Description

Technical Field

[0001] This utility model belongs to the field of extrusion mold technology, and in particular relates to a radial plate structure for an extrusion mold head. Background Technology

[0002] Currently, for the radiation plate of large cavity extrusion molds, an integral plate (as shown in the attached image) is used. Figure 6-9 As shown in the image, the cavity shape shown in this plate is processed using wire cutting. This irregular cutting method has the following disadvantages:

[0003] 1. Imports (as per attached) Figure 8 ) and exports (as attached) Figure 7 The large shape difference leads to a large processing angle. During the wire cutting process, the copper wire discharge can damage the lead tip, thus affecting the life of the equipment.

[0004] 2. The swing distance of the upper and lower head of a conventional slow wire EDM machine is 100 mm. If the difference between the inlet and outlet cavities exceeds this size, the cavity will be unable to be processed.

[0005] 3. From the appendix Figure 9 It can be seen that the shapes of the inlet and outlet are too different, which will cause the unloaded material to be unable to be removed;

[0006] Therefore, this utility model proposes a radial plate structure for the extrusion die head to solve the above problems. Utility Model Content

[0007] This invention provides a radial plate structure for an extrusion die head, which aims to solve the problems mentioned in the background art.

[0008] This utility model is implemented as follows: a radial plate structure for an extrusion die head, wherein the radial plate includes a radial plate and a radial plate bottom;

[0009] The connecting surface between the upper and lower radiant plates after mold assembly is the parting surface. The bottom surface of the radiant plate is milled to form an upper cavity, and the top surface of the lower radiant plate is milled to form a lower cavity. The upper and lower cavities are molded together to form a cavity. An inlet is provided on one side of the cavity, and an outlet is provided on the other side of the cavity.

[0010] Preferably, the inlet and the outlet are distributed opposite to each other on the front and rear sides of the radiating plate.

[0011] Preferably, the parting surface divides the radiant plate into an upper radiant plate and a lower radiant plate by wire cutting.

[0012] Preferably, the upper cavity and the lower cavity are matched after mold closing.

[0013] Preferably, the inlet is used for the profile to enter the cavity.

[0014] Preferably, the outlet is used to remove the unloaded material.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The large-cavity extrusion die's radiant plate is made of a single piece. A parting surface is added to this single piece, which is formed by wire cutting. The parting surface divides the radiant plate into an upper radiant plate and a lower radiant plate, exposing the cavities that need to be machined. The required cavities are then machined using a machining center. Specifically, an upper cavity is milled on the bottom surface of the radiant plate, and a lower cavity is milled on the top surface of the lower radiant plate. The upper and lower cavities are matched, and when they are closed, they form the cavity. One side of the cavity has an inlet, and the other side has an outlet. This not only saves machining time but also reduces the difficulty of machining. Attached Figure Description

[0033] Example:

[0034] Please see Figure 1-5 This utility model provides a technical solution: a radial plate structure for an extrusion die head, the radial plate including a radial plate 1 and a radial plate 2; the connecting surface of the radial plate 1 and the radial plate 2 after mold closing is a parting surface 5, the bottom surface of the radial plate 1 is milled to form an upper cavity 6, the top surface of the radial plate 2 is milled to form a lower cavity 7, the upper cavity 6 and the lower cavity 7 are closed to form a cavity, an inlet 3 is provided on one side of the cavity, and an outlet 4 is provided on the other side of the cavity.

[0035] For further details, please refer to Figure 3 and Figure 4Import 3 and export 4 are distributed on the front and back sides of the radiating plate.

[0036] For further details, please refer to Figure 2 The parting surface 5 divides the radiant plate into upper radiant plate 1 and lower radiant plate 2 by wire cutting.

[0037] In this embodiment, the large-cavity extrusion die radiant plate is a single piece, with a parting surface 5 added to the single piece. The parting surface 5 is formed by dividing the single piece into two parts: an upper radiant plate 1 and a lower radiant plate 2 (e.g., ...). Figure 2 As shown in the figure, the cavity that needs to be processed is exposed. At this time, the required cavity is milled by machining center. Specifically, an upper cavity 6 is milled on the bottom surface of the radiant plate 1, and a lower cavity 7 is milled on the top surface of the lower radiant plate 2. The upper cavity 6 and the lower cavity 7 are matched. When the upper cavity 6 and the lower cavity 7 are molded together, the cavity is formed. An inlet 3 is opened on one side of the cavity, and an outlet 4 is opened on the other side of the cavity. This not only saves processing time, but also reduces the processing difficulty.

[0038] Comparative example:

[0039] Please see Figure 6-9 The radiation plate of the large cavity extrusion die is made of a single piece (such as...). Figure 6 As shown in the image, the cavity shape shown in this integral plate is machined using wire cutting. The cavity is machined by hollowing out the interior of the plate using wire cutting, which is a difficult process and also has the following disadvantages: First, the import (as shown in the attached image)... Figure 8 ) and exports (as attached) Figure 7 (1) Significant shape differences result in large machining angles, which can damage the lead tip during wire EDM due to copper wire discharge, thus affecting the equipment's lifespan; (2) The vertical head swing distance of a typical slow wire EDM machine is 100 mm. If the difference between the inlet and outlet cavities exceeds this dimension, the cavity will be unprocessable; (3) Due to the attached... Figure 9 It can be seen that the shapes of the imported and exported materials are too different, which makes it impossible to remove the unloaded material.

[0040] Comparison between the examples and comparative examples:

[0041] The comparative example involves hollowing out the plate using wire cutting, which is more difficult to process.

[0042] This structure divides the overall plate into a parting surface, and then the upper and lower parts of the parting surface are milled. After that, the upper and lower cavities are closed. This machining process reduces the machining difficulty of the cavity.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
