Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an anti-clogging mold casting and unblocking mechanism. Background Technology

[0002] The mold is the core production unit in the casting process. By injecting flowing molten metal or non-metal into the mold, the molten metal fills the cavity inside the mold. After the molten metal cools and solidifies, the mold is opened to obtain the desired product structure.

[0003] Currently, during the pouring process of molten metal, if the mold cavity flow channel is too narrow, the molten metal tends to accumulate near the gate, resulting in slow feeding. Even if the pouring speed is slowed down, the improvement effect is limited. Furthermore, slowing down the pouring speed can cause the molten metal to cool down prematurely, further affecting its flow rate. In severe cases, it may even cause the flow channel to become blocked. Therefore, improvements are needed. Utility Model Content

[0004] To solve the above problems, this utility model provides an anti-clogging mold casting unblocking mechanism, including a feeding chamber and an unblocking component disposed on the feeding chamber. The feeding chamber has an upwardly inclined feeding port on one side and a discharge port at the bottom of the feeding chamber. The discharge port is movably connected to the casting port of the mold. The bottom of the feeding chamber has a conical structure. The unblocking component includes a drive motor, an eccentric wheel, and an unblocking rod. The drive motor is mounted above the feeding chamber via a bracket. The eccentric wheel is drivenly connected to the drive motor. The unblocking rod extends longitudinally and can move up and down into the feeding chamber. The unblocking rod and the discharge port are located in the same vertical direction. The upper end of the unblocking rod is drivenly connected to the eccentric wheel.

[0005] Preferably, a bearing seat is provided on each of the two sides above the bracket, the eccentric wheel is disposed between the two bearing seats and is rotatably connected to the bearing seats on both sides through a rotating shaft, and the drive motor is disposed on one side of the bracket through a support plate and is connected to one end of the rotating shaft for transmission.

[0006] Preferably, the upper end of the unblocking rod is provided with a transmission block, and a return spring is sleeved on the outer side of the unblocking rod at a position between the transmission block and the feeding chamber.

[0007] Preferably, a guide sleeve is provided at the position where the top of the feeding chamber is movably connected to the unblocking rod.

[0008] Preferably, the bottom sides of the feeding chamber are connected to the mold via hydraulic support rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a drive motor to rotate an eccentric wheel, which in turn drives a draining rod to move up and down reciprocally. When the draining rod moves downward into the discharge port, it can squeeze the molten liquid at the discharge port into the mold cavity and accelerate the flow of the molten liquid, preventing premature cooling and blockage of the flow channel, thereby improving the efficiency of molten liquid pouring.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 As shown, the anti-clogging mold casting and unblocking mechanism in this embodiment includes a feeding chamber 1 and a unblocking component disposed on the feeding chamber 1. The feeding chamber 1 has an upwardly inclined feeding port 2 on one side and a discharge port 3 at the bottom. The discharge port 3 is movably connected to the casting port of the mold 4, for example, by means of threaded connection or plug-in connection. The feeding chamber 1 has an exhaust port 5 on the side wall opposite to the feeding port 3. The bottom of the feeding chamber 1 has a conical structure, which is conducive to the molten liquid being gathered at the discharge port 3. The bottom sides of the feeding chamber 1 are supported and connected to the mold 4 by hydraulic support rods 6. The hydraulic support rods 6 can both play an auxiliary support role and can adaptively adjust the length.

[0018] The unblocking assembly includes a drive motor 7, a rotating shaft 8, an eccentric wheel 9, an unblocking rod 10, and a return spring 11. A bracket 12 is provided above the feeding chamber 1. The drive motor 7 is mounted on one side of the bracket 12 via a support plate 13 and is connected to one end of the rotating shaft 8 for transmission. A bearing seat 14 is provided on each side above the bracket 12. The eccentric wheel 9 is located between the two bearing seats 14 and is rotatably connected to the bearing seats 14 on both sides via the rotating shaft 8.

[0019] The unblocking rod 10 is inserted into the feed chamber 1 longitudinally and can move up and down. The unblocking rod 10 and the discharge port 3 are located in the same vertical direction. The upper end of the unblocking rod 10 is connected to the eccentric wheel 9 through the transmission block 15. In the initial state, the lower end of the unblocking rod 10 is suspended above the discharge port 3. The cross-sectional shape and size of the unblocking rod 10 and the discharge port 3 are the same, and the outer diameter of the unblocking rod 10 does not exceed the inner diameter of the discharge port 3.

[0020] A return spring 11 is sleeved on the outer side of the unblocking rod 10 at the position between the transmission block 15 and the feeding chamber 1, and a guide sleeve 16 is provided at the position where the top of the feeding chamber 2 is movably connected to the unblocking rod 10.

[0021] Among them, the drain rod 10 is a ceramic rod, or is covered with a ceramic layer. The melting point of most ordinary ceramics is above 2000℃, and the melting point of some high-strength ceramics can reach 3000℃. Common metals, such as iron, have a melting point of 1500-1600℃, copper has a melting point of 1000-1100℃, and aluminum has a melting point of 600-700℃. Therefore, it can be ensured that the drain rod 10 will not be melted and will not stick to the molten metal.

[0022] When this utility model is in use, the drive motor 7 drives the eccentric wheel 9 to rotate, which in turn drives the unblocking rod 10 to move up and down reciprocally. When the unblocking rod 10 enters the discharge port 3 downwards, it can squeeze the molten liquid at the discharge port 3 into the mold cavity and accelerate the flow of the molten liquid, preventing premature cooling and blockage of the flow channel, thereby improving the molten liquid pouring efficiency.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
