Abstract:
A mold apparatus with replaceable mold plates comprises mold bases, and positioning units used to position mold plates on the respective mold bases. If the positioning units are removed, the mold plates can be easily replaced in such a manner that the mold plates are made to slide along the positioning units, facilitating the replacement of the mold plates. Since the mold plates can be quickly replaced, when different products are going to be produced, it only needs to redesign new mold plates with new forming blocks, and the new mold plates can also be applied to the original mold bases as long as they are formed with the guide grooves for cooperating with the positioning portions of the positioning units, greatly reducing the production cost while producing high economic benefits.
Abstract:
An air pressure adjustable elastic body is integrally formed with an inflation/deflation module on a joining member which is formed by plastic injection molding. With the inflation/deflation module, the user can adjust the air pressure in the elastic body as desired, improving the application of the elastic body. Furthermore, since all components of the elastic body are formed by the plastic injection molding, the manufacturing procedure can be simplified, reducing the production cost while enhancing the economic benefit. In addition, since the elastic body is formed by the integral injection molding, it has no structural defects.
Abstract:
An elastic deformable cushion comprises: an elastoplastic curved piece made of elastoplastic material, and at least two elastoplastic ribs. At least two grooves are formed in an outer surface of the elastoplastic curved piece, and the grooves are separated from and not in communication with and one another. In an inner surface of the elastoplastic curved piece is formed a groove opening in an opposite direction to and located between the at least two grooves in the outer surface of the elastoplastic curved piece. The at least two elastoplastic ribs are formed in the at least two grooves in the outer surface of the elastoplastic curved piece, the elastoplastic ribs are integral with the elastoplastic curved piece, and each of the two elastoplastic ribs have a curved portion.
Abstract:
A spike structure made of different materials includes: a sole protruding portion, an interface member and a cleat member. The interface member is disposed between the sole protruding portion and the cleat member, so that the sole protruding portion does not directly contact the cleat member, but the sole protruding portion and the cleat member are in contact with the interface member, and because the interface member is easily bonded to the cleat member, the interface member and the cleat member can be fixedly combined by bonding. Besides, the interface member and the sole protruding portion are made of hard materials with similar hardness and are not easily deformed when they are in contact with each other. Therefore, the interface member and the sole protruding portion are not easily slipped off.
Abstract:
A method for forming a plastic support shell of a sole includes the steps of placing a sheet material into a first mold assembly; softening the sheet material; vacuum plastic molding; putting the plastic semi product into a cutting mold assembly; cutting the waste edge; putting into a trimming mold assembly; and trimming with a mechanical arm. The carrying mold and the pressing mold press against the inner and outer surfaces of the plastic semi product, and the restricting edge and the support edge are used to define a cutting line. Therefore, the plastic semi product can be firmly positioned and held tight, and then the mechanical arm can trim the plastic semi product under the guiding of the restricting edge and the support edge, which makes the trimming process easy and precise.
Abstract:
A method of manufacturing a sole with shoe nails made of different materials is provided. The method includes pre-forming shoe nails, putting the shoe nails in an injection molding mold, applying a surface treatment agent and an adhesive glue, injecting the heated molten sole material into a mold, binding the sole material and the shoe nails with the adhesive glue, and performing a cooling process to cause the sole material to solidify and turn into a sole and cause the adhesive glue to solidify and couple the sole and shoe nails together. The method enables a sole with shoe nails to be quickly manufactured so easily that it increases production efficiency and economic benefits.
Abstract:
A mold assembly with a plurality of replaceable insert assemblies includes a mold base with a first mold plate and a second mold plate. Each of the plurality of insert assemblies includes a female insert and a male insert, at least two of the insert assemblies have their female inserts removably disposed at an inner side of the second mold plate of the mold base, and have their male inserts removably disposed at an inner side of the first mold plate. On the mold base are provided at least two insert assemblies which can be replaced easily to meet different manufacturing needs. Besides, the mold base is provided with at least two insert assemblies, which reduces the number of times that the insert assemblies have to be replaced, so as to save labor while improving manufacturing efficiency.
Abstract:
A 3-plate mold assembly with a common mold base comprises: a stationary mold mounted on a fixed side of an injection molding machine and a movable mold mounted on a movable side of the injection molding machine. The stationary mold comprises a stationary-side fixed plate on which are disposed four pillars to be inserted through a stripper and into a female insert assembly. When new products need to be produced, it only needs to replace the female and male insert and the rest parts of the stationary and movable molds don't need to be replaced, thus substantially saving production cost.
Abstract:
A middle sole with cushioning effect is provided with a cushioning portion which is integrally formed on the middle sole, and the cushioning portion includes an airtight air chamber and is located corresponding to the heel, the arch or the front part of the wearer's feet. The middle sole is capable of reducing the time required for assembling a shoe and improving bonding strength between the middle sole and the cushioning portion thereof
Abstract:
The present invention relates to a heel cushion structure for a sneaker capable of adjusting the characteristic of the sneaker flexibly. The main body of the heel cushion structure is provided with plural separable elastic elements, so that the wearer is able to selectively screw different functional separable elastic elements according to personal needs. Thus, the wearer can selectively use the elastic elements according to personal needs. The cushion effect of the heel cushion structure of the sneaker can be adjusted by changing the separable elastic elements. Thereby, the present invention is truly a heel cushion structure that can flexibly adjust the characteristics of the sneaker.
