Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine feeding equipment, in particular to an injection molding machine feeding device. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] The feeding device of the injection molding machine refers to the accessories or devices used in the feeding process of the injection molding machine to ensure that the raw materials can smoothly enter the feeding barrel of the injection molding machine. Common injection molding machine feeding tooling includes the following: Hopper: used to store raw materials. The capacity and size of the hopper will vary according to different injection molding machine models and production requirements. Automatic feeder: Through wind pressure or mechanical operation, the raw materials are transported into the feeding barrel of the injection molding machine at a certain rate, which improves the feeding speed and accuracy. Heater: Heat the raw materials to the appropriate temperature for injection molding. Different types and models of injection molding machines require different types of heaters. Quantitative feeder: used to control the amount of raw material feed, improve accuracy and production efficiency. Suction device: used to suck raw materials from bags or boxes and transport them to the feeding barrel of the injection molding machine. Delivery pipeline: used to connect various feeding equipment and the feeding barrel of the injection molding machine. The position and length of the pipeline can be adjusted to meet different production needs. Gravity delivery pipeline: The raw materials naturally slide into the feeding barrel of the injection molding machine by gravity, which is suitable for small-scale production. Manual feeding tooling: manually add raw materials into the feeding barrel of the injection molding machine. It is suitable for some small injection molding machines or small single production volume.

[0004] However, the feeding equipment in the prior art, such as hoppers, manual feeding tools, gravity conveying pipe suction devices and conveying pipes, are prone to technical problems such as blockage. Although automatic feeders and heaters can achieve quantitative feeding without blockage, they are too expensive and have complex structures, making them unsuitable for assembly in small injection molding machines. Therefore, there is a need for an injection molding machine feeding device that is low in cost and avoids blockage. Utility Model Content

[0005] The purpose of the utility model is to provide a feeding device for an injection molding machine, so as to solve the problem of a feeding device for an injection molding machine proposed in the above background technology, which can stably feed materials to a small injection molding machine and avoid clogging. The feeding device for an injection molding machine comprises: an external box body, the external box body is provided with a rectangular cavity; a side baffle, the first end of which is hingedly connected to the inner side wall of the external box body, the number of the side baffles is two, and the two side baffles are adapted to the rectangular cavity; an electric telescopic rod, one end of which is hingedly connected to the side baffle, and the other end of which is hingedly connected to the inner side wall of the rectangular cavity, the electric telescopic rod is located below the side baffle, and the electric telescopic rod, the side baffle and the inner wall of the rectangular cavity form a three-link structure.

[0006] Through the above structure, when the utility model encounters a blockage, the staff can start the electric telescopic rod, so that the electric telescopic rod is continuously contracted, increasing the opening area at the bottom of the feeding device, thereby reducing the blockage. When the blockage is serious, the mode of the electric telescopic rod can be adjusted to make the electric telescopic rod continuously extend and shorten, so that the injection plastic blocked inside the utility model moves back and forth, thereby reducing the blockage.

[0007] Furthermore, it also includes a conveying hose, wherein the first end of the conveying hose is sleeved on the two side plates, the first end of the conveying hose is a retractable structure, and the second end of the conveying hose is connected to the feed port of the injection molding machine.

[0008] Furthermore, the second end of the conveying hose is a retractable structure, and the second end of the conveying hose is sleeved on the feed port of the injection molding machine.

[0009] Furthermore, it also includes a processor, which is electrically connected to the electric telescopic rod and is provided with a wireless communication device.

[0010] Furthermore, the processor is electrically connected to a warning light, and the warning light is arranged on the external box.

[0011] Furthermore, the warning light is a warning light strip, and the warning light strip is arranged around the external box.

[0012] Furthermore, a side baffle of the injection molding machine is provided with a gravity sensor, and the gravity sensor is electrically connected to the processor.

[0013] Furthermore, telescopic legs are provided at the bottom of the external box body, the number of the telescopic legs is four, and the four telescopic legs are distributed in a rectangular array.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the injection molding machine forms a feeding funnel through a rectangular cavity and a side baffle, thereby completing the basic function of feeding. When feeding is required, the staff only needs to align the lower end of the device with the feed inlet of the injection molding machine;

[0015] At the same time, the electric telescopic rod, the side baffle and the rectangular cavity form a three-link structure, which can realize the adjustment of the position of the side baffle. When the electric telescopic rod is extended, the side baffle moves away from the rectangular cavity, and the opening of the device is reduced. When the electric telescopic rod is shortened, the side baffle starts to move toward the rectangular cavity, and the opening of the device is increased. When a blockage occurs, the electric telescopic rod is started to shorten to increase the opening size, thereby avoiding the blockage.

[0016] When the blockage is serious and cannot be solved by simply increasing the opening size, the electric telescopic rod can be repeatedly started to make the side baffle move back and forth, so that the blocked injection plastics rub against each other, thereby avoiding blockage.

Figure 1 , Figure 2As shown, the feeding device of the injection molding machine includes: an external box body 1, wherein the external box body 1 is provided with a rectangular cavity 2; the surface of the rectangular cavity 2 is smooth to reduce friction, a side baffle 3, a first end of which is hingedly connected to the inner wall of the external box body 1, and the number of the side baffles 3 is two, and the two side baffles 3 are adapted to the rectangular cavity 2; an electric telescopic rod 4, one end of which is hingedly connected to the side baffle 3, and the other end of which is hingedly connected to the inner wall of the rectangular cavity 2, the electric telescopic rod 4 is located below the side baffle 3, and the electric telescopic rod 4, the side baffle 3 and the inner wall of the rectangular cavity 2 form a three-link structure, wherein the side baffle 3 and the rectangular cavity 2 constitute an injection molding channel, when the side baffle 3 moves with the electric telescopic rod 4, the opening of the injection molding channel also changes accordingly, and when the electric telescopic rod 4 begins to shrink, the opening of the injection molding channel gradually increases, thereby increasing the passing rate of the injection molding channel. Through the above structure, when the utility model encounters a blockage, the staff can start the electric telescopic rod 4, so that the electric telescopic rod 4 is continuously contracted, increasing the opening area at the bottom of the feeding device, thereby reducing the blockage. When the blockage is serious, the mode of the electric telescopic rod 4 can be adjusted to make the electric telescopic rod 4 continuously extend and shorten, so that the injection plastic blocked inside the utility model moves back and forth, thereby reducing the blockage.

[0024] Furthermore, if Figure 2 As shown, in order to better realize the utility model, the injection molding machine feeding device also includes a conveying hose 5, the conveying hose 5, the first end of the conveying hose 5 is sleeved on the two side panels, the first end of the conveying hose 5 is a telescopic structure, the second end of the conveying hose 5 is connected to the injection molding machine feed port, the telescopic structure is an opening made of telescopic material, usually made of rubber material, so that it can change with the change of the length of the electric telescopic rod 4.

[0025] Furthermore, if Figure 2 As shown, the second end of the conveying hose 5 is a retractable structure, and the second end of the conveying hose 5 is sleeved on the feeding port of the injection molding machine. Through the above structure, it can be installed on injection molding machines of different models, so as to complete the feeding of injection molding machines of different models.

[0026] Furthermore, if Figure 2 As shown, it also includes a processor 6, which is electrically connected to the electric telescopic rod 4.
