Description

Technical Field

[0001] This utility model relates to an injection mold for a rotating slider in an automobile. Background Technology

[0002] A car rotating slider is a plastic accessory installed on the cover of a car's storage compartment. Rotating the slider allows the storage compartment cover to rotate. Since car rotating sliders are made of plastic, their production relies on matching injection molds and corresponding injection molding machines.

[0003] Because the rotating slider of an automobile is designed with a hollow pin for rotation and connection, existing injection molds for rotating sliders mostly use linear motion devices such as cylinders to complete mold closing and core pulling in order to form the hollow pin. Although this simplifies the mold structure to some extent, it increases the mold manufacturing cost. In addition, existing injection molds for rotating sliders can only form two rotating sliders at a time, so the production efficiency is also low. Therefore, further improvements are needed. Utility Model Content

[0032] A rectangular cavity 133 is opened at the center of the bottom surface of each of the two rectangular recesses 135. The two inner forming blocks 34 in the upper alignment mechanism are movably and symmetrically arranged in the upper rectangular cavity 133, and the two inner forming blocks 34 in the lower alignment mechanism are movably and symmetrically arranged in the lower rectangular cavity 133.

[0040] Working principle:

[0041] The feed block 12 and the moving module 11 in the moving mold assembly 1 are both installed on the action mechanism of the injection molding machine. Then, the seat block 22 in the fixed mold assembly 2 is installed on the machine body of the injection molding machine. The action mechanism is operated to first drive the moving module 11 to move backward until the rear outer wall of the moving module 11 and the front outer wall of the fixed module 21 are joined together. At this time, the moving mold core 13 is also joined together with the fixed mold core 24 (existing technology).

[0042] The four trapezoidal moving mold cavities 131 on the moving mold core 13 are respectively matched with the openings of the four trapezoidal moving mold cavities 131 on the fixed mold core 24. Each core post 36 passes through a corresponding first countersunk hole 132 and is concentrically inserted into the end opening of a corresponding core sleeve 37.

[0043] Then, the actuation mechanism is manipulated to move the feed block 12 backward to approach the moving module 11, thereby causing the two traction blocks 32 in the rotating shaft forming assembly 3 and the drive blocks 33 in the two alignment mechanisms to move synchronously, thereby forcing the two side forming blocks 31 and the inner forming blocks 34 in the two alignment mechanisms to move towards the corresponding base block 35 and approach each other until the end of each rectangular insert 341 is in contact with the end of the corresponding rectangular insert 311. At this time, each first semicircular countersunk hole 342 is joined with the corresponding second semicircular countersunk hole 312 and concentrically surrounds the corresponding core sleeve 37; each third semicircular countersunk hole 343 is joined with the corresponding fourth semicircular countersunk hole 313, and each first semicircular notch 344 is joined with the corresponding second semicircular notch 314.

[0044] Subsequently, the molten material enters between each trapezoidal moving mold cavity 131 and its corresponding counterpart through the gate in the feed block 12 and the runner in the moving mold 11. After cooling, four rotating sliders are formed (existing technology).

[0045] Then, the feeding block 12 is driven forward by the action mechanism to move away from the moving module 11. Similarly, the two side forming blocks 31 and the inner forming blocks 34 in the two alignment mechanisms are reversed and reset. Then, the moving module 11 is driven forward by the action mechanism to move away from the feeding block 12, which in turn causes the moving mold core 13 to separate from the fixed mold core 24. Finally, the four rotating sliders after forming are ejected forward by the ejection mechanism 23 (existing technology).

[0046] This invention utilizes a rotating shaft forming component 3 to form the hollow pin on the rotating slider of an automobile without using any linear motion devices such as cylinders, thereby significantly reducing the manufacturing cost of the mold; moreover, it can form four rotating sliders of an automobile at once, thereby effectively improving production efficiency.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
