Description

High density triple die holder assembly

Technical Field

The present invention relates to a mold support, and more particularly to an assembly of multiple mold supports to increase the throughput of glove production lines in the glove industry.

Background

Gloves protect our hands from infection and contamination, and therefore it is important to wear gloves when using harmful chemicals and other materials. The use of gloves places demands on the manufacture of the glove industry.

Existing apparatus for manufacturing gloves include multiple mold supports. However, such a device design is vertically arranged, which takes up more space when assembling multiple mould carriages, so that only a smaller number of mould carriages can be assembled on the movable chain, which will affect the overall production of the gloves. Furthermore, the instability of holding multiple mold holders together also significantly affects glove production.

Several solutions exist to increase the output of glove production lines in the glove industry, and a partial solution will be discussed below:

WO2015142155a1 discloses an improved dual mould support assembly for use in the production of products such as medical gloves during high speed latex impregnation. The dual-mold rack assembly consists essentially of a U-shaped bracket attached to two tapered L-shaped arms having an upright plate and a rectangular base plate. The U-shaped bracket has a base, two vertical ends and a pivot rod. Each rectangular base plate of the two tapered L-shaped arms is used to hold at least one mold holder. In the closed position, the upright portions of the tapered L-shaped arms are aligned back-to-back with one another. In the open position, the two L-shaped arms and the mould holder can perform an arc movement of up to 150 °.

MY-168511-A discloses a triple mold support assembly for use in glove manufacturing. The triple die holder assembly consists of a middle link arm sandwiched between two opposing side link arms in a hinged joint mechanism, each link arm having a die holder for carrying a die. The three link arms are mounted on a hinge joint mechanism that includes a C-shaped bracket, a pin, and an R-clamp for the pin. The hinge joint mechanism fixedly arranges the three link arms in position and provides a way to rotate about the pin to accommodate the requirements of the glove manufacturing process. The hinge connecting mechanism is arranged on the conveying chain through a connecting shaft. Bearings on each connecting shaft facilitate movement of the conveyor belt along the glove production line.

Accordingly, it can be seen from the prior art that there is a need for an improved mold support assembly to increase the throughput of glove manufacturing lines in the glove manufacturing industry.
