Description

Forming mold of unfolding comb tooth element

This creation is about a molding die for an unfolding comb tooth element, especially a molding die that can directly produce an unfolding comb tooth element.

It is known that the existing comb structure usually includes a dentition part and a handle part. The common problem is that in order to obtain the holding strength of the handle, it is necessary to use a hard material to avoid bending deformation due to tangled hair. The dentition part and the grip part are formed, causing the dentition part to be hard and easy to scratch the scalp and remove the hair. Moreover, if the tooth tips of the dentition form a needle-point shape, the tooth tips are very easy to puncture the scalp when combing the hair, which is potentially dangerous. In addition, if the dentition part of the comb is cut or abraded, the cutting surface will inevitably be produced and lack smoothness, resulting in the peak angle of the dentition part, and it is easy to pull out the hair when the comb is loose and cause damage. Furthermore, if the surface area around the teeth of the comb is large, oil and dirt will be attached to the comb when combing the hair, causing the dirt to be attached to the combed hair the next time it is used. On the hair. In addition, the dentition part of the comb lacks elasticity. During the combing process, the hair is easily tangled in the dentition part. At this time, if the comb is pushed again, the tangled hair will easily be pulled out. In view of the above-mentioned problems, the creators have carefully developed a tower comb element, which can form a more comfortable and safe comb structure to improve the above-mentioned conventional comb problems. However, the inventor is not complacent with this, and still keeps the spirit of excellence in order to further shorten the comb manufacturing process and improve the convenience of comb manufacturing.

In order to solve this problem, the present creation provides a mold for forming an unfolding comb tooth element, including: a mold core, including a tip and an enlarged portion formed at one end of the tip, and a horizontal plane is formed between the tip and the enlarged portion , The surface of the mold core forms a first mold cavity, and the first mold cavity spirally surrounds the surface of the mold core. The first mold cavity further includes an entrance end, two separable modules, each including a mating surface and A mold core cavity formed on the mating surface. The mold core cavities of the two modules are combined to conform to the cross-sectional shape of the mold core. The surface of each mold core cavity corresponds to the first mold cavity to form a second mold cavity. The corresponding entrance end of the module forms an inlet. When the mating surfaces of the two modules are close to each other, the mold core is accommodated between the two mold core cavities, and the combined shape of the two mold core cavities conforms to the mold core .

The molding die of this creation can quickly produce good quality comb elements.

In the forming mold of the expandable comb tooth element, the enlarged portion of the mold core further includes an upper arc surface formed above, and the sections of the first and second mold cavities corresponding to the upper arc surface form an arc shape .

In the molding die of the expandable comb tooth element, the cross-sectional shape of the enlarged portion is a fan shape, and the cross-sectional shape of the tip portion is an inverted triangle.

This creation also provides a comb-tooth element molded by a molding die, which is formed into a spiral shape from a flexible linear material through a molding die. The molding die includes a mold core that includes a tip and is formed at one end of the tip. An enlarged part of the, forming a horizontal plane between the tip and the enlarged part, the surface of the mold core forms a first mold cavity, and includes two separable modules, each including an opposing surface and a surface formed on the opposing surface A mold core cavity, the mold core cavities of the two modules are combined to match the cross-sectional shape of the mold core. The surface of each mold core cavity corresponds to the first mold cavity to form a second mold cavity, and the elastic linear material passes through the The first and second cavities of the forming mold are processed into a spiral-shaped comb tooth element package It includes a plurality of fan-shaped assembling parts, and a comb part formed in a triangle below each assembling part, the maximum width of the assembling part is greater than the maximum width of the comb part, and a horizontal section is formed between each assembling part and each comb part, The comb parts are separated from each other to form a gap between any adjacent two.

The design of the upper arc of the comb tooth element made by the mold of this creation and the horizontal section provides good elastic deformation. In detail, when the comb element is used to comb the hair, the comb part presses the human scalp to generate pressure, making the upper arc section It is easy to produce bending elastic deformation, and the horizontal section produces bending elastic deformation, so that when combing the hair, the comb tooth element will not exert too much pressure on the scalp and cause the scalp to be injured.
