Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an auxiliary demolding mechanism. Background Technology

[0002] In the production process of some electronic products, it is necessary to demold the product after it has been formed. The quality of the demolding directly affects the yield of the product.

[0003] Currently, during the production process, molded products are often difficult to detach from the mold strip due to the large clamping force. It is necessary to use strong knocking or pneumatic demolding jigs to demold the products. However, strong demolding will inevitably damage the products, and in severe cases, it will cause the products to deform or crack. Pneumatic demolding will reduce the production efficiency of the products and increase the production cost. Utility Model Content

[0013] The second slider has a first mating hole, and the second inclined lever is inserted into the first mating hole for limiting. The second inclined lever can drive the second slider to move by pushing against the inner wall of the first mating hole.

[0014] Preferably, the auxiliary demolding mechanism further includes a limiting component connected to the lower mold, the limiting component being configured to drive the second slider to stop at an initial position;

[0015] When the upper mold is disengaged from the lower mold and the second slider is in the initial position, the first mating hole is directly opposite the end of the second inclined lever away from the upper mold.

[0016] Preferably, the auxiliary demolding mechanism further includes a third release component, which includes a third inclined lever and a third slider. The third slider is slidably disposed on the lower mold and connected to a third inner mold strip pressed on the top of the product. The third inclined lever is connected to the upper mold.

[0017] During demolding, the third inclined lever moves under the drive of the upper mold. When the third inclined lever moves, it can drive the third inner mold strip to the third demolding position through the third slider. At the third demolding position, the product is separated from the third inner mold strip.

[0018] Preferably, the length direction of the third inclined lever is set at an angle to the moving direction of the upper mold, and the third inclined lever gradually approaches the outer mold strip along the direction closer to the upper mold;

[0019] The third slider has a second mating hole, and the third inclined lever is inserted into the second mating hole for limiting. The third inclined lever can drive the third slider to move by pushing against the inner wall of the second mating hole.

[0025] The beneficial effects of this utility model are as follows:

[0026] The auxiliary demolding mechanism provided by this utility model includes a first release component comprising a first inclined lever and a first slider, and a second release component comprising a second inclined lever and a second slider. Since both the first and second inclined levers are connected to the upper mold, during demolding, the first and second inclined levers can be driven by the upper mold to respectively drive the first and second sliders. During demolding, since the first and second sliders are respectively connected to the first and second inner mold strips, when the upper mold moves, the first and second inclined levers can respectively drive the first and second inner mold strips to move relative to each other through the first and second sliders, thereby causing the first inner mold... The first and second inner mold strips move to the first and second demolding positions, respectively. Since the first inner mold strip partially detaches from the product at the first demolding position, and the second inner mold strip detaches from the product at the second demolding position, this auxiliary demolding mechanism can, through the drive of the upper mold, enable part of the first and second inner mold strips to detach from the product simultaneously from both sides in the early stage of demolding. This reduces the area covered by the mold strips and the molded product, greatly reducing the difficulty of removing the product from the mold strips. The product can be easily removed from the mold strips without strong knocking or the use of other tools, thereby improving production efficiency and product yield. Attached Figure Description

[0049] like Figures 1 to 7 As shown, this utility model provides an auxiliary demolding mechanism, which includes a first demolding component 1 and a second demolding component 2. The first demolding component 1 includes a first inclined lever 11 and a first slider 12. The first slider 12 is slidably disposed on the lower mold and connected to the first inner mold strip 200 covered by the product 100. The outer mold strip 500 is sleeved on the outside of the first inner mold strip 200. The first inclined lever 11 is connected to the upper mold. During demolding, the first inclined lever 11 moves under the drive of the upper mold. When the first inclined lever 11 moves, it can drive the first inner mold strip 200 to the first demolding position through the first slider 12. At the first demolding position, Part of the first inner mold strip 200 detaches from the product 100; the second detachment component 2 includes a second inclined lever 21 and a second slider 22. The second slider 22 is slidably disposed on the lower mold and connected to the second inner mold strip 300 covered by the product 100. The second inner mold strip 300 and the first inner mold strip 200 are disposed opposite to each other on both sides of the product 100. The second inclined lever 21 is connected to the upper mold. When demolding, the second inclined lever 21 moves under the drive of the upper mold. When the second inclined lever 21 moves, it can drive the second inner mold strip 300 to the second demolding position through the second slider 22. At the second demolding position, the second inner mold strip 300 detaches from the product 100.

