Description

Technical Field

[0001] The utility model belongs to the technical field related to injection molding and punching, and particularly relates to a laser automatic gate cutting component. Background Art

[0002] Injection molding is a method of producing industrial products. Products are usually made of rubber and plastics. In the existing production process, most products need to go through the processes of runner punching, cavity placement, gate repair, etc. after injection molding. Therefore, in the runner punching process, the corresponding punching gate components are needed.

[0003] However, when using the existing punching gate assembly, most of them use the traditional mechanical punching method to punch the injection molded structure, but this method cannot guarantee the gate punching accuracy, gate quality, and gate flatness, and requires manual trimming of the gate. At the same time, when using the existing punching gate assembly, since it does not have the function of pre-pressing and carrying the injection molded structure, after each punching, the injection molded structure needs to be carried manually, which reduces the punching efficiency. To this end, we provide a laser automatic gate cutting assembly to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a laser automatic gate cutting component, which drives the punching positioning fixture to the lower position of the laser frame through the punching cylinder, so as to quickly punch the injection molded structure and improve the punching accuracy and efficiency. At the same time, the up and down movement and adsorption function of the pneumatic suction device can pre-press the injection molded structure and carry the injection molded structure after punching.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a laser automatic gate cutting component, comprising a base plate and a mounting plate fixed at the rear portion of the left side of the base plate; a punching cylinder is fixed at the rear portion of the upper end surface of the base plate, a pneumatic suction device is arranged at a position located above and in front of the punching cylinder, a punching positioning fixture is arranged at the front portion of the upper end surface of the base plate, a work station block fixedly connected to the piston end of the punching cylinder is fixed at the lower end surface of the punching positioning fixture, L-shaped plates located at the left and right sides of the base plate are arranged at the left and right portions below the pneumatic suction device, a baffle is arranged directly behind the base plate, a transplanting cylinder is fixed at the left and right portions of the front end surface of the baffle, an electric lifting frame is fixed to the upper end surface of the mounting plate, and a laser frame is arranged at a position in front of the electric lifting frame.

[0007] The utility model is further configured that a limiting plate connected with the front end surface of the station block is fixed on the front end surface of the bottom plate, and positioning rods are fixed on the left and right parts between the punching cylinder and the limiting plate.

[0008] The utility model is further configured that a through positioning hole is opened at the front end surface of the work station block at a position corresponding to the positioning rod, and the positioning rod slides through the inner position of the positioning hole consistent with the front and rear positions.

[0009] The utility model is further configured that a connecting block is fixed at a position of the inner side wall of the L-shaped plate corresponding to the position of the transplanting cylinder, and the connecting block is fixedly connected to the piston end of the transplanting cylinder.

[0015] When the utility model is in use, the injection molding structure is placed on the upper end surface of the punching and cutting positioning fixture, and the punching and cutting cylinder is controlled to retract, thereby driving the punching and cutting positioning fixture to move to a position directly below the pneumatic clamp. At this time, the laser frame is controlled to work, so the laser frame will perform punching and cutting on the connection of the injection molding structure, thereby achieving automatic punching and cutting of the gate position of the injection molding structure, ensuring the gate punching and cutting accuracy, and making the punching and cutting gate position of the injection molding structure flat without the need for trimming.

[0016] When the utility model is in use, after the punching and positioning fixture moves the rod to the position directly below the pneumatic gripper, the pneumatic gripper is controlled to work, thereby the pneumatic gripper adsorbs the injection molded structure, and then the transfer cylinder is controlled to work, and the transfer cylinder controls the pneumatic gripper to move the punched injection molded structure to the rear position of the punching and cutting cylinder, thereby achieving pre-pressing and transporting of the injection molded structure and improving the punching and cutting efficiency.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0027] See also Figure 1-5The utility model is a laser automatic gate cutting component, which drives the punching positioning fixture 7 to the lower position of the laser frame 4 through the punching cylinder 101, so as to quickly punch the injection molded structure and improve the punching accuracy. At the same time, the up and down movement and adsorption function of the pneumatic suction device 6 can pre-press the injection molded structure and carry the injection molded structure after punching.

[0028] Specifically, a base plate 1 and a mounting plate 2 fixed to the rear portion of the left side of the base plate 1; a punching cylinder 101 is fixed to the rear portion of the upper end surface of the base plate 1, a pneumatic gripper 6 is provided at a position above and in front of the punching cylinder 101, a punching positioning fixture 7 is provided at the front portion of the upper end surface of the base plate 1, a work block 701 fixedly connected to the piston end of the punching cylinder 101 is fixed to the lower end surface of the punching positioning fixture 7, L-shaped plates 601 located on the left and right sides of the base plate 1 are provided on the left and right portions below the pneumatic gripper 6, a baffle plate 8 is provided directly behind the base plate 1, a transplanting cylinder 802 is fixed to the left and right portions of the front end surface of the baffle plate 8, an electric lifting frame 3 is fixed to the upper end surface of the mounting plate 2, and a laser frame 4 is provided in front of the electric lifting frame 3.

