Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, and more specifically to an automatic injection molding feeding mechanism. 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 materials. Injection molding machines can be divided into vertical, horizontal and vertical-horizontal composite types according to the arrangement of the injection device and the clamping device. The feed inlet of existing injection molding machines is often high, and manual feeding is currently mostly used, which is laborious to operate.

[0003] For example, patent application number CN201921324298.6 injection molding automatic feeding mechanism includes a box body, a hydraulic cylinder, a push plate, a load-bearing plate, a support arm, a material placement groove, a first elastic support member, a second elastic support member, a limit rod bracket and a limit rod. When feeding the injection molding machine, the raw material barrel can be placed in the material placement groove, and the hydraulic cylinder is used to push the push plate upward, thereby driving the load-bearing plate to rise. When the extension part at the end of the material placement groove moves to the bottom of the limit rod, the material placement groove rotates relative to the support arm, and the material placement groove is tilted with one end higher than the other end, so as to pour the raw material in the raw material barrel in the material placement groove into the feed port of the injection molding machine. After loading, the hydraulic cylinder drives the load-bearing plate to descend, and the material placement groove returns to the center. The structure is simple, and the operator can place the raw material barrel into the material placement groove at a low position, effectively reducing the work intensity of the operator.

[0004] This structure uses a hydraulic cylinder to drive the load-bearing plate to move vertically, and uses a hinged connection to tilt the material placement slot during the rising process to complete the tilting of the raw material barrel and thus complete the loading. However, the inclination angle of the material placement slot of this structure is limited, resulting in limited inclination of the raw material barrel, resulting in low loading efficiency and incomplete loading. At the same time, the structure lacks stabilizing components, which will cause instability during the vertical movement process. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4 In the utility model, an injection molding automatic feeding mechanism comprises a feeding base 1, a lifting push rod 2 is fixedly installed on the top of the feeding base 1, a bearing plate 3 is fixedly connected to the top of the lifting push rod 2, a guide frame 4 is slidably connected to the right side of the feeding base 1, and positioning holes 5 arranged at equal distances are provided on the front and back sides of the feeding base 1. The guide frame 4 is connected to the positioning holes 5 by bolts, and two guide grooves 6 are provided on the inner side of the guide frame 4. A movable plate 7 is provided on the top of the bearing plate 3, and a clamping seat 8 is installed on the top of the movable plate 7. A guide column 9 is fixedly connected to the right side of the movable plate 7, and the two ends of the guide column 9 are respectively located inside the two guide grooves 6 and are slidably connected to the inner wall of the guide groove 6. A rubber roller 10 is rotatably connected to the top of the bearing plate 3, and the top of the rubber roller 10 contacts and is slidably connected to the bottom of the movable plate 7, and a limited position component 11 is provided on the top of the bearing plate 3.

[0024] The limiting assembly 11 includes an electromagnetic seat 1101, which is installed on the top of the supporting plate 3. A metal plate 1102 is connected to the bottom of the movable plate 7. The metal plate 1102 is located on the top of the electromagnetic seat 1101 and is magnetically connected to the electromagnetic seat 1101. A sensor 1103 is installed on the inner wall of the guide groove 6. A processor 1104 is installed on the loading base 1. The electromagnetic seat 1101 and the sensor 1103 are both connected to the processor 1104 signal.

[0025] A limiting groove 15 is provided at the bottom of the movable plate 7 , and the metal plate 1102 is slidably connected inside the limiting groove 15 . A damping pad 16 is connected to the top of the bearing plate 3 , and the electromagnetic seat 1101 is installed on the top of the damping pad 16 .

[0026] When feeding the injection molding machine, the raw material barrel can be placed inside the clamping seat 8 on the top of the movable plate 7 to limit the raw material barrel. At this time, the electromagnetic seat 1101 is energized to generate magnetism to attract the metal plate 1102 on the top, thereby improving the stability of the movable plate 7. Then the lifting push rod 2 drives the supporting plate 3 to move upward. The limiting assembly 11 and the rubber roller 10 on the top of the supporting plate 3 support the movable plate 7. At this time, the guide column 9 is located inside the guide groove 6 inside the guide frame 4. As the lifting push rod 2 continues to move, the guide column 9 contacts the sensor 1103 inside the guide groove 6. The sensor 1103 triggers the signal to be transmitted to the processor 1104. After receiving the signal, the processor 1104 controls the electromagnetic seat 1101 to close the current, so that the electromagnetic seat 1101 loses its magnetism, and then when the lifting push rod 2 continues to move upward, the movable plate 7 is restricted by the guide column 9. The entire upward movement starts to stop, and the rubber roller 10 pushes upward, which will push the right part of the movable plate 7 upward and drive the movable plate 7 to tilt to the right, so that the raw material inside the raw material barrel is poured into the injection molding machine to complete the loading. At this time, the rubber roller 10 is in contact with the movable plate 7, and the user controls the lifting push rod 2 to drive the load-bearing plate 3 to move downward. At this time, the rubber roller 10 gradually moves downward, and the movable plate 7 is always in contact with the rubber roller 10 until the movable plate 7 is in a horizontal state. After that, the guide column 9 begins to move downward in the guide groove 6, and the sensor 1103 is triggered at this time, and the processor 1104 controls the electromagnetic seat 1101 to energize to attract the metal plate 1102, thereby completing the limiting of the movable plate 7 until it is fully reset and can be loaded again. In actual use, the user can change the height of the positioning hole 5 by unscrewing the screw, and thus can load injection molding machines of different heights.

[0027] In the utility model, a guide frame 4 with adjustable height is provided to limit the movable plate 7, so that the movable plate 7 will automatically tilt after moving to the set height to complete the loading of injection molding machines at different heights, and the large rotation range can complete efficient and fast loading. At the same time, a sensor 1103 is provided to automatically control the opening and closing of the limit assembly 11, and automatic opening and closing is achieved while maintaining the stability of the movable plate 7 and the raw materials to coordinate the equipment process, thereby reducing the steps required for personnel to operate.

[0028] See also Figure 1 , wherein: a control panel 12 is installed on the loading base 1 , and the lifting push rod 2 and the limiting component 11 are both electrically connected to the control panel 12 .

[0029] In the present invention, the setting of the control panel 12 allows the user to operate the device more simply and quickly, thereby reducing the steps required for the user to operate and improving the efficiency of feeding the injection molding machine.

[0030] See also Figure 3 , wherein: a slide groove 13 is provided on the front and back of the loading base 1 , and the guide frame 4 is slidably connected to the inner wall of the slide groove 13 .

[0031] In the utility model, when the guide frame 4 moves vertically, the slide groove 13 can play a limiting effect, so that the guide frame 4 is always located on the loading base 1 to maintain stable movement in the vertical direction.

[0032] See also Figure 4 , wherein: a buzzer 14 is installed on the loading base 1, and the buzzer 14 is connected to the processor 1104 by signal.

[0033] In the present invention, when the guide column 9 contacts the sensor 1103, the processor 1104 controls the buzzer 14 to operate, and the buzzer 14 generates a buzzing sound to prompt nearby personnel, so that users can understand the equipment process and status in time.
