Description

Technical Field

[0001] This utility model relates to the field of motorcycle engine cylinder head mold technology, specifically to a blade and blade frame assembly and disassembly structure for a motorcycle engine cylinder head mold. Background Technology

[0002] In motorcycle engine cylinder head products with blades, the outer mold is typically designed in the shape of blades. Multiple layers of blades are stacked and fixed before being assembled into a blade frame. Currently, assembly is achieved using a combination of embedded parts and pins for positioning. However, when blades are damaged and require repair, or when exhaust gas needs to be cleaned every shift, the fit between the blade and the blade frame becomes extremely tight after the mold has been subjected to high temperatures, making disassembly and installation extremely difficult. Often, the blade needs to be hammered to remove it, which consumes a significant amount of time and manpower and can even lead to blade deformation and scrap. Traditional molds, such as... Figure 1 As shown.

[0003] In traditional assembly structures, blades and blade frames are connected through embedded fit and pin positioning. This structure is prone to difficulties in assembly and disassembly due to tight fit under high-temperature conditions, which increases maintenance costs and the risk of production delays, and urgently needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a disassembly and assembly structure for motorcycle engine cylinder head mold blades and blade frames. This structure enables convenient blade disassembly, reduces blade deformation caused by hammering, and extends mold life; it also reduces mold disassembly and maintenance time, thereby increasing production efficiency.

[0005] The purpose of this utility model is achieved by the following solution: a blade and blade frame mounting and dismounting structure for a motorcycle engine cylinder head mold, including a blade frame, a blade mounting groove provided in the blade frame, a blade installed in the blade mounting groove, a gap between the left side of the blade and the blade mounting groove, the front side and right side of the blade abutting against the blade mounting groove, a wedge groove provided in the middle section of the left side of the blade mounting groove, a wedge block installed in the wedge groove, the wedge groove is a wedge-shaped groove with a bottom area smaller than the opening area, the wedge block is a wedge-shaped structure that cooperates with the wedge groove, during the process of the wedge block being inserted into the wedge groove, the wedge block generates lateral pressure on the blade, so that the blade is tightly pressed into the blade mounting groove.

[0006] T-slots are provided on the left and right sides of the front end of the blade, and T-blocks are installed in the T-slots. The T-blocks are connected and fixed to the blade frame by bolts passing through the bolt holes of the T-blocks.

[0007] The wedge block is provided with wedge block bolt holes and wedge block release thread holes, and the wedge block is connected and fixed to the blade frame by bolts.

[0008] The wedge face of the wedge groove forms an angle of 5° with the side of the blade mounting groove, and the wedge angle of the wedge block is 5°.

[0009] Each blade in the blade mounting slot is fixed on the same axis by connecting pins, and the blade is fixed to the blade frame by bolts.

[0010] The blade is provided with a blade release thread hole that extends axially through the blade.

[0011] The blades and T-blocks are made of hot-work die steel, the blade frames are made of cast iron, and the wedge blocks are made of high-strength alloy steel.

[0012] The advantages of this utility model are: 1. Easy installation and disassembly: The wedge-shaped structure of the wedge block and the reserved gap simplify the loading and unloading process, saving a lot of time and labor costs; 2. High connection stability: The wedge block provides strong wedge force, ensuring stable connection of the blades under harsh environments such as long-term operation and vibration, reducing the risk of equipment failure; 3. Low maintenance cost: The convenient disassembly method avoids destructive disassembly of the blade frame, facilitates quick replacement of damaged blades, and extends the service life of the mold.

Detailed Implementation

[0014] like Figures 2 to 6As shown, a blade and blade frame assembly / disassembly structure for a motorcycle engine cylinder head mold includes a blade frame 1 with a blade mounting groove 3. A blade 2 is installed in the blade mounting groove 3, with a 1mm gap between the left side of the blade 2 and the blade mounting groove 3. The front side and right side of the blade 2 abut against the blade mounting groove 3. A wedge groove 4 is provided in the middle left section of the blade mounting groove 3, and a wedge block 5 is installed in the wedge groove 4. The wedge groove 4 is a wedge-shaped groove with a bottom area smaller than the opening area. The wedge block 5 is a wedge-shaped structure that cooperates with the wedge groove 4. During the insertion of the wedge block 5 into the wedge groove 4, the wedge block 5 exerts lateral pressure on the blade 2, causing the blade 2 to be tightly pressed into the blade mounting groove 3. T-slots 2-1 are provided on the left and right sides of the front end of the blade 2, and T-blocks 6 are installed in the T-slots 2-1. The T-blocks 6 are connected and fixed to the blade frame 1 by bolts passing through the bolt holes 1-1 of the T-blocks. Each blade 2 in the blade mounting groove 3 is fixed on the same axis by connecting pins, and the blade 2 is fixed to the blade frame 1 by bolts. The blade 2 is provided with an axially penetrating blade release threaded hole 2-2, facilitating the removal of the blade 2 by lifting screws. The wedge block 5 is provided with a wedge block bolt hole 5-1 and a wedge block release threaded hole 5-2. The wedge block 5 is fixed to the blade frame 1 by bolts, and the wedge block release threaded hole 5-2 facilitates the removal of the wedge block 5 by lifting screws. The wedge face of the wedge groove 4 forms a 5° angle with the side of the blade mounting groove 3, and the wedge angle of the wedge block 5 is 5°. The blade 2 and T-block 6 are made of hot-work die steel, the blade frame 1 is made of cast iron, and the wedge block 6 is made of high-strength alloy steel.

[0015] The following is the process of installing and removing the blades: Blade installation: 1. First, place the blade into the blade frame, close to the front and right sides of the blade mounting slot; 2. Then quickly insert the wedge block into the wedge groove and tighten the bolt; 3. Then accurately insert the T-block into the T-slot of the blade; 4. Finally, tighten the T-block bolts and the bolts connecting the blade to the blade frame to complete the blade installation.

[0016] Mold maintenance and disassembly: 1. The wedge block can be easily removed using the wedge block release screw; 2. Loosen the T-block bolts and the bolts connecting the blade to the blade frame; 3. Use the blade release screws to remove the blade from the blade mounting slot to complete the blade disassembly.
