[0037] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] See also Figure 1-4 The present invention provides a fully automatic mechanical in-mold transfer transmission mechanism, comprising:

[0039] A lower die base 1 has a processing table 11 on its top for punching parts, and a through hole 12 for the inserting knife 51 and the cam slot plate 52 to pass through is opened on the top of the lower die base 1.

[0040] The tool holder 4 is pressed against the workbench 11 and the workpiece 1 is pressed against the workpiece 11. The tool holder 4 is pressed against the workbench 11 and the workpiece 1 is pressed against the workbench 11. The tool holder 4 is pressed against the workbench 11 and the workpiece 1 is pressed against the workbench 11.

[0041] It should be noted that, since two groups of inserting knife groups are provided in this device, and each group of inserting knife groups has two inserting knives 51, four through-holes 12 corresponding to the inserting knives 51 should be provided on the lower die base 1, thereby facilitating the penetration of the four inserting knives 51. Similarly, two cam slot plates 52 are provided. Therefore, the staff should open two through-holes 12 on the lower die base 1 for the cam slot plates 52 to penetrate, thereby ensuring the normal operation of the cam slot plates 52.

[0042] See also Figure 1-2And 4, a clamping component 2, which is symmetrically arranged on both sides of the processing table 11 and slidably connected to the lower mold base 1, for clamping and fixing the processing material on the processing table 11, the clamping component 2 includes two first slide rails 21 parallel to each other and located on the outside of the processing table 11, each first slide rail 21 is slidably connected with at least two first sliding blocks 22, a connecting rod 23 is provided between the two first sliding blocks 22 located on the same horizontal line, and a plurality of chucks 24 for clamping and fixing the material are fixed on the outer wall of the connecting rod 23, and a slope 241 is provided on the end of each chuck 24 close to the processing table 11, and the material is lifted and grabbed by the slope 241.

[0043] Specifically, the staff fixedly connected a first slide rail 21 on both sides of the processing table 11. In this embodiment, preferably, the staff set two slidable first sliding blocks 22 on each first slide rail 21, and a connecting rod 23 is passed through the two first sliding blocks 22 on the same side of the two first slide rails 21, and one end of the connecting rod 23 extends to the outside of the first sliding block 22 on one side, which is convenient for subsequent connection with the horizontal moving component 3. The staff sleeves and installs a plurality of chucks facing the processing table 11 on the outer wall of the two connecting rods 23 between the corresponding two first sliding blocks 22. 24. During operation, the insert 51 descends with the upper die base 4, and the transition section 511 on the outer wall of one side thereof contacts the corresponding first sliding block 22, thereby pushing the two first sliding blocks 22 located on the same first slide rail 21 to move apart, thereby making the chuck 24 away from the processing table 11, so that the upper die base 4 and the lower die base 1 are not disturbed by the outside world when they are closed. Similarly, when the upper die base 4 rises, the transition section 511 gradually loses its squeezing control on the first sliding block 22, and the first sliding block 22 returns to its initial position. The chuck 24 and the horizontal moving assembly 3 are used to clamp and move the sheet to achieve continuous stamping of the sheet.

[0044] It should be noted that each chuck 24 is provided with a slope 241 at one end close to the processing table 11. The slope 241 can enable the head of the chuck 24 to drive the sheet to rise and separate from the positioning pin on the mold, thereby avoiding the positioning pin from getting stuck and affecting the normal production and processing of the device.

[0045] In some embodiments, the staff can also set a limit block at both ends of the first slide rail 21. Through the setting of the limit block, it can effectively ensure that the first sliding block 22 does not separate from the first slide rail 21 when sliding, avoiding unnecessary trouble to the staff during normal production and processing work.

