Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding technology, specifically to an injection mold for automotive parts. Background Technology
[0002] In the automotive industry, injection molds are primarily used in the production of automotive interior trim and body panels. An injection mold typically consists of two parts: a moving mold and a fixed mold. The moving mold is mounted on the moving platen of the injection molding machine, while the fixed mold is mounted on the fixed platen. During injection molding, the moving and fixed molds close to form the gating system and mold cavity. When the mold opens, the moving and fixed molds separate, and the product is separated from the mold cavity by an ejection mechanism.
[0003] like Figure 1 The automotive part shown has a complex structure and many undercuts. Traditional molds typically use a slanted ejector mechanism to eject it from the mold cavity. However, this method is not suitable for demolding this part. In particular, when one of the openings in the part has an irregular flange, the flange's thin wall and long length make it easy to damage the flange surface if a conventional slanted ejector mechanism is used for demolding. Therefore, a new and reasonable demolding structure is urgently needed. Summary of the Invention
[0004] The purpose of this invention is to provide an injection mold for automotive parts that is simple in structure, easy to operate, and does not easily damage the flange of the product.
[0005] To achieve the above objectives, this utility model provides an injection mold for automotive parts, comprising a fixed mold and a moving mold, with a cavity provided between the fixed mold and the moving mold, and a first demolding mechanism provided between the fixed mold and the moving mold. The first demolding mechanism includes a first slider, a second slider, a first inclined ejector, and a spring ejector assembly. The first inclined ejector is connected to the fixed mold, the first slider is disposed on the moving mold, and the first inclined ejector can drive the first slider to move along the direction perpendicular to the mold opening. The second slider is inclinedly disposed on the first slider, and the spring ejector assembly is disposed on the first end of the second slider. The spring ejector assembly includes an ejector block, a first connecting member, and a first elastic member. A groove is provided between the ejector block and the second slider, and the groove communicates with the cavity. The first connecting member is connected between the ejector block and the second slider, and the first elastic member elastically abuts against the second slider and the ejector block, so that the second slider can move relative to the ejector block.
[0006] As can be seen from the above scheme, with the above settings, during mold opening, the first inclined ejector drives the second slider to move through the first slider. During this period, under the elastic force of the first elastic element, the ejector block pushes the product towards the fixed mold, which temporarily fixes the product. As the second slider continues to move, one side wall of the flange portion at the hole of the product can first separate from the second slider, realizing the first demolding. Then, the second slider drives the ejector block to move together through the first connecting member, so that the other side wall of the flange portion at the hole of the product separates from the ejector block, realizing the second demolding. This embodiment adopts a two-stage demolding for the flange portion of the hole wall, which helps to avoid damage to the flange portion of the product and improve product quality. This utility model also has the advantages of simple structure and convenient operation.
[0007] A further embodiment is that the first end of the second slider is provided with a receiving groove, and the groove wall of the receiving groove is provided with a first stepped groove; the top block is provided in the receiving groove, and the side wall of the top block is provided with a second stepped groove, and the second stepped groove is provided in correspondence with the first stepped groove to form a groove.
[0008] As can be seen from the above scheme, the above settings allow the formed flange to be supported on the bottom of the first and second stepped grooves simultaneously, which facilitates the separation of the side walls of the flange for demolding.
[0009] A further embodiment is that the first slider has a first inclined groove, the extension direction of the first inclined groove intersects with the mold opening direction, the second slider extends inclinedly into the cavity, the second end of the second slider is slidably disposed in the first inclined groove, and the extension direction of the second slider is perpendicular to the extension direction of the first inclined groove; the first end of the first connector passes through the top block and is fixedly connected to the second slider, the second end of the first connector is provided with a blocking part, and the top block can move relative to the two ends of the first connector by a first preset distance.
[0010] As can be seen from the above scheme, the opening and closing action of the second slider is realized by using the inclined slide groove, which has the advantages of simple structure and convenient operation. By setting the blocking part, it is used to limit the separation of the first connecting piece from the top block on the one hand, and to delay the movement of the top block together on the other hand.
