Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a die for stamping multiple products. Background Technology

[0002] Existing stamping dies are mainly customized according to the stamping processing requirements of sheet metal products. This means that one set of stamping dies can only be used for processing one type of sheet metal product. For multiple types of sheet metal products in the same series, multiple sets of stamping dies need to be designed according to the stamping processing position. This results in high equipment costs for sheet metal processing. Furthermore, using multiple sets of stamping dies to stamp different types of sheet metal products affects the ease of processing sheet metal products, thereby affecting the processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a mold that can meet various stamping processing needs and realize stamping processing of various products.

[0004] The purpose of this utility model is achieved as follows: A die for stamping multiple products includes an upper stamping die and a lower stamping die. The lower stamping die has a forming boss on its top. The upper stamping die includes an upper die base and an upper die plate connected together. A forming groove is provided on the bottom of the upper die plate corresponding to the forming boss. A forming processing space for accommodating the workpiece exists between the forming groove and the forming boss. The die is characterized by further including a first push plate and a second push plate. The upper die plate has a first stamping groove group and a second stamping groove group communicating with the forming groove. A first stamping rod group is provided within the first stamping groove group, and a second stamping rod group is provided within the second stamping groove group. A first pneumatic assembly and a second pneumatic assembly are fixed at both ends of the bottom surface of the upper mold base, respectively. The first pneumatic assembly is driven to one end of the first push plate, so that the other end of the first push plate is movably disposed between the upper mold base and the upper template. The other end of the first push plate abuts against the upper end of the first stamping rod assembly, and the lower end of the first stamping rod assembly extends into the forming groove. The second pneumatic assembly is driven to one end of the second push plate, so that the other end of the second push plate is movably disposed between the upper mold base and the upper template. The other end of the second push plate abuts against the upper end of the second stamping rod assembly, and the lower end of the second stamping rod assembly extends into the forming groove.

[0005] This mold, capable of stamping multiple products, features two sets of pneumatic components and two push plates. During operation, it allows for simultaneous or non-simultaneous pushing of both push plates, or the selection of pushing either the first or second push plate. This adjustment of the two stamping rod sets satisfies the diverse stamping requirements of various product workpieces. Furthermore, a single mold can fulfill multiple stamping needs, eliminating the need to waste time switching between different molds and improving overall processing efficiency when processing multiple product workpieces.

[0006] The objective of this utility model can also be achieved by the following technical measures: Specifically, the upper template is provided with a first recess and a second recess. The bottom surface of the first recess has the first stamping groove group, and the other end of the first push plate extends into the first recess and abuts against the upper end of the first stamping rod group. The bottom surface of the second recess has the second stamping groove group, and the other end of the second push plate extends into the second recess and abuts against the upper end of the second stamping rod group. The first recess can play a good guiding and limiting role in the movement of the first push plate, so that the first push plate can stably push the first stamping rod group downward. Similarly, the second recess can play a good guiding and limiting role in the movement of the second push plate, so that the second push plate can stably push the second stamping rod group downward.

[0007] Specifically, the first stamping rod assembly includes a first large stamping rod and two first small stamping rods, and the first stamping groove assembly includes a first large stamping groove and two first small stamping grooves. Each of the first large and first small stamping grooves is provided with a mounting platform. The upper part of both the first large and first small stamping rods is provided with an outer ring edge, which rests on the mounting platform. The lower parts of both the first large and first small stamping rods extend into the forming groove. This allows the first stamping rod assembly to simultaneously meet the processing requirements of stamping different shapes. Furthermore, the cooperation between the outer ring edge and the mounting platform ensures that the first large and first small stamping rods are stably supported in their respective stamping grooves, which is beneficial for the stable operation of the first large and first small stamping rods.

[0008] Specifically, the second stamping rod group includes at least one second small stamping rod, and the second stamping groove group includes at least one second small stamping groove. The second small stamping rod is placed in the second small stamping groove and the lower part of the second small stamping rod extends into the forming groove; the implementation effect is good.

[0009] Furthermore, the bottom of the stamping die is connected to a receiving seat, and a first large blanking hole is opened on the stamping die corresponding to the position of the first large stamping rod. A conveyor belt is provided on the receiving seat, and the conveyor belt is located below the first large blanking hole. This allows the waste material punched down by the first large stamping rod to fall through the first large blanking hole onto the conveyor belt of the receiving seat, and then be conveyed to a designated position by the conveyor belt. The implementation effect is good.

[0010] Specifically, the lower stamping die has a first small blanking hole corresponding to the position of the first small stamping rod, and the receiving seat is also provided with a first guide cylinder. The upper opening of the first guide cylinder is located below the first small blanking hole, and the lower opening of the first guide cylinder is located above the conveyor belt. The first guide cylinder can effectively connect the first small blanking hole and the conveyor belt, so that the waste material falling through the first small blanking hole can also be stably conveyed to the conveyor belt of the receiving seat, and the implementation effect is good.

[0011] Specifically, the lower stamping die has a second small blanking hole corresponding to the position of the second small stamping rod, and the receiving seat is also provided with a second guide cylinder. The upper opening of the second guide cylinder is located below the second small blanking hole, and the lower opening of the second guide cylinder is located above the conveyor belt. The second guide cylinder can effectively connect the second small blanking hole and the conveyor belt, so that the waste material falling through the second small blanking hole can also be stably conveyed to the conveyor belt of the receiving seat, and the implementation effect is good.

[0012] Specifically, the bottom surface of the upper mold base is further provided with a first mounting groove and a second mounting groove. A first wear-resistant plate is fixed on the first mounting groove, and a second wear-resistant plate is fixed on the second mounting groove. The bottom surface of the first wear-resistant plate abuts against the upper surface of the first push plate, and the bottom surface of the second wear-resistant plate abuts against the upper surface of the second push plate. The hardness of the wear-resistant plate is less than that of the corresponding push plate, which reduces the noise generated by the friction between the push plate and the wear-resistant plate when the push plate moves, and also improves the service life of the push plate and the upper mold base.

[0013] Specifically, the first pneumatic component includes a solenoid valve and a drive cylinder. Both the drive cylinder and the solenoid valve are fixed on the bottom surface of the upper mold base. One end of the drive cylinder is connected to the solenoid valve, and the other end of the solenoid valve is connected to an external air source. The drive shaft of the drive cylinder is fixedly connected to one end of the first push plate. The solenoid valve controls whether the drive cylinder is inlet or not, thereby controlling the operation of the drive shaft of the drive cylinder. This is relatively simple to implement and has a good implementation effect.

[0014] The beneficial effects of this utility model are as follows: (1) This mold for stamping multiple products can be set with two sets of pneumatic components and two push plates. During operation, it can be selected to push the two push plates simultaneously or not, or to push the first push plate or the second push plate, so as to adjust the two stamping rod groups and thus meet the different stamping processing requirements of multiple product workpieces. Furthermore, multiple stamping processing requirements can be achieved with one set of molds, that is, there is no need to waste time switching between different molds, which improves the overall processing efficiency when processing multiple product workpieces.

[0015] (2) The first stamping rod group can simultaneously meet the processing requirements of stamping different shapes; at the same time, through the cooperation of the outer ring edge and the mounting platform, the first large stamping rod and the first small stamping rod are stably supported in the corresponding stamping groove, which is conducive to the stable operation of the first large stamping rod and the first small stamping rod.

[0016] (3) The first guide cylinder can effectively connect the first small discharge hole and the conveyor belt, so that the waste material falling through the first small discharge hole can also be stably conveyed to the conveyor belt of the receiving seat, and its implementation effect is good.
