Utility Model Content

[0004] The purpose of the present invention is to provide a screw mold that is easy to position, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a screw mold that is easy to position, comprising a base and a column, wherein a control portion for maintaining the stability of the screw axis is provided on the inner side of the base, and the control portion comprises:

[0007] Preferably, an insert rod is fixedly connected to the inner side of the positioning plate, and when the positioning plate moves downward, it will drive the sliding rod and the inclined column to move downward together, and when the inclined column moves downward, it will conflict with the ratchet bar, so that the inclined column pushes the sliding rod, and the sliding rod will not only compress the spring 2, but also the insert rod will be inserted into the inclined column. The insert rod passes through the sliding rod and is slidably connected, and the insert rod also passes through the inclined column and is slidably connected.

[0008] Preferably, a second spring is fixedly connected to the inner side of the positioning plate, and one end of the second spring close to the slide rod is fixedly connected to the surface of the slide rod.

[0009] Preferably, a ratchet bar is hinged on the inner side of the column, and the ratchet bar will be tightened under the interference of the torsion spring, and at the same time, the interference block located in the groove will interfere, so that the bottom end of the ratchet bar is supported by the I-shaped slider and the connecting rod and cannot rotate, so that the positioning plate will cause the inclined column to interfere with the inclined ratchet bar when pressed down, thereby forcing the inclined column to continuously push the slide rod and drive the positioning piece to fix the screw head, and a torsion spring is fixedly connected between the ratchet bar and the inner side of the column.

[0010] Preferably, an I-shaped slider passes through the bottom end of the ratchet bar, and a connecting rod is fixedly connected to the surface of the I-shaped slider.

[0014] 1. The screw mold is easy to position. The ratchet bar will be tightened under the resistance of the torsion spring, and the resistance block located in the groove will resist at the same time, so that the bottom end of the ratchet bar is resisted by the I-shaped slider and the connecting rod and cannot rotate. When the positioning plate is pressed down, the inclined column will resist the inclined ratchet bar, thereby forcing the inclined column to continuously push the slide bar to drive the positioning piece to fix the screw head, or some thinner screw heads are pressed between the positioning piece and the inner side of the positioning plate, thereby tightening the screw head. In addition, the axis of the screw can be kept consistent and fixed in the positioning plate through the arrangement of six groups of circular arrays, so as to avoid the deviation of the screw due to vibration when the screw is headed, resulting in the tilting of the heading groove.

[0015] 2. This screw mold is easy to position. After the heading is completed, the rotating ring is rotated so that the inclined surface of the groove is inserted into the inner side of the interference block, forcing the interference block to pull the I-shaped slider through the connecting rod, so that the I-shaped slider pulls the ratchet bar, and then the ratchet bar no longer conflicts with the inclined surface column, and the compressed spring pushes the slide to move upward, so that the positioning disk is reset and raised and no longer positions the screw. The operation is simple, the positioning can be done when heading, and it is released after rising, thereby improving the efficiency of screw heading. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a screw mold that is easy to position, including a base 1 and a column 3. The inner side of the base 1 is provided with a control part 2 for maintaining the stability of the screw axis. The control part 2 includes:

