PROBLEM TO BE SOLVED: To provide a mold closing adjustment method of a toggle type injection molder, which can stably acquire desired mold closing force when executing a heat and cool molding method.SOLUTION: When a heat and cool molding method is executed in a toggle type injection molder (1), mold closing force is adjusted in a mold closing process. The mold closing process comprises: a first step for driving a cross head (12) to a mold closing position and mold-closing a mold (18, 19) so that the mold closing force becomes a fine contact state; a second step for executing mold thickness adjustment; and a third step for driving the cross head (12) to a mold closing completion position for generating desired mold closing force. Temperature rise of the mold (18, 19) is completed before starting of the second step, and the second step is configured so that when the mold closing force detected in the contact state exceeds a standard range, the mold thickness is adjusted so that the mold closing force falls within the standard range. Then, when the third step is executed, the desired mold closing force is acquired.SELECTED DRAWING: Figure 2 |
