Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to a device for removing irregularly shaped injection molded products. Background Technology

[0002] Existing methods for removing round (arc) injection molded products, such as pipe clamps, often employ expansion-type removal structures. These structures cause the product to expand and deform during removal, easily leading to dimensional errors. Furthermore, the single-design positioning structure causes internal stress during demolding of round or arc-shaped injection molded parts, resulting in inward or outward deformation of the ends. This can lead to loosening of the positioning and clamping structure, unstable clamping, and even parts falling off. Additionally, it hinders the removal of batches of injection molded parts, resulting in low injection molding efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the common problems with expansion-type injection molding part removal methods. These methods often result in the product being stretched and deformed during removal, leading to dimensional errors. Furthermore, the single-design positioning structure causes internal stress in round or arc-shaped injection molded parts during demolding, causing end deformation that leads to loosening of the positioning and clamping structure, unstable clamping, and even the part falling off. Additionally, the invention prevents the removal of batches of injection molded parts, resulting in low injection molding efficiency. Therefore, this invention provides a device for removing irregularly shaped injection molded products.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a device for removing irregularly shaped injection-molded products, comprising:

[0005] The base plate has an installation opening at its top;

[0006] A sprue clamp, which is rotatably disposed in the mounting port, includes a chassis, a plurality of top sealing plates connected to the chassis, and an elastic telescopic clamp piece movably disposed in the cavity between the chassis and the top sealing plates.

[0007] The irregular positioning component includes a positioning component body and a positioning shaft. The positioning component body is embedded in the mold. The end of the positioning component body cooperates with the positioning rib of the mold to abut and position the end of the irregular injection molded part. The mold is also provided with a first positioning seat and a second positioning seat for positioning the male and female connectors of the circular or arc-shaped irregular injection molded part. A positioning groove for the irregular positioning component to be sleeved and positioned is formed between several top sealing plates.

[0008] Several product fixing posts are inserted and connected to the irregularly shaped injection molded part;

[0009] A clamping mechanism is provided corresponding to the product fixing post, and works with the product fixing post to abut and position the irregular injection molded part.

[0010] As a further description of the above technical solution:

[0011] The top sealing plate is a fan-shaped plate with a wedge-shaped guide edge on the inner side, and the elastic telescopic clip is a fan-shaped clip.

[0012] As a further description of the above technical solution:

[0013] The base plate is provided with a pressing member on the outside of the sprue clamp. The pressing member passes through the through hole of the top cover plate of the base plate. An elastic member is provided between the pressing member and the cover plate. The bottom of the pressing member extends into the movable groove of the base plate. The chassis is provided with a locking groove corresponding to the pressing member.

[0014] As a further description of the above technical solution:

[0015] The elastic telescopic clip has an outwardly extending touch plate corresponding to the pressing element.

[0016] As a further description of the above technical solution:

[0017] The touch panel is a soft rubber touch panel.

[0018] As a further description of the above technical solution:

[0019] A positioning support rod is rotatably connected to the main body of the positioning component, and a locking component, which is a bolt or a pin, is provided between the main body of the positioning component and the positioning support rod.

[0020] As a further description of the above technical solution:

[0021] The clamping mechanism includes a clamping head driven by a clamping cylinder.

[0022] As a further description of the above technical solution:

[0023] The clamping head is a soft rubber clamping head.

[0024] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0025] 1. This injection molded product removal device is mainly used for the batch removal of injection molded parts of various sizes, round or arc-shaped. The irregularly shaped injection molded parts are inserted and connected through the product fixing pillars ejected from the mold. The irregularly shaped positioning parts are ejected from the mold simultaneously. The middle part is clamped and positioned by the sprue clamp, and the irregularly shaped injection molded parts are positioned by abutment on the inner side or end. The clamping mechanism abuts and positions the irregularly shaped injection molded parts on the outer side or the other end, thereby achieving multi-point stable clamping of batches of arc-shaped or round irregularly shaped injection molded parts. When moving to the unloading area, the clamping mechanism is released, and the irregularly shaped injection molded parts rotate under stress, which drives the irregularly shaped positioning parts to rotate. The inner abutment structure is released, thereby achieving stable support, clamping and unloading of irregularly shaped injection molded parts. Compared with common expansion and unloading structures, this can avoid the product being stretched and clamped during unloading, which can cause deformation and dimensional deviations. It can also avoid the problem of the injection molded parts deforming inward or outward due to internal stress during demolding, which can cause the injection molded parts to loosen from the positioning and clamping structure, resulting in unstable clamping and docking, or even the injection molded parts falling off.

[0026] 2. The linkage design of the touch plate on the elastic telescopic clamp and the pressing part inside the base plate can improve the stability of clamping the injection molded part, and realize the synchronization of the multi-point positioning release of the injection molded part with the release of the clamping mechanism, thereby improving the efficiency of product removal and unloading and the stability of movement.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example 1:

[0038] Please see Figure 1-5 The present invention provides a technical solution: a device for removing irregularly shaped injection-molded products, comprising:

[0039] Base plate 1, with an installation port on its top;

[0040] The water inlet clamp 2 is rotatably disposed in the mounting port, and includes a chassis 21, a plurality of top sealing plates 22 connected to the chassis 21, and an elastic telescopic clamping piece 24 movably disposed in the cavity between the chassis 21 and the top sealing plates 22.

[0041] The irregular positioning component 3 includes a positioning component body 31 and a positioning shaft 32. The positioning component body 31 is embedded in the mold 6. The end of the positioning component body 31 cooperates with the positioning rib 63 of the mold 6 to abut and position the end of the irregular injection molded part 7. The mold 6 is also provided with a first positioning seat 61 and a second positioning seat 62 for positioning the male and female connectors of the circular or arc-shaped irregular injection molded part 7. A positioning groove 23 for the irregular positioning component 3 to be sleeved and positioned is formed between several top sealing plates 22.

