Description

Technical Field

[0001] This utility model relates to the field of die-casting molds for throttle valve bodies, specifically a novel mold structure for a throttle valve. Background Technology

[0002] The throttle valve, also known as the engine control valve, is a key component that controls the intake air of the engine. Its main function is to adjust the engine's power output and fuel consumption by changing the amount of air entering the engine. The driver controls the opening angle of the throttle valve by operating the accelerator pedal, thereby controlling the vehicle's acceleration and deceleration.

[0003] The throttle valve body is made of aluminum alloy and can be produced by die casting. However, existing throttle valve body molds can only form one at a time, meaning they are all single-cavity molds, limiting the number of valves that can be produced. Therefore, we propose a novel mold structure for throttle valves. Utility Model Content

[0004] This invention provides a novel mold structure for a throttle valve, which has the advantage of being able to form multiple throttle valve bodies in a single die casting process, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A novel mold structure for a throttle valve is designed, including two first mold bases merged together. Throttling valve body cavities are provided at the edges of the contact surfaces of the two first mold bases. When the two first mold bases are merged, the throttle valve body cavities at the edges of the two first mold bases merge. Each throttle valve body cavity is connected to the edge of the first mold base on one side. The system also includes second mold bases distributed on both sides of the first mold bases. Forming stops corresponding to the throttle valve body cavities are provided on the sides of the second mold bases.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 3 This utility model provides a technical solution: a novel mold structure for a throttle valve, comprising two first mold bases 1 joined together, with the ends of the two first mold bases 1 that are far apart from each other mounted on a first mounting plate 5, and mounting holes provided on the edge of the first mounting plate 5;

[0023] like Figure 1 As shown, the first mold base 1 is provided with second mold bases 7 on both sides. The two second mold bases 7 are respectively placed on the two sides of the first mold base 1. The two second mold bases 7 are respectively set on the side away from each other on the second mounting plate 6. The edge of the second mounting plate 6 is also provided with mounting holes. Therefore, when installing the mold, the first mounting plate 5 and the second mounting plate 6 can be fastened to the die casting machine tool with bolts.

[0024] like Figure 1 and Figure 2 As shown, the mold is in the closed state at this time, that is, the two first mold bases 1 are joined together, and the second mold base 7 is joined to both sides of the first mold base 1.

[0025] Furthermore, such as Figure 3 As shown, a throttle valve body cavity 10 is provided at the edge of the contact surface of the two first mold bases 1. When the two first mold bases 1 are combined, the throttle valve body cavities 10 at the edges of the two first mold bases 1 are combined, that is, the shape of each throttle valve body cavity 10 on the two first mold bases 1 after splicing is consistent with the shape of the throttle valve body.

[0026] It should be noted that when designing the throttle valve body cavity 10, each throttle valve body cavity 10 needs to be connected to the edge of the first mold base 1 on one side, and the throttle valve body cavities 10 on the surface of one of the first mold base 1 are interconnected through flow grooves 13, such as... Figure 3 As shown, the cavities 10 of each throttle valve body are connected in an "S-shape" bend.

[0027] The second mold base 7 is provided with forming stop 12 on its side, which corresponds to the throttle valve body cavity 10. When the second mold base 7 is placed on the side of the first mold base 1, the forming stop 12 is also placed in the throttle valve body cavity 10. However, there is a forming gap between the forming stop 12 and the throttle valve body cavity 10.

[0028] It should be noted here that the existing throttle valve body structure, such as Figure 4 and Figure 5 As shown, point A on the throttle valve body is the position for installing the valve stem, point B is the position for installing the gear set, and point C is the position for installing the motor. When the second mold base 7 is placed on the side of the first mold base 1, the gap between the forming stop 12 and the throttle valve body cavity 10 forms the valve body shape at point B.

[0029] like Figure 4 As shown, the forming stop 12 has a first positioning post 11 and a second positioning post 2 on the side facing the first mold base 1. The first positioning post 11 and the second positioning post 2 are placed inside the throttle valve body cavity 10. The position of the first positioning post 11 corresponds to the position at point C, and the position of the second positioning post 2 corresponds to the position at point A. When the first positioning post 11 and the second positioning post 2 are placed inside the throttle valve body cavity 10 at the same time, the corresponding cavity can be formed at the corresponding position of the throttle valve body during the casting process.

[0030] like Figure 3 As shown, a slot 14 corresponding to the first positioning post 11 is provided on the surface of the throttle valve body cavity 10. When the two first mold bases 1 are merged, the two slots 14 are also merged together. That is, the shape of the merged slot 14 matches the hole at point A.

[0031] The molten metal is injected into the mold as follows: a die-casting hole 8 is provided on one side of the first mold base 1, and the die-casting hole 8 is connected to the cavities 10 of the throttle valve body. That is, molten metal can be injected into each cavity 10 of the throttle valve body through the die-casting hole 8. Figure 3 As shown, an overflow channel 9 is provided on one side of the first mold base 1, and the overflow channel 9 and the die-casting hole 8 are distributed at both ends of the first mold base 1.

[0032] In practical application, one of the two first mold bases 1 is a moving mold, and the other is a stationary mold. After die casting is completed, except for the stationary mold, such as... Figure 2 As shown, the second mold base 7 moves toward both sides of the first mold base 1, and finally the moving mold opens, at which point multiple throttle valve bodies can be formed at once.

[0033] Furthermore, to facilitate preheating of the first mold base 1 and the second mold base 7, and to allow the first mold base 1 and the second mold base 7 to quickly reach the die-casting temperature, such as... Figure 1 As shown, a heating groove 4 is provided in the middle of the side of the first mounting plate 5 and the second mounting plate 6. The heating groove 4 extends into the first mold base 1 and the second mold base 7 respectively. A heating element is provided in each heating groove 4. The heating element is a heating rod, heating wire or PTC heater, etc. The heating groove 4 is connected to a temperature controller and can perform temperature control.

[0034] like Figure 1As shown, each heating tank 4 has a detachable sealing plate 3 at its opening. The edge of the sealing plate 3 is fastened to the edge of the opening with bolts, making it convenient to open the heating tank 4 for maintenance.

[0035] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
