Specific embodiment
With specific embodiment, the invention will be further described with reference to the accompanying drawing, referring to Fig. 1-4:
A kind of PDCPD nickel mould, upper mold 1 and lower die 2 including adaptation, lower die 2 is equipped with die joint 3 and inner flow passage 4, described
Lower die 2 is additionally provided with the seal groove 5 around the setting of 3 edge of die joint, is additionally provided with air discharge duct 6, air discharge duct 6 and interior stream on die joint 3
Road 4 is located at the two sides of die joint 3, i.e. air discharge duct 6 and inner flow passage 4 two sides that are located at forming cavity, in injection process, extra gas
Cognition is discharged into air discharge duct 6, to reduce the generation of bubble in formed product overshoot；The edge of the die joint 3 and sealing
The junction of slot 5 is equipped with the area Jian Hou, i.e., certain thickness is reduced in the edge of die joint 3, since the thickness of reduction is smaller, in figure
And it is not drawn into；After molding, gap will form on the edge of die joint 3, excessive gas will can further be discharged, reduce product
The maximum reduced thickness of the generation of bubble in forming process, the preferred area Jian Hou controls between 0.2-0.3mm, if being lower than
0.2mm exhaust effect is undesirable, if being higher than 0.3mm, is easy to cause raw material to overflow, influences molding effect.
It is equipped with electroforming nickel layer 7 on one side with 2 face of lower die in the upper mold 1, i.e., one layer of electricity is set in the cavity surface of upper mold
Cast nickel layer, the electroforming nickel layer 7 with a thickness of 6mm, electroforming nickel layer 7 takes shape in die surface by electroforming process, so that upper mold 1
On cavity surface be nickel model cavity, when molding, have surface not sticking to mould, it is thermally conductive uniformly, the face product A smoothness is good, the service life compared with
The high advantage of general mold.
A kind of electroforming manufacture craft of DCPD nickel mould, the lower die are poured by aluminium alloy, and by traditional handicraft into
Row finishing, upper mold is made by electroforming process, the specific manufacture craft of upper mold the following steps are included:
One, moulding is required to make electrode die according to design parameter；
Two, electrode die surface is cleaned, and is passivated processing, keep it blunt in one layer of electrode die surface formation
Change film, subsequent demoulding is facilitated to handle；
Three, prepare electroforming tank, electroforming liquid be filled in electroforming tank, and be put into electroformed nickel as anode, electroformed nickel for containing
Sulphur nickel cake is put into electrode die as cathode, is passed through electric current, using electrodeposit, carries out metal electricity in electrode die outer surface
Deposition continues ulking thickness, forms electroforming nickel layer；
Four, the electrode die for being covered with electroforming nickel layer is placed in rinse bath, cleans the electroforming solution of electrode die surface remaining,
It then takes out and is cleaned with water；
Five, baffle is added in electroformed nickel layer surface surrounding and fill back lining materials, mold framework in composition, i.e., to electroforming nickel layer
