[0007] The utility model provides the following technical solutions:

[0008] A hot melt adhesive cooling molding device, comprising:

[0009] A cooling box, wherein a cooling cavity for accommodating cooling water is provided inside the cooling box, two openings for inserting ice cubes are provided on the top of the cooling box, both of the openings are connected to the cooling cavity, and a bayonet connected to the cooling cavity is provided on the top of the cooling box;

[0010] A heat dissipation cooling mechanism is arranged at the top of the cooling box and is used for dissipating heat and cooling the top range of the hot melt adhesive raw material;

[0011] The movable positioning mechanism is arranged on both sides of the cooling box for moving and positioning the position of the cooling box.

[0012] In a possible design, the heat dissipation cooling mechanism includes two movable racks, four cooling fans, two threaded blocks and two movable blocks. The four cooling fans are divided into two groups. Each group of cooling fans is fixedly installed on the bottom side of the inner wall of each movable rack. Each threaded block and movable block are respectively fixedly arranged on the bottom side of the movable rack. The top side of the cooling box is respectively provided with a threaded groove and a movable groove for sliding connection of the threaded block and the movable block.

[0013] In a possible design, a motor is fixedly installed on one side of the cooling box, and the output end of the motor passes through one side of the cooling box and extends to the inside of the threaded groove. A bidirectional screw is fixedly provided on the output end of the motor through a coupling, and the outer wall of the bidirectional screw is connected to the internal threads of the two threaded blocks. A guide rod is fixedly provided between the two sides of the inner wall of the movable groove, and a guide hole is provided inside each of the movable blocks and is slidably connected to the outer wall of the guide rod.

The two fixed blocks are respectively fixed on both sides of the cooling box, and the bottom end of each threaded rod is rotatably connected to the top side of the fixed block through a rotating shaft. The interior of each threaded plate is threadedly connected to the outer wall of the threaded rod.

[0015] In a possible design, the four sliding rods are divided into two groups, the top end of each group of sliding rods is fixed to the bottom side of each threaded plate, each pulley is fixedly installed on the bottom end of the sliding rod, and two fixing plates are fixedly provided on the top side of each fixed block, and a sliding hole is opened inside each fixing plate for sliding connection to the outer wall of the sliding rod.

[0017] In a possible design, a drain pipe connected to the cooling chamber is fixedly provided on one side of the cooling box, and a valve is provided on the outer wall of the drain pipe.

[0018] In the present application, when in use, the mold box is first placed on the top of the cooling box through the bayonet, so that the bottom of the mold box is inside the cooling chamber, which is convenient for subsequent cooling.

[0020] After a period of heat dissipation and cooling, the hot melt adhesive raw material is gradually cooled and formed in the mold box. At this time, the motor and the cooling fan can be turned off. After cooling is completed, if you need to replace the cooling water or discharge excess water, you can open the valve on the drain pipe on one side of the cooling box to drain the water in the cooling chamber, and then you can re-add ice cubes for the next round of cooling operation. Finally, when you need to move the cooling box, you can manually rotate the threaded rod to drive the threaded plate connected to the outer wall thread to move up and down, and then the threaded plate can drive the sliding rod and pulley fixed at the bottom to move accordingly. When the pulley drops to contact the ground, the cooling box can be easily pushed or dragged to the designated position by the pulley. After reaching the designated position, rotate the threaded rod in the opposite direction to lift the pulley. The cooling box is supported by the bottom fixed block and stably fixed on the ground, which makes it convenient to move the device as a whole according to different needs and improves its applicability.

[0021] In the utility model, the hot melt adhesive cooling molding equipment can inhale the hot air above the mold box through the heat exhaust cooling mechanism and accelerate the exhaust through the fan blades to form a local airflow circulation, and perform heat exchange through the low temperature environment in the cooling box, which is beneficial to accelerate the cooling process of the hot melt adhesive raw material and effectively reduce the surface temperature of the hot melt adhesive raw material;

[0022] In the utility model, the hot melt adhesive cooling and molding equipment can easily push or drag the cooling box to a designated position through a pulley through a mobile positioning mechanism, and stably fix it on the ground, thereby achieving the effect of conveniently moving the entire device according to different needs;
