[0019] (III) Beneficial effects
[0020] The beneficial effects of the utility model are:
[0021] 1. The utility model is a core-pulling inclined ejector device for the release of an injection molded part of a head-up display cover plate of an automobile. By arranging a core-pulling assembly, an inclined ejector, an inclined ejector seat and a driving member, the driving member can drive the core-pulling assembly to move along the direction of the driving member. At the same time, the inclined ejector moves along the inclined supporting surface due to the movement of the core-pulling assembly. Since there is an angle between the extension direction of the inclined ejector and the moving direction of the core-pulling assembly, an inclined supporting surface is provided on the top of the inclined ejector seat. During the process of the core-pulling assembly descending along the direction of the driving member, the inclined ejector moves along the inclined supporting surface of the inclined ejector seat until the core-pulling assembly and the inclined ejector move to the first demolding station, so that the top of the core-pulling assembly matched with the first undercut is separated from the first undercut, and the top of the inclined ejector matched with the first undercut and the second undercut is separated from the second undercut, thereby realizing the first release. The driving member continues to drive the core pulling assembly and the inclined ejector assembly to move to the second demolding station, that is, continue to descend, so that the core pulling assembly and the inclined ejector assembly reach the second demolding station from the first demolding station, so that the top of the inclined ejector is disengaged from the first undercut, completing the second disengagement, thereby achieving the core pulling inclined ejector device to completely disengage the first undercut and the second undercut on the cover body, avoiding damage to the undercut of the head-up display cover, thereby improving the product qualification rate and reducing the product damage rate.
[0022] 2. The utility model is a core-pulling inclined ejector device for the release of the injection molded parts of the head-up display cover of an automobile. Since there are multiple second undercuts on the head-up display cover and the multiple second undercuts are parallel, multiple groups of inclined ejector assemblies are provided and correspond one-to-one with the multiple second undercuts, which can realize the injection molding of multiple second undercuts of the injection molded parts, and, during demolding, the multiple groups of inclined ejector assemblies can also move to the first demolding station at the same time, so that the multiple second undercuts can be separated from the multiple inclined ejectors, so as to complete the first release at the same time. By providing a T-shaped slide groove at the top of the inclined ejector seat, and providing a T-shaped slider that matches the T-shaped slide groove at the bottom of the inclined ejector, it can not only enable the inclined ejector to move on the inclined ejector seat, but also enable the inclined ejector to move along the inclined direction of the T-shaped slide groove to limit the moving trajectory of the inclined ejector.
[0023] 3. The utility model discloses a core-pulling and inclined ejector device for releasing the injection-molded parts of the automobile head-up display cover. A fixed seat is arranged below the core-pulling assembly, and the fixed seat is U-shaped. The side walls of the core-pulling assembly and the inner walls of the fixed seat are spaced apart from each other, thereby achieving the connection between the core-pulling assembly and the inclined ejector assembly from the first demolding station to the second demolding station. At the same time, it also avoids the driving member driving the core-pulling assembly and the inclined ejector assembly to move too long a distance. The fixed seat also limits the core-pulling assembly and the inclined ejector assembly when they move from the first demolding station to the second demolding station.
[0024] 4. The utility model discloses a core-pulling inclined top device for disengaging an injection-molded part of a head-up display cover of an automobile. The core-pulling mold and the core-pulling top plate are provided, and the inclined top passes through the core-pulling mold, and the inclined top seat is fixedly installed on the core-pulling top plate. The core-pulling mold can be driven down by a driving member, and the inclined top can only pass through the top of the core-pulling mold, so that the inclined top can move along the inclined supporting surface of the inclined top seat, and then the core-pulling mold can limit the inclined top, so that the inclined top moves in the direction away from the second undercut, thereby disengaging the core-pulling mold from the first undercut and disengaging the inclined top from the second undercut.
