Abstract
The utility model relates to a secondary ejector for a punch die. The secondary ejector has a vital function particularly when the punch die punches small pieces; after the secondary ejector is used for the punch die, when a primary ejector ejects a product out of a die cavity, the secondary ejector can continuously eject the product to separate from the primary ejector if the product is adhered to the primary ejector; and when the punch die is provided with the secondary ejector, the product is not adhered to the primary ejector any more to ensure that the punch die is hardly damaged and effectively protected, and the production efficiency is improved.
Description
Technical field:
The utility model is a kind of punch die secondary ejector; Can embody it when especially punch die is towards smallclothes and have important function; After punch die has been used the secondary ejector; After an ejector ejected mold cavity to product, if product also is bonded on ejector, the secondary ejector will continue the product top from an ejector; Punch die has had on the no longer sticking ejector of secondary ejector product, to guarantee that punch die is not easy to be broken, ensures that effectively the life-span of punch die is longer, enhances productivity.
Background technology:
At present, punch die is the ejector punch die of blanking (go up) for once generally, can not be stained with mould towards the punch die of big part because of conducting oneself with dignity towards part; But because part is lighter, if on the material greasy dirt is arranged, dust etc. just are prone to be bonded on ejector when the smallclothes punching out; An ejector is washed out easily; Or before sweeping away a mould, fall down and drop on the counterdie, will cause mould to damage the lost of life like this.
The utility model content:
The purpose of the utility model provides a kind of punch die secondary ejector, realize ejector fail the product top from the time, the secondary ejector again the product top from an ejector.
Its objective is such realization; In Fig. 1: make bar and be connected with block hitting, block hitting with make bar 2 times and be connected, make bar and be connected for 2 times with an ejector; Stopping screw, back-moving spring, secondary ejector all are installed in ejector; The secondary ejector is below back-moving spring, and stopping screw is fixed on ejector, makes back-moving spring between stopping screw and secondary ejector.
The course of work below in conjunction with embodiment Fig. 1, a kind of punch die secondary ejector of explanation: when patrix is in when treating worker's state, sweep away the backlash part in die for the first time, push up and make bar to 2 times through playing block hitting that bar connects; Make bar for 2 times and push up to an ejector again and from die, product is ejected, small and light because of product, be bonded at when not falling down on ejector by greasy dirt; As sweep away once more and will break mould; So just can not break mould through dress secondary ejector on ejector, when ejector not when part ejects die, the secondary ejector is got lodged in ejector by product; Back-moving spring is in compressive state between stopping screw and secondary ejector; After an ejector ejects die to product, also be bonded on ejector like product, back-moving spring is just brought into play reset response
The top so just leave an ejector to the product top again, recycles the situation that operation just mould can not occur breaking to top secondary ejector like this.
Beneficial effect:
Punch die adds that the such product of secondary ejector just can not be bonded on ejector again, avoids mold damage, and punch die has had the secondary ejector, and its life-span obtains reliable guarantee, and operating efficiency also is improved, and is comprehensive lifting.
Description of drawings:
The concrete structure of the utility model is provided by following examples and accompanying drawing:
Fig. 1, be the primary structure sketch map of the utility model.
Among Fig. 11, top mold frame, 2, make bar, 3, block hitting, make bar 4,2 times, 5, ejectors, 6, stopping screw, 7, back-moving spring, 8, the secondary ejector, 9, die.
The specific embodiment:
Below in conjunction with Fig. 1 the concrete condition of the utility model is described,, is swept away the backlash part in die (9) for the first time when patrix is in when treating worker's state; Bar (4) is made to 2 times in block hitting (3) top through playing bar (2) connection; Make bar (4) for 2 times and push up again to an ejector (5) and from die (9) product is ejected, small and light because of product, be bonded at when not falling down on the ejector (5) by greasy dirt; As sweep away once more and will break mould; Just can not break mould so go up dress secondary ejector (8) through an ejector (5), when an ejector (5) not when ejecting die (9) towards part, secondary ejector (8) is got lodged in the ejector (5) by product; Back-moving spring (7) is in compressive state between stopping screw (6) and secondary ejector (8); After an ejector (5) ejects product die (9), also be bonded on the ejector (5) like product, back-moving spring (7) just will be brought into play the reset response top to top secondary ejector (8); So just leave an ejector (5) to the product top again, recycle the situation that operation just mould can not occur breaking like this.
Claims (1)
1. punch die secondary ejector, it by top mold frame, play bar, block hitting, make bar for 2 times, ejector, stopping screw, back-moving spring, secondary ejector, a die forms; It is characterized in that: make bar and be connected with block hitting; Block hitting with make bar 2 times and be connected; Make bar for 2 times and be connected with an ejector, stopping screw, back-moving spring, secondary ejector all are installed in ejector, and the secondary ejector is below back-moving spring; Stopping screw is fixed on ejector, makes back-moving spring between stopping screw and secondary ejector.
