Description

Technical Field

[0001] This utility model relates to the field of injection molding demolding technology, specifically to a mold that facilitates demolding. Background Technology

[0002] In injection molding, for plastic parts with complex structures such as side recesses, side holes, or undercuts, a slider core-pulling mechanism is usually required to release the undercuts from the product. In the current mainstream front mold slider demolding solutions, the movement of the slider is mostly driven by the opening and closing action of the moving mold and the fixed mold.

[0003] Currently, in a novel injection mold disclosed in an existing patent (application number: 202422418484.3) that allows for demolding of a product with an inverted inner side, the upper mold (hereinafter referred to as the moving mold) moves upward along the mold opening direction during use. The upper mold drives the mutually fixed inclined guide pillars (hereinafter referred to as the guide parts) to move upward simultaneously. Since the inclined part of the inclined guide pillar is fitted with the extension plate, and the extension plate only slides horizontally along the step, the inclined guide pillar guides the extension plate and the slider to slide horizontally towards the opening on the outside of the step during the upward movement. This allows the slider to drive the pull block to detach from the product's inverted side and complete the demolding operation. Furthermore, the upper mold needs to have sufficient mold opening movement distance to ensure complete detachment from the product. However, since the upper mold drives the slider to move, the slider's movement stroke becomes larger, resulting in a correspondingly larger size required for the inclined guide pillars used to guide the slider's movement. This enlarges the overall volume of the mold frame and occupies more space. Utility Model Content

[0004] In view of this, the present invention provides a mold that is easy to demold, aiming to solve the technical problem that existing molds directly drive the slider to move, resulting in a larger slider travel, which in turn requires a larger guide part to guide the slider to slide, thus increasing the overall volume of the mold frame and occupying more space.

[0005] To solve the above-mentioned technical problems, this utility model provides a mold that facilitates demolding, including a top plate, a fixed mold, and a moving mold. The fixed mold is located below the top plate, and the moving mold is located below the fixed mold and can move up and down in a vertical direction. A molding cavity for molding a product is provided between the fixed mold and the moving mold. A demolding mechanism is provided inside the fixed mold. The demolding mechanism includes an inclined guide, a slider, and a pushing component. The inclined guide is inclined from top to bottom towards the product in the molding cavity. The slider slides with the inclined guide. The side of the slider facing away from the inclined guide is an inclined surface. The inclined surface is inclined from top to bottom towards the product. A recess is formed on the inclined surface, penetrating the bottom surface of the inclined surface. The recess is used to form a protrusion of the product. The pushing component is located between the top plate and the slider. When the moving mold disengages from the fixed mold, the moving mold moves the product in the molding cavity downward, and at the same time, the pushing component pushes the slider to slide along the inclined guide, causing the recess to disengage from the protrusion.

[0006] Furthermore, the pushing component includes an elastic element. When the moving mold and the fixed mold are closed, the lower end of the slider abuts against the upper part of the moving mold. The elastic element is disposed between the slider and the top plate. The elastic element is in a compressed and stored state. When the moving mold separates from the fixed mold and moves downward, the elastic element rebounds to push the slider to slide along the inclined guide portion.

[0007] Furthermore, the pushing assembly also includes a push rod, which is capable of sliding vertically relative to the fixed mold. The upper end of the push rod abuts against the lower end of the elastic element, and the lower end of the push rod abuts against the upper end of the slider.

[0008] Furthermore, the fixed mold has a guide groove that penetrates its opposite surface, the inclined guide part is disposed in the guide groove, and the guide groove is also used to accommodate the slider that slides along the inclined guide part.

[0009] Furthermore, the upper end of the push rod is provided with an annular stop block, the diameter of which is greater than the outer diameter of the push rod and smaller than the outer diameter of the elastic element; the annular stop block is located between the fixed mold and the top plate and is used to connect and fix with the elastic element.

[0010] Furthermore, a guide post is provided on one inner side wall of the guide groove, and an inclined surface is provided on the side of the guide post facing the product. The inclined guide part includes a guide rail, which is fixed on the inclined surface. A sliding groove adapted to the guide rail is provided on the slider, and the slider slides in cooperation with the guide rail through the sliding groove.

[0011] Furthermore, a limit component is provided on one side of the guide groove, which is used to limit the movement stroke of the slider.

[0012] Furthermore, the limiting component includes a limiting post, and the slider is provided with a limiting notch. When the slider slides to a preset position, the limiting post abuts against the side wall of the limiting notch.

