[0040] Specific implementation plan:

[0041] Example 1: See Figures 1-6 This utility model is a tooling mold base for a lobster tail-cutting machine, comprising:

[0042] A fixed base 1 is provided with a first slot 11 and a second slot 12 extending in the front-back direction. The first slot 11 is located above the second slot 12. The rear end of the first slot 11 is used to place the lobster buckle body a. The lobster buckle body a is provided with a ring a1 and a tail strip a2. A linkage rod 5 is slidably installed in the first slot 11 and located in front of the lobster buckle body a. The linkage rod 5 is provided with a reset component for cooperating to drive the linkage rod 5 to reset backward.

[0043] The cutter 2 is fixedly installed in the second slot 12. The rear end of the cutter 2 is provided with an opening slot 21 for corresponding placement of the tail strip a2. The upper end of the cutter 2 is provided with a strip groove 22 for the ring a1 to slide into. The opening slot 21 and the strip groove 22 are connected to each other, and a cutting position 24 is formed at the front end of the connection.

[0044] Please see Figure 3 and Figure 6 As can be seen, in this embodiment, the cutter 2 is provided with a plug hole 23, and the lower end of the fixing base 1 is provided with a shaft hole for inserting the fixing rod. The fixing rod is inserted into both the shaft hole and the plug hole 23 to fix the position of the cutter 2.

[0045] In this embodiment, the lobster tail-cutting machine includes a frame, a divider is provided on the frame, an indexing plate is provided above the divider, and multiple tooling mold seats are evenly spaced along the edge of the indexing plate.

[0046] The working principle of the tooling mold base in conjunction with the cutting of the tail strip a2 on the lobster buckle body a:

[0047] When the divider drives one of the tooling molds to rotate to the punching station (at this time, the lobster buckle body a is already placed at the rear end of the first slot 11), the divider stops rotating, and the punching mechanism presses the punch from back to front into the first slot 11, driving the lobster buckle body a and the linkage rod 5 to move forward along the first slot 11. Since the tail strip a2 on the lobster buckle body a is arranged in the opening slot 21, the cutter 2 will block the tail strip a2, thus preventing it from moving forward with the lobster buckle body a. Therefore, when the lobster buckle body a is driven to move forward, the cutter 2 will cut off the tail strip a2.

[0048] After the tail strip a2 is cut off, it falls into the waste recycling box. Then, the punch of the punching mechanism retracts backward. At this time, the reset component drives the linkage rod 5 to reset backward (the working principle of the reset component is described below), thus completing one punching action.

[0049] As a preferred embodiment of this example, please refer to Figures 1-5 As can be seen, the fixing base 1 is provided with at least one through hole 14 extending in the front-rear direction, and the reset assembly includes:

[0050] The pin 3 is fixed at one end in the through hole 14 and extends to the front of the fixed end. The front end of the pin 3 is provided with a limiting block 31.

[0051] The sliding block 4 is slidably mounted on the pin 3 and fixed to the front end of the linkage rod 5;

[0052] The first compression spring 6 is sleeved on the outside of the pin 3 and arranged between the sliding block 4 and the fixed seat 1;

[0053] The second compression spring 7 is sleeved outside the pin 3 and arranged between the limiting block 31 and the sliding block 4.

[0054] Working principle of the reset component:

[0055] Since the sliding block 4 is fixed to the front end of the linkage rod 5, when the punch presses forward against the lobster buckle body a, it will cause the linkage rod 5 and the sliding block 4 to move forward together. At this time, the first compression spring 6 is compressed and the second compression spring 7 is stretched. When the punch returns to its original position, both the first compression spring 6 and the second compression spring 7 will restore their deformation, thereby driving the linkage rod 5 and the sliding block 4 to return to their original position. Note that since the second compression spring 7 is provided between the sliding block 4 and the fixed base 1, it ensures that the position of the linkage rod 5 after its return to its original position will not affect the subsequent normal feeding of the lobster buckle body a to the rear end of the first slot 11.

[0056] Then, please see Figure 1 and Figure 2 As can be seen, in this embodiment, there are two through holes 14, which are arranged symmetrically on the fixing base 1.

[0057] Here, the pin 3 is set up to assist the linkage rod 5 and the sliding block 4 to move back and forth more stably, and to provide a place for the first compression spring 6 and the second compression spring 7 to be installed.

[0058] Please see Figure 5 As can be seen, in this embodiment, the first slot 11 and the second slot 12 are interconnected. The rear end of the fixed base 1 is also provided with a material discharge chute 13, which is connected to the opening slot 21 and is located directly below the opening slot 21.

[0059] Here, the first slot 11 and the second slot 12 are connected, which allows the linkage rod 5 and the cutter 2 to abut against each other, thereby ensuring that the cutting surface of the cutter 2 on the lobster buckle body a is sufficiently flat.

[0060] Please see Figures 1-3 As can be seen, in this embodiment, the longitudinal cross-sectional profile of the linkage rod 5 is consistent with the longitudinal cross-sectional profile of the lobster buckle body a after the tail strip a2 is cut off. This ensures that during the punching process of the lobster buckle body a, all positions of the lobster buckle body a are in contact with the end of the linkage rod 5, resulting in more even force distribution.

[0061] In addition, please see Figure 3 and Figure 6 As can be seen, in this embodiment, the lower end of the linkage rod 5 is provided with a round rod portion 51, which is slidably disposed in the strip groove 22, and the rear end of the round rod portion 51 abuts against the ring a 1.

[0062] More specifically, the round rod portion 51 is hollow tubular, and the tooling mold base also includes a positioning component 8, which includes:

[0063] Support 81;

[0064] Connecting block 82 is fixed on support 81;

[0065] The positioning rod 83 is fixed on the connecting block 82 and passes through the round rod portion 51. The rear end of the positioning rod 83 extends behind the round rod portion 51 and is used for the ring a1 to be fitted.

[0066] The working principle of the positioning component 8: The support 81 is fixedly installed on the indexing plate, and the connecting block 82 is fixed on the support 81, thereby fixing the position of one end of the positioning rod 83. Since the positioning rod 83 passes through the round rod part 51, when the linkage rod 5 moves back and forth, the positioning rod 83 can further position the linkage rod 5, preventing it from shifting left or right during the back and forth translation process. Furthermore, since the rear end of the positioning rod 83 extends to the rear of the round rod part 51, it can also ensure that the subsequent lobster buckle body a can be smoothly positioned and fed into the first slot 11.

[0067] Example 2: Please refer to Figures 7-9 As can be seen, unlike Embodiment 1, in this embodiment, the structural design of the positioning component 8 is cancelled, and the strip groove 22 at the upper end of the cutter 2 is designed to fully accommodate the round rod 51, thereby positioning the round rod 51 with the strip groove 22, which can achieve a positioning effect similar to that of the positioning component 8 in Embodiment 1.

[0068] The above description of the tooling mold base for a lobster tail-cutting machine is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
