Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to an injection mold for casting an aluminum bottom tube. Background Art

[0002] In the mold industry, various molds and tools are used to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting, forging, smelting and stamping. In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". Injection molds are needed in the casting process of the aluminum base tube.

[0003] Existing injection molds are usually divided into an upper mold and a lower mold. During use, a certain proportion of liquid raw materials is injected from the injection port of the upper mold. After the injection is completed, it is cooled by an external cooling structure to make it quickly molded. However, the surface of the finished product after production is easy to stick to the inner wall of the lower mold, and external tools are needed to remove the material, which is not only time-consuming and labor-intensive, but also makes it impossible to carry out subsequent injection molding work, reducing work efficiency. If the staff makes mistakes in the process of removing the material, it is also very easy to cause damage to the finished product. Therefore, we provide an injection mold for aluminum bottom barrel casting. Utility Model Content

[0006] By adopting the above scheme, when demolding is required, hold the pull ring on the top of the upper mold and rotate it, drive the upper mold to rotate through the pull ring, drive the threaded column to rotate through the upper mold, until the threaded column is separated from the inner cavity of the thread groove, and after removing the upper mold, start the dual-axis motor, and drive the threaded rod to rotate through the dual-axis motor. Because the threads on the two threaded rods are opposite, when the threaded rod rotates forward or reverse, the two threaded sleeves can be driven to move inward or outward. When the threaded rod rotates forward, the threaded sleeve is driven to move outward through the threaded rod, the connecting column is driven to move outward through the threaded sleeve, and the lower mold is driven to move outward through the connecting column until the two lower molds are separated, and then the formed aluminum cylinder can be removed from the positioning column. By the same token, when the lower mold needs to be reset, the reverse operation can be performed.

[0007] As a preferred embodiment of the injection mold for casting an aluminum bottom tube, a pull ring is fixedly connected to the top of the upper mold, and injection ports are opened on both sides of the top of the upper mold.

[0009] As a preferred embodiment of the injection mold for casting an aluminum bottom tube, a heat dissipation port is provided on the back of the shell, and a dustproof net is provided in the inner cavity of the heat dissipation port.

[0010] By adopting the above solution and setting the heat dissipation port, the heat generated by the dual-axis motor when working can be quickly discharged, thereby achieving the purpose of rapid heat dissipation.

[0011] As a preferred embodiment of the injection mold for casting an aluminum bottom tube, one end of the threaded rod is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the shell.

[0014] By adopting the above scheme, the slide block is limited by setting the slide groove, and the threaded sleeve is assisted to move, thereby preventing the threaded sleeve from rotating.

[0015] As a preferred embodiment of the injection mold for casting an aluminum bottom tube, base plates are fixedly connected to both sides of the bottom of the shell, and a non-slip pad is bonded to the bottom of the base plate.

[0016] By adopting the above solution and providing the anti-skid pad, the device has an anti-skid function, and the stability of the device is further improved.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model drives the threaded rod to rotate through a double-axis motor. Since the threads on the two threaded rods are opposite, when the threaded rod rotates forward or reversely, the two threaded sleeves can be driven to move inward or outward. When the threaded rod rotates forward, the threaded sleeve is driven to move outward by the threaded rod, the connecting column is driven to move outward by the threaded sleeve, and the lower mold is driven to move outward by the connecting column until the two lower molds are separated. The formed aluminum cylinder can be removed from the positioning column. Similarly, when the lower mold needs to be reset, the reverse operation can be performed to achieve the purpose of automatic demoulding, which greatly improves work efficiency.

[0019] 2. The utility model holds the pull ring on the top of the upper mold and rotates it, thereby driving the upper mold to rotate through the pull ring, and driving the threaded column to rotate through the upper mold until the threaded column is separated from the inner cavity of the thread groove, thereby greatly improving the efficiency of removing the upper mold and facilitating subsequent work.

