Claims

[Claims for Utility Model Registration] 1. Concave grooves 15 and 16 are formed so as to constitute a part of the flow path 4 of the molds 1 and 2, and the concave groove 1
A channel opening/closing member for a mold, characterized in that it can be attached to the molds 1 and 2 so that the channels 5 and 16 can be rotated to a position where they no longer communicate with the channel 4. 2 Consists of a cylindrical holder 9 that is inserted and fixed in a non-rotatable manner into the molds 1 and 2, and a cylindrical opening/closing member main body 10 that is rotatably housed within the holder 9,
The grooves are formed in a pair of fixed recesses 15 formed on the inner end surface of the holder 9 and always communicating with the flow path 4, and on the inner end surface of the opening/closing member main body 10.
2. The mold passage opening/closing member according to claim 1, which is characterized by comprising a movable recess 16 that can be rotated to a position that does not correspond to the fixed recess 15. 3. The holder 9 and the main body 10 of the opening/closing member are formed to have the same length, and a backing plate 17 is brought into contact with their outer ends, so that the backing plate 17 and the holder 9
2. The mold passage opening/closing member according to claim 2, which is a registered utility model, characterized in that an accommodation hole 6 for inserting the opening/closing member main body 10 is formed through the molds 1 and 2.
