The upper mold set includes a cover plate 1, a clamping plate 2, a guiding pin 3 and a punch 4. The lower mold set includes: a guiding plate 5, a lower template 6, a lower backing plate 7 and a mold base 8. The upper mold set and the lower mold set move relative to each other to achieve mold closing or mold opening. As Figure 2 shown in the figure, it is the distribution of the strip in the mold. The punch 4 punches to separate the strip. As Figure 2 shown in the figure, the feeding or discharging of the metal mold is usually assisted by an external mechanism or manual labor, and it cannot be connected to the automated production line. In addition, if an additional auxiliary feeding and discharging mechanism is used, the cost of the production line will also increase. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a metal mold.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A metal mold includes: an upper mold set and a lower mold set. The upper mold set is provided with a driving mechanism, and the lower mold set is provided with a driven mechanism and a strip driving member connected to the driven mechanism. The strip driving member is provided with a strip pushing portion protruding from the working surface of the lower mold set. During the process of mold closing of the upper mold set and the lower mold set, the driving mechanism and the driven mechanism move relative to each other, and the driven mechanism is driven by the driving mechanism to drive the strip driving member to translate so as to drive the strip to translate to a predetermined position.

The strip driving member includes a first strip driving member arranged on the first movable block. The first insert knife is provided with a first driving surface, and the first guide rod is provided with a first driving structure corresponding to the first driving surface. The first driving surface drives the first driving structure to drive the first guide rod and the first movable block to slide.

[0008] Preferably, the first driving structure is a first roller arranged on the first guide rod, and the first driving surface includes a first driving inclined surface.

[0009] Preferably, the first driving surface further includes a first limiting surface connected to the first driving inclined surface.

The driven mechanism further includes: a second guide rail arranged in the lower die set at the discharging end of the die, a second guide rod arranged in the second guide rail, a second reset mechanism, and a second movable block connected to the second guide rod. The strip driving member includes a second strip driving member arranged on the second movable block. The second inserting knife is provided with a second driving surface, and the second guide rod is provided with a second driving structure corresponding to the second driving surface.

[0014] Preferably, the second driving surface further includes a second limiting surface connected to the second driving inclined surface.

[0015] Preferably, when the die is closed, the first inserting knife pushes the first roller forward, the first movable block drives the first strip driving member to hook the strip and translate it to the processing position of the punch. The second inserting knife pushes the second roller backward, the second movable block retreats to the starting position, and the punch cuts the strip to separate the product.

[0016] When the die is opened, the upper die set moves upward, the first inserting knife is separated from the first roller, the first movable block retreats to the starting position of feeding, the cutting punch is lifted. At the same time, the second inserting knife is separated from the second roller, the second movable block translates to the end position of pushing the material, and the product at the processing position is pushed out of the die.

[0018] Furthermore, the present utility model uses an inserting knife with a driving surface to drive the guide rod to translate, which has a simple structure and is easy to implement, and at the same time can achieve a relatively high-precision control.

[0019] Furthermore, the first set of feeding mechanism is used for feeding, and the second set of feeding mechanism is used for separating, realizing feeding at the feeding end and separating the product at the discharging end simultaneously. Description of the Drawings

Detailed implementation manners

[0032] The following embodiments given in conjunction with the accompanying drawings further illustrate the detailed implementation manners of the hardware mold of the present invention. The hardware mold of the present invention is not limited to the descriptions of the following embodiments.

[0033] As shown in FIG. 3, this embodiment provides a hardware mold, which includes: an upper die set 100 and a lower die set 200. The upper die set 100 is provided with a driving mechanism, and the lower die set 200 is provided with a driven mechanism and a strip driving member connected to the driven mechanism. The strip driving member is provided with a material pushing portion 227 protruding from the working surface of the lower die set 200. During the process of the upper die set 100 and the lower die set 200 being closed, the driving mechanism and the driven mechanism move relative to each other, and the driven mechanism 210 is driven by the driving mechanism to drive the strip driving member to translate so as to drive the strip to translate to a predetermined position.

[0034] As a specific implementation manner, as Figure 3a , Figure 3b and Figure 4 shown, the driving mechanism includes a first inserting tool 110 arranged on the upper die set 100. The driven mechanism includes: a first guide rail 211 arranged in the lower die set 200, a first guide rod 212 arranged in the first guide rail 211, a first reset mechanism 219a (as Figure 3b shown), and a first movable block 213 connected to the first guide rod 212. The strip driving member includes a first strip driving member 221 arranged on the first movable block 213. The first inserting tool 110 is provided with a first driving surface 111, and the first guide rod 212 is provided with a first driving structure corresponding to the first driving surface 111. The first driving surface 111 drives the first driving structure to drive the first guide rod 212 and the first movable block 213 to slide. The first reset mechanism is used to drive the first movable block 213 to reset. In this embodiment, the first reset mechanism is composed of a compression spring and a limiting rod. Of course, the first movable block 213 can also be reset by elastic members such as torsion springs and elastic sheets.

[0035] Further, the first driving structure is a first roller 214 arranged on the first guide rod 212. The first driving surface 111 includes a first driving inclined surface 1111. Of course, the first driving inclined surface 1111 can be a plane inclined relative to the die feeding direction or a curved surface. The first driving structure adopts a roller structure, which can reduce friction and make the sliding of the first guide rod 212 smoother.

