[0016] The lower mold base 1 has a first receiving groove 11 and a reset groove 12 communicating with the first receiving groove 11 at its bottom. Two first L-shaped guide plates 31 are fastened to both sides of the first receiving groove 11. A slidable first driving plate 32 is located between the two first L-shaped guide plates 31 in the first receiving groove 11. A first abutment groove 323 is opened at one end of the bottom of the first driving plate 32. A reset block 121 is fastened to the reset groove 12. A reset post 122 is fastened to one end of the reset block 121. A first reset spring 123 is sleeved on the reset post 122. The first reset spring 123 elastically abuts against the inner wall of the first abutment groove 323 of the first driving plate 32 and the reset block 121. After the molding process is completed, the first reset spring 123 can quickly reset the first driving plate 32 to ensure the continuous working capability of the device. An L-shaped driving section 321 extends from one end of the top of the first driving plate 32, and an L-shaped pressing section 322 extends from the other end of the top of the first driving plate 32. A second receiving groove 324 is provided in the middle of the top surface of the first driving plate 32. A first driving block 33 is fastened to the top of the L-shaped driving section 321. A limiting plate 3211 is fastened to one side of the top of the L-shaped driving section 321. A limiting block 3212 extends from one side of the limiting plate 3211. A first forming template 34 is fastened to the side of the L-shaped pressing section 322. Two second L-shaped guide plates 35 are fastened to both sides of the second receiving groove 324. The second receiving groove 324 is located between the two second L-shaped guide plates 35 and houses a slidable second driving plate 36. A second abutment groove 361 is provided on one side of the second driving plate 36, and a reset rod 362 is provided in the second abutment groove 361. A second reset spring 363 is sleeved on one end of the reset rod 362. The second reset spring 363 elastically abuts against the reset rod 362 and one side wall of the second receiving groove 324. After the molding process is completed, the second reset spring 363 can quickly reset the second driving plate 36 to ensure the continuous working capability of the device and improve production efficiency. Specifically, the second drive plate 36 has a guide slope 364 on one side of its top, and two inclined grooves 365 on both sides of the second drive plate 36 that connect to the guide slope 364. The inserting knife assembly 4 includes an inserting knife block 41 that is fastened to the bottom of the upper mold base 2. A second drive block 42 that slides against the first drive block 33 is fastened to one side of the bottom of the inserting knife block 41. A limiting groove 43 that slides with the limiting block 3212 is opened on one side of the bottom end of the inserting knife block 41. Two inclined plates 44 that slide with the two inclined grooves 365 are also fastened to both sides of the bottom end of the inserting knife block 41. The cooperation between the limiting block 3212 and the limiting groove 43 plays a first limiting and guiding role, and the cooperation between the inclined plate 44 and the inclined groove 365 plays a second limiting and guiding role, making the device more stable and reliable during operation. Among them, the insert block 41 facing the second drive plate 36 is also provided with a sliding plate 411, which can slide and abut against the second drive plate 36 to ensure the smooth operation of the device. The first driving block 33 has a first abutting inclined surface 331 and a first vertical surface 332 connected to the first abutting inclined surface 331. The second driving block 42 has a second abutting inclined surface 421 and a second vertical surface 422 connected to the second abutting inclined surface 421. The first abutting inclined surface 331 and the second abutting inclined surface 421 slide against each other, and the first vertical surface 332 and the second vertical surface 422 slide against each other. During the molding process, firstly, the first abutting inclined surface 331 and the second abutting inclined surface 421 abut against each other. When the first abutting inclined surface 331 and the second abutting inclined surface 421 disengage, then the first vertical surface 332 and the second vertical surface 422 abut against each other to ensure that the insert block 41 has sufficient contact with the first driving block 33 and the second driving block 42, thereby ensuring that the first forming template 34 and the second forming template 37 fully press the workpiece 5. The first L-shaped guide plate 31, the second L-shaped guide plate 35, the first drive block 33 and the second drive block 42 are all made of copper and graphite composite material. The copper and graphite composite material has good wear resistance and self-lubrication, which effectively reduces frictional wear between parts, extends the service life of the device and reduces maintenance costs. like Figures 5-8 As shown, to better understand the working principle of this utility model, the workflow can be divided into five processes, as follows: The first process: such as Figure 5 As shown, the initial process is the initial state of this device. The first driving block 33 on the insert block 41 is above the second driving block 42. The first driving block 33 and the second driving block 42 are not in contact. First, the workpiece 5 is placed between the first forming template 34 and the second forming template 37 by other equipment or manual labor of the external mold. The second process: such as Figure 6 As shown, the upper mold base 2 is driven by the mold's driving component, causing it to move downwards. The upper mold base 2 then moves the bottom insert assembly 4 downwards accordingly. The second driving block 42 at the bottom of the insert block 41 contacts the first driving block 33 on the first driving plate 32, meaning the first abutting inclined surface 331 and the second abutting inclined surface 421 slide against each other. At this time, the second driving block 42 pushes the first driving block 33 to move to the left, causing the first driving plate 32 to move to the left on the first L-shaped guide plate 31. This allows the first forming template 34 to fully contact and adhere to the surface of the workpiece 5. Simultaneously, as the first driving plate 32 moves to the left, the second driving plate 36 also moves to the left, causing the second driving plate 36 to drive the second forming template 37 to move to the left. At the same time, the two inclined plates 44 at the bottom of the insert block 41 are initially aligned with the inclined grooves 365 on both sides of the second driving plate 36. The third process: such as Figure 7 As shown, the upper mold base 2 continues to move downward, and the second driving block 42 at the bottom of the insert block 41 contacts the first driving block 33 on the first driving plate 32. The mutual sliding contact between the first abutting inclined surface 331 and the second abutting inclined surface 421 is converted into mutual sliding contact between the first vertical surface 332 and the second vertical surface 422; the sliding plate 411 of the insert block 41 initially contacts the second driving plate 36. The fourth process: Figure 8 As shown, the upper mold base 2 continues to move downward, the first vertical surface 332 and the second vertical surface 422 slide and abut against each other, the sliding plate 411 of the insert block 41 slides and abuts against the guide slope 364 of the second drive plate 36, the insert block 41 pushes the second drive plate 36 to move to the right, so that the second drive plate 36 moves to the right on the second L-shaped guide plate 35, thereby bringing the second forming template 37 close to the first forming template 34. The second forming template 37 cooperates with the first forming template 34 to fully press the workpiece 5 on both sides, and finally completes the pressing and forming of the workpiece 5. In the fifth process, after the molding is completed, the upper mold base 2 is driven by the mold drive component to move upward, and the inserter assembly 4 moves upward accordingly. The sliding plate 411 disengages from the guide slope 364 of the second drive plate 36, and the second drive block 42 disengages from the first drive block 33. Under the action of elastic force, the second return spring 363 pushes the second drive plate 36 to reset, and the first return spring 123 pushes the first drive plate 32 to reset under the action of elastic force, until the first drive block 33 on the inserter block 41 moves above the second drive block 42 (i.e., as shown). Figure 1 (As shown in the image), waiting for the next molding operation.

[0017] Five processes complete one work cycle, thereby continuously pressing work on workpiece 5. The operation is simple, stable and reliable, the work process is smooth, and the forming qualification rate of workpiece 5 is high.
