Description

Technical Field

[0001] This application relates to the technical field of injection molded product processing, and in particular to a burr hot melt device for injection molded parts. Background Technology

[0002] During the injection molding process, due to factors such as mold wear, insufficient mold closing pressure, and the use of highly fluid plastics as the injection material, burrs may easily form at the injection gate (gate) of the injection molded part. This not only affects the appearance of the product but may also cause assembly interference, poor sealing, or even safety hazards.

[0003] Currently, the main method is to manually remove burrs using knives or sandpaper. However, this method is inefficient, labor-intensive, and prone to scratches or dimensional deviations due to improper operation, making it difficult to ensure processing consistency. Utility Model Content

[0004] To address the issues of low efficiency and inconsistency in manually removing burrs from injection molded parts, this application provides a burr hot-melt device for injection molded parts.

[0005] This application provides a burr hot melt device for injection molded parts, which adopts the following technical solution:

[0006] A hot-melt device for removing burrs from injection molded parts includes a worktable with a hot-melt mechanism. The hot-melt mechanism includes a clamping mechanism fixedly mounted on the worktable for holding the injection molded parts. The clamping mechanism includes at least two opposing clamping cylinders. The pistons of the clamping cylinders are fixedly mounted with clamping blocks. A support frame is fixedly mounted on the worktable around the clamping mechanism. A hot-melt plate is slidably mounted on the support frame. A hot-melt cylinder is fixedly mounted at the top of the support frame. The pistons of the hot-melt cylinders are fixedly connected to the hot-melt plate. A hot-melt head facing the clamping mechanism is fixedly mounted on the hot-melt plate. The hot-melt head is electrically connected to a controller.

[0007] By adopting the above technical solution, the injection molded part is placed in the clamping mechanism. The clamping cylinder, controlled by the controller, drives the clamping block to clamp and fix the injection molded part, which can stably fix the injection molded part and prevent displacement during the hot melting process, thereby improving processing accuracy and consistency. The hot melt plate, which is slidably installed on the support frame, and the hot melt cylinder, which is fixed at the top, control the movement of the hot melt plate on the support frame through the hot melt cylinder, thereby realizing the processing of the injection molded part. Moreover, the movement position of the hot melt plate can be precisely controlled according to the size of the injection molded part, ensuring that the hot melt head can accurately act on the burr area of ​​the injection molded part. The hot melt head is electrically connected to the controller, so that the working state of the hot melt head is controlled and adjustable, further improving the processing flexibility and efficiency. This effectively solves the problems of low efficiency, high labor intensity, and easy damage to products in traditional manual deburring methods, and significantly improves processing quality and production efficiency.

[0008] Preferably, the hot-melt mechanism further includes a locking mechanism disposed between the hot-melt plate and the clamping mechanism. The locking mechanism includes a support plate, a locking cylinder, and a locking plate. The support plate is fixedly installed on the support frame, and a locking cylinder is fixedly installed at the free end of the support plate. The movement direction of the locking cylinder is perpendicular to that of the clamping cylinder, and a locking plate is fixedly installed on the piston of the locking cylinder.

[0009] By adopting the above technical solution, the locking cylinder drives the locking plate to move towards the injection molded part, enabling the locking plate to lock the injection molded part. Furthermore, the movement direction of the locking cylinder is perpendicular to the movement direction of the clamping cylinder, ensuring that all four sides of the injection molded part are clamped and fixed. This effectively prevents displacement or vibration of the injection molded part during the hot-melt process, improving processing accuracy and consistency. Simultaneously, the locking plate's locking of the injection molded part helps in its positioning, ensuring that the hot-melt head on the hot-melt plate can accurately process the injection molded part.

[0010] Preferably, a buffer pad is fixedly installed on the side of the locking plate away from the locking cylinder.

[0011] By adopting the above technical solution, a buffer pad is fixedly installed on the side of the locking plate away from the locking cylinder, which can effectively protect the surface of the injection molded part from damage. During the clamping process, the buffer pad can disperse the clamping force, avoiding indentations or deformation on the surface of the injection molded part due to excessive clamping force, thereby improving the appearance quality of the processed product and reducing the scrap rate.

