[0003] In the process of injection molding automotive dashboards, we have found that traditional injection molds typically use a single-point injection method. Due to the irregular shape of automotive dashboards, this method not only affects injection efficiency but also easily leaves marks on the surface of the molded dashboard, impacting product quality. To address these issues, we designed a multi-point injection and mark-free surface filling mechanism for automotive dashboard injection molds. Summary of the Invention

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-4 As shown, the multi-point injection surface filling mechanism for automotive dashboard injection molding of this utility model includes a lower fixed plate 1 and an upper fixed plate 5. Support plates 2 are fixedly installed on both sides of the top of the lower fixed plate 1. A lower mold base 3 is fixedly installed on the top of the support plates 2. A connecting seat 6 is fixedly installed at the bottom of the upper fixed plate 5. An upper mold base 4 that is adapted to the lower mold base 3 is fixedly installed at the bottom of the connecting seat 6. A cavity 17 is opened inside the connecting seat 6. An injection channel 13 is fixedly installed inside the cavity 17. Multiple dispensing nozzles 16 are fixedly installed at the bottom of the injection channel 13. An electric control valve 14 is fixedly installed at the connection between the multiple dispensing nozzles 16 and the injection channel 13.

[0020] Specifically, by providing an injection channel 13 inside the connector 6 and connecting multiple nozzles 16 through the injection channel 13, and by providing an electronically controlled valve 14 between the nozzles 16 and the injection channel 13, not only can multi-point synchronous injection be achieved, but the injection rate can also be ensured, thereby achieving seamless injection molding of the automotive dashboard surface and improving the product quality of the automotive dashboard.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a horizontal rolling cutter with a cleaning component. A cooling water pipe 15 is fixedly installed on the side wall of the cavity 17, and cooling water nozzles 8 that communicate with the cooling water pipe 15 are fixedly provided on both sides and the sides of the connecting seat 6.

[0022] Specifically, the cooling water pipe 15 can improve the cooling efficiency of the car dashboard.

[0023] A glue inlet 7 is fixedly provided at the center of the upper fixed plate 5, and the glue inlet 7 is connected to the glue injection channel 13.

[0024] Specifically, the setting of the inlet nozzle 7 ensures that the molten adhesive flows from the inlet nozzle 7 into the dispensing channel 13.

[0025] Both sides and the edges of the upper mold base 4 are fitted with core-pulling reset blocks 9. The bottom of each core-pulling reset block 9 is fixedly installed with a stroke controller 10. The end of each core-pulling reset block 9 is fixedly connected with an insert 11.

[0026] Specifically, through the cooperation of the stroke controller 10 and the core-pulling reset block 9, the upper mold base 4 and the lower mold base 3 are separated to achieve oblique pull demolding.

[0027] Positioning guide posts 12 are fixedly provided at the four corners of the top of the lower mold base 3, and positioning guide holes that are adapted to the positioning guide posts 12 are fixedly provided at the four corners of the bottom of the upper mold base 4.

[0028] Specifically, the positioning guide post 12 and the positioning guide hole work together to improve the accuracy of the mold closing between the lower mold base 3 and the upper mold base 4.

[0029] At least two lifting rings are fixedly provided on each of the four sides of the lower mold base 3 and the upper mold base 4.

[0030] Specifically, the lifting rings facilitate the hoisting, assembly, and disassembly of the lower mold base 3 and the upper mold base 4 with the injection molding machine.

[0031] The working principle of this utility model is as follows: When using the injection molding mold for an automotive dashboard, the mold is first installed in the injection molding machine, and the cooling water nozzle 8 is connected to the external water pipe through a connecting hose. After the upper mold base 4 and the lower mold base 3 are closed, the molten adhesive from the injection molding machine flows into the injection channel 13 through the injection nozzle 7. Then, the corresponding electric control valve 14 is opened by the controller of the injection molding machine. When the electric control valve 14 is opened, the adhesive inside the injection channel 13 flows into the mold cavity through the corresponding outlet nozzle 16, realizing multi-point injection. This allows for rapid filling of the automotive dashboard mold cavity, replacing the traditional single-point injection, achieving seamless injection molding of the automotive dashboard surface, and improving the product quality of the automotive dashboard.
