Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to an automatic opening and closing mechanism for casting molds. Background Technology

[0002] Casting molds are indispensable equipment in modern manufacturing, widely used in the molding and processing of materials such as plastics, metals, and ceramics. Their main function is to inject liquid materials into the mold cavity, where they are cooled or solidified to form the desired product.

[0003] In the prior art, a search revealed a Chinese patent entitled "An Automatic Opening and Closing Mechanism for Casting Molds," application number "202321030824.4." This patent mainly includes a supporting base plate and a mold. Side plates are vertically fixed to the top edges of the supporting base plate, and a discharge window is provided in the middle of the supporting base plate. A mold opening and closing assembly is provided on each of the top two sides of the supporting base plate. The mold opening and closing assembly consists of a telescopic cylinder, a mold mounting frame, and a mold fixing frame. The telescopic cylinder is vertically fixed to the side plate. The front of the mold mounting frame has a cavity for placing the mold, and a mold fixing frame is provided on each of the two sides of the mold mounting frame. Although this utility model uses a mold opening and closing assembly to control the opening and closing of the mold, and the mold does not require additional locking buckles after closing, resulting in a simpler structure and lower failure rate, various factors, such as the complex shape of the casting part, improper surface treatment of the mold cavity, and the characteristics of the casting material, may lead to adhesion between the casting part and the mold cavity. When the aforementioned mold is opened, directly ejecting the material using ejector pins may result in uneven material ejection and damage to the casting due to excessive ejection force, thus affecting product quality and production efficiency. Therefore, this utility model provides an automatic opening and closing mechanism for casting molds to solve the problems mentioned in the background art. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model discloses an automatic opening and closing mechanism for a casting mold, comprising two fixed plates 2, with four guide rods 3 evenly fixedly connected between the fixed plates 2. A movable mold 1 is slidably connected to the outer side of the guide rods 3. A fixed mold 4 is fixedly connected to one of the fixed plates 2 near the movable mold 1. A casting port 5 is provided on the top of the fixed mold 4. An inflation assembly for inflating the fixed mold 4 is provided on the top of the fixed mold 4 and on the side of the casting port 5. The inflation assembly includes an L-shaped movable frame 7 slidably connected to the top of the fixed mold 4, a first electric push rod 8 fixedly connected to the top of the movable frame 7, and a second electric push rod 8 fixedly connected to the first electric push rod 9. The cover plate 9 at the bottom of the piston rod of the electric push rod 8 is fixedly connected to the top of the fixed mold 4 and located on one side of the movable frame 7. The second electric push rod 10 is fixedly connected to the top of the fixed mold 4 and located on one side of the second electric push rod 10. The connecting hose 12 is fixedly connected to the air outlet of the air pump 11 and the air inlet pipe 15 is fixedly connected inside the cover plate 9. The movable frame 7 is fixedly connected to the end of the piston rod of the second electric push rod 10. The connecting hose 12 is connected to the air inlet pipe 15. The bottom of the cover plate 9 is fixedly connected to a sealing gasket 16, which can effectively seal the connection between the cover plate 9 and the pouring gate 5.

[0024] After the movable mold 1 and the fixed mold 4 are closed, the pouring material can be easily poured in through the sprue 5. After the casting is completed, the second electric push rod 10 moves the movable frame 7 and its first electric push rod 8 towards the sprue 5. The operation of the first electric push rod 8 causes the cover plate 9 to close at the sprue 5, controlling the operation of the air pump 11 to inflate the mold cavity through the connecting hose 12 and the air inflator 15. This inflation facilitates the separation of the casting from the mold cavity, reducing the difficulty of unloading the casting due to adhesion to the mold cavity, thus facilitating subsequent ejection and unloading operations, and improving the efficiency and product quality of casting production.

[0025] A slide rod 18 is slidably connected inside the fixed mold 4. A top plate 17 is fixedly connected to one end of the slide rod 18 near the moving mold 1. The top plate 17 is slidably connected inside the fixed mold 4. An end plate 6 is fixedly connected to one end of the slide rod 18 opposite to the top plate 17. A spring 19 is sleeved on the outside of the slide rod 18 and on one side of the end plate 6. A connecting frame 13 is fixedly connected to one side of the moving mold 1. The end of the connecting frame 13 extends to one side of the end plate 6.

[0026] After casting is completed, the moving mold 1 separates from the fixed mold 4 for mold opening. When the moving mold 1 moves, it drives the connecting frame 13 to move towards the end plate 6. When the connecting frame 13 pushes the end plate 6 and its sliding rod 18 to move, the top plate 17 can be moved, which facilitates the automatic unloading of the casting part from the inside of the fixed mold 4.

[0027] The sprue 5 is funnel-shaped with a large opening at the top for easy pouring. A discharge port 14 is located on one side of the fixed mold 4 and at the bottom of the moving mold 1, through which the ejected castings can be collected.

[0028] When the moving mold 1 and the fixed mold 4 are closed, the end of the connecting frame 13 near the end plate 6 is spaced apart from the end plate 6 to ensure that the fixed mold 4 moves a certain distance before the ejection of the casting part is carried out.

[0029] Working Principle: After the movable mold 1 and the fixed mold 4 are closed, the casting material can be easily poured in through the sprue 5. After the casting part is formed, the second electric push rod 10 moves the movable frame 7 and its first electric push rod 8 towards the sprue 5. The operation of the first electric push rod 8 causes the cover plate 9 to close at the sprue 5, controlling the operation of the air pump 11 to inflate the mold cavity through the connecting hose 12 and the air inflator 15. This inflation facilitates the separation of the casting part from the mold cavity, reducing the difficulty of unloading caused by the casting part sticking to the mold cavity, thus facilitating subsequent ejection and unloading operations, and improving the efficiency and product quality of casting production.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
