Description

Technical Field

[0001] The present invention relates to the technical field of casting machines, and more particularly to a positioning device for casting machines. Background Art

[0002] A pouring machine is an automated equipment widely used in the manufacturing industry. It is mainly used to accurately inject molten or semi-molten materials, such as plastic, rubber, metal, etc., into a pre-designed mold to produce products with a certain shape and size. The background technology of this equipment covers multiple engineering disciplines, including mechanical engineering, materials science, automatic control, and computer science. In the application of pouring machines, the positioning device plays a vital role. Its main function is to ensure that the mold or workpiece can be accurately placed in the preset position during the pouring process, so that the pouring material can fill the mold evenly and accurately, thereby ensuring the quality and dimensional accuracy of the final product.

[0003] Most of the existing positioning devices for pouring machines require manual adjustment, which is not only inconvenient to operate, but also easy to cause burns to the staff. At the same time, during the pouring process, the force applied to the ladle is dispersed in different directions, which makes the device energy consumption high and easy to move in other directions, posing a safety hazard during the pouring process.

[0004] A Chinese utility model patent with publication number CN212945398U discloses a tilting pouring machine, including a body, a rotating plate movably sleeved inside the body, a baffle fixedly connected to the top surface of the rotating plate, a lifting rod fixedly installed on the top surface of the inner cavity of the body, a ladle provided on the top surface of the rotating plate, a horizontal plate fixedly connected to the right side of the ladle, a fixed plate fixedly connected to the bottom surface of the rotating plate, a lower clamping plate movably connected to the outer surface of the fixed plate, and a vertical plate fixedly connected to the left end of the lower clamping plate. The tilting pouring machine is simple and convenient to operate, and a small number of bolts are used, so that the ladle has a certain stability when rotating with the rotating plate, and the ladle is prevented from slipping, thereby improving work safety. However, when the pouring machine tilts the ladle, it cannot provide an effective and stable limiting effect on the ladle, and the ladle is prone to sliding and shifting, making it difficult to ensure operational safety.

At the same time, it can cooperate with the inclined block 101. During the movement of the movable plate 204, the movable plate 204 squeezes the inclined block 101, so that the positioning plate 109 clamps and fixes the ladle 301 through transmission, so that some functions of the device are carried out synchronously, thereby reducing the time of the pouring process and improving the pouring efficiency.
