Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment and discloses a feeding device for an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. When using injection molding, a loading device is required to pour the material into the injection mold.

[0003] The patent authorization publication number is CN212045698U, which discloses a feeding device for an injection molding machine, including a hopper, a feed chamber is provided inside the hopper, a fan is fixedly connected to the top of the hopper, a heating device is fixedly connected to the inside of the fan, and an air guide is fixedly connected to the bottom of the fan and extends to the inside of the feed chamber. Although the above patent can prevent excessive addition of materials from causing blockage of the discharge port by providing a stirring rod, a second rotating motor and a rotating shaft, when using this device, since the height of the hopper cannot be adjusted and the hopper itself is relatively high, the feed port is relatively high. When adding materials to the hopper, it is necessary to manually add materials to the material barrel with the help of tools such as stools, which affects the speed of adding and loading.

[0004] Therefore, a feeding device for an injection molding machine that can adjust the height is needed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: A feeding device for an injection molding machine, see Figures 1-4 , includes a support frame 1 and a storage bin 6, a storage bin 6 is slidably provided on the support frame 1, a first motor 3 is provided on the top left side of the support frame 1 by bolt connection, the output shaft of the first motor 3 is connected to the screw 4 through a coupling, the screw 4 is threadedly provided with a connecting block 401, and the guide rod 5 is slidably provided with a connecting block 401, and the two connecting blocks 401 are both connected to the storage bin 6, and four moving wheels are provided at the bottom of the support frame 1. The moving wheels reduce the friction between the support frame 1 and the ground, thereby facilitating the movement of the support frame 1, and a protective shell 18 is provided on the support frame 1 by bolt connection. The first motor 3 is located inside the protective shell 18, thereby protecting the first motor 3 and preventing foreign matter from entering the first motor 3.

[0029] When it is necessary to use this device, push the support frame 1, and the moving wheel 2 rotates to drive the support frame 1 to move, and then move the support frame 1 to the appropriate position, and then turn on the first motor 3, and the output shaft of the first motor 3 rotates to drive the screw 4 to rotate, so that the connecting block 401 drives the storage bin 6 to move downward, and then adjust the height of the storage bin 6. After the storage bin 6 is adjusted to the appropriate height, pour the material into the storage bin 6, and then control the first motor 3 output shaft to reverse to make the screw 4 rotate, and then make the connecting block 401 drive the storage bin 6 to move upward, so that the bottom of the storage bin 6 is located above the injection molding machine, so that it is convenient to adjust the height of the storage bin 6 according to use needs, and thus facilitate adding and loading.

[0030] Example 2: Based on Example 1, please refer to Figure 3 and Figure 6 A fixing frame 7 is provided inside the storage bin 6 by means of bolt connection, and a second motor 8 is provided in the middle of the fixing frame 7 by means of bolt connection. The output shaft of the second motor 8 is connected to a connecting rod 9 by a coupling, and a scraper 10 is provided on the connecting rod 9. The scraper 10 contacts the inner wall of the storage bin 6, and a cleaning wipe 19 is embedded on the scraper 10. The cleaning wipe 19 is made of rubber, which has a soft texture and good wear resistance, thereby avoiding wear of the inner wall of the storage bin 6 caused by long-term use of the scraper 10 and extending the service life of the cleaning wipe 19.

[0031] When adding material to the injection molding machine, the second motor 8 is turned on, and the output shaft of the second motor 8 rotates to drive the connecting rod 9 to rotate, so that the scraper 10 scrapes off the material remaining on the inner wall of the storage bin 6, thereby avoiding waste caused by material remaining on the inner wall of the storage bin 6.

[0032] See also Figure 1 and Figure 4 , the front and rear sides of the storage bin 6 are both provided with positioning frames 11 by means of bolt connections, a connecting frame 12 is slidingly provided on the positioning frame 11, a baffle 13 is fixedly connected to the lower end of the connecting frame 12, the baffle 13 is in contact with the bottom of the storage bin 6, an elastic member 14 is sleeved on the connecting frame 12, and the two ends of the elastic member 14 are respectively connected to the positioning frame 11 and the connecting frame 12, and the contact surface between the connecting frame 12 and the scraper 10 is an inclined surface, so that the scraper 10 can squeeze the connecting frame 12 and move to the side away from each other.

[0033] When the connecting rod 9 drives the scraper 10 to rotate, the scraper 10 squeezes the connecting frame 12 to move away from each other, and the elastic member 14 is compressed accordingly, so that the connecting frame 12 drives the baffle 13 to move away from each other, thereby opening the storage bin 6 and allowing the material to fall into the injection molding machine. When the scraper 10 no longer squeezes the connecting frame 12, the elastic member 14 returns to its original state, causing the connecting frame 12 to drive the baffle 13 to move toward the side close to each other, closing the storage bin 6, thereby achieving the purpose of intermittent unloading, thereby avoiding clogging the injection molding machine feed port due to excessive addition of material.

[0034] See also Figure 5 A support plate 15 is provided on the top of the storage bin 6, and a mounting seat 16 is fixedly connected to the support plate 15. A connecting seat 1601 is rotatably provided on the mounting seat 16, and a material blocking plate 17 is provided on the connecting seat 1601. A handle is fixedly connected to the material blocking plate 17, and the handle increases the fulcrum between the hand and the material blocking plate 17, thereby facilitating the rotation of the material blocking plate 17.

[0035] When it is necessary to pour the material into the storage bin 6, the material blocking plate 17 is rotated upward to open the storage bin 6, and then the material is poured into the storage bin 6. After the pouring is completed, the material blocking plate 17 is rotated downward to close the storage bin 6, thereby preventing foreign matter from falling into the storage bin 6 and affecting the quality of the injection molded product.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
