Abstract
The utility model relates to an automatic cutting die structure of wasting discharge of cell-phone back protection film. Frame waste material need be drawn upward to arrange after die-cut in current course of working, still need draw the material area row of holes waste material down, arranges twice waste material totally, occupies the rate of utilization of board, leads to production efficiency lower. The utility model discloses an upper cutting die and lower tool board of mutually supporting, upper cutting die on set up the sword frontal area, one side in sword frontal area sets up the waste material kicking block, the height that highly is higher than of waste material kicking block the height in sword frontal area, lower tool board on open and to have the blanking hole that matches with waste material kicking block size, the lower part in blanking hole is that the blanking is regional. The utility model can directly eject the waste to the blanking area by utilizing the waste ejecting block on the upper cutting die; the waste discharge step is reduced, and the production efficiency is improved; because the waste can be directly pushed downwards, a layer of material is saved for production, and the cost is reduced by about 20 percent. Simple structure, convenience and practicality.
Description
Technical Field
The utility model relates to an automatic cutting die structure of wasting discharge of cell-phone back protection film.
Background
The three layers of materials commonly used for producing the mobile phone back protective film at present are a single-sided adhesive tape, a release film and an OPP waste discharge film; firstly, because the product is large, the OPP waste discharge film occupies a large part of the whole cost, so a better method is needed to save the OPP waste discharge film and reduce the cost; as shown in fig. 1, in the existing machining process, after punching, frame waste needs to be discharged by pulling up, hole waste needs to be discharged by pulling down, waste is discharged twice in total, the utilization rate of a machine table is occupied, and the production efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model discloses shortcoming to prior art exists provides an automatic cutting die structure of wasting discharge of cell-phone back protection film, has reduced the waste discharge step, has improved production efficiency, the while also the cost is reduced.
Therefore, the utility model adopts the following technical proposal: the utility model provides an automatic cutting die structure of wasting discharge of cell-phone back protection film, its characterized in that is including the last cutting die and the tool board down of mutually supporting, last cutting die on set up the sword frontal area, one side in sword frontal area sets up the waste material kicking block, the height of waste material kicking block is higher than the height in sword frontal area, the tool board down on open and have the blanking hole that matches with waste material kicking block size, the lower part in blanking hole is that the blanking is regional.
The height in sword sharp district be 4mm, the height of waste material kicking block be 6mm, the thickness of the lower tool plate that is located the blanking district is 2 mm.
The upper cutting die is provided with sleeve position needles at four corners, and the lower jig plate is provided with sleeve position holes matched with the sleeve position needles.
The waste material kicking block be two, one big one little and interval setting.
The distance between the blade and the ejector block is the jumping distance of a product on the die cutting machine.
The utility model can directly eject the waste to the blanking area by utilizing the waste ejecting block on the upper cutting die; the waste discharge step is reduced, and the production efficiency is improved; because the waste can be directly pushed downwards, a layer of material is saved for production, and the cost is reduced by about 20 percent. Simple structure, convenience and practicality.
Drawings

Fig. 2 is a schematic view of the upper cutting die structure of the present invention.
Fig. 3 is a schematic diagram of the lower jig plate structure of the present invention.
Detailed Description
The following describes a concentric dual-axis control mechanism according to the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 2-3, the utility model discloses an automatic cutting die structure of wasting discharge of cell-phone back protection film, including last cutting die 1 and lower tool plate 5 of mutually supporting, set up blade edge district 3 on going up the cutting die, one side in blade edge district sets up waste material kicking block 2, the height of waste material kicking block is higher than the height in blade edge district, it has the blanking hole 7 that matches with waste material kicking block size to open on the tool plate down, the lower part in blanking hole is blanking region 8.
The height in sword sharp district is 4mm, and the height of waste material kicking block is 6mm, and the thickness of the lower tool plate that is located the blanking district is 2 mm. The upper cutting die is provided with sleeve position needles 4 at four corners, and the lower jig plate is provided with sleeve position holes 6 matched with the sleeve position needles. The waste material kicking block is two, and one is big one little and the interval sets up. The distance between the blade point and the top block is the jumping distance (79mm) of a product on the die cutting machine.
The production method comprises the following steps:
1. in order to ensure the matching accuracy of the upper cutting die and the lower jig, the upper cutting die and the lower jig are formed by combining the sleeve position needle and the sleeve position hole;
2. the distance between the blade and the top block is a jump (79MM) of the product, and the jump is arranged on the die cutting machine;
3. when the die-cutting machine performs downward die cutting, the waste is dragged to a blanking hole by using a material dragging of the die-cutting machine, and the waste is pushed to a blanking area by using a waste pushing block; the method reduces the waste discharge step and improves the production efficiency; because the waste can be directly pushed downwards, a layer of material is saved for production, and the cost is reduced by about 20 percent.
The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
