Switching structure of die for machining part with side turnup edges on periphery of top cover skylight

Abstract

The utility model discloses a switching structure of a die for machining a part with side turnup edges on the periphery of a top cover skylight. The switching structure comprises a switching driving plate, a transverse moving driving air cylinder, a switching wedge driving seat and a top cover skylight material pressing core which are sequentially arranged from top to bottom. The transverse movement driving air cylinder is connected with the upper die and used for limiting the switching wedge driving base, and a piston rod of the transverse movement driving air cylinder is connected with the switching driving plate and can drive the switching driving plate to move transversely. The four corners of the switching wedge driving base are connected with the large material pressing core through first nitrogen cylinders. And the lower end of the switching wedge driving seat is connected with a top cover skylight pressing core through a plurality of second nitrogen cylinders. By controlling the top cover skylight material pressing core to move in the large material pressing core, the top cover skylight pressure core is controlled to play a role when the top cover skylight needs to be turned over laterally, and the top cover skylight pressure core is controlled not to play a role when the top cover skylight does not need to be turned over laterally, qualified workpieces can be produced by using fewer molds, and the production cost is reduced.

[0005] A switching structure for a mold for processing a top cover skylight with side flanging parts on all sides, comprising a switching drive plate, a lateral drive cylinder, a switching wedge drive seat and a top cover skylight pressing core arranged in sequence from top to bottom;

[0006] The lateral drive cylinder is connected to the upper die, and is used to limit the switching wedge drive seat. The piston rod of the lateral drive cylinder is connected to the switching drive plate, and can drive the switching drive plate to move horizontally.

[0007] The four corners of the switching wedge drive seat are connected to the large pressing core through the first nitrogen cylinder;

[0008] The lower end of the switching wedge driving seat is connected to the top cover skylight pressing core through a plurality of second nitrogen cylinders.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The present application provides a set of molds that can meet the needs of two different parts. By controlling the top cover skylight pressure core to move inside the large pressure core, when the top cover skylight needs to be flipped over, the top cover skylight pressure core is controlled to function. When the top cover skylight does not need to be flipped over, the top cover skylight pressure core is controlled not to function. Fewer molds can be used to produce qualified parts, thereby reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0023] like Figure 1-Figure 6 The structure shown is an example embodiment provided by the present application.

[0024] The present embodiment provides a switching structure for a mold for processing a top cover skylight with side flanging parts on all sides, comprising a switching drive plate 1, a lateral drive cylinder 2, a switching wedge drive seat 5 and a top cover skylight pressing core 6 which are arranged in sequence from top to bottom;

[0025] The lateral drive cylinder 2 is connected to the upper die, and is used to limit the switching wedge drive seat 5. The piston rod of the lateral drive cylinder 2 is connected to the switching drive plate 1, and can drive the switching drive plate 1 to move horizontally.

[0026] The four corners of the switching wedge drive seat 5 are connected to the large pressing core 9 through the first nitrogen cylinder 4;

[0027] The lower end of the switching wedge driving seat 5 is connected to the top cover skylight pressing core 6 through a plurality of second nitrogen cylinders 7 .

[0028] It should be noted that the upper die pressing core switching scheme of the present application adopts an auxiliary pressing core design, and the rollover area pressing material is independently mounted as a top cover skylight pressing material core on the switching wedge drive seat. When the part does not need the skylight to flip over, the switching drive plate is moved a preset distance by the lateral drive cylinder, and the switching wedge drive seat and the top cover skylight pressing material core can be retracted to below the large pressing material core 9 mold surface through the first nitrogen cylinders at the four corners of the switching wedge drive seat. When the part needs the skylight to flip over, the upper die seat is closed to cause the first nitrogen cylinders at the four corners of the switching wedge drive seat to be compressed. At this time, the switching wedge drive seat and the top cover skylight pressing material core protrude from the large pressing material core 9, and complete the flipping work content with the rollover mechanism of the lower die.

[0029] In addition, it should be noted that both the first nitrogen cylinder and the second nitrogen cylinder can be retracted, thereby increasing the retraction stroke.

[0030] Preferably, a plurality of guide sleeves 8 are provided on the switching wedge drive seat 5, and a plurality of guide rods 3 are provided on the upper die, and each guide rod 3 is respectively inserted into a guide sleeve 8 at a corresponding position and slidably connected.

[0031] Preferably, a plurality of second nitrogen cylinders 7 are arranged along the upper edge of the top cover skylight pressing core 6 .

[0032] Finally, it should be noted that the above embodiments are only used to illustrate and explain the present invention, and are not intended to limit the present invention to the scope of the described embodiments. In addition, those skilled in the art can understand that the present invention is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present invention, and these variations and modifications all fall within the scope of protection claimed by the present invention.
