[0016] By Figs. 1-2 Be provided, the utility model discloses a base 1, be provided with lower mould 2 on base 1, and lower mould 2 is connected with upper mould 5, and lower mould 2 is opened with forming groove 3 on, and upper mould 5 is provided with forming boss 6, and forming boss 6 is matched with forming groove 3, and lower mould 2 is opened with injection port 8, and injection port 8 is communicated with forming groove 3, and the edge of forming groove 3 is provided with primary exhaust groove 9, and the edge of primary exhaust groove 9 is provided with secondary exhaust groove 10, and primary exhaust groove 9 is connected with secondary exhaust groove 10 through exhaust passage 11, and lower mould 2 is provided with exhaust pipe 12, and exhaust pipe 12 is connected with secondary exhaust groove 10.

[0017] The depth of primary exhaust groove 9 is 0.03mm, and the width is 1.5mm, and the relatively shallow depth can prevent molten material from overflowing, while allowing gas to be smoothly discharged, and the depth of secondary exhaust groove 10 is 0.08mm, and the width is 4mm, and the relatively deep depth and the relatively large width can accommodate more gas and quickly discharge it through exhaust passage 11 and exhaust pipe 12.

[0018] Lower mould 2 is provided with guide column 4, and upper mould 5 is provided with guide slot 7, and guide slot 7 is matched with guide column 4, and lower mould 2 is connected with upper mould 5 through guide column 4, to ensure that upper mould 5 and lower mould 2 are accurately aligned when the mould is closed, avoiding misalignment that causes molding defects.

[0019] Exhaust passage 11 has multiple, and multiple exhaust passages 11 connect forming groove 3, primary exhaust groove 9 and secondary exhaust groove 10, and exhaust passage 11 is multiple, distributed at different positions, to ensure that gas can be quickly discharged from forming groove 3 through primary exhaust groove 9 and secondary exhaust groove 10, avoiding local gas accumulation and further reducing product defects.

[0020] The base 1 is provided with a collection box 13 connected with the end of the exhaust pipe 12, for collecting the discharged gas and a small amount of overflowed molten material, avoiding the direct discharge of the gas and molten material into the environment, and improving the cleanliness and safety of the production environment.

[0021] Working principle: When working, first, the upper mold 5 starts to move downward under the control of the machine tool to perform the mold closing operation. The guide column 4 on the lower mold 2 cooperates with the guide groove on the upper mold 5 to provide a stable basis for subsequent injection molding, avoiding product molding defects caused by mold misalignment, and ensuring the consistency and precision of product size. After mold closing is completed, the injection molding link is entered. The molten plastic or other molding material is injected into the molding groove 3 under high pressure through the injection port 8 on the lower mold 2. Since the injection port 8 is in through communication with the molding groove 3, the molten material can smoothly and quickly fill the entire molding groove 3, gradually occupying the space of the molding groove 3. During the injection molding process, the first-stage exhaust groove 9 located at the edge of the molding groove 3 starts to work. The depth of the first-stage exhaust groove 9 is 0.03 mm, and the width is 1.5 mm. The relatively shallow depth can prevent the molten material from overflowing while allowing the gas to smoothly enter the first-stage exhaust groove 9. Then, the gas entering the first-stage exhaust groove 9 enters the second-stage exhaust groove 10 through multiple exhaust passages 11. The depth of the second-stage exhaust groove 10 is 0.08 mm, and the width is 4 mm. The larger depth and width can accommodate more gas. The multiple exhaust passages 11 can make the gas quickly and uniformly exhaust from the molding groove 3 through the first-stage exhaust groove 9 and the second-stage exhaust groove 10, avoiding the local accumulation of gas and reducing product defects caused by residual gas. The gas in the second-stage exhaust groove 10 is exhausted out of the mold through the exhaust pipe 12 connected thereto. As the molten material continuously fills and flows in the molding groove 3, the product shape is gradually formed under the limitation of the mold. At the same time, the molten material gradually cools and solidifies in the mold, completing the transition from liquid to solid. Finally, an integrally molded multifunctional connecting plate product is formed in the mold cavity, effectively solving the problem of air and volatile gas not being able to be timely exhausted when the molten material fills the cavity, avoiding defects such as bubbles and pores in the product interior or surface, and significantly improving the product quality.
