Description
Technical Field
The invention relates to the field of mold processing, in particular to a cooling device for a mold.
Background
The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. It is a tool for making blank into product with specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The mold is a precise tool, has a complex shape, bears the expansion force of a blank, and has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, the development level of mold production is one of important marks of the mechanical manufacturing level, the temperature of the mold is very high when the mold is produced, the heat dissipation performance of the mold is low, the cooling time is long, the production speed of the mold is high, the mold is stacked intensively, the heat dissipation efficiency of a mold part is reduced, the mold is easily abraded, and the quality of a product is influenced.
Water has fine heat transfer nature, the main cooling fluid that the blow mould conventionally adopted, hard water will be through softening treatment before leading into the cooling channel in the mould, after the mould uses certain period, hard water is heated in the mould pipeline and evaporates the deposit hard water dirt down, local meeting water course like this may block up, reduce heat transfer performance, traditional mode is mechanical drilling processing cooling water course, this kind of mode is to bore the cooling water hole of length and breadth direction in the blow mould lateral wall, when the cooling water course degree of depth of large-scale blow mould is longer, can adopt the form of two to bore, the drilling is generally bored, it is a plurality of to be equipped with the import and export, all the others are stopped up with the stopper, but this method easily forms the water film, cause the jam of pipeline, there is very big influence to the use of mould. To this end we propose a cooling device for the mould.
Disclosure of Invention
The cooling device for the die solves the problems that a water pipe is easy to form a water film when the die is cooled, and the generated scale can block the pipeline, so that the cooling effect of the die is poor and the like.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a cooling device for mould, includes the mould plate, the inner wall of mould plate is equipped with a plurality of vertical water pipes along its length direction array, two horizontal water pipes have been seted up along its direction of height to the inner wall of mould plate, and is a plurality of the inside of vertical water pipe is equipped with helical blade, the inside interval of horizontal water pipe is equipped with a plurality of jam pipes, the welding of the left side outer wall of mould plate has the inlet tube.
Preferably, the whole interior of the mould plate block is of a hollow structure, and the transverse water pipes and the longitudinal water pipes are communicated in a cross mode.
Preferably, the maximum outer diameter of the blade of the spiral blade is smaller than the inner diameter of the longitudinal water inlet pipe, and the length of the spiral blade is smaller than the distance between the two transverse water inlet pipes.
Preferably, one end of the water inlet pipe close to the mold plate is provided with a water inlet hole, and the water inlet hole is correspondingly communicated with a transverse water inlet pipe at the bottom of the mold plate.
Preferably, the outer diameter of the plugging pipe is equal to the inner diameter of the transverse water pipe.
Compared with the prior art, the invention has the beneficial effects that: by installing the structures of the longitudinal water pipe, the transverse water pipe, the water inlet pipe, the helical blades, the blocking pipe and the like, firstly, softened cooling water is injected into the transverse water pipe through the water inlet pipe, the blocking pipe is arranged in the transverse water pipe, so that water flow can intensively flow into the longitudinal water pipe, the helical blades are arranged in the longitudinal water pipe, the cooling water can form two helical water flows under the action of the helical blades, the contact with the hole wall is strengthened, the cooling water can circulate along the transverse pipeline and the longitudinal pipeline, and when scale is formed, a mold plate can be detached to clean the scale on the blocking pipe. The device simple structure, the cooling effect is good, has improved the cooling efficiency in the mould production process, and the mould plate can be dismantled, clears up the residue and the incrustation scale of aquatic, is fit for market and promotes.