[0011] A further embodiment includes a second demolding mechanism between the fixed mold and the moving mold. The second demolding mechanism includes a first slide block, a second slide block, a first inclined guide block, and a second inclined guide block. Both the first and second inclined guide blocks are connected to the fixed mold. The first slide block is mounted on the moving mold. The first inclined guide block can drive the first slide block to move along the direction perpendicular to the mold opening direction. The second slide block is inclinedly mounted on the first slide block. The second inclined guide block can drive the second slide block to move outwards at an angle by a second preset distance on the first slide block. During mold opening, the second inclined guide block first drives the second slide block to move, and then the second inclined guide block drives the first and second slide blocks to move synchronously.
[0012] As can be seen from the above scheme, with the above settings, when the mold is opened, the second inclined guide block first drives the second slide to move upward at an angle, so that the second slide is demolded from the product. Then the first inclined guide block drives the first slide to move, which in turn drives the second slide to move synchronously, making it easier to eject the entire product.
[0013] A further proposed solution is that the first inclined guide block is provided with a first straight part and a first inclined part. The first straight part is located on the end of the first inclined part near the fixed mold. The first slide has a first inclined hole. Both the first straight part and the first inclined part are inserted into the first inclined hole, and there is a first safety distance between the hole wall of the first inclined hole and the first straight part. The second inclined guide block is provided with a second inclined part. The second slide has a second inclined hole. The second inclined part is inserted into the second inclined hole and abuts against the hole wall of the second inclined hole.
[0014] As can be seen from the above scheme, with the above settings, since the second inclined part abuts against the wall of the second inclined hole, and there is a first safety distance between the wall of the first inclined hole and the first straight part, the first inclined guide block and the second inclined guide block move simultaneously when the mold is opened. The second inclined guide block can drive the second slide block to move first, and then the first inclined guide block drives the first slide block and drives the second slide block to move synchronously.
[0015] A further proposed solution is that the first slide block is provided with a first limiting block, and the first limiting block is provided with a first protruding ridge; the second slide block is provided with two first limiting grooves arranged along its sliding direction, and the first protruding ridge can be engaged with either of the first limiting grooves.
[0016] As can be seen from the above scheme, with the above settings, when the mold is closed, the first protrusion is embedded in a first limiting groove; when the mold is opened, as the second slide moves, the first protrusion is embedded in another first limiting groove, which plays a limiting role and prevents the second slide from moving down.
[0017] A further embodiment includes a third demolding mechanism between the fixed mold and the moving mold. The third demolding mechanism includes a first slide, a second slide, a first drive, and a second drive. Both the first and second drive are connected to the fixed mold. The first slide is mounted on the moving mold. The first drive can drive the first slide to move along the direction perpendicular to the mold opening direction. The second slide is inclinedly mounted on the first slide. The second drive can drive the second slide to move outward relative to the first slide by a third preset distance. During mold opening, the second drive first drives the second slide to move, and then the first drive drives the first and second slides to move synchronously.
[0018] As can be seen from the above scheme, with the above settings, when the mold is opened, the second driving component first drives the second sliding component to tilt upward, so that the second sliding component is demolded from the product. Then the first driving component drives the first sliding component to move, thereby driving the second sliding component to move synchronously, which facilitates the ejection of the entire product.
[0019] A further embodiment is that the first driving member is provided with a second straight part and a third inclined part. The second straight part is located on the end of the third inclined part near the fixed mold. The first sliding member has a third inclined hole. Both the second straight part and the third inclined part are inserted into the third inclined hole, and there is a second safety distance between the hole wall of the third inclined hole and the second straight part. The second driving member is provided with a fourth inclined part. The second sliding member has a fourth inclined hole. The fourth inclined part is inserted into the fourth inclined hole and abuts against the hole wall of the fourth inclined hole.
[0020] A further proposed solution is that the third demolding mechanism also includes a third driving component, which is connected to the fixed mold. When the mold is closed, the third driving component can drive the second sliding component to tilt and move inward by a fourth preset distance.
[0021] As can be seen from the above scheme, with the above settings, when the mold is closed, the third driving component can drive the second sliding component to tilt downwards, ensuring that the second sliding component moves back into place.
[0022] A further solution is that the first slider is provided with a second limiting member, and the second limiting member is provided with a second protruding ridge; the second slider is provided with two second limiting grooves arranged along its moving direction, and the second protruding ridge can be engaged with either of the second limiting grooves.

