Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a demolding mold with a diving port. Background Technology

[0002] Injection molds are common tools used in the manufacture of plastic products and are widely used in the production of plastic products. In existing injection molds, the parting surface of the product is usually located between the front mold core and the rear mold core, and the sprue is usually a large sprue structure that enters through the side. After the product is demolded, the sprue edge on the product needs to be manually smoothed, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies that require manual trimming of the sprue edges, and to provide a demolding mold with a sprue that eliminates the need for manual trimming of the sprue, thereby improving work efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A demolding mold with a submersible gate is provided, comprising a front mold, a rear mold, a front mold core, a rear mold core, a cavity, a main runner, a submersible gate, a core, and a push-pull mechanism. The front mold core is installed at the bottom of the front mold, and the rear mold core is installed at the top of the rear mold. The main runner passes through the front mold and the front mold core. The cavity is disposed on the side of the rear mold core, and the core is inserted into the cavity. The submersible gate passes through the rear mold core, with one end connected to the main runner and the other end connected to the cavity. The push-pull mechanism is installed on the side of the rear mold and is fixedly connected to the core. The rear mold is provided with an ejector mechanism for ejecting the submersible gate. An ejector channel is provided through the rear mold core and communicates with the submersible gate. The output end of the ejector mechanism is slidably installed in the ejector channel and located below the submersible gate.

[0006] This utility model discloses a demolding mold with a submersible gate. After the mold is closed, the injection material is injected into the submersible gate through the main runner, the front mold, and the front mold core. The injection material is then injected into the cavity located on the side of the rear mold core through the submersible gate. After the product cools and solidifies, the front mold and the rear mold are separated. The output end of the ejector mechanism located below the submersible gate passes through the ejector channel and ejects the submersible gate. The push-pull mechanism drives the core to move away from the core. Due to thermal expansion and contraction, the product is tightly wrapped around the core and moves with the core, detaching from the cavity and completing the mold opening process. By setting the cavity on the side of the rear mold core, a submersible gate can be set on the top of the product. The mold is opened after the submersible gate is ejected by the ejector mechanism, eliminating the need for manual gate trimming, saving manpower and improving work efficiency.

[0007] Furthermore, the push-pull mechanism includes a drive device and a slider assembly. The slider assembly is slidably connected to the rear mold. One end of the slider assembly is connected to the output end of the drive device, and the other end is connected to the end of the core away from the cavity. After the product cools and is formed, it is tightly wrapped around the core due to thermal expansion and contraction. The drive device drives the core to move away from the cavity, and the core pulls the product wrapped around the core to detach from the cavity.

[0008] Furthermore, the slider assembly includes a slider and a push plate. The end of the core away from the cavity is fixedly connected to the slider, the core passes through the push plate, and the slider and the push plate are slidably connected to the rear mold. The driving device drives the slider and the push plate to move away from the cavity, causing the core to detach from the cavity. Subsequently, the slider and the push plate move in a direction away from each other, and the core gradually detaches from the push plate. The product tightly wrapped on the core is blocked by the push plate as the slider moves. As the distance between the slider and the push plate gradually increases, the product gradually detaches from the core and falls naturally under the force of the push plate, thus demolding the product.

[0009] Furthermore, a first guide post perpendicular to the push plate is fixedly installed on the push plate, and a first guide hole that mates with the first guide post is provided in the slider. The first guide post is inserted into the first guide hole and slidably connected to the first guide hole. The first guide post and the first guide hole work together to guide the push plate and the slider, improving the stability of their relative movement.

[0010] Furthermore, it also includes a hook, a limiting block, and a guide structure for guiding the movement direction of the limiting block. The hook is connected to the slider. The bottom of the push plate is provided with a mounting groove extending into the push plate. The limiting block is slidably connected to the mounting groove. The hook is fixedly connected to the slider. The hook is provided with a limiting groove. The side of the limiting block near the cavity abuts against the limiting groove. The guide structure is disposed on the top of the rear mold. The guide structure contacts the limiting block. The top of the rear mold is provided with a stop block. The bottom of the slider is provided with a clearance groove that cooperates with the stop block. When the drive device drives the slider to move away from the cavity, the hook moves with the slider. The limiting groove of the hook pushes the limiting block to move away from the cavity, thereby driving the push plate to move with the slider. After the product leaves the cavity, the drive device continues to drive the slider to move. Under the action of the guide structure, the limiting block gradually retracts into the mounting groove and disengages from the hook. The hook no longer pulls the push plate, and the stop block prevents the push plate from moving further. The slider separates from the push plate. While blocking the push plate, the stop block also guides the slider by cooperating with the clearance groove.

