Abstract
The present application provides: first base members that respectively hold split molds disposed at both ends in a second direction, and are fixed to a mold clamping plate; second base members disposed between the first base members and having the split molds other than the split molds fixed to the first base members fixed thereto; and coupling members that couple the first base members and the second base members in a state that allows each of the pair of split molds to come into contact or separate. The present invention is configured such that the plurality of second base members follow the movement of the first base members.
Claims11
A blow molding mold that includes a blow mold including:
- a pair of split molds forming a plurality of cavities arranged in a row in a first direction;
- a plurality of bottom molds respectively corresponding to the cavities;
- and a bottom mold fixing plate to which the plurality of bottom molds are fixed, the blow molding mold comprising:
- at least three blow molds arranged in a second direction perpendicular to the first direction;
- first base members holding split molds that are arranged at both end positions in the second direction, the first base members being fixed to a mold clamping plate;
- second base members arranged between the first base members;
- and
- a coupling member configured to couple the first base members and the second base members in a state where the pair of split molds are contactable with and separable from each other,
- wherein the second base members are configured to move in accordance with movement of the first base members, and
- wherein a moving distance of each second base member is shorter than that of each first base member when the blow molds are opened or closed.
A blow molding mold that includes a blow mold including:
- a pair of split molds forming a plurality of cavities arranged in a row in a first direction;