[0050] In this embodiment, since both the first inclined lever 11 and the second inclined lever 21 are connected to the upper mold, during demolding, the first inclined lever 11 and the second inclined lever 21 can be driven by the upper mold to drive the first slider 12 and the second slider 22 respectively. During demolding, since the first slider 12 and the second slider 22 are connected to the first inner mold strip 200 and the second inner mold strip 300 respectively, when the upper mold moves, the first inclined lever 11 can drive the first inner mold strip 200 to move to the first demolding position through the first slider 12, and the second inclined lever 21 can drive the second inner mold strip 300 to move to the second demolding position through the second slider 22. When strip 200 is at the first demolding position, part of the first inner mold strip 200 detaches from the product 100, and when the second inner mold strip 300 is at the second demolding position, the second inner mold strip 300 detaches from the product 100. Therefore, this auxiliary demolding mechanism can, through the drive of the upper mold, enable part of the first inner mold strip 200 and the second inner mold strip 300 to detach from the product 100 from both sides of the product 100 simultaneously in the early stage of demolding. This reduces the coverage area of ​​the mold strips and the molded product 100, greatly reducing the difficulty of subsequently removing the product 100 from the mold strips. The product 100 can be easily removed from the mold strips without strong knocking or the use of other tools, thereby improving production efficiency and product yield.

[0051] Specifically, the outer mold strip 500 is fixedly connected to the lower mold. The outer mold strip 500 has a hollow structure. The first inner mold strip 200 passes through the outer mold strip 500 and is tightly covered by it. The two ends of the first inner mold strip 200 protrude from the outer mold strip 500 along the first direction. The second inner mold strip 300 is disposed on the lower mold. The product 100 is sandwiched between the first inner mold strip 200 and the second inner mold strip 300, and the product 100 is embedded and covered by the first inner mold strip 200 and the second inner mold strip 300 respectively. When the injection mold is closed, the second inner mold strip 300 will move closer to the first inner mold strip 200 along the first direction to compress the product 100 sandwiched between the first inner mold strip 200 and the second inner mold strip 300. This process allows product 100 to be finally formed. The edge of product 100 abuts against the outer mold strip 500 along the first direction. When the injection mold is demolded, the first slider 12 drives the first inner mold strip 200 to move relative to the outer mold strip 500, and the second slider 22 drives the second inner mold strip 300 to move relative to the outer mold strip 500. The two sliders move in opposite directions, causing part of the first inner mold strip 200 and the entire second inner mold strip 300 to detach from product 100. At this time, product 100 is fitted onto the remaining part of the first inner mold strip 200, while the first inner mold strip 200 is still covered by the outer mold strip 500. Finally, the staff can manually remove product 100 from the first inner mold strip 200 and the outer mold strip 500.

[0052] The structures of the first inclined lever 11 and the first slider 12 can be configured according to actual needs, as long as the first inclined lever 11 can drive the first slider 12 to move along the first direction when following the movement of the upper mold. For example, as shown in the figure... Figure 2 As shown, the length direction of the first inclined lever 11 is set at an angle to the moving direction of the upper mold, and along the direction closer to the upper mold, the first inclined lever 11 gradually approaches the outer mold strip 500; the first slider 12 is provided with an abutment pin 13, and the first inclined lever 11 can drive the first slider 12 to move by pushing against the abutment pin 13; it can be understood that since there is an angle between the length direction of the first inclined lever 11 and the moving direction of the upper mold, as the upper mold rises, the first inclined lever 11 will push against the abutment pin 13 and apply a force along the first direction to the abutment pin 13, thereby driving the first slider 12 to move.

