[0026] Figure 1 Schematic diagram of the structure of the template assembly in the aluminum-plastic film forming machine in one embodiment of the utility model, such as Figure 1 As shown, and refer to Figure 2 The embodiment of the utility model provides an aluminum-plastic film forming machine, including a template assembly 100, the template assembly 100 includes a fixed plate 110, a lower template 120 and an upper template 130, the fixed plate 110 is provided with a mold core 140 and an elastic member 150, the elastic member 150 is spaced apart from the mold core 140; the lower template 120 is arranged on one side of the fixed plate 110 and connected to the elastic member 150; the lower template 120 is provided with a through hole for the mold core 140 to pass through; the upper template 130 is arranged on a side of the lower template 120 away from the fixed plate 110, and is configured to reciprocate in a direction away from or close to the lower template 120; the upper template 130 is provided with a groove for accommodating the mold core 140 on a side facing the lower template 120.

[0027] When in use, the aluminum-plastic film 400 is placed between the lower template 120 and the upper template 130 and covers the through hole; the upper template 130 is controlled to move toward the lower template 120 until the upper template 130 contacts the lower template 120, and the aluminum-plastic film 400 is clamped between the lower template 120 and the upper template 130. The upper template 130 is controlled to continue to move, and the upper template 130 drives the aluminum-plastic film 400 and the lower template 120 to move toward the fixed plate 110, and the mold core 140 starts to punch the aluminum-plastic film 400; at the same time, the elastic member 150 starts to elastically contract, and the mold core 140 starts to insert into the groove. When the upper template 130 moves to the preset position, the punching depth reaches the required size. The upper template 130 is kept at this position for a period of time, and then the upper template 130 is controlled to move in a direction away from the fixed plate 110, and the elastic member 150 gradually recovers. After the elastic member 150 recovers to the initial state, the upper template 130 is continued to be moved, and the upper template 130 is separated from the lower template 120, and the aluminum-plastic film 400 gradually separates from the mold core 140. After the upper template 130 is completely separated from the aluminum-plastic film 400, the upper template 130 is continued to be controlled to move to a specified position, and the formed aluminum-plastic film 400 is taken out. It should be noted that the movement of the upper template 130 in this embodiment can be achieved by driving the motor 310, pneumatic driving, hydraulic driving, human driving, etc.

[0028] In this embodiment, the elastic member 150 is arranged so that the elastic member 150 can be elastically contracted when the lower template 120 is moved and held, so as to punch holes in the aluminum-plastic film 400. In addition, the elastic deformation property of the elastic member 150 is reasonably utilized to provide support for the lower template 120 during punching holes, so that the punching depth can be freely set within a specified punching depth range, thereby improving the flexibility and efficiency of production and reducing the cost of replacing the depth gauge.

[0029] In one embodiment of the utility model, the number of the elastic members 150 is multiple, and the multiple elastic members 150 are evenly arranged around the mold core 140, so that during the punching process, the elastic members 150 can provide uniform support for the lower template 120 to improve the punching effect.

[0030] Specifically, the elastic member 150 is a spring or elastic rubber, and one end of the elastic member 150 is fixed to the upper side of the fixing plate 110 or the lower side of the lower template 120. Alternatively, the two ends of the elastic member 150 are fixed to the upper side of the fixing plate 110 and the lower side of the lower template 120, respectively.

[0031] In one embodiment of the present utility model, the template assembly 100 further includes a first guide column 160, which is disposed on the fixed plate 110 and is located on the same side of the fixed plate 110 as the mold core 140. The lower template 120 is provided with a first guide hole 121, and the upper template 130 is provided with a second guide hole 131. The first guide column 160 passes through the first guide hole 121 and the second guide hole 131 in sequence, and the upper template 130 and the lower template 120 are slidably connected to the first guide column 160 respectively.

[0032] In this embodiment, since the lower template 120 and the upper template 130 both make reciprocating motion when used, in order to prevent the lower template 120 and the upper template 130 from offsetting during the reciprocating motion, a first guide column 160 is additionally provided. The first guide column 160 can limit the lower template 120 and the upper template 130 to move only along a preset direction, thereby ensuring the punching effect.