[0013] Furthermore, the limiting post is detachably connected to the fixed mold.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the demolding mechanism of this utility model is in use, in the mold-closed state when the moving mold is raised and the fixed mold is closed, the slider is located in a preset position. The recessed part on the inclined surface of the slider corresponds to the position of the protrusion of the product in the molding cavity. That is, the recessed part is part of the molding cavity. During product molding, the protrusion of the product (the undercut structure of the product) is formed by the recessed part. When the mold opening operation is performed, the moving mold is lifted and lowered by the driving mechanism of the injection molding equipment to separate from the fixed mold. At the same time, the product in the molding cavity moves down synchronously. Simultaneously, the pushing component pushes the slider to slide along the inclined guide. Since the inclined guide is inclined from top to bottom in the direction away from the molding cavity, the slider will move synchronously away from the product when it slides. When the slider slides down in an inclined direction, the recessed part on the slider and the protrusion of the product are separated during the mold opening process of the moving mold. The slider does not need to follow the large stroke of the moving mold, avoiding the moving mold from driving the slider to move and making the slider's stroke larger. This avoids the need for a larger size of the guide part used to guide the slider to slide, thereby reducing the overall volume of the mold frame and making the mold structure more compact.

[0021] Please refer to Figures 1-9 This utility model provides a mold that is easy to demold.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The mold includes a top plate 100, a fixed mold 300, and a moving mold 200. The fixed mold 300 is fixedly mounted on the lower part of the top plate 100 by bolts. The moving mold 200 is located below the fixed mold 300 and can be raised and lowered vertically. The moving mold 200 is driven by the drive mechanism in the overall injection molding equipment, enabling it to rise and fall to achieve mold opening and closing. A molding cavity 201 for molding the product 400 is provided between the fixed mold 300 and the moving mold 200. When the moving mold 200 and the fixed mold 300 are closed, the molding cavity 201 between them is closed, and injection molding can then be performed to mold the product 400 through the molding cavity 201. A demolding mechanism is provided inside the fixed mold 300, located inside the fixed mold 300 and adjacent to the molding cavity 201. The demolding mechanism includes an inclined guide 500, a slider 600, and a pushing assembly 700.

[0023] Specifically, the inclined guide portion 500 is inclined from top to bottom towards the product 400 away from the molding cavity 201. The slider 600 is located between the inclined guide portion 500 and the molding cavity 201. One side of the slider 600 is slidably engaged with the inclined guide portion 500 and can slide along the inclined guide portion 500. The side of the slider 600 facing away from the inclined guide portion 500 is an inclined surface, which faces the molding cavity 201 and is inclined from top to bottom towards the product 400. A recessed portion 601 is provided on the upper part, which penetrates the bottom surface of the inclined surface. The recessed portion 601 is used to form the protrusion 401 of the product 400. When the mold is closed, the slider 600 is located in a preset position. At this time, the recessed portion 601 corresponds to the position of the protrusion 401 of the product 400 in the molding cavity 201, so that the recessed portion 601 and the molding cavity 201 cooperate to form the product 400. At this time, the protrusion 401 of the product 400 is formed in the recessed portion 601.

[0024] The pushing component 700 is disposed between the top plate 100 and the slider 600. When the product 400 is formed and the moving mold 200 separates from the fixed mold 300, the moving mold 200 drives the product 400 in the forming cavity 201 to move downward, so that the product 400 remains in the forming cavity 201 of the moving mold 200. At the same time as the moving mold 200 descends and opens the mold, the pushing component 700 pushes the slider 600 to slide along the inclined guide 500. Due to the inclined design of the inclined guide 500, the slider 600 slides from top to bottom away from the product 400. During the sliding process, the slider 600 moves away from the product 400. When the slider 600 slides down at an incline, its inclined surface separates from the inclined surface of the protrusion 401 of the product 400 during the mold opening process of the moving mold 200, thereby gradually separating the recessed part 601 from the protrusion 401 of the product 400, thus completing the undercut separation operation. This positional layout allows the stroke of slider 600 to be controlled solely by push assembly 700. Regardless of the size of the moving mold 200's travel, the stroke of slider 600 is always controlled by the inclined guide 500 and push assembly 700, eliminating the need to follow the large travel of the moving mold 200. This avoids the need for a correspondingly larger guide portion to guide the slider 600's movement, thus significantly reducing the internal space occupied by the fixed mold 300 and making the mold structure more compact.

[0025] Reference Figure 4 , Figure 5 and Figure 6 The pushing component 700 includes an elastic element 701, which is located between the slider 600 and the top plate 100. When the moving mold 200 and the fixed mold 300 are closed, the lower end of the slider 600 abuts against the upper part of the moving mold 200. Due to the abutment and obstruction of the moving mold 200, the elastic element 701 is in a compressed and stored state. When the product 400 is formed and the moving mold 200 and the fixed mold 300 separate and move down to open the mold, the elastic element 701 has a rebound space. The elastic element 701 gradually rebounds to push the slider 600 to slide along the inclined guide 500, so that the recessed part 601 of the slider 600 disengages from the protrusion 401 of the product 400 to complete the demolding. Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The push assembly 700 also includes a push rod 702, which can slide vertically relative to the fixed mold 300. The upper end of the push rod 702 abuts against the lower end of the elastic element 701, and the lower end of the push rod 702 abuts against the upper end of the slider 600.