[0053] Furthermore, such as Figure 2 , Figure 3 as well as Figure 6 As shown, the first release assembly 1 also includes a first elastic element. An abutment pin 13 is connected to the first slider 12 via the first elastic element. The abutment pin 13 has an abutment slope, and the abutment pin 13 abuts against the first inclined lever 11 via the abutment slope. Specifically, the first slider 12 has a mating groove 121, and the first elastic element is installed on the side wall of the mating groove 121. The abutment pin 13 is connected to the first elastic element, and the first inclined lever 11 is inserted into the mating groove 121 and abuts against the abutment slope of the abutment pin 13. When demolding, the upper mold drives the first inclined lever 11 to rise vertically. The first inclined lever 11 drives the first slider 12 to move along a first direction via the abutment pin 13. During the movement, the first slider 12 drives the first inner mold strip 200 to move along the first direction. During this process, the friction between the first inner mold strip 200 and the product 100 gradually increases until the first inner mold strip 200 moves to the first demolding position. At this point, the friction between the first inner mold strip 200 and the product 100 is greater than the elastic force of the first elastic element. Then, the first inclined lever 11 presses the abutting pin 13 back through the abutting inclined surface. The first inclined lever 11 and the abutting pin 13 are no longer interfering with each other. Therefore, the first slider 12 cannot be driven by the first inclined lever 11 through the abutting pin 13. At this time, the first slider 12 stops moving.

[0054] The structure of the second inclined lever 21 and the second slider 22 can be set according to actual needs, as long as it ensures that the second inclined lever 21 can drive the second slider 22 to move along the first direction when following the movement of the upper mold. For example, such as Figure 1 , Figure 4 and Figure 6As shown, the length direction of the second inclined lever 21 is set at an angle to the moving direction of the upper mold, and along the direction closer to the upper mold, the second inclined lever 21 gradually approaches the outer mold strip 500; the second slider 22 has a first mating hole 221, and the second inclined lever 21 is inserted into the first mating hole 221 for limiting. The second inclined lever 21 can drive the second slider 22 to move by pushing against the inner wall of the first mating hole 221. Specifically, since the second inclined lever 21 is inclined, when the second inclined lever 21 is raised with the upper mold, it can apply a force along the first direction to the inner wall of the first mating hole 221, thereby pushing the second slider 22 away from the outer mold strip 500 along the first direction until the second inclined lever 21 is completely disengaged from the first mating hole 211. At this time, the second inner mold strip 300 moves to the second demolding position under the drive of the second slider 22.

[0055] like Figure 1 , Figure 4 and Figure 6 As shown, in order to facilitate the smooth vertical insertion of the second inclined lever 21 into the first mating hole 221 during the next mold closing operation, thereby ensuring the continuous and automated operation of the demolding and mold closing operations, the auxiliary demolding mechanism also includes a limiting component 4. The limiting component 4 is connected to the lower mold and is configured to drive the second slider 22 to stop at the initial position. When the upper mold is disengaged from the lower mold and the second slider 22 is in the initial position, the first mating hole 221 is directly opposite the end of the second inclined lever 21 away from the upper mold.

[0056] The specific structure of the limiting component 4 can be set according to actual needs, as long as it can ensure that the second slider 22 stops at the initial position after the upper mold and lower mold are completely separated. For example, such as Figure 1 , Figure 4 and Figure 6As shown, the limiting component 4 includes a second elastic element 41, a connecting pin 42, and a mounting block 43. The mounting block 43 is connected to the lower mold, and the connecting pin 42 passes through the mounting block 43 and is fixedly connected to the second slider 22. One end of the second elastic element 41 abuts against the mounting block 43 along the first direction, and the other end of the second elastic element 41 abuts against the head of the connecting pin 42 along the first direction. The second elastic element 41 can apply an elastic force away from the outer mold strip 500 to the head of the connecting pin 42. Specifically, the second elastic element 41 is a compression spring, and the second elastic element 41 passes through the connecting pin 42. When demolding, the upper mold drives the second inclined lever 21 to rise vertically, and the second inclined lever 21 applies a force away from the outer mold strip 500 along the first direction to the second slider 22. At the same time, the second elastic element 41 also... The connecting pin 42 applies an elastic force in the same direction to the second slider 22, assisting the second slider 22 in driving the second inner mold strip 300 to move to the second demolding position, thereby reducing the resistance of the upper mold during demolding. When the second inner mold strip 300 moves to the second demolding position, the second slider 22 moves to the initial position. The second slider 22 at the initial position abuts against the mounting block 43 along the first direction. At this time, the upper mold stops moving, the upper mold and the lower mold are completely separated, and the second inclined lever 21 is aligned vertically with the first mating hole 221. Since the second elastic element 41 can always apply an elastic force to the second slider 22 through the connecting pin 42, the second slider 22 can always be in the initial position, preventing the second slider 22 from sliding due to external forces.