[0029] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when the injection molded structure needs to be punched, the injection molded structure can be placed on the upper end surface of the punching positioning fixture 7, and the punching cylinder 101 is controlled to retract, thereby driving the punching positioning fixture 7 to move to the position directly below the pneumatic fixture 6. At this time, the pneumatic fixture moves downward to pre-press the injection molded structure. At this time, the laser frame 4 is controlled to work, so the laser frame 4 will punch the connection of the injection molded structure. At the same time, the pneumatic fixture 6 is controlled to work, so that the pneumatic fixture 6 will adsorb the injection molded structure, and then the transfer cylinder 802 is controlled to work. The transfer cylinder 802 will control the pneumatic fixture 6 to move the punched injection molded structure to the rear position of the punching cylinder 101, and stop adsorption when controlling the pneumatic fixture 6, thereby loosening the punched injection molded structure and making it fall, and the transfer cylinder 802 and the punching cylinder 101 are controlled to reset to the initial position. Specific embodiment 2

[0030] See also Figure 2 , 3 5. Based on the specific embodiment 1, the positioning rod 103 passes through the inner position of the positioning hole 702 and is limited by the limiting plate 102, so as to ensure that the moving direction of the working block is limited.

[0031] Specifically, a limit plate 102 connected to the front end surface of the work block 701 is fixed to the front end surface of the base plate 1, and positioning rods 103 are fixed to the left and right parts between the punching cylinder 101 and the limit plate 102. A through positioning hole 702 is opened at the position of the front end surface of the work block 701 corresponding to the positioning rod 103. The positioning rod 103 slides through the internal position of the positioning hole 702 consistent with the front and rear positions. A tripod 301 is fixed to the lower end surface of the laser frame 4, and the tripod 301 is fixedly connected to the lifting end of the electric lifting frame 3. A focusing tube 5 is fixed to the end of the laser frame 4, and the focusing tube 5 is located directly above the pneumatic clamp 6.

[0032] The operation process of this embodiment is as follows: when the punching cylinder 101 is working, the punching cylinder 101 will drive the work block 701 to slide on the upper end surface of the base plate 1, and at the same time, the positioning rod 103 passes through the internal position of the positioning hole 702, so that the positioning rod 103 limits the work block 701. At the same time, after the punching cylinder 101 is reset, the limiting plate 102 on the front end surface of the base plate 1 limits the work block 701, so that the moving distance of the work block 701 is limited. At the same time, when the laser frame 4 is working, the focusing tube 5 is used to focus the laser frame 4 to ensure that the laser frame 4 can punch accurately. Specific embodiment three

[0033] See also Figure 2 , 4 On the basis of the first specific embodiment, the slide block 604 is supported by the slide rail 801 to support the L-shaped plate 601, so that the L-shaped plate 601 can stably drive the pneumatic gripper 6 to move.

[0034] Specifically, a connecting block 605 is fixed at the position of the inner wall of the L-shaped plate 601 corresponding to the position of the transplanting cylinder 802, and the connecting block 605 is fixedly connected to the piston end of the transplanting cylinder 802, and a slide rail 801 is fixed to the front end surface of the baffle 8 directly below the transplanting cylinder 802, and a slider 604 slidably mounted on the circumferential side of the slide rail 801 is fixed to the lower end surface of the L-shaped plate 601, and a pre-stressing cylinder 602 is fixed to the other side of the L-shaped plate 601 opposite to the connecting block 605, and a connecting plate 603 is fixed to the piston end of the pre-stressing cylinder 602, and the connecting plate 603 is spirally connected to the end of the pneumatic gripper 6 by bolts.

[0035] The operation process of this embodiment is as follows: when it is necessary to control the pneumatic gripper 6 to move up and down, the pre-pressure cylinder 602 can be controlled to work, thereby the pre-pressure cylinder 602 will drive the pneumatic gripper 6 to move up and down, and then the pneumatic gripper 6 can be moved to connect with the upper end surface of the punching and positioning fixture 7. At the same time, when the L-shaped plate 601 is driven by the transfer cylinder 802, the L-shaped plate 601 will slide along the slide rail 801 through the slider 604, so the slide rail 801 supports the slider 604, and thereby supports the L-shaped plate 601, so that the L-shaped plate 601 can stably drive the pneumatic gripper 6 to move.
