Description

Technical Field

[0001] This utility model relates to the field of guide post technology, and in particular to a novel guide post for precision molds. Background Technology

[0002] Guide pillars are guiding elements used in molds in conjunction with components to ensure precise positioning and guide the mold's movement. They are generally shouldered cylinders and usually have oil grooves. Ball bearing guide pillar assemblies are devices used on molds to allow the moving mold platen to smoothly complete the mold opening action under the action of the ejector mechanism. Guide pillar and guide sleeve assemblies are guiding elements used to guide the mold's stroke and ensure its precision. In existing technology, ball bearing guide pillar assemblies are mainly used as guiding elements in molds. Their ball bearing cages contain balls, offering advantages such as high precision and low operating costs.

[0003] Currently, conventional guide pillars require manual lubrication multiple times during use to prevent wear of the ball bearings over a long period. However, repeated manual lubrication wastes time and affects production efficiency. In addition, after prolonged use, the guide pillars may experience a decrease in resilience, which can cause them to become ineffective.

[0004] Therefore, those skilled in the art have provided a novel guide post for precision molds to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel guide post for precision molds. Through the addition of a springback mechanism, the guide post can have excellent rebound performance, thereby improving its service life. Furthermore, through the addition of a lubrication mechanism, the guide post can automatically lubricate the balls during use, eliminating the need for multiple manual lubrications and improving production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel guide pillar for precision molds includes an upper fixing plate, a lower fixing plate, and a guide pillar body. The upper end of the lower fixing plate is provided with a spring-back mechanism, and the guide pillar body is provided with a lubrication mechanism.

[0008] The rebound mechanism includes a fixed base, a guide post body is provided at the upper end of the fixed base, damping rods are provided on both sides inside the fixed base, a first spring is sleeved on the outer wall of the damping rod, a fixed rod is connected to one end of the first spring, a triangular pressure plate is slidably connected to the upper end of the fixed rod, a pressure plate is provided at the upper end of the triangular pressure plate, and a limit groove is provided inside the guide post body at a position corresponding to the pressure plate, and the limit groove and the pressure plate cooperate with each other;

[0009] Through the above technical solution, the designed rebound mechanism enables the guide post to have excellent rebound performance, thereby improving the service life of the guide post.

[0010] Furthermore, the lubrication mechanism includes an oil reservoir with multiple first oil outlet holes at the bottom of the reservoir. Arc-shaped blocks are provided on both sides of the upper end of the inner wall of the guide column body. Multiple second springs are provided on the outer wall of one end of each arc-shaped block, and multiple second oil outlet holes are provided on the outer wall of each arc-shaped block. Multiple third oil outlet holes are provided inside the guide column body, and the third oil outlet holes correspond to the first oil outlet holes. An oil-absorbing sponge is provided in the middle of the outer wall of the guide column body, with the upper end of the oil-absorbing sponge corresponding to the third oil outlet holes. An oil filling hole is provided on one side of the upper surface of the oil reservoir.

[0011] The above technical solution, through the lubrication mechanism, allows the guide column to automatically lubricate the balls during use, eliminating the need for multiple manual lubrications and improving production efficiency.

[0012] Furthermore, a limit sleeve is provided at the bottom end of the upper fixing plate, and a pressure rod is provided inside the limit sleeve;

[0013] The above technical solution enables the guide post to be used normally.

[0014] Furthermore, a sliding sleeve is provided at the upper end of the outer wall of the guide post body, and a plurality of balls are provided through the outer wall of the sliding sleeve;

[0015] The above technical solutions reduce mold displacement and improve the accuracy of guide pillar movement.

[0016] Furthermore, a limit ring is provided at the upper end of the guide post body;

[0017] The above technical solution prevents the sliding sleeve from detaching from the guide post body.

[0018] Furthermore, a third spring is provided at the lower end of the outer wall of the guide post body;

[0019] The above technical solutions increase the support of the guide pillars and reduce vibration.

[0020] Furthermore, a limit post is provided between the two fixed rods;

[0021] The above technical solution enables the fixed rod to move horizontally.

[0022] Furthermore, threaded through holes are provided at both ends of the upper fixing plate and the lower fixing plate;

[0023] The above technical solution facilitates the use of bolts for fixing.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a novel guide post for precision molds. When the guide post moves upward, the first spring resets, causing the fixed rod to move, thereby causing the triangular pressure plate to be squeezed out, driving the pressure plate to move upward, and pushing the pressure rod to move upward, which improves the rebound performance of the guide post. Through the set rebound mechanism, the guide post can have good rebound performance, thereby improving the service life of the guide post.

[0026] 2. This utility model proposes a novel guide post for precision molds. When the pressure rod moves downward, the arc-shaped locking block is squeezed inward, thereby connecting the second, first, and third oil outlet holes on the arc-shaped locking block. This allows the lubricating oil inside the oil reservoir to enter the oil-absorbing sponge. When the sliding sleeve moves to the lower end, the ball bearings come into contact with the oil-absorbing sponge, thus coating the outer surface of the ball bearings with oil and preventing wear of the ball bearings due to prolonged use. Through the designed lubrication mechanism, the guide post can automatically lubricate the ball bearings during use, eliminating the need for multiple manual lubrications and improving production efficiency.
