[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1

[0021] A wire cutting positioning device for a PET bottle cap mold valve core, such as Figure 1-Figure 4As shown, it includes: a positioning base 1, a positioning base 2 is slidably connected to the front of the positioning base 1, a protrusion 6 is fixedly connected to the surface of the positioning base 1, a number of balls 9 are slidably connected to the surface of the protrusion 6, the inside of the protrusion 6 is elastically connected to a first spring 10, the top and bottom of the first spring 10 are connected to a baffle 11, the ball 9 is rotatably connected to the inside of the baffle 11, a slide groove 4 matching the protrusion 6 is provided on the surface of the positioning base 2, the two baffles 11 are respectively installed near the top and bottom ends of the protrusion 6, and one end face of the second spring 12 is in contact with the inner wall of the protrusion 6, one end face of the protrusion 6 is fixedly connected to a spring telescopic member 14, and one end face of the spring telescopic member 14 is embedded with a number of steel balls 13.

[0022] like Figure 1 and Figure 2 As shown, a first fixing hole 7 is provided on one side of the positioning base 1 relative to the positioning base 2, and a plurality of second fixing holes 8 are equidistantly provided at one end of the positioning base 2 corresponding to the first fixing hole 7. The first fixing hole 7 and the second fixing hole 8 are fixed by a fixing component, thereby fixing the positioning base 1 and the positioning base 2, and the fixing component is one of a bolt and nut, a connecting rod and a rivet.

[0023] like Figure 1 and Figure 2 As shown, a positioning hole 3 is provided on one side of the positioning base 2 opposite to the positioning base 1 at the bottom end of the second fixing hole 8 , and the positioning hole 3 is used for connecting the positioning base 1 with other objects.

[0024] like Figure 1 and Figure 2 As shown, a channel 5 is provided at the top of the positioning base 1, which is a through groove with a preset shape having an opening. The valve core of the PET bottle cap mold is clamped in the channel 5 with a preset shape having an opening. The valve core of the PET bottle cap mold can be linearly cut through the opening of the channel 5. An inclination angle is provided on one end face of the channel 5. Since the upper surface of the positioning base 1 facing outward is an inclined surface, when the valve core of the PET bottle cap mold is clamped in the channel 5, the bottom surface of the valve core of the PET bottle cap mold is in contact with the inclined surface of the positioning base 1, that is, the bottom surface of the valve core of the PET bottle cap mold is at a certain angle to the bottom surface of the base of the linear cutting device. Therefore, when cutting a specific inclined surface of the valve core of the PET bottle cap mold, fast cutting can be achieved and the cutting accuracy is high.

[0025] Working principle: First, align the protrusion 6 of the positioning base 1 with the slide 4, then put the protrusion 6 into the slide 4, and the rotation of the ball 9 and the steel ball 13 allows the protrusion 6 to move smoothly in the slide 4;

[0026] When the protrusion 6 is placed in the slide groove 4, the positioning base 2 applies pressure to the ball 9, causing the ball 9 to move. When the ball 9 moves, it drives the baffle plate 11 to move. When the baffle plate 11 moves, it drives the first spring 10 to be compressed, so that the tension of the first spring 10 drives the baffle plate 11 to drive the ball 9 to squeeze the inside of the positioning base 2, so that the positioning base 1 and the positioning base 2 are squeezed and fixed, and then the positioning base 1 is moved to a pre-determined position, and then the bolt is inserted into the second fixing hole 8 along the first fixing hole 7, thereby completing the fixation between the positioning base 1 and the positioning base 2.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
