Figure 3 As shown, the injection molding tube 23 is provided with an arc surface on one side close to the shielding thin plate 29, which is convenient for stretching out the two sets of mutually attracted shielding thin plates 29, and a guiding arc surface is provided on the surface where the shielding thin plate 29 and the injection molding tube 23 contact each other, which is convenient for cooperating with the arc surface on one side of the injection molding tube 23, so that the injection molding tube 23 can stretch out the shielding thin plates 29; when one end of the injection molding tube 23 is movably inserted into the docking hole on one side of the lower mold assembly 1, the shielding thin plate 29 is supported by the injection molding tube 23 and moves along the storage groove 30, and the top of the shielding thin plate 29 will contact the bottom of the linkage plate 28 and support the linkage plate 28 and rotate. The rotation of the linkage plate 28 drives the linkage plate 1 27 to rotate under the action of the linkage rod 26, and the linkage plate 28 rotates.

Under the holding action of the elastic plate 14, the pressure plate 13 no longer presses down the top of the ejector rod 20, and the holding ball 19 retracts into the receiving groove 18 under the elastic force of the compression spring 22. Figure 3The bottom of the shielding sheet 29 is at a certain distance from the bottom of the fixing seat 4 to ensure that after the bottom end of the top holding ball 19 leaves the top holding groove 24, the injection tube 23 is separated from the side of the lower mold assembly 1, and the bottom of the shielding sheet 29 will extend from the bottom of the fixing seat 4, so that the bottom of the shielding sheet 29 will not affect the separation of the injection tube 23 from the docking hole on the side of the lower mold assembly 1.

[0038] The working principle and use process of the present invention are as follows: the injection molding equipment 33 injects the molten material into the casing mold cavity of the upper mold assembly 35 and the lower mold assembly 1.

Then the injection molding rotating platform 36 drives the lower mold assembly 1 to rotate to the material taking device 37, and the shaped casing is taken out by the material taking device 37, and the shaped casing is transferred to the next processing position, and this reciprocating process is repeated to complete continuous production; when using the lower mold assembly 1, the injection molding equipment 33 is started to slide and drive the injection molding tube 23 to approach the shielding thin plate 29, refer to Figure 3 As shown, the injection molding tube 23 is provided with an arc surface on one side close to the shielding thin plate 29, which is convenient for stretching out the two sets of mutually attracted shielding thin plates 29, and a guiding arc surface is provided on the surface where the shielding thin plate 29 and the injection molding tube 23 contact each other, which is convenient for cooperating with the arc surface on one side of the injection molding tube 23, so that the injection molding tube 23 can stretch out the shielding thin plates 29; when one end of the injection molding tube 23 is movably inserted into the docking hole on one side of the lower mold assembly 1, the shielding thin plate 29 is supported by the injection molding tube 23 and moves along the storage groove 30, and the top of the shielding thin plate 29 will contact the bottom of the linkage plate 28 and support the linkage plate 28 and rotate. The rotation of the linkage plate 28 drives the linkage plate 1 27 to rotate under the action of the linkage rod 26, and the linkage plate 28 rotates. The movable plate 27 rotates to press the connecting plate 15 downward; at the same time, the servo motor is started to drive the rotating rod 2 to rotate, and the rotating rod 2 rotates to drive the limiting long plate 3 to rotate until the semicircular plate 3-2 is in active contact with the outer ring surface of the sliding rod 11. The sliding rod 11 is supported by the semicircular plate 3-2 and moves along the sliding groove 12. The movement of the sliding rod 11 drives the connecting plate 9 to move toward the top of the fixed seat 4, which can drive the pressing plate 13 to rotate and press the ejector rod 20 downward at the same time. During the downward pressure of the ejector rod 20, the bottom end of the holding ball 19 will be movably inserted into the holding groove 24, thereby strengthening the fixation of the injection tube 23, improving its sealing effect, and preventing the molten material from overflowing or external impurities from entering the mold during the injection molding process.