[0012] Preferably, a transfer mechanism is also fixedly installed beside the hot-melting mechanism of the workbench. The transfer mechanism includes a transfer bracket fixedly installed on the workbench. A first transfer cylinder with its movement direction parallel to the top surface of the workbench is fixedly installed on the transfer bracket. The piston of the first transfer cylinder is fixedly connected to a second transfer cylinder with its movement direction perpendicular to the top surface of the workbench. A transfer head is fixedly installed on the piston of the second transfer cylinder. A suction nozzle is fixedly installed on the side of the transfer head near the top surface of the workbench. The suction nozzle is connected to a vacuum pump. The first transfer cylinder, the second transfer cylinder, and the vacuum pump are electrically connected to a controller.

[0013] By adopting the above technical solutions, the transfer mechanism enables the injection molded parts to be automatically transferred after hot melting, improving processing efficiency and reducing the need for manual intervention. The combined use of the first and second transfer cylinders enables precise movement of the injection molded parts in both horizontal and vertical directions, ensuring the stability and accuracy of the transfer process. The combination of the suction nozzle and the vacuum pump firmly adheres to the injection molded parts, preventing them from falling off or being damaged during the transfer process, while also ensuring the gentleness of the transfer operation and reducing damage to the surface of the injection molded parts.

[0014] Preferably, the workbench further includes a conveying mechanism, which includes a conveying track on the workbench. The clamping mechanism also includes a receiving plate. The clamping cylinder is fixedly mounted on the receiving plate, and the receiving plate is slidably connected to the conveying track. A conveying cylinder is fixedly mounted on the workbench, and the piston of the conveying cylinder is fixedly connected to the receiving plate. The conveying cylinder realizes the conveying of the clamping mechanism between the hot melting mechanism and the transfer mechanism. The conveying cylinder is electrically connected to the controller.

[0015] By adopting the above technical solution, the conveying mechanism enables the clamping mechanism to automatically transfer between the hot-melt mechanism and the transfer mechanism, thereby achieving efficient transfer of injection molded parts between different processing stations. The conveying track provides a stable sliding path for the receiving plate, ensuring precise positioning of the clamping mechanism during movement; the conveying cylinder drives the receiving plate to move along the conveying track, avoiding the tedious manual handling operations, significantly improving processing efficiency and reducing labor intensity; in addition, the entire conveying process is uniformly controlled by a controller, ensuring the coordination and consistency of actions, further improving the automation level of the device and processing quality.

[0016] Preferably, a heat insulation plate is fixedly installed on the hot melt plate at the hot melt head.

[0017] By adopting the above technical solution, the hot melt head dissipates heat when completing the hot melt of the burrs of the injection molded part, and the setting of the heat insulation plate can increase the service life of the hot melt plate.

[0018] Preferably, the support plate has an adjustment groove, and the locking cylinder is fixedly installed with a bolt that matches the adjustment groove, and the bolt is threaded with a nut.

[0019] By adopting the above technical solution, the opening of the adjustment groove facilitates the adjustment of the position of the locking plate relative to the support plate. According to the different sizes of injection molded parts, the position of the locking plate can be adjusted through the adjustment groove, thereby realizing the locking of injection molded parts of different sizes.

[0020] Preferably, a protective cover is fixedly installed on the workbench around the periphery of the hot-melting mechanism.

[0021] By adopting the above technical solution, the protective cover can effectively isolate the spatter and debris generated during the hot-melt process, preventing them from harming operators. It also prevents external impurities from entering the hot-melt area, ensuring a clean and safe processing environment. Furthermore, the protective cover helps reduce noise transmission and improves the comfort of the working environment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Through the cooperation of the clamping mechanism and the hot melt mechanism, the automatic hot melt treatment of the burrs on the injection molded parts can be achieved, which significantly improves processing efficiency, reduces labor intensity, and avoids scratches and dimensional deviations caused by manual operation;

[0024] 2. Under the precise control of the controller, the hot melt head performs hot melt treatment on the burrs, ensuring the consistency and stability of processing, effectively solving problems such as assembly interference and poor sealing, and improving product quality;

[0025] 3. The synergistic effect of the clamping cylinder and the hot melt cylinder ensures stable positioning and precise handling of the injection molded parts during processing, reducing processing errors caused by positional deviation. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0034] This application discloses a burr hot melt device for injection molded parts.

[0035] Reference Figure 1 A hot melt device for injection molded parts includes a worktable 1, on which a hot melt mechanism 2, a transfer mechanism 4 and a transfer mechanism 5 are provided for automatically transferring the injection molded parts between the hot melt mechanism 2 and the transfer mechanism 4 are provided, and a controller for driving each mechanism is also provided.