[0034] See Figure 1 and Figure 2 In this embodiment, the product 10 to be injection molded is an automotive part, and a first demolding area 101, a second demolding area 102, and a third demolding area 103 are respectively provided at its three corners. The first demolding area 101 includes a through hole 1011, and the wall of the through hole 1011 is provided with a flange 1012. The flange 1012 protrudes downward from the bottom wall of the first demolding area 101, and the wall thickness of the flange 1012 is relatively thin. The second demolding area 102 includes an inclined first flat plate 1021, and the first flat plate 1021 is provided with a hollowed-out circular protrusion 1022. The third demolding area 103 includes an inclined second flat plate 1031, and a through circular hole 1032 is provided on the second flat plate 1031.
[0035] See Figure 3 and Figure 4 and combined Figure 1 This embodiment provides an injection mold for automotive parts, including a fixed mold 1 and a moving mold 2. The fixed mold 1 includes a top plate 11, a fixed mold base 12, and a fixed mold plate 13. The moving mold 2 is disposed below the fixed mold 1 and includes a moving mold plate 21, an ejector plate 22, and a bottom plate 23. The fixed mold plate 13 and the moving mold plate 21 are correspondingly arranged, and a cavity 100 for molding a product 10 is provided between the fixed mold plate 13 and the moving mold plate 21. The fixed mold 1 is provided with a gating channel 14 communicating with the cavity 100.
[0036] A first demolding mechanism 3, a second demolding mechanism 4, and a third demolding mechanism 5 are provided between the fixed mold 1 and the moving mold 2. The first demolding mechanism 3, the second demolding mechanism 4, and the third demolding mechanism 5 are respectively provided for the first demolding area 101, the second demolding area 102, and the third demolding area 103 of the product 10. Specifically, the first demolding mechanism 3 is provided on the first side of the moving mold 2, and the second demolding mechanism 4 and the third demolding mechanism 5 are both provided on the second side of the moving mold 2.
[0037] See Figure 5 and Figure 6 and combined Figure 2 The first demolding mechanism 3 includes a first slider 31, a second slider 32, a first inclined ejector 33, a spring ejector assembly 34, and a stop block 35.
[0038] The first slider 31 is mounted on the moving template 21. One end of the first inclined top 33 is connected to the fixed template 13, and the other end of the first inclined top 33 is obliquely inserted into the first slider 31. The first slider 31 has a first oblique groove 311, the extension direction of which intersects the mold opening direction. In this embodiment, the mold opening direction is vertical, and the extension direction of the first oblique groove 311 is preferably obliquely downward and inward along the mold opening direction. The lower part of the second slider 32 is slidably mounted within the first oblique groove 311, and the second slider 32 extends obliquely upward and inward. The upper part of the second slider 32 is embedded in the cavity 100. A stop block 35 is mounted on the moving template 21 and is located on one side of the second slider 32 to restrict the movement direction of the second slider 32.
[0039] The upper part of the second slider 32 is provided with a receiving cavity 321, which includes a first stepped cavity, a second stepped cavity, and a third stepped cavity that are interconnected. The spring-loaded assembly 34 includes a top block 341, a first connecting member 342, and a first elastic member 343. The top block 341 is disposed in the first stepped cavity, and the first connecting member 342 passes through the top block 341 and the second stepped cavity and connects to the third stepped cavity. The first elastic member 343 is preferably a spring, which is disposed in the second stepped cavity and sleeved on the middle part of the first connecting member 342. That is, the first elastic member 343 elastically abuts against the second slider 32 and the top block 341, so that the top block 341 can move relative to the second slider 32. The head of the first connecting member 342 is provided with a blocking part, which can stop the top block 341, on the one hand preventing the top block 341 from disengaging from the first connecting member 342, and on the other hand limiting the top block 341 to move a first preset distance relative to the second slider 32 between the two ends of the first connecting member 342.