[0046] See also Figure 1 、 2, 4, 7, a horizontal moving component 3, which is fixedly connected to the clamping part 2 and is used to drive the clamping part 2 to move in the horizontal direction of the lower mold base 1. The horizontal moving component 3 includes two second slide rails 31 located on one side of the clamping part 2 and vertically distributed to one of the first slide rails 21. The tops of the two second slide rails 31 are slidably connected to a mounting plate 33 through second sliding blocks 32. A third slide rail 34 is provided on the upper surface of the mounting plate 33 along its length direction, and third sliding blocks 35 with the same number as the connecting rods 23 are slidably connected to the third slide rail 34. One end of each connecting rod 23 extends into the corresponding third sliding block 35, and a cam shaft 36 is provided on the side away from the two third sliding blocks 35.

[0047] Specifically, the staff set two second slide rails 31 parallel to each other and perpendicular to the first slide rail 21 on the side of the first slide rail 21 on one side, and a mounting plate 33 parallel to the first slide rail 21 is set on the two second slide rails 31. The bottom of the mounting plate 33 is provided with two second sliding blocks 32 respectively connected to the second slide rails 31. The horizontal movement of the mounting plate 33 is achieved by sliding the two second sliding blocks 32 on the second slide rails 31. At the same time, a third slide rail 34 is also provided on the mounting plate 33 along its length direction, which is consistent with the first slide rail 21 in the above embodiment. The operator also arranges a third sliding block 35 on the third slide rail 34, the number of which is the same as the connecting rod 23 (in this embodiment, preferably, two third sliding blocks 35 are provided). As mentioned in the above embodiment, one end of the connecting rod 23 extends from one of the first sliding blocks 22. Therefore, the end of the extended connecting rod 23 is connected and fixed to the corresponding third sliding block 35. The horizontal movement of the mounting plate 33 drives the horizontal movement of the connecting rod 23, and then, multiple chucks 24 clamp and fix the sheet, and move to the next step to complete the subsequent processing work.

[0048] It should be noted that, in this embodiment, cam shafts 36 are also installed on both ends of the mounting plate 33, and the cam shafts 36 are arranged in the sliding groove 521, so that the horizontal moving component 3 can be moved back and forth in the horizontal direction.

[0049] In some embodiments, consistent with the above embodiments, the staff can also set a limit block or an elastic block at both ends of the second slide rail 31 and the third slide rail 34 to ensure that the second sliding block 32 and the third sliding block 35 are not offset or misaligned, thereby extending the service life of the device, thereby increasing the fault tolerance rate, avoiding the workload of frequent maintenance required by the staff, and bringing a better use and work experience to the staff.

[0050] See also Figure 1-3 , an upper die base 4 is relatively arranged just above the lower die base 1.

[0051] Specifically, in this embodiment, the upper die base 4 is arranged above the lower die base 1 and both are fixedly installed on the stamping machine. The bottom of the upper die base 4 is fixedly installed with a punch corresponding to the processing table 11 and used to punch on the sheet. When the upper die base 4 and the lower die base 1 are closed, the punch will contact the processing table 11, thereby stamping the sheet on the processing table 11.

[0052] See also Figure 1 、 2 , 3, 5, 6, a vertical moving component 5, which is fixedly connected to the bottom of the upper die base 4, and can partially pass through the lower die base 1, and is respectively slidably connected to the clamping part 2 and the horizontal moving component 3, for driving the two relatively arranged clamping parts 2 to move toward or away from each other, the vertical moving component 5 includes two symmetrically arranged groups of inserting knives and a slot plate group, each group of inserting knives includes two relatively arranged inserting knives 51, each inserting knife 51 is slidably connected to the side wall of the corresponding first sliding block 22 through a pulley 221 fixedly connected to the first sliding block 22, and each side wall of the inserting knife 51 has an arc-shaped transition section 511, and the corresponding pulley 221 slides against the transition section 511, the slot plate The group includes two symmetrically arranged cam slot plates 52, both of which are fixedly connected to the bottom of the upper mold base 4. A sliding slot 521 with a diamond cross-section is provided on the side wall adjacent to the two cam slot plates 52, and the corresponding cam shaft 36 slides. The sliding slot 521 enables the horizontal moving component 3 to drive the clamping component 2 to move in the horizontal direction. The two ends symmetrically arranged in each sliding slot 521 are movably connected to a check block 53. The cam slot plate 52 is provided with a number of accommodating slots 522 that is the same as the number of the check blocks 53. Each accommodating slot 522 accommodates and fixes a reset spring 54 fixedly connected to the corresponding check block 53. The check block 53 has an inclined slope, and the slope faces the movement direction of the cam shaft 36.

