Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and more specifically, to an injection molding shoe production device. Background Technology

[0002] In the injection molding process of shoes, both injection molding machines and rotary injection molding machines are used. The injection molding machine has a retractable injection head, while the rotary injection molding machine has multiple injection molds that can rotate in a circle. When any injection mold moves to the alignment position with the injection head, the injection head extends until it aligns with the injection port of the corresponding mold. At this point, the injection molding machine injects material into the mold. After injection, the injection head retracts and returns to its original position. The rotary injection molding machine then aligns the next mold with the injection head and repeats the process. Throughout the injection molding process, whenever the injection head separates from the mold, a significant amount of plastic material remains on the outer end of the injection head. This plastic material is in a colloidal state and adheres to the injection head. Over time, this accumulates, requiring constant manual cleaning and reducing injection efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an injection molding shoe production device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an injection molding shoe production device, comprising an injection molding machine and a rotary machine, wherein a rotary motor is correspondingly arranged on one side of the injection head of the injection molding machine, the rotary motor is fixed on the outer shell of the injection molding machine, the rotary motor is arranged parallel to the extension and retraction direction of the injection head of the injection molding machine, one end of the output shaft of the rotary motor is arranged facing the rotary machine, and a plurality of mounting seats are fixedly installed circumferentially at the end of the output shaft of the rotary motor, each mounting seat having a through groove, a scraper inserted in the through groove, one side of the scraper facing the injection molding machine, the scraper being extended and retracted along the depth direction of the through groove and connected to the mounting seat, and a drive module is arranged between the rotary motor and the rotary machine, the drive module being used to drive the scraper to perform extension and retraction movement on the mounting seat.

[0005] As a preferred embodiment of this utility model, each of the mounting bases is equipped with an electric heating device.

[0006] As a preferred embodiment of this utility model, a connecting plate is fixedly installed on the side of the scraper away from the injection molding machine, and the inner side of the connecting plate is connected to the mounting base by a number of elastic elements.

[0007] As a preferred technical solution of this utility model, the drive module includes a cylinder and a magnet. The cylinder is arranged parallel to the rotary motor, and the output end of the cylinder is arranged facing the injection molding machine. The cylinder is fixed to the housing of the injection molding machine by a bracket. A magnet is fixedly installed on the output end of the cylinder. The connecting plate is made of ferromagnetic material, and the connecting plate and the magnet attract each other.

[0008] As a preferred embodiment of this utility model, the magnet is elongated and strip-shaped.

[0009] As a preferred embodiment of this utility model, a scraper is provided on each side of the scraper facing the injection molding machine on the mounting base, and the cross-section of the scraper is triangular.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By incorporating multiple retractable scrapers driven by a rotary motor and equipped with a driver, after the injection head completes one injection cycle, the rotary motor drives the scrapers to perform a circular motion. As the scraper passes the front end of the injection head, it removes any residual plastic material. When the scraper continues to move to the drive module, the drive module drives the scraper to extend and retract on the mounting base. During this extension and retraction, the scraper continuously scrapes against the side of the through groove on the mounting base, removing any remaining material. This self-cleaning process ensures effective scraping and eliminates the need for manual cleaning of the injection head, thus improving injection efficiency. Attached Figure Description

[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] like Figures 1 to 4 As shown, this utility model provides an injection molding shoe production device, including an injection molding machine 1 and a rotary machine 2. A rotary motor 5 is correspondingly arranged on one side of the injection head 3 of the injection molding machine 1. The rotary motor 5 is fixed on the outer shell of the injection molding machine 1 and is arranged parallel to the extension and retraction direction of the injection head 3 of the injection molding machine 1. One end of the output shaft of the rotary motor 5 is arranged facing the rotary machine 2. Several mounting seats 6 are fixedly installed circumferentially at the end of the output shaft of the rotary motor 5. Each mounting seat 6 has a through groove, and a scraper 7 is inserted in the through groove. The blade side of the scraper 7 is arranged facing the injection molding machine 1. The scraper 7 is extended and retracted on the mounting seat 6 along the depth direction of the through groove. A drive module is arranged between the rotary motor 5 and the rotary machine 2. The drive module is used to drive the scraper 7 to perform extension and retraction movement on the mounting seat 6. When the injection head 3 is extending and retracting, the rotary motor 5 drives the scraper 7 to a position that does not obstruct the extension and retraction of the injection head 3. After the injection head 3 completes one extension and retraction injection and reset, the injection head 3 moves to the same plane as the blade of the scraper 7, so that the blade of the scraper 7 can scrape the outer end of the injection head 3.

