Description

Technical Field

[0001] The utility model relates to the field of squeeze casting machines, and particularly relates to a rolling sliding foot device for a horizontal squeeze casting machine. Background Art

[0002] The horizontal squeeze casting machine has become an important device in modern industrial production with its unique horizontal structure. It has a high degree of automation, is easy to operate, and can efficiently produce various metal castings, such as aluminum alloy, magnesium alloy, etc., and is widely used in fields such as automobiles, aviation, electronics, and mechanical manufacturing. In the squeeze casting process, the moving die and the stationary die need to cooperate with each other to form a casting cavity. However, since the moving die is prone to shaking during movement, the relative position between the moving die and the stationary die is shifted, ultimately resulting in uneven accuracy and quality of the casting products. Therefore, during the continuous squeeze casting process, a moving die sliding foot mechanism is required to adjust the position of the moving die in a timely manner to align the moving die and the stationary die to ensure product quality. Currently, sliding friction type sliding feet are mostly used for the moving template of horizontal squeeze casting machines. Due to the large sliding friction resistance of the friction type sliding feet, a large pressure is required for the clamping cylinder to push the moving template to move horizontally on the machine frame guide rail surface, resulting in an increase in energy consumption. In particular, when the lubrication is poor, the resistance of the sliding friction type sliding feet rises sharply, and at the same time, a harsh friction sound is emitted.

[0003] A sliding foot device for adjusting the relative position of a clamping moving template proposed in Patent CN220095433U includes sliding feet provided corresponding to the bottom of the clamping moving template, a locking mechanism installed on the side of the sliding feet facing the clamping moving template, a lifting mechanism installed on the sliding feet and having one end pressing against a zinc-based alloy plate, and a lubrication mechanism connected to the sliding feet and provided corresponding to the lifting mechanism. A hydraulic sliding foot device for an injection molding machine proposed in Patent CN215434724U uses a proportional pressure reducing valve and a one-way valve, and the pressure value can be set so that the oil cylinder can push the moving plate moving part upward to solve the problem that the height of the moving plate moving part needs to be adjusted manually in a traditional injection molding machine. The disclosed technologies fail to solve the problems of large friction resistance, high noise, and difficult position adjustment when the moving template moves horizontally on the machine frame guide rail surface.

[0004] The utility model proposes a rolling sliding foot device for a horizontal squeeze casting machine, which utilizes the principle of rolling friction to manipulate the smooth and low-resistance movement of the moving template on the machine frame guide rail surface. It has the characteristics of low friction, low noise, and high versatility, can fully reduce the starting and running resistance of the moving template of the squeeze casting machine, thereby reducing the energy consumption of the squeeze casting machine and improving production efficiency. It is of great significance for improving the performance of the horizontal squeeze casting machine, reducing energy consumption, and improving the operating environment.

[0005] It should be noted that the above information disclosed in this background art section is only for understanding the background art of the inventive concept of the present utility model, and therefore, it may include information that does not constitute the prior art. Summary of the Utility Model

[0006] The prior art uses sliding friction type sliding feet with relatively large frictional resistance. The clamping cylinder needs to apply a relatively large pressure to push the moving platen to move horizontally on the frame guide rail surface, resulting in relatively high energy consumption. In particular, when the lubrication is poor, the resistance of the sliding friction type sliding feet rises sharply, and at the same time, a harsh frictional sound is emitted. In view of the above problems, the present utility model proposes a rolling sliding foot device for a horizontal squeeze casting machine, which consists of an adjusting mechanism, a lubricating oil nozzle, and a rolling sliding foot. By adjusting the rod to adjust the relative position between the adjusting plate and the supporting plate, fine adjustment of the gap between the rolling sliding foot and the frame guide rail surface is achieved. The lubricating oil nozzle is installed on the side of the supporting plate to facilitate regular lubrication of the needle rollers. The adjusting mechanism and the rolling sliding foot are fixed on the supporting plate by screws to form an integral module.

