Abstract
Description
Technical Field
[0001] The utility model relates to the field of extrusion moulds, in particular to a one-mold two-cavity extrusion mould for making an aluminum-wood door frame. Background Art
[0002] Aluminum-wood door frame. In modern home design, aluminum-wood door has gradually become the first choice of many families with its unique material and elegant appearance. It not only has a beautiful appearance, but also has excellent durability and practicality, which brings more convenience and comfort to home life. When making aluminum-wood door frame, the extruder is often used to heat and extrude wood-plastic material into the extrusion mold to achieve the extrusion molding effect, thereby obtaining the product. The extrusion mold is a mold used for plastic processing. The molten plastic material is molded into the desired shape through the extrusion process. According to the purpose and structure of the mold, the plastic extrusion mold can be divided into many types, such as pipe extrusion mold, plate extrusion mold, profile extrusion mold, etc. At the same time, there are not only one-mold-one-out molds but also one-mold-two-out molds, which can effectively improve production efficiency.
[0003] At present, the existing one-mold two-cavity extrusion mold core for making aluminum-wood door frames is not provided with an extrusion port, a feed port, a discharge port, an arc block and a convex block. Therefore, during extrusion, the melt is usually directly extruded onto the mold core through an extruder and finally pushed into the extrusion cavity for molding by pressure. There are no extrusion ports, arc blocks and convex blocks to gather the melt and accelerate the flow of the melt, which may easily cause part of the melt to fail to enter the extrusion cavity smoothly, resulting in low internal melt density and uneven melt in the two extrusion cavities, thereby resulting in poor quality of the aluminum-wood door frame. At the same time, there is no feed port and a discharge port. Blocks formed during the production process of the aluminum-wood door frame will block part of the melt from outside, thereby reducing the efficiency and density of the melt entering the extrusion cavity, greatly reducing the practicality of the one-mold two-cavity extrusion mold for making aluminum-wood door frames, thereby reducing the durability of the aluminum-wood door frame products. Summary of the invention
[0004] The main purpose of the utility model is to solve the problem that the existing one-mold two-cavity extrusion mold for the production of aluminum-wood door frames does not have the function of gathering the melt and improving the efficiency and density of the melt entering the extrusion cavity. Therefore, it is easy to cause uneven melt and low density in the extrusion cavity during production, thereby reducing the practicality and product durability of the one-mold two-cavity mold, and provide a one-mold two-cavity extrusion mold for the production of aluminum-wood door frames.
[0005] The specific scheme of the utility model is: a one-mold two-cavity extrusion mold for making aluminum-wood door frames, including a mold main body, an extrusion port is provided on the surface of the mold main body, the extrusion port is in a square cone shape and the inner wall is arranged in an arc surface, the end of the extrusion port with a smaller diameter is connected to two extrusion cavities, a mold core is provided inside the two extrusion cavities, a feed port is provided on the top of the mold core, a convex block is provided inside the feed port and is located on one side of the feed port, discharge ports connected to the feed port are respectively provided on both sides of the convex block, the two discharge ports are connected to the extrusion cavity away from one end of the feed port, a partition block is provided between the two extrusion cavities, and an arc block is provided on the top of the partition block.
[0006] According to the above technical scheme, the square tapered extrusion port can effectively gather the melt inside and finally accelerate the flow of the melt through the arc block, thereby improving the uniformity of the melt entering the extrusion cavity and avoiding the internal vacuum of the aluminum-wood door frame in the single cavity, which makes the aluminum-wood door frame weak and reduces the durability and practicality of the product.
[0007] Furthermore, the arc angle of the arc block is 5°~10°.
[0008] According to the above technical solution, by setting the angle between 5° and 10°, the fluidity of the molten material when entering the extrusion port can be improved, thereby improving the uniformity and efficiency of the molten material entering the extrusion cavity, and further improving the durability of the product and the practicality of the mold.
[0009] Furthermore, the feed port is rectangular in shape, and is connected to the discharge port in a herringbone shape.
[0010] According to the above technical scheme, the feed port is set in a rectangular shape to correspond to the shape of the extrusion port above it, thereby improving the feeding efficiency. At the same time, when the feed port and the discharge port are connected, the shape is a herringbone, which can effectively discharge the molten material entering the feed port to the extrusion cavities on both sides.
[0011] Furthermore, the top of the protrusion is arranged in an arc surface.
[0012] According to the above technical solution, the curved surface of the top of the protrusion can effectively improve the fluidity of the melt in the feed port, thereby improving the efficiency of discharging from the discharge port, making the density of the melt in the extrusion cavity higher, and further improving product quality and durability.
[0013] Compared with the prior art, the utility model has the following advantages: the one-mold two-cavity extrusion mold for the production of aluminum-wood door frames is equipped with an extrusion port, a feed port, a discharge port, an arc block and a convex block, which can effectively improve the fluidity of the melt, thereby ensuring the uniformity of the melt in the two extrusion cavities, ensuring the consistency of the quality of the samples in the two extrusion cavities, and at the same time achieving the effect of filling the melt from the middle through the feed port and the discharge port, thereby improving the density of the melt in the extrusion cavity, further improving the quality of the aluminum-wood door frame products, and greatly improving the practicality and durability of the one-mold two-cavity extrusion mold for the production of aluminum-wood door frames.