[0053] Specifically, the staff fixedly installed four plungers 51 at the bottom of the upper mold base 4, and each two adjacent plungers 51 are in opposite directions. When the upper mold base 4 drives the plungers 51 to move downward, the transition section 511 on one side wall of the plunger 51 will slide against the pulley 221 installed on the first sliding block 22, thereby pushing the first sliding block 22 away from each other through the arc-shaped transition section 511 to move in a preset direction, thereby controlling the separation of the two connecting rods 23, so that the chuck 24 is away from the processing table 11, thereby ensuring that the mold is not affected by external factors when closing.

[0054] Furthermore, the staff also installed two cam slot plates 52 at the bottom of the upper mold base 4, and a diamond-shaped (similar to a parallelogram) sliding slot 521 was opened on the side wall where the two cam slot plates 52 are close to each other. The cam shaft 36 is accommodated in the sliding slot 521. When the mold is closed, the cam shaft 36 is located at the top of the sliding slot 521. When the mold is in the maximum open state, the cam shaft 36 is located at the bottom of the sliding slot 521. When the mold is closed / opened, the cam shaft 36 will slide along the path opened by the sliding slot 521. Since the sliding slot 521 is a diamond-shaped design, it can drive the horizontal moving component 3 to reciprocate in the horizontal direction, thereby controlling the gradual advancement of the sheet on the processing table 11, thereby realizing continuous stamping of the sheet.

[0055] It should be noted that in the sliding groove 521, the staff set a check block 53 at both ends. The function of the check block 53 is to limit the movement trajectory of the camshaft 36 so that it does not rebound, thereby ensuring the normal operation of the mold when opening / closing. Among them, the two corresponding check blocks 53 on the same cam groove plate 52 are provided with a accommodating groove 522, and a reset spring 54 connected to the corresponding check block 53 is provided in each accommodating groove 522. Its function is that when the camshaft 36 passes through the check block 53, it will squeeze the check block 53 so that it can pass through. When it completes the passage, the reset spring 54 drives the check block 53 to rebound to the initial position, completing the limitation of the camshaft 36 that has passed through, preventing it from moving back, and ensuring the normal operation of the device.

[0056] In some embodiments, the check block 53 is preferably configured as a triangle, with one side of the hypotenuse facing the direction of travel of the camshaft 36 to facilitate the passage of the camshaft 36. In other embodiments, the staff can also use check blocks 53 of other shapes, thereby providing the staff with more options.

[0057] The working principle and use process of the present invention: After the present invention is installed:

[0058] 1. The worker places the blank on the processing table 11. At this time, the camshaft 36 is located at the lowest end of the sliding groove 521;

[0059] 2. When the mold begins to close, the camshaft 36 moves upward along the sliding groove 521 and then begins to move to the left, simultaneously driving the chuck 24 on the connecting rod 23 to move to the left. At this time, the insert 51 also begins to move downward and squeezes the first sliding block 22, causing the chuck 24 to move away from the processing table 11, thus closing the mold.

[0060] 3. When the stamping die is opened, the insert 51 rises and gradually loses its pressure on the first sliding block 22. The connecting rod 23 returns to its original position, driving the chuck 24 to clamp the blank. Then, the camshaft 36 moves downward and then to the right, pulling the connecting rod 23 to the right. Driven by the chuck 24, the blank moves forward one step and enters the next process.

[0061] 4. The mold is closed again and the second step is repeated.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
