[0023] Example:

[0024] Reference Figure 1-Figure 5The embodiment of the utility model provides a fully automatic mold opening and closing device, including a base plate 1, and also includes: a base 2 with a cavity inside, which is fixedly connected to the top of the base plate 1; wherein, a placement frame 3 is fixedly connected to the top of the base 2 for installing the fixed mold of the mold, and a frame 4 is fixedly connected to the base plate 1; a mounting plate 5 is connected to the frame 4 through a driving part for installing the movable mold of the mold, and the mounting plate 5 is located directly above the placement frame 3, and the driving part is used to drive the mounting plate 5 to rise and fall; two air guide covers 6 are connected to the frame 4 through an air supply part; wherein, the port of the air guide cover 6 faces the placement frame 3, when the mounting plate 5 descends, negative pressure is generated in the air guide cover 6, and when the mounting plate 5 rises, positive pressure is generated in the air guide cover 6; both sides of the mounting plate 5 are provided with connecting parts for driving the air guide cover 6 to swing, so as to expand the blowing range of the air guide cover 6.

[0025] Specifically, when the mold needs to be opened, the cylinder 51 can be started and the mounting plate 5 can be driven to move upward, while the movable mold can be driven to separate from the fixed mold and automatically open upward. During the upward movement of the mounting plate 5 and the movable mold, the telescopic airbag 61 is squeezed so that the air inside it is blown toward the product in the fixed mold through the air pipe 62 and the air guide cover 6, which can cool the product after the mold is opened again, and the residual heat on the product can be taken away by the flowing air, thereby avoiding residual heat on the product after the mold is opened, and reducing the risk of product deformation.

[0026] In another embodiment, an air intake pipe may be fixedly connected to the telescopic airbag 61, and one-way valves may be fixedly installed in the air intake pipe and the air supply pipe 62, so that the air intake pipe can only inhale air and the air supply pipe 62 can only exhaust air. Therefore, when the telescopic airbag 61 is stretched, only the air intake pipe will inhale air, and when the telescopic airbag 61 is squeezed, only the air supply pipe 62 will exhaust air. In this way, the air supply pipe 62 may be prevented from absorbing hot air and floating dust to repeatedly heat and contaminate the mold. In order to prevent floating dust from contaminating the telescopic airbag 61, a filter element for filtering dust may be installed in the air intake pipe.

[0027] The driving part includes a cylinder 51 fixedly connected to the frame 4 , an output end of the cylinder 51 is fixedly connected to a fixing plate 52 , and the mounting plate 5 is fixedly connected to the fixing plate 52 .

[0028] Specifically, by starting the cylinder 51, the output end of the cylinder 51 drives the fixed plate 52 to move longitudinally, and drives the mounting plate 5 and the movable mold to move synchronously, so that the mold can be automatically opened and closed.

[0029] The air supply part includes a telescopic airbag 61 fixedly connected to the top of the mounting plate 5, and an air supply pipe 62 is connected to the telescopic airbag 61; the end of the air supply pipe 62 is connected to the air guide cover 6, and a spring 63 is fixedly connected to the outer wall of the air guide cover 6, and the end of the spring 63 away from the air guide cover 6 is fixedly connected to the frame 4.

[0030] Specifically, during the descending process of the mounting plate 5, the telescopic airbag 61 is stretched, so that negative pressure is generated in the air guide cover 6. Under the action of the negative pressure, the outside air enters the telescopic airbag 61 through the air guide cover 6 and the air pipe 62. During the upward movement of the mounting plate 5 and the movable mold, the telescopic airbag 61 is squeezed, so that the air inside it is blown toward the product in the fixed mold through the air pipe 62 and the air guide cover 6, so that the product can be cooled again after the mold is opened.

[0031] The connecting part includes a straight plate 71 fixedly connected to the frame 4 and a vertical plate 74 fixedly connected to the mounting plate 5; a straight rod 72 is rotatably connected to the straight plate 71, one end of the straight rod 72 is fixedly connected to the air guide cover 6, and the other end of the straight rod 72 is fixedly connected to a cam 73; a plurality of arc blocks 75 are fixedly connected to the vertical plate 74, and when the mounting plate 5 moves up and down, the plurality of arc blocks 75 will slide over the cam 73 in sequence.

