Mold for water dropper forming

Abstract

The invention discloses a mold for water dropper forming. An A mold body and a B mold body which can be buckled are included; the A mold body comprises an A base and four sets of independent mold cores installed above the A base in a protruding manner; the four sets of mold cores are arranged into two rows, and two sets of mold cores are arranged in each row; each set of mold core comprises two oblong core bodies side by side in a left-right spaced manner, and the two opposite side edges of every two core bodies are each provided with eight up-down through water dropper mold cavities with semicircular cross sections; the water dropper mold cavities on the two side edges are opposite left and right, and a cylinder mold core is arranged between every two opposite water dropper mold cavities;each core body is provided with two positioning small holes, and four positioning large columns are arranged at the four corners of the A base; and the B mold body comprises a B base and six positioning sealing bases fixed to the B base. The mold cost is saved, it is avoided that after whole plate structure mold core abrasion, a mold core is replaced as a whole, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hot runner moulds, in particular to a mold for dripper molding. Background technique [0002] The hot runner mold is a mold that uses a heating device to keep the melt in the runner from solidifying. Because it has a shorter forming cycle than traditional molds and saves more raw materials, hot runner molds are widely used in various industrially developed countries and regions in the world today. [0003] However, the existing traditional molds have the following shortcomings: 1) The traditional mold core adopts a whole-plate structure, and the mold core needs to be replaced as a whole after the mold core is worn out, resulting in a great waste of mold steel and high replacement costs. In addition, the whole-plate structure mold During the use of the core, it is easy to cause serious wear and tear; 2) The traditional mold core adopts a recessed structure, that is, the core is embedded in the substrate, ...

[0003] However, the existing traditional molds have the following shortcomings: 1) The traditional mold core adopts a whole-plate structure, and the mold core needs to be replaced as a whole after the mold core is worn out, resulting in a great waste of mold steel and high replacement costs. In addition, the whole-plate structure mold During the use of the core, it is easy to cause serious wear and tear; 2) The traditional mold core adopts a recessed structure, that is, the core is embedded in the substrate, and the recessed structure is prone to poor heat dissipation, resulting in heat accumulation, which
