[0006] In order to achieve the above-mentioned purpose, the utility model provides a mouse cover forming mold with an exhaust mechanism, comprising a base, the middle part of the upper end of the base is fixedly connected to the lower mold, the four corners of the upper end of the base are fixedly connected to columns, the top of the column is fixedly connected to a top seat, a hydraulic cylinder is installed at the middle part of the upper end of the top seat, the telescopic shaft of the hydraulic cylinder passes through the top seat and is slidably connected to the top seat, the end of the telescopic shaft is fixedly connected to a connecting seat, a plurality of connecting frames are fixedly connected to the side of the connecting seat, the bottom of the connecting frame is fixedly connected to the upper mold, and the upper mold is fitted with the lower mold, an exhaust mechanism is provided inside the upper mold, the upper end of the base and both sides of the lower mold are slidably connected to an inclined surface block, the inclined surface block is in contact with both the lower mold and the upper mold, the bottom of the inclined surface block is fixedly connected to a guide block, and the guide block is slidably connected to the base.

[0007] The principle of the present utility model is that when in use, the connecting seat is pushed downward by the hydraulic cylinder, and the connecting seat pushes the upper mold downward through the connecting frame to close the mold with the lower mold. After the upper mold and the lower mold are closed, the material can be injected between the two. At the same time as the material enters, the air in the upper mold and the lower mold is squeezed into the hollow cylinder, and then the plug is pushed open under the action of air pressure, and then discharged from the exhaust hole. When the air is discharged, the plug will be reset under the action of spring 2 to prevent air backflow. In addition, in the process of closing the upper mold and the lower mold, the pressure rod on the upper mold moves downward synchronously and squeezes the inclined surface block so that the inclined surface block approaches the direction of the upper mold and the lower mold, and fits against the sides of the two, so that the upper mold and the lower mold are aligned.

The telescopic shaft of the hydraulic cylinder 5 passes through the top seat 4 and is slidably connected to the top seat 4, and the end of the telescopic shaft is fixedly connected to the connecting seat 6, and the side of the connecting seat 6 is fixedly connected to a plurality of connecting frames 7, and the bottom of the connecting frame 7 is fixedly connected to the upper mold 8, and the upper mold 8 is fitted with the lower mold 2, and the upper end of the base 1 and both sides of the lower mold 2 are slidably connected with a ramp block 10, which contacts both the lower mold 2 and the upper mold 8, and the bottom of the ramp block 10 is fixedly connected to a guide block 11, which is slidably connected to the base 1.

[0023] like Figure 1 、 Figure 2 、 Figure 4 As shown, a guide rod 12 is fixedly connected to the inside of the base 1. The guide rod 12 passes through the guide block 11 and is slidably connected to the guide block 11. A spring 13 is sleeved on the outside of the rod body of the guide rod 12. The arrangement of the guide rod 12 and the guide block 11 has a guiding effect on the lateral movement of the base 1. One end of the spring 13 is fixedly connected to the guide block 11, and the other end of the spring 13 is fixedly connected to the inner surface of the base 1. Through the arrangement of the spring 13, the reaction force can be applied to the ramp block 10 through the guide block 11.

Through the arrangement of the pressure rod 14, a downward thrust can be applied to the ramp block 10, causing it to be forced to move laterally.

[0024] like Figure 2 、 Figure 3 As shown, the upper mold 8 is provided with a venting mechanism 9, which provides venting between the lower mold 2 and the upper mold 8. The venting mechanism 9 comprises a hollow cylinder 91 fixedly connected to the interior of the upper mold 8. A tapered tube 92 is fixedly connected to the interior of the hollow cylinder 91. A plurality of fixed rods 93 are fixedly connected to the interior of the tapered tube 92. A central block 94 is fixedly connected to the plurality of fixed rods 93.

The provision of the exhaust hole 99 facilitates exhaust from the hollow cylinder 91 .

[0025] The specific implementation process of the present invention is as follows: when in use, the hydraulic cylinder 5 pushes the connecting seat 6 downward, and the connecting seat 6 pushes the upper mold 8 down through the connecting frame 7, so that it is closed with the lower mold 2. After the upper mold 8 and the lower mold 2 are closed, the material can be injected between the two. At the same time as the material enters, the air in the upper mold 8 and the lower mold 2 is squeezed into the hollow cylinder 91, and then the plug 96 is pushed open under the action of air pressure, and then discharged from the exhaust hole 99.
