[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-8, a technical solution provided by the utility model:

[0027] In this embodiment, a charger housing injection molding device that facilitates rapid demolding includes a lower module 1 and an upper module 2. The lower module 1 is located at the bottom of the upper module 2, and each module is provided with multiple corresponding injection holes. The multiple corresponding injection holes ensure uniform thickness at all parts of the charger housing during the injection molding process, improving product quality. The coordination between the lower module 1 and the upper module 2 and the corresponding injection hole design provide guarantees for improved product quality.

[0028] An injection port is provided on one side of the lower mold assembly 1. A groove is provided on the bottom of the injection port. A stripper plate 3 is provided in the groove. A lifting assembly 4 is provided at the bottom of the stripper plate 3. The groove design provides installation space for the stripper plate 3, making the demolding operation more stable and helping to improve demolding efficiency. The stripper plate 3 and the lifting assembly 4 cooperate with the groove to better complete the demolding operation.

[0029] The lower mold assembly 1 has two rectangular cavities, each with a drive motor mounted on its inner wall. The drive motor's power output shaft is connected to a striking assembly 5. The rectangular cavities provide mounting locations for the drive motor and striking assembly 5, making the device more compact and reducing its footprint. The combination of the drive motor and striking assembly 5 provides a vibrating force for demolding.

[0030] Embedded within the inner wall of the rectangular cavity is a conductive component 6 that mates with the striking component 5. This combination effectively transmits vibration force to the inner wall of the injection port, facilitating rapid demolding of the charger housing. The synergistic effect of the conductive component 6 and the striking component 5 supports efficient demolding.

[0031] The striking assembly 5 includes a rotating rod 51, one end of which is connected to the power output shaft of the drive motor. A rotating sleeve 52 is connected to the outer wall of the rotating rod 51. A plurality of springs arranged in a circular array are connected to the outer wall of the rotating sleeve 52. Each of the springs has a metal ball 53 connected to its other end. The circular array of springs and metal balls 53 generates a uniform vibration force during rotation, improving the demolding effect and stability. The combination of the rotating rod 51, rotating sleeve 52, springs, and metal balls 53 ensures stable vibration force output.

[0032] The conduction assembly 6 comprises a mounting plate 61 and a conduction plate 62. The mounting plate 61 is mounted on the inner side wall of the rectangular cavity near the injection port side by bolts. The conduction plate 62 is connected to the side wall of the mounting plate 61 and is arranged in an array. The conduction plate 62 is provided with a plurality of conduction plates 62, and one side of the plurality of conduction plates 62 is connected with two knocking blocks 63 matched with the metal ball 53. The mounting plate 61 facilitates the installation and disassembly of the conduction plate 62, and facilitates the maintenance and repair of the equipment. The design of the mounting plate 61 and the conduction plate 62 provides convenience for the maintenance of the equipment. The plurality of conduction plates 62 and the knocking blocks 63 can better transmit the vibration force and improve the demolding efficiency. The cooperation of the conduction plate 62 and the knocking block 63 makes the transmission of the vibration force more efficient.

[0033] The top of the upper mold group 2 is connected with a hydraulic drive device. The hydraulic drive device can provide strong driving force, ensure the close combination between the upper mold group 2 and the lower mold group 1, improve the injection quality, and provide power support for the close combination of the upper mold group 2 and the lower mold group 1.

[0034] The lifting assembly 4 comprises a demolding push plate 40, an electric telescopic rod 41, a limiting rod 42 and a drive controller 43. The demolding push plate 40 is located in the inner cavity of the groove, the bottom of the demolding push plate 40 is connected with the electric telescopic rod 41, the limiting rod 42 is provided with a plurality of limiting rods 42, one end of the plurality of limiting rods 42 is slidably connected in the lower mold group 1, the drive controller 43 is connected to the bottom of the lower mold group 1, the drive controller 43 is electrically connected with the electric telescopic rod 41, the two sides of the drive controller 43 are connected with a base 7, and the base 7 is connected to the bottom of the lower mold group 1. The cooperation of the demolding push plate 40 and the electric telescopic rod 41 can realize precise demolding operation, and the demolding push plate 40 and the electric telescopic rod 41 provide power for precise demolding. The limiting rod 42 can ensure the stable movement direction of the demolding push plate 40 and improve the accuracy of demolding, and the limiting rod 42 provides protection for the stable movement of the demolding push plate 40. The drive controller 43 facilitates the control of the electric telescopic rod 41, improves the automation degree of the equipment, and improves the automation control level of the equipment. The base 7 provides stable support for the equipment, and the base 7 ensures the stability of the equipment.

[0035] The bottom of the upper mold group 2 is provided with an extrusion block 21 matched with the injection port, and the bottom of the upper mold group 2 is also provided with a sealing ring 22. The extrusion block 21 can ensure the uniformity of the pressure during the injection molding process, improve the quality of the charger shell, and provide support for the uniform distribution of the injection pressure. The sealing ring 22 can prevent leakage of raw materials during the injection molding process, improve production efficiency, and ensure the sealing property of the injection molding process.

[0036] The top of the lower mold group 1 is provided with a sealing clamping groove matched with the sealing ring 22. The cooperation of the sealing clamping groove and the sealing ring 22 further improves the sealing property of the equipment, ensures the stable operation of the injection molding process, and improves the sealing performance of the equipment.

[0037] Working principle: When in use, the material is first injected through the injection port, and the hydraulic drive device connected to the top of the upper mold assembly 2 drives the upper mold assembly 2 to move to the bottom, and the extrusion block 21 presses down to perform injection extrusion. After completion, the charger shell cools down and the lifting component 4 is started. The driving force is gradually increased through the electric telescopic rod 41, pushing the demoulding push plate 40 to move to the bottom;

[0038] At the same time, the driving motor is started synchronously, and the rotating rod 51 is driven to rotate by the power output shaft of the driving motor, and the rotating sleeve 52 and the metal ball 53 connected to the rotating sleeve 52 by a spring are driven to rotate by the rotating rod 51, and the metal ball 53 hits the knocking block 63 when rotating; the synchronous driving of the lifting component 4 and the knocking component 5 can make it possible to demold with maximum efficiency through vibration and promotion when the charger shell cools and sticks to the side wall during the demolding process, and can ensure the integrity of the outer side of the charger shell after demolding, thereby ensuring product quality.

[0039] The striking block 63 transmits the vibration force of the impact to the conductive plate 62 connected to the striking block 63. Through the connection relationship between multiple conductive plates 62 inserted into the inner wall of the rectangular cavity, the vibration force on the conductive plate 62 is transmitted to the inner wall of the injection port.

[0040] In conjunction with the push of the lifting component 4, the process is carried out synchronously. When the charger shell is shaken off from the side wall by vibration, the lifting component 4 pushes the charger shell out to complete the demoulding operation. Compared with the traditional equipment's direct demoulding method, the charger shell is separated from the inner wall of the injection port by vibration. Therefore, when the demoulding is carried out in conjunction with the pushing force of the lifting component 4, the adhesion between the charger shell and the inner wall of the injection port is eliminated, avoiding the situation where the charger shell is damaged by uneven force during demoulding.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
