Abstract
The invention discloses a clamping plate molding die, which comprises an upper die, a lower die, an upper retainer plate and a lower retainer plate, wherein the upper retainer plate is arranged below the upper die; a groove is arranged in the lower end face of the upper retainer plate; a movable female die is arranged in the groove; an upper spring is arranged between the movable female die and the upper die; a cutting edge-shaped cavity is arranged in the movable female die; the lower retainer plate is arranged above the lower die; a lower spring is arranged between the lower retainer plate and the lower die; the lower retainer plate is provided with a through hole; the lower die is provided with a male die; and the male die is arranged in the through hole. According to the clamping plate molding die disclosed by the scheme of the invention, to-be-processed part is arranged on the lower retainer plate; the upper die is pressed downwards; the lower retainer plate moves down under the acting force of the upper retainer plate; the o-be-processed part is supported by the male die; a product appearance and a neck in a product are punched out at the periphery at a time at the same time under the punching action of the female die; the processing size is accurate, and the product molding quality is high.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to clamp mould in a kind of electric switch.
Background technology
Like clamp structure in the accompanying drawing 1 described electric switch, traditional processing method, first road is the profile that slightly punches out product, second road punches out the draw-in groove 51a in the middle of the product when essence is cut profile again; Because in the first road program, clamp structure and shape basic forming is when the second road program; During draw-in groove 51a in the middle of the die-cut product, can product be squeezed to both sides, causing in the draw-in groove 0.3mm to reserve limit 51b can't completely excise; Whole clamp physical dimension precision is relatively poor, influences product processing quality.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the high clamp mould of a kind of precision simple in structure, die-cut.
Technical solution of the present invention is achieved in that a kind of clamp mould, comprises upper and lower mould, upper and lower retainer plate; The said retainer plate of going up is arranged on the patrix below, is provided with groove in the retainer plate lower surface on this, is provided with movable master mold in the groove, is provided with upper spring between this activity master mold and the patrix; Be provided with the blade shape chamber in the said movable master mold; Said retainer plate down is arranged on the counterdie top, is provided with lower spring between following retainer plate and the counterdie, and this time retainer plate is provided with through hole; Said counterdie is provided with male model, and this male model is in the said through hole.
Preferably, also comprise pierce punch, have the cylindricality cavity in the said master mold; Said pierce punch one end is fixed in the patrix, and the other end extends in said cylindricality cavity.
Preferably, also be provided with guide pillar in the said counterdie; The said retainer plate of going up is provided with the guide hole that is used with guide pillar.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of clamp mould of the present invention; On retainer plate under to be processed the placement; Patrix is to pressing down, and following retainer plate moves downward under the active force of last retainer plate, and male model withstands to be processed; The while one-step punching goes out product design and product inner card cage all around under the die-cut effect of master mold, and processing dimension is accurate and the formed product quality is high.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is a clamp structure chart in the prior art;
Accompanying drawing 2 is the structural representation of a kind of clamp mould of the present invention;
Accompanying drawing 3 is a kind of movable master mold blade shape cavity configuration sketch map of the present invention;
Wherein: 1, patrix; 2, counterdie; 3, go up retainer plate; 3a, guide hole; 4, following retainer plate; 11, upper bolster; 12, upper padding plate; 12a, last installing hole; 13, train wheel bridge; 13a, upper spring; 14, bolt; 15, pierce punch; 21, die shoe; 21a, guide pillar; 22, lower bolster; 22a, following installing hole; 23, bottom plate; 23a, lower spring; 24, fastening bolt; 25, male model; 31, groove; 32, movable master mold; 32a, cutting edge die cavity; 32b, cylindricality cavity; 41, through hole; A, to be processed; 51, locating hole; 51a, draw-in groove; 51b, reservation limit.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a prior art clamp structure chart.
To be processed A is placed on down on the retainer plate 4; Patrix 1 moves downward; Be pressed into down on the retainer plate 4 until last retainer plate 3, following retainer plate 4 is operation downwards under the effect of last retainer plate 3 and lower spring 23a, and male model 25 stretches out and withstands to be processed A; Movable master mold 32 is cut into product in the cutting edge die cavity 32a of movable master mold 32 under the effect of upper spring 13a, accomplishes the die-cut of product.
For reducing the formed product operation, in a last operation, punch out the locating hole 51 on the product simultaneously, in patrix 1, also be provided with pierce punch 15, pierce punch 15 1 ends are fixed in the patrix 1, extend in the cylindricality cavity 32b that the other end has in movable master mold 32.
For guaranteeing patrix 1 and counterdie 2 closing precisions, on die shoe 21, also be provided with guide pillar 21a; The said retainer plate 3 of going up is provided with the guide hole 3a that is used with guide pillar 21a, and during matched moulds, guide pillar 21a inserts among the guide hole 3a.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
