[0002] As a portable refrigeration device, the stability and durability of the shell structure of a car refrigerator are crucial to maintaining the performance of the refrigerator. The shell of a traditional car refrigerator is usually made of plastic material through injection molding, but there are some technical challenges in the manufacturing process.

[0003] In the existing car refrigerator shell design, Figure 1 As shown, the vehicle refrigerator housing 10 needs to be installed with the vehicle refrigerator housing rotating shaft sleeve 11 during production. In the prior art, the vehicle refrigerator housing 10 is often integrated through secondary processing after being formed. This method not only increases production costs, but may also cause the connection between the vehicle refrigerator housing 10 and the vehicle refrigerator housing rotating shaft sleeve 11 to be not firm enough, affecting the overall performance.

[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 a rapid prototyping mold for a vehicle refrigerator shell, comprising:

[0038] The upper mold assembly 1 is provided with an upper mold core 2;

[0039] The lower mold assembly 3 is provided with a lower mold core 4;

[0040] A pre-installation mechanism 5, arranged on the lower mold assembly 3, for pre-installing a rotating shaft sleeve of the vehicle refrigerator housing;

[0041] Among them, a fixed block 301 is provided on the lower mold assembly 3, the pre-loading mechanism 5 includes a guide block 501 and a slanted top 502 driving the guide block 501, the guide block 501 includes a pre-loading part 503, the pre-loading part 503 includes a fixed shaft 504, the bottom of the guide block 501 is connected to the lower mold assembly 3, and a limit block 505 is provided on the guide block 501, the top of the limit block 505 is connected to the bottom of the fixed block 301, when the slanted top 502 moves up and down, the pre-loading part 503 moves left and right under the limit of the limit block 505 and the lower mold assembly 3.

[0042] By arranging the pre-installed part 503 in the mold, the fixed shaft 504 of the pre-installed part 503 can pre-install the rotating shaft sleeve of the vehicle refrigerator shell in the mold before injection molding, thereby realizing the injection molding of the vehicle refrigerator shell and the rotating shaft sleeve.

[0043] Due to the shape limitation of the vehicle refrigerator shell, the pre-installation mechanism 5 is inside the vehicle refrigerator shell, and the conventional demoulding mechanism cannot demould the pre-installation mechanism 5. In this embodiment, a fixed block 301 is set on the lower mold assembly 3, and the lower mold assembly 3 and the fixed block 301 enclose a space for limiting the movement of the pre-installation mechanism 5. The pre-installation mechanism 5 is limited by the cooperation of the fixed block 301 and the lower mold assembly 3, so that the pre-installed parts can be driven by the inclined top 502 to move in the enclosed space and complete the demoulding under the limitation of the lower mold assembly 3 and the fixed block 301.

[0044] In some embodiments, a positioning mechanism 506 is provided on the fixing block 301 , and a positioning portion 507 matching the positioning mechanism 506 is provided on the guiding block 501 .

[0045] The positioning mechanism 506 can further limit the position of the pre-installation mechanism 5 , and the movement position of the pre-installation mechanism 5 can be effectively controlled through the cooperation and limitation between the positioning mechanism 506 and the positioning portion 507 .

[0046] Furthermore, the positioning mechanism 506 includes a positioning pin 508 disposed on the fixing block 301 , and the positioning portion 507 includes a first positioning hole 509 and a second positioning hole 510 disposed on a horizontal movement path of the positioning pin 508 .

[0047] In this embodiment, the pre-installation mechanism 5 is positioned by a fixing pin, a first positioning hole 509 and a second positioning hole 510. The positioning pin 508 of the positioning mechanism 506 is first fixed on the first positioning hole 509 of the pre-installation mechanism 5. When the inclined top 502 moves upward, the pre-installation mechanism 5 moves horizontally. At this time, the first positioning hole 509 is disengaged from the positioning pin 508. When the second positioning hole 510 moves to the position of the positioning pin 508, it is matched and connected with the positioning pin 508 to complete the positioning of the pre-installation mechanism 5, thereby improving the accuracy of the moving position of the pre-installation mechanism 5.

[0048] In some embodiments, a truncated table 511 for clamping a rotating shaft sleeve of the vehicle refrigerator housing is provided at the connection between the fixed shaft 504 and the pre-installed portion 503 .

[0049] The diameter of the table 511 gradually increases. During the process of inserting the rotating shaft sleeve of the vehicle refrigerator shell into the fixed shaft 504, when the diameter of the table 511 is larger than the inner diameter of the rotating shaft sleeve of the vehicle refrigerator shell, the rotating shaft sleeve of the vehicle refrigerator shell will be fixed on the table 511.

[0050] In some embodiments, a cavity 512 is provided at the lower portion of the guide block 501 , and the pre-installed portion 503 is provided at the bottom of the cavity 512 .

[0051] The provision of the cavity 512 can save space in the mold, allowing other components to be installed in the mold, and can also save the manufacturing cost of the mold.

[0052] Furthermore, the surface where the guide block 501 and the inclined top 502 are matched and connected is an inclined surface, and the guide block 501 is inclined outward from top to bottom.

[0053] Furthermore, the pre-installed portion 503 includes a bearing seat body 513 , and the fixed shaft 504 is fixed at an axial hole 514 of the bearing seat body 513 .

[0054] The bottom of the bearing seat body 513 is in contact with the lower mold assembly 3 to improve the stability of the movement of the pre-installation mechanism 5.

[0055] In some embodiments, a slide groove 515 is provided on the guide block 501 , and a protrusion 516 that can slide on the slide groove 515 is provided on the inclined top 502 , and the shape of the protrusion 516 matches the shape of the slide groove 515 .

[0056] 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.
