Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of injection molding machine structure, specifically a cooling structure for an injection molding machine used in the production of plastic storage boxes. Background Technology
[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity, where it is molded and cooled. Some modern injection molding machines have cooling structures on the molds to accelerate the molding efficiency of the plastic products inside the mold.
[0003] An existing injection molding machine cooling structure, such as the one described in patent publication number CN220095444U, features a cooling mechanism on one side of the outer mold. Multiple cooling plates absorb heat from the inner wall of a connecting notch, facilitating the cooling of water in a water tank. A water pump then pumps water from the tank into a flow channel, allowing the cooled water to circulate rapidly and quickly cool the outer mold. The multiple flow channels on the bonding plate reduce the water's flow time, preventing a significant temperature rise and ensuring effective cooling. This enhances the cooling effect and efficiency of the cooling structure, improving its practicality. Furthermore, removing multiple fixing bolts allows for easy disassembly and separation of the cooling mechanism and the outer mold, facilitating replacement or repair of the cooling mechanism.
[0004] However, because the conveying unit is located on one side of the outer mold, the device relies solely on cooling plates for water cooling, resulting in low efficiency and poor practicality. Utility Model Content

This structure features an external large water tank, which allows for better water circulation, faster water cooling, and greater energy efficiency, thus improving practicality.

A water-cooled bonding frame is provided on one side of the injection mold body. The output end of the water-cooled bonding frame is connected to the main port of the branch tee via the output main pipe. The two branch ports of the branch tee are respectively connected to the input ends of a set of fine-tuning drain heads via a set of output branch pipes. The middle and rear parts of the top left and right sides of the large water storage tank are respectively connected to the middle part of the bottom side of a set of fine-tuning drain heads via a set of drain head support frames. The water pump is fixed to the lower front side of the large water storage tank, and the input end of the water pump is connected to the large water storage tank. The output end of the water pump is connected to the input end of the water-cooled bonding frame via an inlet pipe, and a filter mechanism is provided at the connection between the inlet pipe and the water-cooled bonding frame. A blower mechanism is also provided on the front side of the top of the large water storage tank.
[0008] Preferably, the filtration mechanism includes an inner threaded sleeve, a filter screen, and an outer threaded frame. The input end of the water-cooled bonding frame is connected to the inner side of the outer threaded frame, and the output side of the water inlet pipe is connected to the inside of the inner threaded sleeve. The filter screen is detachably installed inside the inner threaded sleeve, and the inner wall of the inner threaded sleeve is detachably screwed to the outer wall of the outer threaded frame.
[0009] Preferably, it also includes a screw-on handle, wherein one side of the outer end of the internal threaded sleeve is connected to the inner side of the screw-on handle.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a cooling structure for an injection molding machine used in the production of plastic storage boxes, which has the following beneficial effects: The injection molding process for plastic storage boxes involves the production of these boxes within the injection mold body. When cooling is required, a water pump draws some of the cold water from a large water tank through the inlet pipe. After being filtered by a filtration mechanism, the water circulates within a water-cooled bonding frame to cool the inside of the injection mold body. The water is then output through the main outlet pipe, branched at a tee, and delivered to two sets of outlet pipes for further cooling and discharge through the finer drain heads. With the finer drain heads fixed by corresponding drain head support frames, the discharged water can fully contact the air for heat dissipation and is then returned to the large water tank for further cooling and circulation through a blower mechanism. The external large water tank allows for better water circulation, resulting in faster cooling, greater energy efficiency, and improved practicality. Attached Figure Description
