Automatic molding Machine , Automatic static pressure molding machine for Sand casting
Main technical features of Automatic static pressure molding machine
1. Sand molding machine
1.1 main structure of sand moulding machine
Foundry Static pressure moulding machine is considered to be the ideal modeling method for tidal sand. Its equipment is mainly composed of louver sanding bucket, multi-piston, residual sand frame, formwork frame, lifting table, template changing device, upper frame moving device, The composition of the external quick change plate device (the quick change plate is an option), the compact process is divided into four processes:
(1) sanding ( fill sand)
In the natural drop method, the sand is filled into the sand box and the residual sand frame by the weighed quantitative sand through the louver type sand hopper.
(2) Compaction
The sand type is finally compacted under the compaction of multiple contacts, and the compaction specific pressure can be adjusted within the range of 0.2~1.5Mpa.
(3) pattern draw
The template is separated from the mold by a back-feed mold.
(4) Template conversion
The rotary table rotates 180 degrees to switch between the upper and lower modes.
Automated sand molding line
The static pressure molding machine designed by our company has the following characteristics:
(1) The upper frame is moved laterally relative to the side roller frame, and the scattered sand in the moving and the residual sand scraped off after sanding are returned to the underground sand belt through the chute, and will not fall on the stencil and the unshaped sand box surface. on.
(2) The design of the workbench cylinder has two-stage stroke, the position of the connection box is accurate, and the method of positioning by hydraulic valve is adopted.
(3) Multiple pistons are key components, and the multiple pistons currently used are single cylinders.
l Imported seals are used, and the rods are scraped and sealed with "Stern seal" and U-ring. The joints are sealed and sealed to ensure no leakage. Moreover, the seal is filled with PTFE, which can be semi-permanent and long-lived.
(4) The rod end is secondly guided, and the secondary dusting causes the lateral load to cause partial wear and sand sand to enter and accelerate wear.
(5) Lengthen the width of the guide ring of the piston and the rod end to reduce the contact stress caused by the partial load, reduce wear and pull the cylinder.
(6) The multi-piston lower cavity does not use the multi-contact body radial oil inlet method. Many contacts cannot guarantee that each one is high precision, and the O-ring is easy to be scratched during assembly. The line adopts the section oil inlet mode, and the multi-contact body is ground on the surface to ensure the gap-free O-ring seal to ensure no leakage.
l The first stage of the multi-contact rod is guided by SF-1 composite material, which is resistant to lime sand.
l The multi-contact has a demoulding slope and a non-stick sand polyethylene layer is adhered underneath, so that there is no sand when compacting the return stroke.
(7) Weighing and sanding. According to the model and the need to press out the back and height of the flask. Set the amount of sand to be adjusted, and the height of the sand filling frame is designed according to the excess.
(8) Rotary type plate replacement device is adopted, and two types of upper and lower type plates are placed on the turntable, and each type is replaced, and the type is made up and down.
(9) The die-lifting device is equipped with a thickened piston rod and a guide rod, and the hydraulic system is set to a slow-starting mold, which is lowered rapidly to ensure a smooth condition.
(10) The hydraulic cylinders of the workbench are controlled by electro-hydraulic proportional hydraulic valves. The rotary table and the upper frame mobile terminal are also equipped with a West Czech buffer, which is fast, accurate and shock-free. Ensure that the machine's operating time can meet high productivity requirements.
We are professional Abrator; Mixing Equipment;Metal Casting Machinery manufactuer over20 years in China , there are so many kinds of foundry machines , they are sand muller /mixer , sand molding machine , sand core making machine , shot blasting machine and otherautomatic casting line.
Since its founding in 1998 as Qingdao Huaxin Group, the mission of qingdao huaxin group has been to develop the most innovative solutions possible for the automation of green sand moulding, sand core making machine, sand preparation and shot blasting processes throughout the foundry industry. Continuous technological improvement and innovation have earned nearly 20 intellectual property rights in China.
Today, with nearly 5,000 sand moulding machines and shot blasting systems installed around the world, and its sales and service operations are spread all over the world. Our single focus is, has always been, and will always be the foundry industry.
Qingdao Huaxin Group has over 20 years history In China. It is located in Binhai Industrial Park, Huangdao Area, Qingdao city,China. It is covered an area of sixty-six thousand six hundred and sixty-seven Square meters. We have produced foundry machines more than 1000 types, so we have rich experience in sand casting production machines. The casting production line is Automatic horizontal static pressure molding line, Auto shell molding line, Furan resin sand automatic molding line, Green sandl processing production line(Sand Preparation); the newest patent machine-continuous sand mixer,pouring machine, popular standard machine are Jolt squeeze molding machine, pneumatic multi-piston molding machine, all kinds of cold core / hot core box core shooting machine, various shot blasting machines. We provide excellent supporting equipment and services for China's foundry, shipbuilding, automobile, locomotive, machine tool and other industries. We design and manufacture various non-standard special casting machines according to user needs.
For newly invested foundries, automatic casting line is the first choice, but in the process of consultation, we must be clear about several key points:
1. what is flask size ?
2. What is the required producing capacity?
3. Do you need core setting section ?
4. What is the cooling time after pouring ?
5. How many are pouring stations?
6. What is the capacity of your electric furnace? How many stoves are there together?
7. How many tons of molten iron in one hour?
8. What is the weight of a box casting?
9. Please provide the factory layout , after comfriming all detail message , we will design it according to your drawing,
10. Or you can tell us your Budget.
