Description

Technical Field

[0001] This utility model relates to the field of mold-related products, specifically an injection mold for a tablet computer shell. Background Technology

[0002] A tablet computer is a small, lightweight personal computer that uses a touchscreen as its primary input device. It typically lacks a keyboard, relying instead on a stylus or digital pen for operation. Input can also be made through built-in handwriting recognition, an on-screen keyboard, voice recognition, or a physical keyboard (if the model is equipped with one). The biggest advantage of a tablet computer is its portability. Compared to traditional laptops, tablets are thinner and lighter, making them easier to carry. This allows users to work, study, and enjoy entertainment anytime, anywhere.

[0003] Existing tablet computer casings are manufactured by injection molding using molds. During injection molding, the parts are formed inside the mold cavity. After molding, demolding is required, but during demolding, the formed workpiece may get stuck in the mold cavity and be difficult to remove. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for a tablet computer casing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tablet computer shell injection mold, including an installation plate, a fixed mold above the installation plate, a mold cavity on the fixed mold, the fixed mold being fixed above the installation plate by two symmetrically arranged upright plates, a through opening at the bottom of the mold cavity, a bearing plate inside the through opening, connecting plates fixedly connected to the bottom of both ends of the bearing plate, a traction plate fixedly connected to the bottom of the connecting plate, a limiting groove on the side wall of the upright plate, the traction plate being slidably inserted into the limiting groove, a motor fixedly connected to the installation plate, a threaded rod fixedly connected to the output end of the motor, a movable sleeve threaded onto the threaded rod, and a push plate fixedly connected to the top end of the movable sleeve.

[0006] Preferably, the top of the support plate is arranged parallel to the bottom of the mold cavity.

[0007] Preferably, the mounting plate has mounting holes at all four corners, and fixing bolts are inserted into the mounting holes.

[0008] Preferably, telescopic rods are fixedly connected to the bottom of both ends of the push plate and the mounting plate.

[0009] Preferably, the motor is a servo motor.

[0010] Preferably, a sliding rod is fixedly connected inside the limiting groove, and the traction plate is slidably sleeved on the sliding rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This tablet computer casing injection mold uses a mounting plate fixed to a worktable and a support plate set inside the mold cavity of the fixed mold. The support plate serves as the bottom of the fixed mold. After injection molding and cooling, the mold can be started by controlling a motor. When the motor starts, it will cause the threaded rod to rotate. At this time, the movable sleeve threaded onto the threaded rod pushes the push plate under the meshing action of the threaded opening. The push plate then pushes the support plate upward. At this time, the workpiece inside the mold cavity is pushed out of the mold cavity by the support plate, which facilitates unloading. This utility model can eject and demold through the linkage operation of the motor, making demolding more convenient and faster. Attached Figure Description

[0019] Please see Figure 1-2 This utility model provides an embodiment of a tablet computer shell injection mold, including a mounting plate 1, a fixed mold 2 above the mounting plate 1, a mold cavity 3 on the fixed mold 2, the fixed mold 2 being fixed above the mounting plate 1 by two symmetrically arranged upright plates 4, a through opening at the bottom of the mold cavity 3, a bearing plate 5 inside the through opening, connecting plates 6 being fixedly connected to the bottom of both ends of the bearing plate 5, a traction plate 7 being fixedly connected to the bottom of the connecting plate 6, a limiting groove being provided on the side wall of the upright plate 4, the traction plate 7 being slidably inserted into the limiting groove, a motor 8 being fixedly connected to the mounting plate 1, and a threaded rod 9 being fixedly connected to the output end of the motor 8. A movable sleeve 10 is threaded onto the 9th mold, and a push plate 11 is fixedly connected to the top of the movable sleeve 10. Specifically, the mounting plate 1 is fixed on the worktable, and a support plate 5 is set inside the mold cavity 3 of the fixed mold 2. The support plate 5 serves as the bottom of the fixed mold 2. After injection molding and cooling, the motor 8 can be started. When the motor 8 starts, it will cause the threaded rod 9 to rotate. At this time, the movable sleeve 10 threaded onto the threaded rod 9 pushes the push plate 11 under the meshing action of the threaded opening. The push plate 11 will then push the support plate 5 upward. At this time, the workpiece in the mold cavity 3 will be pushed out of the mold cavity 3 by the support plate 5, which will facilitate unloading.

[0020] In this embodiment, the top of the bearing plate 5 is parallel to the bottom of the mold cavity 3; the four corners of the mounting plate 1 are provided with assembly holes, and fixing bolts 12 are inserted into the assembly holes to facilitate the fixing of the mounting plate 1; the bottom ends of the push plate 11 are fixedly connected to the mounting plate 1 with telescopic rods 13 to increase the stability of the push plate 11; the motor 8 is a servo motor; a sliding rod 14 is fixedly connected in the limiting groove, and the traction plate 7 is slidably sleeved on the sliding rod 14 to provide sliding support for the traction plate 7.

[0021] Working principle: First, the mounting plate 1 is fixed on the worktable. The support plate 5 is set inside the mold cavity 3 of the fixed mold 2. The support plate 5 serves as the bottom of the fixed mold 2. After the injection molding is completed and cooled, the motor 8 can be started. When the motor 8 starts, it will cause the threaded rod 9 to rotate. At this time, the movable sleeve 10, which is threaded onto the threaded rod 9, pushes the push plate 11 under the meshing action of the thread. The push plate 11 will then push the support plate 5 upward. At this time, the workpiece in the mold cavity 3 is pushed out of the mold cavity 3 by the support plate 5, which facilitates the unloading of the material.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
