Description

Technical Field

[0001] The utility model relates to the field of mold locking mechanisms, in particular to a mold locking mechanism for a notebook shell mold. Background Art

[0002] A common clamping mechanism used in laptop casing molds is a transverse clamping method. This mechanism achieves locking through clamping pins and holes installed in the upper and lower parts of the mold. This is particularly important for manufacturing products that require high precision and repeatability, such as laptop casings.

[0003] After searching, the existing Chinese patent announcement number is: CN217622024U, a locking mechanism for a notebook shell mold, comprising a mounting seat and an upper mold, a lower mold is installed in the middle of the top of the mounting seat, and an electric push rod is installed in the middle of the bottom of the mounting seat, and the output end of the electric push rod is provided with a push plate, push rods are installed on both sides of the top of the push plate, and outer sleeves are installed on the tops of the two groups of push rods, and a movable rod is slidably inserted on the side where the two groups of outer sleeves are close to each other; the utility model cooperates with the electric push rod, push plate, spring, outer sleeve, locking module, arc edge and movable rod so that when the upper mold is controlled to move downward, the locking module can be automatically pushed to move to both sides. After the upper mold is closed, the locking module can automatically pop out to the top of the upper mold. The device only needs to control the locking module to move downward to press the top of the upper mold, so that the device can achieve the locking effect through a set of driving force.

[0004] In the above patent, when the upper mold moves down to close the mold, the device can contact the locking module through the arc edge, so that the upper mold can push the locking module to move toward the inner side of the outer sleeve under the guidance of the movable rod, and during the movement, it can push the spring to compress. After the upper mold and the lower mold are closed, the elastic restoring force of the spring can be used to push the locking module to reset so that the locking module is located at the top of the upper mold. At this time, the electric push rod is started to run, and the push plate can be pushed down by the electric push rod. Then the push plate can pull the outer sleeve down under the connection of the push rod, and the locking module is driven by the outer sleeve so that the locking module can be pressed on the top of the upper mold to lock the mold. However, in this patent, the upper mold will be blocked by the locking module when it rises. When the upper mold is to be reset, it is necessary to manually open the locking modules on both sides, which increases the operation steps and complexity. In particular, it may affect production efficiency in high-frequency production. There is also an operational risk of human error. For example, if the locking module is not opened when the upper mold is reset, it may cause the locking module to malfunction. For this reason, a locking mechanism for a notebook shell mold is proposed to solve the above problems. Utility Model Content

[0037] like Figure 2 and Figure 4 As shown, the discharging assembly includes a motor 15, a rotating disk 16 and a driving protrusion 17. The motor 15 is installed at the bottom end of the lower mold 6. The motor 15 is designed to facilitate the rotation of the rotating disk 16. The rear end of the rotating disk 16 is fixedly connected to the driving end of the motor 15. The rotating disk 16 is designed to cooperate with the driving protrusion 17.

After the upper mold 5 falls into the interior of the lower mold 6, the electric push rod 2 will continue to press the pushing bar 3 downward, allowing the pushing bar 3 to press the lower pressure rod 12. The lower pressure rod 12 will drive the driving plate 11 through the connecting protrusion 13, thereby driving the locking column 8, allowing the locking column 8 to engage with the locking groove 7, so that the locking column 8 and the locking groove 7 cooperate to lock the upper mold 5 and the lower mold 6. At this time, injection molding can be performed on the interior of the upper mold 5 and the lower mold 6 through the injection molding device. After the injection molding is completed, the electric push rod 2 is started, and the electric push rod 2 is allowed to lift the sliding seat 4 and the upper mold 5 through the pushing bar 3. When the pushing bar 3 is lifted, the lower pressure rod 12 will not be squeezed, and the pushing spring 10 will also push the pushing ring 9, thereby pushing the locking column 8, allowing the locking column 8 to separate from the inside of the locking groove 7, thereby automatically releasing the mold lock. By allowing the push bar 3 to no longer squeeze the lower pressure rod 12, the push spring 10 pushes the push ring 9, thereby pushing the locking column 8, so that the mold lock can be automatically released, avoiding manual operation, eliminating the risk of human operation, reducing the operation steps and complexity, and ensuring that production efficiency will not be affected. When the upper mold 5 and the lower mold 6 are separated, start the motor 15 and let the motor 15 drive the rotating disk 16 to rotate. When the rotating disk 16 rotates, it drives the driving ring 18 and the lifting column 19 to rise and fall by driving the protrusion 17, thereby driving the push plate 14 to push the notebook shell injected in the lower mold 6 out of the interior of the lower mold 6, thereby eliminating the step of separating the shell from the lower mold 6, and the shell can be taken directly, thereby reducing the labor intensity of the workers.