[0011] Furthermore, the guiding structure is a guide groove, the top of the rear mold is provided with a sliding groove, the hook is slidably installed in the sliding groove, the top of the side wall of the sliding groove is provided with a guide groove, the bottom of the limiting block contacts the bottom of the guide groove, and the end of the guide groove away from the cavity is provided with a guide slope, the distance between the guide slope and the bottom of the push plate gradually decreases in the direction away from the cavity. When the hook slides in the sliding groove, it drives the limiting block to move. After the limiting block contacts the guide slope of the guide groove, the limiting block moves in the direction away from the cavity while gradually moving deeper into the mounting groove along the guide slope until the limiting block and the hook disengage, the stop block blocks the push plate from moving, and the slider separates from the push plate.

[0012] Furthermore, it also includes a first elastic element, one end of which is connected to the limiting block, and the other end of which is connected to the inner wall of the mounting groove. During mold closing, the driving device drives the slider to move towards the cavity. After the slider contacts the push plate, it pushes the push plate towards the cavity. The horizontal relative position of the limiting block and the guide slope changes, and a gap appears between the limiting block and the guide slope. Under the action of the elastic force of the first elastic element, the limiting block gradually extends out of the mounting groove and maintains contact with the guide slope. As the push plate gradually approaches the cavity, the limiting block gradually disengages from the guide slope and contacts the bottom of the guide groove.

[0013] Furthermore, the driving device includes a hydraulic cylinder and a hydraulic cylinder frame. The hydraulic cylinder frame is fixedly mounted on the rear mold, and the hydraulic cylinder is fixedly mounted on the hydraulic cylinder frame. The piston rod of the hydraulic cylinder is fixedly connected to the slider assembly. The driving device drives the piston rod to extend or retract, causing the slider assembly to move towards or away from the cavity, performing mold closing or demolding operations.

[0014] Furthermore, the ejector mechanism includes an ejector plate, ejector pins, and a lifting device. The lifting device is connected to the ejector plate. Ejector channels are provided in the rear mold and the rear mold core. The ejector pins are fixedly installed on the top of the ejector plate and slidably installed in the ejector channels. When ejecting the submersible gate, the lifting device drives the ejector plate upwards, causing the ejector pins on the mounting base ejector plate to move upwards until the ejector pins push the submersible gate out from the top of the front mold core, preventing interference with the submersible gate during product demolding.

[0015] Furthermore, the ejector mechanism also includes a second elastic element, which is connected between the ejector plate and the inner wall of the rear mold. When the ejector plate moves upward, the second elastic element is stretched. After the ejector plate drives the ejector pin to push out the submersible gate, the tension of the second elastic element drives the ejector plate to reset.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model discloses a demolding mold with a diving gate: 1. By setting the cavity on the side of the rear mold core, a diving gate can be set on the top of the product. After the diving gate is ejected by the ejector mechanism, the mold is opened without the need for manual cutting of the gate, saving manpower and improving work efficiency; 2. When the driving device drives the slider to move away from the cavity, the core drives the product to leave the cavity. The guide slope guides the limiting block to retract into the mounting groove, so that the slider separates from the push plate. The product leaves the core under the action of the push plate, realizing automatic demolding of the product. Attached Figure Description

