[0003] In related technologies, with the development of automation technology, higher requirements have been placed on the automation and precise control of molds. Although the existing front mold core-pulling mechanism can meet basic production needs, its unlocking function is poor during the core-pulling process, which can easily damage the mold. Utility Model Content
[0004] In view of this, the present invention provides a front mold core-pulling protection mechanism to solve the problems existing in the prior art.
[0005] On one hand, this utility model provides a front mold core-pulling protection mechanism. The front mold core-pulling mechanism has a core-pulling seat and includes: a slider disposed on the core-pulling seat and connected to a linear drive mechanism; a limiting block; and an elastic block engaged with a buckle. The linear drive mechanism drives the core-pulling seat to move linearly in a first direction, causing the core-pulling seat to abut against the limiting block, and the slider to abut against the elastic block, causing the elastic block to disengage from the buckle.
[0006] In one optional embodiment, the slider moves linearly along the first direction with one end facing the first direction as the trigger end. The trigger end has a first inclined surface, and the top of the elastic block has a second inclined surface. The second inclined surface is adapted to the first inclined surface, so that the slider can press the elastic block to move along the second direction and disengage from the latch. The second direction is different from the first direction.

[0010] In one optional embodiment, the side of the first trigger block facing the second trigger block is a guide slope, the second trigger block is an elastic block structure, the second trigger block has a slot, and the guide slope is inserted into the slot so that the second trigger block can move along the guide slope to disengage from the latch.
[0011] In one optional embodiment, the elastic block further includes a guide shaft extending upward from the third party, the trigger block being sleeved on the guide shaft and movable along the guide shaft, the first trigger block having a stepped hole, the elastic element being provided in the stepped hole, the elastic element being a spring, the spring being sleeved on the guide shaft and abutting against the bottom wall of the stepped hole.
[0012] On the other hand, this utility model also provides a mold, including: a front mold with a front mold core pull; a rear mold; a buckle disposed on the rear mold; and a front mold core pull protection mechanism as described in any one of the above, wherein the elastic block of the front mold core pull protection mechanism locks the buckle to lock the front mold and the rear mold, or the elastic block disengages from the buckle to unlock.
[0013] The beneficial effects of this utility model are as follows: the front mold core pulling protection mechanism automatically controls the movement of the core pulling seat through the linear drive mechanism, which can realize automated core pulling operation.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0023] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.
[0024] like Figure 1 and Figure 2As shown, according to an embodiment of the utility model, a front mold core-pulling 200 protection mechanism is provided. The front mold core-pulling 200 has a core-pulling seat 300. The front mold core-pulling 200 protection mechanism includes: a slider 110 disposed on the core-pulling seat 300 and connected to a linear drive mechanism 400; a limiting block 120; and an elastic block engaged with a buckle 500. The linear drive mechanism 400 drives the core-pulling seat 300 to move linearly along a first direction X, causing the core-pulling seat 300 to abut against the limiting block 120, and the slider 110 to abut against the elastic block, causing the elastic block to disengage from the buckle 500.
[0025] In this embodiment, the front mold core-pulling protection mechanism 200 mainly includes a slider 110, a limiting block 120, an elastic block, and a linear drive mechanism 400, which can be a hydraulic cylinder. The limiting block 120 restricts the movement range of the core-pulling seat 300, preventing it from exceeding the predetermined movement trajectory, thereby avoiding possible mechanical failures or damage. During the movement of the core-pulling seat 300, the limiting block 120 closely cooperates with the core-pulling seat 300 to ensure smooth and safe movement.
[0026] The elastic block engages with the latch 500, forming a detachable connection. Its function is to provide the necessary elastic force during the core-pulling process, ensuring that the slider 110 can smoothly separate from the product. When the core-pulling seat 300 moves linearly along the first direction X, the connection between the elastic block and the latch 500 is subjected to force, causing the elastic block to disengage from the latch 500. This disengagement is achieved by the linear drive mechanism 400 driving the core-pulling seat 300. When the core-pulling seat 300 abuts against the limit block 120, the slider 110 also abuts against the elastic block, thereby causing the elastic block to disengage from the latch 500, completing the core-pulling action.
[0027] During mold opening, the linear drive mechanism 400 drives the core-pulling seat 300 to move linearly along the first direction X. As the core-pulling seat 300 moves, the slider 110 also moves, contacting the lateral portion of the product and initiating core pulling. When the core-pulling seat 300 abuts against the limiting block 120, the slider 110 continues to move, abutting against the elastic block, causing the elastic block to disengage from the latch 500. This action allows the slider 110 to continue pulling out the lateral portion of the product, completing the core-pulling action. The front mold core-pulling 200 protection mechanism, through the coordinated work of components such as the slider 110, limiting block 120, and elastic block, ensures the smooth completion of the linear movement of the core-pulling seat 300 and the core-pulling action. This mechanism design not only improves the service life of the mold but also enhances the stability and safety of the production process, which is of great significance for improving production efficiency and product quality.
[0028] Furthermore, the slider 110 moves linearly along the first direction X with one end facing the first direction X as the trigger end. The trigger end is provided with a first inclined surface 111, and the top of the elastic block has a second inclined surface 1301. The second inclined surface 1301 is adapted to the first inclined surface 111, so that the slider 110 can press the elastic block to move along the second direction Y and disengage from the latch 500. The second direction Y is different from the first direction X.
[0029] The first inclined surface 111 is inclined in a direction away from the first direction X. The angle and shape of the first inclined surface 111 are designed to be compatible with the second inclined surface 1301 of the elastic block, so as to ensure that the slider 110 can effectively push the elastic block.