[0026] In other embodiments, the actuating component 700 may be an automatically controlled actuator commonly used in the prior art, such as an electrically telescopic push rod, which is not limited here.

[0027] Reference Figure 3 , Figure 4, Figure 5 and Figure 6 The fixed mold 300 has a guide groove 301 that penetrates its opposite surface. The guide groove 301 extends vertically and corresponds to the side of the product 400. The inclined guide part 500 is disposed in the guide groove 301. The guide groove 301 is also used to accommodate the slider 600 that slides along the inclined guide part 500.

[0028] Specifically, a through groove 302 is vertically formed on the inner wall of the guide groove 301, and a receiving groove 101 is formed on the lower wall of the top plate 100 corresponding to the through groove 302. The receiving groove 101 extends vertically, and the through groove 302 is coaxial with the receiving groove 101, with the position of the through groove 302 opposite to the upper surface of the slider 600. The elastic element 701 is disposed in the receiving groove 101, and the ejector rod 702 passes through the through groove 302, with its axis coinciding with the axis of the through groove 302, allowing the ejector rod 702 to slide vertically relative to the fixed mold 300. The upper end of the ejector rod 702 extends into the receiving groove 101 and abuts against the lower end of the elastic element 701. The abutment position is at the elastic element. In the central area of ​​701, the lower end of the ejector pin 702 extends out of the through slot 302 and abuts against the corresponding position on the upper end of the slider 600. The length of the ejector pin 702 ensures that it can move upward with the slider 600 to compress the elastic element 701 when the mold is closed, and can push the slider 600 downward with the rebound of the elastic element 701 when the mold is opened. The position of the ejector pin 702 allows the elastic force of the elastic element 701 to be accurately transmitted to the slider 600 through the ejector pin 702. When the moving mold 200 descends to open the mold, the elastic element 701 rebounds and pushes the ejector pin 702 to descend vertically. The vertical descent of the ejector pin 702 applies a vertical downward thrust to the slider 600, causing the slider 600 to slide down along the inclined guide portion 500.

[0029] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 An annular stop 703 is coaxially fixed to the upper end of the ejector rod 702. The annular stop 703 is inserted through the receiving groove 101 and abuts against the lower end of the elastic member 701. The diameter of the annular stop 703 is larger than the outer diameter of the ejector rod 702, so that the annular stop 703 cannot pass through the through groove 302 and can only move vertically within the receiving groove 101, preventing the ejector rod 702 from disengaging from the through groove 302 when it descends. The diameter of the annular stop 703 is smaller than the outer diameter of the elastic member 701, and the annular stop 703 is located between the fixed mold 300 and the top plate 100. The upper end of the annular stop 703 is connected and fixed to the elastic member 701, so that the annular stop 703 can always be connected to the elastic member 701.

[0030] When the moving mold 200 rises to close the mold, the moving mold 200 pushes the slider 600 to rise along the inclined guide 500. At this time, the rise of the slider 600 will push the ejector rod 702 to rise. The ejector rod 702 applies upward pressure to the elastic member 701 through the annular stop 703, thereby compressing the elastic member 701 in the receiving groove 101.

[0031] Specifically, the elastic element 701 is a spring, which is vertically arranged in the receiving groove 101. The upper end of the spring is fixedly connected to the inner wall of the receiving groove 101, and the lower end of the spring is fixedly connected to the lower end of the annular stop 703. The spring is coaxial with the receiving groove 101 to prevent the spring from shifting laterally. When the mold is closed, the spring is compressed, and when the mold is opened, the spring rebounds. The force that pushes the slider 600 is applied through the spring.

[0032] Reference Figure 4 and Figure 5 A guide post 501 is also provided on one inner side wall of the guide groove 301. The guide post 501 is fixedly installed vertically on the side wall of the guide groove 301 away from the molding cavity 201, and the upper end face of the guide post 501 matches the upper opening of the guide groove 301. The guide post 501 has an inclined surface on the side facing the molding cavity 201. The inclined surface slopes from the upper end to the lower end of the guide post 501 from top to bottom in a direction away from the molding cavity 201. The inclined guide part 500 includes a guide rail 502. The guide rail 502 is fixed on the inclined surface along the inclined direction and fully fits the inclined surface. The slider 600 has a groove on the side facing the guide post 501 that is adapted to the guide rail 502. The slider 600 is sleeved on the guide rail 502 through the groove. The inner side wall of the groove is in close contact with the surface of the guide rail 502, ensuring that the slider 600 slides with the guide rail 502 through the groove. The inclined surface of the slider 600 facing away from the guide post 501 always faces the molding cavity 201.