[0027] Example 1

[0028] like Figures 1 to 6 The first embodiment of the demolding mold with a diving gate of the present invention is shown, including a front mold 1, a rear mold 2, a front mold core 3, a rear mold core 4, a cavity 42, a main runner 13, a diving gate 41, a core 5, and a push-pull mechanism 6. The front mold core 3 is installed at the bottom of the front mold 1, and the rear mold core 4 is installed at the top of the rear mold 2. The main runner 13 passes through the front mold 1 and the front mold core 3. The cavity 42 is located on the side of the rear mold core 4. The core 5 is inserted into the cavity 42. The diving gate 41 passes through the rear mold core 4. One end of the diving gate 41 is connected to the main runner 13, and the other end is connected to the cavity 42. The push-pull mechanism 6 is installed on the side of the rear mold 2 and is fixedly connected to the core 5. The rear mold 2 is provided with an ejector pin mechanism 7 for ejecting the diving gate 41. An ejector pin channel is provided through the rear mold core 4 and is connected to the diving gate 41. The output end of the ejector pin mechanism 7 is slidably installed in the ejector pin channel and is located below the diving gate 41. In this embodiment, the cavity 42 is disposed on the two sides of the rear mold core 4.

[0029] This utility model discloses a demolding mold with a diving gate. After the mold is closed, the injection material is injected through the main runner 13, through the front mold 1 and the front mold core 3, into the diving gate 41. The injection material is then injected through the diving gate 41 into the cavity 42 located on the side of the rear mold core 4. After the product cools and solidifies, the front mold 1 and the rear mold 2 are separated. Figure 2 As shown; the output end of the ejector mechanism 7 located below the submersible gate 41 passes through the ejector channel and pushes the submersible gate 41 out, as... Figure 4As shown; the push-pull mechanism 6 drives the core 5 to move away from the core 5. Due to thermal expansion and contraction, the product is tightly wrapped around the core 5 and moves together with the core 5, separating from the cavity 42, completing the first mold opening, as shown. Figure 5 As shown; by setting the cavity 42 on the side of the rear mold core 4, a submersible gate 41 can be set on the top of the product. After the submersible gate 41 is ejected by the ejector mechanism 7, the mold is opened without the need for manual cutting of the gate.

[0030] The push-pull mechanism 6 includes a drive unit 61 and a slider assembly 62. The slider assembly 62 is slidably connected to the rear mold 2. One end of the slider assembly 62 is connected to the output end of the drive unit 61, and the other end is connected to the end of the core 5 away from the cavity 42. After the product cools and is formed, it is tightly wrapped around the core 5 due to thermal expansion and contraction. The drive unit 61 drives the core 5 to move away from the cavity 42, and the core 5 causes the product wrapped around the core 5 to detach from the cavity 42.

[0031] The slider assembly 62 includes a slider 621 and a push plate 622. The end of the core 5 furthest from the cavity 42 is fixedly connected to the slider 621. The core 5 passes through the push plate 622. The slider 621 and push plate 622 are slidably connected to the rear mold 2. The driving device 61 drives the slider 621 and push plate 622 to move away from the cavity 42, causing the core 5 to detach from the cavity 42. Subsequently, the slider 621 and push plate 622 move away from each other, and the core 5 gradually detaches from the push plate 622. The product tightly wrapped around the core 5 is blocked by the push plate 622 as the slider 621 moves. As the distance between the slider 621 and the push plate 622 gradually increases, the product gradually detaches from the core 5 and falls naturally under the force of the push plate 622, thus demolding the product and completing the second mold opening. Figure 6 As shown.

[0032] In this embodiment, the slider 621 includes a slider body 6212 and a core plate 6213. One end of the slider body 6212 is fixedly connected to the output end of the drive device 61, and the other end is fixedly connected to the core plate 6213. The core 5 is fixedly installed on the core plate 6213.

[0033] A first guide post 626 perpendicular to the push plate 622 is fixedly installed on the push plate 622. A first guide hole that mates with the first guide post 626 is provided in the slider 621. The first guide post 626 is inserted into the first guide hole and slidably connected to the first guide hole. The first guide post 626 and the first guide hole cooperate to guide the push plate 622 and the slider 621, thereby improving the stability of their relative movement.

[0034] The front mold 1 includes a panel 11 and a front template 12. The rear mold 2 includes a base plate 23, a rear template 21, and square iron 22. The front template 12 is fixed to the bottom of the panel 11, the square iron 22 is fixed to the top of the base plate 23, and the rear template 21 is fixed to the top of the square iron 22. There are two square irons 22 that are parallel to each other. The ejector mechanism 7 is installed on the base plate 23 and is located between the two square irons 22. The output end of the ejector mechanism 7 passes through the rear template 21. The bottom of the front template 12 is provided with four second guide posts 121, and the top of the rear template 21 is provided with four second guide holes 214 that cooperate with the second guide posts 121. When the mold is closed, the second guide posts 121 play a positioning role for the front template 12, so as to achieve precise mold closing and facilitate installation.

