of the upper mold 4.

[0030] The cooling liquid is transported to the cooling pipe 8 through the water inlet pipe 7, so as to accelerate the heat dissipation after injection molding, improve the product molding speed and speed up the work efficiency.

[0031] Please combine Figure 2 The top plate 10 is located below the injection tube 6 , and the spring 13 is simultaneously on the bottom inner wall of the lower mold 1 and the lower surface of the mounting block 11 .

[0032] Please combine Figure 1 A guide column 3 is fixedly connected to the top of the lower mold 1, and a slide groove 5 corresponding to the guide column 3 is opened inside the upper mold 4.

[0033] By providing the guide pillars 3 and the slide grooves 5, the stability of the lower mold 1 and the upper mold 4 when they are closed is improved, thereby improving the product quality.

[0034] The implementation principle of an injection mold for an air-conditioning panel in the embodiment of the present application is as follows: when working, the upper mold 4 is molded with the lower mold 1 through the guide column 3, and then injection molding is carried out into the mold cavity 2 through the injection molding tube 6. The injection molding material squeezes the top plate 10 to move downward, so that the mounting block 11 squeezes the spring 13 into the mounting hole 12, and at the same time squeezes the air inside it into the air bag 15. Through the use of the fixing frame 14, the air bag 15 will not collide, so that the internal pressure thereof increases. After the injection molding is completed, the coolant is transported to the cooling pipe 8 through the water inlet pipe 7 to accelerate the heat dissipation after injection molding and improve the product molding speed. The upper mold 4 is moved out, and at the same time as the spring 13 is reset, the air bag 15 releases the pressure, and the air returns to between the mold cavity 2 and the top plate 10 through the air pipe 16, and the top plate 10 is quickly lifted up to achieve automatic demolding.