A threaded groove 4 is provided on the top of the positioning column 3. A threaded column 6 is fixedly connected to the bottom of the upper mold 5. A shell 7 is fixedly connected to the bottom of the workbench 1. Figure 3As shown, a heat dissipation port is provided on the back of the shell 7, and a dustproof net is provided in the inner cavity of the heat dissipation port. Through the setting of the heat dissipation port, the heat generated by the dual-axis motor 8 when working is quickly discharged to achieve the purpose of rapid heat dissipation. The dual-axis motor 8 is fixedly installed at the bottom of the inner cavity of the shell 7, and the output ends on both sides of the dual-axis motor 8 are fixedly connected with threaded rods 9. The surface of the threaded rod 9 is threadedly connected with a threaded sleeve 10. The top of the threaded sleeve 10 is fixedly connected with a connecting column 11, and one end of the connecting column 11 is fixedly connected with a lower mold 12. Figure 3 As shown, both sides of the bottom of the inner cavity of the shell 7 are provided with sliding grooves, and the bottom of the threaded sleeve 10 is fixedly connected with a slider, and the bottom of the slider is slidably connected to the inner cavity of the sliding groove. The slider is limited by the setting of the sliding groove to assist the threaded sleeve 10 to move and prevent the threaded sleeve 10 from rotating. When demoulding is required, the pull ring on the top of the upper mold 5 is held and rotated, and the upper mold 5 is driven to rotate by the pull ring, and the threaded column 6 is driven to rotate by the upper mold 5 until the threaded column 6 is separated from the inner cavity of the thread groove 4. After the upper mold 5 is removed, the dual-axis motor 8 is started to rotate through the dual-axis The motor 8 drives the threaded rod 9 to rotate. Since the threads on the two threaded rods 9 are opposite, when the threaded rod 9 rotates forward or reverse, the two threaded sleeves 10 can be driven to move inward or outward. When the threaded rod 9 rotates forward, the threaded sleeve 10 is driven to move outward through the threaded rod 9, and the connecting column 11 is driven to move outward through the threaded sleeve 10. The lower mold 12 is driven to move outward through the connecting column 11 until the two lower molds 12 are separated. The formed aluminum cylinder can be removed from the positioning column 3. By the same token, when the lower mold 12 needs to be reset, the reverse operation can be performed.

[0025] See Figure 1 As shown, a pull ring is fixedly connected to the top of the upper mold 5, and injection ports are opened on both sides of the top of the upper mold 5. The pull ring is used as a leverage point to facilitate the subsequent rotation of the upper mold 5. Figure 3 As shown, one end of the threaded rod 9 is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the housing 7. The setting of the bearing assists the threaded rod 9 to rotate, which greatly improves the smoothness of the threaded rod 9 when working. Figure 1 As shown, base plates are fixedly connected to both sides of the bottom of the shell 7, and anti-skid pads are bonded to the bottom of the base plates. The provision of the anti-skid pads enables the device to have an anti-skid function, further improving the stability of the device.

[0026] When in use, firstly, a certain proportion of liquid raw materials is injected into the inner wall of the lower mold 12 through the injection port at the top of the upper mold 5. After the injection is completed, it is cooled by an external tool to make it quickly molded. When demolding is required, the pull ring at the top of the upper mold 5 is held and rotated, and the upper mold 5 is driven to rotate by the pull ring, and the threaded column 6 is driven to rotate by the upper mold 5 until the threaded column 6 is separated from the inner cavity of the thread groove 4. After the upper mold 5 is removed, the dual-axis motor 8 is started, and the dual-axis motor 8 drives the threaded rod 9 to rotate. Because the threads on the two threaded rods 9 are opposite, when the threaded rod 9 rotates forward or reverse, the two threaded sleeves 10 can be driven to move inward or outward. When the threaded rod 9 rotates forward, the threaded sleeve 10 is driven to move outward by the threaded rod 9, and the connecting column 11 is driven to move outward by the threaded sleeve 10, and the lower mold 12 is driven to move outward by the connecting column 11, until the two lower molds 12 are separated, the formed aluminum cylinder can be removed from the positioning column 3. By the same token, when the lower mold 12 needs to be reset, the reverse operation can be performed.
