[0034] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0035] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0037] The embodiment of the utility model provides an integrated molding die for installing a damping silent lock, comprising:

[0038] Panel assembly 1;

[0039] Upper mold assembly 2;

[0040] Upper mold core 3;

[0041] Lower mold assembly 4;

[0042] The lower mold core 5 includes a first molding mechanism 6 for molding the bearing seat 12, a second molding mechanism 7 for molding the shaft cavity 13, a third molding mechanism 8 for molding the damping and silent locking portion 14, and a pre-installation mechanism 9 for pre-installing the nut 11;

[0043] The third molding mechanism 8 includes a first core 81 inserted into the lower mold core 5 , and the pre-installation mechanism 9 includes a limiting column 91 whose diameter matches the inner diameter of the nut 11 .

[0044] Before closing the mold, the nut 11 needs to be pre-installed on the limiting column 91 of the pre-installation mechanism 9. After the pre-installation is completed, the injection molding machine injects the molten plastic material into the mold, and the plastic material flows inside the mold and fills the shape. After cooling and solidification, the mold is opened, and the molded and pre-installed injection molded part with the nut 11 is taken out, completing the entire injection molding process. The mold of the utility model can not only ensure the precise molding of the injection molded part and the nut 11, but also improve production efficiency, reduce costs, and simplify the production process.

[0045] The first molding mechanism 6 is used to mold the bearing seat 12, which is the part of the housing that is used for rotation.

[0046] The second molding mechanism 7 is used to mold the shaft cavity 13, so as to facilitate the installation of the shaft after the shell is molded.

[0047] The third molding mechanism 8 is used to mold the damping and silent locking positioning portion 14, which is used to position the installation of the damping and silent lock.

[0048] The first core 81 of the third molding mechanism 8 is plugged into the lower mold core 5. During the injection molding or other molding process, the air in the mold and the gas released by the material need to be effectively discharged to avoid bubbles or cavities inside the product. The design of the first core 81 facilitates the discharge of gas from the mold, thereby ensuring the integrity and performance of the product and preventing the formation of a joint line on the product surface.

[0049] In some embodiments, the pre-installation mechanism 9 further includes a receiving cavity 92 matching the outer diameter of the nut 11 , and the limiting column 91 is inserted into the receiving cavity 92 .

[0050] The diameter of the accommodating cavity 92 matches the outer diameter of the nut 11 and is used to accommodate the nut 11 . The position of the nut 11 is further limited by the accommodating cavity 92 .

[0051] In some embodiments, the lower mold core 5 is provided with a cavity 51 for molding a damping and silent locking portion 14, the third molding mechanism 8 includes a first molding portion 82 arranged in the cavity 51, and the first core 81 is inserted in the cavity 51 and jointly molds the damping and silent locking portion 14 with the first molding portion 82.

[0052] The first molding part 82 is arranged in the cavity 51, and is used to cooperate with the first core 81 to jointly form the damping and silent locking part 14. Here, the molding of the damping and silent locking part is divided into two parts: the first molding part 82 and the first core 81, which helps to exhaust more effectively and ensure that the air inside the mold and the gas released by the material can be discharged smoothly.

[0053] Furthermore, the first molding part 82 includes a first fixed seat 83, a second core 84 is provided on the first fixed seat 83, the first core 81 is provided with a second fixed seat 85, and a third core 86 is also provided in the cavity 51. One end of the third core 86 passes through the cavity 51, and the other end is connected to the first fixed seat 83 and the second fixed seat 85. The first core 81, the second core 84 and the third core 86 jointly form the damping and silent locking part 14.

[0054] The molding process of the damping and silent locking position part is further refined here. The precise molding of complex shapes is achieved through the coordinated work of the first molding part 82, the first core 81, the second core 84 and the third core 86. Separately designing the core and the molding part can more accurately control the molding process and improve the molding accuracy.

[0055] Furthermore, the third core 86 is in a 7-shape, and the upper end of the third core 86 is in a U-shape. One side of the upper end of the third core 86 is connected to the first fixing seat 83 , and the other side is connected to the second fixing seat 85 .

[0056] The 7-shaped third core 86 can be fixed on the first fixing seat 83 and the second fixing seat 85 to form a stable structure, thereby ensuring that the position of the core is accurate and stable during the injection molding process.

[0057] In some embodiments, the first molding mechanism 6 includes a first base 61 slidably connected to the lower mold assembly 4, and the first base 61 is provided with a first guide column hole 62 that cooperates with the inclined guide column of the upper mold assembly 2, and the front end of the first base 61 is provided with a bearing seat molding part 63 for molding the bearing seat 12.

[0058] The first molding mechanism 6 can slide under the drive of the inclined guide pillar to achieve mold closing and demoulding.

[0059] Furthermore, the second molding mechanism 7 includes a second base 71 slidably connected to the lower mold assembly 4, the second base 71 is provided with a second guide column hole 72 that cooperates with the inclined guide column of the panel assembly 1, and the front end of the second base 71 is provided with a shaft cavity molding part 73 for molding the shaft cavity 13, and the shaft cavity molding part 73 is provided with a fixed shaft 74.

[0060] The second molding mechanism 7 can slide under the drive of the inclined guide pillar to achieve mold closing and demoulding. The fixed shaft 74 is used to form a rotating shaft cavity.

[0061] Furthermore, the bearing seat forming part 63 is provided with a positioning groove 75, and the shaft cavity forming part 73 is matched with the positioning groove 75. When the shaft cavity forming part 73 is matched with the bearing seat forming part 63, the fixed shaft 74 is located at the shaft hole of the bearing seat formed by the first molding mechanism 6.

[0062] The bearing seat forming part 63 is provided with a positioning groove 75, which is used to ensure that the shaft cavity forming part 73 can be accurately aligned with the bearing seat forming part 63. When the shaft cavity forming part 73 is matched with the bearing seat forming part 63, the fixed shaft 74 is positioned at the shaft hole of the bearing seat formed by the first forming mechanism 6, ensuring the correct installation of the shaft and the function of the bearing seat.

[0063] After the injection molding is completed and cooled, the panel assembly 1 first drives the inclined guide column to move upward. At this time, the first molding mechanism 6 and the second molding mechanism 7 are laterally separated from the plastic part under the action of the inclined guide column, and then the upper mold assembly 2 drives the first molding mechanism 6 and the second molding mechanism 7 to move upward, so that the first molding mechanism 6 and the second molding mechanism 7 are longitudinally separated from the plastic part, realizing one-time demolding.

[0064] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
