Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an engine cylinder head die-casting mold. Background Technology

[0002] The engine cylinder head, also called the cylinder cover, is an important component of the engine. It is installed on top of the engine block and seals the upper opening of the cylinder like a cover. Together with the cylinder block, piston, etc., it forms a sealed space to ensure that the high-temperature and high-pressure gases in the combustion chamber do not leak when the engine is running, and to ensure that the combustion process takes place in a sealed environment. Because the cylinder head has many holes and an irregular structure, the existing technology uses a casting process to process it. It relies on gravity to naturally fill the mold. The process is simple and the requirements for the mold are lower, but the production efficiency is low.

[0003] Die casting uses high pressure (usually tens to hundreds of megapascals) to rapidly press molten metal into a metal mold. The filling time is extremely short (0.01-0.2 seconds). The mold must be made of special alloy steel to withstand the pressure. The processing speed is fast, but the requirements for the mold are high, especially the demolding of each hole. Utility Model Content

[0004] The purpose of this invention is to provide an engine cylinder head die casting mold suitable for the engine cylinder head die casting process, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an engine cylinder head die-casting mold, comprising a fixed mold component, a moving mold component, and an intermediate mold, wherein the intermediate mold is located between the fixed mold component and the moving mold component, and a lateral movable mold is provided in the intermediate mold, which can move to open and close the mold. Through the cooperation of the fixed mold component, the moving mold component, the intermediate mold, and the lateral movable mold, an engine cylinder head die-casting cavity is formed for die-casting the engine cylinder head; a pushing slide is fixedly installed on one side of the lateral movable mold, and the pushing slide can slide in the intermediate mold, thereby driving the lateral movable mold to move to open and close the mold.

[0006] The surface of the pusher slide is provided with a T-shaped push groove, and a boss is provided in the T-shaped push groove. The boss is locked in the T-shaped push groove. The axial movement of the boss drives the pusher slide to move, thereby causing the lateral movable mold to move.

[0007] A hydraulic cylinder shaft is coaxially fixedly installed at one end of the boss, and a hydraulic cylinder fixing plate is fixedly provided on the surface of the intermediate mold. A hydraulic cylinder assembly is fixedly installed on the hydraulic cylinder fixing plate, and the hydraulic cylinder assembly is used to drive the hydraulic cylinder shaft to move axially.

[0008] A synchronous plate is fixedly installed on the surface of the cylinder shaft, and a detection synchronous shaft is fixedly installed on the synchronous plate. When the cylinder shaft moves axially, the cylinder shaft can drive the detection synchronous shaft to move axially through the synchronous plate. By detecting the position of the detection synchronous shaft, the position detection of the cylinder shaft and the lateral movable mold can be realized.

[0009] The cylinder assembly is externally fixed with a back plate, and a positioning sleeve is fixedly installed on the back plate. The detection synchronous shaft passes through the positioning sleeve, and the positioning sleeve limits the movement of the detection synchronous shaft.

[0010] The surface of the detection synchronous shaft is fixedly provided with a protruding ring, and the surface of the fixed back plate is fixedly provided with a contact switch. When the detection synchronous shaft undergoes axial displacement, the contact switch can detect it, thereby determining the position of the lateral movable module that moves synchronously with the detection synchronous shaft.

[0011] The contact switch is provided with a switch detection shaft, and a contact wheel is rotatably mounted at the end of the switch detection shaft. When the detection synchronous shaft moves axially, it drives the convex ring to move axially. The convex ring is pressed against the contact wheel, which drives the switch detection shaft to move relative to the contact switch, thereby realizing the trigger detection of the contact switch.

[0012] The fixed mold component is provided with a main channel bushing, through which molten metal is fed into the engine cylinder head die-casting cavity formed by the fixed mold component, the moving mold component, the intermediate mold and the side movable mold; the moving mold component is fixedly installed with a guide post component, which is inserted into the intermediate mold to position the intermediate mold.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model of engine cylinder head die casting mold is suitable for engine cylinder head die casting production. Compared with traditional casting technology, the produced engine cylinder head has a smooth surface, high dimensional accuracy, and can improve production efficiency.

