Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and in particular to a demoulding and ejecting device for an injection mold. Background Art

[0002] Injection molds are tools used in the plastics processing industry to give plastic products complete shapes and precise dimensions. After the product is formed, it is necessary to demold the product. At this time, an injection mold demolding and ejection device is needed. Its working principle is to use mechanical force to push the molded plastic parts out of the mold for smooth demolding.

[0003] During the use of existing injection mold demoulding and ejecting devices, these demoulding and ejecting devices fail to realize the automatic unpacking function, which means that in the process of removing the mold, the operator needs to manually open the mold box. This step not only increases the complexity of the operation, but also reduces production efficiency; in addition, after the plastic product is injection molded, both the mold and the product require appropriate cooling time to ensure stable product quality. However, the current demoulding and ejecting devices do not effectively cool the mold and the product, which may cause uneven cooling of the product, affect product quality, and may even damage the mold or product due to excessive temperature.

[0004] Therefore, in order to solve the above problems, the present application provides an injection mold demoulding and ejecting device.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0007] The present application provides an injection mold demolding and ejecting device, comprising a box body, a hydraulic cylinder is fixedly installed at the bottom of the box body, and a cooling part for cooling the molding groove is arranged on the outer wall of the box body, a push plate is fixedly installed on the top of the piston rod of the hydraulic cylinder, and an opening part for opening the box door is fixedly installed at the upper and lower ends of the top surface of the push plate, and the opening part comprises a rotating rod, a fixed block, a U-shaped rod, a first rotating shaft and a second rotating shaft, wherein the rotating rod is fixedly installed at the upper and lower ends of the top surface of the push plate, the two fixed blocks are movably arranged on the side walls of the rotating rod through the first rotating shaft, and the U-shaped rod is movably connected to the top of the fixed block through the second rotating shaft.

[0008] Preferably, the width of the inner cavity of the box body is at least greater than the distance that the left and right U-shaped rods move back to the sides.

[0009] Preferably, the box door is fixedly mounted on the top of the U-shaped rod, and the box door just closes the top of the box body when combined.

[0010] Preferably, the cooling part includes a ventilation duct, a condenser and a circulating fan, wherein both ends of the ventilation duct are fixedly connected to the left and right side walls of the box respectively, and the ventilation duct is connected to the inside of the box, and the condenser and the circulating fan are fixedly installed on the ventilation duct.

[0011] Preferably, the top ends of the left and right side walls of the box body are provided with openings for movement of the box door.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The demoulding and ejecting device of the injection mold is used in coordination with the box opening part and the cooling part. When the box is sealed, the condenser is controlled to input gas into the box through the ventilation pipe. Under the circulation action of the circulating fan, the temperature inside the box is reduced, so that the product is cooled evenly and the product quality is ensured to be stable. The hydraulic cylinder is controlled to push the push plate to move upward, and the fixed block will open to both sides around the first rotating axis.
