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.
Abstract:
The present invention relates to a molding device for forming a plastic article having two colors. The method for forming a plastic article having two colors uses two male dies whose positions are changed in a reciprocal manner to mate with a female die, so that two plastic materials having two different colors are in turn formed on the two male dies by a plastic injection molding process, thereby forming a plastic article having two colors.
Abstract:
An assembly structure of a chair includes: a chair frame having a front bar, a rear bar, a first side bar and a second side bar; and a chair seat detachably assembled with the chair frame and having a seat portion, a front engaging portion disposed at a front end of the seat portion to engage with the front bar, a rear engaging portion disposed at a rear end of the seat portion to engage with the rear bar, a first abutting portion disposed at one side of the seat portion to engage with and abut against the first side bar, and a second abutting portion disposed at another side of the seat portion to engage with and abut against the second side bar.
Abstract:
A test fixture for soles includes a sole member, a heel cushion, a sole connector, a ring-shaped airbag, a torque connector, and an attaching assembly. The heel cushion is disposed on a heel section of the sole member and sandwiched in between the sole member and the sole connector. The airbag is disposed on the sole connector, and the torque connector is inserted in the airbag. The torque connector includes one end connected to the sole connector, and one opposite end connected to the attaching assembly disposed on the airbag.
Abstract:
A chair has a chair back including a frame, two supporting legs and a bearing plate. The frame is integrated to the supporting legs in an injection molding manner. The bearing plate is integrated to a bottom frame portion and two side frame portions of the frame in the injection molding manner so that a user can lean against the bearing plate. The two side frame portions are located on two opposite sides of the bottom frame portion. The hardness of the bearing plate is lower than the hardness of the frame, and the hardness of the frame is lower than the hardness of the supporting leg. Therefore, two members whose materials are different in hardness are possibly constitute a chair back formed in one piece.
Abstract:
A method for manufacturing a shoe sole with multi-material spikes includes: providing a spike-forming mold which includes an upper mold and a lower mold, wherein the lower mold includes a first filling hole which is in communication with the first spike cavity, different materials are placed in the first spike cavity to form the multi-material spike; providing a first mold which includes a second spike cavity; providing a second mold which includes a second filling hole; assembling the first and second molds, together to form a sole cavity, wherein the multi-material spike is placed into the sole cavity, a sole material is filled into the sole cavity through the second filling hole, and then the multi-material spike and the sole material are adhered to each other by hot melting; and opening the first and second molds, and obtaining a shoe sole with the multi-material spike.
Abstract:
A method for integrally forming a sole with hobnails includes the following steps: providing a mold assembly, the mold assembly includes a sole forming member and a hobnail forming member, the hobnail forming member is movable with respect to the sole forming member; forming of sole and hobnails, injecting plastic material into the mold cavity to integrally form the sole and a hobnail; demolding the hobnail, moving the hobnail forming member with respect to the sole forming member to create a buffer space between the hobnail and the hobnail forming member; and demolding of the sole, taking the sole with the hobnail obtained by the previous step out of the mold assembly, wherein an arc-shaped paw portion of the hobnail is bent through the buffer space and then demolded.
Abstract:
A method for polychrome plastic material injection molding in accordance with the present invention, in which, a molding board is provided with a plurality of cores, and the cores are each provided with a plurality of cavities. The cores rotated for exchanging the positions of the cavities and together with the rotation of the molding board, whereby permitting the injection of three different colored plastic materials into the cores respectively in turn, and then forming a triple colored plastic object.
