Description

Technical Field

[0001] This utility model belongs to the technical field of injection molds, specifically relating to a slider sleeve spring-driven inclined ejector. Background Technology

[0002] In plastic mold design, for parts with undercut structures, a slider sleeve with a slanted ejector is typically required at the corresponding undercut position to facilitate the forming of the undercut and subsequent demolding. To ensure the proper operation of the slider sleeve with the slanted ejector, an ejector plate is usually designed on the back of the slider for mounting the ejector. This increases the overall volume of the slider sleeve with the slanted ejector, necessitating a corresponding increase in the mold plate size and thus increasing mold usage costs. Furthermore, for parts with limited space during injection molding, and to avoid interference from moving parts during demolding, the slider sleeve with the slanted ejector needs to have a minimal volume and stroke while ensuring sufficient space for disengagement from the undercut. Existing slider sleeve with slanted ejector structures cannot meet these requirements.

[0003] Therefore, this utility model addresses the needs of limited space in injection molds, the requirement for minimal travel of movable parts, and the need to ensure smooth disengagement of the inclined ejector from the undercut part, by disclosing a slider sleeve spring-driven inclined ejector. Utility Model Content

[0004] This utility model discloses a slider sleeve spring-driven inclined ejector, which can adapt to narrow mold space to form the undercut structure of the part and facilitate subsequent demolding. In addition, it effectively controls the stroke of the movable part during demolding to avoid interference between the movable part and the part.

[0005] This utility model is achieved through the following technical solution: A slider sleeve spring-driven inclined top includes a moving template, a linear drive component, and an elastic abutment component. A slider is slidably disposed on the side of the moving template away from the part, and one side of the slider is connected to the linear drive component. A square inclined top is slidably disposed side-by-side inside the end of the slider closer to the part. During the sliding process, the slider can compress the side-by-side square inclined tops to move away from or closer to each other. An inclined top slide block is disposed on the end of the slider away from the part. The end of the square inclined top away from the part is slidably connected to one side of the inclined top slide block along the direction of mutual movement of the square inclined tops. An elastic abutment component is disposed on the side of the inclined top slide block away from the part.

[0006] In the injection molding state, the end of the angled ejector near the part connects and assembles with the side of the slider near the part to form a molding cavity corresponding to the undercut contour on the part. After the part is formed by injection molding, the linear drive drives the slider to move a first stroke away from the part in a first direction. The slider compresses the side-by-side angled ejectors, causing them to move away from each other in a second direction perpendicular to the first direction. This causes the angled ejectors to detach from the undercut of the part. During the first stroke of the linear drive, the slider does not contact the angled ejector slide. At the same time, the angled ejector slide remains stationary under the elastic force of the elastic abutment to hold the angled ejectors in place, so that the angled ejectors can only move relative to each other in the second direction, but not in the first direction. Then, the linear drive continues to drive the slider to move a second stroke away from the part. The elastic force of the elastic abutment is overcome, and the slider contacts the angled ejector slide and drives the angled ejector slide to move synchronously away from the part. This allows the angled ejectors to move along the first direction away from the part, ultimately achieving part demolding.

[0007] To better realize this utility model, the slider is further provided with a V-shaped inclined groove at one end near the part, and the square inclined top is slidably fitted inside the inclined groove. The inclined groove includes an inner inclined surface and an outer inclined surface. When the inner inclined surface presses the square inclined top, the side-by-side square inclined tops move away from each other. When the outer inclined surface presses the square inclined top, the side-by-side square inclined tops move closer to each other.

[0008] To better realize this utility model, the inclined top slide block is further provided with a T-shaped groove on the side near the slider, and the square inclined top is provided with a T-shaped block that is slidably connected to the T-shaped groove at the end away from the part.

[0009] To better realize this utility model, a limiting surface is further provided on the side of the inclined top slide block near the slider.

[0010] To better realize this utility model, the elastic abutment includes an elastic element and a fixing block. One end of the elastic element is connected to the side of the inclined top slide away from the part, and the other end of the guide rod is connected to the fixing block through the elastic element.

