Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding machine technology, specifically to a material handling structure for an injection molding machine. Background Technology
[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.
[0003] Chinese utility model patent CN216635258U discloses a telescopic material handling structure for a vertical injection molding machine, including a U-shaped plate. A housing is located below the U-shaped plate, and two grooves are formed on the inner wall of the U-shaped plate. Each groove contains a matching slide bar, and a movable plate is fixedly connected to the side of the two slide bars that are close to each other. This utility model includes a drive motor. The drive motor and a connecting rod work together to cause a connecting gear to move the movable plate via a gear plate. This movable plate then causes the slide bars to slide within the grooves. Simultaneously, a clamping mechanism moves above the injection molded part via the movable plate, and then clamps the injection molded part.
[0004] However, when the material is unloaded after being picked up by the present invention in a vertical injection molding machine, the clamping mechanism needs to be shaken to assist in unloading. This not only increases the wear of the clamping mechanism, but may also cause damage to the clamping mechanism, increasing maintenance costs. In addition, the clamping mechanism requires a vacuum pump to achieve adsorption and demolding, which not only increases equipment costs, but also increases energy consumption. Therefore, a material picking structure for injection molding machines is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a material handling structure for injection molding machines, which has advantages such as high working efficiency and solves the problems mentioned in the background.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A material handling structure for an injection molding machine includes a base, a support fixedly connected to the top of the base, a clamping device disposed on one side of the base, and a moving mechanism disposed on the top of the base. The clamping device is externally provided with an adsorption device for assisting in picking up and placing materials.
[0008] The adsorption device includes an installation tube and a piston cylinder fixedly connected to the outside of the clamping device. Both ends of the installation tube are fixedly connected to corrugated pipes, and the bottom end of the corrugated pipe is fixedly connected to a conical cover. A counterweight is fixedly connected to the outside of the conical cover, and a transmission mechanism extending to the outside of the piston cylinder is provided inside the piston cylinder.
[0009] The transmission mechanism includes a piston block slidably connected inside the piston cylinder and an electric push rod fixedly installed on the top of the clamping device. A piston rod is fixedly connected to the top of the piston block, and a movable plate is fixedly connected between the output end of the electric push rod and the top end of the piston rod.
[0010] Furthermore, there are two sets of the conical cover and the counterweight, and the two sets of the conical cover and the counterweight are symmetrically distributed on the outside of the clamping device.
[0011] Furthermore, the outer diameter of the piston block is adapted to the inner diameter of the piston cylinder, and the piston rod is slidably connected inside the piston cylinder and extends to its upper surface.
[0012] Furthermore, an extraction pipe is fixedly connected between the bottom end of the piston cylinder and the mounting pipe, and an air supply pipe is fixedly connected between one side of the piston cylinder and the mounting pipe. Both the extraction pipe and the air supply pipe are elastically hinged with check valves inside.
[0013] Furthermore, the moving mechanism includes a first linear module fixedly connected to the top of the support base, a first slider slidably connected inside the first linear module, a second linear module disposed on the upper surface of the first slider, a second slider slidably connected inside the second linear module, and a telescopic cylinder fixedly installed on the top of the second slider.
[0014] Furthermore, a mounting plate is fixedly connected to the output end of the telescopic cylinder, and the clamping device is fixedly connected to the outside of the mounting plate.

[0016] Furthermore, the second linear module is fixedly connected to the top of the rotating shaft, and the second linear module is rotatably connected to the top of the support base via the rotating shaft.
[0017] Compared with the prior art, this utility model provides a material handling structure for injection molding machines, which has the following beneficial effects:
[0018] 1. The material handling structure of this injection molding machine uses an electric push rod to drive the piston rod and piston block to slide inside the piston cylinder via a moving plate. When material needs to be discharged, the electric push rod pushes the piston block to slide downwards, and air is delivered to the mounting pipe and conical shroud through the air supply pipe to release the negative pressure. The material can fall smoothly without the need for the clamping equipment to shake, effectively avoiding wear and damage to the clamping equipment and reducing maintenance costs.
[0019] 2. The material handling structure of this injection molding machine is driven by a drive motor, which drives the rotating shaft to rotate through the transmission gear and the driven gear. The second linear module is fixedly connected to the top of the rotating shaft, so it can rotate around the rotating shaft. This allows the clamping device and the adsorption device to rotate and adjust their angles in the horizontal direction. No matter what angle the material is placed at, the rotating mechanism can adjust it to a suitable material handling angle, which enhances the adaptability of the material handling structure to different working conditions.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 4This embodiment of an injection molding machine material handling structure includes a base 1, a support 2 fixedly connected to the top of the base 1, a clamping device 3 disposed on one side of the base 1, and a moving mechanism 4 disposed on the top of the base 1. The clamping device 3 is externally equipped with an adsorption device 5 for assisting in picking up and placing materials. The moving mechanism 4 includes a first linear module 41 fixedly connected to the top of the support 2. A first slider 42 is slidably connected inside the first linear module 41. A second linear module 43 is disposed on the upper surface of the first slider 42. A second slider 44 is slidably connected inside the second linear module 43. A telescopic cylinder 45 is fixedly mounted on the top of the second slider 44. A mounting plate 46 is fixedly connected to the output end of the telescopic cylinder 45, and the clamping device 3 is fixedly connected to the outside of the mounting plate 46. The first linear module 41 and the first slider 42 cooperate to allow the second linear module 43 to move horizontally; the second linear module 43 and the second slider 44 cooperate to achieve vertical movement; the telescopic cylinder 45 can push the mounting plate 46 and the clamping device 3 to extend and retract. This multi-dimensional precision movement enables the clamping device 3 and the adsorption device 5 to be accurately moved to the material discharge position. Combined with the smooth material discharge by the adsorption device 5, the accuracy of material discharge is improved. The first linear module 41 and the second linear module 43 are both conventional technologies known to the public in the prior art, so their specific structural composition and working principle will not be described in detail in this article.
