[0041] like Figures 1 to 7 As shown, an embodiment of the present invention provides an automatic mold changing device, including an upper mold assembly 100, a lower mold assembly 200 and a storage table 300. It should be understood that the upper mold assembly 100, the lower mold assembly 200 and the storage table 300 are all installed on a frame 500.

[0042] Among them, the upper mold assembly 100 and the lower mold assembly 200 are arranged relatively to each other in the upper and lower directions. Specifically, a power system is arranged on the frame 500. The power system is a prior art and will not be described in detail here. The power system drives the lower mold assembly 200 to move up and down to achieve mold closing or mold opening. More specifically, the upper mold assembly 100 includes two relatively arranged upper side templates 120 and a locking mold part 110 located between the upper side panels. The lower mold assembly 200 includes a bottom mold 210 and two relatively arranged lower side templates 220 on the bottom mold 210. The upper template and the lower template are arranged adjacent to each other, and the foaming frame is placed on the bottom mold 210. When the mold is closed, the upper side template 120, the lower side template 220, the bottom mold 210, the locking mold part 110 and the mold core 400 on the locking mold part 110 form a foaming cavity.

[0043] Furthermore, the storage platform 300 is disposed on one side of the lower mold assembly 200 , and a plurality of mold cores 400 spaced apart along the Y-axis direction are placed on the storage platform 300 , and the plurality of mold cores 400 may be mold cores 400 of different models.

[0044] Furthermore, the upper mold assembly 100 includes a locking mold component 110, which can move along the X-axis direction to the top of the storage table 300, and the storage table 300 can move along the Y-axis direction so that one of the mold cores 400 on the storage table 300 can correspond to the locking mold component 110; the storage table 300 can also move upward so that the locking mold component 110 can be connected to the corresponding mold core 400, or support the mold core 400 connected to the locking mold component 110, so that when the locking mold component 110 is disconnected from the connected mold core 400, the mold core 400 can be placed on the storage table 300.

[0045] During operation, the operator first sets the required mold core 400 model on the control system, and further, the mold locking component 110 will move from the upper mold assembly 100 to the upper end of the storage table 300, and further, the storage table 300 will move along the Y-axis direction to make the selected mold core 400 correspond to the mold locking component 110 up and down, and further, the storage table 300 will move upward to connect the mold locking component 110 with the mold core 400, and further, the storage table 300 moves downward to disconnect from the mold core 400, and the mold locking component 110 carries the mold core 400 to the upper mold assembly 100.

[0046] When the mold core 400 needs to be replaced, the mold locking component 110 will carry the mold core 400 connected to it to the top of the storage table 300, and the storage table 300 will move along the Y-axis direction to make the mold core 400 correspond to the original position. Of course, in some applications, after the mold locking component 110 takes the mold core 400, the storage table 300 maintains this position unchanged to facilitate the subsequent replacement of the mold core 400. Further, the storage table 300 will move upward to support the mold core 400, and the mold locking component 110 will be disconnected from the mold core 400, and the mold core 400 will be placed on the storage table 300. Further, the storage table 300 moves downward to avoid it. Further, the storage table 300 moves along the Y-axis direction to make another mold core 400 correspond to the mold locking component 110. Finally, the storage table 300 moves upward to connect the mold locking component 110 to the mold core 400, thereby realizing the replacement of mold cores 400 of different models.
