For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.
[0031] Reference Figure 1 As shown, an embodiment of the present application provides a mold structure, including:
[0032] A male mold fixing plate 1 and a female mold fixing plate 2 are arranged opposite to each other, and a product 3 is arranged between the male mold fixing plate 1 and the female mold fixing plate 2;
[0033] The male mold fixing plate 1 is connected to a male mold plate 11, and the female mold fixing plate 2 is connected to a female mold plate 21. The male mold plate 11 and the female mold plate 21 are arranged relatively between the male mold fixing plate 1 and the female mold fixing plate 2.
[0034] A first stopper 211 and a guide post 212 are fixedly connected to the side wall of the female mold fixing plate 2 facing the male mold plate 11. The first stopper 211 and the guide post 212 are arranged to pass through the female mold plate 21. The guide post 212 is inclined toward the direction close to the first stopper 211, and the guide post 212 is arranged to pass through the male mold plate 11.
[0035] The outer wall of the guide column 212 is sleeved with a slider 213, the slider 213 contacts the product 3, the side wall of the slider 213 adjacent to the product 3 contacts the male template 11 and the female template 21 respectively, and the side wall of the slider away from the product 3 contacts the first limiter 211;
[0036] The second limiting member 12 and the third limiting member 214 are respectively fixedly connected to the male mold fixing plate 1 and the female mold fixing plate 2. The second limiting member 12 and the third limiting member 214 are both provided with a protruding end. The protruding end of the second limiting member 12 contacts the female mold plate 21, and the protruding end of the third limiting member 214 contacts the male mold plate 11.
[0037] A stopper 215 is elastically connected to the mother template 21, and the stopper 215 extends toward the third limiting member 214. The stopper 215 is located between the second limiting member 12 and the raised end on the third limiting member 214, and the stopper 215 is inclined toward the side wall of the raised end on the third limiting member 214, so that the stopper 215 can shrink under the squeezing of the raised end of the third limiting member 214.
[0038] In the present application, those skilled in the art can arrange that the female mold fixing plate 2 is installed relative to the male mold fixing plate 1. There is an installation space between the male mold fixing plate 1 and the female mold fixing plate 2.
[0039] Furthermore, the male template 11 and the female template 21 are connected in the installation space. Specifically, the male template 11 is connected to the male template fixing plate 1, and the female template 21 is connected to the female template fixing plate 2.
[0040] By means of the above structure, the male template 11 and the female template 21 are arranged opposite to each other. A first limiter 211 and a guide post 212 are fixedly connected to the female template fixing plate 2, and the first limiter 211 and the guide post 212 extend toward the position of the male template 11. The first limiter 211 and the guide post 212 extend to penetrate the female template 21. The guide post 212 is inclined toward the direction close to the first limiter 211. Furthermore, the guide post 212 continues to extend to penetrate into the male template 11.
[0041] It is understandable that the first stopper 211 and the guide post 212 can slide relative to the contacting part of the mother template 21. Thus, the mother template can move relative to the first stopper 211 and the guide post 212 during the mold opening process.
[0042] Those skilled in the art sleeve a slider 213 on the outer wall of the guide column 212. The slider 213 contacts the product 3, and then the product 3 can be formed. The slider 213 contacts the male mold plate 11 and the female mold plate 21 adjacent to the wall surface that contacts the product 3. Further, the slider 213 can move along the wall surface of the male mold plate 11.
[0043] according to Figure 1 The second limiting member 12 is fixedly connected to the male mold fixing plate 1, and the third limiting member 214 is fixedly connected to the female mold fixing plate 2. The second limiting member 12 and the third limiting member 214 are both provided with a protruding end, and the protruding end of the second limiting member 12 abuts against the female mold plate 21, and the protruding end of the third limiting member 214 abuts against the male mold plate 11.
[0044] In one embodiment, the protruding end of the second limiting member 12 is arranged at a position away from the connection between the second limiting member 12 and the male mold fixing plate 1, and the protruding end of the third limiting member 214 is arranged at a position away from the connection between the third limiting member 214 and the female mold fixing plate 2.
[0045] Those skilled in the art also set a stopper 215 on the outer wall of the mother template 21. The stopper 215 is elastically connected to the mother template 21. That is, the stopper 215 can move away from the mother template 21 and move close to the mother template 21.
