Claims

[Scope of Claim for Utility Model Registration] (1) A flow rate adjustment member provided with a communication path that allows the material to flow continuously through the runner section at a predetermined portion of the runner section that guides the material injected from the injection section to the molding cavity. , a position adjustment means for shifting the communication path relative to the runner section by changing the fixed position of the flow rate adjustment member, and by operating the position adjustment means, substantially all of the material in the communication path is moved. 1. A flow rate adjustment structure of a runner part in a molding die, characterized in that the flow rate of the material is adjusted by changing the passage width. (2) By operating the position adjustment means, the opening area of the communication path in the flow rate adjustment member to the runner portion is changed, thereby changing the substantial passage width of the material in the communication path. A flow rate adjustment structure of a runner portion in a molding die according to claim 1, which has become a registered utility model. (3) The position adjustment means includes a first engagement tooth provided on the flow rate adjustment member and a second engagement tooth provided in a fixed position corresponding to the engagement tooth, and Utility model registration claim 1 or 2, wherein the flow rate adjusting member is positioned based on the meshing of the engaging teeth, and the position of the flow rate adjusting member is adjusted by changing the meshing position. The flow rate adjustment structure of the runner part in the molding die described in 2.