[0019] Each mounting base 6 is equipped with an electric heating device. The electric heating device is a heating wire, and each heating wire is connected to the power supply through a rotary power supply device, so that while the rotary motor 5 drives the mounting base 6 to rotate, the power supply can synchronously supply power to each heating wire. The function of the electric heating device is to heat the mounting base 6 and the scraper 7 on it, so that the plastic residue on the scraper 7 can remain in a molten state at high temperature, thereby preventing it from solidifying on the scraper 7, making it easier to scrape off the residual plastic material when the scraper 7 extends and retracts.

[0020] A connecting plate 11 is fixedly installed on the side of the scraper 7 away from the injection molding machine 1. The inner side of the connecting plate 11 is connected to the mounting base 6 by several elastic elements 12.

[0021] The drive module includes a cylinder 8 and a magnet 9. The cylinder 8 is parallel to the rotary motor 5, and its output end faces the injection molding machine 1. The cylinder 8 is fixed to the housing of the injection molding machine 1 by a bracket 10. The magnet 9 is fixedly installed on the output end of the cylinder 8. The connecting plate 11 is made of ferromagnetic material, and the connecting plate 11 and the magnet 9 attract each other. When the drive module is in use, the cylinder 8 is operated to continuously perform reciprocating extension and retraction movements, so that the magnet 9 moves synchronously. Thus, whenever the rotary motor 5 drives multiple scrapers 7 to move in front of it in sequence, the magnet 9 attracts the connecting plate 11 to move outward when it approaches the connecting plate 11. The connecting plate 11 drives the scraper 7 to move outward, so that the body of the scraper 7 extends into the through groove. At the same time as it enters the through groove, the mounting base 6 pushes the plastic of the scraper 7 body against the scraper 7 body. When the magnet 9 moves away from the connecting plate 11, the connecting plate 11 automatically resets under the action of its elastic element 12, thereby allowing the scraper 7 to reset. While driving the scraper 7, the drive module has no rigid connection structure with the scraper 7 body, so that it will not block the normal movement of the rotary motor 5 driving the scraper 7, and the movement of the rotary motor 5 will not be hindered.

[0022] The magnet is 9 long and thin.

[0023] On the mounting base 6, a scraper 13 is provided on each side of the scraper 7 facing the injection molding machine 1. The cross-section of the scraper 13 is triangular. The two scraper 13 can improve the removal effect of the mounting base 6 on the residual adhesive on the scraper 7.

[0024] In use, the injection head 3 on the injection molding machine 1 moves toward the mold 4 on the disc machine 2 until it inserts into the injection port of the mold 4. Then, the injection molding machine 1 injects plastic material into the mold 4. After injection, the injection head 3 on the injection molding machine 1 resets. After resetting, the rotary motor 5 is started, driving the scraper 7 to rotate. When the scraper 7 passes the front end of the injection head 3, it scrapes off any residual plastic material. When the scraper 7 continues to move to the drive module, the drive module drives the scraper 7 to extend and retract on the mounting base 6. During this extension and retraction, the scraper 7 continuously scrapes against the side of the through groove on the mounting base 6, removing any residual material. This self-cleaning process ensures effective scraping and eliminates the need for manual cleaning of the injection head 3 during the entire injection process, thus improving injection efficiency.
