Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a transmission mechanism which enables a mold component to automatically pre-embed nuts. Background Art

[0002] There are usually three ways to embed nuts in plastic products. The first is to manually place (pre-embed) the nuts one by one in the corresponding positions of the mold. The second method requires making a set of special jigs. The nut positions on the jig need to correspond to the nut positions on the mold. The nuts are then manually placed on the jig, and finally the jig is manually operated to correspond to the mold to achieve one-time placement (pre-embed) of the nuts in the corresponding positions of the mold. The third method is to add a set of vibration plate mechanisms on the basis of the second method to automatically place the nuts on the jig, and then add a set of robot mechanisms to the injection molding machine. The robot adsorbs the nuts on the jig to automatically place (pre-embed) the nuts in the corresponding positions of the mold.

[0003] However, the first method is inefficient because the nuts are placed manually, resulting in a long and uncontrollable production cycle. In addition, the mold temperature during production is usually relatively high, which can easily cause burns. The second method solves the problem of easy burns by adding a fixture, but adds a manually operated fixture corresponding to the process step on the mold, which essentially does not solve the defects of low production efficiency and long production cycle. The third method is an improvement on the second method, which solves the disadvantages of the first and second methods and realizes fully automated production. However, since a special set of robot programs are required for adaptation and professional technicians are also required for subsequent maintenance, the production cost remains high.