[0015] The sliding mechanism allows for the demolding of various holes on the surface of the engine cylinder head, such as the intake and exhaust ports, spark plugs, and oil cylinders, reducing secondary processing after molding and further improving processing efficiency.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: an engine cylinder head die-casting mold, including a fixed mold component 1, a moving mold component 2, and an intermediate mold 3. The intermediate mold 3 is located between the fixed mold component 1 and the moving mold component 2. A lateral movable mold 4 is provided in the intermediate mold 3. The lateral movable mold 4 can move to open and close the mold. The fixed mold component 1, the moving mold component 2, the intermediate mold 3, and the lateral movable mold 4 cooperate to form an engine cylinder head die-casting cavity for die-casting the engine cylinder head. A pushing slide 5 is fixedly installed on one side of the lateral movable mold 4. The pushing slide 5 can slide in the intermediate mold 3. The pushing slide 5 drives the lateral movable mold 4 to move to open and close the mold.

The boss 502 is locked in the T-shaped pushing groove 501. The axial movement of the boss 502 drives the pushing slide 5 to move, thereby causing the lateral movable mold 4 to move.

[0023] like Figure 2As shown, a hydraulic cylinder shaft 503 is coaxially fixedly mounted on one end of the boss 502. A hydraulic cylinder fixing plate 504 is fixedly mounted on the surface of the intermediate mold 3, and a hydraulic cylinder assembly 505 is fixedly mounted on the hydraulic cylinder fixing plate 504. The hydraulic cylinder assembly 505 is used to drive the hydraulic cylinder shaft 503 to move axially. A synchronous plate 506 is fixedly mounted on the surface of the hydraulic cylinder shaft 503, and a detection synchronous shaft 507 is fixedly mounted on the synchronous plate 506. When the hydraulic cylinder shaft 503 moves axially, the hydraulic cylinder shaft 503 can drive the detection synchronous shaft 507 to move axially through the synchronous plate 506. By detecting the position of the detection synchronous shaft 507, the position detection of the hydraulic cylinder shaft 503 and the lateral movable mold 4 can be realized.

[0024] A fixed back plate 508 is externally mounted on the cylinder assembly 505. A positioning sleeve 509 is fixedly mounted on the fixed back plate 508. The detection synchronous shaft 507 passes through the positioning sleeve 509, which limits the movement of the detection synchronous shaft 507. A protruding ring portion 510 is fixedly provided on the surface of the detection synchronous shaft 507, and a contact switch 511 is fixedly provided on the surface of the fixed back plate 508. When the detection synchronous shaft 507 undergoes axial displacement, the contact switch 511 can detect it, thereby determining the position of the lateral movable module 4 that moves synchronously with the detection synchronous shaft 507.

[0025] The contact switch 511 is provided with a switch detection shaft 512, and a contact wheel 513 is rotatably mounted on the end of the switch detection shaft 512. When the detection synchronization shaft 507 moves axially, it drives the convex ring 510 to move axially. The convex ring 510 and the contact wheel 513 are pressed together, driving the switch detection shaft 512 to move relative to the contact switch 511, thereby realizing the trigger detection of the contact switch 511.

[0026] The fixed mold component 1 is provided with a main channel bushing 101, through which molten metal is input into the engine cylinder head die-casting cavity formed by the fixed mold component 1, the moving mold component 2, the intermediate mold 3 and the side movable mold 4; the moving mold component 2 is fixedly installed with a guide post component 201, which is inserted into the intermediate mold 3 to position the intermediate mold 3.

[0027] The intermediate mold 3 is also equipped with an intake mandrel 301, an exhaust mandrel 302, and a mandrel cylinder 303. The intake mandrel 301 and the exhaust mandrel 302 cooperate with the engine cylinder head die-casting cavity to form the engine cylinder head's air inlet and exhaust outlet, respectively. The mandrel cylinder 303 is used to control the movement of the intake mandrel 301 and the exhaust mandrel 302. During the die-casting process, the intake mandrel 301 and the exhaust mandrel 302 are inserted into the engine cylinder head die-casting cavity to form the engine cylinder head's air inlet and exhaust outlet, preventing molten metal from blocking the air inlet and exhaust outlet. When the mold is opened, the mandrel cylinder 303 drives the extraction of the corresponding intake mandrel 301 and exhaust mandrel 302, respectively.
