Description
Technical Field
[0001] This utility model relates to a connector injection molding die. Background Technology
[0002] A gas stove flameout protection device is a safety device that automatically cuts off the gas supply. Its core function is to quickly cut off the gas supply when the flame is accidentally extinguished, preventing leaks from causing fires or carbon monoxide poisoning. In order to connect with the gas pipeline, the gas stove flameout protection device is equipped with a connector for sealing the connection to the gas pipeline. Since the connector is made of plastic, its production relies on matching molds and injection molding machines.

[0044] Working principle:
[0045] An end plate 5 is fixed to the front side of the flow divider block 4, and a bottom plate 6 is fixed to the rear side of the fixed mold plate 2. An ejection mechanism 7 is set between the bottom plate 6 and the fixed mold plate 2. The end plate 5 and the bottom plate 6 are then installed on the action mechanism and the machine body of the injection molding machine, respectively. The action mechanism drives the end plate 5 to move backward, and the flow divider mechanism drives the moving mold plate 8 to move towards the fixed mold plate 2 until the two are joined together, so that the moving mold core 9 and the fixed mold core 10 in each molding mechanism fit together (existing technology). At this time, the opening of each first groove 91 is joined with the opening of a corresponding second groove 104. The end face of each first separation block 98 is attached to the end face of a corresponding third separation block 105. The end face of each second separation block 97 is attached to the end face of a corresponding fourth separation block 101. The two limiting blocks 107 on each fixed mold core 10 are respectively embedded in the two limiting notches 94 on the corresponding moving mold core 9.
[0046] As the moving template 8 moves backward, it drives each first traction rod 92 in each side forming component 11 to move synchronously, thereby forcing the side sliders 111 in each side forming component 11 to move toward the fixed mold core 10. This causes each positioning block 1115 on the side slider 111 to be inserted into a corresponding first notch 96 and a corresponding second notch 102, and causes the stop block 1116 on each positioning block 1115 to be embedded between a corresponding first groove 91 and a corresponding second groove 104.
[0047] Subsequently, the molten material enters the front opening of the feed seat 16 in the flow distribution mechanism through the gate in the end plate 5, then enters the four flow distribution nozzles 15 in each flow distribution nozzle assembly through the flow distribution block 4, and then enters the two flow distribution grooves 121 on the flow distribution strip 12 on the corresponding moving mold core 9 through each seat sleeve 18, and then enters the space between each first groove 91 and the corresponding second groove 104 through each first feed hole 122 and the corresponding second feed hole 99. After cooling, eight connectors can be formed simultaneously. Then, the end plate 5 is driven forward by the action mechanism, and the moving mold plate 8 is driven forward and away from the fixed mold plate 2 in the same way, so that each moving mold core 9 leaves the corresponding fixed mold core 10. Finally, the ejection mechanism 7 ejects all eight formed connectors forward (existing technology).
[0048] This invention significantly improves the flow distribution effect of molten material, thereby expanding the range that the molten material can uniformly cover while ensuring good fluidity. As a result, the number of connectors can reach "one out of eight" in a single injection molding process, thus breaking through previous limitations and further improving production efficiency.
[0049] 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.
