摘要： PURPOSE:To replace a stamper by removing a mirror board by using an inner peripheral ring with a stamper fitting into its center and an outer ring fitting on the outer periphery and fitting the inner peripheral ring in a guide component to accommodate the mirror board in a recessed section and fitting said unit in an insert die integrally. CONSTITUTION:The mold surface side of an insert die 5 to be accommodated in the center of a base mold 3 is formed on a round recessed section 7 and a guide component 11 of short cylindrical shape is provided projectingly on the center of the recessed section, and a mirror board 16 which is mounted on the mold surface by means of an inner peripheral ring 18 fitted with a stamper 21 fitted in its center and an outer peripheral ring 20 fitted on the periphery, is fitted in the recessed section 7 by fitting the inner peripheral ring 18 in the guide component 11 and fixed in the insert die 5 integrally. Thus, the stamper 21 can be replaced by using the insert die 5 removed from a base mold 3 as a supporting bed, and if necessary, the mirror bed 16 is released from the insert die 5 together with the stamper 21 for the replacement of the stamper. The replacement of the stamper 21 can be carried out easily simply by removing the mirror board 16 in said arrangement.

摘要： PURPOSE:To reduce molding losses by judging the quality of molded items by measuring continuously in the molding of molded items shape accuracy of a molded item which has been judged as a good item based on monitored value during its molding. CONSTITUTION:Molded items are molded under the monitor of a product quality control device 2. A molded item 9 which has been judged as a good item based on monitored value during its molding is transferred to a measuring device 8 after it has left a runner. Shapes of molded item 9 are measured one by one by means of a measuring unit 11 of the device 8 to judge the quality thereof based on size value. Measured data inputted into a measured data processor 12 to input data concerning good items from the device 12 into a product quality control device 2. The molded items 9 from the device 8 are automatically separated into good items and bad items based on the judgment by the unit 11.

摘要： PURPOSE:To enable molding condition to be set with a small volume of data by setting one or more of pseudo relative data of the secondary physical amount based one a primary physical amount, for the primary physical amounts relative to the molding of on imaginary molded object preliminarily by the estimation elements such as intuition and experience, etc. CONSTITUTION:One or at least two of pseudo relative data of the secondary physical amount (flowing pressure, dwell pressure and pressure coefficient, etc.) based on primary physical amount are set for the primary physical amount (thickness and flowing length, etc.) relative to the shape of an imaginary molded object by the estimation elements such as intuition and experience, etc., preliminarily. Next, when molding condition is set, the molding condition (injection pressure, etc.) is calculated on the basis of each relative data stored from the primary physical amount relative to the molding of an actually molded object.
