Description
Technical Field
[0001] This utility model relates to a molding die for the air vent blades of an automotive sub-dashboard. Background Technology
[0002] The air vent blades are an important component of the car's air conditioning system. Their main function is to distribute and adjust the direction and angle of the airflow. The air vent blades are usually located in the instrument panel or similar positions. By controlling the opening or closing of these blades, the airflow direction can be adjusted in different directions. The air vent blades are usually composed of horizontal blades, knobs, knob bases, and knob forks, and each component is made of plastic.
[0003] Since the air outlet blades are plastic components, their production relies on matching injection molds and injection molding machines. Because the air outlet blades are small in size, one set of injection molds can mold each component of the air outlet blades simultaneously. However, if the mold adopts a "one-out-one" structure, its size is too small and does not match the injection molding machine station. If a "one-out-two" structure is adopted, although the size increases, the thinness of the air outlet blades will affect the flowability of the molten material, thus increasing the defect rate of the air outlet blades. Therefore, only a "one-out-one" structure can be used and a smaller injection molding machine can be purchased to adapt to it, which increases production costs and has low production efficiency, and needs further improvement. Utility Model Content

The feeding guide module includes a first guide strip 19 and a second guide strip 110.

[0044] Working principle:
[0045] The end plate 3 and the base plate 2 are respectively installed on the action mechanism and the machine body of the injection molding machine. The action mechanism drives the end plate 3 to move backward, and then the flow divider 15 in each main body 1 drives the moving template 11 to move towards the fixed template 12 until the two are joined together (existing technology).
[0046] During the movement of the moving template 11, the first traction rod 172 in each first molding component 17 will move synchronously, thereby forcing each first slider 171 to move towards the first molding cavity 141 until the first limiting strip 1731 on each first locking block 173 is inserted into the bottom of the corresponding first groove 143; similarly, the second traction rod 182 in each second molding component 18 will also move synchronously, thereby forcing each second slider 181 to move towards the second molding cavity 144 until the second limiting strip 1831 on each second locking block 183 is inserted into the bottom of the corresponding second groove 147.
[0047] When the end face of the movable mold core 13 and the end face of the fixed mold core 14 are joined together, the two protruding rings 131 extend into the interior of the two first forming cavities 141 respectively, and the two third forming cavities 136 on the movable mold core 13 are joined with the two second forming cavities 144 respectively. At this time, the two protrusions 132 on the movable mold core 13 extend into the two recesses 142 respectively, and the protrusions 145 on each second forming cavity 144 extend into a corresponding fourth forming cavity 137 and a notch 135.
[0048] Next, the molten material enters the manifold 15 in each body 1 through the gate in the end plate 3, and then enters the first molding cavity 141, the second molding cavity 144, the pit 142, the fourth molding cavity 137 and the notch 135 through the gating channel in the manifold 15. After cooling, the corresponding components that make up the air outlet blade are formed. Then, the end plate 3 is driven to move forward by the action mechanism, and in the same way, the moving template 11 in each body 1 moves forward and leaves the fixed template 12. Finally, the ejection mechanism 16 in each body 1 ejects each component that makes up the air outlet blade forward (existing technology).
[0049] This invention features two main bodies 1 for forming air outlet blades between the end plate 3 and the bottom plate 2. Each main body 1 can simultaneously form each component of the air outlet blades, thus achieving a "one-outlet-two-outlet" structure. This increases the overall mold volume to accommodate conventional injection molding machine specifications, thereby reducing production costs and improving production efficiency. Furthermore, the "one-outlet-two-outlet" structure of this invention differs from the traditional "one-outlet-two-outlet" structure. The two main bodies 1 are independent of each other and do not interfere with each other. Therefore, the "one-outlet-two-outlet" structure does not affect the fluidity of the molten material, thus effectively avoiding an increase in the molding defect rate.
[0050] 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.