[0036] Further, the first driving surface 111 further includes a first limiting surface 1112 connected to the first driving inclined surface 1111. The first limiting surface 1112 defines the stopping position of the first roller 214, ensures the moving distance of the strip driving member 220, and further ensures the strip conveying distance. At the same time, after the strip 300 is in place at the processing position, during the continued downward movement of the upper die set 100, the strip 300 is kept in position to ensure the accuracy of the processing position.

[0037] In this embodiment, the inclination and length of the first driving inclined surface 1111 are selected according to the feeding distance required. The length of the first limiting surface 1112 can also be selected as needed, as long as it maintains a certain distance during the downward or upward movement of the upper die set 100.

[0038] As an alternative embodiment, the first plug cutter 110 can be changed to a rack structure, and the follower mechanism can adopt a structure of a gear and a rack.

[0039] In this embodiment, the upper die set 100 includes a cover plate 101, a clamping plate 102, a guiding pin 103, and a punch 104. The first plug cutter 110 is arranged in the clamping plate 102 and is fixed by the cover plate 101 or directly fixed in the clamping plate 102. The punch 104 is used to cut off the strip.

[0040] In this embodiment, the lower die set 200 includes a lower die base 201, a lower backing plate 202, a lower template 203, a lower closing plate 204, and a lifter pin 205. The first guide rail 211 is arranged in the lower template 203, and the lower template 203 is provided with a space for the first movable block 213 to slide.

[0041] In this embodiment, the first plug cutter 110, the first guide rail 211, the first guide rod 212, and the first movable block 213 are arranged at the die feeding end, as shown in FIG. 3, Figure 5 As shown, the driving mechanism further includes a second plug cutter 130 arranged on the upper die set 100 at the die discharging end. The follower mechanism further includes: a second guide rail 215 arranged in the lower die set 200 at the die discharging end, and a second reset mechanism 219b (such as Figure 3bAs shown, a second guide rod 216 disposed within the second guide rail 215, and a second movable block 217 connected to the second guide rod 216. The tape driving member includes a second tape driving member 222 disposed on the second movable block 217. The second cutting tool 130 is provided with a second driving surface 131, and the second guide rod 216 is provided with a second driving structure corresponding to the second driving surface 131. The second driving surface 131 drives the second driving structure to drive the second guide rod 216 and the second movable block 217 to slide. The second reset mechanism is used to drive the second movable block 217 to reset. In this embodiment, the second reset mechanism 219b is composed of a compression spring and a limiting rod. As other alternative embodiments, elastic members such as torsion springs and elastic sheets can also be used as the reset mechanism for the second movable block 217.

[0042] Further, the direction in which the second cutting tool 130 drives the second guide rod 216 and the second movable block 217 to slide is opposite to the direction in which the first cutting tool 110 drives the first guide rod 212 and the first movable block 213 to slide. In this way, the first tape driving member 221 completes feeding during the mold closing process to position the material. After the punch 104 completes cutting, the second tape driving member 222 moves in the direction opposite to the feeding direction at this time, hooks the material about to be cut, and after the material cutting is completed, during the mold opening process, the second tape driving member 222 moves in the feeding direction to separate the cut material, enabling the material to enter the next working station.

[0043] Further, the second driving structure is a second roller 218 disposed on the second guide rod 216, and the second driving surface 131 includes a second driving inclined surface 1311. Similarly, the inclination and length of the second driving inclined surface 1311 are selected according to the feeding distance required. In this embodiment, the length of the second driving inclined surface 1311 is longer, so that the second tape driving member 222 can push the cut product to move a greater distance to send it out of the mold.

[0044] Further, the second driving surface 131 further includes a second limiting surface 1312 connected to the second driving inclined surface 1311 for limiting the position of the second roller 218.

[0045] In this embodiment, the first cutting tool 110, the first guide rail 211, the first guide rod 212, the first movable block 213, and the first tape driving member 221 constitute a first set of feeding mechanisms for feeding the tape to the processing position of the punch 104; the second cutting tool 130, the second guide rail 215, the second guide rod 216, the second movable block 217, and the second tape driving member 222 constitute a second set of feeding mechanisms for sending the cut product out of the mold.

[0046] Reference Figure 6 and Figure 7, the operation process of the hardware mold in this embodiment is as follows:

[0047] In the closed mold state, the upper mold set 100 moves downward, the first insert knife 110 pushes the first roller 214 forward (the feeding direction), the first movable block 213 drives the first tape driving member 221 to hook the tape 300 and translate it to the processing position of the punch 104. The second insert knife 130 pushes the second roller 218 backward (opposite to the feeding direction), the second movable block 217 retracts to the starting position, and the punch 104 cuts the tape 300 to separate the product.

[0048] In the open mold state, the upper mold set 100 moves upward, the first insert knife 110 separates from the first roller 214, the first movable block 213 retracts to the starting position of feeding, the cutting punch 104 is lifted. At the same time, the second insert knife 130 separates from the second roller 218, and the second movable block 217 translates to the end position of pushing the material, and pushes the product at the processing position out of the mold.

[0049] After the product is separated through the above mechanism in this embodiment, the product can be automatically fed into the next automatic process to connect with the automated production line; reduce the processing procedures, shorten the production cycle, lower the production cost, and improve the production efficiency.
