According to the continuous cutting-off and forming structure disclosed by the invention, two working procedures of cutting off and forming are integrated, so that the cost of the dies is reduced, the labor intensity of workers is reduced, the production efficiency is increased and the quality of the lead frame is ensured.
Description
Technical field
The present invention relates to the lead frame processing technique field, be specifically related to a kind of lead frame continuous cutting-off molding structure that lead frame cut-out and moulding two procedures can be united two into one.
Background technology
Lead frame cuts off with moulding and belongs to high-accuracy mould, when cutting off, due to the impact of the factors such as artificial, equipment, after cutting off, the size fluctuation of lead frame is larger, during moulding, due to the old-fashioned single die used, low the hanging down with the lead frame yield rate of efficiency is to affect the framework industry to be difficult to a progressive reason always.
For solving existing the problems referred to above in prior art, this patent provides a kind of new solution.
Summary of the invention
Problem to be solved by this invention is how a kind of lead frame continuous cutting-off molding structure is provided, lead frame length variations that this lead frame continuous cutting-off molding structure can solve lead frame while cutting off is large, the unsettled problem of otch, thereby improves the quality of products; Simultaneously, can unite two into one cutting off with the moulding two procedures, thereby enhance productivity.
To achieve the above object of the invention, the technical solution adopted in the present invention is: a kind of lead frame continuous cutting-off molding structure is provided, it is characterized in that: comprise front cut-out die, lower bolster, cut-out die block, material lift piece, concave template, stripper, cope match-plate pattern, pilot pin, cut-out punch, forming convax mould, guide pad, molding concave die and rear cut-out die; Wherein
Shut-off mechanism after described rear cut-out die and cut-out punch form; Described forming convax mould, molding concave die and concave template form molded lead frame mechanism; The location material lifting device that described pilot pin, guide pad and material lift piece form; Shut-off mechanism before described front cut-out die and forming convax mould form;
Described cut-out die block, concave template and molding concave die all are arranged on lower bolster; Described front cut-out die is fixed on and cuts off in die block, and the material lift piece is arranged on concave template, and guide pad is fixedly installed on molding concave die; Described forming convax mould is fixedly installed on the cope match-plate pattern below, and stripper is arranged on forming convax mould side and cope match-plate pattern below; Described cope match-plate pattern one end be provided with one with the cut-out punch of rear cut-out die cooperating, the other end be provided with one with the cutting edge of front cut-out die cooperating; Also be provided with pilot pin on cope match-plate pattern; Described rear cut-out die is fixedly installed between concave template and molding concave die; Described cut-out punch through stripper and the acting in conjunction of rear cut-out die on band; Described pilot pin acts on band through stripper.
According to lead frame continuous cutting-off molding structure provided by the present invention, it is characterized in that: described pilot pin at least is provided with two.
In sum, lead frame continuous cutting-off molding structure provided by the present invention has following advantage: 1, simple in structure, compact, reasonable; 2, owing to having adopted cut-out and moulding two procedures to be combined into the principle of a procedure, make the processing of mould and assembly precision uprise, the quality of product also uprises thereupon, has saved cost, boosts productivity, and has guaranteed the quality of lead frame; 3,, because the new construction that cuts into mould has reduced operation, the management cost on the operation and other auxiliary cost of manufacture have been reduced.
The accompanying drawing explanation
The structural representation of the cut-out side that Fig. 1 is lead frame continuous cutting-off molding structure.
The structural representation of the moulding side that Fig. 2 is lead frame continuous cutting-off molding structure.
Wherein, 1, front cut-out die; 2, lower bolster; 3, band; 4, cut off die block; 5, material lift piece; 6, concave template; 7, stripper; 8, cope match-plate pattern; 9, pilot pin; 10, cut off punch; 11, forming convax mould; 12, guide pad; 13, molding concave die; 14, rear cut-out die.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, this lead frame continuous cutting-off molding structure comprises front cut-out die 1, lower bolster 2, cut-out die block 4, material lift piece 5, concave template 6, stripper 7, cope match-plate pattern 8, pilot pin 9, cuts off punch 10, forming convax mould 11, guide pad 12, molding concave die 13 and rear cut-out die 14; Wherein, described rear cut-out die 14 and cut-out punch 10 form rear shut-off mechanism; The molded lead frame mechanism that described forming convax mould 11, molding concave die 13 and concave template 6 form; The location material lifting device that described pilot pin 9, guide pad 12 and material lift piece 5 form; Shut-off mechanism before described front cut-out die 1 and forming convax mould 11 form; Described cut-out die block 4, concave template 6 and molding concave die 13 all are arranged on lower bolster 2; Described front cut-out die 1 is fixed on and cuts off in die block 4, and material lift piece 5 is arranged on concave template 6, and guide pad 12 is fixedly installed on molding concave die 13; Described forming convax mould 11 is fixedly installed on cope match-plate pattern 8 belows, and stripper 7 is arranged on forming convax mould 11 sides and cope match-plate pattern 8 belows; Described cope match-plate pattern 8 one ends be provided with one with the cut-out punch 10 of rear cut-out die 14 cooperatings, the other end be provided with one with the cutting edge of front cut-out die 1 cooperating; Also be provided with pilot pin 9 on cope match-plate pattern 8; Described rear cut-out die 14 is fixedly installed between concave template 6 and molding concave die 13; Described cut-out punch 10 through stripper 7 and rear cut-out die 14 actings in conjunction on band 3; Described pilot pin 9 acts on band 3 through stripper 7.Described pilot pin 9 is provided with 4.
During use, lead frame band 3 is guided through mould by the groove on guide pad 12 and material lift piece 5, when mould moves downward for the first time, pilot pin 9 positions through lead frame, material lift piece 5, material lift piece 5 is moved downward by stripper 7 effects, then by the cutting edge on forming convax mould 11 and 1 effect of front cut-out die, lead frame is cut off to form and cut off a mouthful A, make molded lead frame by forming convax mould 11 and molding concave die 13 and concave template 6 effects simultaneously.Again because mould moves upward, material lift piece 5 lifts lead frame from molding concave die 13 and concave template 6 upper surfaces, again through moving downward next time, cut off punch 10 and rear cut-out die 14 lead frame is cut off and forms a cut-out mouthful B, the cut-out that repetitive process like this has just formed lead frame is carried out together with moulding.
Although by reference to the accompanying drawings the specific embodiment of the present invention is described, in the claim limited range of this patent, the protection that those skilled in the art do not need various modifications that creative work can make or distortion still to be subject to this patent.