[0057] Furthermore, such as Figure 1 , Figure 4 as well as Figure 7 As shown, the auxiliary demolding mechanism also includes a third demolding component 3, which includes a third inclined lever 31 and a third slider 32. The third slider 32 is slidably disposed on the lower mold and connected to the third inner mold strip 400 pressed on the top of the product 100. The third inclined lever 31 is connected to the upper mold. When demolding, the third inclined lever 31 moves under the drive of the upper mold. When the third inclined lever 31 moves, it can drive the third inner mold strip 400 to the third demolding position through the third slider 32. At the third demolding position, the product 100 is disengaged from the third inner mold strip 400.

[0058] Specifically, in order to enable the injection mold to produce complex structure products 100, a third inner mold strip 400 is provided on the lower mold of some injection molds. The third inner mold strip 400 covers the top of the product 100, and the third inner mold strip 400 and the first inner mold strip 200 are arranged opposite to each other on both sides of the product 100. When the mold is closed, the third inner mold strip 400 will move closer to the first inner mold strip 200 along the first direction to press the product 100 from above and make the product 100 finally formed. When demolding, the upper mold drives the third inclined lever 31 to rise vertically. The third inclined lever 31 drives the third inner mold strip 400 to move to the third demolding position through the third slider 32, so that the third inner mold strip 400 is separated from the product 100, reducing the difficulty of manually removing the product 100 from the third inner mold strip 400 later.

[0059] The structures of the third inclined lever 31 and the third slider 32 can be configured according to actual needs, as long as the third inclined lever 31 can drive the third slider 32 to move along the first direction when following the movement of the upper mold. For example, as shown... Figure 1 , Figure 4 and Figure 7 As shown, the length direction of the third inclined lever 31 is set at an angle to the moving direction of the upper mold. Along the direction closer to the upper mold, the third inclined lever 31 gradually approaches the outer mold strip 500. The third slider 32 is provided with a second mating hole 321. The third inclined lever 31 is limited and inserted into the second mating hole 321. The third inclined lever 31 can drive the third slider 32 to move by pushing against the inner wall of the second mating hole 321.

[0060] Furthermore, such as Figure 2 , Figure 4 and Figure 7As shown, the auxiliary demolding mechanism also includes a top clearance component 5, which includes an abutment lever 51 and a clearance slider 52. The abutment lever 51 is connected to the upper mold, and the clearance slider 52 is slidably disposed in the lower mold and connected to the third inner mold strip 400. During demolding, the abutment lever 51 moves under the drive of the upper mold. When the abutment lever 51 moves, it can drive the third inner mold strip 400 from the third demolding position to the clearance position through the clearance slider 52. At the clearance position, there is no overlapping area between the third inner mold strip 400 and the product 100 in the vertical direction. In this embodiment, when the third inner mold strip 400 moves to the third demolding position under the drive of the third slider 32, the third inner mold strip 400 is no longer tightly wrapped with the product 100. However, due to the size of the product 100 and the structure of the lower mold, there is still an overlap area between the third inner mold strip 400 and the product 100 in the vertical direction. These overlap areas will hinder the removal of the product 100 from the lower mold. The top clearance component 5 can move the third inner mold strip 400 to the clearance position, so that the third inner mold strip 400 and the product 100 do not interfere with each other in the vertical direction, thereby greatly facilitating the removal of the product 100 from the lower mold.