[0011] To better realize this utility model, the elastic element further includes a guide rod and a spring. One end of the guide rod is connected to the side of the inclined slide away from the part by a screw, and the other end of the guide rod is in contact with one end of the spring. The other end of the spring is in contact with the fixing block.

[0012] To better realize this utility model, the square inclined top is further provided with a shaped protrusion or a shaped recess at the end near the part corresponding to the undercut position of the part.

[0013] To better realize this utility model, the linear drive component further includes a drive cylinder and an adapter seat. The push rod end of the drive cylinder is connected to the bottom of the adapter seat, and the side of the adapter seat closest to the component is connected to the slider.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention uses a linear drive to move a slider during a first stroke, and an elastic abutment keeps the inclined ejector slide stationary during the first stroke. The slider then presses against the side-by-side square inclined ejectors, causing them to move away from each other and smoothly disengage from the undercut position of the part. After the square inclined ejectors disengage from the undercut position of the part, the linear drive continues to move the slider to abut against the inclined ejector slide, causing the inclined ejector slide and the square inclined ejectors to move away from the part. This prevents the slider from pressing against the square inclined ejectors, thus adapting to narrow mold spaces and allowing the part to be demolded smoothly, while effectively avoiding interference from moving parts.

Detailed Implementation

[0017] Example 1: In this embodiment, a slider sleeve spring-driven inclined top is provided, such as Figures 1-4As shown, it includes a moving template 1, a linear drive component 2, and an elastic abutment component 3. A slider 4 is slidably disposed on the side of the moving template 1 away from the part, and one side of the slider 4 is connected to the linear drive component 2. A square inclined top 5 is slidably disposed side by side inside the end of the slider 4 near the part. During the sliding process, the slider 4 can compress the square inclined tops 5 arranged side by side to move away from or towards each other. An inclined top slide 6 is disposed on the end of the slider 4 away from the part. The end of the square inclined top 5 away from the part is slidably connected to one side of the inclined top slide 6 along the direction in which the square inclined tops 5 move towards each other. An elastic abutment component 3 is disposed on the side of the inclined top slide 6 away from the part.

[0018] A groove is provided on the moving template 1 along the first direction, and the slider 4 is slidably connected to the groove. A moving template limiting surface is provided at the end of the groove near the part. When the linear drive 2 drives the slider 4 to slide towards the part to the limit position, the end face of the slider 4 near the part abuts against the moving template limiting surface. At this time, the slider 4 is in the injection molding station. At the same time, the slider 4 squeezes the side-by-side square inclined tops 5 closer to each other, so that the shape of the square inclined tops 5 and the shape of the slider 4 are connected and spliced ​​to form the injection cavity of the corresponding undercut contour of the part. When the slider 4 is in the injection molding station, there is a first stroke movement gap between the slider 4 and the inclined top slide 6.

[0019] After the part is injection molded, the linear drive 2 drives the slider 4 to slide away from the part along the first direction for a first stroke. The slider 4 then presses against the angled tops 5, causing the side-by-side angled tops 5 to move away from each other along a second direction perpendicular to the first direction, thus disengaging the angled tops 5 from the undercut of the part. During the first stroke, the slider 4 does not contact the angled top slide 6. The angled top slide 6 remains stationary under the elastic force of the elastic contact 3, ensuring that the side-by-side angled tops 5 can only move away from each other along the second direction and not along the first direction. After the first stroke, the linear drive 2 drives the slider 4 to continue moving for a second stroke. At this point, the slider 4 contacts the angled top slide 6 and drives the angled top slide 6 to overcome the elastic force and move along the first direction. Because the slider 4 and the angled top slide 6 move synchronously at this time, the slider 4 no longer presses against the angled tops 5. The angled tops 5 then move away from the part along the first direction along with the angled top slide 6 and no longer move away from each other along the second direction.

[0020] Furthermore, the square inclined top 5 has a shaped protrusion or a shaped recess at one end near the part, corresponding to the undercut position of the part.

