[0014] Mark explanation:

[0015] 1 upper die body, 2 lower die body, 3 anti-deviation guide column, 31 base, 32 right angle column, 33 stand, 34 right angle guide slot, 35 rubber pad, 4 ear plate, 5 cylinder, 6 triangular rib guide column, 7 triangular base. Specific implementation

[0016] The utility model will be further described below in combination with the drawings.

[0017] In order to make the utility model purposes, technical scheme and advantages more clearly, the following is in combination with the drawings and specific implementation, the utility model is further detailed.The specific implementation described here is only used to explain the utility model, and is not used to limit the utility model.

[0018] Reference Figs. 1-3 An anti-deviation die-casting die, including upper die body 1 and lower die body 2, the four corners of upper die body 1 are provided with anti-deviation guide column 3 respectively, anti-deviation guide column 3 includes base 31, the upper surface of base 31 is provided with right angle column 32 and stand 33 respectively, and the right angle guide slot 34 between the two, base 31 is fixed on lower die body 2, the included angle of right angle column 32 is located at the four corners of upper die body 1, and stand 33 penetrates upper die body 1, and ear plate 4 is arranged on the left and right sides of upper die body 1, and cylinder 5 is arranged between ear plate 4 and lower die body 2.Specifically, anti-deviation guide column 3 is used for limiting upper die body 1, through the cooperation of right angle column 32 and stand 33, double limiting of upper die body 1 is carried out, to avoid the deviation of upper die body 1;Anti-deviation guide column 3 is integrally formed, not easy to deform, can effectively limit upper die body 1, provide guide, make upper die body 1 move stably up and down, prevent upper die body 1 from deviating after long time operation, improve product yield.

[0019] In the embodiment, the bottom of right angle guide slot 34 is provided with rubber pad 35.Rubber pad 35 is used to reduce the noise when upper die body 1 drops on the one hand, and can avoid damage caused by upper die body 1 on the other hand.

[0020] In the embodiment, the outside of ear plate 4 is provided with triangular groove, triangular rib guide column 6 is longitudinally arranged in triangular groove, triangular base 7 is arranged at the lower part of triangular rib guide column 6, and triangular base 7 supports triangular rib guide column 6;Triangular rib guide column 6 utilizes the stable characteristics of triangle, not easy to deform, so that deviation can be avoided.

[0021] In this embodiment, the upper mold body 1 and the ear plate 4 are integrally formed, which improves the service life and makes them less prone to deformation and displacement.

[0022] In this embodiment, ball bearings (not shown in the figure) are arranged longitudinally in the left and right inner walls of the right-angle guide groove 34. The ball bearings can reduce the friction of the upper mold body 1 moving up and down and reduce noise; the ball bearings are embedded in the right-angle pillars 32 and 33, with only a small part of the surface exposed.

[0023] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