[0025] 5. The utility model is a core-pulling inclined ejector device for the release of the injection molded parts of the head-up display cover of an automobile. By setting a first limit block at the bottom of the core-pulling mold, it can abut the top of the core-pulling ejector plate when the core-pulling mold reaches the first demolding station, so that the core-pulling mold can no longer move independently, thereby preventing the inclined ejector from continuing to move along the inclined ejector seat when the core-pulling mold moves independently, thereby causing damage to the device.
[0026] 6. The utility model is a core-pulling inclined ejector device for disengaging an injection molded part of a head-up display cover of an automobile. By setting a second limit block, it can limit the core-pulling mold so that the core-pulling mold can only move along the direction of the driving member. By setting two second limit blocks, it can prevent the core-pulling mold from deflecting and offsetting, making the movement of the core-pulling mold more stable.
[0027] 7. The utility model is a core-pulling inclined ejector device for the release of the injection molded parts of the head-up display cover of an automobile. By setting a moving block, a first slot, a second slot and a long through hole, and placing the moving block in the second slot and the long through hole, when the core-pulling mold moves to the first demolding station, the moving block is clamped in the second slot and placed in the long through hole. When the core-pulling mold moves to the second demolding station, the moving block is clamped in the second slot and placed in the long through hole. When the core-pulling mold moves to the second demolding station, the first limiting block presses against the core-pulling top plate, so that the driving member drives the core-pulling mold and the core-pulling top plate to move simultaneously, and then the moving block squeezes the second slot and moves along the long through hole to engage with the first slot, so as to limit the second limiting block, thereby ensuring that the core-pulling mold and the core-pulling top plate can move simultaneously when moving from the first demolding station to the second demolding station, thereby realizing the inclined ejector disengagement from the first undercut. By setting the moving block to be a hexagon with two ends being triangles, and the first slot and the second slot also being triangles, it is possible to reduce friction when the moving block squeezes the first slot and the second slot, thereby preventing the second limit block from being unable to engage with the moving block, thereby preventing the core pulling mold from moving alone.

On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0039] Embodiment 1
[0040] like Figure 1-Figure 8 As shown, in a core-pulling and inclined ejector 31 device for disengaging an automobile head-up display cover injection molded part in this embodiment, the automobile head-up display cover injection molded part includes a cover body 1 and a first undercut 11 and a second undercut 12 located at the bottom of the cover body 1, and the core-pulling and inclined ejector 31 device includes a core-pulling assembly 2, an inclined ejector assembly 3 and a driving member 4.
[0041] Specifically, the top of the core pulling assembly 2 cooperates with the first undercut 11. The inclined ejector assembly 3 includes an inclined ejector 31 and an inclined ejector seat 32 fixedly installed inside the core pulling assembly 2. The extending direction of the inclined ejector 31 and the moving direction of the core pulling assembly 2 have an angle. The top of the inclined ejector seat 32 is provided with an inclined support surface for supporting the inclined ejector 31, and the inclined ejector 31 can be movably installed on the inclined ejector seat 32 along the inclined support surface. The top of the inclined ejector 31 passes through the top of the core pulling assembly 2 and cooperates with the first undercut 11 and the second undercut 12. The driving member 4 is used to drive the core pulling assembly 2 to move and then convert it into the movement of the inclined ejector 31 through the inclined support surface. The driving member 4 can simultaneously drive the core pulling assembly 2 and the inclined ejector assembly 3 to move to the first demolding station and the second demolding station successively, so as to separate the core pulling assembly 2 from the first undercut 11 and the inclined ejector 31 from the second undercut 12 at the first demolding station, and separate the inclined ejector 31 from the first undercut 11 at the second demolding station. By arranging the core pulling assembly 2, the inclined top 31, the inclined top seat 32 and the driving member 4, it is