The injection compression molding machine is the use of compressed air injected into the sand box sand evenly pretension real, and then put pressure on the compaction. Common type of injection compression molding machine and the level of vertical type box off box injection compression molding machine. Vertical type tank injection compression molding machine shape without sand box, sand directly into the shape of rooms, with a template made, sand-size precision, sand box has a cavity on both sides, high productivity, but the next core difficulties on the sand stringent quality requirements. Horizontal box off the injection compression molding machine sand box modeling, sand made ​​co-off box, under the core to facilitate high productivity.
The core shooting machine is the use of coated sand core, for the hot core box. The core shooting machine is characterized by the application of two guide pillar, mold opening and closing the vertical type, installed at the same time two different mold, the middle holder sided installation scheduled to die, and around the opening and closing mode (equivalent to the dual frame). Core Shooting Machine is widely used in the foundry industry, the core size core shooting machine manufacturing precision, smooth surface. Core Shooting Machine works will be liquid or solid thermosetting resin binder core sand mixture into the goal after heating of the core box sand core in the core box preheat quickly hardened to a certain thickness (about 5 ~ 10 mm) will be removed to form a smooth surface, precise size, high-quality sand core finished.
Characteristics of the core shooting machine
Z.86F ​​series of core shooting machine for the sand core and shape of the vertical shoot system. The whole structure consists of four parts.
Column parts: the main beam, column constitute the framework of the upper part of the equipment. Sand tube installed on the beam, sand bucket, sand valve parts, compression tanks and other components constitute the core making, sand supply, gas supply system.
(2) sand shooting device: contains the component parts of the sand tube, valves, sand tube rack, radio head, radio sand board. Sand drum work by the compression cylinder compression in the upper plane of the core box, open the sand valve radio radio sand. Exhaust sand shooting finished, release the compression cylinder (returned to the original location) to complete the shooting sand, sand work.
Three mold parts: by moving the template around the bracket plate and guide post, guide sleeve, plunger, mold cylinder parts.
3.1 throughout the mold from the left and right bracket plate mounted on the base.
3.2 The moving platen clamping sliding along the guide post and move around to complete the mold, the mold core making process. Moving the template by the template on the top of the peak of the staff at the top of the core plate mold sand core was the top easily can be removed by hand.
3.3 base: the support of the entire equipment, mold, column, electric control boxes, solenoid valves and other safety on.
