The invention discloses a sidewall-opened type deep hole structure. The sidewall-opened type deep hole structure comprises a hole side wall, wherein structures for preventing materials from flowing through the hole sidewalls are arranged onthe hole sidewalls of two opposite sides. The invention also discloses a mold of the sidewall-opened type deep hole structure; the mold comprises a deep hole structure cavity; a flow prevention hole forming block used for forming flow prevention holes is respectively arranged on each of two sides of the sidewall of the deep hole structure cavity. The invention also discloses an injection molding method of the mold. The injection molding method of the mold comprises the following steps: adjusting a material flow direction to enabling two flow prevention hole forming blocks to be respectively arranged on two sides of the material flow direction; firstly gathering a material flow (1) and a material flow (2), then flowing downwards to form a material flow (3) and a material flow (4), gathering the material flows in the bottom of the deep hole structure cavity, and discharging air from an air discharging mechanism of the bottom of the deep hole structure cavity. By adopting the sidewall-opened type deep hole structure, the air marks on the surfaces of products near the deep hole structure and other appearance defects can be solved; products with attractive appearance can be prepared; the satisfaction of customers is realized; products are successfully produced in batches. The deep hole structure and the mold of the deep hole structure are simple in structure and liable to implement; only little cost is increased.
