[Specific implementation method] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] Example 1: Please refer to Figure 1-17A mold closing and resetting auxiliary device comprises a locking mechanism 3 arranged on the second template B for locking the first template A and the second template B, and a slider telescopic mechanism 2 arranged on the first template A and cooperating with the locking mechanism 3 to lock the first template A and the second template B. One side of the slider telescopic mechanism 2 is provided with an unlocking mechanism 1 for unlocking the first template A and the second template B after being locked. The first template A and the second template B are locked by the locking mechanism 3 and the slider telescopic mechanism 2 so that the front mold slide position C on the first template A is reset to its position, the front mold slide position is reset, and the first template A is locked by the locking mechanism and the slider telescopic mechanism. The first template and the second template enable the front mold slide on the first template to be reset into place, preventing the hard plastic front mold slide from being crushed and ensuring product quality. The unlocking mechanism can release the lock of the first template and the second template to facilitate the next mold closing process to complete the product. The locking mechanism and the slider telescopic mechanism can release or re-establish the connection at the position where the front mold slide is correctly reset, ensuring that the first template accurately reaches the predetermined position. The locking mechanism ensures the stability of the mold in the closed state, ensures that the front mold slide is reset in place, and avoids product defects caused by the failure to reset the front mold slide, such as surface scratches, unevenness, and product surface deformation.

[0035] In this embodiment, a protruding closing opening H is provided at the bottom of the front mold slide C, and the upper part of the closing opening is the product injection molding part D. The closing opening H partially wraps the product. When the front mold slide C is fully reset, the closing opening H is at the bottom of the product, and the front mold slide C does not cause damage to the product. When the first template A is not molded into place, there is a gap with the second template B. The inclined block on the first template A provides a horizontal component of force to push the front mold slide C closer to the product. Since the first template A is not molded into place, the protruding part of the closing opening H is not reset to the bottom of the product, but collides with the side corners of the product, thereby causing crushing to the hard rubber after the first injection molding.

[0036] Further, as a preferred implementation of the present solution but not limiting, the locking mechanism 3 includes a locking portion 32 for engaging with the slider telescopic mechanism 2 and an inserting portion 31 for the unlocking mechanism 1 to extend into the locking mechanism 3 .

[0037] Furthermore, as a preferred embodiment of the present invention but not a limitation, the engaging portion 32 includes a fifth straight surface 35 for locking with the slider telescopic mechanism 2, and a sixth inclined surface 37 for retracting the slider telescopic mechanism 2 into the first template A is provided on one side of the fifth straight surface 35, and a fifth inclined surface 36 is provided on the side away from the fifth straight surface 35. The extending portion 31 is a third groove for accommodating the unlocking mechanism 1, and the fifth straight surface 35 is used to abut against the first slider 211 after the first template A is pushed into place so that the first template A is locked with the second template B and the front mold position in the first template A is reset.

[0038] Furthermore, as a preferred embodiment of the present invention but not a limitation, the slider telescopic mechanism 2 includes a first slider telescopic mechanism 21 and a second slider telescopic mechanism 22 which are arranged on the first template A and can extend and retract into the first template A. The first slider telescopic mechanism 21 includes a first slider 211 and a first spring 212, and the second slider telescopic mechanism 22 includes a second slider 221 and a second spring 222. The first spring 212 and the second spring 222 can provide a reverse elastic force. When the external force disappears, the spring will push the first slider 211 and the second slider 221 back to the initial position, thereby realizing the function of automatic reset.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first slider 211 is provided with an end face for abutting against the unlocking mechanism 1 which is a second straight face 2111, the other end face of the first slider 211 is a second inclined face 2112, the second slider 221 is provided with an end face for abutting against the unlocking mechanism 1 which is a third straight face 2211, and the other end face of the second slider 221 is a third inclined face 2212.

[0040] Furthermore, as a preferred embodiment of the present invention but not a limitation, the unlocking mechanism 1 is provided with a first groove 111 for abutting against the slider telescopic mechanism 2 and a second groove 112 for accommodating the slider telescopic mechanism 2, the first groove 111 is provided with a first straight surface 1111 for abutting against the first slider telescopic mechanism 21 and the first slider telescopic mechanism 21, the second groove 112 has a first inclined surface 1121 on the side close to the first groove 111 and a first curved surface 1122 on the side away from the first groove 111.

[0041] Embodiment 2: This embodiment provides a mold, including a mold resetting auxiliary device as described in the above embodiment, wherein the unlocking mechanism 1 is installed on a first sprue plate 1001, a second sprue plate 1002 is provided on one side of the first sprue plate 1001, a panel 1003 is provided on the second sprue plate 1002, and the other side of the first sprue plate 1001 is a first template A.

[0042] Further, as a preferred implementation of the present solution but not a limitation, the locking mechanism 3 is installed on the second template B, and a square iron 3001 is provided on one side of the second template B, and a bottom plate 3002 is provided on one side of the square iron.

[0043] The working principle of this embodiment is as follows: A mold closing and resetting auxiliary device, in which the movement process is as follows: first, the unlocking mechanism 1 installed on the first sprue plate moves together with the first sprue plate, and the first straight surface 1111 on the unlocking mechanism 1 abuts against the second straight surface 2111 on the first slider, because the first slider is connected to the first template A, and then the first template A moves toward the second template B together with the unlocking mechanism 1. Because the first slider 211 has a second inclined surface 2112, and the second slider 221 has a third inclined surface 2212, when moving toward the second template B, the sixth inclined surface 37 on the locking mechanism 3 contacts the third inclined surface 2212, and the second slider 221 is retracted into the first template A, and the first template A continues to move toward the second template B together with the pushing mechanism 1, and the sixth inclined surface 37 on the locking mechanism 3 contacts the unlocking mechanism 1, and the first slider 211 is retracted into the first template A. At this time, the second straight surface 1111 on the first slider 211 2111 is separated from the first straight surface 1111 on the unlocking mechanism 1, and the unlocking mechanism 1 moves toward the second template B. Because the second slider 221 pops out of the first template A due to the action of the second spring, the first straight surface 1111 on the unlocking mechanism 1 abuts against the third straight surface 2211 on the second slider 221, and the first template A continues to move toward the second template B together with the unlocking mechanism 1. The third inclined surface 2212 on the second slider 221 moves toward the second template B, and then the third inclined surface 2212 contacts the fifth inclined surface 36. The second slider 221 is retracted toward the first template A by the horizontal component force. When the third straight surface 2211 on the second slider 221 is about to separate from the first straight surface 1111 on the unlocking mechanism 1, the first template A is pushed into place. If it is not pushed into place, the third straight surface 2211 on the second slider 221 is not separated from the first straight surface 1111 on the unlocking mechanism 1.

[0044] This design ensures that the first template A is pushed into place, the second slider 221 is retracted into the first template A, the push rod 11 continues to move until the first gate plate is connected to the first template A, and the fifth straight surface 35 is connected to the second straight surface 2111. When the front mold is reset, the connection between the first template A and the second template B is locked to make the front mold reset more accurate. When the first template A is separated from the second template B, the unlocking mechanism 1 moves between the first slider 211 and the second slider 221 so that the first slider 211 and the second slider 221 are retracted into the first template A to ensure that the first template A and the second template B can be separated normally.

[0045] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or a number of technical deductions or replacements based on the concept of the present application, should be considered as the protection scope of this application.
