Abstract
A main technical feature of a method for molding and forming a flip-flop and a mold thereof provided by the invention is that when a polymer raw material is filled into a mold chamber space of the mold, the filled raw material is preferentially flowed in a direction of a strap area space used to mold a V-shaped strap portion of the flip-flop to ensure that the slender V-shaped strap portion of the flip-flop can be integrally formed.
Claims14
A mold for molding and forming a flip-flop comprising:
- a first mold plate and a second mold plate capable of displacing relative to each other between a mold clamping position when attaching and connecting with each other and a mold opening position when separating from each other under an action of an external force;
- a mold chamber being a closed space defined between the first mold plate and the second mold plate when the first mold plate and the second mold plate locating in the mold clamping position, the mold chamber having a spatial shape the same as that of the flip-flop and being divided into a sole area corresponding to a shape of a sole of the flip-flop, a strap area corresponding to a shape of an elongated V-shaped strap of the flip-flop, and three hole-shaped connecting areas communicating with the sole area and the strap area respectively and corresponding to positions of three end points of the V-shape;
- and
- three hole-shaped material filling channels respectively provided on the first mold plate and communicating with the mold chamber for an external raw material to enter the mold chamber through each of the material filling channels, and an outlet orifice of each of the material filling channels located on a chamber wall of the mold chamber being respectively facing toward each of the connecting areas.
