A through hole 82 is opened at the center position of the upper die seat 8, and an electromagnet 83 is provided at the bottom of the upper die seat 8 for magnetically attracting the air-conditioning shell after punching; the punch 7 is fixed at the center position of the bottom of the movable seat 6, and the punch 7 is set to perform vertical reciprocating linear motion during the punching process, and is slidably connected with the through hole 82 and the blanking chute 32.

[0027] By setting a lifting component 10 for movably connecting the upper die seat 8 and the movable seat 6, when the movable seat 6 is lifted by the hydraulic cylinder 5, it is used to drive the upper die seat 8 to be lifted synchronously, and in the process of pressing the movable seat 6 downward, the elastic action of the spring 9 is cooperated, so that the upper die seat 8 cooperates with the lower die seat 3 to press the air-conditioning shell, avoid movement during the punching work, and ensure the punching accuracy; through the setting of the electromagnet 83, the punching parts are quickly adsorbed after the punching is completed, and automatic material removal is realized, which reduces manual intervention, improves the degree of automation of the production line, and reduces labor intensity.

[0028] like Figure 2 As shown, it also includes a joint 61, which is fixedly connected to the center position of the top of the movable seat 6. The output end of the hydraulic cylinder 5 passes through the cross section of the cantilever 2 and is fixedly connected with the joint 61, ensuring the effective transmission of power.

[0029] like Figure 2 As shown, it also includes a sliding sleeve 62, which is a cylindrical structure and has the same number as the guide rod 4. The sliding sleeve 62 is arranged inside the movable seat 6, and the internal channel runs through the upper and lower ends of the movable seat 6. The sliding sleeve 62 is slidably connected with the guide rod 4.

[0030] like Figure 2 As shown, a storage groove 31 is provided at the center of the top of the lower mold base 3 for clamping the air conditioner housing.

[0031] Through this arrangement, the positioning effect of the air conditioner housing is further improved and the punching accuracy is improved.

[0032] like Figure 3 As shown, the lifting assembly 10 includes: a fixed sleeve 11, which is fixedly connected to the top of the upper mold base 8, and an inner cavity 12 is opened inside the fixed sleeve 11. Two mutually symmetrical sliding grooves 13 are opened on the side wall of the inner cavity 12.

Two mutually symmetrically arranged stoppers 15 are vertically fixedly connected to the side wall of the sliding rod 14 near the bottom position, and the stoppers 15 are slidably connected with the sliding grooves 13.

[0033] During the lifting and lowering process of the upper die seat 8, the synchronous movement with the movable seat 6 is achieved through the cooperation and abutment between the stop block 15 and the end wall of the slide groove 13. When the upper die seat 8 abuts against the lower die seat 3, as the movable seat 6 continues to drive the punch 7 to descend, the stop block 15 slides inside the slide groove 13 without affecting the normal downward pressure of the movable seat 6.

[0037] When the electromagnet 83 protrudes from the bottom of the upper mold base 8, the air-conditioning shell is positioned by the electromagnet 83 and the lower mold base 3. The electromagnet 83 is subjected to excessive force, which is easy to cause wear. When the electromagnet 83 is completely sunken into the bottom of the upper mold base 8, the magnetic attraction on the air-conditioning shell is low, affecting the automatic demoulding effect. Therefore, through this setting, the normal operation of the electromagnet 83 is ensured while its service life is extended.

[0038] The technical solution provided by the utility model, when in actual use, firstly places the air-conditioning shell to be punched in the storage groove 31 on the top of the lower die seat 3 to ensure accurate positioning; subsequently, start the hydraulic cylinder 5, and its output end pushes the movable seat 6 downward, and at the same time, under the action of gravity, the upper die seat 8 is connected with the movable seat 6 through the lifting component 10 to achieve synchronous descent with the movable seat 6; when the movable seat 6 drops to a certain height, that is, the upper die seat 8 and the lower die seat 3 cooperate to clamp the air-conditioning shell, at this time, the spring 9 is in a compressed state, and a certain distance is maintained between the upper die seat 8 and the lower die seat 3, as the hydraulic cylinder 5 continues to work, the movable seat 6 and the punch 7 are pushed downward, and during the downward pressing process, the upper die seat 8 gradually approaches the lower die seat 3 through the elastic action of the spring 9, continuously pressing the air-conditioning shell, and The punch 7 continues to press down to punch the air-conditioning shell through the through hole 82 and the blanking groove 32; after the punching is completed, the hydraulic cylinder 5 is reset, and the movable seat 6 drives the upper die seat 8 to rise under the action of the lifting component 10; at the same time, the electromagnet 83 is energized to quickly absorb the punched air-conditioning shell and make it separate from the storage groove 31; then the electromagnet 83 is powered off, and the air-conditioning shell can automatically fall off from the mold. It is particularly noted that after completing a batch of punching operations, the blanking groove 32 and the mold surface should be cleaned in time to ensure that there is no residue; regularly check the wear of each component, especially the guide rod 4, slider 81, spring 9 and electromagnet 83 and other wearing parts, and replace them when necessary; maintain the hydraulic cylinder 5 and the lifting component 10 to ensure that they are working properly.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention.
