Abstract
The invention provides a wire drawing solving method for a large water gap die, which relates to the technical field of dies and comprises a large water gap die body, wherein a large circular groove is formed in the top surface of the large water gap die body, a small circular groove is formed in the position, close to the edge, of the top surface of the large water gap die body, a squirt nozzle is formed in the bottom surface of the large circular groove, a wire drawing preventing groove is formed in the center of the squirt nozzle, the squirt nozzle is designed into a taper circle through innovative squirt nozzle design, the diameter of the tail end of the squirt nozzle is 8, the wire drawing preventing groove with the diameter of 1X1MM is additionally arranged in the middle of the mouth part of 3, after production is finished, wire drawing is carried out under the action of reverse tension formed by the wire drawing preventing groove, so that the problem of water gap wire drawing is solved, the quality of products is improved, the appearance defects of the products caused by the wire drawing at the water gap are reduced, the rejection rate of the products is increased due to the wire drawing at the water gap, the production efficiency is improved, and the die crush caused by the serious wire drawing at the water gap is avoided, reduce the mould risk of repairing, reduce the mould cost of repairing.
Description
Technical Field
The invention relates to the technical field of dies, in particular to a large water-mouth die solving a wire drawing method.
Background
The mold is called the master of the industry, and the production and development level of the mold is one of the important marks of the mechanical manufacturing level. With the rapid development of manufacturing industry, people have high pursuit on the quality, weight and appearance of products. The annual output of plastics is more than the sum of the annual outputs of steel and nonferrous metals before 10 years, and plastic products are widely applied to the national pillar industry of automobiles, electromechanics, instruments, aerospace, aviation and the like and various fields related to the daily life of people. The plastic product forming method has many times, and about more than half of the plastic products in the world are injection molds. The injection mold can produce products with high efficiency.
The injection mold comprises a large water gap mold, a thin water gap mold and a hot runner mold. Large gate molds are the most common injection molds. This patent is applied to big mouth of a river mould, but big mouth of a river mould leads to injection moulding product quality to descend because of mouth of a river wire drawing problem, and the rejection rate increases. The die can be crushed seriously, the product quality is improved, and the production efficiency is improved.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides a large water-jet mold for solving a wire drawing method.
In order to achieve the purpose, the invention adopts the following technical scheme: a method for solving wire drawing of a large nozzle mold comprises the large nozzle mold body, wherein a large circular groove is formed in the top surface of the large nozzle mold body, a small circular groove is formed in the position, close to the edge, of the top surface of the large nozzle mold body, a squirt nozzle is formed in the bottom surface of the large circular groove, and a wire drawing preventing groove is formed in the center of the squirt nozzle.
Preferably, the squirt mouth is communicated with the anti-wiredrawing groove, the squirt mouth is in a taper circle shape, and the anti-wiredrawing groove is in a rectangular shape.
Preferably, the shape of the large water-mouth mold body is circular.
Preferably, the large water mouth mold body is made of H steel.
Preferably, the shape of the large circular groove is circular.
Compared with the prior art, the invention has the advantages and positive effects that,
according to the invention, through the innovative sprue bushing design, the sprue bushing is designed into a taper circle, the diameter of the tail end is phi 8, the 1X1MM anti-wire drawing groove is added in the middle of the mouth part is phi 3, and after production is finished, wire drawing is cut off under the action of reverse tension formed by the anti-wire drawing groove, so that the problem of water gap wire drawing is solved, the product quality is improved, the product appearance defect caused by water gap wire drawing is reduced, the rejection rate of products caused by water gap wire drawing is reduced, the production efficiency is improved, the die crush caused by serious water gap wire drawing is avoided, the die repairing risk is reduced, and the die repairing cost is reduced.

FIG. 2 is a top view of a large water-jet mold according to the present invention for solving the wire drawing method.
Illustration of the drawings:
1. a large water port mold body; 2. a large circular groove; 3. a small circular groove; 4. a squirt nozzle; 5. prevent wire drawing groove.
Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.
The effect that the aforesaid reached does, through the design of innovation sprue bushing 4, the shape design becomes the tapering circle, the tip diameter is phi 8, the oral area is phi 3 middle increase 1X1MM prevent wire drawing groove 5, after the production is accomplished, prevent that wire drawing groove 5 forms the wire drawing under the effect of reverse tension, thereby solve mouth of a river wire drawing problem, improve the goods quality, it leads to product appearance defects to reduce because of the mouth of a river wire drawing, reduce the product and lead to the increase of rejection rate because of the mouth of a river wire drawing, thereby improve production efficiency, stop because mouth of a river wire drawing seriously leads to the mould to crush, reduce the mould repair risk, reduce the mould repair cost.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
