Description
Technical field
The present invention relates to a kind of adjustable plating mould.
Background technology
Plating mould is that a kind of lead frame to electronic devices and components (a kind of metal strip) carries out the employed special tool of local continuous electroplating.Its effect is need to guarantee galvanized zone to plate, and does not need galvanized zone not allow to plate.Traditional plating mould, like Fig. 3 and shown in Figure 4, it is to be connected patrix 70, counterdie 20 with nut 80 with screw rod 10, through the position of adjustment nut 80, makes the distance between the silica gel circle 40 of patrix 70, counterdie 20 suitable, tightens nut 80 again and gets final product.This plating mould plating area edge is parallel with the lead frame edge, is the strip parcel plating.The width and the plating district in its plating district all can regulate to the distance at metal strip edge.Adjustment plating distinguish the metal strip edge apart from the time, earlier the trip bolt 60 of retaining ring 50 is back-outed a little, owing on the retaining ring 50 slotted hole is arranged, so retaining ring 50 can move.Running fix ring 50 makes its edge suitable to the distance at silica gel circle 40 edges of patrix, and the trip bolt 60 that tightens retaining ring 50 again gets final product.This mode has following shortcoming:
1. screw rod 10 is very long, and the centre is unsettled, so rigidity is very poor, therefore stressed easy deformation requires the rigidity of screw rod 10 fine, can only use metal screw to come to reduce distortion, but distortion is still bigger as far as possible.
2. metal screw conduction and not corrosion-resistant, use for some time after, can on screw rod, produce the metallic crystal thing, or be corroded and attenuate even rupture.
3. the screw rod that diameter is too little is difficult to the enough length of processing, and screw rod is too little, poor rigidity, stress deformation easily; Diameter is too big, can stop electroplating solution, and the position thickness of coating that causes being blocked descends.This is a pair of contradiction that can't overcome.
4. because the screw rod stress deformation is bigger, cause patrix 70, counterdie 20 right alignmenies poor, relative position is inaccurate.Cause the silica gel circle height of patrix 70, counterdie 20 inconsistent, have height difference H, the side that mould is low does not contact with metal strip 30 and causes the electroplating solution seepage, and the plating district enlarges, and causes plated item to scrap and increase the consumption of plating liquid medicine.
5. owing to patrix 70, counterdie 20 are plastics, screw rod 10 is metals, and its coefficient of thermal expansion is inconsistent.And plating mould at ordinary times normal temperature deposit, contact with the pyritous electroplating solution during use, repeatedly after the expansion-contraction, nut 80 can be loosening, causes the plating sector width out of hand.
Summary of the invention
The present invention seeks to overcome above-mentioned defective, a kind of adjustable consistent plating mould of right alignment of upper and lower mould is provided.
Another object of the present invention provides that a kind of rigidity is fine, distortion is little, and adjustable consistent plating mould of coefficient of thermal expansion.
The present invention can realize through following technical scheme: design a kind of adjustable plating mould; Comprise the ring-type patrix and with the ring-type counterdie of ring-type patrix equal diameters; Establish bulge loop at said ring-type patrix with the contacted side of said ring-type counterdie; On said bulge loop, be provided with a circle limbers, be provided with threaded hole, be provided with scrobicular ring in the side that contacts with said ring-type patrix of said ring-type counterdie in the outside of said limbers; On said ring-type counterdie, be provided with axial microscler adjustment hole with respect to said a chain for binding criminals pit; Ring-type patrix and ring-type counterdie are through the mode socket with transition fit of described bulge loop and scrobicular ring, and screw passes microscler adjustment hole and screws in the said threaded hole, and said ring-type counterdie and ring-type patrix are fixed together.
Among the present invention, on the outer ring of said ring-type patrix and ring-type counterdie, both sides, said limbers are respectively equipped with an adhesive tape mounting groove, and this adhesive tape mounting groove is used for closely contacting with the strip that needs parcel plating.In said adhesive tape mounting groove uniform distribution one circle adhesive tape fixed orifices, be used for adhesive tape is fixed in the said adhesive tape mounting groove.On said ring-type patrix outer ring, be provided with retaining ring.
Said screw is a plastic screw.
The present invention has adopted nested mode inside and outside ring-type patrix and the ring-type counterdie; At ring-type patrix and ring-type counterdie mating part, the external diameter of patrix equates with the internal diameter of counterdie, is nested together with the mode of transition fit; With the upper and lower mould trip bolt be fixed into as a whole after, whole rigidity is very good.Clamping once on processing units processes the external diameter of ring-type patrix, ring-type counterdie and the mounting groove of silica gel circle, so the height of the right alignment of upper and lower mould, two silica gel circles is very consistent, has avoided above-mentioned the 1st and the 4th 's shortcoming.In addition,, be out of shape for a short time, ring-type patrix, ring-type counterdie, comprise that screw allows employing with a kind of plastic working because the mould rigidity is fine, non-conductive, corrosion-resistant, avoided above-mentioned the 2nd and the 3rd 's shortcoming.Adopt plastic screw, the coefficient of thermal expansion between its ring-type patrix, ring-type counterdie and the plastic screw is in full accord, has avoided above-mentioned the 5th shortcoming.
Generally speaking, the present invention increases the mould rigidity because the ring-type patrix cooperates with the nested of ring-type counterdie greatly, and the present invention can adopt a clamping to process critical size, makes the precision raising.
