High speed fully automatic vertical foundry molding machine for pipe fittings valves manhole covers

A vertical foundry molding machine is a specialized piece of equipment for sand casting that forms molds in a vertical orientation (with the mold cavity opening upward or downward, and the mold halves closing vertically). It is widely used in medium-to-large batch casting production, and its core value lies in improving molding efficiency and mold precision.

Vertical foundry molding machines are designed for sand casting processes, and their applications focus on scenarios that require stable mold quality and high production efficiency, mainly including:

• Automotive industry: Production of engine blocks, cylinder heads, gearbox housings, brake components, and other castings with complex structures and strict dimensional requirements.
• Agricultural machinery manufacturing: Molding of plow parts, harvester gear cases, tractor axle housings, etc.
• Construction machinery field: Casting of excavator bucket teeth, loader frame components, crane counterweights, etc.
• General machinery manufacturing: Production of pump bodies, valve bodies, motor end covers, and other small-to-medium sized castings with symmetrical or regular shapes.
• Rail transit equipment: Molding of rail vehicle bogie components, brake calipers, etc.

Compared with horizontal molding machines and manual molding, vertical foundry molding machines have the following prominent advantages:

• High molding efficiency: The vertical clamping and mold closing structure enables fast cycle times, which is suitable for mass production and can significantly reduce labor intensity.
• Excellent mold precision: The vertical orientation ensures uniform sand compaction, avoids mold deformation caused by gravity in horizontal molding, and guarantees consistent dimensional accuracy of castings (dimensional tolerance can be controlled within ±0.5–1mm for medium-sized parts).
• Low sand consumption: The vertical mold structure reduces the need for excess backing sand, and the sand recovery rate is high, which lowers production costs.
• Good operational safety: The fully automated or semi-automated operation (including sand filling, compaction, mold closing, and ejection) reduces manual contact with heavy molds and high-temperature equipment, minimizing safety hazards.
• Adaptability to complex molds: It can handle molds with deep cavities or multi-level cores, and the vertical mold closing method prevents core displacement during the casting process.

• Vertical structural design: The upper and lower mold halves move vertically to close and open, and the mold cavity is in a vertical state, which is conducive to the smooth filling of molten metal and the discharge of gas during casting.
• Multi-mode sand compaction systems: Common compaction methods include hydraulic pressure compaction, pneumatic jolt-squeeze compaction, and high-pressure compaction, which can be adjusted according to casting size and sand type to ensure uniform density of the mold.
• Integrated automation configuration: It can be connected with automated systems such as sand mixers, core setters, casting conveyors, and mold coolers to form a fully automated production line, realizing unmanned operation from molding to casting.
• Flexible mold change mechanism: Equipped with quick-change mold fixtures, which can complete mold replacement within 10–30 minutes, adapting to the production of different types of castings and improving production flexibility.
• Durable and stable components: The main frame is made of high-strength steel, and the mold clamping mechanism uses hydraulic or servo drive, with high load-bearing capacity and long service life, suitable for continuous 24-hour production.
• Environmental protection features: Some models are equipped with dust collection systems and sand recycling devices, which reduce dust emissions and waste sand discharge, meeting environmental protection standards.
