Abstract

PURPOSE:To lessen the number of molds and the frequency of molding work while reducing the burr removing work by making a portion for molding the body of a doll communicate parts for molding arms or legs through a connecting wall and a fitting projection. CONSTITUTION:In a mold 1 for slush molding, parts 5 for molding arms are provided successively with a portion 6 for forming a fitting projection through a portion 7 for molding a fitting groove. This portion 6 communicates with a portion 3 for molding the opening for fitting arms at a part 2 for molding a body through a connecting wall 8. Likewise, a part 9 for molding legs is provided successively with a portion 10 for forming a fitting projection through a portion 11 for molding a fitting groove. The portion 10 communicates with a portion 4 for molding the opening for fitting legs at the part 2 for molding the body through a connecting wall 12. The body, arms and legs can be turned out by cutting the parts molded with the connecting walls 8 and or off a molding made with the mold 1 using a knife or the like.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mold for slush molding, and particularly to a mold for slush molding for forming a doll having a structure in which arms and legs are rotatably fitted to a body. It is related to molds.

[Prior art]

Conventionally, when slush molding a hollow vinyl chloride doll with a structure in which the arms and legs are rotatably fitted to the torso, separate molds must be prepared to mold the two torso legs and the arms. There wasn't. Therefore, also the torso,
The molding of the nine arms and legs also had to be done separately. Moreover, each of the separately molded torso, arms, and l1I41 has a t'k mark at the open end as shown in FIG.
Since gPl bars IJ 16, 17, 18, and 19 are formed, remove them with a knife, etc.! 1l114y,
I couldn't bear the hassle. Furthermore, if the torso and nine arms and legs were molded separately, there were drawbacks such as uneven molding or dispersion of each part.

[Purpose of the invention]

The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a slush molding mold for doll molding, which can reduce the number of molds, the number of molding operations, and the amount of thatch to remove. It is.

[Structure of the invention]

The present invention provides a slush molding mold for molding a doll having a structure in which at least one of the arms or legs is rotatably fitted to the torso. At the opening 1'' portion corresponding to the portion where either one of the legs is molded, there is an oni 4 portion that communicates with the portion where the fitting protrusion is completely molded and through the portion where the connecting wall is molded.

[For production]

This invention provides a method for forming a part for forming a torso and a part for forming at least one of the arms or legs at corresponding openings, through a part for forming a fitting protrusion and a part for forming a connecting wall. Since they are connected, it is possible to mold the torso and the arms and legs, or the torso and the arms or legs, in the second molding operation, and by cutting out the connecting wall that connects the torso and the arms or legs from this molded product. Each component is completed.

[Fu example]

An embodiment of the slush molding mold according to the present invention will be described based on the drawings. The slush molding mold 1 includes a portion 2 for molding a torso, a portion 5 for molding arms, and a portion 9 for molding legs. It consists of

The part 5 for forming the arm is connected with a part 6 for forming a fitting protrusion through a part 7 for forming a fitting 6. The part 6 for forming the low-rise protrusion is for forming the body. It communicates via a connecting wall 8 with a portion 3 forming an opening for arm fitting in the portion 2 . Similarly, the part 9 forming the leg is connected with a part 10 forming a fitting protrusion via a part 11 forming a fitting groove, and the part 10 forming a low protrusion is connected to the body. The part 2 which molds the leg-fitting opening is communicated with the part 4 which molds the leg fitting opening via a connecting wall 12.

If the parts formed by the connections gs and +2 are cut out with a knife or the like from the molded product formed by the mold 1, the body, arms, and legs of the doll are completed.

Although dolls have been described in the embodiments, it goes without saying that the present invention includes not only doll toys in a narrow sense, but also animal toys and robot toys.

〔effect〕

In this invention, as described above, the part for molding the torso and the part for molding at least one of the arms or legs are communicated through the connecting wall and the fitting protrusion. Not only does the number of molding operations need to be reduced, but the task of removing pars is also reduced.
