Description
Technical Field
The utility model relates to an injection mold technical field especially relates to mould plastics with interior movable mold insert.
Background
The mold internal cutting is the mold injection molding automation technology that the sprue is cut or extruded off before the plastic mold is opened, so that the separation of the parts and the materials is realized after the plastic mold is opened. The application of the in-mold cutting technology is suitable for various types of glue inlet gates such as a front film bottom-built gate, a back film side-glue inlet gate, a thimble glue inlet gate, a horn glue inlet gate, a disc gate and the like; in addition, the technology can also realize in-mold forming, such as: after glue injection, the mold is opened, a front hole, a local part is thinned and thickened and the like, and the slide block is driven to loose the core, so that the structure of the mold is simplified, and the size of the structure of the mold is reduced
Of course, in-mold cutting has inevitable disadvantages: the balance point of the injection pressure and the cutting force is difficult to master; the cutting effect is good only for PP/PE materials, and the raw materials are selective; burrs and the like are easily generated.
SUMMERY OF THE UTILITY MODEL
The application provides an injection molding is with interior movable mold insert, and the drawing of core drawing of patterns fast improves quantization production efficiency, in order to realize above-mentioned purpose, adopts following technical scheme: the method comprises the following steps: the micro cylinder 2, the micro cylinder pressure plate 3, the return spring 4 and the insert 6, wherein an oil cylinder is arranged in the micro cylinder 2 and is connected with an oil way; a micro cylinder pressure plate 3 is arranged below the micro cylinder 2; a return spring 4 is arranged inside the micro cylinder pressing plate 3, an insert 6 is connected below the micro cylinder pressing plate 3, and the bottom of the insert 6 is a product.
Preferably, a groove is provided below the micro-cylinder platen 3, and the top of the insert 6 is inserted into the groove.
Preferably, the top of the insert 6 is a semi-cylindrical shape and is inserted into the groove.
Preferably, an inwards concave limiting groove is arranged at the groove wall of the groove, the limiting groove corresponds to the semi-cylindrical arc section at the top of the insert 6, and the arc section is embedded in the limiting groove.
Preferably, the return springs 4 are arranged in pairs and symmetrically distributed on the left side and the right side of the groove.
Preferably, an insert protective sleeve 5 is nested outside the insert 6.
When the mold is closed and filled, the insert 6 enters the product for a certain distance in a state; when filling is finished and pressure maintaining is carried out, the insert 6 slowly retracts from the product, only one shallow thimble mark is arranged on the shape of the final product, a deep hole of the product cannot be caused, and shaking of the product during filling is avoided.
The utility model has the advantages that: when filling, a micro cylinder is used for applying force to a micro cylinder pressing plate, and the micro cylinder pressing plate drives the insert to press downwards to enter a product, so that the product is prevented from shaking up and down during injection molding; after filling, miniature jar clamp plate is replied under return spring's effect, and the mold insert is returned from the product, this patent application simple structure, convenient operation.
