Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an ejector-type injection mold. Background Art

[0002] An injection mold is a tool for producing plastic products. By injecting molten plastic into the mold and undergoing pressurization and cooling, products of the required shape are formed. The injection mold consists of a high-precision mold and a mold support, and can manufacture plastic products of various shapes and sizes, such as plastic cups, plastic plates, plastic toys, automotive parts, etc.

[0003] The types of injection molding machines are mainly divided into vertical injection molding machines, horizontal injection molding machines, angular injection molding machines, and multi-mold turntable injection molding machines. The injection device and the mold clamping device of the vertical injection molding machine are on the same straight line and perpendicular to the horizontal plane. Its advantages are small floor area and convenient mold disassembly and assembly. It is widely used. At present, during the production process of the vertical injection molding machine, it is necessary to wait for the injected mold to be cooled and ejected. This process takes a certain amount of time, and workers need to wait in front of the device to take out the ejected material, which increases the operation time and the workload of the workers, thereby reducing the production efficiency.

[0004] Based on the above situation, the utility model proposes an ejector-type injection mold with a material taking function. Summary of the Utility Model

Specific embodiments

[0023] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments.

[0024] Embodiment 1

[0025] An ejection type injection mold, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, includes a base 1, a limit ring 2, a turntable 3, a rotating shaft 4, a motor 5, a mold 6, a guide seat 10, an electric push rod 11, a vacuum suction cup 12, a sliding rod 13, and a feeding hopper 14. A limit ring 2 is fixedly connected to the base 1. The turntable 3 is rotatably connected inside the limit ring 2. The motor 5 is installed on the top of the base 1. The output shaft on the lower side of the motor 5 is connected to a rotating shaft 4 through a coupling. The rotating shaft 4 is fixedly connected to the turntable 3. The number of molds 6 is two, and the molds 6 are respectively installed on the left and right parts on the upper side of the turntable 3. A demolding assembly for ejecting plastic products is provided inside the base 1. The guide seat 10 is fixedly connected to the rear side of the base 1. Symmetrically distributed S-shaped sliding grooves are opened on the guide seat 10. The electric push rod 11 is rotatably connected inside the guide seat 10. Two sliding rods 13 are fixedly connected to the left side of the telescopic part of the electric push rod 11. The two sliding rods 13 are symmetrically distributed front and back. The two sliding rods 13 are both slidably connected to the guide seat 10. A vacuum suction cup 12 is fixedly connected to the right side of the telescopic part of the electric push rod 11. The vacuum suction cup 12 is located at the right rear of the right mold 6. A vacuum air pump for controlling its air extraction and inflation is provided on the vacuum suction cup 12. The feeding hopper 14 is fixedly connected to the rear part on the right side of the base 1. The left wall of the feeding hopper 14 is in a slope shape convenient for the product to slide in.

[0026] As Figure 3 and Figure 4As shown in the figure, it further includes a demolding assembly. The demolding assembly includes a fixed sleeve 7, a top frame 8, and a cylinder 9. Fixed sleeves 7 are fixedly connected to the bottoms of both molds 6. Top frames 8 are slidably connected within both fixed sleeves 7, and the top frames 8 are also slidably connected to the adjacent molds 6. An air cylinder 9 is installed on the inner bottom wall of the base 1, and the piston end of the air cylinder 9 is directly below the right top frame 8.

[0027] When it is necessary to take out the product, first control the motor 5 to drive the rotating shaft 4 and the turntable 3 to rotate half a circle. The left mold 6 rotates to the right. Then control the piston end of the air cylinder 9 to extend upward. The piston end of the air cylinder 9 will push the top frame 8 upward. When the top frame 8 moves upward, it can push out the product to achieve demolding. After demolding, control the piston end of the air cylinder 9 to contract downward and reset. Then control the telescopic part of the electric push rod 11 to contract downward, thereby driving the vacuum suction cup 12 and the sliding rod 13 to move downward. Since the sliding rod 13 slides within the S-shaped chute of the guide seat 10, as the sliding rod 13 moves downward, the electric push rod 11 drives the vacuum suction cup 12 to rotate clockwise by 90 degrees. At this time, the vacuum suction cup 12 will be directly above the product. Control the vacuum pump to evacuate the vacuum suction cup 12, and the vacuum suction cup 12 will suck the demolded product.

[0028] Then continue to control the telescopic part of the electric push rod 11 to extend upward, thereby driving the vacuum suction cup 12 and the sliding rod 13 to move upward. The upward moving sliding rod 13 will cause the electric push rod 11 and the vacuum suction cup 12 to rotate counterclockwise by 90 degrees to reset. At this time, the vacuum suction cup 12 sucking the product is directly above the feeding hopper 14. Finally, control the vacuum pump to release the air from the vacuum suction cup 12, and the product will fall into the feeding hopper 14, and the automatic material taking is completed. In summary, first, rapid demolding is achieved through the air cylinder 9 and the top frame 8, and then through the electric push rod 11, the vacuum suction cup 12, the sliding rod 13, and the S-shaped chute on the guide seat 10, the demolded product can be automatically taken out from the mold 6, which reduces the operation time and the workload of the staff, thereby improving the production efficiency.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, as Figure 1 、 Figure 7 and Figure 8 shown, it further includes a mounting plate 15, a buffer belt 16, and a gravity block 17. The mounting plate 15 is fixedly connected to the feeding hopper 14. Seven buffer belts 16 are fixedly connected to the bottom of the mounting plate 15, and gravity blocks 17 are fixedly connected to the lower parts of the seven buffer belts 16.

[0031] When the product falls into the feeding hopper 14, the product will slide to the right along the slope of the feeding hopper 14. The product will impact the buffer belt 16 and the gravity block 17, causing the buffer belt 16 to drive the gravity block 17 to swing to the right. When the product passes over the buffer belt 16, under the action of the self-gravity of the gravity block 17, the gravity block 17 drives the buffer belt 16 to swing back to the original position to the left. As the buffer belt 16 and the gravity block 17 continuously swing left and right, they will absorb and disperse the energy of the impact of the product, thereby reducing the direct impact force between the products. In summary, through the buffer belt 16 and the gravity block 17, buffering and shock absorption are provided to reduce the damage degree of the products when they impact each other, thereby improving the quality of the products.
