Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Examples

Referring to fig. 2 to 3, the embodiment discloses a punching die for punching a through hole in an EVA/TPT product, including a moving die holder 2 and a fixed die holder 4, where the moving die holder 2 is supported on the fixed die holder 4, specifically, a vertically extending guide rod 18 is disposed on the fixed die holder 4, and the moving die holder 2 is installed on the guide rod 18 in a manner that it can be lifted up and down through a guide sleeve. This movable mould seat 2 and cover half seat 4 select for use the die holder of high counterpoint precision, and during the in-service use, both have high counterpoint precision in vertical direction. The movable die holder 2 is connected with a driver 6, and the movable die holder 2 is driven to lift up and down so as to be matched with or demoulded from the fixed die holder 4; a product station 8 is arranged on the fixed die holder 4, and the product station 8 is used for placing a product to be punched; the movable die holder 2 is provided with a male die 10, the fixed die holder 4 is provided with a female die 12 matched with the male die 10, and the male die 10 and the female die 12 are arranged oppositely along the vertical direction and are respectively positioned at two sides of the product station 8. Specifically, when the fixed die holder 4 and the movable die holder 2 are machined, the fixed die holder and the movable die holder are respectively integrally formed into a first installation part and a second installation part at positions opposite to each other in the vertical direction. Usually, the first mounting part and the second mounting part are both recessed grooves, the fixed die holder 4 and the movable die holder 2 with the first mounting part and the second mounting part have high alignment precision when leaving factory, and the male die 10 and the female die 12 are respectively mounted on the second mounting part and the first mounting part through screws (namely, feeding) when being mounted and used subsequently.

The punching die of above structure, during the in-service use, the mould arrangement is installed to the lathe, and the product that needs punch a hole is arranged in product station 8 and is started driver 6 afterwards, and driver 6 application of force and drive movable mould base 2 and push down and cover half seat 4 compound die, and terrace die 10 and die 12 cooperation during the compound die, the position that the terrace die passed the product is punched out the through-hole. Here, the product passes through product station 8 under the effect of traction force in succession, and simultaneously, the mould is closed the drawing of patterns in the alternative compound die of movable mould seat 2 and the fixed mould seat, punches a plurality of through-holes on the product.
