[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 injection molding mold for a vehicle refrigerator body, comprising:
[0038] The upper mold assembly 2 is provided with an upper mold core 201;
[0039] The lower mold assembly 3 is provided with a lower mold core 301;
[0040] The molding mechanism 4 is arranged on the lower mold assembly 3, and the molding mechanism 4 includes a base 401, a pre-installation seat 402 is arranged on the base 401, a first molding portion 403 is arranged on one side of the pre-installation seat 402, and a through hole 404 penetrating the first molding portion 403 is arranged on the pre-installation seat 402;
[0041] The pre-installation mechanism 5 comprises a housing 501 installed in the through hole 404 , and a mounting column 502 for pre-installing a hollow metal column is arranged in the housing 501 .
[0042] The hollow metal column needs to be pre-installed during the injection molding of the vehicle refrigerator box. Before the mold is closed, the hollow metal column needs to be installed in the installation column 502 of the pre-installation mechanism 5. 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 of the box. After cooling and curing, the mold is opened, and the box that has been molded and pre-installed with the hollow metal column is taken out, completing the entire injection molding process. The mold of the utility model can not only ensure the precise molding of the box and the hollow metal column, but also improve production efficiency, reduce costs, and simplify the production process.
[0043] The molding mechanism 4 is arranged on the lower mold assembly 3. The molding mechanism 4 comprises a base 401, on which a pre-installation seat 402 is arranged, which is a part for fixing and positioning the pre-installation mechanism 5.
[0044] The pre-installation seat 402 is located on the base 401, and a first molding portion 403 is provided on one side thereof. The first molding portion 403 is an area for molding a specific part of the box body. A through hole 404 is also provided on the pre-installation seat 402, and the through hole 404 passes through the first molding portion 403, and is used to install the pre-installation mechanism 5.
[0045] The through hole 404 is a through hole on the pre-installation seat 402, which allows the housing 501 of the pre-installation mechanism 5 to pass through, thereby providing space for the pre-installation of the hollow metal column.
[0046] The pre-installation mechanism 5 includes a housing 501 installed in the through hole 404. A mounting post 502 is provided inside the housing 501, which is a part for pre-installing the hollow metal column. The mounting post 502 must be designed to firmly fix the hollow metal column to ensure that the position of the metal column is accurate during the injection molding process.
[0047] In some embodiments, a fixing groove 405 is provided at one end of the through hole 404 away from the first forming portion 403 , and the housing 501 is provided with a fixing head 406 matching the shape of the fixing groove 405 .
[0048] Through the matching connection between the fixing head 406 and the fixing groove 405, the fixing groove 405 provides a stable support point for the shell 501, and the fixing head 406 fastens the shell 501. This connection method enhances the structural stability of the pre-installation mechanism 5, reduces any potential movement or deformation caused by mold movement during the injection molding process, and ensures the accurate positioning of the hollow metal column before injection molding, thereby ensuring the correct matching between the box body and the metal column and the stability of the overall structure.
[0049] Furthermore, the mounting column 502 is provided with a round table 503 for fastening the hollow metal column.
[0050] The diameter of the truncated cone 503 gradually increases, so that the mounting column 502 can more effectively fasten the hollow metal column, thereby improving the stability of the entire molding structure and helping to improve the durability and reliability of the final product.
[0051] As the diameter of the truncated cone 503 increases, the hollow metal column can more naturally find the center position when being pushed into the mounting column 502, reducing the difficulty of alignment and positioning, thereby improving the accuracy of assembly.
[0052] Furthermore, a second molded portion 407 is provided at one end of the housing 501 away from the fixing head 406 , and the second molded portion 407 includes protrusions arranged at intervals.
[0053] The second molding portion 407 enables the pre-installation mechanism 5 to be used not only for pre-installing hollow metal columns, but also for molding plastic parts.
[0054] In some embodiments, a fixing plate 408 for fixing the preinstallation mechanism 5 is provided on the preinstallation seat 402 .
[0055] The fixing plate 408 provides a stable fixing point for the pre-installation mechanism 5, ensuring that the pre-installation mechanism 5 remains fixed during the injection molding process and does not move axially, thereby avoiding displacement or vibration caused by mold movement.
[0056] In some embodiments, the pre-installation seat 402 is provided with a fixing hole 409 for fixing the fixture 6 of the clamping molding mechanism 4 .
[0057] Through the fixing hole 409 , the jig 6 can be quickly and conveniently installed on the pre-installation seat 402 , which simplifies the clamping process of the jig 6 and improves the preparation efficiency of the mold.
[0058] In some embodiments, a slide groove 410 is provided on the lower mold assembly 3 , and the base 401 is slidably connected in the slide groove 410 .
[0059] The slide groove 410 provides precise guidance for the base 401, ensuring that the base 401 moves along a predetermined trajectory when the mold is opened and closed, thereby ensuring the accuracy of the molding process.
[0060] Furthermore, an inclined guide column 202 is provided on the upper mold assembly 2 , and an inclined guide hole 411 matching with the inclined guide column 202 is provided on the base 401 .
[0061] The matching design of the oblique guide pillar 202 and the oblique guide hole 411 helps the mold to achieve more stable and smooth movement during the opening and closing process, reducing jamming and friction.
[0062] In some embodiments, a cooling pipe 412 is disposed in the molding mechanism 4 , and the cooling pipe 412 includes a water inlet 413 and a water outlet 414 .
[0063] The provision of the cooling pipe 412 enables the coolant to circulate inside the mold, thereby achieving a faster and more uniform cooling effect and accelerating the solidification process of the product.
[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.
