Description

Technical Field

[0001] The utility model relates to the field of screwdriver production, in particular to an adjustable blanking device for an injection molding machine. Background Art

[0002] Injection molding machines, also known as injection molding machines or injection machines, are used to produce screwdriver handles. They are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. They are available in vertical, horizontal, and all-electric models. Injection molding machines heat the plastic and apply high pressure to the molten plastic, forcing it to eject and fill the mold cavity. Injection molding is a cyclic process, with each cycle consisting of: metered feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part removal. After the part is removed, the mold is closed again for the next cycle.

[0003] In actual use, it is found that when adding materials, all the plastic pellets are directly poured into the storage box of the injection molding machine, and then the storage box will stir the plastic pellets. However, in this process, if too much material is added at one time, the stirring effect of the storage box will deteriorate, eventually leading to uneven plasticization. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides an adjustable injection molding machine unloading device. Through the setting of the mechanical structure, it realizes automatic interval unloading and can adjust the amount of unloading each time, thereby solving the common problem in the current technology that the storage box cannot be effectively stirred due to excessive dumping of plastic pellets, which ultimately leads to uneven plasticization.

Through the setting of special-shaped gears and mechanical rotation, the intermittent rotation of the first unloading disc is realized, and the second unloading disc is driven to rotate at the same time. In conjunction with the setting of the disc, the rotary cover is opened at a fixed position to complete the unloading work, and finally the function of intermittent unloading is realized. The rotating handle drives the ring up and down through the transmission of the mechanical structure, and finally drives the second disc up and down, thereby realizing the function of adjusting the unloading amount each time. By changing the position of the adjusting cylinder, the size of the unloading space formed by the unloading cylinder and the adjusting cylinder is changed, thereby changing the unloading amount each time.

[0006] Furthermore, a rectangular mounting plate is provided in the shell, a support frame is provided on the shell, and two slide grooves are provided inside the shell; the long axis passes through the rectangular mounting plate in the shell and is rotatably arranged.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 5As shown, the adjustable injection molding machine blanking device described in the utility model includes a housing 1, a motor 2 fixed in the housing 1, a rotating shaft 3 provided on the motor 2, a special-shaped gear 4 fixed on the rotating shaft 3, a long shaft 5 that passes through and rotates on the housing 1, a driving gear 6 fixed at the bottom of the long shaft 5 and engaged with the special-shaped gear 4, a first blanking tray 7 fixed at the top of the long shaft 5, two blanking barrels 8 fixed on the first blanking tray 7, a sleeve shaft 9 slidably sleeved on the long shaft 5, and a shaft fixed at The second unloading tray 10 on the sleeve 9, two adjusting cylinders 11 fixed on the second unloading tray 10, two rotating covers 12 respectively rotatably arranged on the two adjusting cylinders 11, a ring 13 rotatably sleeved on the sleeve 9, a rack 14 fixed on the ring 13, a disc 15 fixed on the rack 14, an adjusting rod 16 that penetrates and rotates on the outer shell 1, an adjusting gear 17 fixed on one end of the adjusting rod 16, a handle 18 fixed on the other end of the adjusting rod 16, and a unloading funnel 19 fixed on the outer shell 1.When in use, pour plastic pellets into the discharge funnel, start the motor, the motor drives the rotating shaft to rotate, thereby driving the special-shaped gear to rotate, the protruding teeth on the special-shaped gear are distributed in an arc shape, the protruding teeth on the special-shaped gear are engaged with the driving gear, when the special-shaped gear rotates, its protruding teeth contact the teeth on the driving gear, driving the driving gear to rotate, when the special-shaped gear rotates a certain angle, its protruding teeth are separated from the teeth on the driving gear, at this time the special-shaped gear continues to rotate without driving the driving gear to rotate, thereby realizing the intermittent rotation of the special-shaped gear driving the driving gear, when the special-shaped gear drives the driving gear to rotate When the gear shifts, the gear shifts from one end of the hopper to the other, and the other end of the hopper moves in a circular motion relative to the first feeding tray. When the gear shifts, the gear shifts from one end of the hopper to the other, and the hopper shifts in a circular motion relative to the first feeding tray. The two adjusting cylinders are also driven to make interval circular motion with the long axis as the center, driving the second unloading disc and the sleeve to make the same motion. According to the setting of the ring, when the sleeve rotates, the ring, the rack and the disc will not rotate. In order to limit the movement trend of the ring, the rack and the disc, the two convex plates on the rack are located in the chute. At this time, the chute plays a role of limiting. According to the rotation position of the two adjusting cylinders, the rotary cover will rotate. Since the plastic particles always exert downward pressure on the rotary cover, the rotary cover always has a tendency to rotate under the action of pressure and its own gravity. When the convex plates at the rear end of the rotary cover are When the rotary cover comes into direct contact with the disc, the rotary cover will open, allowing the plastic pellets to fall. At this time, the discharge barrel is in the discharge position, which is fixed. When the protrusion at the rear end of the rotary cover collides with the protrusion on the disc, the protrusion on the disc acts as a limit block to ensure that the rotary cover remains horizontal and the plastic pellets do not fall. They are always in the discharge space formed by the discharge barrel and the adjustment barrel. In summary, this device can effectively realize the function of intermittent discharge, avoiding the problem of ineffective stirring of the storage box of the injection molding machine due to excessive one-time dumping of plastic pellets, which ultimately leads to uneven plasticization. When it is necessary to adjust the amount of material being discharged each time, turn the handle, which in turn drives the adjusting rod to rotate, and then drives the adjusting gear to rotate, thereby driving the rack to move up and down. Since the convex plate on the rack is located in the groove of the outer shell, the groove acts as a guide groove. By changing the position of the rack, the disc and the ring are driven up and down at the same time, thereby driving the sleeve shaft up and down, and then driving the second discharge disc up and down, and finally driving the two adjusting cylinders to move up and down, thereby changing the size of the discharge space formed by the discharge barrel and the adjusting barrel, and finally realizing the function of changing the discharge amount.
