Injection mold convenient for cooling molding

Abstract

The invention discloses an injection mold convenient for cooling molding. The injection mold comprises a movable mold base and a static mold base; the movable mold base is fixed on a movable worktable; the static mold base is fixed on a static worktable; a convex mold insert is fixed in middle of the movable mold base, and is inserted in a concave mold insert; the concave mold insert is fixed in middle of the static mold base; a heat absorbing pipe is wound on the outer side of the concave mold insert, and is positioned in the static mold base; a liquid inlet of the heat absorbing pipe communicates with a liquid outlet of a water pump through a liquid inlet pipe; a liquid inlet of the water pump communicates with a water tank through a water pipe; the water pump and the water tank are bothfixed in a mounting box; the mounting box is positioned under the movable mold base and the static mold base; a liquid outlet of the heat absorbing pipe communicates with a liquid outlet pipe; the liquid outlet pipe communicates with a heat dissipating mechanism; and one side of the heat dissipating mechanism communicates with the water tank. Through the structure, the quick cooling of the mold is realized, the cooling time is short, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of injection molds, and in particular relates to an injection mold which is convenient for cooling and shaping. Background technique [0002] With the rapid development of the plastics industry, plastic products are used in various fields of life and production. Injection molding is a processing method used in the mass production of certain parts with complex shapes. When plastic products are injected, the mold is clamped in the injection molding On the machine, the heated and melted material is injected into the molding cavity by high pressure, cooled and formed in the cavity, and then the dynamic and static molds are separated, and the product is ejected from the cavity through the ejector system to leave the mold, and finally the mold is closed again for the next step. One injection molding, the whole injection molding process is carried out in a cycle. [0003] After the heated and melted material is in...

Problems solved by technology

[0004] The purpose of the present invention is to provide an injection mold that is convenient for cooling and shaping, so as to solve the above-mentioned background technology that the existing injection mold cooling circulation water does not have a heat sink, which leads to a block of water temperature rise, resulting in poor heat absorption efficiency for the mold, resulting in product molding. The problem of long time and poor molding quality
