Problems solved by technology

However, punching with a mold with a stripper plate, although its structure is simple, has the disadvantage that the stripper plate is difficult to arrange because of the large space required for the stripper plate
At the same time, due to the restriction of the strength of the unloading plate and the service life of the spring, this structure also has many shortcomings.

Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] This embodiment relates to a punching die that can be unloaded, such as figure 1 As shown in , it includes a lower die base 1, on which a punching die 3 is arranged, and a die hole not shown in the figure is arranged on the punching die 3. This unloadable punching die also includes an upper die base 2 provided with a punch 4, the punch 4 is arranged on the upper die base 2 via a punch holder 5, and the punch 4 corresponds to the punching die 3 The die hole is set, so that the punch 4 is combined with the die hole, and the workpiece 10 placed on the punching die 3 can be punched due to the relative movement between the upper die base 2 and the lower die base 1 hole processing.

Abstract

The invention provides a punching mold capable of achieving discharging. The punching mold comprises a lower mold holder provided with a female mold hole and an upper mold holder provided with a puncher pin; the puncher pin is arranged in a manner of corresponding to the female mold hole, and due to the relative motion between the upper mold holder and the lower mold holder, a product placed on the lower mold holder is punched; a discharging potion which is communicated with the female mold hole so as to enable blanks obtained after product punching to flow out of the female mold hole is formed in the lower mold holder; the mold further comprises a product compressing mechanism which is arranged on the lower mold holder and exerts compressing force to the product from the peripheral side of the puncher pin when the puncher pin is separated out of the product. According to the punching mold capable of achieving discharging, during punching, punched blanks can be discharged, and the quality of punching of the product can be ensured.

Description

technical field [0001] The invention relates to the field of die technology, in particular to a punching die that can be unloaded. Background technique [0002] Punching dies have been used more and more widely because of their high production efficiency. However, most of the existing punching dies do not have an unloading device for unloading the blanking of the punching hole. Difficulty in unloading after punching will cause the plane of the punched part to be uneven and the bright part to be uneven, resulting in A decline in the quality of the piece. In order to solve the above problems, in the prior art, a discharge plate is arranged on the periphery of the punch, and a spring is provided between the discharge plate and the backing plate of the upper die, so as to reduce the difficulty of unloading. However, punching with a mold with a stripping plate, although its structure is simple, has the defect that the stripping plate is difficult to arrange because the space re...
