Description

Technical Field

[0001] This utility model relates to the field of mold forming technology, specifically to a processing mold for a wire fixing cover. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. The main function of the wire fixing cover is to protect and fix the wire, preventing it from loosening, wearing, or shifting, while improving the cleanliness and safety of the equipment. The wire fixing cover includes a first connecting piece, a second connecting piece, and a connecting rod set between the two. The connecting rod, the first connecting piece, and the second connecting piece are integrally molded. In the existing technology, during the mold forming process, because the cross-sectional area of ​​the connecting rod is relatively small, it is easy to break or fail to form during the molding process, resulting in an increase in the scrap rate. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art where the connecting rod is relatively thin in cross-sectional area, making it easy to break or fail to form during the molding process, resulting in an increased scrap rate, thereby providing a processing mold for the fixed wire cover that can effectively improve the forming rate of the connecting rod.

[0004] Therefore, this utility model provides a processing mold for a wire fixing cover. The wire fixing cover includes a first connecting piece, a second connecting piece, and a connecting rod disposed between the two. The mold includes a lower mold and an upper mold disposed above the lower mold. A cavity for forming the wire fixing cover is provided between the upper mold and the lower mold. An injection molding device is provided at the upper mold. The injection molding device includes a first injection pipe disposed on one of the first connecting piece or the second connecting piece and a second injection pipe disposed on the other. The first injection pipe is disposed on the first connecting piece or the second connecting piece near the connecting rod, and the second injection pipe is disposed on the other side away from the connecting rod.

[0005] Furthermore: the first injection pipe is disposed on the first connecting piece, and the second injection pipe is disposed on the second connecting piece.

[0006] Furthermore: a forming plate is provided between the upper mold and the lower mold, the cavity is opened in the forming plate, and a number of push rods for ejecting the formed material are inserted in the forming plate.

[0007] Furthermore: a movable plate is provided on the side of the lower mold facing away from the upper mold, and the ejector rod is fixed on the movable plate. The movable plate can push the ejector rod to move towards the side closer to the lower mold.

[0008] Furthermore, a positioning rod is provided between the movable plate and the lower mold, and a return spring is sleeved on the positioning rod.

[0009] Furthermore, a push block is fitted onto one end of the top rod facing away from the moving plate.

[0010] Furthermore, the pusher is made of rubber material.

[0011] The technical solution of this utility model has the following advantages: 1. This utility model provides a processing mold for a wire fixing cover. A first injection pipe and a second injection pipe are respectively positioned near and away from the connecting rod. For example, if the second injection pipe is positioned near the connecting rod, then the first injection pipe is positioned away from the connecting rod. During injection molding, the material in the second injection pipe flows simultaneously to the connecting rod and the second connecting piece, while the material in the first injection pipe moves towards the position near the connecting rod. The materials from both pipes converge at the first connecting piece, ensuring that the material completely fills the connecting rod before solidification. This prevents the material from solidifying while flowing through the connecting rod, thus avoiding incomplete filling and failure of the wire fixing cover molding, effectively reducing the scrap rate.

[0012] 2. The present invention provides a processing mold for a wire fixing cover. A forming plate is embedded in the lower mold. A cavity for assisting in the forming of the wire fixing cover is set on the lower mold. After the upper mold and the lower mold are closed, the first injection pipe and the second injection pipe start to inject material to fill the cavity. After the material in the cavity is formed, the upper mold moves upward and the ejector rod pushes the formed material out of the cavity, thereby successfully completing the demolding.

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example This embodiment provides a processing mold for a wire fixing cover. The wire fixing cover includes a first connecting piece 1, a second connecting piece 11, and a connecting rod 12 disposed between the two. The mold includes a lower mold 2 and an upper mold 3 disposed above the lower mold 2. A cavity 4 for forming the wire fixing cover is disposed between the upper mold 3 and the lower mold 2. An injection molding device 5 is disposed at the upper mold 3. The injection molding device 5 includes a first injection pipe 51 disposed on one of the first connecting piece 1 or the second connecting piece 11 and a second injection pipe 52 disposed on the other. The first injection pipe 51 is disposed on the first connecting piece 1 or the second connecting piece 11 near the connecting rod 12, and the second injection pipe 52 is disposed on the other away from the connecting rod 12.

