Description

Technical Field

[0001] This utility model relates to the field of pressurized feeding, and in particular to a special pressurized feeding device. Background Technology

[0002] In molding processes such as injection molding and die casting, the shape of the mold cavity is often quite complex, including various thin-walled parts, deep holes, and undercut structures. If there is not enough pressure to push the material into the mold, the material may not be able to completely fill these complex areas, resulting in short-shot phenomenon in the product. For example, when injection molding a plastic gear with a fine internal structure, without a pressurized feeding device, the plastic melt may only fill the outer contour of the gear and cannot enter the internal structure such as the tooth groove, making the product not meet the design requirements. The pressurized feeding device can provide enough power to overcome the resistance of the melt in the flow process, ensuring that the material can fill the entire mold cavity evenly and completely, thereby producing products with accurate dimensions and complete shape.

[0003] In material handling and molding processes, traditional pressurized feeding devices cannot provide a stable pressurized environment, resulting in uneven material filling or material shortages. In addition, the existing design may limit the operator's ability to adjust the discharge rate and position according to actual needs, making it difficult to observe the material status in the barrel in real time and hindering timely adjustments. When the material is injected into the mold through the material gun, uneven distribution may occur, affecting product quality and consistency.

[0004] Therefore, it is necessary to provide a new special pressurized feeding device to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a special pressurized feeding device comprising: a barrel body, a head, a discharge assembly, and a molding assembly. The discharge assembly is located inside the barrel body. A stainless steel filter screen is clamped between the top of the barrel body and the bottom of the head. The top of the barrel body and the bottom of the head are connected by multiple bolts. The four sides of the discharge assembly are fixedly connected to the inner wall of the bottom of the barrel body. The molding assembly and the discharge assembly are connected by multiple feeding hoses.

[0007] The discharge assembly includes a discharge turntable, a discharge base, and multiple discharge connectors. The bottom of the discharge turntable and the top of the discharge connectors are in close contact with each other, and the discharge turntable and the discharge base are rotatably connected by a rotating arm. Multiple equidistant discharge holes are opened on the surfaces of the discharge turntable and the discharge base, and the tops of the multiple discharge connectors are respectively located inside the multiple discharge holes. The bottom ends of the multiple discharge connectors are respectively interference-fitted to one end of the multiple feeding hoses.

[0008] Preferably, the top of the end cap is provided with a vent valve, and the bottom end of the vent valve is connected to the top of the end cap in an internal threaded manner. The outer surface of the end cap is provided with a pressure angle seat valve and a suction ball valve, and both the pressure angle seat valve and the suction ball valve are connected to the interior of the end cap in an internal threaded manner.

[0009] Preferably, a feeding ball valve and an observation component are arranged sequentially from top to bottom on one side of the barrel. The end of the feeding ball valve connected to the barrel is in communication with the inside of the barrel and is internally threaded. The observation component is bolted to one side of the barrel.

[0010] Preferably, the observation assembly includes a sight glass flange and a sight glass, the sight glass flange being clamped between the sight glass and the barrel body, and the sight glass being connected to the surface of the barrel body by bolts.

[0013] Preferably, the stainless steel filter screen has multiple filter holes equidistantly arranged around its inner surface.

[0014] Compared with related technologies, the special pressurized feeding device provided by this utility model has the following beneficial effects:

[0015] When pressurizing and feeding material into the mold, the material is replenished to the barrel through the suction angle seat and the material ball valve via the feeding fan. When feeding material into the mold, the barrel is first pre-pressurized through the pressurized air pipe and the pressurized angle seat valve to ensure the stability of the pressure during processing, enabling a fast and full feeding process and avoiding material shortages. The discharge cylinder pushes the rotating arm to rotate the discharge turntable, which, together with the feeding hose, quickly pumps the material in the barrel into the mold cavity, ensuring the flexibility and accuracy of the discharge and precise control of the product weight. In addition, the observation component allows operators to observe the internal condition of the barrel at any time and make timely adjustments. The interference fit between multiple material guns and the feeding hose ensures that the material is injected evenly into the mold, improving the quality and consistency of the product.

[0038] The working principle provided by this utility model is as follows:

[0039] When pressurizing and feeding material into mold 16, firstly, a feeding fan is used to feed material into barrel 1 through suction angle seat and material hopper pipe via feeding ball valve 7, ensuring that barrel 1 has sufficient material preparation. When mold 16 needs to be filled with material, a certain pre-pressure is applied to barrel 1 through pressurized air pipe via pressurized angle seat valve 4. This step ensures that material can be injected into mold 16 at a faster speed and higher efficiency during actual feeding. Then, discharge cylinder 14 pushes rotating arm 13 to rotate discharge turntable 10. At this time, the material inside barrel 1 will be quickly fed into mold cavity of mold 16 through feeding hose 15 under preset pressure. The pressurized feeding process is completed through the mutual linkage and cooperation between the above-mentioned device components.
