Technical Field

[0001] This utility model relates to the field of extrusion molding die technology, and in particular to an extrusion molding die that is easy to release material. Background Technology

[0002] A mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being shaped. An extrusion molding mold is a mold installed on a stamping press during the extrusion process, used to force the blank through a mold cavity of a specific shape, thereby obtaining a product with the required cross-sectional shape and size.

[0003] Existing extrusion molding dies for sheet metal processing can be divided into fixed dies and moving dies. The moving die is installed on the stamping part of the press, while the fixed die is fixed in the appropriate position. Since the fixed die of the existing extrusion molding die does not have an ejector component, when the sheet metal is tightly connected to the cavity of the fixed die after extrusion molding, the operator cannot easily remove the metal part. If a tool is used to pry it, it may cause deformation of the metal part. Therefore, the fixed die of the existing extrusion molding die is inconvenient to use. To address this, we provide an extrusion molding die with easy material removal. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing extrusion molding dies where manual unloading is not possible, and to provide an extrusion molding die that allows for easy unloading.

[0021] 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.

[0022] Example 1

[0023] like Figures 1-3 As shown, this utility model provides a technical solution: an easy-to-demold extrusion molding die, comprising: a fixed mold 1, an ejector mechanism 2 inside the fixed mold 1, the ejector mechanism 2 including an ejector block 21, the ejector block 21 being sleeved inside the fixed mold 1, a movable rod 22 sleeved inside the fixed mold 1, the movable rod 22 being fixedly connected to the ejector block 21, a collar 23 sleeved on the outer surface of the movable rod 22, the collar 23 being fixedly connected to the movable rod 22, a spring 24 sleeved on the outer surface of the movable rod 22, and a semi-circular block 25 at one end of the movable rod 22, the semi-circular block 25 being connected to the movable rod. 22 Fixed connection, the interior of the fixed mold 1 is provided with an extrusion block 26, the extrusion block 26 is slidably connected to the fixed mold 1, the extrusion block 26 is provided with an inclined surface 27, one end of the extrusion block 26 is provided with a connecting rod 28, the connecting rod 28 is fixedly connected to the extrusion block 26, the interior of the fixed mold 1 is provided with a reset mechanism 3, the top block 21 is slidably connected to the fixed mold 1, the moving rod 22 is slidably connected to the fixed mold 1, the connecting rod 28 is sleeved inside the fixed mold 1, the connecting rod 28 is slidably connected to the fixed mold 1, one end of the connecting rod 28 is provided with a push plate 29, the push plate 29 is fixedly connected to the connecting rod 28.

[0024] In this embodiment, by setting the ejector mechanism 2, the metal parts stuck inside the fixed mold 1 can be squeezed, causing the metal parts to detach from the fixed mold 1. A spring 24 is set, and the spring 24 can generate elastic force after being compressed. Then, when the compression of the collar 23 on the spring 24 is removed, the elastic force of the spring 24 can reset the moving rod 22 and the ejector block 21, so that the ejector block 21 enters the interior of the fixed mold 1, thus not changing the shape of the cavity on the fixed mold 1. At the same time, the ejector block 21 can move along the inner wall of the cavity of the fixed mold 1, so that the ejected metal parts will not be deformed. In addition, a pressing block 26 is set, and the pressing block 26 can use its inclined surface 27 at the top to press the semi-circular block 25, so that the semi-circular block 25 can change the position of the moving rod 22 and the ejector block 21, thereby achieving the purpose of ejecting the metal parts.

[0025] Example 2

[0026] like Figures 1-3 As shown, the reset mechanism 3 includes a guide block 31, which is sleeved inside the fixed mold 1. The guide block 31 is slidably connected to the fixed mold 1 and is fixedly connected to the connecting rod 28. One end of the guide block 31 is provided with a limiting piece 32, which is fixedly connected to the guide block 31. One side of the limiting piece 32 is provided with a spring 33.

[0027] In this embodiment, by setting a reset mechanism 3, the extrusion block 26 and the connecting rod 28 are automatically reset after sliding, so as not to affect the processing personnel's subsequent pricing of the metal sheet. A guide block 31 is set, and the guide block 31 can guide the limiting piece 32, so that the limiting piece 32 can compress the second spring 33, so that the second spring 33 generates elastic force, and thus the elastic force of the second spring 33 can reset the extrusion block 26 and the connecting rod 28 and other components.

[0028] Working principle:

[0029] like Figures 1-3As shown, in use, the fixed mold 1 is fixedly installed, while the moving mold used in conjunction with it is installed on the stamping machine. When the moving mold and the fixed mold 1 are closed, the metal sheet can be extruded and formed. The formed metal part will be placed in the cavity of the fixed mold 1. If the metal part is in too close contact with the inner wall of the cavity and cannot be manually ejected, the push plate 29 can be pushed. At this time, the push plate 29 will drive the connecting rod 28 to slide, and the connecting rod 28 will drive the extrusion block 26 to slide simultaneously. At the same time, the connecting rod 28 will drive the guide block 31 and the limiting plate 32 to compress the spring 33, so that the spring 33 generates elastic force. The extrusion block 26 will cooperate with the inclined surface 27. The semicircular block 25 is pressed down, causing the semicircular block 25 to move the moving rod 22 upward. The collar 23, which is fixedly connected to the moving rod 22, compresses the spring 24, causing the spring 24 to generate elastic force. At the same time, the moving rod 22 moves the top block 21 upward, thereby pushing the metal part away from the fixed mold 1. When the push plate 29 is released, the elastic force of the second spring 33 is released instantly, and the pressing block 26 and connecting rod 28 are reset. At the same time, the elastic force of the first spring 24 is also released, and the moving rod 22 and the top block 21 are automatically reset, allowing the top block 21 to enter the interior of the fixed mold 1. Finally, the metal part can be removed.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
