Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and particularly relates to an injection mold with a core-pulling function. Background Technique

[0002] An injection mold is a mold used for injection molding and is an indispensable and important part of the injection molding process. It consists of a mold cavity and a mold base. The mold cavity is a part of the injection mold, and its shape and size determine the shape and size of the final plastic product. The mold cavity can be designed into various shapes according to needs, such as flat plates, circles, squares, complex curves, etc. The mold cavity is usually made of steel or aluminum and has high strength and wear resistance. The mold base is the supporting part of the injection mold, which is used to install, fix, and adjust the mold. The mold base is usually machined by a machine tool and has good rigidity and stability.

[0003] However, the existing injection molds do not have the effect of core-pulling during use. Therefore, when the injection mold is used for injection molding of bottles, pipes, containers, etc., a core-pulling operation is required to form a hollow structure with the plastic material. If the injection mold does not perform core-pulling during the injection molding of bottles, pipes, containers, etc., it will lead to increased material consumption, reduced part quality, and production efficiency. Content of the Utility Model

During the core-pulling process, the limiting rod 6910 can slide along with the sliding direction of the core-pulling shaft 610, thereby driving the clamping rod 698 to slide to the right inside the hinge block one 693. The movable assembly 6 includes: a motor 61, a threaded rod 62, a sliding plate 63, a fixed block 64, a sliding block 65, a limiting shaft 66, a connecting plate 67, a fixed shaft 68, and a core-pulling shaft 610.

[0025] The motor 61 is fixedly installed on the top of the chassis 1. A threaded rod 62 is fixedly installed on the surface of the output shaft of the motor 61. A slide plate 63 is threadedly connected to the surface of the threaded rod 62. A fixed block 64 is fixedly installed on the top of the telescopic cylinder 2. A sliding block 65 is slidably connected inside the fixed block 64. The sliding block 65 is fixedly installed at the bottom of the slide plate 63. A limiting shaft 66 is fixedly installed on the right side of the sliding block 65. A connecting plate 67 is fixedly installed on the right side of the limiting shaft 66. A fixed shaft 68 is fixedly installed at the bottom of the connecting plate 67. The core-pulling shaft 610 is slidably connected inside the fixed shaft 68. The core-pulling shaft 610 is fixedly installed on the right side of the slide plate 63. When the clamping rod 698 slides to the right, it will drive the clamping block 699 to fit on the surface of the core-pulling shaft 610 for fixation, thereby improving the stability and practicability of the core-pulling shaft 610 during operation. A clamping member 69 for enhancing the stability during the core-pulling process of the injection mold is further provided inside the movable assembly 6.

[0026] The clamping member 69 includes: a fixed frame 691, which is fixedly installed on the outside of the chassis 1. A first positioning block 692 is fixedly installed on the inner side of the fixed frame 691. A first hinge block 693 is hinged inside the first positioning block 692. A fixed rod 694 is fixedly installed on the inner side of the first hinge block 693. A second hinge block 695 is fixedly installed on the inner side of the fixed rod 694. One end of a fixed spring 696 is fixedly installed on the surface of the second hinge block 695, and the other end of the fixed spring 696 is fixedly installed on the inner side of the first hinge block 693. A second positioning block 697 is fixedly installed on the outside of the fixed block 64. The second hinge block 695 is hinged inside the second positioning block 697. A clamping rod 698 is hinged on the top of the first positioning block 692. A clamping block 699 is hinged on the inner side of the clamping rod 698. A limiting rod 6910 is hinged on the bottom of the clamping rod 698, and the limiting rod 6910 is hinged on the top of the core-pulling shaft 610. When the clamping rod 698 slides, it will also drive the clamping block 699 to fit on the surface of the core-pulling shaft 610 to fix the pulled-out core-pulling shaft 610, thereby preventing the core-pulling shaft 610 from damaging the formed mold inside the injection mold due to the working vibration of the injection molding machine during the pulling-out process, improving the stability of the core-pulling shaft 610 during use and the protection strength for the formed mold, and enhancing the work convenience. Two groups of clamping members 69 are provided, and the two groups of clamping members 69 are symmetrically arranged with the center point of the fixed block 64 as the axis of symmetry. A chute 640 is formed on the surface of the fixed block 64, which can drive the sliding block 65 to slide inside the fixed block 64.

[0027] When the injection mold is in use, the mold two 5 can be driven by the telescopic cylinder 2 to slide to the right on the surface of the slide bar 3. When the mold two 5 slides into the mold one 4 and works, and when core pulling is performed on the inside of the mold one 4 and the mold two 5, the rotation of the threaded rod 62 can be driven by starting the motor 61. When the threaded rod 62 rotates, the slide plate 63 will be driven to slide to the right. When the slide plate 63 slides to the right, the sliding block 65 will be driven to slide inside the fixed block 64. Thus, when the sliding block 65 slides, the limiting shaft 66 and the connecting plate 67 will be driven to slide to the right. Thus, when the connecting plate 67 slides to the right, the core pulling shaft 610 will be driven to slide to the right inside the fixed shaft 68, and then penetrate the inside of the mold one 4 and the mold two 5 for core pulling. During the core pulling process, the limiting rod 6910 can slide along with the sliding direction of the core pulling shaft 610, thereby driving the clamping rod 698 to slide to the right inside the hinge block one 693. When the clamping rod 698 slides to the right, the clamping block 699 will be driven to fit on the surface of the core pulling shaft 610 for fixation, thereby improving the stability and practicality of the core pulling shaft 610 during operation.

[0028] When core pulling operation is performed on the inside of the mold one 4 and the mold two 5, the core pulling shaft 610 can be driven by the motor 61 to slide to the left. When the core pulling shaft 610 slides to the left, the limiting rod 6910 will be driven to slide to the left. When the limiting rod 6910 slides to the left, the clamping rod 698 will be driven to slide to the left inside the hinge block one 693, thereby driving the fixed rod 694 and the hinge block two 695 to slide to the left inside the positioning block two 697. When the clamping rod 698 slides, it will also drive the clamping block 699 to fit on the surface of the core pulling shaft 610 to fix the pulled-out core pulling shaft 610, thereby preventing the core pulling shaft 610 from damaging the formed mold inside the injection mold due to the working vibration of the injection molding machine during the pulling-out process, improving the stability of the core pulling shaft 610 during use and the protection strength for the formed mold, and enhancing the work convenience.
