Problems solved by technology

[0004] The existing heating method usually uses electric heating, that is, the electric heater stops supplying heat when the temperature reaches the preset value, and continues to provide heat when the temperature is lower than the preset value. Unstable temperature inside the mold
In addition, using electric heating, the mold will be in the cooling state of natural convection, which makes it easier to make the temperature of the mold unstable

Embodiment Construction

[0013] Please see figure 1 and figure 2 , the mold 100 includes a module 10 , a heating rod 20 penetrating in the module 10 and a cooling channel 30 opened in the module 10 . The heating rod 20 provides heat for the module 10 , and the cooling channel 30 absorbs excess heat 10 of the module 10 to maintain the module 10 at a certain temperature.

[0014] The module 10 is in the shape of a cube, and a cross-shaped flow channel 120 is recessed in the middle part. Analyzed from the transverse direction x of the module 10 , the module 10 can be divided into a forming zone 12 , a heating zone 14 outside the forming zone 12 and a cooling zone 16 inside the forming zone 12 . Analyzed from the longitudinal direction z of the module 10 , the module 10 is divided into three layers: an upper layer 11 , a lower layer 13 , and a middle layer 13 between the upper layer 11 and the lower layer 15 . The forming zone 12 , the heating zone 14 and the cooling zone 16 are respectively located o...

Abstract

The invention provides a mould, which comprises a mould block, a cooling duct and a heating rod, wherein the mould block is provided with a die cavity; the heating rod provides heat for the mould block; and the cooling duct is used for absorbing the heat of the mould block. From the vertical direction of the mould block, the heating rod and the cooling duct are respectively positioned at two sides of the die cavity.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for injection molding. Background technique [0002] When injection molding processes a workpiece such as a molded lens, hot melt plastic is injected from the injection port and flows into the cavity for molding. However, the plastic will cool during the injection molding process, the cooling of the plastic will increase the injection pressure, and gaps will be formed on the melting surface, and the formation of gaps will affect the quality of the lens. Therefore, it is necessary to increase the temperature in the injection mold to reduce the phenomenon of gaps and improve product quality. However, if the temperature of the injection mold is increased, it is not conducive to the cooling of the product, resulting in a longer injection cycle. [0003] In order to achieve the purpose of improving product quality and production efficiency, the existing injection molds generally need to be maintaine...
