[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides an embodiment of a plastic injection mold with a correction function.

[0024] A plastic injection mold with a correction function includes a support platform 1, a lower mold 2 is installed inside the support platform 1, an upper mold 4 installed above the lower mold 2 through a hydraulic lifting frame 3, a correction mechanism 5 is provided on the support platform 1, and the correction mechanism 5 includes a fixed frame 6 fixedly installed on the bottom of the support platform 1, a bidirectional screw rod 7 is movably installed inside the fixed frame 6, a turntable 8 is fixedly installed at both ends of the bidirectional screw rod 7, a moving block 9 connected by a thread is provided on the bidirectional screw rod 7, a support frame 10 is fixedly installed on the moving block 9, and a correction plate 11 is fixedly installed on one end of the support frame 10. By setting the correction mechanism 5, the correction can be performed during the replacement and installation of the lower mold 2 and the upper mold 4. When installing and replacing the lower mold 2 and the upper mold 4, first place the lower mold 2 on the support table 1, and then rotate the turntable 8 to drive the bidirectional screw 7 to rotate. The rotation of the bidirectional screw 7 drives the support frame 10 to move through the moving block 9, so that the support frame 10 pushes the correction plate 11, so that the two correction plates 11 push the lower mold 2 to fit and position the lower mold 2 at the center of the support table 1, and then place the upper mold 4 on the lower mold 2, and rotate the turntable 8 again through a series of transmissions to make the correction plate 11 fit on the lower mold 2 and the upper mold 4, so that the upper mold 4 is accurately fitted with the lower mold 2, and finally start the hydraulic lifting frame 3 to descend and contact the upper mold 4 to install and fix it. After the correction, deviations can be avoided during the installation process, and inaccurate mold closing can be prevented during the production and processing process.

[0025] In this embodiment, Figure 1-Figure 4As shown, two push rods 12 are symmetrically fixedly mounted on the surface of the turntable 8. The surface of the push rods 12 is provided with anti-slip grooves. A fixed block 13 is fixedly mounted on both sides of the support platform 1. An electric telescopic rod 14 is fixedly mounted on the fixed block 13. A magnetic block 15 is fixedly mounted on the output end of the electric telescopic rod 14. A magnetic ring 16 is fixedly mounted on the turntable 8. The magnetic block 15 and the magnetic ring 16 are mutually attracted. The arrangement of the push rods 12 and the protective grooves on the surface of the push rods 12 make it easier to push the turntable 8 to rotate. Through the arrangement of the fixed block 13, the electric telescopic rod 14, the magnetic block 15 and the magnetic ring 16, after the correction plate 11 is attached to the lower mold 2 and the upper mold 4 for correction, the electric telescopic rod 14 is activated to drive the magnetic block 15 to descend and mate with the magnetic ring 16. Under the attraction of the magnetic block 15 and the magnetic ring 16, the turntable 8 can be fixed, thereby limiting the bidirectional screw rod 7, preventing the bidirectional screw rod 7 from rotating due to other factors and causing the correction plate 11 to loosen.

[0026] In this embodiment, Figure 1-Figure 4 As shown, the bottom of the lower mold 2 is provided with a condensation plate 17 fixedly mounted on the support platform 1, and a wire 18 extending to the outside of the support platform 1 is fixedly mounted on the condensation plate 17. A plurality of movable wheels 19 are fixedly mounted on the surface of the support platform 1. A fixed plate 20 is fixedly mounted on both sides of the bottom of the support platform 1. A screw 21 is movably mounted on the fixed plate 20, and a support plate 22 is mounted at the bottom of the screw 21. Through the arrangement of the condensation plate 17 and the wire 18, after the injection molding process is completed, the wire 18 can be connected to an external power supply to start the condensation plate 17 to cool the lower mold 2, thereby cooling the plastic device in the lower mold 2. The arrangement of the movable wheels 19 facilitates the movement of the support platform 1 as a whole. Through the arrangement of the fixed plate 20, the screw 21 and the support plate 22, after the movement is completed, the screw 21 is rotated to drive the support plate 22 to descend and contact the ground. After the support plate 22 contacts the ground, it can cooperate with the fixed plate 20 to support the support platform 1 as a whole, preventing it from moving during production and processing.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a plastic injection mold with a correction function provided by this embodiment is as follows:

[0028] When installing and replacing the lower mold 2 and the upper mold 4, first place the lower mold 2 on the support table 1, then rotate the turntable 8 to drive the bidirectional screw 7 to rotate, and the rotation of the bidirectional screw 7 drives the support frame 10 to move through the moving block 9, so that the support frame 10 pushes the correction plate 11, and the two correction plates 11 push the lower mold 2 to fit, and correct the lower mold 2 to position it at the center of the support table 1, and then place the upper mold 4 on the lower mold 2, and rotate the turntable 8 again through a series of transmissions to make the correction plate 11 fit on the lower mold 2 and the upper mold 4, so that the upper mold 4 is accurately fitted with the lower mold 2, and finally start the hydraulic lifting frame 3 to descend to contact the upper mold 4 and install and fix it. After correction, deviation can be avoided during the installation process.

[0029] In summary, in this embodiment, according to a plastic injection mold with a correction function of this embodiment, by setting the push rod 12 and setting a protective pattern on the surface of the push rod 12, the turntable 8 can be pushed to rotate more conveniently, and by setting the fixed block 13, the electric telescopic rod 14, the magnetic block 15 and the magnetic ring 16, after the correction plate 11 is used to fit on the lower mold 2 and the upper mold 4 for correction, the electric telescopic rod 14 is started to drive the magnetic block 15 to descend and fit with the magnetic ring 16. Under the adsorption of the magnetic block 15 and the magnetic ring 16, the turntable 8 can be fixed, and then the bidirectional screw rod 7 is limited to prevent the bidirectional screw rod 7 from being affected by other factors. The rotation affects the loosening of the correction plate 11. Through the setting of the condensation plate 17 and the wire 18, after the injection molding process is completed, the wire 18 is connected to an external power supply to start the condensation plate 17 to cool the lower mold 2, so as to cool the plastic devices in the lower mold 2. Through the setting of the moving wheel 19, the overall movement of the support platform 1 is facilitated. Through the setting of the fixed plate 20, the screw 21 and the support plate 22, after the movement is completed, the screw 21 is rotated to drive the support plate 22 to descend and contact the ground. After the support plate 22 contacts the ground, it cooperates with the fixed plate 20 to support the support platform 1 as a whole, thereby avoiding movement during production and processing.