[0032] Specifically, in the process of the mounting plate 5 and the movable mold moving upward, the vertical plate 74 and the arc block 75 are also driven to move upward, and the cam 73 and the air guide cover 6 are driven to move through the arc block 75. When the cam 73 is separated from the vertical plate 74, the air guide cover 6 is restored to its initial position through the spring 63. Through the cooperation of the spring 63 and multiple arc blocks 75, the reciprocating swing of the air guide cover 6 can be realized to expand the blowing range of the air guide cover 6 and make the flowing air act evenly on the product.

[0033] The number of the springs 63 is four, and the number of the telescopic airbags 61 is two.

[0034] Specifically, such a design can better support the wind guide cover 6, thereby improving the stability of the wind guide cover 6, and the two telescopic air bags 61 can provide sufficient gas and blow it out through the two wind guide covers 6 to ensure the heat dissipation effect.

[0035] An electric push cylinder 81 is fixedly connected inside the base 2, and a cross plate 82 is fixedly connected to the output end of the electric push cylinder 81. Moving plates 83 are slidably connected to the four sides of the top of the base 2. Connecting rods 84 are rotatably connected to the two sides of the bottom of the moving plate 83, and the end of the connecting rod 84 away from the moving plate 83 is rotatably connected to the cross plate 82. A plurality of elastic telescopic rods 85 facing the placement frame 3 are fixedly connected to the four moving plates 83, and the elastic telescopic rods 85 are slidably connected to the placement frame 3.

[0036] Specifically, firstly, the fixed mold of the mold is placed in the placement frame 3, and then the electric push cylinder 81 is started. The output end of the electric push cylinder 81 drives the horizontal plate 82 to move downward, and drives the connecting rod 84 to move, so that the four movable plates 83 move toward each other, and drive multiple movable plates 83 to clamp and fix the fixed mold, which can clamp and fix molds of different sizes, and through multiple elastic telescopic rods 85, it can also be suitable for the outer wall shapes of different molds, so as to achieve a better clamping effect, and then the movable mold of the mold is fixed to the bottom of the mounting plate 5;

[0037] On the other hand, the bottom of the mounting plate 5 can adopt the same clamping structure as that in the placement frame 3 to clamp and fix the movable mold of the mold.

[0038] Working principle: During the use of this fully automatic mold opening and closing device, first place the fixed mold of the mold in the placement frame 3, then start the electric push cylinder 81, the output end of the electric push cylinder 81 drives the cross plate 82 to move downward, and drives the connecting rod 84 to move, so that the four movable plates 83 all move toward the placement frame 3, and drive multiple elastic telescopic rods 85 to clamp and fix the fixed mold, which can clamp and fix molds of different sizes, and through multiple elastic telescopic rods 85, it can also be suitable for the outer wall shapes of different molds, so as to achieve a better clamping effect, and then fix the movable mold of the mold at the bottom of the mounting plate 5;

[0039] When in use, by starting the air cylinder 51, the output end of the air cylinder 51 drives the fixed plate 52 to move downward, and drives the mounting plate 5 and the movable mold to move synchronously, so that the movable mold is covered on the fixed mold for automatic mold closing. At the same time, during the descending process of the mounting plate 5, the telescopic airbag 61 is stretched, so that negative pressure is generated in the air guide cover 6. Under the action of the negative pressure, the outside air enters the telescopic airbag 61 through the air guide cover 6 and the air delivery pipe 62;

[0040] When the mold needs to be opened, the cylinder 51 can be started to drive the mounting plate 5 to move upward, and at the same time drive the movable mold to separate from the fixed mold and automatically open the mold upward. In the process of the mounting plate 5 and the movable mold moving upward, the telescopic airbag 61 is squeezed so that the air inside it is blown to the product in the fixed mold through the air pipe 62 and the air guide cover 6, which can cool the product after the mold is opened again, and the residual heat on the product is taken away by the flowing air, so as to avoid residual heat on the product after the mold is opened, which can reduce the risk of product deformation, thereby improving product quality;

[0041] And in the process of the mounting plate 5 and the movable mold moving upward, the vertical plate 74 and the arc block 75 are also driven to move upward, and multiple arc blocks 75 slide over the cam 73 in turn, and the cam 73 and the air guide cover 6 are driven to move through the arc block 75. When the cam 73 is separated from the vertical plate 74, the air guide cover 6 is restored to its initial position through the spring 63. Through the cooperation of the spring 63 and multiple arc blocks 75, the reciprocating swing of the air guide cover 6 can be realized to expand the blowing range of the air guide cover 6, so that the flowing air acts evenly on the product, thereby further improving the heat dissipation effect on the product.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
