After the original drawing die is placed in the additive mold, vacuum feeding is required when adding molten resin. This can avoid the existence of bubble gaps between the molten resin and the original drawing die after molding. However, the interior of the additive mold is in a vacuum state. After the internal resin is molded, the molded structure fits into the interior of the additive mold and is not easy to remove, which is time-consuming and labor-intensive.

[0051] Step three: After the molten resin is butt-jointed with the drawing die, the compacting cover 2 is removed from above, and then the air compressor 1106 is started. The air compressor 1106 introduces compressed gas into the ventilation pipe 1104, and the compressed gas flows into the middle ventilation groove 1116. With the continuous injection of compressed gas, the embedded circular plate 1101 gradually pushes the molded object above. When the embedded circular plate 1101 is pushed upward a specified distance, the diverter channel 1117 is connected to the inside of the mold body 1, and the compressed gas is continuously injected into the mold body 1 through each diverter channel 1117. The injection of compressed gas realizes multi-angle and multi-directional lifting, thereby lifting the molded object from the mold body 1 a specified distance, and the staff collects it and ends the operation.