[0046] Furthermore, the stopper 215 extends toward the position of the third stopper 214. The stopper 215 is elastically connected to the mother template 21 so that when the stopper 215 moves toward the mother template 21 to the maximum stroke, the stopper 215 does not produce protruding interference on the wall surface of the mother template 21 toward the third stopper 214.
[0047] According to the above structure, during the mold opening process, the male mold fixing plate 1 and the female mold fixing plate 2 move away from each other. During the process of the male mold fixing plate 1 and the female mold fixing plate 2 moving away from each other, the second stopper 12 and the third stopper 214 move relatively. Moreover, the first stopper 211 and the guide pillar 212 withdraw.
[0048] Specifically, during the mold opening process, the first stopper 211 moves in a direction away from the slider 213. The guide post 212 also moves along the inner wall of the slider 213 in a direction away from the slider 213. It can be understood that when the first stopper 211 moves to a position where it does not contact the slider 213, the slider 213 can move in a direction away from the product 3.
[0049] In one embodiment, the guide post 212 is tilted toward the direction close to the first stopper 211. That is, in the process of the guide post 212 moving away from the slider 213, in the process of the side wall of the guide post 212 and the inner wall of the slider 213 being pressed, the slider 213 can be moved away from the product 3 along the male template 11. Then, the slider 213 can be separated from the product 3.
[0050] Further, in the process of the mold continuing to open, the female mold fixing plate 2 continues to move in the direction away from the male mold fixing plate 1. Among them, the second limiter 12 and the third limiter 214 continue to move relative to each other. It can be understood that the second limiter 12 is fixedly connected to the male mold fixing plate 1, and the third limiter 214 is fixedly connected to the female mold fixing plate 2. Then, in the process of the female mold fixing plate 2 and the male mold fixing plate 1 moving away from each other, the second limiter 12 and the third limiter 214 move synchronously.
[0051] In the above structure, the stopper 215 is disposed between the second stopper 12 and the third stopper 214, and the protruding end of the second stopper 12 contacts the female template 21, and the protruding end of the third stopper 214 contacts the male template 11. That is, during the mold opening process, the second stopper 12 and the third stopper 214 perform continuous relative movement.
[0052] In the process of continuous relative movement between the second stopper 12 and the third stopper 214, the stopper can block the protruding ends of the second stopper 12 and the third stopper 214. In the above structure, the stopper 215 is inclined toward the side wall of the protruding end of the third stopper 214. That is, when the protruding end of the third stopper 214 contacts the stopper 215, the third stopper 214 squeezes the stopper 215. The stopper 215 is compressed in the squeezed state and can be retracted into the mother template 21.
[0053] In the above process, after the stopper 215 is squeezed and compressed, the second stopper 12 and the third stopper 214 can continue to move, thereby completely separating the male mold fixing plate 1 from the female mold fixing plate 2. Figure 2 and Figure 3 It can be seen that after the female mold fixing plate 2 is completely separated from the male mold fixing plate 1, the female mold plate 21 can be driven to continue to separate, thereby making the molds completely separated.
[0054] In summary, during the process of mold opening, the female mold fixing plate 2 and the male mold fixing plate 1 move away from each other. The movement of the female mold fixing plate 2 can drive the first limiter 211 and the guide column 212 to move, and then the slider 213 can be moved. The movement of the slider 213 can separate the slider 213 from the product 3. In other words, the movement of the female mold fixing plate 2 can separate the product 3 from the slider and the components connected to the female mold fixing plate 1 first. As the female mold fixing plate 2 continues to move, the raised end of the third limiter 214 squeezes the stopper 215, and then the third limiter 214 can be completely separated from the second limiter 12. Then, the female mold plate 21 can be completely separated from the male mold.
[0055] It is worth noting that after the female mold fixing plate 2 is completely separated from the male mold fixing plate 1, the female mold plate 21 and the slider 213 are connected to the female mold fixing plate 2. In addition, the stopper 215 is only provided with an inclined surface at the protruding end facing the third limiting member 214, so that when the second limiting member 12 and the stopper 215 first contact, a resisting structure is formed with the protruding end of the second limiting member 12, so that the mold opening process can be effectively kept stable.