[0023] The slide 21 passes through the column 3 and is slidably connected. The end of the slide 21 away from the column 3 is fixedly connected to the positioning plate 22. The bottom surface of the slide 21 is fixedly connected to a spring 23. The end of the spring 23 away from the slide 21 is fixedly connected to the inner side of the column 3. The inner side of the positioning plate 22 passes through and is slidably connected to a slide rod 24. When the mold is processing the screw head, the screw is aligned with the middle of the three groups of columns 3, and the bottom end of the screw is inserted into the positioning plate 22 and presses the screw head downward, so that the screw moves downward against the positioning plate 22. When the positioning plate 22 moves downward, it will drive the slide rod 24 and the inclined column 25 to move downward together. The surface of the slide rod 24 is fixedly connected to the inclined column 25, which passes through the positioning plate 22 and is slidably connected. The top surface of the slide rod 24 is fixedly connected to the positioning piece 217. An insert rod 26 is fixedly connected to the inner side of the positioning plate 22. When the positioning plate 22 moves downward, it also drives the slide bar 24 and the inclined column 25 downward. When the inclined column 25 moves downward, it contacts the ratchet bar 28, causing the inclined column 25 to push the slide bar 24. The slide bar 24 not only compresses the second spring 27, but also inserts the insert rod 26 into the inclined column 25. The insert rod 26 penetrates the slide bar 24 and is slidably connected. The insert rod 26 also penetrates the inclined column 25 and is slidably connected. The inner side of the positioning plate 22 is fixedly connected to the second spring 27. The end of the second spring 27 near the slide bar 24 is fixedly connected to the surface of the slide bar 24. A ratchet bar 28 is hingedly connected to the inner side of the column 3. The ratchet bar 28 is tightened by the torsion spring 29 and the abutment block 213 located in the groove 216, causing the bottom end of the ratchet bar 28 to be abutted by the I-shaped slider 210 and the connecting rod 211, preventing it from rotating. This allows the positioning plate 22 to press downward, causing the inclined post 25 to abut the inclined ratchet bar 28, forcing the inclined post 25 to continuously push the slider 24, driving the positioning piece 217 to secure the screw head. A torsion spring 29 is fixedly connected between the ratchet bar 28 and the inner side of the column 3. The bottom end of the ratchet bar 28 passes through the I-shaped slider 210, to which the surface of the I-shaped slider 210 is fixedly connected to the connecting rod 211. The connecting rod 211 passes through the column 3 and is slidably connected. The end of the connecting rod 211 away from the I-shaped slider 210 is fixedly connected to the abutment block 213. A spring 3 212 is fixedly connected between the I-shaped slider 210 and the inner side of the column 3. A connecting ring 214 is embedded in and rotatably connected to the inner side of the column 3 . A rotating ring 215 is fixedly connected to the surface of the connecting ring 214 . A groove 216 is formed on the surface of the rotating ring 215 .

[0024] Based on the above embodiment, when the mold is processing the screw head, the screw is aligned with the middle of the three groups of columns 3, and the bottom end of the screw is inserted into the positioning plate 22 to press the screw head downward, so that the screw moves downward against the positioning plate 22, and when the positioning plate 22 moves downward, the slide bar 24 and the inclined column 25 are driven to move downward together, and when the inclined column 25 moves downward, it will conflict with the ratchet bar 28, so that the inclined column 25 pushes the slide bar 24, and the slide bar 24 will not only compress the spring 27, but also the insertion rod 26 will be inserted into the inclined column 25, but the ratchet bar 28 will be tightened under the resistance of the torsion spring 29, and at the same time, it is located in the groove 216. The abutment block 213 abuts, so that the bottom end of the ratchet bar 28 is abutted by the I-shaped slider 210 and the connecting rod 211 and cannot rotate, so that the positioning plate 22 presses down and causes the inclined column 25 to abut the inclined ratchet bar 28, thereby forcing the inclined column 25 to continuously push the slide bar 24 and drive the positioning piece 217 to fix the screw head, or press some thinner screw heads between the positioning piece 217 and the inner side of the positioning plate 22, thereby tightening the screw head, and through the six groups of circular arrays, the axis of the screw can be kept consistent and fixed in the positioning plate 22, to avoid the screw from vibrating and causing the heading groove to tilt when the screw is headed.

[0025] After the heading is completed, the rotating ring 215 is rotated so that the inclined surface of the groove 216 is inserted into the inner side of the interference block 213, forcing the interference block 213 to pull the I-shaped slider 210 through the connecting rod 211, so that the I-shaped slider 210 pulls the ratchet bar 28, and then the ratchet bar 28 no longer interferes with the inclined surface column 25, and the compressed spring 1 23 pushes the slide 21 to move upward, so that the positioning plate 22 is reset and raised and no longer positions the screw. The operation is simple, it can be positioned when heading and released after rising, thereby improving the efficiency of screw heading.

[0026] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
