Description
Technical Field
The utility model relates to a die-cut mould, in particular to die-cut mould that combines by the die-cut steel mould of aperture and window etching mould.
Background
Stamping dies are a special piece of tooling for processing materials (metallic or non-metallic) into parts (or semi-finished products). Stamping is a press working method in which a material is pressed with a die attached to a press at room temperature to be separated or plastically deformed to obtain a desired part, and there is often a problem of burrs in small hole blanking.
At present, the design of a common trimming die for punching small holes generally adopts two sets of dies, namely a blanking die and a small hole punching die. The workpiece is firstly blanked, and the blanking die adopts a conventional design. The small hole punching die adopts a workpiece positioning device with higher progress: increase special baffle, the baffle passes through the mould guide pillar or installs the little guide pillar direction on last mother, and baffle and little guide pillar adopt the high machining mode processing of precision, and the processing cost is higher. After a special guide plate is added, the height of a punch for punching a small hole is correspondingly increased, the running stability of the punch is reduced, and the possibility of damage is increased. Thus, a small-hole punch guided in this manner is often subject to damage. The use of two sets of dies also greatly increases the cost of die manufacture.

The technical proposal of the utility model for solving the technical problem is that:
a punching die combining a small-hole punching steel die and a window etching die comprises a lower die bottom plate, a lower die fixing plate, a lower die material supporting plate, an upper die fixing plate and an upper die plate which are stacked from bottom to top; the improved die is characterized in that a groove is formed in the middle of the upper die retainer plate, an upper die punch is embedded in the groove, an etching die is fixedly arranged on the lower surface of the upper die punch, and etching lines matched with the required appearance of a product are arranged on the lower surface of the etching die.
Further, a lower die punch is arranged on the lower die retainer plate, and the shape of the lower die punch is matched with that of the etching die.
Furthermore, the upper die punch is provided with a positioning pin, and the lower die retainer plate is provided with a positioning hole matched with the positioning pin.
Furthermore, a guide pillar is arranged on the lower die fixing plate, penetrates through the lower die material supporting plate and is matched with a guide sleeve on the upper die material supporting plate.
Furthermore, a spring is arranged between the upper die fixing plate and the upper die retainer plate.
The utility model discloses will need carry on die-cut semi-manufactured goods when using and place location on the lower mould drift, the starting equipment, the mould compound die, the mould asks the flitch downwards on the spring promotes, guide pillar on the lower mould and the guide pin bushing cooperation in last mould, go up the pinhole cooperation location on locating pin and the lower mould in the mould asks the flitch, the etching mould pushes down to product surface after, carves out required line on the product surface, goes up mould drift and lower mould drift cooperation simultaneously, surely die-cut 3D's effect on the product limit.
The utility model has the advantages that: (1) an etching die is embedded in the upper die for stamping, so that the die is high in precision, no burrs are generated, the size of a product is stable in the die-cutting processing process, and the service life of the die is long; (2) the small hole punching die and the etching die are combined and formed at one time, so that the processing procedures are reduced; (3) the mould is positioned by two steps, and the stability is good.
