Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding mechanism 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] Currently, injection molding machines mostly use nozzles for injection. To maintain the purity of the raw materials, filters are often added inside the nozzles. After a period of use, these filters are prone to clogging, requiring workers to replace the nozzles. This replacement process necessitates a prolonged shutdown of the injection molding machine to unclog the nozzles, increasing the inconvenience for workers and increasing the risk of burns. Furthermore, prolonged shutdowns can cause the molding solution in the injection tube to cool and solidify, thus affecting the injection molding efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an injection mechanism for injection molding machines, which solves the problem of manual replacement of nozzles after they become clogged in traditional injection molding machine mechanisms. This avoids the need to stop the injection molding machine during the replacement process, prevents workers from being scalded by the injection solution, and also prevents the injection solution inside the injection tube from cooling and solidifying, thus preventing any impact on the injection molding efficiency of the injection molding machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection molding mechanism for an injection molding machine, comprising an injection tube, a base fixedly connected to the lower part of the injection tube, a groove formed on the lower surface of one end of the base, a slider slidably connected inside the groove, an L-shaped plate fixedly connected to the lower surface of the slider, a rotating shaft rotatably connected to one side surface of the L-shaped plate, an adjustment component provided on the side surface of the rotating shaft, a support plate fixedly connected to one end of the rotating shaft, nozzles symmetrically provided at both ends of the support plate, and one side surface of one end of the nozzle threadedly connected to the support plate via a threaded connection.

[0006] Preferably, one end of the injection molding tube is fixedly connected to an installation tube, which is aligned with the support plate.

[0007] Preferably, the support plate is internally threaded with a filter screen cylinder, one end of which is fixedly connected to an installation head. One end of the installation head is inserted into the installation tube, and a convex ring is fixedly connected to the inner side wall of the installation tube, with the convex ring and the installation head fitting together.

[0008] Preferably, the outer side of the mounting tube is threaded with a bolt, one end of which passes through the mounting tube and rests on the side surface of the mounting head.

[0009] Preferably, the adjustment assembly includes a worm gear, a worm is meshed with the side surface of the worm gear, a motor is fixedly connected to one end of the worm, and the lower end of the motor is fixedly connected to the upper surface of the L-shaped plate.

[0010] Preferably, a positioning plate is provided on the other side of the L-shaped plate. The upper end of the positioning plate is fixedly connected to the lower surface of the base. A lead screw is threaded into the internal part of the positioning plate. A servo motor is fixedly connected to one end of the lead screw. The side surface of the servo motor is slidably connected to the lower surface of the base. The other end of the lead screw is rotatably connected to the other side surface of the L-shaped plate.

[0011] This utility model provides an injection molding mechanism for an injection molding machine. Compared with the prior art, it has the following advantages: the support plate fixedly connected to one end of the rotating shaft and the nozzles symmetrically installed at both ends of the support plate, the L-shaped plate below the base and the adjustment component connected to the inner surface of the L-shaped plate via the rotating shaft, and the lead screw, positioning plate and servo motor rotatably connected to the other side surface of the L-shaped plate cooperate with each other, thereby solving the problem of manual replacement of nozzles after clogging in traditional injection molding machine mechanisms, avoiding the need to stop the injection molding machine during the replacement process, and preventing workers from being scalded by the injection solution.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an injection molding mechanism for an injection molding machine, including an injection tube 1, a base 2 fixedly connected to the lower part of the injection tube 1, a groove 202 opened on the lower surface of one end of the base 2, a slider 203 slidably connected inside the groove 202, an L-shaped plate 201 fixedly connected to the lower surface of the slider 203, a rotating shaft 207 rotatably connected to one side surface of the L-shaped plate 201, an adjustment component provided on the side surface of the rotating shaft 207, a support plate 3 fixedly connected to one end of the rotating shaft 207, nozzles 301 symmetrically provided at both ends of the support plate 3, a threaded connection 302 connecting one side surface of the nozzle 301 to the support plate 3, and an installation tube 101 fixedly connected to one end of the injection tube 1, the installation tube 101 being aligned with the support plate 3.

[0019] As a technical optimization of this utility model, the internal thread of the support plate 3 is connected to a filter screen cylinder 304, one end of the filter screen cylinder 304 is fixedly connected to an installation head 303, one end of the installation head 303 is inserted into the inside of the installation tube 101, the inner side wall of the installation tube 101 is fixedly connected to a convex ring 103, the convex ring 103 and the installation head 303 fit together, the outer side of the installation tube 101 is threadedly connected to a bolt 102, one end of the bolt 102 passes through the installation tube 101 and abuts against the side surface of the installation head 303. Through the convex ring 103, the installation head 303 and the bolt 102, the support plate 3 can be more firmly installed at one end of the injection tube 1.

[0020] As a technical optimization of this utility model, the adjustment component includes a worm gear 206, a worm 205 meshing with the side surface of the worm gear 206, a motor 204 fixedly connected to one end of the worm 205, and the lower end of the motor 204 fixedly connected to the upper surface of the L-shaped plate 201. The adjustment mechanism can drive the support plate 3 to rotate, thus facilitating the replacement of the nozzle 301 and saving the time of replacing the nozzle 301.

[0021] As a technical optimization of this utility model, a positioning plate 402 is provided on the other side of the L-shaped plate 201. The upper end of the positioning plate 402 is fixedly connected to the lower surface of the base 2. A lead screw 401 is threadedly connected inside the positioning plate 402. A servo motor 4 is fixedly connected to one end of the lead screw 401. The side surface of the servo motor 4 is slidably connected to the lower surface of the base 2. The other end of the lead screw 401 is rotatably connected to the other side surface of the L-shaped plate 201. The servo motor 4, the lead screw 401 and the lead screw 401 can push the base 2 to move, so that when the nozzle 301 is blocked inside, the nozzle 301 can be pushed to disengage from the mounting tube 101.

[0022] When this utility model is in use, if the nozzle 301 becomes clogged, the operator first rotates the bolt 102 on the side surface of the mounting tube 101. This loosens the mounting head 303 at one end of the nozzle 301. Then, the servo motor 4 is started, driving the lead screw 401 to rotate. The lead screw 401 will then move closer to the base 2, and the servo motor 4 will move along with it, pushing the base 2. The base 2, through the rotating shaft 207, pushes the support plate 3 away from one end of the injection molding tube 1. At this point, one end of the nozzle 301 will detach from the mounting tube 101. Then, the operator starts the adjustment... The motor 204 in the joint mechanism drives the worm gear 205 to rotate. At this time, the worm gear 205 drives the rotating shaft 207 to rotate through the worm wheel 206. When the rotating shaft 207 rotates 180 degrees, the motor 204 stops. At this time, the nozzle 301 at the lower end of the support plate 3 is aligned with the mounting tube 101. Then, the servo motor 4 is started to rotate in the opposite direction. Therefore, the servo motor 4 will pull the base 2 back to its original position through the lead screw 401 and the positioning plate 402. Therefore, the new nozzle 301 at the other end of the support plate 3 will be inserted into the interior of the mounting tube 101. Then, the new nozzle 301 is tightened by rotating the bolt 102.
