fig. 1 is a schematic structural view of a locking plastic screw thread die provided by the utility model.

Fig. 2 is a schematic structural view of the molding screw manufactured from fig. 1.

Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Please refer to fig. 1 and fig. 2, wherein fig. 1 is a schematic structural diagram of a screw die for locking plastic screws according to the present invention. The anti-loosening plastic screw die comprises a static plate 10 and a movable plate 20, wherein the movable plate 20 can slide on the static plate 10. The fixed plate 10 and the movable plate 20 are respectively provided with a plurality of threads 30 and a plurality of tooth sockets 40, the threads 30 and the tooth sockets 40 are positioned on the upper end surfaces of the fixed plate 10 and the movable plate 20, the tooth sockets 40 are recessed in the fixed plate 20 and the movable plate 10, the tooth sockets 40 are positioned between two adjacent threads 30, and the thread sockets 30 are flush with the upper end surfaces of the fixed plate 10 or the movable plate 20. The teeth 30 and the tooth sockets 40 are disposed obliquely to the long sides of the stationary plate 10 and the movable plate 20, and each of the stationary plate 10 and the movable plate 20 includes a first port 50 and a second port 60. It should be noted that the first port 50 and the second port 60 are respectively disposed at two ends of the stationary plate 10 or the movable plate 20, the first port 50 is used for placing a screw to be processed (not shown), and the second port 60 is used for placing a forming screw 70. The teeth 30 are provided with a plurality of anti-slip threads 35 at an end thereof adjacent to the first port 50, and the stationary plate 10 and the movable plate 20 are further provided with a plurality of forming grooves 80 at upper end surfaces thereof adjacent to the second port 60, wherein the forming grooves 80 partially intersect with the anti-slip threads 35. In this embodiment, a screw to be processed is placed in the first port 50, the screw to be processed is threaded by moving the stationary plate 10 and the movable plate 20 relatively, and a molding screw 70 is obtained at the second port 60. The forming groove 80 and the anti-slip pattern 35 are partially intersected, so that the screw to be processed can be effectively transited in the forming process, and the screw to be processed can be prevented from slipping in the forming process.

The short sides of the stationary plate 10 and the movable plate 20 have the same length, and the long side of the stationary plate 10 is smaller than the long side of the movable plate 20.

The included angle between the tooth lines 30 and the tooth grooves 40 and the long edge of the static plate 10 or the movable plate 20 is 35-45 degrees.

The forming groove 80 forms an included angle of 10-15 degrees with the short side of the static plate 10 or the movable plate 20.

The fixed plate 10 and the movable plate 20 are provided with a protruding part 90, the protruding part 90 is arranged along the long edge of the fixed plate 10 or the movable plate 20, and the forming groove 80 is arranged close to the protruding part 90. Thus, the forming screw 70 is a partial screw thread screw, which can improve the mechanical strength of the bolt and can bear larger torque. The protrusions 90 are preferably a conventional one, and include a smooth surface, a shearing surface, etc., which are well known to those skilled in the art, and thus will not be described in detail herein.

The second port 60 is provided with a forming screw 70, one end of the forming screw 70 is a screw bottom 71, the other end of the forming screw 70 is a screw tip 72, a thread section 73 is spirally wound on the forming screw 70, and the forming screw 70 is close to the screw tip 72 and is provided with a plurality of ribs 74. Since the forming groove 80 forms an included angle of 10 to 15 ° with the short side of the stationary plate 10 or the movable plate 20, it is conceivable that the rib 74 of the forming screw 70 and the length direction of the forming screw 70 are cheap, so that the forming screw 70 can be prevented from being loosened when entering wood or plastic.

Compared with the prior art, the utility model provides an anti-loosening plastic screw dental lamina mould through set up a plurality of insections 30 and alveolus 40 on quiet board 10 and movable plate 20, insection 30 and alveolus 40 slope in quiet board 10 and movable plate 20 setting, and quiet board 10 and movable plate 20 all include a first port 50 and a second port 60 that sets up forming screw 70, quiet board 10 and movable plate 20 are close to the up end of second port 60 still is equipped with a plurality of shaping grooves 80, so make forming screw 70 not only be convenient for change over to the object, also because the effect of insection 74 can be fixed with wood and plastic class article very firmly, be difficult for droing.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
