[0039] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0040] Example 1

[0041] like Figure 1 — Figure 7 As shown, the insert core type stamping die of the present invention includes a mold clamping mechanism 100 , a base plate 200 , a lower conveying member 300 , a lower insert core 310 , an upper conveying member 400 , an inner insert core 410 and a first insert core 600 .

[0042] The mold clamping mechanism 100 is used for stamping products. One end of the base plate 200 is inserted into the mold clamping mechanism 100. The lower conveying member 300 is provided on the base plate 200. A lower insert 310 is slidably provided on the lower conveying member 300. The upper conveying member 400 is provided above the lower conveying member 300. An inner insert 410 is slidably provided on the lower end surface of the upper conveying member 400. A first insert 600 is inserted into the product. The lower conveying member 300 can insert the lower insert 310 into the product. The upper conveying member 400 can insert the inner insert 410 into the product, and the inner insert 410 is located at the first insert 600. Between the lower insert core 310, before stamping, people need to place the product in the clamping mechanism 100, and control the clamping mechanism 100 to make the bottom surface of the inner wall of the product flush with the bottom surface of the lower insert core 310, and exert a pressing force on the product, so that the product can be stably placed in the clamping mechanism 100; thereafter, the lower insert core 310 is inserted into the product through the lower conveying member 300, and then the first insert core 600 is inserted into the product, and the first insert core 600 is located directly above the lower insert core 310, and then the end of the product away from the lower conveying member 300 is blocked by the clamping mechanism 100, and then, The upper conveying member 400 extends the inner core 410 into the product and inserts the inner core 410 between the first core 600 and the lower core 310. In this way, the upper core supports the top of the product and the lower core 310 supports the bottom of the product. Afterwards, the mold clamping mechanism 100 punches the product. When the punching is completed, the upper conveying member 400 drives the inner core 410 to be pulled out of the product. At this time, after losing the support of the inner core 410, the first core 600 will fall onto the lower core 310, that is, the first core 600 will contact the inner wall of the product. The top is separated, and then people can move the first ferrule 600 out without contacting the inner wall of the product. After that, the mold clamping mechanism 100 drives the product to descend, and at this time the lower ferrule 310 is stationary relative to the bottom plate 200, so that the bottom surface of the lower ferrule 310 is separated from the bottom surface of the inner wall of the product. Then, people can move the lower ferrule 310 out of the product through the lower conveying member 300 without contacting the inner wall of the product. In this way, the first ferrule 600 and the lower ferrule 310 can be smoothly removed from the product without contacting the inner wall of the product, so as not to damage the inner wall of the product.

[0043] The lower conveying member 300 includes a lower guide rail 320 arranged on the base plate 200, and one end of the lower insert core 310 is provided with at least two lower sliders 330 slidably connected to the lower guide rail 320. A lower cylinder body 340 is provided on one side of the base plate 200, and a lower cylinder rod 350 is movably installed on the lower cylinder body 340. One end of the lower cylinder rod 350 is provided with a lower cylinder plate 360 ​​connected to the lower insert core 310. When working, people need to control the lower cylinder body 340, because the lower insert core 310 and the lower cylinder rod 350 are connected through the lower cylinder plate 360, so that the lower cylinder rod 350 can drive the lower insert core 310 and the lower cylinder plate 360 ​​to move in a directional manner along the trajectory of the lower guide rail 320. In this way, the lower insert core 310 can be inserted into the product or the lower insert core 310 can be removed from the product.

[0044] The upper conveying member 400 includes a top plate 420 and an upper guide rail 430 arranged on the bottom surface of the top plate 420. The top plate 420 and the bottom plate 200 are connected by a plurality of connecting columns 440. In this way, the top plate 420 and the bottom plate 200 can form a whole; one end of the inner core 410 is provided with at least two upper sliders 450 slidably connected to the upper guide rail 430, and the lower cylinder body 340 is provided with an upper cylinder body 460, and the upper cylinder body 460 is movably mounted with an upper cylinder Rod 470, one end of the upper cylinder rod 470 is provided with an upper cylinder plate 480 connected to the inner insert 410. When working, people need to operate the upper cylinder body 460. Since the first insert 600 is connected to the upper cylinder rod 470 through the upper cylinder plate 480, the upper cylinder rod 470 can drive the first insert 600 and the upper cylinder plate 480 to move in a directional manner along the trajectory of the upper guide rail 430. In this way, the first insert 600 can be inserted into the product or the first insert 600 can be removed from the product.

