[0014] A method for injection molding plastic parts of automobile parts comprises the following steps: Step 1: Mold installation: The staff installs the lower mold and the upper mold on the top side of the movable component and the bottom of the movable top plate respectively through external equipment and bolts; Step 2: Mold positioning: The main controller controls the lifting platform of the injection molding table to drive the movable top plate to move downward, thereby driving the lower mold and the upper mold to perform a trial mold closing action. Here, the light matrix is ​​irradiated and sensed by the light sensors on the sides of the movable top plate and the movable base plate, and the main controller determines the deviation state of the lower mold and the upper mold according to the sensor data of the two groups of light sensors; Step 3, horizontal adjustment of the trial mold closing; in the trial mold closing action, the side surface of the upper mold is set on the circular hole plate body to cover and squeeze the concave block downward and make it contact and slide with the tapered block. Here, the slide bar on the concave block slides into the hole groove of the tapered block, and then the sensor data of the light sensor is used to control the internal coil of the hole groove on the side where the mold is deviated to be energized. Since the tapered block and the concave block are in a rotating state when working, the internal coil of the hole groove is energized one by one and then all of them are energized. Control mode; thereby achieving the closing of the lower mold and the upper mold During the molding process, the coil inside the hole groove that deviates to one side absorbs the slide bar, and then the micro motor drives the conical block to rotate, so that the slide bar outside the concave block is realized inside the circular hole plate body on the side of the upper mold. The slide bar on the deviated side remains in a fixed state and pushes the lower mold and the movable base plate to move to the deviated side. Here, the adjustment component performs the adjustment action synchronously, and the slide bar away from the deviated side remains in a sliding state.

Finally, all the slide bars are energized and remain in an extended state to ensure that the circular hole connecting plate on the side of the upper mold and the conical block are in a concentric circle state; Step 4: Trial mold level adjustment; when the adjustment components synchronously perform the adjustment action, the main controller controls the adjustment parts to perform up and down adjustment actions under the monitoring of the pressure sensor, thereby driving the height of the lower mold to be controlled singly, and the lower mold is adjusted and parallel to the upper mold under the monitoring of the horizontal detector. Here, since the fixed screw barrel is respectively connected to the bolts of the movable base plate and the lower mold, the fixed screw barrel rotates inside the limit ball with the adjustment action of the movable base plate and the lower mold. After the adjustment is completed, the coil is energized to adsorb the rotating ball to ensure that the lower mold is fixedly installed at a certain angle; Step 5, mold closing test; the movable top plate is driven downward by the lifting platform of the injection molding table to drive the lower mold and the upper mold to perform mold closing action, and then the gas is injected through the injection port through the external equipment to perform pressure test on the density and strength of the mold closing, and the heat-conducting thermal oil is introduced into the diverter valve through the collecting valve through the external pipeline by the main controller, and the heat-conducting oil is input into the pressure-stabilizing valve through the diverter valve and the bifurcated pipe for buffering, and then the heat-conducting oil is input into the internal cavity of the movable base plate through the connecting pipe, and the connecting plate, the electric refrigeration plate and the heat-conducting colloid are driven to rotate through the linkage parts, so that the connecting plate drives the cooling end and the heating end of the electric refrigeration plate to face the inner cavity flow channel of the heat-conducting plate respectively, and the heat-conducting oil in the inner cavity flow channel of the heat-conducting plate can be slightly adjusted by 1-3 degrees Celsius through the precision temperature control effect of the electric refrigeration plate, and the heat inside the lower mold and the upper mold is efficiently exchanged, which is conducive to using the high thermal conductivity of the heat-conducting oil to perform micro-temperature control on the lower mold and the upper mold; Step 6: close the mold again for injection molding; introduce the injection material through the injection port via external equipment into the lower mold and the upper mold for pressure molding, and repeat the test process of the movable base plate and the cooling component in step 4 to micro-control the internal temperature of the lower mold and the upper mold in order to improve the injection molding effect and reduce the formation of injection bubbles.

The lower mold is adjusted and parallel to the upper mold by controlling the up and down adjustment action of the adjusting member, thereby ensuring that the lower mold is fixedly installed at a certain angle. The electric cooling plate is driven to rotate by a linkage member so that its cooling end and heating end face the inner cavity flow channel of the heat conduction plate body respectively. Then, the temperature of the thermal oil in the inner cavity flow channel of the heat conduction plate body can be slightly adjusted by the precise temperature control effect of the electric cooling plate, thereby facilitating the use of the high thermal conductivity of the thermal oil to perform micro-temperature control on the lower mold and the upper mold, thereby improving the injection molding effect and reducing the formation of injection molding bubbles.
