Description
Technical Field
The utility model relates to an injection mold field especially relates to a take out mechanism in double-color mold.
Background
The double-color mold is a mold in which two plastic materials are injected on the same injection molding machine and are molded twice, but the product is only demoulded once. Usually accomplished with a set of molds and requires a specialized two-color injection molding machine. The two-color mold is increasingly popular in the market, and the appearance of the product can be more beautiful due to the process, and the color can be easily changed without adopting a spraying mode. In the existing process flow, after the injection molding of a first material is finished, a first fixed die and a movable die are opened under the tension of an injection molding machine, the movable die drives a first product to rotate 180 degrees, the movable die is not ejected at the moment, then the die is closed, the injection molding of a second material is carried out, after heat preservation and cooling, a second fixed die and the movable die are opened, a second product on the side of the movable die is ejected, and then the next production cycle is started. The current way is to combine inductive switch with the hydro-cylinder to control above-mentioned process, leads to the mould structure complicated, needs more auxiliary part and supporting part, still needs to set up more connection transition part, not only causes the loaded down with trivial details complicacy of processes such as installation, debugging, production, maintenance to in the rotatory in-process of mould, the response line of hydro-cylinder, oil pipe, water pipe can follow the mould and rotate together, very easily takes place to damage at the pivoted in-process, probably causes the moulding-die, produces huge economic loss.
In order to solve the technical problem, a patent with application number CN201620903867.2 proposes a two-color molding sliding block core-pulling mechanism, which is characterized in that: the device comprises a first inclined guide block, a second inclined guide block and a sliding block assembly; the upper end of the first inclined guide block is fixed on a first fixed die of the die, and the lower end of the first inclined guide block is provided with a first guide inclined plane; the upper end of the second inclined guide block is fixed on a second fixed die of the die, the lower end of the second inclined guide block is provided with a second guide inclined plane, and guide strips are protruded outwards from two sides of the second guide inclined plane; the slider component comprises a slider body and a locking block, a guide groove is formed in the vertical direction of the slider body, a first oblique guide block and a second oblique guide block can penetrate through the guide groove respectively and can move up and down in the guide groove, locking block mounting seats are arranged on two sides of the slider body respectively, the locking block is arranged in the locking block mounting seats and extends out of the guide groove, and the locking block compresses the first oblique guide block and the second oblique guide block, so that the structure has the following problems: when the oblique guide pillar of second inserted the guide slot, can receive blockking of latch segment, need make the latch segment withdraw through compression spring, the guide slot just can be inserted smoothly to the oblique guide pillar, but spring compression direction becomes 90 with the atress direction of latch segment, even make the atress terminal surface of latch segment inclined plane, also has the dead risk of card, causes production trouble.