[0033] Specifically, the cross-section of the guide rail 502 is a T-shaped structure, and the cross-section of the slide groove is a T-shaped slide groove that matches the guide rail 502, so that the slider 600 always cooperates with the guide rail 502, ensuring that the slider 600 cannot disengage from the guide rail 502 in the vertical direction, but can only slide along the length direction of the guide rail 502.

[0034] Reference Figure 7 and Figure 8 A limiting component is provided on one side of the guide groove 301. The limiting component is used to limit the movement stroke of the slider 600. The position of the limiting component is preset according to the maximum demolding stroke of the slider 600. When the slider 600 slides along the guide rail 502 until the recess 601 is completely separated from the protrusion 401 of the product 400, the slider 600 just contacts the limiting component, preventing the slider 600 from continuing to slide down, thereby limiting the maximum stroke of the slider 600 and preventing the slider 600 from leaving the guide rail 502.

[0035] Reference Figure 7 and Figure 8 The limiting component includes a limiting post 800. A limiting groove 303 is vertically opened in the fixed mold 300 and adjacent to the guide groove 301. The limiting post 800 is placed in the limiting groove 303. The limiting post 800 is located on the side of the lowest end of the guide rail 502. The limiting post 800 extends vertically and has a rectangular column structure. A limiting notch 602 is vertically opened on the slider 600 and at the position facing the limiting post 800. When the slider 600 slides down the guide rail 502 at an angle, the limiting post 800 abuts against the side wall of the limiting notch 602 when the slider 600 slides to the preset position, so that the slider 600 is blocked by the limiting post 800 and cannot continue to move down.

[0036] Reference Figure 7 , Figure 8 and Figure 9 The limiting post 800 and the fixed mold 300 are detachably connected.

[0037] Specifically, a through hole is made vertically through the limiting post 800, and a threaded hole is made vertically on the upper inner wall of the limiting groove 303, with the threaded hole coaxially corresponding to the through hole of the limiting post 800. Then, the threaded locking part 801 is first passed through the through hole and then screwed into the threaded hole to lock the limiting post 800. By locking the limiting post 800, the limiting post 800 can be disassembled at will, so that the slider 600 can be removed without being limited, making it easy to replace different sliders 600.

[0038] In summary, the working principle of this utility model is as follows: During the mold closing stage, the moving mold 200 is driven to rise by the drive mechanism in the injection mold. At this time, the moving mold 200 pushes the slider 600 to rise, so that the slider 600 slides along the inclined direction of the guide rail 502 until the mold closing is completed. The moving mold 200 and the fixed mold 300 form a molding cavity 201. The recessed part 601 on the inclined surface of the slider 600 corresponds to the position of the protrusion 401 of the product 400 in the molding cavity 201. That is, the recessed part 601 is part of the molding cavity 201. When molding the product 400, the protrusion 401 of the product 400 is formed by the recessed part 601, so that the product 400 forms a complete plastic part with the protrusion 401.

[0039] During the mold opening stage, the moving mold 200 descends vertically and gradually separates from the fixed mold 300. The moving mold 200, through its adhesion to the product 400, descends synchronously. As the moving mold 200 descends, the spring in the receiving groove 101 releases its elastic potential energy, pushing the annular stop 703 downwards. The annular stop 703 pushes the ejector rod 702 downwards along the through groove 302. The ejector rod 702 transmits the spring force to the slider 600. Because the inclined guide 500 is inclined from top to bottom away from the molding cavity 301, the slider 600 slides synchronously towards... As the slider 600 moves away from the product 400 and tilts downwards, the recessed portion 601 on the slider 600 separates from the protruding portion 401 of the product 400 during the mold opening process of the moving mold 200, thus completing the demolding action. This eliminates the need for the slider 600 to follow the moving mold 200 in a large stroke, avoiding the moving mold 200 driving the slider 600 to move and thus increasing the stroke of the slider 600. This also avoids the need for a larger guide portion to guide the slider 600's sliding, thereby reducing the overall volume of the mold base and making the mold structure more compact.

[0040] When the slider 600 slides down to the preset position, the limiting post 800 abuts against the side wall of the limiting notch 602, preventing the slider 600 from moving further down and thus limiting its travel. The plastic part is only connected to the moving mold 200 through its main body. Finally, the product 400 is ejected from the molding cavity 201 by the ejection mechanism below the moving mold 200. The ejection mechanism is a common mechanism in the prior art and will not be described in detail here.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