[0061] For example, such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the abutment lever 51 is provided with a slanted bend 511, and the avoidance slider 52 has a drive hole 521. The abutment lever 51 is inserted into the drive hole 521 for a limiting position. The slanted bend 511 can drive the avoidance slider 52 to move by pushing against the inner wall of the drive hole 521. Specifically, the slanted bend 511 is provided at the bottom of the abutment lever 51. The slanted bend 511 is inclined in the second direction and gradually approaches the product 100 along the direction closer to the upper mold. When demolding, the abutment lever 51 is on the upper mold. Driven by the mold, the lower edge is raised vertically. Before the third inner mold strip 400 moves to the third demolding position, the inclined bend 511 does not contact the drive hole 521. Therefore, the avoidance slider 52 does not move in the second direction. After the third inner mold strip 400 moves to the third demolding position, the abutment lever 51 continues to rise under the drive of the upper mold. Then, the inclined bend 511 abuts against the inner wall of the drive hole 521 and pushes the avoidance slider 52 to move in the second direction until the third inner mold strip 400 is driven to move to the avoidance position.

[0062] Specifically, such as Figure 5As shown, the top clearance assembly 5 also includes a connecting rod 53. One end of the connecting rod 53 is fixedly connected to the third inner mold strip 400, and the other end of the connecting rod 53 is slidably connected to the clearance slider 52 along the first direction. The third inner mold strip 400 is slidably disposed on the third slider 32 along the second direction. When the third slider 32 moves, it can drive the connecting rod 53 to move along the first direction through the third inner mold strip 400. When the clearance slider 52 moves, it can drive the third inner mold strip 400 to move along the second direction through the connecting rod 53. In this embodiment, the third slider 32 is provided with a horizontal sliding groove along the second direction, and the third inner mold strip 400 is provided with a fitting protrusion that matches the horizontal sliding groove. The third inner mold strip 400 can slide relative to the third slider 32 through the cooperation of the fitting protrusion and the horizontal sliding groove. The avoidance slider 52 is provided with a vertical sliding rail along the first direction, and the connecting rod 53 is provided with a fitting groove that matches the vertical sliding rail. The connecting rod 53 can slide relative to the avoidance slider 52 through the cooperation of the vertical sliding rail and the fitting groove.

[0063] During demolding, the specific movement process of the top clearance component 5 is as follows: First, the third inclined lever 31 moves under the drive of the upper mold, and drives the third inner mold strip 400 to move along the first direction through the third slider 32. Since the connecting rod 53 is fixedly connected to the third inner mold strip 400 and the connecting rod 53 is in sliding engagement with the clearance slider 52, the connecting rod 53 slides relative to the clearance slider 52 during the movement of the third inner mold strip 400 along the first direction; when the third inner mold strip 400 moves to the third demolding position... The third inner mold strip 400 is separated from the product 100. At this time, the upper mold continues to rise, and the inclined bend 511 on the lever 51 pushes against the inner wall of the drive hole 521 in the second direction, thereby pushing the avoidance slider 52 to slide in the second direction. Since the third inner mold strip 400 slides and engages with the third slider 32 in the first direction, the avoidance slider 52 drives the third inner mold strip 400 to move relative to the third slider 32 through the connecting rod 53, thereby causing the third inner mold strip 400 to move from the third demolding position to the avoidance position.

[0064] This embodiment also provides an injection mold, which includes an upper mold, a lower mold, a first inner mold strip 200, a second inner mold strip 300, a third inner mold strip 400, an outer mold strip 500, and the aforementioned auxiliary demolding mechanism. The first inner mold strip 200 includes a first forming part 210 and a second forming part 220. The first forming part 210 partially surrounds the second forming part 220, and a compression spring is provided between the first forming part 210 and the second forming part 220. The first forming part 210 is movable relative to the second forming part 220, and the first forming part 210 passes through the outer mold strip 500. The molded product 100 is sandwiched between the first inner mold strip 200, the second inner mold strip 300, and the third inner mold strip 400. During demolding, the auxiliary demolding mechanism can separate the product 100 from the first mold part 210, the second inner mold strip 300, and the third inner mold strip 400. The second mold part 220 is still wrapped by the product 100. Then, the operator removes the outer mold strip 500 wrapped by the first inner mold strip 200 from the lower mold, fixes the outer mold strip 500, and pushes the first mold part 210. The first mold part 210 can then approach the second mold part 220 and push out the product 100 wrapped by the second mold part 220, thus finally completing the separation of the product 100 from the injection mold.
