Injection mold with buffer channel for automotive dashboard

The utility model discloses an injection mold with a buffer channel for an automotive dashboard. The injection mold comprises an upper mold, a lower mold matched with the upper mold, and a pouring gate structure penetrating through the upper mold and the lower mold, wherein the upper mold is composed of a male mold and an upper bottom plate; a positioning column is arranged at the bottom of the male mold; the male mold is provided with a core; the core is provided with a small hole; the small hole is communicated with the pouring gate structure; the lower mold is composed of a female mold and a lower bottom plate; a positioning hole matched with the positioning column is formed in the upper surface of the female mold; a cavity is formed in the position, corresponding to the core, on the female mold; the pouring gate structure comprises a main runner and a sub-runner; the buffer channel is arranged between the main runner and the sub-runner. By virtue of the cooperation of the positioning column and the positioning hole, the cooperation accuracy of the upper mold and the lower mold can be effectively improved; by additionally arranging the buffer channel between the main runner and the sub-runner, when a fluid enters the buffer channel, the flow speed and pressure of the fluid can be well reduced, the forming probability of a punching mark of a transparent injection molding piece is reduced, the structure is simple and practical, and the production efficiency is improved.
