Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive lamp injection molding technology, and in particular to an automotive lamp injection molding feeding device. Background Technology
[0002] With the increase in automobile production, the demand for automotive parts is also increasing. Vehicle lights refer to the lights on a vehicle, which are used to illuminate the road at night and to provide various driving signals. They are generally divided into headlights, taillights, turn signals, etc. As a type of automotive component, the demand for vehicle lights has also increased dramatically. Injection molds are required during the manufacturing of vehicle lights, and a feeding mechanism is needed to deliver the plastic material into the mold.
[0003] According to the patent application number CN 219820543 U, a rapid feeding mechanism for injection molded automotive headlight housings is disclosed, relating to the field of injection molds. The mechanism includes a feeding cylinder with a first auger nested inside. The feeding cylinder comprises an infeed head, a heat-conducting cylinder, and an outlet head. The heat-conducting cylinder is threadedly connected to the infeed head and the outlet head. A feed hopper is installed on the infeed head, and a drive motor is installed on the right side of the infeed head. The output end of the drive motor is connected to the first auger. A heat-insulating cylinder is sleeved on the outside of the heat-conducting cylinder, and a heating tube is disposed between the heat-insulating cylinder and the heat-conducting cylinder. This invention, by incorporating a first auger inside the feeding cylinder and winding a heating tube around the outside of the heat-conducting cylinder, achieves uniform delivery of the injection molding material, prevents the injection molding material from cooling and solidifying inside the feeding cylinder, and facilitates the disassembly of the heat-conducting cylinder and the outlet head for cleaning.
[0004] While the above-mentioned solution can prevent the injection plastic from cooling and solidifying inside the feeding cylinder, it is inconvenient to quantitatively output the injection plastic and has poor control over the feeding and conveying of the injection plastic. Therefore, we propose a vehicle headlight injection molding feeding device. Utility Model Content
[0005] The main purpose of this utility model is to provide a vehicle headlight injection molding feeding device, which solves the problems of inconvenience in quantitatively outputting injection molding materials and poor control effect of injection molding material feeding by setting a transmission unit and a quantitative unit.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A vehicle headlight injection molding feeding device includes a main unit, a transmission unit disposed inside the main unit, a heat preservation unit disposed on the surface of the transmission unit, and a metering unit disposed below the main unit.
[0008] The transmission unit includes a transmission shaft movably disposed inside the main unit, a helical blade mounted on the side wall of the transmission shaft, and a first drive motor mounted on the input end of the transmission shaft.
[0009] The metering unit includes a metering box installed at the output end of the main unit and communicating with the interior of the main unit, a cylindrical groove opened in the metering box, a metering element set in the cylindrical groove, a second drive motor installed at the input end of the metering element, and a discharge pipe installed at the bottom of the metering box and communicating with the cylindrical groove.
[0010] Preferably, the main unit includes a heat-conducting cylinder and a feed hopper installed on the side wall of the heat-conducting cylinder and located above the heat-conducting cylinder.
[0011] Preferably, the heat preservation unit includes a heating pipe installed on the periphery of the heat-conducting cylinder and a heat preservation cylinder installed on the periphery of the heating pipe.
[0012] Preferably, the insulation unit further includes a support base installed on the side wall of the insulation cylinder and located below the insulation cylinder.
[0013] Preferably, the metering component includes a rotating shaft movably disposed within a cylindrical groove, a storage roller mounted on the side wall of the rotating shaft, and a storage trough formed on the side wall of the storage roller.
[0014] Preferably, there are four storage troughs, and the four storage troughs are arranged in a circular array about the storage roller.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In this invention, through the transmission unit and the metering unit, when uniform delivery of injection plastic is required, the heating tube first operates to preheat the interior of the heat-conducting cylinder. Then, the injection plastic is added from the feed hopper. Subsequently, the first drive motor drives the transmission shaft to rotate, and the spiral blades can drive the injection plastic to move uniformly inside the heat-conducting cylinder, thereby achieving uniform delivery of the injection plastic. When quantitative output of the injection plastic is required, the injection plastic follows the spiral blades to the metering box, and then falls into the storage trough in the storage roller under the action of gravity. The second drive motor drives the rotating shaft to rotate, and every quarter rotation of the storage roller results in the output of injection plastic from one storage trough, thereby achieving quantitative output of the injection plastic and improving the delivery control effect of the injection plastic.