[0040] A groove is formed between the top block 341 and the second slider 32, and the groove communicates with the cavity 100. Specifically, a first stepped groove 3211 is provided on each of the opposite side walls of the receiving cavity 321; a second stepped groove 3411 is provided on each of the opposite side walls of the top block 341. The second stepped groove 3411 is correspondingly provided with and communicates with the first stepped groove 3211 to form a groove, which is used to form the flange portion 1012 of the first demolding area 101 of the product 10.
[0041] When the mold opens, the moving mold 2 moves downward, and the first inclined ejector 33 drives the first slider 31 to move along the vertical mold opening direction, that is, to move outward in the horizontal direction, which in turn drives the second slider 32 to move downward at an angle. During this process, due to the elastic effect of the first elastic element 343, the ejector block 341 can be held in place temporarily, so that the second slider 32 and the flange 1012 are demolded first. After the second slider 32 moves a first preset distance, the blocking part abuts against the ejector block 341. After that, the second slider 32 drives the ejector block 341 to move synchronously through the first connecting member 342, so that the ejector block 341 is demolded from the product 10.
[0042] See Figure 7 and Figure 8 and combined Figure 2 A second demolding mechanism 4 is also provided between the fixed mold 1 and the moving mold 2. The second demolding mechanism 4 includes a first slide block 41, a second slide block 42, a first inclined guide block 43, and a second inclined guide block 44.
[0043] The first slide block 41 is mounted on the moving mold plate 21. The upper part of the first inclined guide block 43 is connected to the fixed mold plate 13, and the lower part of the first inclined guide block 43 is inclinedly inserted into the first slide block 41. The first inclined guide block 43 can drive the first slide block 41 to move along the vertical mold opening direction, that is, to move in the horizontal direction. The upper part of the first slide block 41 is provided with a first inclined surface 411. The second slide block 42 is inclinedly mounted on the first slide block 41. One side of the first inclined surface 411 is provided with a stop part for stopping the second slide block 42. One end of the second slide block 42 extends inclined downward toward the cavity 100. The end of the second slide block 42 is provided with a concave-convex structure that matches the circular protrusion 1022 of the second demolding area 102 of the product 10. The upper part of the second inclined guide block 44 is connected to the fixed mold plate 13, and the lower part of the second inclined guide block 44 is inclinedly inserted into the second slide block 42. The second inclined guide block 44 can drive the second slide block 42 to move inclined outward on the first slide block 41 by a second preset distance.
[0044] During mold opening, the second inclined guide block 44 first drives the second slide block 42 to move a second preset distance on the first inclined surface 411 of the second slide block 42. Then, the first inclined guide block 43 drives the first slide block 41 to move outward in the horizontal direction, thereby driving the second slide block 42 to move synchronously. Specifically:
[0045] The first inclined guide block 43 is provided with a first straight part 431 and a first inclined part 432. The first straight part 431 is located on the end of the first inclined part 432 near the fixed template 13. The first straight part 431 extends a preset length along the mold opening direction, and the first inclined part 432 extends downward and outward along the mold opening direction.
[0046] The first slide block 41 has a first inclined hole 412. When the mold is closed, both the first straight part 431 and the first inclined part 432 are inserted into the first inclined hole 412, and there is a first safety distance between the wall of the first inclined hole 412 and the first straight part 431. When the mold is opened, the first slide block 41 moves downward relative to the first inclined guide block 43. At this time, the first straight part 431 cannot contact the wall of the first inclined hole 412, that is, the first straight part 431 cannot drive the first slide block 41 to move horizontally; until the first inclined part 432 contacts the wall of the first inclined hole 412, the first inclined part 432 can drive the first slide block 41 to move horizontally outward.
[0047] The second inclined guide block 44 is provided with a second inclined portion 411, which extends downward and outward along the mold opening direction; the second slide block 42 is provided with a second inclined hole 421, and the second inclined portion 411 is inserted into the second inclined hole 421. When the mold is closed, the second inclined portion 411 abuts against the outward side wall of the second inclined hole 421; when the mold is opened, the second inclined portion 411 can immediately act on the wall of the second inclined hole 421 to drive the second slide block 42 to move a second preset distance in the first instant.
