There are many internally threaded products that need to be rotated and pulled out of the mold. Some people call "dental mold" or "
screw tooth mold". The corresponding core parts are like this. In addition to the thread that needs to be removed, the product needs to be pulled out.
Such a very slender core-pulling insert (row insert) must also be cooled by water, but because of its slenderness, it is impossible to drill two pieces of water to rotate, and if it looks like a mold core or Like the inserts, drilling a "well" and then installing a water barrier to isolate the water to form a loop is not feasible here, because the core-pulling insert is too long and the well must be very deep, so the water barrier cannot be installed. So deep.
At this time, a cooling rod can be used, as shown in the figure below. The water
path goes up from the cooling rod. When the water of the cooling rod reaches the top, it goes down to the four sides to form a loop.
The row seat 1 and the row seat 2 are two locked row positions, which are used to fix the core-pulling inserts. The cooling rod is fixed on the row seat 2, so the water inlet and outlet ports are in the row position. On seat 2,
the usage of this cooling rod is suitable for the cooling of threaded shafts or slender rows of some threaded molds. I hope it can be used for your reference.