possible to realize that the driving member 4 can drive the core pulling assembly 2 to move along the direction of the driving member 4. At the same time, the inclined top 31 moves along the inclined supporting surface of the inclined top seat 32 due to the movement of the core pulling assembly 2. Since there is an angle between the extension direction of the inclined top 31 and the moving direction of the core pulling assembly 2, the top of the inclined top seat 32 is provided with an inclined supporting surface. In the process of the core pulling assembly 2 descending along the direction of the driving member 4, the inclined top 31 will move along the inclined supporting surface of the inclined top seat 32 until the core pulling assembly 2 and the inclined top 31 move to the first demolding station, so that the top of the core pulling assembly 2 matched with the first undercut 11 is separated from the first undercut 11, and the top of the inclined top 31 matched with the first undercut 11 and the second undercut 12 is separated from the second undercut 12, thereby realizing the first demolding. The core pulling assembly 2 and the inclined ejector assembly 3 are continuously driven by the driving member 4 to move to the second demolding station, that is, continue to descend, so that the core pulling assembly 2 and the inclined ejector assembly 3 reach the second demolding station from the first demolding station, so that the top of the inclined ejector 31 is separated from the first undercut 11, and the second demolding is completed, so that the core pulling inclined ejector 31 device completely separates the first undercut 11 and the second undercut 12 on the cover body 1, avoiding damage to the undercut of the head-up display cover, thereby improving the qualified rate of the product and reducing the damage rate of the product. Preferably, there are multiple second undercuts 12 and multiple second undercuts 12 are arranged in parallel, and the core pulling inclined ejector 31 device is provided with multiple groups of inclined ejector assemblies 3 corresponding to the multiple second undercuts 12, and the multiple groups of inclined ejector assemblies 3 are parallel to each other, which can realize the injection molding of multiple second undercuts 12 of the injection molded part, and, when demolding, the multiple groups of inclined ejector assemblies 3 can also move to the first demolding station at the same time, so that the multiple second undercuts 12 can be separated from the multiple inclined ejectors 31, so as to complete the first demolding at the same time. The driving member 4 drives the core pulling assembly 2 to rise and fall; when the driving member 4 drives the core pulling assembly 2 to rise, the bottom of the inclined top 31 moves upward along the inclined support surface. When the driving member 4 drives the core pulling assembly 2 to fall, the bottom of the inclined top 31 moves downward along the inclined support surface.
[0042] Furthermore, if Figure 2 As shown, a T-shaped slot 321 is provided at the top of the inclined top seat 32, and the bottom wall of the T-shaped slot 321 constitutes an inclined support surface. A T-shaped slider 311 matching the T-shaped slot 321 is provided at the bottom of the inclined top 31, and both the T-shaped slot 321 and the T-shaped slider 311 are inclined toward one side. The inclined top 31 is engaged with the inclined top seat 32 through the T-shaped slider 311 and the T-shaped slot 321, and the inclined top 31 can move obliquely along the T-shaped slot 321. By providing the T-shaped slot 321 and the T-shaped slider 311, it is realized that not only the inclined top 31 can move on the inclined top seat 32, but also the inclined top 31 can move along the inclined direction of the T-shaped slot 321, so as to limit the moving track of the inclined top 31.
[0043] Furthermore, if Figure 3 As shown, a fixed seat 5 is provided below the core pulling assembly 2 and the fixed seat 5 is U-shaped, with the U-shaped opening facing the core pulling assembly 2. There is a gap between the side walls of the core pulling assembly 2 and the inner walls of the two sides of the fixed seat 5, and the driving member 4 can drive the core pulling assembly 2 to move from the first demolding station to the second demolding station in the fixed seat 5 to receive the core pulling assembly 2, while also preventing the driving member 4 from driving the core pulling assembly 2 and the inclined ejector assembly 3 to move too long a distance, and the fixed seat 5 also limits the core pulling assembly 2 and the inclined ejector assembly 3 when they move from the first demolding station to the second demolding station.
[0044] Furthermore, the core pulling assembly 2 includes a core pulling mold 21 and a core pulling top plate 22 .