[0045] An inclined guide surface 411 is provided at one end of the inner ferrule 410 away from the upper cylinder plate 480 . The guide surface 411 allows the inner ferrule 410 to be smoothly inserted between the first ferrule 600 and the lower ferrule 310 .

[0046] like Figure 3 — Figure 10As shown, the mold clamping mechanism 100 includes a base 110 and a top seat 150 arranged just above the base 110, a lower template 120 is provided on the end surface of the base 110 facing the top seat 150, an upper template 160 is provided on the end surface of the top seat 150 facing the base 110, one end of the bottom plate 200 is inserted between the base 110 and the lower template 120, a baffle 180 is provided at the end of the lower template 120 close to the lower conveying member 300, the baffle 180 can prevent the product and the first insert 600 from moving toward the lower conveying member 300, a pressure plate 151 is provided between the upper template 160 and the top seat 150, wherein the pressure plate 151 is connected to the top seat 150 by bolts, and a spring (not marked in the figure) is provided between the upper template 160 and the pressure plate 151, specifically, a plurality of columns (not marked in the figure) are provided on the pressure plate 151, each column is inserted into the column, and one end of each column is away from the pressure plate 151 A baffle (not marked in the figure) is provided, and an active cavity (not marked in the figure) for the baffle to move is provided in the upper template 160, so that when the upper template 160 moves relative to the pressure plate 151, the upper template 160 will not separate from the pressure plate 151; guide ears 500 are provided on both sides of the product, and guide blocks 130 are provided on both sides of the lower template 120, and guide grooves 131 for inserting the guide ears 500 are provided on the guide blocks 130. The upper template 160, the lower template 120 and the two guide blocks 130 form a mold cavity 190, and an anti-slip cylinder body 140 is provided at the end of the lower template 120 away from the lower conveying member 300, and an anti-slip block 141 is movably provided on the anti-slip cylinder body 140, and the anti-slip block 141 passes through the lower template 120 and blocks one end of the product, and a lifting cylinder body 170 is provided on the base 110, and a lifting cylinder body 171 connected to the lower template 120 is movably provided on the lifting cylinder body 170.

[0047] When people place the product in the mold cavity 190, they need to pass the guide ear 500 through the corresponding guide groove 131 to realize the directional insertion of the product into the mold cavity 190. After that, they need to raise the lower template 120 by the lifting cylinder 170 until the bottom surface of the inner wall of the product is flush with the bottom surface of the lower insert 310. In this process, the upper template 160 can exert a certain pressing force on the product through the action of the spring, thereby further improving the product between the upper template 160 and the lower template. 120, and when one end of the product is against the stop frame 180, people can insert the lower ferrule 310 into the product, and then manually put the first ferrule 600 into the product, and make the first ferrule 600 be located just above the lower ferrule 310. After that, people can drive the anti-slip cylinder 140 to raise the anti-slip block 141 until the anti-slip block 141 blocks the product toward one end of the anti-slip cylinder 140, and then drive the inner ferrule 410 to be inserted into the first ferrule 60 0 and the lower ferrule 310, so that the first ferrule 600 can smoothly support the top of the product, and the lower ferrule 310 can smoothly support the bottom of the product. After that, the upper template 160 and the lower template 120 will stamp the surface of the product; and when the stamping is completed, the inner ferrule 410 is first pulled out from the product, so that the first ferrule 600 can smoothly fall onto the lower ferrule 310, that is, the first ferrule 600 is separated from the top surface of the inner wall of the product. After that, the anti-drop block 14 1 is lowered into the lower template 120 so that people can smoothly pull out the first ferrule 600 from the product from the end of the product near the anti-slip block 141. Thereafter, the lower template 120 is lowered by the lifting cylinder 170 to separate the bottom surface of the lower ferrule 310 from the bottom surface of the inner wall of the product. In this way, people can remove the lower ferrule 310 from the product. Finally, people can smoothly take the product out of the mold cavity 190 to prevent the first ferrule 600 and the lower ferrule 310 from damaging the inner wall of the product.