[0036] Reference Figure 2 and Figure 3The hot melt mechanism 2 includes a clamping mechanism 21 fixedly mounted on the worktable 1. The clamping mechanism 21 includes at least two opposing clamping cylinders 212. A clamping block 213 is fixedly mounted on the piston rod of the clamping cylinder 212, and a buffer pad 2131 is fixedly mounted on the side of the clamping block 213 away from the clamping cylinder 212 to ensure that the injection molded part can be fixed by the clamping cylinder 212, and that the clamping block 213 will not cause wear or other damage to the injection molded part during the clamping process. A support frame 22 is fixedly mounted on the worktable 1 around the clamping mechanism 21. A hot melt plate 24 is slidably mounted on the support frame 22. A hot melt cylinder 23 is fixedly installed at the top of the support frame 22. The piston of the hot melt cylinder 23 is fixedly installed on the hot melt plate 24, thereby controlling the movement of the hot melt plate 24 on the support frame 22. The input end of the hot melt cylinder 23 is electrically connected to the output end of the controller, so that the controller can control the hot melt cylinder 23, thereby controlling parameters such as the moving speed and moving distance of the hot melt plate 24 on the support frame 22. A hot melt head 25 facing the clamping mechanism 21 is fixedly installed on the hot melt plate 24. The input end of the hot melt head 25 is electrically connected to the output end of the controller, so that the controller can control the working state of the hot melt head 25. Furthermore, a heat insulation plate 241 is fixedly installed on the hot melt plate 24 at the position of the hot melt head 25, separating the hot melt head 25 from the hot melt plate 24 to prevent the hot melt plate 24 from being in a high-temperature state continuously, thereby extending the service life of the hot melt plate 24.

[0037] Reference Figure 4 The hot melt mechanism 2 also includes a locking mechanism 3 disposed between the clamping mechanism 21 and the hot melt plate 24. The locking mechanism 3 includes a support plate 31, a locking cylinder 32 and a locking plate 33. The support plate 31 is fixedly installed on the support frame 22, and the locking cylinder 32 is fixedly installed on the free end of the support plate 31. The piston of the locking cylinder 32 is fixedly connected to the locking plate 33, and the movement direction of the locking cylinder 32 is perpendicular to the movement direction of the clamping cylinder 212. The movement directions of the locking cylinder 32 and the clamping cylinder 212 can be perpendicular to each other on the same horizontal plane, so that the locking cylinder 32 and the clamping cylinder 212 correspond to different sides of the injection molded part, thereby completing the clamping of different sides of the injection molded part and enhancing the fixing effect of the injection molded part. Furthermore, the support plate 31 is provided with an adjustment groove 311, and the locking cylinder 32 is fixedly installed with bolts that match the adjustment groove 311. The bolts are threaded with nuts. Through the cooperation of the bolts and nuts, the relative position between the locking cylinder 32 and the support plate 31 can be adjusted and fixed, thereby adapting to the processing of injection molded parts of different sizes. Because after the clamping mechanism 21 fixes the injection molded part, the position of the injection molded part may not be exactly where the hot melt head 25 can remove the burrs in the injection port of the injection molded part. By clamping the injection molded part with the locking mechanism 3 and adjusting and fixing the position of the injection molded part, it is ensured that the hot melt head 25 can accurately and accurately melt the burrs in the injection port of the injection molded part.

[0038] Reference Figure 5 The workbench 1 also includes a transfer mechanism 4 fixedly installed beside the hot melt mechanism 2. The transfer mechanism 4 includes a transfer bracket 41 fixedly installed on the workbench 1. A first transfer cylinder 42 with its movement direction parallel to the top surface of the workbench 1 is fixedly installed on the transfer bracket 41. The piston of the first transfer cylinder 42 is fixedly connected to a second transfer cylinder 43 with its movement direction perpendicular to the top surface of the workbench 1. A transfer head 44 is fixedly installed on the piston of the second transfer cylinder 43. The input ends of the first transfer cylinder 42 and the second transfer cylinder 43 are electrically connected to the output end of the controller, so that the controller can control the working state of the first transfer cylinder 42 and the second transfer cylinder 43, thereby adjusting the distance between the transfer head 44 and the injection molded part. A suction nozzle 45 is fixedly installed on the side of the transfer head 44 near the top surface of the workbench 1. A vacuum pump is fixedly connected to the suction nozzle 45, and the vacuum pump is electrically connected to the controller. The controller controls the working state of the vacuum pump, thereby controlling the working state of the suction nozzle 45 to complete the transfer of the injection molded part.