[0030] During the mold opening process, the slider 110 moves linearly along the first direction X. When the trigger end of the slider 110 contacts the elastic block, the first inclined surface 111 interacts with the second inclined surface 1301. This interaction causes the elastic block to be compressed, which helps the elastic block to smoothly disengage from the snap-fit 500.
[0031] Furthermore, the second direction Y is opposite to the first direction X. Because the second direction Y is opposite to the first direction X, the elastic block, after being pressed by the slider 110, will move in the opposite direction to the movement direction of the slider 110. This reverse movement allows the elastic block to smoothly disengage from the latch 500, thereby allowing the slider 110 to continue its core-pulling action and complete the extraction of the lateral part of the product.
[0032] Furthermore, the elastic block includes: a first trigger block 131 with a second inclined surface 1301; an elastic element 132 connected to the first trigger block 131; and a second trigger block 133 connected to the first trigger block 131 so that when the first trigger block 131 moves in the third direction Z, the second trigger block 133 moves in the second direction Y, and the third direction Z is different from the second direction Y.
[0033] When the first trigger block 131 moves in the third direction Z, the second trigger block 133 will move in the second direction Y. This design ensures that when the slider 110 presses against the first trigger block 131, the second trigger block 133 can move accordingly in the second direction Y, thereby disengaging the latch 500.
[0034] During the mold opening process, the slider 110 moves linearly along the first direction X, pressing against the first trigger block 131. The second inclined surface 1301 of the first trigger block 131 interacts with the first inclined surface 111 of the slider 110, causing the first trigger block 131 to move in the third direction Z. This third direction Z is different from both the first direction X and the second direction Y, and is usually perpendicular to both directions. Due to the transmission connection between the first trigger block 131 and the second trigger block 133, the movement of the first trigger block 131 will drive the second trigger block 133 to move in the second direction Y. The second direction Y is opposite to the first direction X, which means that when the slider 110 presses against the first trigger block 131, the second trigger block 133 will move in the opposite direction, thereby achieving the disengagement of the latch 500.
[0035] The third direction Z is perpendicular to the second direction Y. This design ensures that the elastic block assembly in the mold not only guarantees smooth mold opening but also improves mold operating efficiency and product quality.
[0036] Furthermore, the side of the first trigger block 131 facing the second trigger block 133 is a guide slope 1302. The second trigger block 133 is an elastic block structure with a slot. The guide slope 1302 is inserted into the slot so that the second trigger block 133 can move along the guide slope 1302 to disengage from the latch 500.
[0037] The side of the first trigger block 131 facing the second trigger block 133 is designed as a guide slope 1302, which not only guides the movement of the second trigger block 133, but also ensures the stability and accuracy of the movement.
[0038] The second trigger block 133 has a slot for engaging with the guide ramp 1302 of the first trigger block 131. The slot design ensures that the first trigger block 131 can be accurately engaged, thereby achieving precise motion transmission. The second trigger block 133 adopts an elastic block structure design, which allows it to move flexibly along the guide ramp 1302 after being pushed by it, and to return to its initial position after the movement is completed.
[0039] During the mold opening process, the slider 110 moves linearly along the first direction X, pressing against the first trigger block 131. The guide slope 1302 of the first trigger block 131 contacts the slot of the second trigger block 133 and engages within the slot. This contact allows the second trigger block 133 to move along the guide slope 1302. Since the second trigger block 133 is an elastic block structure, it moves along the guide slope 1302 after being pushed by the first trigger block 131, thereby disengaging the latch 500. The second direction Y is opposite to the first direction X and perpendicular to the third direction Z, ensuring the accuracy and stability of the movement.
[0040] Furthermore, the elastic block also includes a guide shaft 134, which extends in the third direction Z. The trigger block is sleeved on the guide shaft 134 and can move along the guide shaft 134. The first trigger block 131 has a stepped hole, and an elastic element 132 is provided in the stepped hole. The elastic element 132 is a spring, which is sleeved on the guide shaft 134 and abuts against the bottom wall of the stepped hole.
[0041] During the mold opening process, the slider 110 moves linearly along the first direction X, pressing the first trigger block 131. The first trigger block 131 moves along the guide shaft 134 in the third direction Z, and its internal spring is compressed. When the pressure is released, the elastic force of the spring pushes the trigger block back to its initial position. The second trigger block 133 is connected to the first trigger block 131. When the first trigger block 131 moves along the guide shaft 134, the second trigger block 133 moves upward along the guide slope 1302, so that the second trigger block 133 can disengage the latch 500 in the second direction Y.
[0042] This utility model also provides a mold, including: a front mold with a front mold core pull 200; a rear mold; a buckle 500 disposed on the rear mold; and a front mold core pull 200 protection mechanism, wherein the elastic block of the front mold core pull 200 protection mechanism locks the buckle 500 to lock the front mold and the rear mold, or the elastic block disengages from the buckle 500 to unlock.
[0043] When the mold needs to be locked, the elastic block applies pressure through its internal spring or other elastic element 132, locking the latch 500. The locking action of the elastic block ensures a tight fit between the front and rear molds, preventing displacement during injection molding, thereby ensuring product quality and mold stability. When the mold needs to be opened, the trigger block of the front mold core-pulling protection mechanism is pressed by the slider 110 and moves along the guide shaft 134 in the third direction Z. The movement of the trigger block drives the elastic block to move in the second direction Y, causing the elastic block to disengage from the latch 500, thus unlocking the mold.
[0044] The automated front mold core-pulling protection mechanism enables automatic locking and unlocking of the mold, improving production efficiency and reducing the need for manual operation.
[0045] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
[0046] For those skilled in the art, various variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the protection scope of this invention.
