[Industrial applications]

 The present invention relates to a glove forming die for forming gloves by immersing them in a solution of synthetic resin such as vinyl chloride or rubber.

[0002]

[Prior Art]

 In the dipping method in which the mold is dipped in a solution of synthetic resin or rubber to form gloves, the process of removing the ears (unnecessary part) remaining at the glove mouth (hand entrance) and treating the edges is required. It is indispensable, and therefore the applicant of the present invention first invented a glove forming die in order to eliminate the troublesomeness of the ear removal work by the cutter in the glove manufacturing process (Japanese Patent Application No. 57-113915). That is, the mold is provided with a pointed ridge projecting in a blade shape around the mouth (hand entrance) of the mold body, and the glove body film-forming surface is provided between the ridge and the fingertip. The area between the ridges and the base edge is used as the ear surface, and the solution adhering to the apex part is locally thinned by surface tension, so that The ear portion formed on the film is peeled off from the thin film portion formed on the tip portion.

[0003]

[Problems to be solved by the device]

 However, unless the degree of adhesion between the ear film-forming surface and the ear is lowered, the peeling property of the ear is poor and the peeling work takes time, resulting in a reduction in work efficiency. Further, since the ear portion is originally an unnecessary portion, it is preferable that the amount of the attached raw material is as small as possible, but no adjustment has been made in that regard, leaving room for improvement.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to improve the ear peeling property of a glove forming mold used in the dipping method. This is to reduce the amount of the ear material deposited.

[0005]

[Means for Solving the Problems] The technical means made by the present invention to achieve the above-mentioned object is a forming die in which a pointed tip-like protrusion is provided in the mouth region of the glove body. That is, a fluorine-based coating layer was provided on the ear film-forming surface between the tip of the protrusion and the base edge.

[0006]

[Action]

 By the above technical means, the wettability of the ear film formation surface is improved by the fluorine of the coating layer provided on the ear film formation surface between the ridge and the base end edge.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a glove forming mold, which is formed in a desired hand-shaped shape with earthenware, metal or the like, and a ridge portion 5 is formed around a mouth portion 3 (hand inlet portion) of a mold body 2. The glove body A is formed on the glove body A from the ridge tip 6 to the fingertip 7 and the ear B is formed from the ridge tip 6 to the base edge 4. The ear portion film-forming surface 9 is provided, and the coating layer 10 is provided on the entire area of the ear portion film-forming surface 9.

The ridge portion 5 protrudes in a wavy shape with a pointed tip at the periphery of the mouth portion 3 (hand entrance portion) of the mold body 2, and the tip 6 of the ridge portion 5 serves as a boundary to form the film forming surface of the glove body. The mold surface 1a is divided into 8 and an ear film forming surface 9. The corrugated shape of the ridge portion 5 is an example, and the shape is not limited.

The glove main body film-forming surface 8 is formed from the ridge portion tip 6 (point portion) to the fingertip portion 7 as conventionally known.

On the other hand, the ear film-forming surface 9 is provided with a fluorine-based coating film layer 10 having a desired thickness on the mold surface 1a of the film-forming surface 9 to improve wettability (sliding property).

Here, a specific example of the fluorine-based coating layer 10 is shown below, but it is merely an example and the present invention is not limited thereto. Assembled Ni-F system surface treatment (thickness 30μm) Friction resistance (dynamic) 0.06μm (500g vertical load)

A glove molded by the molding die of the present invention may be a single glove, a flocked glove, or the like, and the edge shape, wall thickness, and the like can be changed as appropriate, and there is no limitation.

Therefore, when a desired glove is formed by the dipping method using the above-mentioned glove forming die 1, when the glove body film forming surface 8 is dipped in a desired solution, for example, a vinyl chloride solution, and pulled up. The vinyl chloride paste of the required thickness adheres as usual to form a film on the glove body A, while the ear surface film-forming surface 9 has a high wettability of the fluorine-based film layer 10 on the surface, and the amount of vinyl chloride paste adhered. Was suppressed to about 1.8g and the ear B was deposited (conventional about 2.5g, about 28% reduction).

Further, after the film formation, the ear B can be peeled easily and surely when it is peeled off manually or by an automatic ear removing mechanism provided as part of the manufacturing line.

[0016]

[Effect of the device]

 The present invention relates to a mold having a glove body having a protrusion with a pointed tip in the peripheral area of the mouth, and a fluorine-containing system is formed on the ear film forming surface between the tip and the base edge of the protrusion. Since it is a mold with a coating layer, the above-mentioned fluorine improves the wettability (sliding property) of the film forming surface of the ears, improving the peelability when peeling off the ears adhering to the mold surface The amount of the raw material that forms the ears, which are the parts, can be reduced (for example, the amount that was conventionally about 2.5g was about 1.8g, which is about 28% reduction).
