[0028] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides an injection mold for automotive aluminum alloy castings, which includes an operation panel 1, a static mold 2 is fixedly installed on the top of the operation panel 1, two horizontal plates 3 are installed on the outer wall of the static mold 2, and a built-in groove 4 is provided on the top of the static mold 2, a forward and reverse motor 5 is fixedly installed on the top of one of the horizontal plates 3, a threaded rod 6 is fixedly installed on one side of the outer wall of the forward and reverse motor 5, and an extrusion block 7 is threadedly connected to the outer wall of the threaded rod 6, a limiting column 8 is fixedly installed on the top of the other horizontal plate 3, and two first exhaust holes 9 are provided on the outer wall of the extrusion block 7, two second exhaust holes 10 are provided on one side of the inner wall of the static mold 2, and two third exhaust holes 11 are provided on one side of the outer wall of the static mold 2.

[0029] The working principle here is: start the forward and reverse motor 5, and drive the threaded rod 6 to rotate through the forward and reverse motor 5. Since the threaded rod 6 rotates inside the limit column 8 at the end away from the forward and reverse motor 5, the extrusion block 7 moves back and forth on the threaded rod 6, and two first exhaust holes 9 are opened on the extrusion block 7. When the automobile door handle mold is being manufactured, residual air will be generated at the internal mold core 16 due to extrusion. When the two first exhaust holes 9 on the extrusion block 7 correspond to the two second exhaust holes 10 and the two third exhaust holes 11 on the mold, since the two air outlet pipes 12 are inserted in the two third exhaust holes 11, the vacuum pump 13 is started to extract the residual air in the inner cavity of the mold, and the pressure relief of the inner cavity is adjusted, thereby ensuring the casting quality of the automobile door wrench mold and improving the qualified rate of the automobile door handle cast by the mold.

[0030] like Figure 1-Figure 5 As shown, the inner walls of the two third exhaust holes 11 are fixedly inserted with an exhaust pipe 12, a vacuum pump 13 is placed on the top of the operating panel 1, a strip groove 14 is opened at the bottom of the inner wall of the built-in groove 4, a strip slider 15 is movably embedded in the inner wall of the strip groove 14, and the top of the strip slider 15 is fixedly connected to the bottom of the extrusion block 7, a mold core 16 is set on the top of the static mold 2, and a thermal pressure sensor 17 is fixedly installed on one side of the outer wall of the static mold 2.

[0031] The working principle here is: through the action of two vacuum pumps 13, the remaining air in the inner cavity of the mold is effectively removed, and the strip slider 15 installed at the bottom of the extrusion block 7 is movably embedded in the strip groove 14, which improves the stability of the extrusion block 7 moving back and forth on the threaded rod 6, thereby improving the accuracy of the correspondence between the two first exhaust holes 9 on the extrusion block 7 and the two second exhaust holes 10 and the two third exhaust holes 11, thereby improving the use effect of the automobile door handle mold casting.

[0032] like Figure 1-Figure 5As shown, two insertion holes 18 are provided on the top of the static mold 2, and the inner walls of the two insertion holes 18 are movably inserted with insertion blocks 19, a baffle 20 is fixedly installed between the tops of the two insertion blocks 19, and a handle 21 is fixedly installed on one side of the outer wall of the baffle 20, a bracket 22 is fixedly installed on the top of the operating panel 1, and two cylinders 23 are fixedly installed on the bottom of the inner wall of the bracket 22, two limit rods 24 are fixedly installed on the tops of the two cross plates 3, and the tops of the two limit rods 24 are fixedly connected to the bottom of the inner wall of the bracket 22, and a movable mold 25 is movably sleeved between the outer walls of the four limit rods 24.

[0033] The working principle here is: use the handle 21 to insert the baffle 20 with two plug blocks 19 into the two plug holes 18, then the baffle 20 just closes the built-in groove 4, effectively preventing foreign matter from falling into the interior and affecting the flexibility of the extrusion block 7 to move back and forth, and convenient for the staff to inspect and repair the internal mechanism, start the two cylinders 23, and under the action of the four limit rods 24, the stability of the downward movement of the movable mold 25 is improved, preventing the movable mold 25 from directly contacting the static mold 2 and causing damage, and further improving the use effect of the mold casting.

[0034] Working principle: Start the forward and reverse motor 5, and drive the threaded rod 6 to rotate through the forward and reverse motor 5. Since the threaded rod 6 rotates inside the limiting column 8 at the end away from the forward and reverse motor 5, and the strip slider 15 installed at the bottom of the extrusion block 7 is movably embedded in the strip groove 14, the stability of the extrusion block 7 moving back and forth on the threaded rod 6 is improved, and two first exhaust holes 9 are opened on the extrusion block 7, and then the two cylinders 23 are started. Under the action of the four limiting rods 24, the stability of the downward movement of the movable mold 25 is improved, and the movable mold 25 is prevented from directly contacting the static mold 2 and causing damage. When the automobile door handle mold is being manufactured, incomplete air will be generated at the internal mold core 16 due to extrusion. When the two first exhaust holes 9 on the extrusion block 7 are in contact with the mold When the two second exhaust holes 10 and the two third exhaust holes 11 on the mold correspond to each other, since the two exhaust pipes 12 are inserted in the two third exhaust holes 11, the vacuum pump 13 is started to extract the remaining air in the inner cavity of the mold, and the pressure relief of the inner cavity is adjusted to ensure the casting quality of the automobile door wrench mold and improve the qualified rate of the automobile door handle cast by the mold. Secondly, the baffle 20 with two plug blocks 19 is inserted into the inside of the two plug holes 18 through the handle 21, and the baffle 20 just closes the built-in groove 4, effectively preventing foreign matter from falling into the inside and affecting the flexibility of the extrusion block 7 to move back and forth and adjust, and it is convenient for the staff to inspect and repair the internal mechanism. In general, the use effect of the adjustable automobile door handle mold casting structure is improved.
