Hot runner mold

Abstract

The invention discloses a hot runner mold which comprises a main feed inlet, an ear plate, bolts, a heating runner pipe, a heating plate, a main discharge hole, an upper mold plate, a mold cavity, a lower mold plate, a controller, a base, a water pump, a cooling pipe and a water tank. The lower mold plate, the controller, the water pump and the water tank are arranged on the upper surface of the base; the water pump is connected with the water tank and the cooling pipe; the upper mold plate is arranged above the lower mold plate; the bolts are arranged on four corners of the upper mold plate;the mold cavity is arranged between the upper mold plate and the lower mold plate; the heating runner pipe is arranged in the center of the upper surface of the upper mold plate; the main feed inlet is formed in the upper side of the heating runner pipe; the heating plate is arranged in the heating runner pipe; and the main discharge hole is formed in the lower side of the heating runner pipe. Thehot runner mold provided by the invention is simple in structure and convenient to operate; and water in the water tank can be extracted into the cooling pipe through the water pump, and raw materials in the mold cavity can be accelerated-cooled through the cooling pipe, so that not only is the production time saved, but also the production efficiency is improved.

Description

technical field [0001] The invention relates to a hot runner mold, which belongs to the technical field of hot runner injection molds. 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 the traditional mold and saves more raw materials, the hot runner mold has been widely used in various industrial developed countries and regions in the world today. Application, the advantages of hot runners are: 1. shorten the molding cycle of parts; 2. save plastic; 3. reduce waste products and improve product quality; 4. production automation; .The price of hot runner components is relatively expensive, and the cost of hot runner molds may increase significantly; 2. Compared with cold runner molds, the operation and maintenance of hot runner molds is complicated; 3. The production process equipment requires high requirements, and hot runner molds require precisi...
