Description
Technical Field
[0001] The utility model relates to the technical field of mold guiding, in particular to a 45-degree square guide column used for mold guiding. Background Art
[0002] Molds are various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. They are tools used to produce shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the shape of the object by changing the physical state of the molded material.
[0003] Conventional molds typically place round or square guide pins in open areas for mold guidance. However, some molds lack sufficient space for guide pins due to mold structure limitations. To accommodate these pins, the mold may need to be enlarged, which increases mold costs and can even make the enlarged mold unsuitable for production on the planned production machine, forcing production on a larger machine than planned, further increasing product manufacturing costs.
[0004] To this end, we propose a 45° square guide column for mold guiding to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art. The utility model proposes a 45° square guide column for mold guidance which does not require enlarging the mold and reduces the mold cost.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a 45° square guide column for mold guiding, comprising: a guide column and at least two square guide sleeves, the guide column is a column structure with a square cross-section, and a 45-degree opening angle is set on an edge in the corresponding height direction to form a vertical and smooth outer edge surface, a first positioning hole corresponding to the side edge of the external mold is provided on the outer edge surface, and the two connected surfaces away from the outer edge surface in the height direction of the guide column are mating surfaces, each of the mating surfaces is fixed with a first pin key at the same position on the top, and is fixed to each of the square guide sleeves at the same position on the bottom, and a second pin key is also fixed to the center of the back of each square guide sleeve, and the first pin key and the second pin key are respectively embedded in the external mold side edge.
[0007] Furthermore, the top surface of the guide pillar is connected to the top surface of the external mold to form a plane, and the bottom surface thereof is suspended.
[0008] Furthermore, a second positioning hole is opened at the center of the first pin key and is fixed to the guide column screw at the second positioning hole; a third positioning hole is opened at the center of the second pin key and is fixed to the guide column screw at the third positioning hole.
[0009] Furthermore, the first positioning holes include two and are equidistantly arranged axially at the height of the guide column. The first positioning holes pass through the guide column and are fixed with screws along the edge of the external mold.
[0010] Furthermore, the height position of the first pin key is located at the center of the interval between the height positions of the two first positioning holes.
[0011] Furthermore, the square guide sleeves include two, each of which is provided with an oil groove on the surface in contact with the guide column. Each of the square guide sleeves includes two oil grooves, which are triangular structures and are symmetrical about the center of the third positioning hole. Each of the slide grooves is connected to the third positioning hole.
[0012] Furthermore, one guide post and two square guide sleeves are matched to form a group, which includes multiple groups and are distributed along the side edge of the external mold. The external mold opens a right-angle opening on its side edge to contact the matching surface of each group of guide posts.
[0013] Compared with the existing technology, the beneficial effects of the utility model include: the guide column set at a 45° opening angle can fit the right-angled opening along the edge of the corresponding external mold. The fitting process relies on the first pin key on the guide column and the second pin key on the square guide sleeve for internal locking, and is supplemented by the corresponding positioning hole screw for positioning. At the same time, an oil groove is added inside the square guide sleeve to ensure smooth contact between the guide column and the mating surface of the square guide sleeve. The overall structure is compact and practical, which reduces the space requirement for the mold itself and greatly reduces the cost requirement for the guide column guidance.

[0021] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.
[0022] According to one embodiment of the present invention, Figure 1-Figure 5 Shown.
[0023] In this embodiment, as for the overall structure, a 45° square guide column for mold guiding includes: a guide column 1 and at least two square guide sleeves 2, the guide column 1 is a column structure with a square cross-section, and a 45-degree opening angle is set at one edge in the corresponding height direction to form a vertical and smooth outer edge surface 3, and a first positioning hole 4 corresponding to the side edge of the external mold is provided on the outer edge surface 3, and the two connected surfaces of the guide column 1 away from the outer edge surface 3 in the height direction are mating surfaces 5, and each of the mating surfaces 5 is fixed with a first pin key 6 at the same position on the top, and is fixed to each of the square guide sleeves 2 at the same position on the bottom, and a second pin key 7 is also fixed to the back center of each of the square guide sleeves 2, and the first pin key 6 and the second pin key 7 are respectively embedded in the external mold side edges.
[0024] In this embodiment, if Figure 1 As shown, the top surface of the guide post 1 is connected to the top surface of the external mold to form a plane, and its bottom surface is suspended. Furthermore, the first pin key 6 has a second positioning hole 8 at its center and is screwed to the guide post 1 at the second positioning hole 8. The second pin key 7 has a third positioning hole 9 at its center and is screwed to the guide post 1 at the third positioning hole 9.
[0025] like Figure 2-Figure 4 As shown, the first positioning holes 4 include two and are equidistantly arranged at the height of the guide post 1. The first positioning holes 4 pass through the guide post 1 and are fixed with screws along the edge of the external mold. The height position of the first pin key 6 is located at the center of the height position interval between the two first positioning holes 4.
[0026] like Figure 5As shown, the square guide sleeves 2 include two, each having an oil groove 10 on the surface in contact with the guide post 1. Each square guide sleeve 2 includes two oil grooves 10, which are triangular in structure and symmetrically centered about the third positioning hole 9. Each slide groove is connected to the third positioning hole 9. One guide post 1 and two square guide sleeves 2 form a set, which can be multiple sets and distributed along the side edge of the external mold. The external mold has right-angled openings on its side edge to contact the mating surface 5 of each set of guide posts 1.
[0027] Through the above structure, for the vertical guidance of the external mold, multiple groups of the above structures can be distributed around the circumference for positioning and guiding. Each group of the above structures consists of a guide column 1 and two square guide sleeves 2. The outer edge 3 of the external mold is formed by gluing at 45 degrees on an edge in the height direction of the guide column 1.
