technical field

The utility model relates to the technical field of production of solid plastic products, in particular to a die-casting device for production of solid plastic products.

Background technique

Die-casting molds generally include upper and lower parts. After injecting plastic melt into the mold, before the plastic melt in the cavity is cooled and formed, it is necessary to keep the two parts of the mold tightly pressed so that the mold cavity that was not filled is filled with plastic melt. Liquid, wait for the plastic molten liquid to cool and form to complete the die-casting.
