Method for making shoe mold and shoe making mold made

The invention relates to the manufacturing technology of the shoe making mold, in particular to a method for manufacturing a shoe making mold and a shoe making mold made thereof, which utilizes the manufacturing technology of the laminated manufacturing technology to save production time and material cost.

In the footwear industry, shoemaking dies are required for the production of each pair of shoes. The traditional shoe making method is to cut the metal block through a computer numerical control machine tool (CNC) to complete the shoe mold. However, shoe molds are often designed with many patterns, bumps or grooves. The overly complex model structure not only causes the computer numerical control tool to be machined for a long time, but also prone to the problem of machining dead angle that cannot be processed by the machine tool. After processing and trimming the corners, increasing the manufacturing time, the demand for short-term mold replacement will not be met. Moreover, the traditional shoe-making molds that are processed using bulk materials tend to have high material costs and are also disadvantageous for shoe cost control.

Therefore, for the manufacture of shoe molds, it is still an object to be improved to avoid the occurrence of machining dead angles and to reduce the molding materials, and how to quickly replace the molds for injection molding.

In view of the foregoing problems, the main object of the present invention is to provide a method for manufacturing a shoe making mold, which directly manufactures a shoe mold by using a laminated manufacturing technique, thereby avoiding processing The dead angle also achieves the effect of reducing the molding material. In addition, it is also possible to save the mold making time to meet the need to change the mold in a short time.

In order to achieve the above object, the present invention provides a method for manufacturing a shoe mold, comprising the steps a), using a computer, the computer storing a computer-aided design software, and operating the computer-aided design software through the computer to generate a digital shoe mold; b) forming a shell-shaped shoe body by the multi-layer shoe mold through a laminated manufacturing technique, the shell-shaped shoe mold body having a plate body, the shell-shaped shoe mold body forming a cavity on one side of the plate body, and On the other side of the plate body, a pair of convex portions corresponding to the cavity shape are formed at the relative positions of the cavity; and step c), the shell-shaped shoe mold body is fixed on a frame body, and the convex portion is placed In the inner space of the frame; and in step d), a mold core is disposed and fixed to an upper cover, and the mold can be moved in and out of the mold cavity by the upper cover.

In addition, the present invention also provides a shoe mold comprising a shell-shaped shoe body having a plate body, the shell-shaped shoe body forming a cavity on one side of the plate body, and The other side of the plate body forms a pair of convex portions corresponding to the cavity shape at the relative positions of the cavity; the shell-shaped shoe mold body is fixed to a frame body, and the convex portion is placed in the inner space of the frame body And a mold core fixed to an upper cover, and the mold can move in and out of the mold cavity by the upper cover.

It should be noted that, in the present invention, the laminated manufacturing technology is a three-dimensional printing technique.

In addition, a filler may be added to fill the frame, and the filler contacts the convex portion.

Furthermore, in order to stably fix the shell-shaped shoe mold body to the frame body, the shell-shaped shoe mold body extends a fixing post to the convex portion. The cover is attached to the frame. A plurality of fixing members are fixed to the fixing post to lock the lower cover to the frame.

Figure 8 is a perspective view of an embodiment of the present invention showing a shoe mold.

Referring to Figure 1, the present invention provides a method of making a shoe mold. In the method of making a shoe mold:

In step a), a computer 11 is first prepared, and the computer 11 stores a computer aided design software 111. The user operates the computer 11 and operates the computer aided design software 111 through the computer 11 to generate a digital shoe mold 12.

Next, in step b), the user creates the shell mold body 14 by the additive manufacturing technique 13 (Additive Manufacturing). In the embodiment, the laminate manufacturing technique 13 is a three-dimensional printing technique. Since the laminated manufacturing technique 13 utilizes the digital shoe mold 12, the shell-shaped shoe body 14 is produced by stacking discrete materials (liquid, powder, wire, sheet, plate, block, etc.) layer by layer, which is a bottom-up (bottom-up) The manufacturing technology of material stacking, because of the layered stacking material, it can avoid the processing dead angle compared with the traditional computer numerical control machine tool.

The shell-shaped shoe body 14 has a plate body 141. The shell-shaped shoe body 14 defines a cavity 143 on one side of the plate body 141, and on the other side of the plate body 141, the cavity 143. The relative position forms a convex portion 144 corresponding to the shape of the cavity 143.

In step c), the shell-shaped shoe mold body 14 is fixed to a frame body 15, and the convex portion 144 is placed in the inner space of the frame body 15.

And, in step d), a mold core 16 is disposed and fixed to an upper cover 17, and the mold core 16 can be moved in and out of the mold hole 143 by the upper cover 17.

The shoe making mold is completed by the above method, and the manufactured shoe mold can be made by moving the upper cover 16 to allow the mold core 17 to enter the cavity 143 and then injecting the sole material into the sole.

It should be particularly noted that the term "shell" as used herein refers to a form having a uniform thickness. Also, step d) can be completed before step a), step b) or step c), without a prioritized relationship.

Referring to Figures 2-5, the present invention provides a shoe mold comprising a shell-like shoe body 14 having a plate body 141. The present invention is formed on one side of the plate body 141 by a lamination manufacturing technique. A cavity 143, and on the other side of the plate 141, the relative positions of the cavity 143 form a pair of convex portions 144 which are in the shape of a cavity.

Referring to FIG. 6, the shoe mold further includes a mold core 16 and is fixed to an upper cover 17, and the mold core 16 can be moved by the upper cover 17.

Referring to Figures 6-8, the shoe mold of the present invention comprises a shell-like shoe body 14, a mold core 16 and an upper cover 17.

Further, the shell-shaped shoe mold body 14 is fixed to one side of a frame body 15, and the convex portion 144 is placed in the interior of the frame body 15. The mold core 16 is fixed to the upper cover 17, and the mold core 16 can move in and out of the mold hole 143 by the upper cover 17. The cover 19 is formed on the other side of the frame 15 and the upper and lower sides of the frame 15 are formed on the shell-shaped shoe body 14 , and then the upper cover 17 is covered on the shell-shaped shoe body 14 to complete the present invention. The shoe mold proposed by the invention. It is worth noting that unlike the conventional mold, the present invention proposes a multi-component mold for the user to quickly change the mold depending on the type of product.

It should be noted that, in the present embodiment, due to the characteristics of the laminated manufacturing technology 13, the manufacturing method of the shoe mold of the present invention can directly produce the shell-shaped shoe body 14, avoiding the processing of dead angles and saving materials. However, the physical strength of the shell-shaped shoe body 14 is less resistant to solid shoe molds, and the material used in the laminate manufacturing technique 13 is difficult to be as stable as a block, so that the shell-shaped shoe body 14 is put into production. In the process of the sole, it may be damaged due to insufficient strength of the material to resist the strength of the process. Therefore, the present invention further fills the frame 15 with a filler (not shown), such as sand, and the filler 18 contacts the convex portion 144 to assist in supporting the shell-shaped shoe body 14. The pressure of the shell-shaped shoe body 14 can be prevented from being damaged during the process.

It should be noted that the shell-shaped shoe body 14 extends from the protrusion 144 to a fixing post 145. The cover 19 is attached to the frame 15. The plurality of fixing members 21 fix the lower cover 19 and the fixing post 145, thereby stably fixing the lower cover 19 to the frame body 15.
