Description

Technical Field

[0001] The utility model relates to the technical field of luggage drawbar forming, in particular to high-precision luggage drawbar forming equipment. Background Art

[0002] With the continuous improvement of people's living and consumption levels, various bags have become indispensable accessories around people. Bags are a general term for bags, which are used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags and various trolley cases. Among them, trolley cases refer to suitcases with a drawbar and rollers, and the drawbar is generally processed by an injection molding machine.

[0003] For example, a forming device for a luggage drawbar with the authorization announcement number CN213107957U can drive the first shell and the second shell to approach each other and form a complete cavity through the limit plate. After the injection molding is completed, the baffle is driven upward by the output end of the electric push rod, which can drive the core plate to move upward. Under the action of the first spring, the pressure rod can be driven to reset, so that the first shell and the second shell rotate to both sides. When the core plate is pulled upward, the injection molded product will be between the first shell and the second shell. The connecting rod drives the first slide rod to push the injection molded product out. Through this structure It is conducive to rapid demoulding after injection molding, so that the demoulding efficiency is high and the demoulding effect is good. It is convenient to use and easy to operate. It is highly practical in actual use. However, during the use of the luggage tie rod forming equipment in the above-mentioned document, after the luggage tie rod forming equipment in the above-mentioned document injects raw materials into the mold, the molding equipment needs to close other components during the internal raw material molding and demoulding process. Therefore, during the mass production of luggage tie rods, the luggage tie rod forming equipment cannot continue to work due to the long waiting time, resulting in poor continuous performance and low efficiency of luggage tie rod molding production.

[0004] At the same time, during the use of the luggage tie rod forming equipment in the above-mentioned documents, since the luggage tie rod forming equipment lacks an auxiliary structure for cooling the mold, the raw materials inside the luggage tie rod forming mold in the above-mentioned documents are only cooled naturally by external air during the cooling process, and the temperature drop on the surface of the workpiece is uneven, which causes the molded tie rods to be easily damaged and cracked during the demolding process, resulting in low production accuracy of the luggage tie rod forming equipment, affecting its use.
