October 13, 2018. Our European customers send us the RFQ to make one set of injection mold for the plug with cable, which was applied in the automotive electronics. They have made one mold for this product in 2016, they need a new mold and want to make some structural improvements. Before this, RYD was not so familiar with this type of mold, but we were confident that we can fulfill our customer’s requirement.
This is the picture of the mold provided by our customer, and the description of the using condition: Our current mold is without ejection, but of course, we would like to have. During the mold opening, the slider will be detached from the mold, and the parts has to be removed manually from the slider.
During the injection molding process, when the mold is opening, the man need to take out the slide which is connected with the products, then fetch out the products from the slide. Begin from the next step, the man need to put the metal inserts into the slide, then install the slide onto the mold. It’s slow, inefficient, and risky. What the customer was saying is that they couldn’t put up with this primitive and inefficient way, which is tedious and unreasonable. Their demand is to make the production automatically, which requires the improvement of the structure of the mold. This is also our pursuit.
This is the picture of the mold provided by our customer, and the description of the using condition: Our current mold is without ejection, but of course, we would like to have. During the mold opening, the slider will be detached from the mold, and the parts has to be removed manually from the slider. So how did we make it? First, as our customer said, there is no ejection system on the formal mold, the product was manually removed from the separated slide. If the new mold requires automatic producing, like other molds do, the ejection system is needed and essential. So we add the ejection system on this new mold design. Second, the metal inserts are located in the slide, during the molding, the products didn’t detach from the slide, the operator need to fetch out the slide and remove the products from it. In this step, we added one linkage structure, when the product is formed, the ejection system starts to push out the product, at the same time, the ejection system drives the slide stripper which is attached with the slide, the stripper pulls the slide away from the products in parallel. So the products drop out from the mold, and strip from the slide. These two steps ensure the automatic production. Another important thing is how to fix the cable wires. There are parts of the wires is outside the mold which may pull down the plug due to the gravity. Therefore, when the mold is installing on the injection molding machine, we add a piece of plate to fix this parts.

During the mold opening, the slider will be detached from the mold, and the parts has to be removed manually from the slider.

Dear Bruce,
Here I want to say that everything was good in the end because the mold was good, thanks to you and the RYD Team, as I said, your idea was excellent.
The most important thing is, the automatic producing makes things efficient, our customer is satisfied with the result. Thank you for all your effort.
Petro