[0048] Furthermore, when the first ferrule 600 is inserted into the product and the anti-slip block 141 blocks one end of the product, the inner ferrule 410 will be inserted between the first ferrule 600 and the lower ferrule 310 and move toward the anti-slip block 141. During this process, the anti-slip block 141 will block the movement of the product and the first ferrule 600, that is, prevent the first ferrule 600 and the product from moving relative to the upper template 160 or the lower template 120, and ensure that the inner ferrule 410 can be smoothly inserted between the first ferrule 600 and the lower ferrule 310.

[0049] The first ferrule 600 is provided with a plurality of first grooves 412, and the lower ferrule 310 is provided with a plurality of lower grooves 311. The upper template 160 is movably provided with an upper module 161 adapted to the first grooves 412, and the lower template 120 is movably provided with a lower module 121 adapted to the lower grooves 311. When the inner ferrule 410 is successfully inserted between the first ferrule 600 and the lower ferrule 310, each upper module 161 is moved toward the product direction by hydraulic or pneumatic means until each upper module 161 is successfully embedded in the corresponding first groove 412. At the same time, each lower module 121 is moved toward the product direction by hydraulic or pneumatic means until each lower module 121 is successfully embedded in the corresponding lower groove 311. When the stamping is completed, the upper module 161 and the lower module 121 are again moved away from the product by hydraulic or pneumatic means. In this way, the upper module 161 and the lower module 121 can leave corresponding pits on the surface of the product.

[0050] Furthermore, the shapes of the first grooves 412 may be the same or different, and the shapes of the lower grooves 311 may be the same or different.

[0051] Example 2

[0052] like Figure 1 — Figure 10 As shown, this embodiment is a method for using a core-insertion stamping die, comprising the following steps:

[0053] Step 1: The guide ears 500 are moved along the trajectory of the guide grooves 131 to place the product in the mold cavity 190 between the upper mold plate 160 and the lower mold plate 120 until the end of the product abuts against the stop frame 180. The lower mold plate 120 is then raised by the lifting cylinder 170 until the bottom surface of the inner wall of the product is flush with the bottom surface of the lower insert 310. The upper mold plate 160 exerts a pressing force on the product, so that the product can be stably placed between the upper mold plate 160 and the lower mold plate 120.

[0054] Step 2: Insert the lower ferrule 310 into the product via the lower conveyor 300. Then, manually insert the first ferrule 600 into the product, positioning the first ferrule 600 directly above the lower ferrule 310 while ensuring that the end of the first ferrule 600 near the anti-dropout block 141 is not exposed outside the product.

[0055] Step 3: Operate the anti-slip cylinder 140 so that the anti-slip block 141 blocks the end of the product away from the lower conveying member 300 to prevent the product and the first ferrule 600 from moving relative to the upper template 160 or the lower template 120 during step 4.

[0056] Step 4: Insert the inner ferrule 410 into the product through the upper conveyor 400 and insert the inner ferrule 410 between the first ferrule 600 and the lower ferrule 310 so that the first ferrule 600 supports the top of the inner wall of the product and the lower ferrule 310 supports the bottom of the inner wall of the product;

[0057] Step 5: Each upper module 161 is inserted into the corresponding first groove 412 by hydraulic or pneumatic means. At the same time, each lower module 121 is inserted into the corresponding lower groove 311 by hydraulic or pneumatic means, so that the upper module 161 and the lower module 121 leave corresponding pits on the surface of the product. Afterwards, each upper module 161 and each lower module 121 are reset.

[0058] Step 6: After the stamping is completed, the upper conveyor 400 drives the inner ferrule 410 to be pulled out from the product to ensure that sufficient space for movement is reserved between the first ferrule 600 and the lower ferrule 310;

[0059] Step 7: Reset the anti-dropout block 141 into the lower module 121 by manipulating the anti-dropout cylinder 140 and manually remove the first ferrule 600;

[0060] Step 8: Lower the lower template 120 via the lifting cylinder 170 to separate the bottom surface of the lower ferrule 310 from the bottom surface of the product inner wall;

[0061] Step 9: Remove the lower insert 310 from the product through the lower conveying member 300 .

[0062] By using the above-mentioned insert-type stamping die, insert-type stamping of the product can be achieved, and after the stamping is completed, the first insert 600 and the lower insert 310 can be smoothly removed from the product without contacting the product, thereby not damaging the inner wall of the product.