[0021] Example 2: This embodiment is a further optimization based on Embodiment 1, such as... Figure 6As shown, the slider 4 has a V-shaped inclined groove 100 inside one end near the part. The square inclined top 5 is slidably fitted inside the inclined groove 100. The inclined groove 100 includes an inner inclined surface 101 and an outer inclined surface 102. When the inner inclined surface 101 presses the square inclined top 5, the side-by-side square inclined tops 5 move away from each other. When the outer inclined surface 102 presses the square inclined top 5, the side-by-side square inclined tops 5 move closer to each other.

[0022] During the first stroke of the slider 4 moving away from the part in the first direction, the inner inclined surface 101 presses against the square inclined top 5, causing the side-by-side square inclined tops 5 to move away from each other, thereby disengaging the square inclined tops 5 from the part. During the first stroke of the slider 4 moving closer to the part in the first direction, the outer inclined surface 102 presses against the square inclined top 5, causing the side-by-side square inclined tops 5 to move closer to each other, thereby resetting the square inclined tops 5.

[0023] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0024] Example 3: This embodiment is a further optimization based on the above embodiment 1 or 2, such as... Figure 5 As shown, the inclined slide block 6 has a T-shaped groove 201 on the side near the slider 4, and the square inclined top 5 has a T-shaped block 202 at the end away from the part, which is slidably connected to the T-shaped groove 201. The T-shaped groove 201 is arranged along the second direction, and the T-shaped block 202 is slidably connected to the T-shaped groove 201 along the second direction, so that the square inclined top 5 can move relative to the inclined slide block 6 along the second direction, thereby realizing the mutual approach or mutual distance movement of the side-by-side square inclined tops 5.

[0025] Furthermore, a limiting surface 200 is provided on the side of the inclined top slide block 6 near the slider 4. When the slider 4 moves along the first direction to contact the limiting surface 200, the slider 4 can drive the inclined top slide block 6 to move synchronously along the first direction.

[0026] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.

[0027] Example 4: This embodiment is a further optimization based on any one of embodiments 1-3 above, such as... Figure 3 and Figure 4 As shown, the elastic abutment 3 includes an elastic element and a fixing block. One end of the elastic element is connected to the side of the inclined slide 6 away from the part, and the other end of the guide rod 31 is connected to the fixing block through the elastic element. The elastic element includes a guide rod 31 and a spring 32. One end of the guide rod 31 is connected to the side of the inclined slide 6 away from the part by a screw, and the other end of the guide rod 31 is connected to one end of the spring 32. The other end of the spring 32 is connected to the fixing block.

[0028] When slider 4 is not in contact with the inclined slide block 6, the inclined slide block 6 remains stationary under the elastic force of spring 32, pressing against the end of the square inclined pusher 5 away from the part. At this time, the movement of slider 4 in the first direction can only cause the side-by-side square inclined pushers 5 to move closer or further apart, but cannot cause the square inclined pushers 5 to move in the first direction. When slider 4 contacts the inclined slide block 6, the inclined slide block 6 overcomes the elastic force of spring 32 and moves synchronously with slider 4. At this time, the movement of slider 4 in the first direction can only cause the square inclined pushers 5 to move in the first direction, but cannot continue to press the square inclined pushers 5 closer or further apart in the second direction.

[0029] The other parts of this embodiment are the same as any one of the embodiments 1-3 above, so they will not be described again.

[0030] Example 5: This embodiment is a further optimization based on any one of embodiments 1-4 above, such as... Figure 1 As shown, the linear drive component 2 includes a drive cylinder 21 and an adapter 22. The push rod end of the drive cylinder 21 is connected to the bottom of the adapter 22, and the side of the adapter 22 closest to the component is connected to the slider 4.

[0031] The push rod end of the drive cylinder 21 is provided with a locking block, and the bottom of the adapter 22 is provided with a locking groove. The locking groove engages with the locking block, so that the push rod of the drive cylinder 21 can drive the adapter 22 to move synchronously in the first direction. The side of the adapter 22 closest to the part is connected to the slider 4, so the drive cylinder 21 can drive the slider 4 to move in the first direction.

[0032] The other parts of this embodiment are the same as any one of the embodiments 1-4 above, so they will not be described again.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