[0033] In one embodiment of the utility model, the lower template 120 is provided with an aluminum-plastic film placement area and a plurality of positioning pins 170 on one side facing the upper template 130, and the plurality of positioning pins 170 are arranged at intervals around the aluminum-plastic film placement area. The upper template 130 is provided with a plurality of positioning holes on one side facing the lower template 120, and the positioning holes are arranged in one-to-one correspondence with the positioning pins 170.

[0034] Since the area enclosed by the plurality of positioning pins 170 is the aluminum-plastic film placement area, the aluminum-plastic film 400 is placed between the plurality of positioning pins 170 during application, i.e., falls into the aluminum-plastic film placement area, thereby positioning the aluminum-plastic film 400 and improving the molding effect. The one-to-one correspondence between the positioning holes and the positioning pins 170 can ensure that the through holes on the lower template 120 correspond to the grooves on the upper template 130, thereby avoiding failure in punching holes.

[0035] In one embodiment of the utility model, the aluminum-plastic film forming machine also includes a frame 200 and a drive assembly 300, the drive assembly 300 is arranged on the frame 200, and the fixed plate 110 is fixedly arranged on the frame 200; the drive assembly 300 is configured to output vertical reciprocating motion, and the output end of the drive assembly 300 is connected to the upper template 130 to drive the upper template 130 to reciprocate vertically, approaching or moving away from the lower template 120.

[0036] like Figure 2As shown, in one embodiment of the utility model, the frame 200 includes a bottom plate 210, a top plate 220 and a plurality of second guide columns 230, the bottom plate 210 and the top plate 220 are spaced apart, and the two ends of the second guide columns 230 are respectively fixedly connected to the bottom plate 210 and the top plate 220, so that the frame 200 is a frame-shaped structure. The fixing plate 110 is arranged on the bottom plate 210, and the driving assembly 300 is arranged on the top plate 220.

[0037] In one embodiment of the utility model, the driving assembly 300 includes a motor 310, a transmission screw 320 and a moving part 330, the transmission screw 320 is connected between the moving part 330 and the motor 310, the transmission screw 320 is arranged in a vertical direction, and the transmission screw 320 is connected to the output end of the motor 310 so that the motor 310 drives the moving part 330 to reciprocate in the vertical direction through the transmission screw 320; the motor 310 is arranged on the top plate 220, and the moving part 330 is connected to the upper template 130.

[0038] When used, the motor 310 rotates, driving the transmission screw 320 to rotate, so that the moving member 330 moves on the transmission screw 320, thereby moving the upper template 130 and the lower template 120. In this way, it is only necessary to select the motor 310 as a motor 310 that can rotate forward and reverse, so that the transmission screw 320 can rotate forward and reverse, thereby realizing the reciprocating movement of the upper template 130. Specifically, the motor 310 is a servo motor 310, and the rotation speed of the motor 310 and the rotation time of the motor 310 are determined by the position mode of the servo motor 310 to achieve precise position control.

[0039] Furthermore, the moving member 330 includes a lead screw nut 331, a guide sleeve 332 and a mounting plate 333. The lead screw nut 331 is screwed onto the transmission lead screw 320; the guide sleeve 332 is slidably sleeved onto the second guide column 230, and one side of the guide sleeve 332 is connected to the lead screw nut 331; the mounting plate 333 is arranged on the lead screw nut 331 and is detachably connected to the upper template 130. The lead screw nut 331 is a cylindrical structure with a large axial dimension, so that the end of the lead screw nut 331 away from the motor 310 always moves in the lead screw nut 331. By setting the guide sleeve 332, the rotational freedom of the lead screw nut 331 can be constrained, so that the moving member 330 moves in a predetermined direction.

[0040] In one embodiment of the utility model, a speed reduction mechanism 340 or a speed change mechanism is connected between the motor 310 and the transmission screw 320. The speed reduction mechanism 340 or the speed change mechanism can be a gear reducer, a worm gear reducer, or a planetary gear transmission.

[0041] When this embodiment is used, the motor 310 outputs torque after starting, the reducer can increase the output torque, the screw converts the torque into a linear thrust and additional torque of the screw nut 331, the additional torque causes the screw nut 331 to have a tendency to rotate around the screw, and the guide sleeve 332 constrains the rotational freedom of the screw nut 331, so that the screw nut 331 moves in a straight line and drives the upper template 130 to move through the mounting plate 333.

[0042] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
