Abstract
The utility model discloses a technical field's a waste material sword structure is made to mould, including lower mould waste material sword and last mould sword piece, the edge of a knife of lower mould waste material sword is the arc structure of middle part indent, the edge of a knife of going up the mould sword piece is the arc structure of middle part evagination, and the edge of a knife of lower mould waste material sword is the same with the radian of the edge of a knife of last mould sword piece. The utility model has the advantages that: through changing traditional slash formula waste material sword into the waste material sword of arc structure, the waste material can form two contact points at the in-process waste material that is cut and lower mould waste material sword edge of a knife, has two points to support the waste material, and stability improves greatly to the problem of waste material is beated has been avoided.
Description
Technical Field
The utility model relates to a mould manufacturing technical field especially relates to a waste material sword structure.
Background
In the development process of automobile mold, the top cap waste material often can have the condition that the waste material roll-off cut off, and the oblique line formula waste material sword is adopted usually to the industry on the tradition, but this structure often can be in the middle of the process that the waste material cut off, and the waste material condition of beating appears, and the waste material stability is relatively poor in the middle of the cutting process, and the beat of waste material gets into the die cavity easily or adsorbs on the part surface, forms the indentation in follow-up moulding-die in-process, influences the part.
SUMMERY OF THE UTILITY MODEL
For overcoming the waste material problem of beating that current oblique line formula waste material sword exists, the utility model aims to solve the technical problem that: provides a scrap cutter structure capable of avoiding scrap bounce.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a waste material sword structure, includes lower mould waste material sword and goes up the mould sword piece, the edge of a knife of lower mould waste material sword is the arc structure of middle part indent, the edge of a knife of going up the mould sword piece is the arc structure of middle part evagination, and the edge of a knife of lower mould waste material sword is the same with the radian of the edge of a knife of last mould sword piece.
Furthermore, one end of the edge of the lower die waste cutter is higher than the other end of the edge of the lower die waste cutter.
Further, still include striker plate and glide rod, the striker plate is located the one end of lower mould waste material sword, the glide rod is located the other end of lower mould waste material sword.
The utility model has the advantages that: through changing traditional slash formula waste material sword into the waste material sword of arc structure, the waste material can form two contact points at the in-process waste material that is cut and lower mould waste material sword edge of a knife, has two points to support the waste material, and stability improves greatly to the problem of waste material is beated has been avoided.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of a conventional diagonal scrap knife.
Marked in the figure as 1-lower die scrap cutter, 2-upper die cutter block, 3-striker plate and 4-lower slide bar.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 2, the knife edge of the existing oblique waste knife is an oblique linear type, and during the cutting process, the waste is only supported by one point intersecting with the knife edge all the time, so that the waste has poor stability during the cutting process, and the problem of waste jumping easily occurs.
As shown in fig. 1, this application modified waste material sword structure, including lower mould waste material sword 1 and last mould sword piece 2, the edge of a knife of lower mould waste material sword 1 is the arc structure of middle part indent, the edge of a knife of going up mould sword piece 2 is the arc structure of middle part evagination, and the edge of a knife of lower mould waste material sword 1 is the same with the radian of the edge of a knife of last mould sword piece 2. Through changing lower mould waste material sword 1 into the arc structure of middle part indent, because the size of waste material is less than the waste material sword, the waste material can form the condition that two points contacted with the edge of a knife very easily when being cut in the edge of a knife of this arc structure, will have two points all the time at the in-process that continues the cutting like this to support the waste material, just the condition that the waste material is beated can no longer appear.
In order to facilitate the lower die waste material knife 1 and the upper die knife block 2 to form a shearing opening in the cutting process, the lower die waste material knife 1 is preferably set into a structural form that one end of the knife edge is higher than the other end of the knife edge, so that the shearing opening can be formed with the lower die waste material knife 1 in the vertical and downward moving process of the upper die knife block 2, and the waste materials are convenient to cut off.
Further, in order to facilitate the waste material to move to the waste material knife for cutting, a material baffle plate 3 and a lower sliding rod 4 are preferably arranged in a matched manner, the material baffle plate 3 is positioned at one end of the lower die waste material knife 1, and the lower sliding rod 4 is positioned at the other end of the lower die waste material knife 1. In the moving process of the die, the die cuts off the whole waste material for the first time, the waste material is conveyed to the lower die waste material knife 1 through the lower sliding rod 4, the front end of the waste material is abutted to the material baffle plate 3 for limiting, and the die divides the waste material into two small waste materials under the action of the lower die waste material knife 1 and the upper die knife block 2 in the next moving process.
The utility model discloses a change traditional slash formula waste material sword into the waste material sword of arc structure, the waste material can form two contact points at the in-process waste material that is cut and lower mould waste material sword edge of a knife, has two point pairs waste material to support, and stability improves greatly to avoided the waste material problem of beating, had fine practicality and application prospect.
