Description

Technical Field

[0001] This utility model relates to the field of mold guide pillar technology, specifically a square guide pillar structure for a mold. Background Technology

[0002] Square guide pillars (commonly referred to as guide pillars or guide rods in molds) are guiding elements used in molds, mainly mounted on the mold base plate, playing a crucial role in positioning and guiding. They are generally shouldered cylinders with oil grooves, typically made of materials such as bearing steel, hot work die steel, and free-cutting iron, possessing high precision and excellent durability. During mold opening and closing, square guide pillars ensure accurate alignment of the upper and lower molds and guide them to move along a predetermined trajectory, thereby maintaining the stability and precision of the mold. However, existing square guide pillars are mainly installed through sliding connections using grooves and sliders. This results in greater sliding friction, potentially leading to more wear and energy loss, and may also cause vibration or instability during movement.

[0003] Therefore, we propose a square guide pillar structure for the mold. Utility Model Content

[0004] The purpose of this utility model is to provide a square guide pillar structure for a mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a square guide pillar structure for a mold, comprising:

[0006] The guide post body has a first threaded groove at the center of its bottom surface.

[0007] A locking mechanism is provided, wherein the bottom surface of the guide post body is equipped with a locking mechanism, the locking mechanism includes a cover plate, the cover plate is equipped with a cover plate, and an installation groove is provided in the center of the cover plate.

[0008] A connecting mechanism is provided, wherein the outer surface of the guide post body is equipped with a connecting mechanism, the connecting mechanism includes a bushing, the bushing is installed on the outer surface of the guide post body, and rollers are symmetrically and equidistantly mounted inside the bushing.

[0009] Preferably, the locking mechanism further includes a first bolt, which is installed inside the mounting groove and connected to the first threaded groove by threaded engagement. A bolt head is fixedly connected to the bottom surface of the first bolt, and a retaining groove is formed at the center of the bottom surface of the bolt head. The first bolt is connected to the cover plate through the mounting groove, and then the first bolt is engaged with the first threaded groove. The retaining groove in the bolt head allows for faster assembly using tools until the bottom end of the guide post body contacts the cover plate.

[0010] Preferably, a spring is installed on the outer surface of the guide post body.

[0011] Preferably, the connecting mechanism further includes a first moving groove. The guide post body has a first moving groove on its outer surface at the roller. A guide sleeve is installed on the outer surface of the bushing. The guide sleeve has a second moving groove on its inner wall surface at the roller. The guide post body moves parallel to the guide sleeve through the cooperation of the bushing and the roller. The inside of the bushing contacts the outer surface of the guide post body, and then the inside of the guide sleeve contacts the outer surface of the bushing. At this time, the guide sleeve can move within the first and second moving grooves through the cooperation of the roller inside the bushing, thus achieving connection with the guide post body. Compared with the sliding block connection, the roller rolling connection is relatively simple to maintain; only the worn roller needs to be replaced, without the need for major overhaul of the entire connecting component. This results in less damage to the guide post body and extends its service life.

[0012] Preferably, a second bolt is installed on the top surface of the guide post body, and an anti-detachment cap is fixedly connected to the top surface of the second bolt. A second threaded groove is formed inside the top of the guide post body at the location of the second bolt, and the anti-detachment cap is engaged with the guide post body through the cooperation of the second bolt and the second threaded groove. The connection is achieved through the cooperation of the second bolt and the second threaded groove at the bottom end of the anti-detachment cap.

[0013] Preferably, the outer surface of the guide sleeve is symmetrically provided with heat dissipation grooves, and the outer surface of the guide sleeve is provided with oil injection holes at equal intervals. During use, lubricating oil can be added to the roller through the oil injection holes. Combined with the heat dissipation grooves, this not only extends the service life but also provides additional heat dissipation.

[0014] Preferably, the guide post body is square, and the bushing and the interior of the guide sleeve are the same shape as the guide post body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the square guide post can be quickly assembled and spliced ​​by the cooperation of the first threaded groove, cover plate, mounting groove, first bolt, bolt head and slot, making the assembly of the square guide post more convenient. By using the cooperation of bushing, roller, first moving groove, guide sleeve and second moving groove, the roller rolling connection method is adopted. The relative movement between the connecting parts is realized by the rolling of the wheel. The rolling friction is relatively small, which is easier to reduce wear and energy loss than sliding friction. Due to the small rolling friction, it can usually provide more stable and precise movement. Attached Figure Description