[0048] To prevent the second slide 42 from moving relative to the first inclined surface 411 during the synchronous movement of the first slide 41 driving the second slide 42, this embodiment provides a first limiting block 45 on the first inclined surface 411 of the first slide 41. The first limiting block 45 has a first protruding ridge that protrudes from the first inclined surface 411. Correspondingly, two first limiting grooves 422 are arranged along the sliding direction on the bottom wall of the second slide 42, and the first protruding ridge can engage with either of the first limiting grooves 422. When the mold is closed, the first protruding ridge is embedded in the previous first limiting groove 422; when the mold is opened, after the second slide 42 moves a second preset distance on the first inclined surface 411, the first protruding ridge is embedded in the next first limiting groove 422.
[0049] See Figure 9 and Figure 10 The third demolding mechanism 5 includes a first slide 51, a second slide 52, a first drive 53, a second drive 54 and a third drive 55.
[0050] The first sliding member 51 is disposed on the moving template 21. The upper part of the first driving member 53 is connected to the fixed template 13. The lower part of the first driving member 53 is inclinedly inserted into the first sliding member 51. The first driving member 53 can drive the first sliding member 51 to move along the vertical mold opening direction, that is, to move along the horizontal direction.
[0051] The upper part of the first sliding member 51 is provided with a second inclined surface 511, which extends upward and outward in a horizontal direction. The second sliding member 52 is disposed on the second inclined surface 511. The upper parts of the second driving member 54 and the third driving member 55 are both connected to the fixed template 13. The lower part of the second driving member 54 is inserted into the second sliding member 52. The third driving member 55 is disposed on the inward side of the second driving member 54, and its lower part is adjacent to the inclined wall of the second sliding member 52.
[0052] The first driving member 53 is provided with a second straight portion 531 and a third inclined portion 532. The second straight portion 531 is located on the end of the third inclined portion 532 near the fixed template 13. The second straight portion 531 extends a predetermined length along the mold opening direction, and the third inclined portion 532 extends outward and downward at an angle along the mold opening direction. The first sliding member 51 has a third inclined hole 512. When the mold is closed, both the second straight portion 531 and the third inclined portion 532 are inserted into the third inclined hole 512, and there is a second safety distance between the hole wall of the third inclined hole 512 and the second straight portion 531.
[0053] The second driving member 54 is provided with a fourth inclined portion 541, which extends downward and outward along the mold opening direction. The second sliding member 52 has a fourth inclined hole, and the fourth inclined portion 541 is inserted into the fourth inclined hole and abuts against the outer side wall of the fourth inclined hole.
[0054] When the mold is opened, the second driving member 54 first drives the second sliding member 52 to move outward a third preset distance on the second inclined surface 511; then, the first driving member 53 drives the first sliding member 51 to move horizontally outward, thereby driving the second sliding member 52 to move synchronously; when the mold is closed, the third driving member 55 can drive the second sliding member 52 to move inward at an angle a fourth preset distance on the second inclined surface 511 to ensure that the second sliding member 52 moves back into place.
[0055] The first sliding member 51 is provided with a second limiting member 56, and the second limiting member 56 is provided with a second protruding ridge, which protrudes from the second inclined surface 511. The second sliding member 52 is provided with two second limiting grooves 521 arranged along its moving direction, and the second protruding ridge can engage with either of the second limiting grooves 521. When the mold is closed, the second protruding ridge is embedded in the upper second limiting groove 521; when the mold is opened, the second protruding ridge is embedded in the lower second limiting groove 521.
[0056] In summary, through the above-described configuration, during mold opening, the first inclined ejector 33 drives the second slider 32 to move via the first slider 31. During this period, under the elastic force of the first elastic element 343, the ejector block 341 pushes the product 10 towards the fixed mold 1, temporarily fixing the product 10. As the second slider 32 continues to move, one side wall of the flange portion 1012 at the hole of the product 10 can first separate from the second slider 32, achieving the first demolding. Then, the second slider 32 drives the ejector block 341 to move together via the first connecting element 342, causing the other side wall of the flange portion 1012 at the hole of the product 10 to separate from the ejector block 341, achieving the second demolding. This embodiment adopts a two-stage demolding method for the flange portion 1012 of the hole wall, which helps to avoid damage to the surface of the product 10 and improve the quality of the product 10. This invention also has the advantages of simple structure and convenient operation.