[0042] Several product fixing posts 4 are connected to the irregularly shaped injection molded part 7 through a passage;

[0043] The clamping mechanism 5 is provided in correspondence with the product fixing post 4, and works with the product fixing post 4 to abut and position the irregular injection molded part 7.

[0044] This injection molding product removal device is mainly used for the batch removal of injection molded parts of various sizes, round or arc-shaped. The irregularly shaped injection molded parts 7 ejected from the mold are inserted and connected via the product fixing post 4. The irregularly shaped positioning part 3 is simultaneously ejected from the mold, its middle part clamped and positioned by the sprue clamp 2, and its inner side or end is abutted and positioned. The clamping mechanism 5 abuts and positions the outer side or the other end of the irregularly shaped injection molded part 7, thereby achieving stable clamping of the arc-shaped or round irregularly shaped injection molded parts 7. When moved to the unloading area, the clamping mechanism 5 releases, and the irregularly shaped injection molded part 7 rotates under stress, thus... The rotating irregular positioning component 3 releases the inner abutment structure, thereby achieving stable support, clamping, and unloading of the irregular injection molded part 7. Compared with the common expansion and unloading structure, this avoids the deformation caused by the product being stretched and clamped during unloading, resulting in dimensional deviations. It also avoids the problem of the injection molded part deforming inward or outward due to internal stress during demolding of round or arc-shaped injection molded parts, which could lead to loosening of the positioning and clamping structure, unstable clamping and docking, or even the injection molded part falling off.

[0045] In this embodiment, in order to achieve stable support and clamping of the irregular positioning part 3, the top sealing plate 22 is a fan-shaped plate, and a wedge-shaped guide edge is provided on the inner side of the top sealing plate 22. The elastic telescopic clamp 24 is a fan-shaped clamp, so that the clamping and positioning area is located in the center of the sprue clamp 2 and the irregular positioning part 3, ensuring uniform and sufficient inner end contact and positioning of the irregular injection molded part 7 on each product fixing post 4.

[0046] A positioning support rod 33 is rotatably connected to the positioning component body 31. A locking component 34 is provided between the positioning component body 31 and the positioning support rod 33. The locking component 34 is a bolt or a pin. The irregularly shaped positioning component 3 is designed to be adjustable so that it can adapt to the positioning requirements of injection molded parts of different sizes of injection molds.

[0047] The clamping mechanism 5 includes a clamping head 51 driven by a clamping cylinder, wherein the clamping head 51 is a soft rubber clamping head, which ensures stable and non-destructive clamping and positioning of irregularly shaped injection molded parts.

[0048] In use, after the irregular injection molded part 7 is injection molded, the robot arm moves the base plate 1 to the mold 6, aligning the product fixing post 4 with the center of the product hole inside the mold 6; the ejector pin inside the mold 6 ejects it along with the irregular positioning part 3, the positioning groove 23 of the sprue clamp 2 clamps the irregular injection molded part 7, and the elastic telescopic clamp 24 buffers it; the irregular injection molded part 7 is sleeved on the product fixing post 4, and the clamping cylinder drives the clamping head 51 to clamp and position the outer side of the irregular injection molded part 7, cooperating with the inner positioning of the irregular positioning part 3 to achieve a circular or... The ends of the arc-shaped injection molded parts are positioned at multiple points to prevent the parts from deforming inward or outward due to internal stress. This would cause the parts to loosen from the positioning and clamping structure, leading to unstable clamping and even the parts falling off. The robot moves the base plate 1 to the product placement area, and the clamping cylinder retracts, causing the irregularly shaped injection molded part 7 and the irregularly shaped positioning part 3 to rotate together. This releases the positioning of the product, allowing the product to be unloaded. The irregularly shaped positioning part 3 is then removed and assembled onto the mold 6 for the next set of injection molded parts to be manufactured.

[0049] Example 2:

[0050] Please see Figure 1-3 Based on the above embodiment 1, preferably, the base plate 1 is provided with a pressing member 12 on the outside of the water inlet clamp 2, the pressing member 12 passes through the through hole of the top cover plate 11 of the base plate 1, an elastic member 14 is provided between the pressing member 12 and the cover plate 11, the bottom of the pressing member 12 extends into the movable groove 13 of the base plate 1, and the chassis 21 is provided with a locking groove 211 corresponding to the pressing member 12.

[0051] The elastic telescopic clip 24 has an outwardly extending touch plate 25 corresponding to the pressing member 12.

[0052] The touch panel 25 is a soft rubber touch panel.

[0053] Through the above design, the sprue clamp 2 can move when docking with the irregular injection molded part 7 for quick and accurate docking. After docking, the elastic telescopic clamp 24 moves outward, simultaneously driving the touch plate 25 to press the pressing part 12, thereby locking the sprue clamp 2, the irregular positioning part 3, and the base plate 1, and positioning the irregular positioning part 3 to ensure stable and efficient clamping and positioning of the injection molded part, avoiding the problem of unstable clamping and falling due to its opening and movement. After the clamping mechanism 5 is released, the rotation of the injection molded part drives the irregular positioning part 3 to move initially, causing the touch plate 25 on the sprue clamp 2 to shift away from the pressing part 12. The elastic part 14 drives the pressing part 12 to move upward and reset, thereby releasing the positioning of the sprue clamp 2 and the base plate 1. The rotation of the irregular positioning part 3 releases the positioning of the irregular injection molded part 7. This design improves the stability of clamping the injection molded part and achieves synchronization with the release of the multi-point positioning of the injection molded part after the clamping mechanism 5 is released, thereby improving the efficiency of product removal and unloading and the stability of movement.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
