[0050] The first module 1 and the second module 2, the second module 2 is arranged on the mold closing device, the first module 1 is connected with the moving part on the mold closing device, in the utility model, the second module 2 is in static state, the first module 1 acts according to the moving part, under the action of mold closing device, make the first module 1 move to the position of second module 2 and realize mold closing, in the utility model mold closing device adopts prior art, the utility model does not further limit again, but it needs to be explained that the guide rod is arranged on the first module 1, the guide hole is arranged on the second module 2, when mold closing, the guide rod is inserted into the guide hole, ensure the stability when the first module 1 and the second module 2 move.

[0051] As shown in Figure 3 The installation groove 3 is formed in the second module 2, and a plurality of discharge channels 4 are arranged along the outer edge of the installation groove 3; in the use stage, the circular valve body 8 is placed in the installation groove 3; before use, the first module 1 and the second module 2 are in a separated state, and the circular valve body 8 is placed in the installation groove 3; under the action of the mold closing device, the first module 1 moves to the position of the second module 2;

[0052] The drive positioning rod 5 passes through the first module 1 and can move within the first module 1. One end of the drive positioning rod 5 is provided with several sliding grooves 6, and the distance between the end of the several sliding grooves 6 away from the first module 1 and the axis is less than the distance between the end of the adjacent first module 1 and the axis. Several side-cutting devices 7 are all disposed on the first module 1 and are positioned opposite to several discharge channels 4. One end of each side-cutting device 7 passes through several sliding grooves 6. When the mold closing device moves with the drive positioning rod 5, one end of the drive positioning rod 5 is inserted into the circular valve body 8. At this time, several side-cutting devices 7 are positioned at one end of the drive positioning rod 5, and a portion of each side-cutting device 7 is placed inside the circular valve body 8. At this time, the first module 1 is in contact with the second module 2, and the mold closing device continues to operate, which will drive several side-cutting devices 7 to slide in several grooves 6, and make several side-cutting devices 7 gradually move away from the axis of the drive positioning rod 5; at the same time, during the operation of the side-cutting devices 7, they will contact the side wall of the circular valve body 8. Since the mold closing device continuously applies clamping force, it can make several side-cutting devices 7 side-cut the side wall of the circular valve body 8 during the movement; after the side-cutting is completed, the cut-off part on the circular valve body 8 will enter several discharge channels 4 and be discharged from the second module 2; opening the first module 1 and replacing the circular valve body 8, and repeating the operation in a cycle, can achieve side-cutting of different circular valve bodies 8.

[0053] like Figures 1-5 As shown, the first module 1 includes a first base plate 11 and a first fixing plate 12, with the first fixing plate 12 disposed on the first base plate 11; a pressure plate 13 is disposed on the first fixing plate 12 via several limiting rods; a drive positioning rod 5 passes through the pressure plate 13 and is connected to a mold handle 14 passing through the pressure plate 13; specifically, the mold handle 14 is connected to the mold closing device and to the drive positioning rod 5; the first base 11 is disposed on the mold closing device, a guide post is mounted on the first fixing plate 12, and a spring is also sleeved on the guide post, with the spring positioned between the first fixing plate 12 and the pressure plate 13, thereby... During the mold closing process, the pressure plate 13 can be buffered from the force. On the other hand, after the mold is opened, the pressure plate 13 can be separated from the first fixed plate 12. When the mold is closed, the pressure plate 13 contacts the second module 2. Since there is a space between the pressure plate 13 and the first fixed plate 12, the drive positioning rod 5 will continue to move into the circular valve body 8 under the drive of the mold closing device. Since the pressure plate 13 is released from the second module 2, the pressure plate 13 cannot continue to move. The several side cutting devices 7 set on the pressure plate 13 will slide away from the drive positioning rod 5 along several sliding grooves 6 to achieve side cutting of the circular valve body 8.

[0054] like Figures 4-5 As shown, several side-cutting devices 7 are all mounted on the pressure plate 13, and the pressure plate 13 is provided with several movement spaces 15; the several side-cutting devices 7 are respectively arranged within the several movement spaces 15; ensuring that the side-cutting devices 7 have sufficient movement distance when the mold is closed; asFigures 8-15 As shown in the drawings, the side cutting device 7 comprises a sliding block 71, a cutting block 72 and a cutting knife 73, the sliding block 71 is arranged in the action space 15, and there is a distance between the sliding block 71 and one end of the action space 15; the cutting block 72 is movably arranged on the sliding block 71; the cutting knife 73 is arranged on the cutting block 72 and simultaneously acts with the cutting block 72; specifically, the sliding block 71 is embedded in the pressing plate 13, and the cutting block 72 is placed in the action space 15, in the utility model, preferably, the sliding block 71 is connected with the pressing plate 13 through bolts, which facilitates the disassembly and assembly of the sliding block 71; the cutting block 72 is clamped in the sliding block 71 through the sliding block 71, and the cross section of the cutting block 72 is T-shaped, thereby ensuring that the cutting block 72 will not be separated from the sliding block 71 after being installed through the sliding block 71; one end of the cutting block 72 is provided with a mounting groove 3, and the cutting knife 73 is arranged in the mounting groove 3; of course, in order to ensure the stability of the cutting knife 73 and replace the cutting knife 73 according to different circular valve bodies 8, a limiting block 74 is further arranged in the utility model, the limiting block 74 passes through the positioning hole on one side of the cutting block 72, the cutting knife 73 and the positioning hole on the other side of the cutting block 72 in sequence, and then fixes the cutting knife 73 on the cutting block 72; in this way, the fixing between the cutting knife 73 and the cutting block 72 can be realized through the limiting block 74, so as to avoid the separation of the cutting knife 73 from the cutting block 72 during the action; when the cutting knife 73 is disassembled, the limiting block 74 is taken out, and the cutting knife 73 is directly slid into or out of the mounting groove 3 of the cutting block 72, thereby completing the installation or disassembly of the cutting knife 73.

