Foundry Moulds TRIZ Cases

A holding jig rotates around an orthogonal shaft to position a core within a drag mold cavity.

A multi-part core uses a longitudinally movable mandrel to displace segments transversely for precise casting formation.

Eddy currents in the feeder reduce cooling gradients, preventing thermal contraction cracking in large castings.

A gas exchange channel rake core uses a tripod configuration of five positioning stops to ensure precise cylinder head alignment during initial casting machining.

An additive using sodium chloride or sulfate balances foaming properties against moisture resistance for complex sand molds.

Vibration-induced dripping creates uniform spherical pellets that reduce resin usage and minimize thermal expansion defects in metal castings.

A die cast system uses a replaceable inner liner insert to change component configurations without reworking the main die housing.

Cover layers applied to joint faces prevent molten metal leakage under high pressure while enabling easy assembly of segmented molds.

A differential pressure casting mold uses suction portions to draw molten metal into a cavity for uniform sheet formation.

Non-bonded casting inserts create interfacial boundaries that absorb noise, avoiding the complexity of added polymer barriers.

Dissolving aluminum silicate in water glass prevents precipitation during storage, ensuring long-term stability for casting molds.

An integrated core molding system combines separate organic and inorganic binder production lines into one facility to reduce capital investment costs.

Sintering infiltrated rare earth cores maintains dimensional accuracy while providing strength for refractory metal intermetallic composites.

Spiral gas passages in tungsten insert dies eliminate water cooling, preventing oxide deposits and boosting production efficiency.

A sizing composition with pH 5 or lower coats water glass-bonded foundry cores to enhance structural integrity and storage stability.

A furan resin binder uses specific metal compounds to maintain mold strength in high humidity.

Spherical fused silica ceramic cores enable precise injection molding of complex turbine blade geometries.

Integrating pivot pin and kidney cores into a single unit removes the finger core, reducing knuckle weight and eliminating core movement defects.

A mold casting device uses a movable die plate on a base member to support the upper mold vertically.

A lubricating composition disperses casting powder in an oily medium to provide effective lubrication during steel casting processes.
