Description

Technical Field

[0001] This utility model relates to the field of cylinder head demolding technology, and in particular to a quick-demolding cylinder head mold. Background Technology

[0002] The cylinder head is the cover of the engine and the component that seals the cylinder, including the water jacket, valves, and cooling fins. The cylinder head is made of cast iron or aluminum alloy and serves as the mounting base for the valve mechanism and the sealing cover for the cylinder. The function of the cylinder head is to seal the cylinder, form a combustion space together with the piston, and withstand the effects of high-temperature and high-pressure combustion gases.

[0003] Currently, during cylinder head demolding, the cylinder head injection molded part is tightly adhered to the mold and located inside the mold, making it difficult to remove the cylinder head. Using tools to make hard contact with the cylinder head can easily damage it before the cylinder head has fully hardened, and the removal speed is slow. Utility Model Content

[0004] The purpose of this application is to provide a quick-release cylinder head mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a quick demolding cylinder cover mold, including an equipment box, a concave mold fixed at the bottom of the inner cavity of the equipment box, a convex mold driven by a hydraulic cylinder at the top of the inner cavity of the equipment box, a slot opened at the bottom of the outer wall of the equipment box, a demolding mechanism installed in the slot, and a pulling mechanism for moving the demolding mechanism installed in the inner cavity of the equipment box;

[0006] The demolding mechanism includes a top plate located at the bottom of the inner cavity mold. Two sleeve rods are fixed to the bottom of the top plate, and a push rod is sleeved inside the sleeve rod. The bottom of the two push rods is fixed with the same connecting plate.

[0007] Preferably, the equipment box and the die are provided with through holes for the sleeve rod to pass through.

[0008] Preferably, a limiting ring is fixed to the top of the top rod, and a retaining ring is fixed to the bottom of the sleeve rod, with the limiting ring and the retaining ring abutting against each other.

[0009] Preferably, the hydraulic cylinder is fixed to the top of the inner cavity of the equipment box, and the output shaft of the hydraulic cylinder is fixed to the top of the punch.

[0010] Preferably, the pulling mechanism is fixed to the pull rods on both sides of the top of the connecting plate, and the top of the outer wall of the two pull rods is fixed with a connecting rod on the side that is close to each other. The two connecting rods are fixed with the same fixing ring, and the fixing ring is located on the top of the punch.

[0011] Preferably, the bottom of the connecting plate is in contact with the bottom of the inner wall of the groove.

[0012] Preferably, the outer wall of the slot is fixed with a protective plate by screws to provide protection.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] In this invention, the use of a housing, a concave mold, a convex mold, a hydraulic cylinder, a demolding mechanism, and a pulling mechanism, including a top plate, a push rod, a sleeve rod, and a connecting plate, and a fixing ring, a connecting rod, and a pull rod, enables the convex mold to move downwards and engage with the concave mold for pressing and molding. After molding, the hydraulic cylinder moves the convex mold upwards. When the convex mold is in contact with the fixing ring, the hydraulic cylinder moves it further upwards, causing the fixing ring to move upwards. This causes the connecting plate to move upwards via the pull rod, and the push rod on the connecting plate moves within the sleeve rod. When the retaining ring contacts the top of the connecting plate, it lifts the sleeve rod and the top plate, causing the top plate to move upwards within the concave mold and lift the formed cylinder head. When the convex mold moves downwards, the convex mold disengages from the fixing ring when the connecting plate contacts the bottom of the groove. The entire demolding mechanism then stops moving downwards, effectively solving the problems raised in the background art. This allows for further upward movement of the convex and concave molds while maintaining a safe height, completing the demolding process, making it convenient and practical.

[0023] Example: Reference Figure 1-4 The quick demolding cylinder cover mold shown includes an equipment box 1. The equipment box 1 has a concave mold 2 fixed at the bottom of its inner cavity, a convex mold 3 driven by a hydraulic cylinder 4 at the top of its inner cavity, a slot 5 opened at the bottom of the outer wall of the equipment box 1, a demolding mechanism 6 installed in the slot 5, and a pulling mechanism 7 installed in the inner cavity of the equipment box 1 to move the demolding mechanism 6.

[0024] The demolding mechanism 6 includes a top plate 9 located at the bottom of the inner cavity mold 2. Two sleeve rods 15 are fixed to the bottom of the top plate 9, and ejector rods 14 are sleeved inside the sleeve rods 15. The bottom of the two ejector rods 14 is fixed with the same connecting plate 16.

[0025] With the above structure, the equipment box 1 and the concave mold 2 are provided with through holes 13 for the sleeve rod 15 to pass through.

[0026] With the above structure: a limiting ring 17 is fixed at the top of the top rod 14, and a retaining ring 18 is fixed at the bottom of the sleeve rod 15. The limiting ring 17 and the retaining ring 18 are arranged to abut against each other.

[0027] With the above structure: the hydraulic cylinder 4 is fixed to the top of the inner cavity of the equipment box 1, and the output shaft of the hydraulic cylinder 4 is fixed to the top of the punch 3.

[0028] With the above structure: the pulling mechanism 7 is fixed to the pull rods 12 on both sides of the top of the connecting plate 16, and the outer top of the two pull rods 12 are fixed with connecting rods 11 on the side that is close to each other. The same fixing ring 10 is fixed between the two connecting rods 11, and the fixing ring 10 is located on the top of the punch 3.

[0029] With the above structure, the bottom of the connecting plate 16 contacts the bottom of the inner wall of the slot 5.

[0030] With the above structure, a protective plate 8 is fixed to the outer wall of the slot 5 by screws.

[0031] The working principle of this embodiment is as follows: The device includes an equipment box 1, a concave mold 2, a convex mold 3, a hydraulic cylinder 4, a demolding mechanism 6, and a pulling mechanism 7. The demolding mechanism 6 includes a top plate 9, a push rod 14, a sleeve rod 15, and a connecting plate 16. The pulling mechanism 7 includes a fixing ring 10, a connecting rod 11, and a pull rod 12. Through this structural design, the cylinder head forming mold is placed inside the concave mold 2 on the top plate 9. The hydraulic cylinder 4 operates, causing the convex mold 3 to move downwards and engage with the concave mold 2, achieving pressing and forming. After pressing, the hydraulic cylinder 4 drives the convex mold 3 upwards. When the convex mold 3 moves upwards and engages with the fixing ring 10, the hydraulic cylinder... 4. The punch 3 moves further upward, causing the fixing ring 10 to move upward. The connecting plate 16 moves upward via the pull rod 12. The push rod 14 on the connecting plate 16 moves within the sleeve rod 15. When the retaining ring 18 contacts the top of the connecting plate 16, it can lift the sleeve rod 15 and the top plate 9 to move. The top plate 9 moves upward within the concave mold 2, lifting the formed cylinder head. When the punch 3 moves downward, when the connecting plate 16 contacts the bottom of the inner wall of the slot 5, the punch 3 disengages from the fixing ring 10. The entire demolding mechanism 6 will not move downward anymore, effectively solving the problem raised in the background technology. It achieves further upward movement while maintaining a safe height for the punch 3 and the concave mold 2, completing the demolding, which is convenient and practical.
