DETAILED DESCRIPTION

[0029] The present application provides the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present disclosure as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those of ordinary skill 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 present disclosure. In addition, descriptions of well-known functions and configurations can be omitted for clarity and conciseness.

[0030] The terms and words used in the following description and claims are not limited to the literal meanings but are used by the inventors to enable a clear and consistent understanding of the present disclosure. Accordingly, those skilled in the art will appreciate that the description provided below of various embodiments of the present disclosure is merely exemplary and is not intended to limit the present disclosure as defined by the appended claims and their equivalents.

[0031] It is to be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component surface" includes reference to one or more of such surfaces.

[0032] The terms "have," "may have," "include," or "may include" used in various embodiments of the present disclosure indicate the presence of the corresponding function, operation, element, etc. disclosed, but do not limit one or more additional functions, operations, elements, etc.

[0033] Furthermore, it should be understood that the terms “comprising” or “having” used in the various embodiments of this disclosure are intended to indicate the presence of features, numbers, operations, elements, components or combinations thereof described in the specification, but do not exclude the presence or addition of one or more other features, numbers, operations, elements, components or combinations thereof.

[0034] like Figures 1-10 As shown, the present invention provides a car cup holder mold, including a front mold assembly 100, a front mold core 200, a rear mold core 300, and a rear mold assembly 400; the rear mold core 300 is provided with a forming part 310 for forming the car cup holder, and the rear mold assembly 400 includes a rear template 410 and a plurality of slider assemblies 420. The slider assembly 420 is used to form the deformable part of the car cup holder and can discharge gas at the deformable part during the injection molding process. The slider assembly 420 includes a slider base 421, a forming block 422, and a venting block 423. One or two forming blocks 422 are connected to the slider base 421. Each forming block 422 is provided with an accommodating space. The venting block 423 is embedded in the accommodating space and the forming end of the venting block 423 is aligned with the deformable part of the car cup holder. This invention solves the problem of "trapped air" during the molding of car cup holders by setting a slider assembly 420 with a venting function in the deformable part of the cup holder. During the injection molding process, on the one hand, the vent block 423 itself can vent the gas in the deformable part. On the other hand, since there will be some gaps after the slider base 421, the molding block 422 and the vent block 423 are assembled, they can also play a good venting role, thereby solving the problem of "trapped air" during the molding of car cup holders and ensuring the molding quality of car cup holders.

[0035] Depending on actual needs, the slider assembly 420 can take various forms. It can be a slider base 421 connected to one molding block 422, or it can be a slider base 421 connected to two molding blocks 422. Specifically, the slider base 421 of the slider assembly 420 located on the left and right sides of the rear template 410 is connected to two molding blocks 422, while the slider base 421 of the slider assembly 420 located on the upper and lower sides of the rear template 410 is connected to one molding block 422. The slider base 421 is provided with guide holes. The front mold assembly 100 includes a slanted guide rod. When the front mold assembly 100 and the rear mold assembly 400 are separated, the slanted guide rod will cause the slider assembly 420 to detach from the product. Connecting the slider base 421 of the slider assembly 420 located on the front and rear sides of the rear template 410 to two molding blocks 422 can reduce the number of slider bases 421 and slanted guide rods, making the mold structure simpler.

[0036] In some embodiments, the vent block 423 is made of ventilated steel. Ventilated steel has good air permeability, which facilitates the discharge of gas from the deformed part.

[0037] In some embodiments, in order to firmly connect the slider base 421 and the shaped block 422, the slider base 421 is provided with a connecting groove 4211, and the shaped block 422 is provided with a connecting protrusion 4221 matched with the connecting groove 4211.

[0038] In some embodiments, the slider base 421, the shaped block 422 and the air permeable block 423 are all provided with a pin hole, and the slider base 421, the shaped block 422 and the air permeable block 423 are fixedly connected through a pin. After the slider base 421, the shaped block 422 and the air permeable block 423 are fixedly connected, there is a small gap between them, which is beneficial to assist in exhausting air and ensure the forming quality of the automobile cup holder.

[0039] In some embodiments, in order to facilitate the automobile cup holder to be separated from the back mold core 300 after being formed, the base 421 is provided with an air inlet 4212, and the shaped block 422 is provided with an air outlet 4222 which is communicated to the forming cavity. After the automobile cup holder is formed and cooled, air is blown into the forming cavity through the air inlet 4212, which reduces the adhesion between the automobile cup holder and the back mold core 300, thereby facilitating the automobile cup holder to be taken out from the back mold core 300 by hand or a mechanical hand.

[0040] More specifically, the back mold core 300 is provided with a groove 320 corresponding to the position of the air outlet 4222, and a ventilation passage 330 is arranged between the groove 320 and the forming cavity. The air blown from the air inlet 4212 passes through the groove 320 and then passes through the ventilation passage 330 to the forming cavity of the automobile cup holder, which reduces the adhesion between the automobile cup holder and the back mold core 300, thereby facilitating the automobile cup holder to be taken out from the back mold core 300 by hand or a mechanical hand.

[0041] In some embodiments, in order to further facilitate the air in the groove 320 to blow into the ventilation passage 330, the side of the groove 320 close to the ventilation passage 330 is provided with a wind guide surface 340. This makes it easier for air to enter the ventilation passage 330 from the groove 320.

[0042] In some embodiments, the height of the ventilation passage 330 is 0.01mm-0.03mm. The ventilation passage 330 with this height can ensure that air can enter the forming cavity without causing obvious burrs on the surface of the automobile cup holder.

[0043] In some embodiments, the front mold core 200 is provided with an air avoiding groove 210 for accommodating the slider assembly 420. After the mold is closed, the slider assembly 420 is located in the air avoiding groove 210, so that the mold structure is compact and the overall occupied space is smaller.

[0044] The above further describes the present application in detail in combination with specific embodiments, and cannot be deemed as limitation of the specific embodiments of the present application. Those skilled in the art to which the present application belongs can make some simple deductions or replacements without departing from the concept of the present application.
