[0026] Please see Figures 1 to 4The present invention provides an embodiment of an injection mold for a car model faceplate, the injection mold comprising a lower mold 3, an upper mold 4, a conveyor 7, and an mounting component 8; the lower mold 3 is located at the bottom of the upper mold 4, the conveyor 7 is located on one side of the top of the upper mold 4, and the mounting component 8 is disposed on the top of the conveyor 7;

[0027] The lower mold 3 and the upper mold 4 constitute the cavity and core of the mold, which together form the molding space for the car body after the mold is closed.

[0028] Mounting component 8 includes guide post 81, support post 82, connecting post 83, movable plate 84, and second spring 85; guide post 81 and support post 82 are fixed on one side of the upper mold 4, and the guide post 81 is symmetrically distributed at both ends of the conveying component 7. The support post 82 is located at the top of the guide post 81. The connecting post 83 is fixed at both ends of the lower surface of the support post 82, and the connecting post 83 passes through and connects to the inside of the guide post 81. The movable plate 84 is fixed on the upper surface of the connecting post 83. The second spring 85 is fixed inside the support post 82, and the top of the second spring 85 is fixed to the bottom of the movable plate 84.

[0029] The guide post 81 is used to connect with the fixing frame 74 so that the delivery tube 71 is stably inserted into the desired position. The support post 82 houses the second spring 85. The connecting post 83 is used to insert into the guide post 81 so that the delivery tube 71 is fixed in the desired position. The movable plate 84 is used to change the position of the connecting post 83. The second spring 85 provides elasticity so that the connecting post 83 automatically resets and inserts into the guide post 81.

[0030] The movable plate 84 is rotatably connected to a rotating column 86, and the support column 82 has a connecting hole 87 inside, and the connecting hole 87 is square.

[0031] By flipping the rotating column 86 so that it is inserted into the connecting hole 87, the movable plate 84 can be restricted to a certain height.

[0032] The bottom of the lower mold 3 is provided with a base 1, and a first spring 2 is fixed inside the base 1. The top of the first spring 2 is fixed to the bottom of the lower mold 3.

[0033] The base 1 is used to support the lower mold 3 and provide a basic installation platform. The first spring 2 buffers the impact force when the upper mold 4 is pressed down, reducing mold vibration and wear.

[0034] A second guide block 6 is fixed inside the top of the lower mold 3. The cross-section of the second guide block 6 is convex.

[0035] The bottom end of the upper mold 4 is fixed with a first guide block 5. The cross-section of the first guide block 5 is concave, and the first guide block 5 and the second guide block 6 are connected by insertion.

[0036] The first guide block 5 is used to insert and cooperate with the second guide block 6 to ensure mold closing accuracy and prevent misalignment;

[0037] The conveying component 7 includes a conveying pipe 71, a connecting pipe 72, and a semi-arc groove 73. The conveying pipe 71 is inserted into the interior of one side of the upper mold 4, the connecting pipe 72 is threaded into the interior of the conveying pipe 71 near the upper mold 4, and the semi-arc groove 73 is opened on one side of the top of the connecting pipe 72.

[0038] The delivery pipe 71 is used to deliver resin between the upper mold 4 and the lower mold 3. With the design of the semi-arc groove 73, residual resin can be left inside the connecting pipe 72 to prevent resin from dripping and contaminating the product.

[0039] A fixing frame 74 is fixed on the outer surface of the conveying pipe 71. The fixing frame 74 is sleeved on the outside of the guide post 81. A sealing ring 75 is fixed on the surface of the fixing frame 74 and the sealing ring 75 is inserted into the inside of the upper mold 4.

[0040] The retainer 74 is used to position and limit the delivery pipe 71 in the desired position, and the sealing ring 75 prevents resin leakage;

[0041] Working principle: When it is necessary to produce the car model shell, the drive component connected to the top of the upper mold 4 first moves the upper mold 4 downward. Under the design of the first spring 2, the impact force between the lower mold 3 and the base 1 is reduced. With the connection of the first guide block 5 and the second guide block 6, after the upper mold 4 and the lower mold 3 are closed, the resin flows into the mold through the delivery pipe 71. With the design of the connecting pipe 72 and the semi-arc groove 73, the resin remaining in the delivery pipe 71 is prevented from continuing to drip during molding, which would affect the appearance of the product. In this embodiment, the drive component is the prior art, and will not be described in detail here.

[0042] When it is necessary to clean the conveying pipe 71 and the connecting pipe 72, an upward force is applied to the movable plate 84, causing the connecting column 83 to disengage from the guide column 81. Then, a flipping force is applied to the rotating column 86, adjusting it from a horizontal to a vertical position. The force applied to the movable plate 84 is then released, allowing the rotating column 86 to insert into the connecting hole 87. Finally, a pulling force is applied to the conveying pipe 71, removing it from the upper mold 4. Then, a rotational force is applied to the connecting pipe 72, causing the conveying pipe 71 to... After cleaning the connecting pipe 72, the conveying pipe 71 is then connected to the connecting pipe 72. The conveying pipe 71 is inserted into the upper mold 4, so that the sealing ring 75 is inserted into the upper mold 4. At the same time, after the fixing bracket 74 is fitted onto the outside of the guide post 81, an upward pulling force is applied to the movable plate 84, and the rotating post 86 is retracted into the movable plate 84. Then the force applied to the movable plate 84 is released, and under the elastic force of the second spring 85, the connecting post 83 is inserted into the guide post 81.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
