Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold with self-lubricating function. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. During the use of a mold, there is relative movement between the various parts, such as the opening and closing of the mold, the ejection and retraction of ejector pins, etc. Therefore, it is necessary to add lubricant to the mold. The lubricant can fill between the surfaces of these relatively moving parts to form a lubricating film, separating the metal surfaces, thereby reducing direct contact and friction between metals, reducing wear and extending the service life of the mold.

[0003] During injection molding, the fluid injection material fills the mold cavity of the fixed mold. When the mold cavity has holes or channels for injecting lubricating oil, the injection material can easily flow into it, causing blockage of the channels and making the workpiece not conform to the intended shape, resulting in reduced processing quality. Utility Model Content

[0004] The main purpose of this utility model is to provide a mold with a self-lubricating function, which can effectively solve the problem that when the fluid injection molding material fills the mold cavity of the fixed mold during injection molding, and when the mold cavity is provided with holes or channels for injecting lubricating oil, the injection molding material is easy to flow into it, causing the channels to become blocked, and the workpiece is likely to not conform to the intended production shape, resulting in a reduction in processing quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows: A mold with self-lubricating function includes a fixed mold, a mold cavity, an oil outlet pipe, an oil storage component, and a sealing component; The mold cavity is located at the top of the fixed mold; The oil storage component is disposed inside the fixed mold; The oil outlet pipe is located inside the mold cavity and is fitted to the inner wall of the mold cavity; The sealing component is located inside the oil outlet pipe.

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0012] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0013] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0014] This application designs a mold with self-lubricating function, as shown in the attached figure. Figure 1-4 As shown, it includes a fixed mold 1, a mold cavity 2, an oil outlet pipe 4, an oil storage assembly, and a sealing assembly; Cavity 2 is located at the top of fixed mold 1; The oil storage assembly is located inside the fixed mold 1; The oil outlet pipe 4 is located inside the mold cavity 2 and fits against the inner wall of the mold cavity 2, so that the mold cavity 2 can maintain the original shape of the workpiece. The sealing component is located inside the oil outlet pipe 4.

[0015] Preferably, the closure assembly includes a collar 6, a limiting ring 7, a closing plate 8, a telescopic rod 9, a limiting sleeve 10, and a limiting slide rod 11; The collar 6 is fixedly connected inside the oil outlet pipe 4, and the limiting ring 7 is fixedly connected inside the collar 6, with the limiting ring 7 flush with the inner wall of the mold cavity 2. The sealing plate 8 is movably connected to the inner side of the limiting ring 7. The sealing plate 8 is a semi-circle with a diameter larger than the inner diameter of the limiting ring 7. The movable end of the telescopic rod 9 is fixedly connected to the closed plate 8. The telescopic rod 9 is located inside the closed plate 8. The telescopic end and the fixed end of the telescopic rod 9 are elastically connected. The principle of spring or metal sheet can be used, so it will not be described in detail here. This allows the telescopic end of the telescopic rod 9 to return to its original position after the external force is lost. The limiting sleeve 10 is fixedly connected to the side of the fixed end of the telescopic rod 9. The limiting slide rod 11 is movably connected to the limiting sleeve 10. The limiting slide rod 11 is fixedly connected to the inner wall of the collar 6. The limiting slide rod 11 and the limiting sleeve 10 enable the telescopic rod 9 to move only radially, preventing the telescopic rod 9 from deviating from its movement trajectory and causing the sealing plate 8 to fail to open and close normally.

[0016] Preferably, the oil storage assembly includes an oil injection pipe 3, an oil collection ring 5, a one-way valve disc 12, and a two-way valve disc 13; The oil collecting ring 5 is installed inside the fixed mold 1, and the outer end of the oil outlet pipe 4 extends into the inside of the oil collecting ring 5. The oil injection pipe 3 is fixedly connected to the top of the oil collection ring 5, and the top end of the oil injection pipe 3 extends through to the top of the fixed mold 1; One-way valve disc 12 and one-way valve disc 23 are arranged in a ring inside the oil outlet pipe 4. The outer ends of one-way valve disc 12 and one-way valve disc 23 are fixedly connected to the inner end of the collar 6. The outer side of one-way valve disc 12 is rotatably connected to the fixed end of the telescopic rod 9. One-way valve disc 12 and one-way valve disc 23 can only be opened to the outside by the force of the lubricant flow.

[0017] Working principle: Lubricant is injected into the oil injection pipe 3. The lubricant flows into the oil collecting ring 5 and flows evenly into the oil outlet pipe 4 through the oil collecting ring 5. The flow force of the lubricant pushes open the one-way valve disc 12 and the one-way valve disc 13. During the outward opening process, the one-way valve disc 12 drives the telescopic rod 9 to move radially. The telescopic rod 9 opens the sealing plate 8, so that the lubricant flows into the mold cavity 2. After the injection is completed, the telescopic end of the telescopic rod 9 returns to its original position and drives the one-way valve disc 12, the one-way valve disc 13 and the sealing plate 8 to close, thereby closing the oil outlet pipe 4 and preventing the fluid injection molding material from entering the oil outlet pipe 4 during the injection molding process.

[0018] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
