[0023] The diaphragm positioning assembly 9 includes two groups of mounting plates 92, one side of the two groups of mounting plates 92 is fixedly connected to two groups of connecting frames 91, the other side of the two groups of mounting plates 92 is fixedly connected to a side plate 93, one side of the side plate 93 is fixedly connected to a positioning plate 94 arranged parallel to the mounting plate 92, and both sides of the movable mold 8 are fixedly connected to multiple groups of guide blocks 16, and the opposite side of the two groups of side plates 93 is provided with a slide groove 95 for the sliding connection of the guide block 16.

[0024] The reset component 10 includes a telescopic sleeve rod 101 and a reset spring 102. The reset spring 102 is sleeved on the outer side of the telescopic sleeve rod 101. One end of the telescopic sleeve rod 101 is fixedly connected to the other side of the mounting plate 92. The reset spring 102 facilitates the reset of the position of the positioning plate 94, thereby facilitating the rapid positioning of the diaphragm and improving the stability of the diaphragm.

[0025] The lower surface of the movable mold 8 is fixedly connected to a support bottom plate 17. A groove is provided on the upper surface of the support bottom plate 17. The support bottom plate 17 facilitates the support of the diaphragm before positioning, thereby improving the stability of the diaphragm positioning.

[0026] One side of the movable mold 8 adjacent to the two side grooves 15 is provided with a convex plate 13. A plurality of air holes 14 are provided on one side of the convex plate 13. The movable mold 8 is hollow. A gas guide pipe 12 is provided on the side of the movable mold 8 opposite to the convex plate 13. The gas guide pipe 12 is used to evacuate the air in the movable mold 8, thereby adsorbing the diaphragm by negative pressure. The convex plate 13 fits with the fixed mold 7 to ensure the fitting degree of the product and the diaphragm, thereby improving the forming quality of the product. At the same time, the stability of the diaphragm is improved by the plurality of air holes 14, further ensuring the fitting effect of the product and the diaphragm.

[0027] A square hole for the convex plate 13 to be embedded is provided on one side of the fixed mold 7. An injection pipe 11 communicated with the square hole is provided on the other side of the fixed mold 7. The injection pipe 11 is used to facilitate injection molding and improve the fusion quality of the product and the diaphragm.

The width of the positioning plate 94 is larger than the width of the mounting plate 92. The cross-section difference between the positioning plate 94 and the convex plate 13 is used to facilitate the positioning of the diaphragm and improve the stability of the diaphragm positioning.

[0030] When in use, the operator presses the connecting frame 91 to make the mounting plate 92 drive the side plate 93 to move, and at the same time the guide block 16 slides along the slide groove 95, and the mounting plate 92 compresses the return spring 102 on the telescopic sleeve rod 101, increasing the elastic potential energy of the return spring 102, and then places the diaphragm on the groove of the supporting base plate 17. During the placement process, the diaphragm passes through the gap between the positioning plate 94 and the convex plate 13, and the groove edge of the supporting base plate 17 can prevent the diaphragm from falling off. The operator releases the pressure on the connecting frame 91, and in multiple groups The elastic action of the return spring 102 drives the positioning plate 94 close to the movable mold 8, so that the positioning plate 94 presses the edge of the diaphragm to prevent the diaphragm from detaching, and then uses the external air pump connected to the air guide pipe 12 to extract the air in the movable mold 8, and uses the negative pressure to make the suction hole adsorb the diaphragm, thereby improving the stability of the diaphragm on the movable mold 8. The cylinder 4 is started to drive the movable mold 8 close to the fixed mold 7 to close the mold, and then injection molding is carried out through the injection molding tube 11. After molding, the diaphragm is fused with the product, and finally the mold is separated to form a pattern on the surface of the product.
