Description

Technical Field

[0001] The utility model belongs to the technical field of molding machines, and particularly relates to a new type of clay sand molding machine. Background Art

[0002] In the foundry industry, clay sand molding, as a core step in manufacturing castings, is of great importance. The core of this process lies in precisely controlling the compactness of clay sand and shaping it into a sand mold that meets the requirements in a sand box for subsequent pouring and molding. However, the existing clay sand molding machines have some significant limitations in design and function and are difficult to meet the growing demand for foundry production.

[0003] Firstly, most traditional clay sand molding machines use fixtures or chucks with fixed sizes to fix the sand box. Although this design simplifies the operation process to a certain extent, it greatly limits the flexibility of the equipment. With the continuous increase in the types and sizes of castings, the fixtures with fixed sizes can no longer meet all production requirements, resulting in enterprises having to frequently replace equipment or make complex adjustments when facing castings of different specifications, increasing production costs and time costs.

[0004] Secondly, there are deficiencies in the treatment method of clay sand in the existing clay sand molding machines. Many devices directly extrude the clay sand during the molding process, ignoring the key step of vibration treatment. Vibration treatment is crucial for improving the compactness and uniformity of clay sand. It can promote better bonding between sand grains and reduce pores and defects in the sand mold. However, due to the lack of effective vibration devices or insufficient vibration treatment, the existing equipment often fails to achieve the ideal sand mold quality, affecting the overall performance of the castings. Therefore, it is very necessary to invent a new type of clay sand molding machine. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of clay sand molding machine to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a new type of clay sand molding machine, which includes a base, a fixing mechanism, a spring, a mounting frame, a vibration motor, a sand box, a column, a top plate, a first cylinder and a pressing plate. The base is fixed on the ground through expansion bolts, and a fixing mechanism is fixed on the lower side of the base through bolts, wherein the output end of the fixing mechanism faces the mounting frame; springs are respectively fixed at the four corner positions of the upper side of the base, and the upper ends of the springs are fixed with the mounting frame; two vibration motors are fixed on the lower side of the mounting frame through bolts, and a sand box is fixed on the upper side of the mounting frame; a column is fixed on the upper side of the mounting frame through bolts, and a top plate is fixed on the upper side of the column through bolts; a first cylinder is fixed on the upper side of the top plate through bolts, and the output end of the first cylinder is fixed with a pressing plate through bolts, and the pressing plate is arranged above the sand box.

[0008] Furthermore, the fixing mechanism includes a second cylinder, a pressing plate and a sleeve. The second cylinder is fixed on the lower side of the base through bolts, and the output end of the second cylinder is fixed with the pressing plate through bolts, wherein the pressing plate is arranged below the mounting frame; the pressing plate is slidably installed inside the sleeve, and the sleeve is fixed on the upper side of the base through bolts. Such a setting can fix the mounting frame.

[0009] Furthermore, the mounting frame includes a plate body, a lead screw, a clamp, a motor and a U-shaped plate. The four corner positions of the lower side of the plate body are respectively fixed with the upper ends of the corresponding springs, and a lead screw is rotatably installed on the lower side of the plate body through a support bearing; two clamps are threaded through the lead screw, and the clamps are slidably connected with the plate body; one end of the lead screw is fixed with the output end of the motor, and the motor is fixed on the lower side of the plate body; a U-shaped plate is fixed on the lower side of the middle part of the plate body through bolts, and the U-shaped plate is arranged above the output end of the fixing mechanism. Such a setting can fix sand boxes of different sizes, and can pre-treat the clay sand inside the sand box.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The setting of the utility model can clamp and fix the sand box by the cooperation of the motor and the lead screw, so as to fix sand boxes of different sizes, improve the flexibility and adaptability of the equipment, and enable the same equipment to meet various production requirements. Secondly, after the sand box is fixed inside the mounting frame, the synergistic effect of the vibration motor and the spring enables the sand box to generate uniform vibration. This vibration pretreatment method can not only effectively improve the fluidity of the clay sand, but also promote the close arrangement of the sand grains, thus significantly improving the compactness and uniformity of the clay sand. In addition, after the pretreatment of the clay sand inside the sand box is completed, the mounting frame can be fixed through the cooperation of the U-shaped plate and the fixing mechanism, and then the pressing plate is driven by the first cylinder to descend to compact the clay sand in the sand box to form the final sand mold.

When it is not necessary to vibrate the clay sand inside the sand box 6, the second cylinder 21 can drive the pressing plate 22 to move upward inside the sleeve 23 until the upper side of the pressing plate 22 contacts the lower side of the mounting frame 4, so that the spring 3 loses its function due to the pressing force of the pressing plate 22 on the mounting frame 4.

Then, the vibration motor 5 is started to vibrate the clay sand in the sand box 6. After the vibration treatment is completed, the second cylinder 21 drives the pressing plate 22 to move upward to contact the lower side of the mounting bracket 4, and the mounting bracket 4 is fixed by the pressing force.
