DETAILED DESCRIPTION

[0024] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0025] As a specific embodiment, the exhaust valve hot pressing device of the embodiment of the utility model is easy to produce, which includes a hot pressing mold 1, a hot pressing device 2 and a functional part 4 connected to the hot pressing device 2. The functional part 4 is a device that cooperates with the hot pressing device 2 to enable the hot pressing device 2 to achieve or enhance the function. For example, the functional part 4 includes an electric control unit 41 that is electrically connected to the hot pressing body 21 described later and is a controller to achieve electrical control of the heating ring described later; the functional part 4 also includes a solenoid valve 42 and a pressure regulating valve 43 connected to the hot pressing lifting device 219 described later through an air pipe, etc., to achieve lifting action control and lifting speed control of the hot pressing lifting device 219.

[0026] The hot pressing device 2 includes a hot pressing body 21 and a hot pressing lifting device 219, and the output end of the hot pressing lifting device 219 is connected to the hot pressing body 21. The hot pressing body 21 can be heated. For example, a heating ring (not shown in the drawings) is provided on the hot pressing body 21, and the hot pressing body 21 is heated by the heating ring. For example, the hot pressing lifting device 219 is a cylinder to achieve lifting.

[0027] The hot pressing die 1 includes a hot pressing die body 11 with a positioning hole 111 at one end. After the exhaust valve 9 is transported to the positioning hole 111 below the hot pressing body 21 by manual labor or a conveying device, the heated hot pressing body 21 descends to achieve hot pressing of the exhaust valve 9. Usually, the hot pressing die body 11 is provided with a positioning adjustment hole 119 connected to the positioning hole 111, and a screw is screwed into the positioning adjustment hole 119 to abut the exhaust valve 9 in the positioning hole 111 to achieve fine-tuning positioning.

[0028] The hot pressing mold body 11 is provided with a positioning hole 111 at one end and the opposite end extends integrally to form a longitudinal extension body 12 and a transverse extension body 13. The hot pressing mold body 11 is parallel to the transverse extension body 13. It is easy to understand that the hot pressing mold body 11, the longitudinal extension body 12 and the transverse extension body 13 are an integral structure and are overall U-shaped.

[0029] The hot pressing lifting device 219 is fixedly connected to the transverse extension body 13 so that the hot pressing body 21 is directly opposite to the positioning hole 111 .

[0030] Since the hot pressing mold body 11, the longitudinal extension body 12 and the transverse extension body 13 are an integrated structure with a fixed shape, there is no need to adjust the position between the frame profiles, the assembly experience requirements for the production staff are relatively low, and production is convenient.

[0031] As one of the specific implementations, the hot pressing mold body 11, the longitudinal extension body 12 and the transverse extension body 13 are an integrated aluminum alloy structure.

[0032] As one of the specific implementations, an arc transition body 15 is provided inside the connection between the hot pressing mold body 11 and the longitudinal extension body 12, and / or inside the inner side of the longitudinal extension body 12 and the transverse extension body 13. This ensures the overall anti-deformation strength of the hot pressing mold body 11, the longitudinal extension body 12 and the transverse extension body 13, and prevents the distance between one end of the hot pressing mold body 11 and one end of the transverse extension body 13 from increasing.

[0033] As one of the specific embodiments, the hot stamping mold 1 further includes a stabilizing plate 14 directly or indirectly fixedly connected to the hot stamping mold body 11, and when viewed from above, the hot stamping mold body 11 has a portion located inside the stabilizing plate 14. When the stabilizing plate 14 is placed on a desktop or fixed on a rack, the hot stamping mold 1 can be stably arranged.

[0034] As one of the specific embodiments, the hot pressing mold 1 further includes a spacer 141, which is fixedly connected to the opposite ends of the stabilizing plate 14 and the hot pressing mold body 11 respectively, such as by screws, so that the hot pressing mold body 11 is indirectly fixedly connected to the stabilizing plate 14, and a gap exists between the opposite ends of the stabilizing plate 14 and the hot pressing mold body 11 where the locating hole 111 is opened. It is convenient to take out the exhaust valve 9 after hot pressing.

[0035] As one of the specific implementations, a force relief notch 16 is provided inside the connection between the hot pressing mold body 11 and the longitudinal extension body 12. Figure 5 As shown, the cross section of the force relief notch 16 is triangular. When the hot pressing body 21 descends to abut against the exhaust valve 9, one end of the lateral extension body 13 has a tendency to move away from the opposite end of the end of the hot pressing die body 11 where the positioning hole 111 is provided. The force relief notch 16 makes the deformation caused by this tendency mainly occur on the lateral extension body 13, and the deformation of the end of the hot pressing die body 11 where the positioning hole 111 is provided is relatively small, so that the exhaust valve 9 is easily transported to the positioning hole 111 by an automatic transport device or the like.

[0036] As one of the specific embodiments, a housing assembly 3 is also included, and the housing assembly 3 includes two side plates 31, two end plates 32, two top plates 33 and a plate connector 34. The side plates 31, the end plates 32 and the top plates 33 are fixedly connected by the plate connector 34 to form a receiving space (not shown in the drawings), and at least one of them is fixedly connected to the hot pressing mold 1. The receiving space can accommodate air pipes, wires, etc. Usually, at least one of the side plates 31, the end plates 32 and the top plates 33 is provided with a through hole 39 to realize the routing of the pipeline.

[0037] As one of the specific implementations, the side panels 31 , the end panels 32 , and the top panel 33 are all made of acrylic panels.

[0038] As one of the specific implementations, the functional component 4 includes at least one of an electrical control component 41 , a solenoid valve 42 , and a pressure regulating valve 43 , and the functional component 4 is fixed on the housing assembly 3 .

[0039] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0040] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0041] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0042] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the national standard for dimensional tolerance.
