Problems solved by technology

[0002] At present, the injection mold is a processing tool used in the mass production of certain parts with complex shapes. At present, the working principle of the traditional injection mold is: the heated and melted material is directly injected into the mold cavity by high pressure. After curing, a molded product is obtained, but at the same time as the molten material is injected, due to the high temperature of the material, the temperature drops sharply after entering the mold cavity, causing the molten material to solidify during the flow process, not only will there be blockage, The flow rate decreases and the quality of the molded product is affected

Abstract

The invention discloses an injection mold with high forming quality. The injection mold comprises mold bases and a cavity, the cavity is in the mold base, a plurality of electric-heating rods and cooling pipes are arranged in the mold base, the electric-heating rods are uniformly arranged in a mode of surrounding the cavity, the cooling pipes surround the four corners of the cavity, the mold base is further provided with a sprue gate, the sprue gate is communicated with the cavity, the mold base around the sprue gate is further provided with the plurality of electric-heating rods. According to the above mode, the sudden temperature dropping of the molten material is prevented in the sprue process, thereby preventing the molten material from curing in advance to cause the blocking so as to improve the quality of the formed product.

Description

technical field [0001] The invention relates to a mold, in particular to an injection mold with high forming quality. Background technique [0002] At present, the injection mold is a processing tool used in the mass production of certain complex-shaped parts. After curing, a molded product is obtained, but at the same time as the molten material is injected, due to the high temperature of the material, the temperature drops sharply after entering the mold cavity, causing the molten material to solidify during the flow process, not only will there be blockage, The flow rate decreases and the quality of the molded product is affected. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-quality injection mold, which can prevent the temperature of the molten material from dropping sharply during the pouring process, thereby preventing the phenomenon of clogging caused by the early solidification of the molten m...