[0035] The working principle of the demolding mold with a diving gate in this embodiment is as follows: The driving device 61 drives the slider assembly 62 to move towards the cavity 42 until the core 5 is inserted into the cavity 42, aligning the second guide post 121 of the front template 12 with the second guide hole 214 of the rear template 21, and merging the front template 12 and the rear template 21 to complete the mold closing; the injection material is injected into the diving gate 41 through the main runner 13, through the panel 11, the front template 12 and the front mold core 3, and the injection material is injected into the cavity 42 located on the side of the rear mold core 4 through the diving gate 41. After the product cools and is formed, the front mold 1 and the rear mold 2 are separated, and the top located below the diving gate 41... The output end of the needle mechanism 7 passes through the ejector pin channel and pushes out the submersible gate 41. The drive device 61 drives the slider 621 and the push plate 622 to move away from the cavity 42, causing the core 5 to detach from the cavity 42 and completing the first mold opening. Subsequently, the slider 621 and the push plate 622 move away from each other, and the core 5 gradually detaches from the push plate 622. The product tightly wrapped on the core 5 is blocked by the push plate 622 when the slider 621 moves. As the distance between the slider 621 and the push plate 622 gradually increases, the product gradually detaches from the core 5 and falls naturally under the force of the push plate 622, completing the second mold opening and realizing the automatic demolding of the product.

[0036] Example 2

[0037] This embodiment is the second embodiment of the demolding mold with a diving port of this utility model. This embodiment is similar to the first embodiment, except that, as Figure 1 As shown, it also includes a hook 623, a limiting block 624, and a guide structure for guiding the movement direction of the limiting block 624. The hook 623 is connected to the slider 621. The bottom of the push plate 622 is provided with a mounting groove extending into the push plate 622. The limiting block 624 is slidably connected to the mounting groove. The hook 623 is fixedly connected to the slider 621. The hook 623 is provided with a limiting groove. The side of the limiting block 624 near the cavity 42 abuts against the limiting groove. The guide structure is set on the top of the rear mold 2. The guide structure contacts the limiting block 624, such as... Figure 3As shown, the top of the rear mold 2 is provided with a stop block 213, and the bottom of the slider 621 is provided with a clearance groove 6211 that cooperates with the stop block 213. When the driving device 61 drives the slider 621 to move away from the cavity 42, the hook 623 moves with the slider 621. The limiting groove of the hook 623 pushes the limiting block 624 to move away from the cavity 42, thereby driving the push plate 622 to move with the slider 621. After the product leaves the cavity 42, the driving device 61 continues to drive the slider 621 to move. Under the action of the guide structure, the limiting block 624 gradually retracts into the mounting groove and disengages from the hook 623. The stop block 213 blocks the push plate 622 from moving further, and the slider 621 separates from the push plate 622. Figure 6 As shown, the stop block 213 not only blocks the push plate 622, but also guides the slider 621 by cooperating with the clearance groove 6211.

[0038] The guiding structure is a guide groove 212. The top of the rear mold 2 is provided with a slide groove 211. A pull hook 623 is slidably installed in the slide groove 211. The top of the side wall of the slide groove 211 is provided with a guide groove 212. The bottom of the limiting block 624 contacts the bottom of the guide groove 212. The end of the guide groove 212 away from the cavity 42 is provided with a guide slope, such as... Figure 5 and Figure 6 As shown. When the hook 623 slides in the slide groove 211, it drives the limiting block 624 to move. After the limiting block 624 contacts the guide slope of the guide groove 212, the limiting block 624 moves away from the cavity 42 and gradually moves into the depth of the mounting groove along the guide slope until the limiting block 624 and the hook 623 disengage. The stop block 213 blocks the push plate 622 from moving further, and the slider 621 separates from the push plate 622.

