Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold for injection molding and encapsulating an inner bone model of a figurine. Background Art

[0002] With the rapid development of the action figure industry, the requirements for action figure quality and production efficiency are increasing. Injection molding and overmolding molds used for action figure endoskeleton models have gradually become a research hotspot. Action figure endoskeleton models are usually made of solid materials to support the overall structure. Through mold making, not only can the strength and stability of the action figures be improved, but also a higher aesthetic appearance can be achieved.

[0003] A Chinese patent application No. N202322606106.3 discloses a mold for injection molding of an inner bone model of a hand-made figure. The key points of its technical solution are: 1. By setting a fixed groove inside the slide groove and cooperating with a fixed rod, when the mold body is placed on the placement table, the fixed rod is rotated to release the connection between the fixed rod and the fixed groove. At this time, the pressure block is pulled upward to make the two fixed blocks on the placement table contact with the two ends of the mold body. At this time, the pressure block is released. Under the action of the first spring, the pressure block moves downward until the pressure block contacts the fixed block. At this time, the fixed block is adjusted to fix the two ends of the mold body. At this time, the fixed rod is rotated to make The fixing rod is threadedly connected to the fixing groove closest to the pressure block. At this time, the fixing rod limits the movement of the pressure block, and the pressure block limits the movement of the fixed block, thereby avoiding a reduction in the stability of the fixed block on the mold and affecting the use of the mold; 2. By setting a rotating rod inside the rotating groove and cooperating with the circular groove, due to the different thicknesses of the two fixed block bodies on different placement tables, sometimes when the pressure block and the fixed block are fitted together, the fixing rod is rotated and connected inside the fixed groove and cannot fit with the pressure block. At this time, the rotating rod is rotated so that one end of the rotating rod enters the inside of the circular groove so that the rotating rod is against the pressure block, which is convenient for cooperating with the first spring to increase the stability of the pressure block fixing the fixed block.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the staff are making the inner skeleton of the hand-made figure, the positioning hole of the upper mold will make reciprocating motion on the arc surface of the positioning rod during the production process of the inner skeleton of the hand-made figure, and the arc surface of the positioning rod will be worn due to long-term movement, affecting the positioning accuracy of the upper mold, resulting in errors and a decline in quality during the production process of the inner skeleton of the hand-made figure; therefore, in response to the above problems, a mold for injection molding and encapsulation of the inner skeleton model of the hand-made figure is proposed.

Pulling the elliptical plate 407 to slide on the arc surface of the connecting rod 406, the elliptical plate 407 drives the insertion rod 408 to move until the insertion rod 408 is out of the limit groove of the slide plate 405, so that the staff can regularly replace the lubricating pad 404 to maintain the efficient lubrication effect of the lubricating pad 404. The arc surface of the connecting rod 406 is covered with a first spring 409, and the two ends of the first spring 409 are respectively fixedly connected to the elliptical plate 407 and the U-shaped frame 401.
