DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figure 1 , Figure 2 As shown, a rotor injection mold provided by an embodiment of the utility model comprises a base 1 and a lower mold base 2 mounted on the top of the base 1, an upper mold base 3 is connected to the top of the lower mold base 2, and mounting blocks 12 are fixedly connected to the four corners of the base 1, and mounting holes are opened on the mounting blocks 12. The internal structures of the lower mold base 2 and the upper mold base 3 are both prior art.

[0023] like Figures 2 to 4 As shown, a mounting groove 101 is provided on the top surface of the base 1, a positioning column 4 is fixedly connected to the bottom surface of the mounting groove 101, and two groups of positioning strips 5 are symmetrically fixedly connected to the two side surfaces. The positioning column 4 is a trapezoidal column which is larger at the top and smaller at the bottom, and its length is the same as the length of the positioning strip 5. The right end surfaces of the positioning column 4 and the positioning strip 5 are flush, and the distance between the right end surfaces of the positioning column 4 and the mounting groove 101 is greater than the length of the lower mold base 2. A positioning groove 1 201 which is compatible with the positioning column 4 is provided on the bottom surface of the lower mold base 2, and a positioning groove 2 202 which is compatible with the positioning strip 5 is provided on the side surface. The length of the positioning column 4 is half of the length of the lower mold base 2, and when the left end surface of the lower mold base 2 abuts against the left end surface of the mounting groove 101, the midpoints of the positioning column 4, the positioning strip 5 and the lower mold base 2 are located on the same vertical plane.

[0024] The cooperation of the positioning column 4 and the positioning bar 5 can effectively prevent the lower mold base 2 from shaking inside the installation groove 101, and effectively improve the stability of the installation of the lower mold base 2. Since the distance between the right end face of the positioning column 4 and the positioning bar 5 and the right end face of the installation groove 101 is greater than the length of the lower mold base 2, when the right end face of the lower mold base 2 abuts against the right end face of the installation groove 101, the positioning column 4 and the positioning bar 5 are respectively separated from the positioning groove 1 201 and the positioning groove 2 202, which is convenient for taking and placing the lower mold base 2.

[0025] like Figure 3 and Figure 5As shown, a slide groove 102 is provided on the side of the mounting groove 101 between each group of positioning strips 5, and a screw rod 6 and a slide rod 7 are respectively installed inside the two slide grooves 102. The slide rod 7 is fixedly installed inside one slide groove 102, and the screw rod 6 is rotatably installed inside the other slide groove 102, and a handwheel 13 is installed after one end thereof passes through the side wall of the base 1, and a push plate 8 is provided between the screw rod 6 and the slide rod 7. A storage groove adapted to the push plate 8 is provided on the right end surface of the mounting groove 101 inside the base 1, and ear plates 9 that are sleeved on the outside of the screw rod 6 and the slide rod 7 are symmetrically fixed at both ends of the push plate 8, and nuts 10 and sleeves 11 are respectively fixed on the two ear plates 9, the nut 10 is threadedly connected to the screw rod 6, and the sleeve 11 is slidably sleeved on the outside of the slide rod 7.

[0026] By rotating the screw rod 6 through the hand wheel 13, the screw rod 6 and the nut 10 rotate relative to each other, causing the nut 10 to drive the push plate 8 to move through the ear plate 9, thereby pushing the lower die base 2 and cooperating with the left end face of the installation groove 101 to clamp and fix the lower die base 2.

[0027] In specific use, the lower die base 2 is placed at the right end of the installation groove 101, and the hand wheel 13 is rotated to prompt the push plate 8 to push the lower die base 2 to slide to the left, so that the positioning groove 1 201 can be wrapped around the outside of the positioning column 4, and the positioning groove 2 202 can be wrapped around the outside of the positioning bar 5. The stability of the installation of the lower die base 2 is improved by the cooperation of the positioning column 4 and the positioning bar 5. When the left end face of the lower die base 2 abuts against the left end face of the installation groove 101, the hand wheel 13 is continued to be rotated, and the lower die base 2 is clamped and fixed by the push plate 8, thereby further improving the stability of the installation of the lower die base 2.

[0028] When replacing the mold, the hand wheel 13 is rotated in the opposite direction to move the push plate 8 to the inside of the storage groove, and the lower mold base 2 is pushed to the right end of the installation groove 101. At this time, the lower mold base 2 can be removed and replaced.

[0029] The installation and disassembly process of the mold does not require the removal of bolts, which saves time and effort and is simpler than traditional mold installation.

[0030] The undisclosed parts in the present invention are all prior art, and their specific structures and working principles are not described in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