[0039] Reference Figure 6 The worktable 1 is also equipped with a conveying mechanism 5, which realizes the automatic transfer of injection molded parts between the hot melt mechanism 2 and the transfer mechanism 4. The conveying mechanism 5 includes a conveying track 51 opened on the worktable 1. The clamping mechanism 21 also includes a receiving plate 211. The clamping cylinder 212 is fixedly installed on the receiving plate 211 to fix the injection molded parts on the receiving plate 211. The receiving plate 211 is fixedly connected to the conveying track 51. The way the receiving plate 211 is slidably connected to the conveying track 51 is that the bottom of the receiving plate 211 is connected to the conveying track 51. A slider is fixedly installed at the corresponding position on the track 51. The slider is slidably connected to the conveying track 51, thereby realizing the sliding of the receiving plate 211 on the conveying track 51. A conveying cylinder 52 is fixedly installed on the worktable 1. The piston of the conveying cylinder 52 is fixedly connected to the receiving plate 211. The input end of the conveying cylinder 52 is fixedly connected to the output end of the controller, so that the working state of the conveying cylinder 52 can be controlled by the controller. Thus, the receiving plate 211 is automatically conveyed between the transfer mechanism 4 and the hot melt mechanism 2 under the guidance of the conveying track 51 by the piston.

[0040] Reference Figure 1 A protective cover 6 is fixedly installed on the workbench 1 around the periphery of the hot-melt mechanism 2. The protective cover 6 prevents injury to workers or contamination of the processing environment caused by debris during the hot-melt process of injection molding and the cleaning of milling cutters. To allow observation of the hot-melt process of the injection molding parts by the hot-melt mechanism 2, the protective cover 6 can be configured as a protective frame and a protective glass. The protective frame is fixedly installed on the workbench 1, and the protective glass is fixedly installed on the protective frame, making the hot-melt mechanism 2 transparent to the production environment for easy observation.

[0041] The implementation principle of this application embodiment is as follows:

[0042] When not in use, all components of the burr hot melt device are in their initial positions.

[0043] When processing of injection molded parts is required, the operator places the injection molded part within the clamping space of the clamping cylinder 212 of the receiving plate 211. Then, the controller controls the clamping cylinder 212 to drive the clamping block 213 to fix the injection molded part. After fixing, the transfer cylinder 52 drives the receiving plate 211 and the injection molded part on the receiving plate 211 to the position of the locking plate 33. The controller controls the locking cylinder 32 to drive the locking plate 33 closer to the injection molded part until the locking plate 33 abuts against the injection molded part to achieve injection molding. Further securing the plastic part involves the controller controlling the hot melt cylinder 23 to drive the hot melt plate 24 closer to the injection molded part, allowing the hot melt head 25 on the hot melt plate 24 to extend into the injection port of the injection molded part. The hot melt head 25 is then controlled to melt the burrs on the injection molded part. After melting, the heating state of the hot melt head 25 is turned off, and the hot melt cylinder 23 is driven to remove the hot melt plate 24 from the injection molded part. Simultaneously, the locking cylinder 32 is driven to move the locking plate 33 away from the injection molded part, stopping the locking of the injection molded part. Then, the controller controls the transfer cylinder 52... The receiving plate 211 and the hot-melted injection molded parts on the receiving plate 211 are conveyed to the transfer mechanism 4, and the clamping cylinder is controlled to retract, no longer clamping and fixing the injection molded parts. Then, the controller controls the first moving cylinder and the second moving cylinder to cooperate, so that the suction nozzle 45 on the transfer head 44 is aligned with the injection molded parts, and the suction nozzle 45 is controlled to contact the injection molded parts. At the same time, the vacuum pump is controlled to put the suction nozzle 45 into a negative pressure state to complete the adsorption of the injection molded parts. Then, the first transfer cylinder 42 and the second transfer cylinder 43 are controlled to move the position of the transfer head 44, so that the transfer head 44 transfers the injection molded parts to the storage position of the injection molded parts or the position of the next process. In this embodiment, a conveying mechanism for injection molded parts is provided on the side of the workbench 1. The conveying mechanism is used to convey the processed injection molded parts to the storage position or the next process. The controller controls the first transfer cylinder 42 and the second transfer cylinder 43 to control the transfer head 44 to realize the transfer of the injection molded parts between the receiving plate 211 and the conveying mechanism, thereby automatically completing the hot melting of the burrs of the injection molded parts.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