[0021] The specific improvements mentioned above are as follows: Figures 1-2 As shown, compared to the prior art, the first injection pipe 51 and the second injection pipe 52 are respectively located near the connecting rod 12 and away from the connecting rod 12. For example, if the second injection pipe 52 is located near the connecting rod 12, then the first injection pipe 51 is located away from the connecting rod 12. In this way, during injection, the material in the second injection pipe 52 can flow to the connecting rod 12 and the second connecting piece 11 simultaneously, while the material in the first injection pipe 51 moves towards the position near the connecting rod 12. The materials of both will converge at the first connecting piece 11. This ensures that the material can completely fill the connecting rod 12 before solidification, preventing the material from solidifying when it flows through the connecting rod 12, which would result in the material not being able to completely fill the connecting rod 12 and causing the entire wire cover to fail to form, thus effectively reducing the scrap rate.

[0022] Based on the above embodiments: the first injection pipe 51 is disposed on the first connecting piece 1, and the second injection pipe 52 is disposed on the second connecting piece 11.

[0023] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, the first injection pipe 51 is disposed on the first connecting piece 1, and the second injection pipe 52 is disposed on the second connecting piece 11. The positions of the first injection pipe 51 and the second injection pipe 52 can also be interchanged.

[0024] Based on the above embodiments: a forming plate 6 is provided between the upper mold 3 and the lower mold 2, the cavity 4 is opened in the forming plate 6, and a plurality of push rods 7 are inserted in the forming plate 6 for ejecting the material after forming.

[0025] The specific improvements mentioned above are as follows: Figure 3 and Figure 4As shown, the lower mold 2 is embedded with a molding plate 6, and the cavity 4 for assisting in the forming of the fixing cover is set on the lower mold 2. After the upper mold 3 and the lower mold 2 are closed, the first injection pipe 51 and the second injection pipe 52 start to inject material to fill the cavity 4. After the material in the cavity 4 is formed, the upper mold 3 moves upward, and the ejector rod 7 pushes the formed material out of the cavity 4, thus successfully completing the demolding.

[0026] Based on the above embodiments: a movable plate 8 is provided on the side of the lower mold 2 facing away from the upper mold 3, and the ejector rod 7 is fixed on the movable plate 8. The movable plate 8 can push the ejector rod 7 to move towards the side closer to the lower mold 2.

[0027] Based on the above embodiments: a positioning rod 9 is provided between the moving plate 8 and the lower mold 2, and a return spring is sleeved on the positioning rod 9.

[0028] The specific improvements mentioned above are as follows: Figure 1 As shown, a positioning rod 9 is provided at the upper end of the moving rod, and a space for the positioning rod 9 to be inserted is provided in the lower mold 2. When the material needs to be demolded, a driving device below the moving plate 8 will drive the moving plate 8 to move towards the side closer to the lower mold 2. Since the ejector rod 7 is fixed on the moving plate 8, when the moving plate 8 moves upward, the ejector rod 7 will also move upward, thereby pushing the molded material out of the cavity 4 and completing the demolding. When the material has been demolded, the moving plate 8 will drive the return spring to compress during its upward movement, thereby accumulating elastic potential energy in the return spring. When the moving plate 8 loses the force of the driving device, the return spring releases the elastic potential energy, which can drive the ejector rod 7 and the moving plate 8 back to the initial position.

[0029] Based on the above embodiments: a push block 92 is sleeved on one end of the top rod 7 facing away from the moving plate 8.

[0030] Based on the above embodiments: the pusher block 92 is made of rubber material.

[0031] The specific improvement is as follows: In order to prevent the ejector rod 7 from damaging the material when it pushes out the formed material, a pusher block 92 made of rubber material is provided on the side of the ejector rod 7 facing away from the moving plate 8. The pusher block 92 is sleeved on the upper end of the ejector rod 7 and can effectively protect the material when it is pushed out.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