[0007] The technical solution adopted by the present utility model is as follows:

[0008] 1) Replace the traditional sliding friction type sliding feet with rolling sliding feet. The rolling sliding feet are composed of needle rollers and needle roller seats. The needle rollers roll freely in the needle roller seats, and the horizontal movement of the moving platen is realized through the contact between the needle rollers and the frame guide rail surface.

[0009] 2) The interior of the needle roller seat is designed with a needle roller track to ensure that the needle rollers maintain a stable movement trajectory during the rolling process. The needle roller seat is made of wear-resistant materials and has good wear resistance and impact resistance.

[0010] 3) Dust scraping and oil scraping plates are arranged on both sides of the rolling sliding feet to remove dust and oil on the track surface and keep the needle rollers and the guide rail surface clean. At the same time, a lubricating oil nozzle is arranged on the supporting plate to facilitate the operator to regularly add lubricating oil to the needle rollers to ensure good lubrication of the rolling sliding feet.

[0011] 4) An adjusting mechanism is equipped to adjust the gap between the rolling sliding feet and the frame guide rail surface to meet the moving requirements of different precisions. The adjusting mechanism includes an adjusting rod, an adjusting plate, and a supporting plate, and fine adjustment of the gap is achieved by rotating the adjusting rod.

[0012] 5) In order to enhance the versatility of the device, a modular design concept is adopted, which is convenient for customization and replacement according to different models of horizontal squeeze casting machines. At the same time, the rolling sliding feet are designed as standard parts, which is convenient for procurement and replacement in the market.

[0013] The present utility model has significant advantages and beneficial effects compared with the prior art, which are specifically reflected in the following aspects:

[0014] (1) Small frictional resistance: Adopting the principle of rolling friction, it significantly reduces the frictional resistance during the movement of the moving platen, reducing the working pressure and energy consumption of the clamping cylinder;

[0015] (2) Low frictional noise: The frictional noise generated by the rolling slider during operation is much lower than that of the traditional sliding friction slider, improving the comfort of the operating environment;

[0016] (3) Strong versatility: Adopting the modular design and the idea of standard parts design, this device has strong versatility and is applicable to horizontal squeeze casting machines of different models. At the same time, an adjustment mechanism is designed to adjust the gap between the rolling slider and the guide surface of the frame to adapt to the movement of the moving platen with different accuracy requirements;

[0017] (4) Convenient maintenance: The design of the dust-proof oil scraping plate and the lubricating oil nozzle makes the maintenance of the rolling slider more convenient and simple, reducing the maintenance cost and difficulty.

[0018] Specifically, the characteristics of the present utility model lie in including an adjustment mechanism, a lubricating oil nozzle and a rolling slider; the adjustment mechanism includes an adjustment plate, a support plate and an adjustment rod; the adjustment plate and the support plate have mutually paired inclined surfaces, and the angle of the inclined surface is 10 - 30°; the adjustment rod is a bolt-like structure; the external thread surface at one end of the adjustment rod is inserted into the side surface of the adjustment plate, and the head at the other end of the adjustment rod has an internal hexagonal feature, and the head of the adjustment rod is stuck on the side plate of the support plate; the lubricating oil nozzle is installed on the side surface of the support plate; the rolling slider is fixedly installed at the bottom of the support plate; the rolling slider includes needle rollers, needle roller seats and dust-proof oil scraping plates; the needle rollers are installed in the needle roller seats and can circulate and roll in the needle roller seats. The angle of the mutually paired inclined surfaces of the adjustment plate and the support plate is 15°; the number of lubricating oil nozzles is the same as the number of rolling sliders; the oil passage outlet communicated with the lubricating oil nozzle is located in the area on the lower surface of the support plate where the rolling slider is assembled; dust-proof oil scraping plates are arranged on both sides of the rolling slider.