[0045] Specifically, the top of the core-pulling mold 21 cooperates with the first undercut 11, the core-pulling mold 21 is located above the core-pulling top plate 22 and there is a gap between the core-pulling mold 21 and the core-pulling top plate 22, the inclined top seat 32 is fixedly installed on the top wall of the core-pulling top plate 22, and the top of the inclined top 31 passes through the top of the core-pulling mold 21. The driving member 4 is a telescopic cylinder and the extended end of the driving member 4 passes through the fixed seat 5 and the core-pulling top plate 22 in sequence and is fixedly connected to the side wall of the core-pulling mold 21. The driving member 4 can retract to drive the core-pulling mold 21 to move to the first demolding station, the core-pulling mold 21 is separated from the first undercut 11, and the inclined top 31 moves along the inclined support surface with the movement of the core-pulling mold 21 and is separated from the second undercut 12. The driving member 4 can continue to retract and drive the core-pulling mold 21, the core-pulling top plate 22, the inclined top 31 and the inclined top seat 32 to move from the first demolding station to the second demolding station, so that the inclined top 31 is separated from the second undercut 12. By setting the core-pulling mold 21 and the core-pulling top plate 22, and the inclined top 31 passes through the core-pulling mold 21, and the inclined top seat 32 is fixedly installed on the core-pulling top plate 22, it can realize that the core-pulling mold 21 is driven down by the driving member 4, and the inclined top 31 can only pass through the top of the core-pulling mold 21, so that the inclined top 31 can move along the inclined supporting surface of the inclined top seat 32, and then the core-pulling mold 21 realizes the limiting effect on the inclined top 31, and the inclined top 31 moves in the direction away from the second undercut 12, so that the core-pulling mold 21 is disengaged from the first undercut 11, and the inclined top 31 is disengaged from the second undercut 12, completing the first disengagement.
[0046] Furthermore, a first limiting block 6 is fixedly installed at the bottom of the core-pulling mold 21. When the core-pulling assembly 2 and the inclined ejector assembly 3 are moved to the first demolding station driven by the driving member 4, the bottom of the first limiting block 6 can abut against the top of the core-pulling top plate 22 to limit the core-pulling assembly 2 and the inclined ejector assembly 3, so that the core-pulling mold 21 can no longer move independently, and the inclined ejector 31 is prevented from continuing to move along the inclined ejector seat 32 when the core-pulling mold 21 moves independently, causing the inclined ejector 31 to be separated from the inclined ejector seat 32, thereby causing damage to the device.
[0047] Furthermore, the core pulling assembly 2 also includes a second limit block 7. The second limit block 7 is vertically arranged and one end of the second limit block 7 is fixedly connected to the core pulling mold 21, and the other end of the second limit block 7 passes through the core pulling top plate 22 and the fixed seat 5 in sequence. By setting the second limit block 7, it is possible to limit the core pulling mold 21 so that the core pulling mold 21 can only move along the direction of the driving member 4. Preferably, two second limit blocks 7 are provided and the two second limit blocks 7 are mirror-symmetrical about the vertical center line of the core pulling top plate 22, which can prevent the core pulling mold 21 from deflecting and shifting, so that the movement of the core pulling mold 21 is more stable.
[0048] Furthermore, the core-pulling and tilting ejection device for releasing the injection-molded component of the automobile head-up display cover in this embodiment further includes a moving block 8 .

