Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
Examples
Referring to fig. 1 and fig. 2, the core-pulling locking mechanism for the sliding block of the dual-color injection mold of the embodiment includes a sliding block seat 2 arranged on a movable mold, a first shovel base 1 arranged on a fixed mold of a first injection mold and a second shovel base 6 arranged on a fixed mold of a second injection mold, the movable mold can perform position switching between the fixed mold of the first injection mold and the fixed mold of the second injection mold through rotary motion, mold opening is rotated by a certain angle after mold closing injection of the first injection mold, mold closing injection is performed again at the position of the second injection mold, and a dual-color injection molding process is completed. The shovel base I1 is matched with the inclined plane of the sliding block base 2 in a matched mode in a first injection mode, and the shovel base II 6 is matched with the inclined plane of the sliding block base 2 in a matched mode in a second injection mode, so that the position of the core-pulling sliding block is firm and stable when the die is matched. In order to prevent the slider seat 2 from not loosening after an injection mold is opened, a floating type stop block mechanism is designed at the bottom of the slider seat 2 in the embodiment, the floating type stop block mechanism specifically comprises a stop block 3, a spring 4 and a cushion block 5, the cushion block 5 is fixed on a movable mold, the stop block 3 is slidably mounted on the movable mold, and the spring 4 is arranged between the stop block 3 and the cushion block 5, so that the stop block 3 can elastically stretch and retract on the movable mold; the bottom of the slide block seat 2 is provided with a stop groove, the top of the stop block 3 is provided with a stop part matched with the stop groove, and the shovel base II 6 is provided with an extension part for pressing down the stop block 3 after the two-shot die assembly. When the injection mold is closed, the stop part of the stop block 3 is embedded into the stop groove of the slide block seat 2 to play a role in limiting; when the two-shot mold is closed, the extending part of the shovel base II 6 presses the block 3 downwards to enable the stop part of the block 3 to be separated from the stop groove of the slide block seat 2.
In order to improve the reliability of the stop mechanism, the stop block 3 is also provided with a step matched with the extension part of the second shovel base 6, and when the second injection mold is closed, the extension part of the second shovel base 6 can be abutted against the step of the stop block 3 to press down the stop block 3, so that the pressing down action of the stop block 3 is more accurate and smooth. In addition, the moving stroke of the stop block 3 pressed down by the second shovel base 6 is preferably greater than the height of the stop groove of the slider seat 2, so that the slider seat 2 can stably and quickly complete the core pulling action when the mold is opened by the second injection.
In order to understand better the technical scheme of the utility model, now combine figure 1 and figure 2 to explain the utility model discloses a double-shot injection mould slider locking mechanical system of loosing core's theory of operation.
As shown in fig. 1, when the double-color injection mold is injection-molded, the shovel base 1 is wedged with the slider seat 2 through the inclined surface, and the stopping part at the top of the stop block 3 is clamped into the stopping groove of the slider seat 2; after injection molding of the injection cavity is completed, the fixed die and the movable die are opened, and at the moment, the first shovel base 1 is separated from the wedging surface of the sliding block seat 2; then the movable mould rotates certain angle, for example 180 degrees, makes the movable mould reach two and injects the injection moulding position, and in the movable mould rotation process, dog 3 imbeds in the retaining groove of slider seat 2 all the time to can not make slider seat 2 take place to become flexible because of reasons such as self gravity. As shown in fig. 2, when the movable mold reaches the second-shot injection position for mold closing, the extension part of the second shovel base 6 protrudes out of the bottom of the slider seat 2, so that after the second-shot mold closing, the second shovel base 6 presses the stop block 3 down to separate the stop part of the stop block 3 from the stop groove of the slider seat 2, after the second-shot injection is completed, the movable mold and the fixed mold are opened again, and the core pulling mechanism simultaneously drives the slider seat 2 to perform core pulling during mold opening so that the stop groove of the slider seat 2 passes over the stop block 3 to complete core pulling.
The utility model discloses a double-shot injection mould slider locking mechanism of loosing core designs floating locking dog bottom the take-up housing, utilizes two to penetrate two and pushes down the dog in shovel base when the compound die, realizes two and penetrates behind the die sinking that the dog breaks away from mutually with the take-up housing and accomplishes the action of loosing core, and locking mechanism simple structure is compact, and is stable firm to the limiting displacement of take-up housing, makes the slider of loosing core fix a position accurate and difficult not hard up, has guaranteed the shaping quality of product, has improved the life of mould.
The present invention and its embodiments have been described above schematically, and the description is not intended to be limiting, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without creatively designing the similar structural modes and embodiments to the technical solutions, they should belong to the protection scope of the present invention.