[0056] In the above mold opening process, the product 3 is first separated from the parts in the female mold, and then the product 3 is gradually separated from the slider 213. When the slider 213 and the product 3 are separated to a suitable distance, the female mold fixing plate 2 is completely separated from the male mold fixing plate 1. This can effectively avoid scratching the product 3 during the mold opening process.
[0057] In the above process, the protruding end of the third limiting member 214 presses the stopper 2 so that the stopper 2 retracts into the inner wall of the female template 21. Figure 3 After the female mold fixing plate 2 is completely separated from the male mold fixing plate 1, the protruding end of the third limiting member 214 can continue to press the stopper 215, thereby enabling the mold to be closed smoothly.
[0058] Specifically, during the mold closing process, the female mold fixing plate 2 and the male mold fixing plate 1 are close to each other, so that the second limiter 12 and the third limiter 214 can overlap. During the process of the female mold plate 21 and the male mold plate 11 being in conflict, the female mold plate 21 moves toward the direction where the female mold fixing plate 2 is located, so that the stopper 2 can extend out of the side wall of the female mold plate 21 away from the product 3 under the action of the elastic member, and at the same time, the guide column 212 and the first limiter 211 move toward the position where the male mold plate 11 is located. The above process can stably achieve mold closing.
[0059] In the above structure, the first position-limiting member 211 is in conflict with the slider 213. Preferably, the middle position of the male template 11 is recessed in a direction away from the female template 21 to form a fixing groove 111, and a cushion block 4 is installed in the fixing groove 111, and the cushion block 4 is in conflict with the first position-limiting member 211. According to the above structure, the cushion block 4 can be arranged to conflict with the first position-limiting member 211 while the first position-limiting member 211 is in conflict with the slider 213, thereby making the structure inside the mold more stable.
[0060] Preferably, the contact surface between the first stopper 211 and the slider 213 is set as an inclined surface. Therefore, during the mold opening process, when the first stopper 211 starts to move in a direction away from the slider 213, the slider 213 can directly start to move in a direction away from the product 3 under the action of the guide pillar 212. Therefore, the mold opening process is more stable.
[0061] More preferably, the inclination angle of the inclined surface is the same as the inclination angle of the guide post 212. That is, when the guide post 212 withdraws from the slider 213, the slider 212 can keep in contact with the inclined surface while moving along the male mold plate 11 without being squeezed. This can avoid the mold opening jamming caused by the slider 212 squeezing the outer wall of the first stopper 211 during the movement of the slider 212. This further makes the mold opening process more stable.
[0062] In the above embodiment, the guide post 212 passes through the slider 213 and passes through the male mold plate 11. Preferably, a through hole 112 is opened in the middle of the male mold plate 11, and the guide post 212 passes through the through hole 112. Thus, the guide post 212 can avoid collision and extrusion with the male mold plate 11 during the process of mold opening and mold closing. Thus, the service life of the mold can be greatly extended.
[0063] In the above-mentioned mold opening and mold closing process, the guide pillar 212 needs to penetrate the slider 213 and exit the inner wall of the slider 213. Preferably, the slider 213 is slidably connected to the guide pillar 212. Preferably, the slider 213 is slidably connected to the male mold plate 11. This can effectively make the mold opening and mold closing process more stable.
[0064] During the process of mold opening and mold closing, the second stopper 12 and the third stopper 214 move relative to each other. Preferably, the plane where the second stopper 12 is located is parallel to the plane where the third stopper 214 is located, and the distance from the second stopper 12 to the male template 11 is greater than the distance from the third stopper 214 to the female template 21. This can effectively prevent the second stopper 12 and the third stopper 214 from interfering with each other during the movement. The above-mentioned setting can not only improve the service life of the mold, but also make the process of mold opening and mold closing more stable.
[0065] Preferably, the side wall of the female template 21 close to the cushion block 4 is recessed in a direction away from the male template 11 to form a groove, and the cushion block 4 extends toward the groove and penetrates into the groove. The above structure can make the cushion block 4 cooperate with the groove during the mold closing process, thereby making the distribution of the internal structure of the mold more reasonable and making the cooperation between the internal structures of the mold more stable.
