Description

Technical Field

[0001] This utility model relates to the field of injection molds, specifically to a slanted ejector mechanism and a mold. Background Technology

[0002] Angled ejector mechanisms are common structures in molds. For example, a patent for a large-angle angled ejector demolding structure, with Chinese patent authorization announcement number CN221819405U, discloses an angled ejector mechanism.

[0003] The existing inclined jacking mechanism includes an inclined jack block, an inclined jack rod, an inclined jack seat, and a guide rod. A slider is mounted on the inclined jack seat, the inclined jack rod is fixedly connected to the slider, and the inclined jack block is fixedly connected to the inclined jack rod. The slider and the guide rod are slidably engaged, and the guide rod and the inclined jack rod are arranged parallel to each other. In this way, the inclined jack seat pushes the inclined jack rod to move via the slider, the inclined jack rod pushes the inclined jack block, and simultaneously the slider slides along the guide rod. The guide rod guides the axial movement of the inclined jack rod and also supports and reinforces it, preventing bending and deformation during movement.

[0004] However, due to manufacturing or installation errors, the angled push rod and the support rod cannot be guaranteed to be perfectly parallel, and a small angular deviation may exist between them. This can cause the slider to jam on the support rod when it slides, as the angled push rod and the support rod cannot be perfectly parallel, thus affecting the normal movement of the angled push rod. To solve this problem, the current common practice is to increase the tolerance between the slider and the support rod (or the angled push rod). However, this increased tolerance makes the slider and the support rod (or the angled push rod) looser, which obviously affects the stability and support provided by the support rod to the angled push rod. Utility Model Content

[0005] The present invention aims to provide a slanted ejector mechanism and a mold to solve the problem of jamming that occurs during the movement of the slanted ejector rod mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inclined top mechanism, comprising an inclined top rod, a support rod, and an inclined top seat, wherein the inclined top rod and the support rod are arranged in parallel, and a slider unit is provided on the inclined top seat. The slider unit includes a fixed part, a first rotating part, and a second rotating part. The first rotating part and the second rotating part are both rotatably connected to the fixed part. The first rotating part is axially fixed to the inclined top rod, and the second rotating part is slidably connected to the support rod along the axial direction of the support rod. The slider unit is slidably disposed on the inclined top seat.

[0007] To achieve the above objectives, the present invention also adopts the following technical solution: a mold, including a slanted ejector mechanism.

[0008] The principle and advantages of this application are as follows: The slider unit in this application is located on the inclined top seat. The first rotating part on the slider unit is axially fixed to the inclined top rod (the first rotating part and the inclined top rod will not move relative to each other along the axial direction of the inclined top rod). The second rotating part is slidably engaged with the support rod. In this way, when the inclined top seat moves, the inclined top rod is pushed to move axially through the fixed connection between the first rotating part on the slider unit and the inclined top rod. At the same time, the second rotating part on the slider unit slides along the axial direction of the support rod. The support rod plays a guiding, supporting and reinforcing role in the movement of the inclined top rod, and the inclined top rod is not easy to break or be damaged.

[0009] During the movement of the inclined push rod, since both the first and second rotating parts are rotatably connected to the fixed part, even if the inclined push rod and the support rod are not perfectly parallel due to machining errors, installation errors, or other reasons, the first and second rotating parts will not be fixed in place. They can rotate appropriately, thus achieving self-correction of the first and second rotating parts according to the axial direction of the inclined push rod and the support rod during movement. The second rotating part slides more smoothly on the support rod, making it easier for the slider unit to push the inclined push rod to move. There is no need to increase the fit tolerance between the second rotating part and the support rod or the first rotating part and the inclined push rod. This ensures that the support rod plays its due role in the inclined push rod while preventing the slider unit from getting stuck on the support rod.

[0010] Preferably, as an improvement, the fixing part is provided on both sides of the first rotating part and both sides of the second rotating part, and both sides of the first rotating part and both sides of the second rotating part are rotatably connected to the fixing part.

[0011] Therefore, the fixing part is provided on both sides of the first rotating part and both sides of the second rotating part. The fixing part clamps the first rotating part and the second rotating part from both sides, and the first rotating part and the second rotating part are more stably mounted on the fixing part.

[0012] Preferably, as an improvement, the inclined top seat includes two clamping walls, with the slider unit located between the two clamping walls.

[0013] Therefore, the clamping wall holds the slider unit from both sides, making the slider unit more stable when mounted on the inclined top seat and sliding on the inclined top seat.

[0014] Preferably, as an improvement, the inner wall of the clamping wall is provided with a groove, and the fixing part is slidably located in the groove. Thus, by the fixing part sliding in the groove on the inner wall of the clamping wall, the sliding of the slider unit on the inclined top seat is realized.

[0015] Preferably, as an improvement, both sides of the first rotating part and both sides of the second rotating part are rotatably connected to the fixed part via a rotating shaft.

[0016] Preferably, as an improvement, the second rotating part is provided with a rod hole, through which the support rod passes and is slidably connected to the second rotating part.

[0017] Thus, by passing the handrail through the rod hole, a sliding connection between the second rotating part and the handrail is achieved.

