Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 3, a mold ejection structure may include a slide 1, a slide insert 2, a slide seat 3, a slide scoop base 4, and an ejection cylinder 5. The slider 1 is slidably engaged on the slider holder 3. Specifically, the slider holder 3 is provided with a sliding groove 31, and the slider 1 is provided with a protruding strip 11, wherein the protruding strip 11 is slidably engaged in the sliding groove 31. The slider seat 3 is arranged on the lower template 10 in a lifting way. The slide insert 2 is fixedly mounted (e.g. by means of corresponding screws) on the side (left side in fig. 1) of the slide 1. The shoe scoop base 4 is fixedly mounted on an upper die plate (not shown) and abuts against an opposite side surface (right side surface in fig. 1) of the shoe 1. The contact surface between the slide block shovel base 4 and the slide block 1 is an inclined surface. Through the up-and-down motion of the slide block shovel base 4, the slide block 1 slides left and right on the slide block seat 3, and then the slide block insert 2 is driven to move left and right, and the core inserting and core pulling actions are realized. The ejection cylinder 5 is fixedly mounted below the slider holder 3 (e.g., fixedly mounted on the base plate 20 by screws) and is drivingly connected to the slider holder 3. Therefore, the ejector cylinder 5 is operated to eject the slide holder 3 together with the molded product 100 and then remove the molded product 100 from the slide insert 2 by the robot, so that the appearance of the molded product 100 is not damaged.

To prevent the slide 1 from slipping out of the slide holder 3 when the mold is opened, a stop block 6 is fixed to the slide holder 3 (e.g., by means of a corresponding screw). The limiting block 6 is located on the right side of the sliding block shovel base 4, namely the sliding block shovel base 4 is located between the limiting block 6 and the sliding block 1. When the slide block shovel base 4 moves upwards under the driving of the upper template, the slide block 1 moves rightwards along the slide block seat 3 and stops after touching the limiting block 6.

In this embodiment, the piston rod 51 of the ejection cylinder 5 is fixedly connected to the slider holder 3 through a sleeve 7. Specifically, the piston rod 51 is provided at an upper end thereof with an external thread, the sleeve 7 is closed at an upper end thereof and provided with a first screw hole 71, the sleeve 7 is provided with an internal thread engaged with the external thread of the piston rod 51, the slider housing 3 is provided with a mounting hole 32, and the sleeve 7 is fixed to the bottom surface of the slider housing 3 by a screw (not shown) passing through the mounting hole 32 and being screwed into the first screw hole 71. During installation, the ejection cylinder 5 is firstly fixed on the bottom plate 20, then the sleeve 7 is screwed on the piston rod 51 of the ejection cylinder 5, and finally the sleeve 7 and the slider seat 3 are fixed together through screws.

Preferably, the end of the piston rod 51 is provided with a second screw hole 511, and a screw can be screwed into the second screw hole 511 through the first screw hole 71, so that the connection between the slider holder 3 and the piston rod 51 of the ejection cylinder 5 is more reliable.

Preferably, the ejection cylinder 5 is a square cylinder to facilitate mold design and installation.

The following is a brief explanation the utility model discloses a working process, when the die sinking, at first the slider mold insert on the left side accomplishes through corresponding mechanism 30 of loosing core and looses core, and slider 1 moves right under the effect of slider shovel base 4 simultaneously, realizes that the part is loosed core, then ejection cylinder 5 moves, and is ejecting together with take-up housing 3 with shaping product 100, takes off shaping product 100 from slider mold insert 2 through the manipulator at last. The molded product 100 is not in contact with other mold components throughout the ejection process, thereby ensuring an intact appearance.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
