[0001] The utility model relates to the field of mold equipment, in particular to a guide column assembly for precise guidance of a mold. Background Art

[0002] With the rapid development of the automotive industry, the precision requirements for auto parts are increasing. Molds, as key equipment in the auto parts manufacturing process, have a direct impact on product quality and production efficiency. Large automotive molds, in particular, are prone to deviation during the mold closing process due to their complex structure and large size. This can lead to reduced molding precision and even scrap.

[0003] In existing technology, mold guides typically use a combination of guide pins and guide sleeves. However, in practical applications, this traditional structure has many shortcomings: first, it is difficult to ensure machining accuracy and precisely control the clearances between components, which can easily cause the mold to shift during closing. Second, there is severe friction and wear between the guide pins and guide sleeves, which affects the guide accuracy and service life.

[0004] In response to the above problems, the market urgently needs a new type of guide pin assembly that can provide stable and precise guiding functions in large automotive molds, while reducing friction and wear, and improving the service life and production efficiency of the mold. Utility Model Content

[0005] In response to the problems existing in the background technology, the utility model provides a guide column assembly for precise guidance of the mold, which aims to solve the problem of deviation that is easy to occur in the closing process of large automobile molds, and improve the positioning accuracy and production efficiency of the mold. The device includes an upper guide column seat and a lower guide column seat, the upper guide column seat is a concave stepped shape, and the lower guide column seat is a convex stepped shape. The upper guide column seat and the lower guide column seat are engaged with each other up and down to form a complete rectangular parallelepiped.

[0006] Furthermore, a guide column is provided at the concave step of the upper guide column seat, a guide hole is provided at the convex step of the lower guide column seat, and a guide sleeve is provided inside the guide hole. When the upper guide column seat and the lower guide column seat are closed, the guide column can be inserted into the guide sleeve.

[0007] Preferably, the guide column head is tapered to facilitate insertion into the guide sleeve.

[0008] Furthermore, wear-resistant plates are respectively provided on both sides of the concave step of the upper guide column seat.

[0009] Preferably, the wear-resistant plate is made of alloy wear-resistant steel plate.

[0010] Furthermore, a limiting ring is provided at the tail end of the guide post, and the limiting ring is used to limit the engagement distance between the upper guide post seat and the lower guide post seat.

[0011] Furthermore, a vent hole is provided on the outer side of the lower guide post seat, and the vent hole is connected to the guide hole, so that the air can be quickly discharged when the guide post is inserted into the guide sleeve.

[0012] Furthermore, a plurality of keys are respectively provided above the upper guide column seat and below the lower guide column seat, and the keys are used for positioning between the upper guide column seat and the lower guide column seat and the upper and lower mold base plates.

[0013] Preferably, three of the keys are respectively provided above the upper guide column seat and below the lower guide column seat.

[0014] The advantages and beneficial effects of the present invention are as follows: the present invention realizes precise guidance of the upper and lower molds through the precise matching of the guide pin and the guide sleeve, greatly improving the positioning accuracy of the mold. During the installation and debugging of the mold, it can greatly reduce the adjustment time and workload, thereby improving production efficiency. The conical design of the guide pin head and the lubrication structure inside the guide sleeve make the guide pin smoother when inserted into the guide sleeve, reducing friction and wear, thereby extending the service life of the mold and reducing maintenance costs. The air vent provided on the outside of the lower guide pin seat is connected to the guide hole. When the guide pin is inserted into the guide sleeve, the air in the guide hole can be quickly discharged, reducing the influence of air pressure on the insertion of the guide pin and improving the stability of the guide.

[0019] 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, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0020] like Figure 1 、 Figure 2 Figure 1 shows a guide pin assembly for precise mold guidance. The assembly primarily comprises an upper guide pin seat 1 and a lower guide pin seat 2. The upper guide pin seat 1 is designed with a concave stepped shape, offering a clear stepped structure that facilitates mating with the lower guide pin seat 2. The lower guide pin seat 2, on the other hand, features a convex stepped shape that matches the upper guide pin seat 1, ensuring a tight engagement between the two. When the upper and lower guide pin seats 1 and 2 engage, they form a complete rectangular parallelepiped structure, providing stable support and guidance.

[0021] A guide post 3 is positioned on the concave step of the upper guide post seat 1. The head of the guide post 3 is tapered, allowing for smoother insertion into the guide sleeve 5. Correspondingly, a guide hole 4 is positioned on the convex step of the lower guide post seat 2, housing a guide sleeve 5. The design of the guide sleeve 5 ensures a precise fit with the guide post 3, achieving precise guidance.

[0022] In this embodiment, in order to further enhance the wear resistance and service life of the guide post assembly, wear-resistant plates 6 are installed on both sides of the concave step of the upper guide post seat 1. The wear-resistant plates 6 are made of alloy wear-resistant steel plates. The wear-resistant plates 6 prevent the upper and lower guide seats from wearing out due to long-term use.

[0023] A stop ring 7 is located at the end of the guide post 3. This ring limits the engagement distance between the upper guide post seat 1 and the lower guide post seat 2, preventing excessive compression during mold closing. The design of the stop ring 7 ensures stability and precision during mold closing.

[0024] The outer side of the lower guide post seat 2 is provided with a vent hole 8, which is connected to the guide hole 4. When the guide post 3 is inserted into the guide sleeve 5, the vent hole 8 can quickly discharge the air in the guide hole 4, thereby reducing the influence of air pressure on the insertion of the guide post and improving the stability of the guide.

[0025] To facilitate the positioning and installation of the guide post assembly with the upper and lower mold bases, multiple keys 9 are provided above the upper guide post seat 1 and below the lower guide post seat 2. The design of the keys 9 ensures accurate positioning of the guide post assembly during installation and commissioning. In this embodiment, three keys 9 are provided above the upper guide post seat 1 and below the lower guide post seat 2.

[0026] Specific steps:

[0027] During mold operation, the upper mold begins to descend, and the upper guide post holder 1 mounted on the upper mold also descends. As the upper mold continues to descend, the guide post 3 accurately inserts into the guide sleeve 5 mounted on the lower guide post holder 2 of the lower mold, providing initial rough guidance. Subsequently, the upper mold continues to descend, and the wear-resistant plate 6 mounted on the upper mold contacts the flat surface of the lower mold, further ensuring precise guidance of the upper and lower molds. In this way, the present invention effectively solves the problem of misalignment that can easily occur during the closing process of large automotive molds, significantly improving mold positioning accuracy and production efficiency.

[0028] The above describes in detail the guide pin assembly for precise mold guidance provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
