Description

Lens gasket processing cutting die

Technical Field

The utility model relates to an electronic material processing cutting die technical field, especially a camera lens gasket processing cutting die.

Background

The gasket is widely applied to various electronic products, and is of a combined structure of polycarbonate and double faced adhesive tape, wherein the double faced adhesive tape has a bonding effect, the PC has reinforcing and insulating effects, and the lens gasket is one of the gaskets.

The following situations can occur in the actual processing process of the lens gasket in the prior art:

1. the product structure and the shape determine that the product can be formed by two times, the A cutter waste suction mold forms an inner frame of the product, the B cutter punches the shape, the PC or PET material is a green environment-friendly flame-retardant polycarbonate film, the material elongation is 90 percent, the stretching strength is 55MPa, the product is deformed after punching due to the material characteristics and the product thickness (0.1-0.5 MM) and the product is small (the diameter range is 3-6 MM), and the material clamping problem is caused when the product is normally discharged;

2. the product size is little, and PC is thick, and die-cut sword can only adopt the interior straight outer oblique cutting die to carry out die-cut, though this scheme can solve the PC because receive the deformation that the extrusion of cutting edge produced, can't solve the problem of PC card mould.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that needs to solve provides a camera lens gasket processing cutting die, uses this kind of processing cutting die both to solve PC and receive the extrusion and the problem of warping, can solve the problem of PC card mould again.

The utility model provides a technical scheme of above-mentioned technical problem is: the utility model provides a lens gasket processing cutting die, the cutting die includes the die body, the top of die body is equipped with the blade, the downside of blade is equipped with the cavity, it is cotton that the cavity intussuseption is filled with the pad sword bubble, the height of blade adds 0.2~0.5mm for treating the processing material gross thickness, the contained angle of cavity inner wall and the vertical face of blade is 10~ 12.

As an optimized technical scheme of the utility model, the height of blade point adds 0.3mm for waiting to process the total thickness of material. The high design of blade point can solve the material extrusion deformation and the problem of card mould in the processing this moment.

As an optimized technical scheme of the utility model, the height of blade point is 0.5~1 mm.

As an optimized technical scheme of the utility model, the height of blade point is 0.7 mm.

As an optimized technical scheme of the utility model, the contained angle of the vertical face of cavity inner wall and blade point is 10. At the moment, the processing effect of the cutting die is optimal, the material to be processed cannot deform or wrinkle, and waste materials generated by processing cannot be left on the material to be processed.

Because the utility model discloses a behind such structure, effectively solved present widely used lens gasket card mould and product quality and efficiency problem, lens gasket production technology merges the production manufacturing process, has saved production facility and cost of labor, has effectively promoted product competitiveness.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the cutting die of the present invention comprises a die body 1, a blade 2 is disposed on the top end of the die body 1, a cavity 3 is disposed on the lower side of the blade 2, a foam pad 4 is filled in the cavity 3, and the height of the blade 2 is 0.2-0.5 mm of the total thickness of the material to be processed; the included angle between the inner wall of the cavity 3 and the vertical surface of the blade 2 is 10-12 degrees. The cutter pad foam 4 can be used for protecting the cutter edge 2; the utility model discloses effectively improve product quality and efficiency, also saved production facility and cost of labor simultaneously, effectively promoted product competitiveness.

The utility model discloses it is further, the height of blade edge 2 adds 0.3mm for waiting to process the total thickness of material. The high design of blade point can solve the material extrusion deformation and the problem of card mould in the processing this moment.

The utility model discloses it is further, the height of blade 2 is 0.5~1 mm.

The utility model discloses it is further, the height of blade 2 is 0.7 mm.

The utility model discloses it is further, the contained angle of 3 inner walls of cavity and the vertical face of blade edge 2 is 10. At the moment, the processing effect of the cutting die is optimal, the material to be processed cannot deform or wrinkle, and waste materials generated by processing cannot be left on the material to be processed.

As shown in FIG. 3, the PC is not deformed by the blade during the production process of the prior art inner straight cutting die, but the PC is jammed.

The production process in the prior art comprises the following steps: raw material → blanking → die cutting 1 → die cutting 2 → waste discharge → inspection → warehousing. The quality of products prepared by the inner straight knife mold in the prior art has the adverse effects of surface wrinkle, deformation or splicing and the like.
