Description

Technical Field

[0001] The utility model relates to the technical field of heating for die-casting dies, in particular to a heating device for die-casting dies which can be heated evenly. Background Art

[0002] A die-casting mold is a tool used to cast metal parts. It presses molten metal into the mold cavity through a runner, maintains pressure, cools, and solidifies before forming the die-cast part. Before casting the liquid metal, the mold must be preheated to prevent the high-temperature liquid metal from directly heating the mold, causing the liquid metal to cool and prevent the die-casting process from proceeding.

[0003] According to a publicly disclosed die-casting mold preheating device (Announcement No.: CN219324745U), in the above application, the adjustment hole on the adjustment disk and the air outlet hole on the preheating disk are partially misaligned by rotating the adjustment disk, and the limiting ring restricts the adjustment disk to adjust the size of the air outlet hole according to the die-casting of different metals, so that the combustion gas is gathered or dispersed, so that the combustion gas can heat the die-casting mold more quickly.

[0004] The adjustment dial is not equipped with an effective limiter mechanism, which makes it easy for workers to accidentally rotate the adjustment dial during operation by touching the lever. This unintentional rotation can change the alignment between the outlet and the adjustment hole, thereby affecting the flow and distribution of the combustion gas, and ultimately the heating effect of the die-casting mold. During use, the deviation and movement of the heating tube body can also cause the adjustment dial to rotate, which in turn affects the discharge of combustion gas. Unstable rotation of the adjustment dial not only leads to uneven distribution of combustion gas flow, but also affects heating efficiency, prolonging the heating time of the die-casting mold and even causing uneven heating. This not only increases production costs but also reduces the quality of the die-casting, causing defects such as cracks and deformation. Utility Model Content

[0025] The movable assembly 8 includes a slide slot 80, which is opened on the side of the fixed seat 70 close to the rotating plate 77. The inner wall of the slide slot 80 is slidably connected to a movable column 81, and a spring 2 82 is fixed to the surface of the movable column 81. The end of the spring 2 82 away from the movable column 81 is fixed to the inner wall of the slide slot 80. The side of the rotating plate 77 close to the fixed seat 70 is provided with a connecting groove 1 83, and the side of the rotating plate 77 close to the fixed seat 70 is provided with a connecting groove 2 84. The end of the movable column 81 away from the spring 2 82 is set to an arc. When the rotating plate 77 is rotated, the inner wall of the connecting groove 1 83 contacts the curved surface of the movable column 81, and the movable column 81 enters the slide slot 80. The spring 2 82 is compressed. When the position of the movable column 81 is parallel to the position of the connecting groove 2 84, the spring 2 82 is released, which allows the movable column 81 to enter the connecting groove 2 84, thereby stabilizing the rotating plate 77 and preventing the rotating plate 77 from self-rotation deviation.

[0026] The surface of the heating tube body 1 is connected to a sealing cover 3 through a thread, and a handle 6 is fixed to the surface of the adjusting disk 5. The end of the handle 6 away from the adjusting disk 5 passes through the through hole 2 700. After removing the sealing cover 3, the fan can be connected, which can save energy and increase the fire, give full play to the heat, and improve efficiency. When the handle 6 is rotated, the adjusting disk 5 can be driven to rotate synchronously, which is convenient for adjustment.

[0027] When in use, insert the pipeline of the storage tank of external combustion gas such as natural gas, coal gas, etc. into the gas access pipe 2, place the two preheating disks 4 between the upper mold and the lower mold of the die-casting mold, open the valve on the external combustion gas storage tank, and the combustion gas enters the heating tube body 1 and is transported along the heating tube body 1 to the preheating disk 4 until it is discharged from the air outlet, ignites the combustion gas, and the combustion gas heats the upper mold and the lower mold, and can preheat the upper mold and the lower mold of the die-casting mold at the same time. It is easy to use, has a fast preheating speed for the die-casting mold, high efficiency, and uniform heating. When it is necessary to adjust the gathering or dispersion of the combustion gas, the handle 6 is turned at this time to drive the adjusting disk 5 to rotate. At this time, the handle 6 moves in the through hole 2 700 without affecting the normal movement of the handle 6. The gas outlet size can be adjusted by misalignment between the adjusting disk 5 and the air outlet of the preheating disk 4. At the same time, when the adjusting disk 5 rotates, the inner wall of the slot 74 contacts the surface of the block 72. At this time, the block 72 moves away from the adjusting disk 5, and the spring 1 73 is compressed. At the same time, the block 72 When moving, the fixing rod 75 is driven to move in the connecting groove 79 without affecting the normal movement of the block 72. When the position of the block 72 is parallel to the slot 74, the spring 1 73 is released, which can drive the block 72 to enter the slot 74. When the adjustment is completed, the rotating plate 77 is rotated. At this time, the inner wall of the connecting groove 1 83 contacts the arc surface of the movable column 81, so that the movable column 81 enters the sliding groove 80, and the spring 2 82 is compressed. When the position of the movable column 81 is parallel to the position of the connecting groove 2 84, the spring 2 82 is released, which can make the movable column 81 enter the sliding groove 80. When the movable column 81 enters the second connecting groove 84, the rotating plate 77 can be stabilized to prevent the rotating plate 77 from rotating and deviating. At this time, the connecting groove 79 and the fixing rod 75 are staggered, and the inner wall of the annular groove 78 contacts the surface of the fixing rod 75, which can limit the fixing rod 75 and the block 72. If the handle 6 is accidentally touched, the inner wall of the groove 74 contacts the surface of the block 72, and the adjusting disk 5 cannot be rotated, thereby avoiding the deviation and rotation of the adjusting disk 5 caused by accidental touching, and avoiding uneven distribution of combustion gas flow, which affects the heating efficiency.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
