It is to overlap multiple cavities in the mold closing direction in a mold. This mold usually has multiple parting surfaces, and one or more cavities can be arranged on each parting surface. Simply put, the stacking mold is equivalent to stacking multiple single-layer molds together and installing them on an injection molding machine for injection molding production. The characteristics of the existing stacking mold are to increase the mold parting surface without increasing the specifications of the injection molding machine to increase the number of mold cavities and improve the output of the product. The stacking mold has the advantages of high output, low production and maintenance costs, and small footprint. However, in the existing stacking injection mold, there will be residual connection between the mold and the injection port, which requires manual post-processing, affecting the production efficiency and human resources of the injection mold, and the position of the injection port may cause foreign matter in the air to stick to the injection port when not in production. Foreign matter may be brought into the mold during later injection molding, which may affect the production qualification rate of the mold. Utility Model Content

[0021] When in use, after the upper mold device 1 and the lower mold device 2 are closed, the material can be poured into the mold cavity 7 through the injection port 3. After the material is cooled in the mold cavity 7, the upper mold device 1 and the lower mold device 2 are separated, and the cooled material can be taken out from the mold shell 4. After the injection molding material is injected into the mold cavity 7 through the injection molding through hole 5, the electric telescopic rod 82 is started, and the output end of the electric telescopic rod 82 can drive the sleeve 83 to move horizontally to the left. The movement of the sleeve 83 will drive the fixed rod 84 to move. The movement of the fixed rod 84 can drive the cutting plate 85 to move.

The movement of the clamping block 94 squeezes the first spring 95. When the protective cover 92 drives the connecting block 93 to contact the upper mold device 1, the clamping block 94 is pushed to reset under the push of the first spring 95, so that the clamping block 94 can limit and fix the connecting block 93.
