Abstract

The invention discloses a temperature-controllable injection mold. The temperature-controllable injection mold comprises a movable mold body and a fixed mold body. The movable mold body comprises a movable mold plate, a mold core installed on the movable mold plate and an ejecting mechanism. A cavity formed after the movable mold plate, the fixed mold body and the mold core are closed serves as a mold cavity. A main runner hole communicated with the mold cavity is formed in the fixed mold body. A main runner pipe is tightly installed in the main runner hole. The main runner pipe is a long hollow pipe. An inlet is formed in one end of the main runner pipe, and an outlet is formed in the other end of the main runner pipe. Electric heating elements and temperature sensing elements are arranged in the fixed mold body and the movable mold plate. According to the temperature-controllable injection mold, real-time monitoring and rapid stability compensation of the temperature of the mold can be achieved in the injection molding process, and the main runner pipe can be replaced according to requirements so that injection molding of materials with different injection molding requirements can be conducted on one mold; the injection mold is simple in structure, durable and suitable for the injection molding process.

Description

technical field [0001] The invention relates to a temperature-controllable injection mold, which belongs to the technical field of injection molding. Background technique [0002] Injection mold (Injectionmold) is a processing method used in the mass production of certain complex-shaped parts, mainly used in the industrial field. The process of injection molding is to inject the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. The mold is mainly composed of pouring system, molding parts and structural parts. Among them, the gating system The gating system is also called the runner system. It is a set of feeding channels that guide the plastic melt from the nozzle of the injection machine to the cavity. It usually consists of a main channel, a runner, and a gate. A passage connecting the nozzle of the injection molding machine to the runner or cavity. The entrance of the main channel is connec...
