DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The power of the sliding mechanism 10 is realized by the sliding cylinder 12, so that the sliding mechanism 10 can be driven by the sliding cylinder 12 to enter and exit between the upper mold 20 and the lower mold 30, so as to achieve the purpose of being able to move the sliding mechanism 10 to the outside of the upper mold 20 and the lower mold 30 to dock with the assembly mechanism 40. The sliding mechanism 10 needs to take out the injection molded product, so after the product is injection molded and the upper mold 20 is opened, the product needs to be left on the sliding mechanism 10. By setting the sliding mechanism 10 with a product side profiling block 14 and a product bottom profiling block 15, the side and bottom of the injection molded product can be removed after the upper mold 20 is opened. The product is in contact with the lower mold 30 on only one side, so when the slide mechanism 10 is pushed, the product can be taken out along the slide mechanism 10. On this basis, the product side profiling block 14 and the product bottom profiling block 15 on the slide mechanism 10 can be separated by a secondary demoulding method, so that the product is only left on the product bottom profiling block 15 so that it can be docked with the assembly mechanism 40 and discharged upward without being interfered by the product side profiling block 14. Through this arrangement, the assembly mechanism 40 can be integrated on the lower mold 30, so that the product can be directly assembled in the assembly mechanism 40 after being separated from the product bottom profiling block 15.

[0029] In order to more clearly illustrate the implementation method of the sliding mechanism 10 of the utility model; the utility model sets up a mold integrated with an assembly mechanism, including the sliding mechanism mentioned above, and also including a lower mold 30, an upper mold 20 and an assembly mechanism 40, a molding area and an assembly area are set on the lower mold 30, the upper mold 20 and the molding area of ​​the lower mold 30 are molded together, the assembly mechanism 40 is installed on the assembly area of ​​the lower mold 30, the track slide 11 is set on the lower mold 30 and spans the molding area and the assembly area, when the product side profiling block 14 and the product bottom profiling block 15 move to the molding area and dock with the upper mold 20 and the lower mold 30, a mold cavity for molding the product is formed between the upper mold 20, the lower mold 30, the product side profiling block 14 and the product bottom profiling block 15, when the product bottom profiling block 15 moves to the assembly area, the product bottom profiling block 15 serves as a feeding end and docks with the assembly mechanism 40.

[0030] By extending the lower mold 30 to set up an assembly area, the lower mold 30 has both a molding area and an assembly area. The molding area is docked with the upper mold 20 to achieve injection molding of the product, and the assembly area is docked with the assembly mechanism 40 to achieve automatic entry of the product into the assembly mechanism 40 for assembly after molding. Through this setting, the purpose of both product molding and product assembly can be achieved on one mold, thereby greatly reducing the assembly cost of labor or equipment, reducing the transportation cost of the product, and reducing the floor space occupied by the equipment, so that the production and assembly efficiency of the product can reach a higher level of improvement.

[0031] In order to more clearly describe that the molding and assembly of the product are all realized on the same mold, in this embodiment, the product is further explained by selecting the link 1 of the drag chain.

The assembly mechanism 40 is set to include a link assembly seat 41 and a power pushing mechanism 42 connected to the link assembly seat 41. In addition, an ejection mechanism 50 is set, so that when the link 1 is moved to the position of the assembly area by the sliding mechanism 10, the ejection mechanism 50 pushes the link 1 upward into the link assembly seat 41, and an assembly path is set on the link assembly seat 41. The chain link 1 is docked with the power driving mechanism 42, so that the chain link 1 is compressed by the power of the power driving mechanism 42 after entering the assembly path. When the next chain link 1 enters the assembly path again, it can be pushed by the ejection mechanism 50 to drive the next chain link 1 to be buckled and assembled with the compressed chain link 1. After the assembly is completed, the power driving mechanism 42 will release the chain link 1, and then the assembled chain link 1 will be gradually pushed upward by the ejection mechanism 50, and finally it can be ejected along the assembly path to the outside of the chain link assembly seat 41, so as to achieve the purpose of realizing the molding of the chain link 1 and the assembly of the drag chain on one mold.
