Description

Forming mold for manufacturing tower comb tooth element

The invention relates to a molding die for manufacturing tower comb teeth elements, in particular to a molding die which is convenient for shaping and producing tower comb teeth elements.

It is known that the existing comb structure usually includes a dentition part and a grip part. The common problem is that in order to obtain the firmness of the grip, no bending deformation is caused by the tangling of the combing hair, that is, it must be hard The material is integrally formed into the dentition part and the grip part, which causes the dentition part to be hard and easy to scratch the scalp and pluck hair. Moreover, if the tips of the teeth in the dentition form needle-like shapes, the tips of the teeth can easily puncture the scalp when combing the hair, which is potentially dangerous. In addition, if the tooth rows of the comb structure are processed by cutting or abrasion, the cutting surface will lack smoothness, resulting in a peak angle of the tooth rows, and it is very easy to pull out the hair when the comb head is loose and cause damage. Furthermore, if the surface area around each tooth of the comb is large, it is easy to attach oil and dirt to the hair when combing the hair, causing the dirt to adhere to the comb to be combed next time. On the hair. In addition, if the dentition part of the comb lacks elasticity, during the combing process, the hair is easily entangled in the dentition part. At this time, if the comb is pushed again, the entangled hair is easily pulled out. In view of the above problems, the creator has carefully developed a tower comb element and tower hair straightener made of hard steel wire, thereby forming a more comfortable and safe comb structure, which can effectively improve the above problems .

The heating liquid is heated to be softened and easily deformed (the temperature varies according to the material), so that the processing material 68 easily moves along the space formed by the forming groove 45 and the outer ring groove 30, and the processing material 68 The starting end 32 of the outer ring groove 30 of the above mold core 20 extends along the outer ring groove 30 to the end 34 of the outer ring groove 30 (as shown in Figure 3), until the end of the processing material 68 is displaced to the die When the terminal of Ren 20 is 34, the respective flow channel 52 of each module 38 is filled with cooling liquid to cool the processing material 68 and finalize it. After opening the second module 38, the processing material 68 can be removed. It is worth mentioning that The processing material 68 around the outer side of the mold core 20 can be directly removed from the mold core 20 because of its elasticity. The removed processing material 68 is formed into a tower comb element including a plurality of parallel comb teeth 78 70 (as shown in Figure 5). The shape of the tower comb element 70, that is, the blunt portion 26 corresponding to the mold core 20 forms a top frame portion 72 and a frame edge 76, and the tip portion 28 corresponding to the mold core 20 forms a comb tooth portion 74. And the side convex portion 27 corresponding to the mold core 20 forms a protruding wing 80, the outer end groove 30 corresponding to the mold core 20 begins to form a first hook 82, and corresponds to the outer ring groove 30 of the mold core 20 The terminal 34 forms a second hook 84. The unfolding of the tower-shaped comb element 70 first places the top frame portion 72 in a grooved body (not shown in the structural diagram of the invention), and hooks the groove by the first hook 82 or the second hook 84 Shape, and you can grasp the convex wings 80 of the tower comb element 70 by hand to expand in a lateral direction (as shown in Figure 6), by which the comb teeth 78 of the comb teeth portion 74 can be used for hair combing operation .

The present invention is characterized in that, by means of the opening and closing matching module 36 and the mold core 20 structure, the heated and softened processing material 68 can be quickly extended into the outer ring groove 30 on the periphery of the mold core 20 for shaping and positioning. Therefore, the tower-shaped comb-tooth element 70 can be manufactured conveniently and quickly, thereby manufacturing a comb that is light and elastic and easy to comb hair without tangling hair for consumers to choose.

The basic teachings of the present invention have been explained in the preceding paragraphs. For those with ordinary skills in the art, many extensions, changes or conversions will be obvious to others, for example, on the blunt part 26 of the mold 20 If no two-sided convex portion 27 is provided, and the two first acupuncture points 42 of the second module 38 do not have two-sided deep concave portions 44, so that the frame edge 76 of the tower-shaped comb tooth element 70 that is shaped out does not have the convex wings 80, It is also possible for the user to grasp the frame edge 76 of the top frame portion 72 by hand to expand along the lateral direction, and the comb teeth 78 after the comb teeth portion 74 is expanded can be used to comb the hair. This is known to those of ordinary skill in the field.
