Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 to 6: a double-slider mechanism capable of realizing secondary core pulling comprises a base 1 arranged on a movable template, wherein the top end surface of the base 1 is an inclined surface, a slider seat 2 is connected on the inclined surface of the base 1 in a sliding manner, the double-slider mechanism also comprises a locking block 3 connected on a fixed template, an inclined guide post 4 is arranged on the locking block 3, the inclined guide post 4 is connected in an inclined guide groove arranged on the slider seat 2 in a sliding manner, a supporting block 5 positioned at the inclined lower part of the slider seat 2 is also arranged on the base 1, a sliding groove is arranged on the slider seat 2, the bottom surface of the sliding groove and the supporting block 5 jointly support a first slider 6 in a sliding manner, an installation seat 7 is arranged on the vertical surface of the sliding groove, a core 8 is connected in the installation seat 7, a first slider spring 9 is arranged at one end of the first slider 6 far away from a cavity, and the first slider spring 9 is positioned between the first slider 6 and the installation seat 7, the core-pulling-first 8 is movably connected in the first slide block 6, the end part of the core-pulling-first 8 can extend into the cavity and form a part of the cavity when the mold is closed,

The working process of the double-slider mechanism capable of realizing the secondary core pulling action of the embodiment of the utility model is as follows: as shown in fig. 2, in the mold clamping state, the front end of the core 8 is inserted into the cavity and forms a part of the cavity, at this time, the end of the second slide 12 is also located in the cavity and forms a part of the cavity, the molding machine injects the material in the molten state into the cavity through the material channel, the material fills the cavity and is cooled to form the product shown in fig. 1,

when the mold is opened, the locking block 3 moves upwards relative to the slider seat 2 under the driving of the movable mold plate, the inclined guide post 4 drives the slider seat 2 to move upwards along the inclined surface of the base 1 in the process that the locking block 3 moves upwards, and the first core 8 is driven by the movement of the slider seat 2 to be drawn out of the cavity due to the connection between the first core 8 and the slider seat 2 through the mounting seat 7, so that the first core drawing action (as shown in fig. 3) is realized; while the core 8 is drawn firstly, the first sliding block 6 at the outer side of the core 8 is continuously pressed outside the product under the action of the first sliding block spring 9, and the structure can ensure that the product cannot be displaced when the core 8 is drawn firstly; in the process, the limit barrier 10 moves along with the slider seat 2 and slides in the first limit groove 11;

as shown in fig. 4, the mold opening is continued, the slider seat 2 continues to move obliquely upward, at this time, the limiting barrier strip 10 has moved to the side wall of the first limiting groove 11, that is, the slider seat 2 starts to pull the first slider 6 to move upward through the limiting barrier strip 10, in this process, the core-pulling core 8 continues to be pulled out from the product, and the second slider 12 slidably connected to the first slider 6 is kept relatively fixed with the workpiece under the action of the second slider spring 15 until the limiting portion 13 at the bottom of the second slider 12 contacts with the side wall of the second limiting groove 14 on the first slider 6, at this time, the first slider 6 pulls the second slider 12 to move together, so that the core-pulling operation at the flanging position of the end of the second slider 12 and the product is realized;

when the mold is completely opened, the mold core 8 is firstly drawn out of the product, at the moment, the limiting groove arranged on the bottom end face of the slider seat 2 just moves to the spring top thread 16, and the spring top thread 16 is propped in the limiting groove, so that the slider seat 2 is prevented from sliding downwards along the inclined plane; in this state, all parts in the mechanism are separated from the projection profile of the cavity in the horizontal direction, and the ejection mechanism ejects the product from the cavity, so that the injection molding processing operation of the workpiece shown in fig. 1 is completed.
