Description

Technical Field

[0001] This utility model relates to an injection molding machine, specifically a luggage trolley injection molding machine, belonging to the field of luggage trolley production technology. Background Technology

[0002] A rolling suitcase is a type of luggage with a pull handle and wheels. It is widely used because of its convenience. Rolling suitcases are also divided into single-tube and double-tube pull handles, depending on the pull handle itself. The tubes of the pull handle are also divided into square tubes and round tubes, which makes it easier to drag while walking and greatly reduces the burden.

[0003] A luggage pull rod production molding device disclosed in Chinese Patent Application Publication CN218227712U, through the cooperation of a lower mold, an upper mold, a base plate, a shell, a straight plate, a vertical cylinder, a vertical plate, a hydraulic cylinder, a horizontal plate, a plate body, and a demolding mechanism, allows the device to be used by pulling the horizontal bar to the left, causing it to disengage from the groove of the vertical bar. A spring then moves a square plate upwards, which in turn moves a push rod upwards, thus ejecting the molded pull rod. This facilitates the removal of the injection-molded pull rod by the operator. Furthermore, the device's operation is facilitated by the coordination of the lower mold, upper mold, base plate, shell, straight plate, vertical cylinder, vertical plate, hydraulic cylinder, horizontal plate, plate body, and cooling structure. During operation, a motor drives a lead screw to rotate, which in turn moves a horizontal block up and down. The horizontal block then moves a fan up and down, thereby cooling the lower mold. This eliminates the need to wait for the injection molding to cool naturally, shortening production time and improving work efficiency.

[0004] In the above patented solutions, the molded pull rod is pushed out to facilitate the removal of the pull rod after injection molding by the staff. However, this process requires manual operation, making it difficult for the molded pull rod to be automatically ejected. Furthermore, the spring will become fatigued after long-term use, thus affecting its ejection. At the same time, the lower mold is cooled by moving the fan up and down. This method of cooling is inefficient and requires a long cooling time.

[0005] Therefore, a luggage trolley injection molding machine is proposed here. Utility Model Content

[0006] This utility model proposes a luggage trolley injection molding machine that can automatically eject the injection-molded trolley and also rapidly cool it down, reducing the cooling time of the trolley.

The two support blocks are fixed to the left and right sides of the upper mold, respectively. A limit block is fixed to the top of the sliding rod, and the limit block is located above the support block.

[0009] The cooling assembly includes a water tank and a refrigeration device fixed on the upper surface of the base and a cooling groove opened on the lower mold. The refrigeration device is installed on the water tank, and a water pump is installed on the upper surface of the water tank. The input end of the water pump is connected to the water tank through an inlet pipe, and the output end of the water pump is connected to the cooling groove through an outlet pipe.

[0010] Furthermore, multiple support pillars are fixed to the upper surface of the base, and a top plate is fixed to the top of each support pillar.

[0011] Furthermore, a hydraulic rod is fixed to the inner wall of the hole in the middle of the top plate, and the bottom end of the hydraulic rod is fixed to the upper surface of the upper mold.
