Mold Jamming Caused by Thermal Expansion Difference Between Product and Mold After Casting

After cooling, the product and the mold are stuck due to different thermal shrinkage. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) In terms of the mold: the thermal expansion coefficient of the material differs too much from that of the mold, the mold structure or condition directly affects the flow and molding of the material in the cavity. (2) Process factors: the demolding draft angle is too small or there is no demolding draft angle, this factor affects the product's '2079851475616104453 and final quality. (3) In terms of materials: fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) In terms of the process: control deviations of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (5) In terms of equipment: equipment precision and maintenance status affect the stable execution of process parameters.

(1) Implementation measures: increase the demolding draft angle (at least 1-2°), formulate a specific operation plan based on actual production conditions and verify the implementation effect. (2) Implementation measures: reserve shrinkage gaps in mold design, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (3) Material selection: choose mold materials with matching thermal expansion coefficients., establish material selection evaluation standards and determine the optimal plan through comparative tests. (4) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

This problem requires comprehensive analysis from multiple dimensions of materials, processes, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