The moving block 8 is placed in the second slot 51 and the long through hole 221, and the moving block 8 can be separated from the second slot 51 by the extrusion of the core-pulling top plate 22, and can be moved laterally in the long through hole 221, and is engaged with the first slot 71. By setting a moving block 8, a first slot 71, a second slot 51 and a long through hole 221, and placing the moving block 8 in the second slot 51 and the long through hole 221, when the core pulling mold 21 moves to the first demolding station, the moving block 8 is stuck in the second slot 51 and placed in the long through hole 221, and when the core pulling mold 21 moves to the second demolding station, the first limiting block 6 presses against the core pulling top plate 22, so that the driving member 4 drives the core pulling mold 21 and the core pulling top plate 22 to move simultaneously, and then the moving block 8 squeezes the second slot 51 and moves along the long through hole 221 to engage with the first slot 71, so as to limit the second limiting block 7, and ensure that the core pulling mold 21 and the core pulling top plate 22 can move simultaneously when moving from the first demolding station to the second demolding station, thereby realizing that the inclined top 31 is separated from the first undercut 11. Preferably, the moving block 8 is a hexagon and the vertical cross-section of the moving block 8 at both ends of the first slot 71 and the second slot 51 is a triangle. The first slot 71 and the second slot 51 are both triangles that match the two ends of the moving block 8, so that the moving block 8 can cooperate with the first slot 71 and the second slot 51, so that the friction can be reduced when the moving block 8 squeezes the first slot 71 and the second slot 51, thereby preventing the second limit block 7 from being unable to be engaged with the moving block 8, thereby preventing the core pulling mold 21 from moving alone.
[0050] Through the above structure, the working principle of the core-pulling inclined ejector 31 device for releasing the injection molded part of the automobile head-up display cover in this embodiment is as follows:
[0051] like Figure 1 As shown, after the cover body 1 is formed, the core-pulling mold 21 cooperates with the first undercut 11 , and the top of the inclined top 31 cooperates with both the first undercut 11 and the second undercut 12 .
[0052] like Figure 6As shown, the driving member 4 retracts, driving the core-pulling mold 21 to move vertically, so that the top of the core-pulling mold 21 is separated from the first undercut 11. At the same time, the top of the inclined top 31 passes through the top of the core-pulling mold 21, and due to the vertical movement of the core-pulling mold 21, the T-shaped slider 311 at the bottom of the inclined top 31 is driven to move along the T-shaped slide groove 321 of the inclined top seat 32 on the inclined support surface. When the core-pulling mold 21 and the inclined top 31 reach the first demolding station driven by the driving member 4, the top of the inclined top 31 is separated from the second undercut 12, completing the first release.
[0053] like Figure 7 As shown, when the top of the inclined top 31 is separated from the second undercut 12, at this time, the top of the inclined top 31 is still matched with the first undercut 11. At this time, the bottom of the first limit block 6 abuts against the top of the core-pulling top plate 22, so that the core-pulling top plate 22, the core-pulling mold 21, the inclined top 31 and the inclined top seat 32 are a whole. The moving block 8, the first slot 71 and the second slot 51 are located in the same plane. The driving member 4 continues to retract, driving the core-pulling mold 21 to continue to descend. Since the moving block 8 is located in the long through hole 221 and the second slot 51, the core pulling top plate 22 and the core pulling mold 21 are a whole, and the driving member 4 drives the core pulling mold 21 to descend vertically, thereby driving the core pulling top plate 22 to descend vertically, so that the bottom of the moving block 8 squeezes the second slot 51, and the moving block 8 moves from the second slot 51 through the long through hole 221 to the first slot 71, and engages with the second limit block 7, so that the second limit block 7 and the core pulling top plate 22 form a whole, and the driving member 4 thereby drives the core pulling mold 21, the core pulling top plate 22, the inclined top 31, the inclined top seat 32, the first limit block 6, the second limit block 7 and the moving block 8 to move from the first demolding station to the second demolding station, that is, the core pulling top plate 22 descends vertically in the fixed seat 5, and the inclined top 31 moves in the direction away from the cover plate body 1. When arriving at the second demoulding station, the fixing seat 5 receives the core-pulling top plate 22 , and the inclined top 31 is separated from the first undercut 11 , thereby completing the separation of the inclined top 31 from the first undercut 11 and the second undercut 12 .
