[0024] Please refer to Figures 1-7 A technical solution provided by the utility model:​

[0025] In this embodiment, an engine plastic part mold with positioning structure comprises a lower base 1, an upper base 2 is arranged above the lower base 1, four plug blocks 3 are arranged in the upper base 2 in a sliding manner, a slot 4 is arranged below the plug blocks 3, the plug blocks 3 can be inserted into the slot 4, and an extension rod 5 is fixedly arranged at the lower end of the slot 4.

[0026] In this embodiment, two extension rods 5 are symmetrically arranged along the center line of the slot 4, each two extension rods 5 form a group, and four groups of extension rods 5 are arranged, the extension rods 5 are hollow inside, a spring 6 is fixedly arranged at the lower end of the extension rods 5, and a top block 7 is fixedly arranged at the upper end of the extension rods 5.

[0027] In this embodiment, the top block 7 is in sliding connection with the slot 4, protruding blocks 8 are fixedly arranged at both ends of the top block 7, the protruding blocks 8 are in sliding connection with the lower base 1, movable plates 9 are arranged outside the protruding blocks 8, springs 10 are fixedly arranged at the other ends of the movable plates 9, the springs 10 are arranged in pairs, and the other ends of the springs 10 are fixedly connected with the lower base 1.

[0028] In this embodiment, clamping grooves 11 are arranged below the springs 10 on the outer surfaces of the movable plates 9, the protruding blocks 8 can be inserted into the clamping grooves 11, a hammer 12 is fixedly arranged at the upper end of the movable plate 9, the hammer 12 is in sliding connection with the lower base 1, and a connecting plate 13 is fixedly arranged between the extension rods 5 at the lower end of the top block 7.

[0029] In this embodiment, the connecting plate 13 is arranged in a cross shape, the connecting plate 13 is in sliding connection with the lower base 1, a top column 14 is fixedly arranged at the upper end of the connecting plate 13, the top column 14 is in sliding connection with the lower base 1, and a lower mold 18 is arranged in the middle of the lower base 1.

[0030] In this embodiment, the top column 14 is arranged in the middle of the lower mold 18, the top column 14 is arranged in five, an upper mold 17 is arranged above the lower mold 18, the upper mold 17 is fixedly connected with the upper base 2, a connecting plate 15 is arranged above the upper mold 17, the connecting plate 15 is fixedly connected with the plug blocks 3, and the connecting plate 15 is also arranged in a cross shape.

[0031] In this embodiment, the connecting plate 15 is in sliding connection with the upper base 2, a top column 16 is fixedly arranged at the lower end of the connecting plate 15, the number and position of the top column 16 are consistent with those of the top column 14, and the top column 16 is in sliding connection with the upper mold 17.

[0032] Working principle: when the upper base 2 is pressed down, the plug 3 will be inserted into the slot 4 first; if there is a position deviation between the two bases at this time, under the synergistic effect of the four plugs 3 and the slots 4, the two bases can be slightly displaced, so as to complete the closing; however, if the offset is too large, the base will not be closed; after the plug 3 enters the slot 4, it will be temporarily placed on the top block 7; with the continuous pressing of the upper base 2, the plug 3 will naturally press the top block 7 down; when the top block 7 is completely pressed down, the movable plates 9 on both sides will move to the middle under the elastic force of the second spring 10, at this time the protruding block 8 will enter the clamping groove 11; at the same time, the hammer 12 can also move to the middle and finally knock the plug 3, making a crisp sound; after each closing, once the knocking sound is heard, it means that the position of the base after closing is accurate, and the subsequent work can be carried out immediately.

[0033] When the plug 3 and the top block 7 move, they can drive the top column one 14 and the top column two 16 to move synchronously until their top parts are in the same plane as the surfaces of the upper mold 17 and the lower mold 18; when the base is opened after the injection molding process is completed, the top column one 14 will be pushed out upward with the resetting action of the top block 7; while the top column two 16 will be lowered with the natural falling of the plug 3; by skillfully setting the top column one 14 and the top column two 16, after the injection is completed, they can synergistically act to smoothly push out the molded plastic parts.

[0034] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
