The utility model is simple in structure and convenient to use, and the glue inlet is a whole, which ensures that the temperature at the glue inlet is consistent during molding, and prevents appearance problems such as bulges or depressions. Injection pressure during product molding to avoid gate marks on one side of the product due to glue feeding.
Description
Technical Field
The utility model relates to an injection mold technical field, concretely relates to flip-chip mould advance gluey mechanism.
Background
With the development of the mobile phone industry, mobile phone products become thinner and thinner, and the requirement of part of thin-wall products is difficult to meet by the common mold structure nowadays. For thin-walled products, such as mobile phone battery covers, in order to avoid influencing the appearance of the products, the glue inlet of the mold with a common structure is composed of a plurality of parts, temperature differences exist among the parts, the thermoplastic material is sensitive to the temperature, and when the products are molded, the appearance problems such as bulges or depressions are caused by overlarge temperature differences.
Disclosure of Invention
To the defect of above-mentioned prior art, the utility model provides a flip-chip mould advance gluey mechanism, simple structure, convenient to use advance jiao kou and be a whole, when guaranteeing the shaping, advance the temperature unanimity of jiao kou department, prevent appearance problems such as arch or sunken, advance gluey through adopting thin water gap, injection pressure when effectively reducing the product shaping avoids the product simultaneously because of advancing gluey production runner vestige.
In order to achieve the above object, the utility model adopts the following technical scheme:
flip-chip mould advance gluey mechanism, including front mould benevolence and back mould, be equipped with runner plate mold insert on the back mould, be equipped with into jiao kou on the runner plate mold insert, the one side of advancing jiao kou is equipped with rather than the entering gluey runner of intercommunication, be equipped with thin mouth of a river runner in front mould benevolence and the back mould, the one end and the entering jiao kou intercommunication of thin mouth of a river runner, the opposite side of thin mouth of a river runner is equipped with thin mouth of a river and glues mouthful, the lower extreme of front mould benevolence is equipped with the position of moulding plastics that is used for placing the product, thin mouth of a river glues the.
In the above description, it is preferable that the rear mold is provided with a mounting groove for mounting the runner plate insert, and the runner plate insert is detachably mounted to the rear mold by a screw.
The utility model discloses produced beneficial effect is: the rear die is provided with a runner plate insert which is provided with a glue inlet, one side of the glue inlet is provided with a glue inlet runner communicated with the glue inlet, and the glue inlet is an integral body, so that the temperature at the glue inlet is ensured to be consistent during molding, and appearance problems such as protrusion or depression are prevented; one end of the thin water gap flow channel is communicated with the glue inlet, the other side of the thin water gap flow channel is provided with the thin water gap glue inlet, and the thin water gap glue inlet is adopted, so that the injection molding pressure during product molding can be effectively reduced, and the phenomenon that one side of a product is subjected to pouring gate marks due to glue inlet is avoided.
