Description

Die positioning structure

This creation is related to a knife mold, especially a knife mold positioning structure.

Press, after the general plastic blister is formed, there will be several finished products, which need to be cut by a die. The die will be designed according to the style of the forming die, generally made of metal. When the blister is formed, it passes through the knives. The cutting edge of the die surface performs the cutting action, so that the plastic blister can be separated into a single individual.

However, this die, because it is formed by metal processing, requires a long time and cost, not only requires considerable cost in replacement, but also the position of the blade is fixed, plastic vacuum forming and hollow forming blister There will be different shrinkage during molding. If the cutting is performed with a fixed cutting edge, the finished product will have different boundaries, resulting in insufficient precision of the finished product.

The present invention is a die positioning structure, a body, the system is composed of a plate, the body is provided with a screw hole at a predetermined position, at least one die, the die is a body, and the top surface of the block is At least one blade is fixed, the block is provided with at least one pivot groove, and a plurality of connecting grooves are formed on the upper of the pivot grooves, and the connecting groove and the pivot groove are penetrated through the block, and the block is opposite to each other. A positioning block is formed on the inner side of the blade, a pivoting rod is provided on one side of the pivoting rod for screwing into the screw hole, and a pivoting portion 32 is formed in the middle of the pivoting rod to be sleeved in the pivot slot. its The pivoting portion is longer than the pivoting groove and has a smaller diameter than the pivoting groove, and the pivoting bar is provided with a stop block which is larger than the diameter of the pivoting groove and located in the connecting groove.

The utility model provides a die positioning structure. When the pivoting bar connects the knife module to the body, the die can generate a swing and can be positioned through the upper positioning block and the object to be cut, and can be adjusted during positioning. The position of the blade can increase the accuracy of the cutting.

Figure 1 is an exploded perspective view of a preferred embodiment of the present invention.

Figure 2 is a partial cross-sectional view of the preferred embodiment of the present invention.

Figure 3 is a partial cross-sectional view of the preferred embodiment of the present invention.

Please refer to FIGS. 1 and 2 , which are an exploded perspective view and a partial cross-sectional view of a tool mold positioning structure, which includes a body 10 which is formed by a plate body. The utility model is provided with a screw hole 11; nine die cutters 20, wherein the die cutters 20 are a single body 21, and the block body 21 is formed by stacking two wooden boards 211, and a plurality of wood boards can be stacked according to requirements. A metal plate 212 is interposed between the boards 211. The top surface of the block 21 is fixed with a ring-shaped blade 22, and the end of the blade 22 is abutted against the metal plate 212. The metal plate is disposed downwardly with two pivoting grooves 23, and a plurality of connecting grooves 24 are formed above the pivoting grooves 23. The connecting groove 24 and the pivoting groove 23 are penetrated through the block 21, and the block 21 is opposite to the blade. A positioning plate 25 is formed on the inner side of the positioning plate 25, and a positioning block 26 is formed between the positioning plate 25, and a connecting groove 261 is disposed in the center of the positioning block 26, and the positioning block 26 is simultaneously disposed. The top of the top is provided with a tapered cone portion 262; A pivoting rod 30 is provided with a thread 31 on one side of the pivoting rod 30 for screwing into the threaded hole 11. A pivoting portion 32 is formed in the middle of the pivoting rod to be sleeved in the pivoting slot 23, and is pivotally connected thereto. The portion 32 is longer than the pivot slot 23 and has a smaller diameter than the pivot slot 23, and the pivot rod 3 is provided with a stop block 33 which is larger than the diameter of the pivot slot 23 and located in the connecting slot 24.

In order to further understand the characteristics of this creation, the use of the means of technology and the expected results, the use of this creation is described, I believe that this can be a deeper and more specific understanding of this creation, as described below; 2, when the die 20 is to be cut, the body 10 is moved, so that the die 20 can be moved to the cutting position. At this time, the die 20 is dropped by its own gravity, and the block 33 will It is located on the metal plate 212, and when it is in contact with the object to be cut, it is first contacted by the positioning block 26, and when the positioning block 26 is in contact with the object to be cut, because of the gap between the pivot rod 30 and the pivot groove 23, the knife The mold 20 can generate a slight swing to adjust the position. When the positioning block 26 is completely in contact with the object to be cut, it can be known that the die 20 has been positioned. Thus, the blades 22 of the different die 20 on the body 10 can be self-contained. Adjustment has a more accurate cutting, which can improve the precision of processing and ensure the quality.

In addition, it is worth mentioning that because the die 20 is combined with the body 10 instead of being integrally formed, partial replacement or repair is required, and only part of it needs to be adjusted, which can reduce the cost and time of repair and replacement, and The body 10 and the block body 21 are processed by using wood, and the processing time is relatively fast, the replacement period is short, and the user's demand can be quickly completed. Moreover, the inclined taper portion 262 can generate a large accommodation space during positioning. To avoid injury to the object to be cut and to be easily positioned.

Please refer to FIG. 3 again, which is a partial cross-sectional view of a preferred embodiment of the present invention. The main structure is the same as that of the previous embodiment, and therefore will not be described again, wherein the pivot slot 23 is close to the present embodiment. The body 10 is recessed with a receiving groove 27, and an elastic member 28 is disposed in the receiving groove 27. When the die 20 is disposed under the object to be cut, the elastic member 28 generates an elastic force to be applied to the die 20 Push, so that it can still produce a positioning effect when used below

The above examples of the present invention are for illustrative purposes only and should not limit the meaning of the creation, that is, the various changes that can be made within the scope of the listed patents, and should be included in the application of the case. In the scope of patents.
