Description
Technical field
The utility model relates to a kind of silica gel mould, specifically for the punching stretch forming of silica gel product.
Background technology
We find in the punch forming of long-term silica gel product, for needing the silica gel product of stretching and punching press all to need two techniques, at least need use two mold, for realizing drawing and forming and blanking operation; So the production efficiency of this series products becomes very low; Meanwhile, silica gel product, when the demoulding, when such silica gel product is with the demoulding extremely difficult during barb shape time especially, easily causes the drawing crack of product own to damage.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, and provide a kind of silica gel to fit blanking die, it can disposable stretching and punching blanking forming; Its knockout course is very reliably convenient simultaneously, ensure that yields, improves production efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of silica gel laminating blanking die, comprise base plate and head, described base plate is fastened on work bench of punch press by bolt and pressing plate, base plate is equipped with punch retainer, and head is built with die shank, and the lower end of die shank is connected to die block, punch retainer is provided with punch stripper, be provided with spring between punch retainer and punch stripper, the lower end of die block is connected to add-in card, and the lower end of add-in card is connected to concave template;
Be provided with punch assemblies in described punch retainer, punch retainer and stripper offer concentric through hole; Described punch stripper is connected with punch retainer by guide pillar; Described concave template is fixed by screws in below die block; Described concave template is also connected with knockout rod, and described knockout rod passes die shank, die block, and add-in card connects with concave template;
Described concave template is arranged die assembly; Described die assembly comprises the chute be opened on concave template, and the notch both sides of chute arrange limited block; In chute, bilateral symmetry is slidably installed two die slide blocks, and described die slide block is connected with the groove arm of chute respectively by coil tension spring; Described two groove follower in opposite directions one side are inclined-plane; Described punch assemblies comprises the punch body be fixed in punch retainer, and punch body top is punch briquetting, and the cross section of punch briquetting is trapezoidal, and its trapezoidal slope is consistent with the slope of described die slide block; Described punch body and punch briquetting are arranged in concentric pylone that described punch retainer and stripper are offered;
Also comprise guiding mechanism, described guiding mechanism comprises lead and fairlead, fairlead and base plate interference fit, lead and die block interference fit, and lead and fairlead, by the ball interference fits of guide pin bushing inside, can slide up and down.
Further: between described base plate and presser's station, Buffer Unit is set, described Buffer Unit comprises spaced top board and fagging, vertically be arranged side by side multilayer rubber cushion between top board and fagging, separated by iron plate between rubber mat.
Silica gel laminating blanking die described in the utility model, it has the following advantages:
1, the utility model structure is simple, and whole mould on punch press, can carry out stretching and punching to part to be processed, disposal molding by clamping very reliably, simple to operate, improves operating efficiency; Specifically operationally, head moves down, and makes the downward matched moulds of concave template; Concave template pressure punch stripper during matched moulds, time punch assemblies punch briquetting on reveal, silica gel is sent into recessed in-molded; After die sinking, knockout rod hits the product after pushing away completion type and is convenient to fetch, and forms the de-material of disposable punching stretch shaping;
2, punch assemblies of the present utility model and die assembly have passed through special design, punch briquetting and the mutual action of chute is utilized to coordinate, complete the production of product, the easy demoulding of the utility model, knockout course during production can rely on naturally resetting of slide block and ramp structure to realize product reliably to be departed from by die position; Product can not be damaged; The utility model is when matched moulds, and die slide block horizontally slips along chute; During the demoulding, die assembly moves upward, and die slide block is slided by coil tension spring forward, the smooth demoulding of product;
3, be connected with top board below base plate of the present utility model, between top board and fagging, be provided with multilayer rubber cushion; When mould relatively compresses up and down and starts, rubber blanket under top board starts compression, when reaching shaping compacted position, pressure-pad-force can not change, reach pressure-pad-force reach certain numerical value after substantially constant effect, keep constant, avoid the phenomenon that pressure-pad-force increases with the increase of stroke, improve product surface quality, reduce percent defective.