[0027] In this embodiment, the adsorption device 5 includes an installation pipe 51 and a piston cylinder 55 fixedly connected to the outside of the clamping device 3. Both ends of the installation pipe 51 are fixedly connected to corrugated pipes 52, and the bottom end of the corrugated pipes 52 is fixedly connected to a conical cover 53. A counterweight 54 is fixedly connected to the outside of the conical cover 53. A transmission mechanism extending to the outside is provided inside the piston cylinder 55. The transmission mechanism includes a piston block 56 slidably connected inside the piston cylinder 55 and an electric push rod 57 fixedly installed on the top of the clamping device 3. A piston rod 59 is fixedly connected to the top of the piston block 56, and a moving plate 58 is fixedly connected between the output end of the electric push rod 57 and the top end of the piston rod 59. By using the electric push rod 57 as a power source, the piston block 56 is driven to slide inside the piston cylinder 55. Using the extraction pipe 510, the air supply pipe 511, and the internal check valve, a negative pressure is formed to adsorb the material, and air is supplied to release the negative pressure and release the material, thus reducing equipment costs.
[0028] The device comprises two sets of conical shrouds 53 and counterweights 54, symmetrically distributed on the outside of the clamping device 3. When the clamping device 3 moves the adsorption device 5 close to the material, the weight of the counterweights 54 overcomes the elastic resistance of the bellows 52, ensuring the conical shrouds 53 are firmly pressed against the material surface, guaranteeing a tight seal and preventing negative pressure leakage due to insufficient fit, thus ensuring the stability of the adsorption force. For injection molded parts with uneven surfaces or slight curvature, the weight of the counterweights 54, combined with the expansion and contraction characteristics of the bellows 52, allows the conical shrouds 53 to adaptively adjust their angle, maintaining good contact with the material surface at all times. During the movement or rotation of the material handling structure, the equipment may experience slight vibrations. The weight of the counterweights 54 increases the inertia of the conical shrouds 53, reducing the impact of vibration on their contact with the material, preventing instantaneous air leakage due to vibration, and ensuring a stable and reliable adsorption process.
[0029] Specifically, the outer diameter of the piston block 56 is matched with the inner diameter of the piston cylinder 55, and the piston rod 59 is slidably connected inside the piston cylinder 55 and extends to its upper surface.
[0030] It should be noted that an extraction pipe 510 is fixedly connected between the bottom end of the piston cylinder 55 and the mounting pipe 51, and an air supply pipe 511 is fixedly connected between one side of the piston cylinder 55 and the mounting pipe 51. Both the extraction pipe 510 and the air supply pipe 511 are elastically hinged with check valves inside.
[0031] In this embodiment, a rotating mechanism 6 is provided between the first slider 42 and the second linear module 43. The rotating mechanism 6 includes a drive motor 61 fixedly mounted on the top of the first slider 42 and a rotating shaft 63 rotatably connected to the top of the first slider 42. A driven gear 64 is fixedly mounted on the outside of the rotating shaft 63, and a transmission gear 62 meshing with the driven gear 64 is fixedly connected to the output shaft of the drive motor 61. When facing the complex layout of the injection molding machine's working area or materials with various placement methods, the rotating mechanism 6, in conjunction with the moving mechanism 4, eliminates the need to repeatedly adjust the position of the entire material handling structure. A simple combination of rotation and movement allows for quick alignment of the clamping device 3 and the adsorption device 5 with the material, significantly shortening the material handling time and improving overall material handling efficiency.
[0032] The second linear module 43 is fixedly connected to the top of the rotating shaft 63, and the second linear module 43 is rotatably connected to the top of the support base 2 through the rotating shaft 63.
[0033] The working principle of the above embodiments is as follows:
[0034] During operation, the first linear module 41 and the first slider 42 in the moving mechanism 4 cooperate to achieve lateral movement, and the second linear module 43 and the second slider 44 cooperate to achieve longitudinal movement. The telescopic cylinder 45 pushes the mounting plate 46 to drive the clamping device 3 to extend and retract vertically. Combined with the drive motor 61 in the rotating mechanism 6, which drives the rotating shaft 63 to rotate through the transmission gear 62 and the driven gear 64, the clamping device 3 and the adsorption device 5 are precisely delivered to the material picking position. The adsorption device 5 drives the piston block 56 to slide inside the piston cylinder 55 through the electric push rod 57. The negative pressure is formed by the extraction pipe 510, the air supply pipe 511 and the check valve to achieve the conical cover 53. The counterweight block 54 assists in the sealing and adsorption of materials. After picking up the material, it is adjusted to the material discharge position by the moving mechanism 4 and the rotating mechanism 6. Then, the negative pressure is released by the air supply pipe 511, and the clamping device 3 completes the stable material discharge.
