[0002] Building block toys are toys that assemble multiple building blocks together to form different types of children's buildings, which can realize the creativity of the builder and let children experience the experience and fun of building a house. In recent years, various building toys with different specifications and designs have been introduced one after another.

[0003] The common building toy module is a large toy brick, which is the basic component for building. In the prior art, the large toy brick usually has different through holes dug on the surface of a brick and is combined with connecting pieces to complete the splicing of the large bricks. However, the structure of the existing large toy brick itself is relatively simple. Some also use male and female molds to be molded in a matching manner, but the connection structure between the male and female molds is not reasonably designed, resulting in easy misalignment of the openings between the male and female molds, affecting subsequent use and assembly. Secondly, the inner cores of the male and female molds used are prone to glue overflow during the glue injection process, affecting both aesthetics and use. Summary of the Invention

After the glue injection is completed, the excess water will be injected into the runner holes 112 to form a connecting component 32 connecting the two sides of the flexible outer shell, preventing the surface of the flexible outer shell from shifting on the surface of the large brick body.

[0063] A slot 213 is dug on the side of the bottom surface of the male module facing away from the inner cavity. The slot is located above the convex shaft 29. Horizontal and vertical partitions 214 are arranged in the slot. A cover plate 212 is covered on the top of the slot 213 to prevent watering from seeping into the slot.

[0064] The submarine gate insert 40 is designed for convenient injection molding and is not a product. The submarine gate is a form of injection molding and a way for plastic to enter the mold cavity on the mold. In the injection molding process of the flexible shell of the above-mentioned large toy brick, after the male module and the female module are combined to form an injection mold, first, the molten plastic melt is injected into the mold cavity of the injection mold formed by the combination of the male module and the female module through an injection molding machine. Usually, the plastic melt enters the mold cavity from the injection port. In this embodiment, the plastic melt enters the submarine gate insert 2 through the runner hole on the submarine gate insert 40 and enters the injection port on the female module through the gate runner in the submarine gate insert 2, and then the combing solution is injected into the injection mold cavity. After that, wait for the large toy brick to cool and form. After cooling and forming, open the mold, and then the injection molding of the flexible shell is completed.
