[0018] The first embodiment of the present application is:

[0019] See also Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of an ultrasonic welding mold lower mold device according to the first embodiment of the utility model. Figure 2 is a schematic structural diagram of a positioning device according to a first embodiment of the utility model, Figure 3 It is a structural schematic diagram of a welding part of the first embodiment of the utility model.

[0020] The utility model provides an ultrasonic welding mold lower mold device: it includes a mold base 101, and also includes a positioning device, the positioning device includes a mold fixed block 102, a mold movable block 103 and a driving component, the driving component includes a cylinder 107 and a push-pull rod 108. The above-mentioned solution solves the problem that for a special automobile lamp structure, the lower mold of a general ultrasonic welding mold cannot meet the requirements of both fully positioning and supporting the parts in the mold and making the parts easy to take and place. It can be understood that this solution can also be used to solve the problem of making the movement of the mold movable block more stable.

[0021] In this embodiment, the driving assembly drives the mold movable block 103 and the mold fixed block 102 to close or separate, so that the welding part 106 can be taken and placed. At the same time, through the action of the first accommodating groove 104 and the second accommodating groove 105, the welding part 106 can be positioned and supported, thereby ensuring that the welding part 106 is positioned and supported while being easy to take and place.

[0022] The mold fixing block 102 is fixedly mounted on the mold base 101, and a first receiving groove 104 is provided on a side of the mold fixing block 102 away from the mold base 101. The mold movable block 103 is slidably mounted on the mold base 101, and a second receiving groove 105 is provided on a side of the mold movable block 103 away from the mold base 101. The welding part 106 is located in the first receiving groove 104 and the second receiving groove 105. The driving component drives the mold movable block 103 to move. The mold fixing block 102 is a block structure, and the cross-section of the first receiving groove 104 is rectangular. The mold movable block 103 has the same structure as the mold fixed block 102, and the second accommodating groove 105 has the same structure as the first accommodating groove 104. The driving component enables the mold movable block 103 to have a better movement effect. The driving component drives the mold movable block 103 and the mold fixed block 102 to close or separate, so that the welding part 106 can be taken and placed. At the same time, through the action of the first accommodating groove 104 and the second accommodating groove 105, the welding part 106 can be positioned and supported, thereby ensuring that the welding part 106 is positioned and supported while being easy to take and place.

[0023] Secondly, the cylinder 107 is fixedly installed on the mold base 101 and is located on one side of the mold base 101 close to the mold movable block 103; one end of the push-pull rod 108 is fixedly connected to the mold movable block 103, and the other end of the push-pull rod 108 is fixedly connected to the output end of the cylinder 107. The cylinder 107 is fixed to the mold base 101 by screws. The push-pull rod 108 is a round rod-shaped structure. The two ends of the push-pull rod 108 are respectively welded to the output end of the cylinder 107 and the side of the mold movable block 103. The push-pull rod 108 is driven by the action of the cylinder 107 to move along the axis of the cylinder 107, so that the push-pull rod 108 drives the mold movable block 103 to move, thereby achieving the movement effect of the mold movable block 103.

[0024] Again, a special-shaped hole 109 is also provided on one side of the mold fixing block 102. The special-shaped hole 109 passes through the mold fixing block 102. The special-shaped hole 109 is connected to the first accommodating groove 104. The special-shaped hole 109 is adapted to the raised portion of the welding part 106. Through the setting of the special-shaped hole 109, the raised portion of the welding part 106 can be fully positioned.

[0025] In this embodiment, when in use, the cylinder 107 is started, and the cylinder 107 drives the push-pull rod 108 to move in a direction away from the mold fixed block 102. One end of the push-pull rod 108 is fixedly connected to the mold movable block 103. The movement of the push-pull rod 108 drives the mold movable block 103 to move to a side away from the mold fixed block 102, and then the welding part 106 is placed in the first receiving groove 104 and the second receiving groove 105, and the convex part of the welding part 106 passes through the special-shaped hole 106. 09, and then start the cylinder 107 again, so that the cylinder 107 moves in the opposite direction, and pushes the mold movable block 103 toward the mold fixed block 102 through the push-pull rod 108 to fix the welding part 106. When the welding part 106 is welded, the mold movable block 103 is separated from the mold fixed block 102 through the cooperation of the cylinder 107 and the push rod again, and then the welding part 106 is taken out, thereby ensuring that the welding part 106 is positioned and supported while being easy to take and put.

[0026] The second embodiment of the present application is:

[0027] See also Figure 4 ,in Figure 4It is a schematic diagram of the overall structure of an ultrasonic welding mold lower mold device of the second embodiment of the utility model. On the basis of the first embodiment, the ultrasonic welding mold lower mold device of this embodiment further includes a linear rail 201.

[0028] In this embodiment, the linear rail 201 and the slide groove 202 cooperate with each other, so that the mold movable block 103 can be more stable when moving on the mold base 101 .

[0029] Among them, the linear rail 201 is fixedly installed on the mold base 101 and is located on the side of the mold base 101 close to the mold fixed block 102. The number of the linear rails 201 is two groups, and the two groups of linear rails 201 are symmetrically distributed along the center line of the mold base 101. The cross-section of the linear rail 201 is rectangular. Through the setting of the linear rail 201, the mold movable block 103 can be more stable when moving on the mold base 101.

[0030] Secondly, a slide groove 202 is further provided on one side of the mold movable block 103 close to the mold base 101, and the linear rail 201 is located in the slide groove 202. The distribution of the slide groove 202 is the same as that of the linear rail 201. Through the setting of the slide groove 202, the mold movable block 103 can be positioned when sliding on the linear rail 201.

[0031] In this embodiment, when the mold movable block 103 moves on the mold base 101 , the mold movable block 103 slides on the linear rail 201 through the slide groove 202 , so that the mold movable block 103 can be more stable when moving on the mold base 101 .