[0018] Preferably, as an improvement, the first rotating part is provided with a stepped hole, the end of the inclined push rod is a stepped end, the stepped end is inserted into the stepped hole, and the step surface of the stepped end abuts against the step surface of the stepped hole; the end of the inclined push rod extends out from the stepped hole and is connected to a fixing component, and the fixing component abuts against the first rotating part.

[0019] Therefore, by abutting the stepped surface of the stepped end against the stepped surface of the stepped hole, when the first rotating part pushes the inclined push rod towards the inclined push block, the first rotating part and the inclined push rod will not slide axially relative to each other, thus achieving axial fixation of the first rotating part and the inclined push rod. Since the fixing component abuts against the first rotating part, when the first rotating part moves away from the inclined push block, the first rotating part pushes the fixing component away from the inclined push block by abutting against it. The fixing component then drives the inclined push rod to move away from the inclined push block, thereby achieving axial fixation of the first rotating part and the inclined push rod.

[0020] Preferably, as an improvement, the fixing component includes a nut and a sleeve, the nut and the inclined push rod are threaded together, the sleeve is fitted onto the inclined push rod, one end of the sleeve abuts against the first rotating part, and the other end of the sleeve abuts against the nut.

[0021] Therefore, the sleeve acts as abutment against the first rotating part. Even if the thread at the end of the inclined push rod is not set to the first rotating part, making it impossible for the nut to abut against the first rotating part, by setting the sleeve, the nut abuts against the sleeve, and the sleeve abuts against the first rotating part, thereby fixing the first rotating part. The setting of the sleeve can solve the problem that the nut cannot rotate to the first rotating part and thus cannot tighten and fix the first rotating part.

[0022] Preferably, as an improvement, the inner wall of the stepped hole is provided with a first engaging surface, and the side wall of the inclined push rod is provided with a second engaging surface that mates with the first engaging surface. Thus, through the engagement of the first and second engaging surfaces, the inclined push rod will not rotate within the stepped hole of the first rotating part, thereby preventing the inclined push rod from rotating.

[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: 1. inclined rod, 2. support rod, 3. inclined block, 4. inclined seat, 5. groove, 6. fixing part, 7. first rotating part, 8. second rotating part, 9. sleeve, 10. nut, 11. first step surface, 12. pin, 13. screw, 14. second snap-fit ​​surface, 15. second step surface, and 16. rotating shaft.

[0031] The basic implementation examples are as follows: Figures 1-6 As shown: This embodiment discloses a slanted ejector mechanism applied to a mold, including a slanted ejector rod 1, a slanted ejector block 3, a support rod 2, and a slanted ejector seat 4. The slanted ejector rod 1 and the support rod 2 are arranged in parallel (although the slanted ejector rod 1 and the support rod 2 are arranged in parallel, due to machining errors and installation errors, there are more or less imperceptible parallel deviations in the whole or in some parts of the slanted ejector rod 1 and the support rod 2, so that the slanted ejector rod 1 and the support rod 2 are not in an ideal state of absolute parallelism. Of course, this deviation is small and not easily noticed by the naked eye). One end of the slanted ejector rod 1 is fixed to the slanted ejector block 3, and the end of the support rod 2 is fixed to the mold and will not move axially.

[0032] The improvement of this embodiment is that the inclined top seat 4 in this embodiment is provided with a slider unit, combined with... Figure 2As shown, the slider unit includes a fixed part 6, a first rotating part 7, and a second rotating part 8. In this embodiment, the fixed part 6 consists of two guide vanes, which are located on both sides of the first rotating part 7 and the second rotating part 8, respectively. Both the first rotating part 7 and the second rotating part 8 are block-shaped, and a rotating shaft 16 is integrally formed on both sides of the first rotating part 7 and the second rotating part 8. The guide vanes are provided with rotating holes, and the rotating shaft 16 is assembled into the rotating holes, thereby realizing that both the first rotating part 7 and the second rotating part 8 are rotatably connected to the fixed part 6. In this embodiment, the first rotating part 7 and the inclined rod 1 are axially fixed (the fixing method is such as welding, bolt fixing, or axial snap-fit, etc.). The second rotating part 8 is slidably connected to the support rod 2 along the axial direction of the support rod 2. Specifically, the second rotating part 8 is provided with a rod hole, and the support rod 2 passes through the rod hole and slides relative to it. In this embodiment, the fixing part 6 is slidably disposed on the inclined top seat 4. Specifically, the inclined top seat 4 includes two clamping walls that are detachably connected. Each clamping wall has a groove 5 on its inner wall, and a guide slide is slidably assembled in the groove 5. Thus, the entire slider unit can slide relative to the inclined top seat 4 along the groove 5.

