The basic introduction of the instruments of different cars is different, but the conventional instruments of general cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. When the existing car dashboard is produced using molds, it is necessary to melt the plastic and pour it into the mold, then pour it into the mold for molding and cooling, and then take out the product. At the same time, when the surface of the dashboard is damaged, the surface can also be repaired by injection molding.

A working frame is installed above the workbench, and a driving cylinder is installed on the working frame. The front end of the driving cylinder is connected to a servo motor through a telescopic guide column. The front end of the servo motor is connected to a fixed sliding column installed on the working frame through a sliding plate. The driving cylinder can be used to adjust the working position of the servo motor, so that the injection molding head installed at the front end of the extrusion screw can be conveniently connected to the discharge port to realize quantitative push injection molding. The interior of the extrusion blow molding bin is sealed with a high-pressure air pump through an air pipe. A pressure gauge is installed on the upper end of the extrusion blow molding bin. The high-pressure air pump can pressurize the extrusion blow molding bin, so as to realize quantitative blow molding of hot-melt plastics by high pressure. At the same time, the pressure gauge is used to monitor the air pressure value in the bin in real time. However, the following problems still exist in the actual use of this patent: Although the gas high-pressure molding machine for the production of automobile instrument plastic sheets can be used to adjust the working position of the servo motor by driving the air cylinder, so as to facilitate the docking of the injection molding head installed at the front end of the extrusion screw with the discharge port and realize quantitative push injection molding, the rotation of the extrusion screw cannot accurately control the amount of injection molding raw materials discharged, resulting in a waste of raw materials during injection molding. At the same time, some raw materials will remain at the discharge port, causing raw materials to drip and affect the accuracy of injection molding.

The injection molding raw materials can be injected into the heating injection barrel 116 through the serpentine elbow 203 and the installation pipe 204 through the pump body 202 to heat and mix the raw materials.

[0026] Working principle: Before using this kind of car dashboard surface treatment device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11 As shown, first, the raw material for injection molding is poured into the grinding box 211, and the adjusting motor 213 is used to drive the adjusting threaded rod 214 to rotate, so that the adjusting threaded bracket 217 drives the adjusting sliding rod 218 and the fixed bracket 219 to move up and down, and the distance between the grinding cone 222 and the grinding box 211 is adjusted, so as to control the grinding fineness of the injection molding raw material, and the grinding motor 220 drives the grinding connecting shaft 221 and the grinding cone 222 to rotate, so as to realize the grinding of the injection molding raw material, and the mixing motor 206 is started to drive the mixing spiral blade 207 to rotate, so as to realize the full mixing of the injection molding raw material, and the mixing spiral blade 207 is used to drive the tripod 208 and the cleaning spiral blade 209 to rotate, so as to clean the inner wall of the mixing box 201, avoid the residual injection molding raw material on the inner wall of the mixing box 201, thereby causing the phenomenon of waste of raw materials, and the injection molding raw material can be injected into the heating injection barrel 116 through the serpentine elbow 203 and the mounting pipe 204 through the pump body 202 to heat and mix the raw material.

[0027] Secondly, the injection motor 117 is used to drive the injection rotating rod 118 and the injection spiral blade 119 to rotate, so as to fully mix the injection molding raw materials inside the heated injection barrel 116, so that the raw materials inside the heated injection barrel 116 can be fully heated and melted. By reversely starting the injection motor 117, the injection molding raw materials can be injected into the injection pipe 120 through the one-way valve 121 at the bottom under the action of the injection spiral blade 119. Since the volume of the injection spiral blade 119 is large, the injection molding using the injection spiral blade 119 can quickly perform injection repair on the damaged car dashboard, thereby improving the efficiency of injection molding. When it is necessary to repair the damaged car dashboard, in order to avoid wasting the injection molding raw materials, the injection cylinder 125 can be used to drive the plunger 126 to slide inside the injection pipe 120. The speed of the movement of the plunger 126 can be controlled to allow the injection molding raw materials to flow out slowly, which is convenient for accurate repair of the dashboard. When the plastic material is ejected from the injection pipe 120, under the action of pressure, the rotating shaft 134 drives the closed baffle 135 to rotate, and the injection material flows out through the gap between the closed baffles 135. Since the closed baffle 135 rotates a certain angle, the entire closed baffle 135 generates a spiral rotation force, thereby driving the entire closed baffle 135 and the rotating connecting rod 133 to rotate. The rotating connecting rod 133 drives the second bracket 136, the connecting block 137 and the spiral cleaning plate 138 at the bottom to rotate, thereby cleaning the outer surface of the injection nozzle 131 to prevent the injection nozzle 131 from adhering to a certain amount of injection material, thereby causing a waste of material. When the injection molding is stopped, under the elastic force of the closing spring 129, the closing clamping ring 130 pushes the closed baffle 135, so that the closed baffle 135 rotates to the bottom of the injection nozzle 131 to close the injection nozzle 131, thereby preventing the injection material from dripping and affecting the accuracy of the injection molding.

[0028] Finally, the lifting motor 104 drives the first sprocket transmission assembly 105 and the lifting threaded rod 106 to rotate, so that the lifting threaded sleeve 107 and the lifting sliding sleeve 109 drive the lifting plate 108 to move up and down, so that the heated injection barrel 116 and the injection nozzle 131 can be moved to the top of the car dashboard to achieve precise injection molding. The rotating motor 113 drives the rotating worm 114 to rotate. By utilizing the meshing connection between the rotating worm 114 and the heating worm wheel 115, the injection molding material inside the heated injection barrel 116 can be quickly heated to improve the fluidity of the injection molding material. The clamping motor 141 drives the second sprocket transmission assembly 142 and the clamping bidirectional threaded rod 143 to rotate, so that the second clamping bracket 144 drives the first supporting bottom plate 145 and the supporting side plate 146 to move relative to each other. By rotating the adjusting bolt 147, car dashboards of different sizes can be clamped and fixed, thereby improving the repair stability of the car dashboard.
