Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.
Fig. 1 and fig. 2 are schematic structural diagrams of two embodiments of the present invention.
The embodiment of the utility model provides a computer mouse injection mold's gas-assisted injection structure, including last mould 1 and lower mould 2 of mutually supporting, go up the cooperation between mould 1 and the lower mould 2 and be equipped with the identical shaping chamber 3 with the product shape. Go up mould 1 and be equipped with injection hole 4 and air inlet duct 5, be equipped with between injection hole 4 and the shaping chamber 3 and mould plastics the material way 6, the one end and the trachea 7 of air inlet duct 5 are connected, the other end and the shaping chamber 3 intercommunication. The lower die 2 is provided with an exhaust duct 8, one end of the exhaust duct 8 is communicated with the outside, and the other end of the exhaust duct is communicated with the molding cavity 3. A temperature adjusting cavity 9 is arranged in the lower die 2. The upper die 1 or the lower die 2 is provided with an overflow groove 16 at one side of the molding cavity 3.
In the first embodiment, as shown in fig. 1, one end of the temperature adjusting cavity 9 is communicated with the water chilling unit through a water inlet pipeline 10, and the other end of the temperature adjusting cavity 9 is communicated with a water outlet pipeline 11. The water inlet pipeline 10 and the water outlet pipeline are both provided with one-way water valves 14.
In the second embodiment, as shown in fig. 2, one end of the temperature adjusting cavity 9 is communicated with the air cooler through an air inlet pipe 12, and the other end of the temperature adjusting cavity 9 is communicated with an air outlet pipe 13. The air inlet pipeline 12 and the air outlet pipeline are both provided with one-way air valves 15.
In two embodiments of the present invention, the upper mold 1 is a movable mold, and the lower mold 2 is a fixed mold. An air inlet groove is arranged on the upper die 1.