[0055] It should be noted that one end of the cutting block 72 is arranged obliquely, so as to be matched with the driving positioning rod 5, thereby realizing that the cutting knife 73 can act away from the axis of the driving positioning rod 5 during the action stage, and realizing the side cutting of the circular valve body 8; in addition, the size of the cutting block 72 can be changed according to needs, so that it can move in a larger range in the action space, thereby realizing the side cutting of the circular valve body 8 with a thicker side wall.

[0056] As shown in the drawings, Figure 6 and 7 the second module 2 comprises a second bottom plate 21 and a second fixed plate 22 arranged on the second bottom plate 21; the mounting groove 3 and the plurality of discharge channels 4 are arranged on the second fixed plate 22; the second bottom plate 21 is connected with the mold closing device; as shown in the drawings, Figure 7 the distance between one end of the plurality of discharge channels 4 adjacent to the mounting groove 3 and the second bottom plate 21 is greater than the distance between the other end of the plurality of discharge channels 4 away from the mounting groove 3 and the second bottom plate 21; that is, in the utility model, the plurality of discharge channels 4 are arranged obliquely on the second fixed plate 22, and after the side cutting of the circular valve body 8 is completed, the cut part will enter the plurality of discharge channels 4, and since the discharge channels 4 are arranged obliquely, the cut part will slide out of the second fixed plate 22 along the discharge channels 4, without the need for manual cleaning; in addition, in the utility model, the opening of the other end of the discharge channels 4 away from the mounting groove 3 gradually increases, so as to avoid the blockage of the discharge channels 4 by the cut part.

[0057] In addition, in order to ensure the stability of the circular valve body 8 during the clamping or side cutting process, the bottom of the installation groove 3 is provided with a positioning block 23, and the positioning block 23 is matched with the positioning groove 81 at the bottom of the circular valve body 8. Then, the position of the circular valve body 8 can be limited by the positioning block 23 during the clamping and side cutting process, so as to avoid the movement of the circular valve body 8. As shown in the drawings, the positioning groove 81 at the bottom of the circular valve body 8 includes two through parts, which are a circular groove and a rectangular groove in communication, and the positioning block 23 corresponding to the positioning groove 81 is provided with an integral circular protrusion and a rectangular protrusion. When the circular valve body 8 is placed in the installation groove 3, the positioning groove 81 is clamped with the positioning block 23, so as to avoid the rotation of the circular valve body 8. Figure 16

[0058] As shown in the drawings, after clamping, the pressing plate 13 will be in contact with the second fixed plate 22, and the circular valve body 8 will be pressed into the installation groove 3 through the pressing plate 13. In order to improve the effect of side cutting, the circular valve body 8 needs to be always in close contact with the pressing plate 13 in the clamped state. Therefore, in the utility model, a spring groove 24 is formed in the second bottom plate 21, and an elastic element 25 is arranged between the positioning block 23 and the spring groove 24. In this way, after clamping, the elastic element 25 is compressed, and due to the elastic deformation of the elastic element 25 itself, the circular valve body 8 is pushed into contact with the pressing plate 13. In this way, when side cutting is performed, the side wall of the circular valve body 8 can be better cut off. In the utility model, the preferred elastic element 25 is a spring. Figure 3

[0059] In the utility model, the discharge channel 4, the chute 6 and the side cutting device 7 can be arranged according to different needs, so as to meet different side cutting needs. In the utility model, preferably, the discharge channel 4 is not less than three, the chute 6 is not less than three, and the side cutting device 7 is not less than three. The number of the discharge channel 4, the chute 6 and the side cutting device 7 is equal. In this way, after the circular valve body 8 is side cut, three grooves can be side cut on the circular valve body 8. It should be noted that if the hole is opened, the cutting knife 73 needs to be replaced. If the number of side cutting is increased, the number of the discharge channel 4, the chute 6 and the side cutting device 7 needs to be increased. Of course, the number of the pressing plate 13, the second fixed plate 22 and the chute 6 on the driving positioning rod 5 needs to be changed correspondingly. The specific matching number needs to be adjusted, and the utility model does not further limit this.

[0060] ​​In summary, the technical scheme of the utility model discloses drive positioning rod 5 set up on the first module 1 and the installation groove 3 set up on the second module 2, can place the circular valve body 8 in the installation groove 3, drive positioning rod 5 drive side cutting device 7 to act in the sliding slot 6 on drive positioning rod 5, and the sidewall of circular valve body 8 is side cut in the process of action, and because the utility model discloses a plurality of sliding slots 6 and a plurality of side cutting devices 7, then a plurality of side cutting devices 7 can act in a plurality of sliding slots 6 simultaneously under the drive of drive positioning rod 5, and circular valve body 8 is side cut simultaneously in the process of action, compared with prior art, without side cutting circular valve body 8 one by one, can complete the forming of a plurality of grooves or holes simultaneously, improve the overall efficiency, ensure the uniformity and accuracy of grooving or hole opening, and then can reduce the equipment volume and reduce the scrap rate.
