When the first moving part 22 moves close to the lower die assembly 3, one first inclined surface 221 of the first moving part 22 acts on one second inclined surface 321, and the other first inclined surface 221 acts on the other second inclined surface 321, so that the first moving part 22 simultaneously drives the two second moving parts 32 to move towards directions away from each other to shape the workpiece 200.
Specifically, one second moving member 32 moves along the third direction X1, the other second moving member 32 moves along the fourth direction X2, the two second moving members 32 respectively act on two frames of the workpiece 200 opposite to each other along the third direction X1, one second moving member 32 shapes one of the frames toward the third direction X1, and the other second moving member 32 shapes the other frame toward the fourth direction X2.
Referring to fig. 1, 5 and 6, in an embodiment, the lower die assembly 3 further includes a positioning element 36, the positioning element 36 is disposed on the lower die base 31, and the positioning element 36 is used for abutting against the workpiece 200 to limit the position of the workpiece 200 on the lower die base 31.

In the embodiment of the present application, the number of the positioning elements 36 is four, two of the positioning elements 36 are disposed at one end of the workpiece 200 along the third direction X1 at intervals, the other two positioning elements 36 are disposed at the other end of the workpiece 200 along the third direction X1 at intervals, and all four workpieces 200 abut against the frame of the workpiece 200 to limit the workpiece 200. Preferably, the two positioning members 36 located on the same side of the workpiece 200 are respectively close to two end portions of the workpiece 200, and the second moving member 32 is located between the two positioning members 36.

In one embodiment, lower die assembly 3 further includes a controller (not shown) and an inductor 35.
The sensor 35 is provided on the lower mold base 31, and the sensor 35 is used for detecting whether the first moving member 22 moves to the target position. Specifically, the sensor 35 is disposed between the two second moving parts 32, and a sensing area of the sensor 35 faces upward and is opposite to the first moving part 22. When the first moving member 22 moves close to the lower die assembly 3, the end of the first moving member 22 enters the sensing area of the sensor 35, and the sensor 35 can detect the position of the first moving member 22 relative to the lower die assembly 3.
The controller is arranged on the lower die base 31, the controller is electrically connected with the sensor 35 and the first driving member 23, and the controller can control the first driving member 23 to act according to the information detected by the sensor 35. For example, when the first moving member 22 moves close to the lower die assembly 3, the first moving member 22 drives the second moving member 32 to move, and when the sensor 35 detects that the first moving member 22 moves to the target position, which indicates that the shaping of the workpiece 200 by the second moving member 32 is completed at this time, the controller controls the first driving member 23 to stop moving and to remove the driving force to the first moving member 22, and at this time, the first moving member 22 stops moving along the first direction Z1, so as to prevent the first moving member 22 from driving the second moving member 32 to excessively shape the workpiece 200, thereby making the size of the workpiece 200 inconsistent with the requirements.
In one embodiment, the lower mold base 31 is provided with a slide groove 38 along the third direction X1, and the second moving member 32 is slidably provided in the slide groove 38. When the first moving part 22 drives the second moving part 32 to move, the sliding groove 38 can guide the second moving part 32 to move, and the moving precision and stability of the second moving part 32 are improved.
As shown in fig. 6, in one embodiment, the lower mold assembly 3 further includes an elastic member 37, and the elastic member 37 connects the lower mold base 31 and the second moving member 32. The elastic member 37 is used to generate an elastic force in the third direction X1 or the fourth direction X2 between the lower mold base 31 and the second moving member 32 to return the second moving member 32. When the first moving member 22 moves to the target position and the control area controls the first driving element 23 to release the driving force applied to the first moving member 22, the restoring force of the elastic element 37 applied to the second moving member 32 can cause the second moving member 32 to drive the first moving member 22 to move along the second direction Z2 until the second moving member 32 returns to the initial position.
If the first driving member 23 is an air cylinder, specifically, when the first moving member 22 moves to the target position, the air outlet valve of the air cylinder is opened, the air cylinder loses the driving force for the first moving member 22, the first moving member 22 loses the driving force for the second moving member 32, and the second moving member 32 can drive the first moving member 22 to move along the second direction Z2 under the action of the elastic member 37.
In one embodiment, the second moving member 32 is provided with a guide groove 322, the guide groove 322 has an opening facing the lower mold base 31, and at least a part of the elastic member 37 is provided in the guide groove 322. One end of the elastic member 37 is connected to the bottom wall of the guide groove 322, and the other end of the elastic member 37 is connected to the lower mold base 31.
Alternatively, the opening of the guide groove 322 is directed toward the lower die base 31 in the third direction X1 or the fourth direction X2.
In the embodiment of the present application, the number of the elastic members 37 is two, one elastic member 37 is at least partially disposed in the guide groove 322 of one second moving member 32, and the other elastic member 37 is at least partially disposed in the guide groove 322 of the other second moving member 32. The guide grooves 322 of the two second moving members 32 are opened in opposite directions, and the two elastic members 37 can move the two second moving members 32 toward each other to be reset.
In one embodiment, the resilient member 37 is a compression spring.
