Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe manufacturing technology, and in particular to a carbon fiber exhaust pipe manufacturing mold. Background Technology

[0002] The exhaust pipe of a car is installed in the exhaust pipe between the engine exhaust manifold and the muffler, making the entire exhaust system flexibly connected. This helps to reduce vibration and noise, facilitate installation, and extend the life of the exhaust muffler system. In the process of manufacturing the car exhaust pipe, molds are often used to shape the exhaust pipe.

[0003] Currently, when molding exhaust pipes, workers often need to activate the ejector mechanism separately to eject the molded exhaust pipe after the mold is closed. This process is cumbersome and affects manufacturing efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a carbon fiber exhaust pipe manufacturing mold, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A carbon fiber exhaust pipe manufacturing mold includes a lower mold and an upper mold. Limiting posts are inserted at the four corners of the lower mold. The bottom end of the limiting post is fixedly connected to the upper surface of the top plate frame. A top post is fixedly connected to the middle of the upper surface of the top plate frame. The top post is connected to the lower mold by a compression spring. Limiting holes are opened at the four corners of the lower surface of the upper mold.

[0007] Preferably, both sides of the upper mold are fixedly connected to limit rings, and a column is inserted into the inside of the limit ring.

[0008] Preferably, a baffle is fixedly connected to the top of the column, and the bottom of the column is fixedly connected to the upper surface of the support plate.

[0009] Preferably, the support plate is fixedly installed on the side of the lower mold, and the limiting ring is connected to the support plate by a support spring.

[0010] Preferably, an electric push rod is fixedly connected to the upper surface of the upper mold, and the electric push rod is fixedly installed on the inner top wall of the fixed frame.

[0011] Preferably, both ends of the fixed frame are fixedly connected to the upper surface of the base plate, and a support rod is fixedly connected to the upper surface of the base plate, with the top end of the support rod fixedly connected to the lower surface of the lower mold.

[0012] Preferably, the inner diameter of the limiting hole is larger than the outer diameter of the top post.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This carbon fiber exhaust pipe manufacturing mold, through the coordinated arrangement of a lower mold, an upper mold, a limiting post, a top plate frame, a top post, and a compression spring, allows for immediate and intuitive identification of the correspondence between the upper and lower molds as the upper mold moves downward. As the upper mold continues to move downward, pressure is applied to the limiting post, deforming the compression spring. The top plate frame then moves the top post downward, allowing the exhaust pipe casting liquid to be poured into the mold. After molding, the operator simply activates an electric push rod, which moves the upper mold upward, separating it from the lower mold. As the upper mold moves upward, the limiting post loses pressure, allowing the compression spring to reset, which in turn moves the top plate frame upward. The top post then lifts the molded product upward, facilitating demolding without requiring the operator to press other mechanisms, thus significantly improving manufacturing efficiency.

[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 Figure 1-5 As shown, a carbon fiber exhaust pipe manufacturing mold includes a lower mold 1 and an upper mold 2. Limiting posts 3 are inserted at the four corners of the lower mold 1. The bottom end of the limiting posts 3 is fixedly connected to the upper surface of the top plate frame 4. The middle part of the upper surface of the top plate frame 4 is fixedly connected to the top post 5. The top post 5 is connected to the lower mold 1 by a compression spring 6. Limiting holes 7 are opened at the four corners of the lower surface of the upper mold 2.

[0024] In practical use, through the coordinated arrangement of the lower mold 1, upper mold 2, limiting post 3, top plate frame 4, top post 5, and compression spring 6, as the upper mold 2 moves downward, the limiting post 3 can be inserted into the limiting hole 7, allowing for immediate and intuitive judgment of the correspondence between the upper mold 2 and the lower mold 1. As the upper mold 2 continues to move downward, pressure is applied to the limiting post 3, causing the compression spring 6 to deform. The top plate frame 4 can then drive the top post 5 downward, allowing casting liquid to be poured into the mold. After molding, the operator only needs to activate the electric push rod 13, which moves the upper mold 2 upward, separating it from the lower mold 1. As the upper mold 2 moves upward, the limiting post 3 loses pressure, allowing the compression spring 6 to reset, which in turn moves the top plate frame 4 upward. The top post 5 then lifts the molded product upward, facilitating demolding without requiring the operator to press other mechanisms for demolding, greatly improving manufacturing efficiency.

[0025] In this embodiment, limit rings 8 are fixedly connected to both sides of the upper mold 2, and a column 9 is inserted into the inside of the limit ring 8.

[0026] In practical use, the limit ring 8 and the column 9 can limit the movement of the upper mold 2, making the movement of the upper mold 2 more stable.

[0027] In this embodiment, a baffle 10 is fixedly connected to the top of the column 9, and the bottom of the column 9 is fixedly connected to the upper surface of the support plate 11.

[0028] In practical use, the baffle 10 can effectively prevent the limiting ring 8 from detaching from the column 9.

[0029] In this embodiment, the support plate 11 is fixedly installed on the side of the lower mold 1, and the limiting ring 8 is connected to the support plate 11 through the support spring 12.

[0030] In practical use, the support spring 12 can provide a certain buffer when the electric push rod 13 is damaged and the upper mold 2 loses its tension and falls directly, thus reducing the probability of damage to the upper mold 2 and the lower mold 1.

[0031] In this embodiment, an electric push rod 13 is fixedly connected to the upper surface of the upper mold 2, and the electric push rod 13 is fixedly installed on the inner top wall of the fixed frame 14.

[0032] In practical use, the electric push rod 13 facilitates the control of the upper mold 2 to move in position.

[0033] In this embodiment, both ends of the fixed frame 14 are fixedly connected to the upper surface of the base plate 15. A support rod 16 is fixedly connected to the upper surface of the base plate 15. The top end of the support rod 16 is fixedly connected to the lower surface of the lower mold 1. The inner diameter of the limiting hole 7 is larger than the outer diameter of the top column 5.

[0034] In practical use, the base plate 15 and support rod 16 make the mold more stable and have better stability when placed.

[0035] Working principle: When in use, the operator can first start the electric push rod 13. The electric push rod 13 drives the upper mold 2 to move downward, so that the limiting ring 8 applies pressure to the support spring 12, compressing the support spring 12. As the upper mold 2 moves downward, the limiting post 3 can be inserted into the limiting hole 7. The upper mold 2 continues to move downward, which can apply pressure to the limiting post 3, causing the compression spring 6 to deform. The top plate frame 4 can drive the top post 5 to move downward, so that the casting liquid for the exhaust pipe can be poured into the mold. After molding, the operator only needs to start the electric push rod 13. The electric push rod 13 drives the upper mold 2 to move upward, which can separate the upper mold 2 from the lower mold 1. As the upper mold 2 moves upward, the limiting post 3 loses pressure, so the compression spring 6 can be reset, driving the top plate frame 4 to move upward. The top post 5 can lift the molded product upward, so that the product can be demolded.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
