New description: [New technical field] This creation involves the field of mold technology, especially involving a mold with an automatic unlocking mechanism. [Prior Art] A mold is an indispensable part in the processing of plastic products. The quality of the mold determines the quality of the plastic product. After the mold is formed, during the handling and frame mold debugging process, the newly formed mold is often damaged due to the protection of the mold. In order to solve the above problems, an automatic unlocking mechanism has been devised to prevent damage to the mold due to bumps in handling and frame mold debugging. However, the conventional automatic unlocking mechanism has a complicated structure, which results in a complicated mold opening and clamping process, and a high cost. [New Content] The purpose of the present invention is to provide a mold having an automatic unlocking mechanism in view of the above-mentioned deficiencies of the prior art, which has a simple structure, convenient mold opening and mold clamping, and low cost. In order to achieve the above object, the technical solution of the present invention is to provide a mold with an automatic unlocking mechanism, including a mother template, a male template corresponding to the mother template, a female die fishing, a male die hanging, and an automatic unlocking mechanism. The female die fishing is set on the mother template, and the male die hook is set on the male template. The automatic unlocking mechanism includes a push plate and an elastic member. The push plate is slidably disposed on the female die plate, and one end of the push plate abuts against the female die hook, and the female die hook slides along the unlocking die direction to push the push plate to slide left and right. The male mold hook and the push plate are detachably engaged, one end of the elastic member is mounted on the female template, and the other end of the elastic member is in contact with the push plate. Further, the push plate has a sloped surface and an abutting surface, and the female die hook has a hook 3 M428844 portion, and the hook portion slides along the inclined surface to interfere with the abutting surface. Further, the elastic member is a spring. In another preferred embodiment of the present invention, the automatic unlocking mechanism further includes a stopping block disposed on the female template, the pushing plate having a notch, and one end of the stopping block is inserted into the notch to define the sliding of the pushing plate stroke. Further, the mold having the automatic unlocking mechanism further includes an upper fixing plate located above the mother die plate, and the top of the female die hook is extended from the mother die plate and mounted to the upper fixing plate. Further, the mold having the automatic unlocking mechanism further includes a pull rod, the pull rod is mounted to the upper fixing plate and the mother template, and the pull rod moves in the direction of the unlocking mold with the upper fixing plate. As described above, the mold having the automatic unlocking mechanism has an automatic unlocking mechanism. When the mold is opened, the female hook moves in the mold opening direction, pushing the push plate to the left and compressing the elastic member, and when the push plate slides to the left. At a certain distance, the male mold hook is separated from the push plate and continues to move in the mold opening direction, thereby realizing the mold opening; when the mold is locked, the female mold hook and the male mold hook are moved along the mold clamping direction, and the elastic member functions. Push the push plate to the right until it is hooked back to the male mold to achieve clamping. The mold with the automatic unlocking mechanism has a simple structure, convenient mold opening and mold clamping, and low cost. The present invention will become more apparent from the following description, taken in conjunction with the accompanying drawings, [Embodiment] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals indicate like elements. Referring to the first figure and the second figure, an embodiment of the mold having the automatic unlocking mechanism includes an upper fixing plate 10, a tie rod 12, a mother template 14, a male template 16 corresponding to the mother template 4 M428844 14, and a female mold. The hook 18, the male mold hook 2〇 and the automatic unlocking mechanism 22, the upper fixing plate 1〇 is located above the female die plate 14 and the top of the female die hook 18 protrudes from the female die plate 14 and is mounted on the upper fixing plate 1〇, and the pull rod 12 is mounted on The upper plate 10 and the female die plate 14 are fixed, and the pull bar 12 moves along the upper fixed plate 1 in the direction of the open mold. The female die hook 18 is disposed on the female die plate 14, and the male die hook 20 is disposed on the male die plate 16 to automatically unlock the die. The mechanism 22 is disposed on the mother template 14. Specifically, the automatic unlocking mechanism 22 includes a pushing plate 221, an elastic member 222, and a stopping block 223. The pushing plate 221 is slidably disposed on the female die plate 14, and one end of the pushing plate 221 is in contact with the female die hook 18, the female die. When the hook 18 moves in the direction of the unlocking die, the push plate 221 is pushed to slide left and right. The male die hook 2 is detachably engaged with the push plate 221, one end of the elastic member 222 is mounted on the female die plate 14, and the other end of the elastic member 222 is opposite to the push plate. 221, a stopper 223 is disposed on the mother die plate 14. Specifically, referring to the fourth figure, the push plate 221 has a slope 221a, a contact surface 221b, and a notch 221c. The female die fishing 18 has a hook portion (not shown), and the hook portion slides along the slope 221a and the contact surface 221b. In opposition, one end of the stopper 223 is inserted into the notch 221c to define the sliding stroke of the push plate 221. Preferably, the elastic member 222 is a spring. Referring now to the second to fourth figures, a detailed process of the mold unlocking mold having the automatic unlocking mechanism is described. As shown in the second figure, in the mode-locking state, the upper fixing plate 10, the female die plate 14 and the male die plate 16 are press-fitted to each other, and the hook portion of the female die hook 18 abuts the hook portion of the female die plate 14' male die hook 20 and pushes. The plate 221 is engaged. At this time, the elastic member 222 is in a natural state, and the stopper 223 is located at the leftmost end of the notch 221c. When the mold is opened, the upper fixing plate 10 and the mother template 14 are first separated, that is, the tie rod 12 and the female mold hook 18 are moved in the I direction (ie, the mold opening direction) shown in the second figure, and the hook portion of the female mold hook 18 is pushed along the push plate. The inclined surface 221a of the 221 is moved upward, thereby pushing the 5 M428844 moving plate 221 to slide to the left (in the direction of the drawing II) and compressing the elastic member 222 so that the elastic member 222 has a rightward elastic restoring force. When the push plate 221 is slid to the left to a certain distance, the male die hook 20 is disengaged from the push plate 221 to reach the half-open state as shown in the third figure. At this time, the stopper 223 is at the intermediate position of the notch 221c. Thereafter, the female die hook 18 continues to move in the direction of the drawing I until it reaches the fully open state as shown in the fourth figure. As shown in the fourth figure, when the mold is opened, the upper fixing plate 10, the female die plate 14 and the male die plate 16 are completely separated from each other, and the hook portion of the male die hook 20 is completely separated from the push plate 221, and the hook portion of the female die hook 18 is completely removed. The elastic member 222 is in the maximum compression state against the abutting surface 221b of the push plate 221, and the stopper 223 is located in the middle of the notch 221c. ® When clamping, the upper fixing plate 1〇, the female template 14 and the male template 16 as shown in the fourth figure are close to each other, and the hook portion of the female hook 18 moves downward along the inclined surface 221a of the pushing plate 221, in the elastic member. Under the action of 222, the push plate 221 is pushed to the right until the push plate 221 and the male die hook 20 are re-engaged, returning to the mode-locked state shown in the second figure. It should be noted that, in the above-described mold clamping process, the setting of the stopper block 223 can effectively prevent the push plate 221 from sliding too far to the right under the elastic action of the elastic member 222. As described above, the mold having the automatic unlocking mechanism has a simple mold structure, is easy to open and mold, and has low cost. The present invention has been described above in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations in accordance with the nature of the present invention.
