Detailed information

Product introduction
Jd-361-a hot box core shooter is a kind of vertical parting, semi-automatic, up turning mold, manual core taking hot box core shooter. It is suitable for the requirements of small and medium-sized workpieces in valve, faucet, hardware, hydraulic and pneumatic industries. It is suitable for resin series hot box sand and coated sand core. In particular, it can meet the requirements of copper and aluminum casting industry, adopting three component resin, complex shape and low structural strength hot box process (suitable for molding sand with poor fluidity).
3-2 main components
1. Sand bucket:
The sand bucket (1-t58) is located on the upper side of the column (1-t01) for storing and transporting sand cores. Its a square cone groove.
2. Sand shooting device:
When the swing arm (1-t18) swings under the sand bucket seat (1-t19), the sand core in the sand bucket (1-t58) falls into the sand shooting pipe (1-t65) through the mouth of the sand bucket; when the swing arm (1-t18) swings to the sand shooting position, the oil cylinder (1-b38) acts, the sand shooting inlet head (1-t61) moves downward, and the large spring (1-t64) is pressed to realize the sand shooting action.
3. Pneumatic control system:
1) The whole driving system adopts pneumatic driving device, and uses gas pressure to drive the cylinder to complete the whole working process, which has the advantages of no noise and stable operation;
2) Adjust the length of time and the size of gas pressure, realize the adjustment of sand adding quantity, auxiliary cylinder, sand shooting and other working conditions, which is convenient and reliable;
3) The gas storage tank is made of Q235 steel plate. The gas is stored in the column (1-t01). Its working pressure range is 0-1mpa

Use and maintenance
Application of jd-361-a core shooter
5-1 preparation before commissioning
1. Check whether the air pipe and power supply are connected properly;
2. Thoroughly remove the dust, dirt and tools that may be left on the machine after installation;
3. Whether the machine is in the mold open state to ensure the safety of the operator;
5-2 mold installation and adjustment
1. Installation of left and right moulds:
According to the requirements of the core box, first place the core pushing rods of the dynamic and static molds, and then fasten the left and right molds to the mounting plate (heating plate) with four M8 hexagon screws
A turn the control panel switch to manual
B close the ball valve in front of the clamping cylinder
C. start the mold closing switch. After the core rod returns to its position, turn the mold closing switch to the middle position
2. Shooting plate installation:
Connect the nozzle with six m8x30 hexagon socket screws and connect the cooling water pipe
3. Die adjustment
1) Center adjustment:
Move the ejector head to the working position, adjust the mobile hand wheel of the movable frame and the adjusting screw of the workbench to make the mold center and the ejector head center most accurate
2) Closing gap adjustment:
Adjust the positioning screw of the fixed die to make the left and right half die close and clean the seam
4. Installation and adjustment of core pulling block:
1) Move the movable block to a proper position and fasten it
2) Adjust the movable block to move the upper and lower dead points and fasten them
2) The up and down stroke is adjusted by the limit rod
Carry out the following maintenance regularly
1. Pay attention to keep a certain amount of oil in the atomizer;
2. At the end of each work shift, the sand shooting head must be removed to clean up the accumulated sand, and the sand in the exhaust plug must be blown off;
3. At the end of each work shift, the accumulated sand on the worktable and column must be completely removed;
4. At the end of each work shift, the remaining sand in the sand bucket must be removed and the inner wall of the sand bucket must be wiped clean, so as not to affect the work due to hard sand accumulation;
5. At the end of each work shift, the condensed water in the machine and main pipe must be drained;
6. All electrical circuits and contacts must be checked frequently, otherwise the cable insulation is damaged and the terminal block of the box is loose, which will cause great loss;
7. Repair the machine once a month and check the sealing surface;
8. Clean the sand in the muffler frequently to ensure its smoothness;