[0033] Therefore, when the inclined top seat 4 moves along the support rod 2, the second rotating part 8 slides axially on the support rod 2, while the first rotating part 7 pushes the inclined top rod 1 to move axially, and the inclined top rod 1 drives the inclined top block 3 to move. During the movement of the inclined top rod 1, since both the first rotating part 7 and the second rotating part 8 are rotatably connected to the fixed part 6, even if the inclined top rod 1 and the support rod 2 are not perfectly parallel due to machining errors, installation errors, etc., the first rotating part 7 and the second rotating part 8 will not be fixed. The first rotating part 7 and the second rotating part 8 can rotate appropriately on the fixed part 6 according to the deviation of the inclined top rod 1 and the support rod 2, thus achieving self-correction of the first rotating part 7 and the second rotating part 8 along the directions of the inclined top rod 1 and the support rod 2 respectively during movement. This avoids the influence of the parallel deviation of the inclined top rod 1 and the support rod 2, and prevents the slider unit from jamming during axial movement. At the same time, there is no need to increase the fit tolerance between the second rotating part 8 and the support rod 2, thus ensuring that the support rod 2 plays its due role in the inclined top rod 1.

[0034] Furthermore, this embodiment also specifically discloses the fixing method of the first rotating part 7 and the inclined push rod 1, combined with Figure 4-Figure 6As shown, in this embodiment, the first rotating part 7 is provided with a stepped hole, and a first step surface 11 is provided in the stepped hole. The end of the inclined push rod 1 is a stepped end (the diameter of the bottom end of the inclined push rod 1 becomes smaller to form a stepped end). A second step surface 15 is provided at the junction of the small diameter and the large diameter on the side of the stepped end of the inclined push rod 1. The stepped end of the inclined push rod 1 is inserted into the stepped hole, and the second step surface 15 of the stepped end abuts against the first step surface 11 of the stepped hole. At the same time, the bottom end of the inclined push rod 1 extends from the bottom of the first rotating part 7, and a fixing component is connected to the part of the end of the inclined push rod 1 that extends out of the stepped hole. In this embodiment, the fixing component abuts against the first rotating part 7. Specifically, the fixing component includes a nut 10 and a sleeve 9. The sleeve 9 is fitted onto the inclined push rod 1, with one end of the sleeve 9 abutting against the bottom of the first rotating part 7 and the other end abutting against the nut 10. The nut 10 is threaded onto the small end of the inclined push rod 1. By tightening the nut 10, the nut 10 is pressed against the sleeve 9, and the sleeve 9 abuts against the bottom of the first rotating part 7. Thus, this structure achieves axial fixation of the first rotating part 7 and the inclined push rod 1. When the inclined push seat 4 moves axially upward on the support rod 2, the first rotating part 7 pushes the inclined push rod 1 upward through the abutment of the first step surface 11 and the second step surface 15. When the inclined push seat 4 moves axially downward on the support rod 2, the bottom of the first rotating part 7 abuts against the sleeve 9, causing the inclined push rod 1 to move downward.

[0035] In this embodiment, the axial fixing method of nut 10, sleeve 9 and first rotating part 7 is adopted. By tightening nut 10, nut 10 is pressed against sleeve 9, and sleeve 9 is pressed against first rotating part 7. The length of sleeve 9 can be changed according to the actual distance between nut 10 and first rotating part 7. In this way, even if nut 10 is far away from first rotating part 7, first rotating part 7 can be axially fixed on inclined push rod 1.

[0036] In this embodiment, the first rotating part is fixed in the same way as described above. The first rotating part is fixed to the inclined rod along the axial direction of the inclined rod. The first rotating part is rotatably mounted on the fixed part. During the sliding process of the slider unit along the support rod, the first rotating part can adaptively rotate according to the tilt deviation of the inclined rod. In this way, the radial assembly tolerance between the first rotating part and the inclined rod does not need to be set too large, thereby ensuring the support and stability of the support rod on the inclined rod.

[0037] In addition, in some embodiments, the inner wall of the stepped hole in this embodiment is provided with a first engaging surface, and the side wall of the inclined push rod 1 is provided with a second engaging surface 14 that mates with the first engaging surface. Thus, the first rotating part 7 is mounted on the inclined push rod 1, and the engagement of the first engaging surface and the second engaging surface 14 prevents the inclined push rod 1 from rotating on the first rotating part 7. In this embodiment, the inner wall of the stepped hole of the first rotating part 7 is provided with a pin groove, which is located above the first stepped surface 11. A pin 12 is placed in the pin groove, and the pin 12 is fixed to the first rotating part 7 by a screw 13. The side of the pin 12 located within the stepped groove serves as the first engaging surface. Using the method of assembling the pin 12 into the pin groove to form the first engaging surface, instead of directly machining the first engaging surface within the stepped hole, helps to reduce machining difficulty and cost.

[0038] Furthermore, it should be noted that the fixing part 6 in this embodiment is not necessarily sheet-like; it can also be block-like or other shapes. The fixing part 6 on the first rotating part 7 and the fixing part 6 on the second rotating part 8 do not need to be connected as a single unit. Moreover, the first rotating part 7 and the second rotating part 8 can rotate on the fixing part 6 using other rotational engagement methods. For example, the rotating shaft 16 can be disposed on the fixing part 6, and rotating holes can be provided on the side surfaces of the first rotating part 7 and the second rotating part 8. The sliding method of the slider unit on the inclined top seat 4 is also not limited to the method described in this embodiment.

[0039] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
