Description

Multi-contact single-cylinder mold ejector with sand scraping mechanism

technical field

The utility model is suitable for the foundry industry and the field of sand molding, in particular to a multi-contact single-cylinder mold lifting machine with a sand scraping mechanism.

Background technique

After the sand mold is formed by the molding machine, whether the mold can be lifted smoothly is the key to determine the quality of the sand mold. In the prior art, the mold lifting method of the molding machine adopts the method of single-cylinder mold lifting and two auxiliary cylinders, but this mechanism is difficult. Realize the synchronization between the main and auxiliary cylinders, which seriously affects the quality of the molding sand; or some use double cylinders to lift the mold, but due to the lack of synchronization between the two cylinders, the mold is not stable when the mold is lifted, which also affects the quality of the sand mold.

Utility model content

In order to solve the above-mentioned technical problems existing in the prior art, the utility model provides a multi-contact single-cylinder molding machine with a sand-scraping mechanism, including a molding mechanism and a sand-scraping mechanism, and the sand-scraping mechanism is located at the Above the mold mechanism; the mold lifting mechanism includes a single mold lifting cylinder, the mold lifting cylinder is fixed on the base, a plurality of guide pillars are arranged on the base around the mold lifting cylinder, the upper end of the guide pillar is provided with an upper seat, the upper seat, the guide pillar and The base forms a whole; the carriage slides on the guide post between the upper seat and the base, and is connected with the piston rod of the ejector cylinder. When the piston of the ejector cylinder expands and contracts, it drives the carriage to move up and down, and the ejector arm is fixed on the carriage. , the ejector pin and the ejector pin support are fixed on the ejector arm.

Further, the position of the ejector pin on the ejector pin support can be adjusted.

Further, the ejector pin is provided with an ejector top.

Further, there are four guide posts.

The multi-contact single-cylinder mold lifting machine with a sand scraping mechanism of the utility model adopts a four-guide pillar guiding mechanism, and self-lubricating bearings are used between the carriage and the guide pillars. Through their precise cooperation, the up and down movement of the carriage is guaranteed. Stable and stable, the ejector arm is made of ductile iron, which improves the rigidity of the component, thereby achieving the purpose of smooth ejection and improving the quality of the sand mold.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1-3, the multi-contact single-cylinder mold pulling machine with a sand scraping mechanism of the present invention includes a mold lifting mechanism and a sand scraping mechanism, and the sand scraping mechanism is arranged above the mold lifting mechanism.

Described ejecting mechanism comprises single ejecting cylinder 1, and ejecting cylinder 1 is fixed on the base 2, and a plurality of guide pillars 3 are arranged on the base 2 around ejecting cylinder 1, and upper end of guide pillar 3 is provided with upper seat 4, upper seat 4 , the guide post 3 and the base 2 form a whole; the carriage 5 slides on the guide post 3 between the upper seat 4 and the base 2, and is connected with the piston rod of the ejector cylinder, and when the piston of the ejector cylinder stretches, it drives the carriage 5 for Moving up and down, the ejector arm 6 is fixed on the carriage 5, and the ejector rod 7 and the ejector rod support 8 are fixed on the ejector arm 6, so that when the ejector cylinder piston moves, the carriage and the ejector arm are driven to achieve The purpose of starting the mold. The position of the ejector pin 7 on the ejector pin support 8 is adjustable, and the ejector pin 7 is provided with an ejector pin 9 .

When the multi-contact single-cylinder mold lifting machine with a sand scraping mechanism of the utility model is used, the equipment starts to run automatically, and shocks are carried out according to the process flow. When it is in place, the multi-contact cylinder starts to compact. After the compaction is completed, the compaction head cylinder starts to retreat. After the retreat is in place, the sand-scraping mechanism pushes forward to scrape the sand, and the mold is ejected after completion.
