Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a variable mold for forging. Background Technology

[0002] A mold is a tool used to shape a blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. A mold has a specific contour or internal cavity shape. Using the contour shape with cutting edges allows the blank to be separated according to the contour line (blanking). Using the internal cavity shape allows the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die), which can be separated or combined.

[0003] When handling existing forging dies, the forgings often stick to the die body due to pressure, making them difficult to remove. Utility Model Content

[0004] To address the aforementioned technical problems, a variable die for forging is provided.

[0005] To achieve the above objectives, in a preferred embodiment of the present invention, the present invention includes a support plate, on which a molding die is formed by a plurality of movable blocks surrounding the support plate. The tops of the movable blocks are driven by a turntable. An ejection device is provided inside the molding die and is disposed on a base plate. The center of the support plate is connected to a telescopic rod.

[0006] In a preferred embodiment, the present invention may be further configured such that the molding die includes a movable block, the bottom of which is disposed on a disc of a support plate, and a convex shaft is disposed on the top of the movable block, the convex shaft cooperating with a groove on a turntable.

[0007] In a preferred embodiment, the present invention may be further configured such that each of the movable blocks has inwardly extending teeth on its top inner wall.

[0008] In a preferred embodiment, the present invention may be further configured such that the side wall of the turntable is connected to the telescopic end of the telescopic cylinder disposed on the support plate.

[0009] In a preferred embodiment, the present invention may be further configured such that the ejection device includes a shaft, one end of which is disposed on a base plate, and the other end is connected to an ejection body that surrounds the bottom of the cavity by a movable block.

[0010] In a preferred embodiment, the present invention may be further configured such that a spring is fitted on the shaft at a position between the base plate and the support plate.

[0011] Beneficial effects: The present invention provides a variable mold for forging, in which the movable block can be changed according to different forgings and replaced with a suitable one. After the forging is formed, it does not need to be manually removed and can be directly ejected by the ejection device. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown, a variable mold for forging includes a support plate 2. A forming mold is formed by a plurality of movable blocks 5 surrounding the support plate 2. The top of the movable blocks 5 is driven by a turntable 4. An ejection device is provided inside the forming mold and is located on a base plate 1. The center of the support plate 2 is connected to a telescopic rod 8. In use, the forging to be formed is placed into the cavity formed by the movable blocks 5. The telescopic cylinder 3 drives the turntable 4 to rotate, and the turntable 4 drives the movable blocks 5 to move inward and squeeze.

[0020] The molding die includes a movable block 5, the bottom of which is disposed on the disc of the support plate 2, and a convex shaft is disposed on the top of the movable block 5, which cooperates with the groove on the turntable 4.

[0021] The top inner wall of each movable block 5 is provided with inwardly extending teeth.

[0022] The side wall of the turntable 4 is connected to the telescopic end of the telescopic cylinder 3, which is set on the support plate 2.

[0023] The ejection device includes a shaft 7, one end of which is disposed on the base plate 1, and the other end is connected to the ejection body of the movable block 5 surrounding the bottom of the cavity.

[0024] A spring 6 is fitted on the shaft 7 at a position between the base plate 1 and the bearing plate 2.

[0025] It should be noted that in this article, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.