[0039] like Figure 6 As shown, it also includes a first elastic element 625, one end of which is connected to the limiting block 624, and the other end is connected to the inner wall of the mounting groove. During mold closing, the driving device 61 drives the slider 621 to move towards the cavity 42. After the slider 621 contacts the push plate 622, it pushes the push plate 622 towards the cavity 42. The horizontal relative position of the limiting block 624 and the guide slope changes, creating a gap between the limiting block 624 and the guide slope. Under the elastic force of the first elastic element 625, the limiting block 624 gradually extends out of the mounting groove and maintains contact with the guide slope. As the push plate 622 gradually approaches the cavity 42, the limiting block 624 gradually disengages from the guide slope and contacts the bottom of the guide groove 212. In this embodiment, the first elastic element 625 is a spring, and the limiting block 624 has a spring groove. The first elastic element 625 is connected to the bottom of the spring groove.

[0040] The drive unit 61 includes a hydraulic cylinder 611 and a hydraulic cylinder frame 612. The hydraulic cylinder frame 612 is fixedly mounted on the rear mold 2, and the hydraulic cylinder 611 is fixedly mounted on the hydraulic cylinder frame 612. The piston rod of the hydraulic cylinder 611 is fixedly connected to the slider assembly 62. The drive unit 61 drives the piston rod to extend or retract, thereby moving the slider assembly 62 toward or away from the cavity 42 to perform mold closing or demolding operations.

[0041] The working principle of the demolding mold with a diving opening in this embodiment is as follows: When the hydraulic cylinder 611 drives the slider 621 to move away from the cavity 42, the slider 621 drives the hook 623 to slide in the groove 211. The limiting groove of the hook 623 pushes the limiting block 624 to move away from the cavity 42, thereby driving the push plate 622 to move together with the slider 621. After the product leaves the cavity 42, the hydraulic cylinder 611 continues to drive the slider 621 to move. After the limiting block 624 contacts the guide slope of the guide groove 212, it... Under the elastic force of the first elastic element 625, the product moves gradually into the depth of the mounting groove along the guide slope until the limiting block 624 and the hook 623 disengage. The stop block 213 prevents the push plate 622 from moving further, and the slider 621 and the push plate 622 gradually separate. The core 5 gradually detaches from the push plate 622. The product wrapped tightly on the core 5 is blocked by the push plate 622 when the slider 621 moves. As the distance between the slider 621 and the push plate 622 gradually increases, the product gradually detaches from the core 5 and falls naturally under the force of the push plate 622.

[0042] Example 3

[0043] This embodiment is the third embodiment of the demolding mold with a diving port of this utility model. This embodiment is similar to the first embodiment, except that, as Figure 1 and Figure 6 As shown, the ejector mechanism 7 includes an ejector plate 71, ejector pins 72, and a lifting device 74. The lifting device 74 is connected to the ejector plate 71. Ejector channels are provided in the rear mold 2 and the rear mold core 4. The ejector pins 72 are fixedly installed on the top of the ejector plate 71 and slidably installed in the ejector channels. When ejecting the submersible gate 41, the lifting device 74 drives the ejector plate 71 to move upward, which in turn drives the ejector pins 72 on the mounting base ejector plate 71 to move upward until the ejector pins 72 eject the submersible gate 41 from the top of the front mold core 3, preventing interference with the submersible gate 41 when the product is demolded.

[0044] The ejector mechanism 7 also includes a second elastic element 73, which is connected between the ejector plate 71 and the inner wall of the rear mold 2. Specifically, the second elastic element 73 is connected between the ejector plate 71 and the lower surface of the rear mold plate 21. When the ejector plate 71 moves upward, the second elastic element 73 is compressed. After the ejector plate 71 drives the ejector pin 72 to push out the submersible gate 41, the elastic force of the second elastic element 73 drives the ejector plate 71 to return to its original position. In this embodiment, the second elastic element 73 is a spring.

[0045] The working principle of the demolding mold with a diving gate in this embodiment is as follows: When the diving gate 41 is ejected, the lifting device 74 drives the ejector plate 71 to move upward. While compressing the second elastic element 73, it drives the ejector pin 72 on the mounting seat ejector plate 71 to move upward until the ejector pin 72 ejects the diving gate 41 from the top of the front mold core 3, stops driving the ejector plate 71, and the elastic force of the second elastic element 73 in the compressed state pushes the ejector plate 71 to reset.

[0046] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
