Problems solved by technology

However, there are great defects in the application of the integral multi-core upper mold made by the existing production method. Because the mold is integral, the small core will be subjected to high temperature and high pressure during the extrusion process, so the small core The head is easily broken and bent, resulting in the scrapping of the entire upper die

Abstract

The invention discloses an integral multi-core upper die comprising a small core and a main body part, wherein the main body part is provided with an inlaying hole and a recess adaptive to the small core, and the small core can be inlayed in the inlaying hole and the recess. By consisting of the main body part and the small core, the integral multi-core upper die can not be discarded if the smallcore is damaged in operation, and can operate normally just by replacing the small core. In addition, procedures get simpler and the production period gets shorter in the production process of the integral multi-core upper die, thereby virtually reducing the production cost and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of mold processing, and more specifically relates to an integral multi-core head upper mold. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. The planar flow splitting combination die belongs to a kind of mould, and the integral multi-core head upper die is a part of the planar splitting combination die. The working principle of the planar splitter combination die is to use a solid ingot. Under the action of the extrusion force of the extruder, the metal is split into several metal streams when passing through the splitter hole, and converged in the welding chamber. The vacuum mold cavity is welded again, and then flows out through the gap formed by the mold core and the mold to form a pipe or hollow profile that ...