[0019] See also Figure 1-4, the present embodiment is a one-mold two-cavity extrusion mold for making an aluminum-wood door frame, which is composed of a mold core 1 and a mold body 2. The mold body 2 is a one-mold two-cavity extrusion mold for making an aluminum-wood door frame as a whole. An extrusion port 3 is provided on the surface of the mold body 2. The extrusion port 3 is in a square cone shape. The inner wall of the extrusion port 3 is provided with an arc surface. The arc surface improves the fluidity of the molten material. The extrusion port 3 is connected to two extrusion cavities 4 at one end with a smaller diameter, that is, the discharge end. A mold core 1 is provided inside the two extrusion cavities 4. The mold core 1 is used to form the internal core structure of the aluminum-wood door frame product to assist in forming a hollow shape in the middle of the aluminum-wood door frame when making the aluminum-wood door frame. When the molten material enters the extrusion cavity 4, the mold core 1 can prevent the middle part of the extrusion cavity 4 from solidifying to achieve the effect of a rectangular cavity, thereby forming the effect of an aluminum-wood door frame. The mold core 1 can be fixed to the mold core 1 at one end through a connecting rod 5 and fixed to the inner wall of the extrusion cavity 4 at the other end, or fixed by other means. A feed port 6 is provided on the top of the mold core 1. The feed port 6 is used to enter the molten material to achieve the effect of multiple feeding. A convex block 7 is provided inside the feed port 6 and on one side thereof which is parallel to the feed port 6. The convex block 7 is used to guide the molten material so that the molten material is discharged from the discharge ports 8 on both sides of the convex block 7. Discharge ports 8 which are respectively connected to the feed port 6 and the extrusion cavity 4 are provided on both sides of the convex block 7, so as to achieve the effect of further filling the molten material in the extrusion cavity 4. A partition block 9 is provided between the two extrusion cavities 4. The partition block 9 is integrally formed with the mold body 2. The partition block 9 is used to separate the products in the two extrusion cavities 4 so as to achieve the effect of one out of two. An arc block 10 is integrally formed on the top of the partition block 9. The arc block 10 is located on one side of the middle part of the extrusion port 3. The arc block 10 can improve the fluidity of the molten material extruded from the extrusion port 3 on one side, thereby improving the efficiency of the molten material entering the extrusion cavities 4 on both sides, and further improving the uniformity of the molten material in the extrusion cavity 4.
[0020] Furthermore, the arc angle of the arc block 10 is 5° to 10°, thereby improving the fluidity of the melt and enhancing the uniformity of the melt in the extrusion cavities 4 on both sides.
[0021] Furthermore, the feed port 6 is rectangular in shape and corresponds to the square in shape of the extrusion port 3, thereby improving the feeding efficiency. When the extrusion port 3 is feeding, the feed port 6 is connected with the discharge end of the extrusion port 3 and can feed directly. At the same time, the feed port 6 is connected with the discharge port 8 in a herringbone shape, which is convenient for discharging the molten material into the extrusion cavities 4 on both sides.
[0022] Furthermore, the top of the protrusion 7 is arranged in an arc surface, which improves the fluidity of the internal melt after the material is fed through the feed port 6, thereby improving the uniformity and efficiency of the discharge from the discharge ports 8 on both sides.
[0023] The working principle of this embodiment is as follows: when the one-mold two-cavity extrusion mold for aluminum-wood door frame production starts working, the molten material first enters through the extrusion port 3. After the molten material enters the extrusion port 3, the fluidity can be improved by the arc surface of the inner wall. Then part of the molten material enters the extrusion cavity 4 and the feed port 6. When the molten material enters the feed port 6, it contacts the protrusion 7. Since the top of the protrusion 7 is provided with an arc surface, the fluidity of the internal molten material is improved, thereby improving the discharge efficiency and uniformity of the discharge ports 8 on both sides. When the discharge ports 8 on both sides extrude the molten material, the molten material can be further filled from the inside of the extrusion port 3. The density of the melt in the extrusion port 3 is improved, thereby improving the production quality and efficiency. At the same time, when the melt enters the extrusion port 3, it will flow downward and contact the arc block 10 on the partition block 9. Since the arc block 10 is provided with an arc, the fluidity of the melt can be improved, so that the melt can flow into the extrusion cavity 4 on both sides. Finally, the melt is extruded through the bottom of the extrusion cavity 4 to achieve the effect of product molding, thereby improving the uniformity of the melt in the two extrusion cavities 4 and the product quality, greatly improving the practicality of the one-mold two-cavity extrusion mold for the production of aluminum-wood door frames and the durability of aluminum-wood door frame products.
