Abstract:
A plastic formed inflation mouth structure comprises a plastic formed body which is integrally formed with an inflation mouth by plastic injection molding. The inflation mouth includes an inflation apparatus passage and a restoration unit that are integrally formed. The inflation apparatus passage unit is formed with a notch for passage of an inflation apparatus to perform the inflation or deflation. The restoration unit applies an elastic restoration force onto the notch to make the notch assuredly enclose the inflation apparatus during the inflation and ensure a high airtightness when inflation is stopped.
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:
A shock-absorbing structure includes an elastic helical body, and an elastic helical curved tube. The elastic helical body is formed with a plurality of loops and a plurality of buffer spaces each defined between any two adjacent loops. The elastic helical curved tube is formed with a plurality of curved convex portions each inserted into a respective buffer space and urged between any two adjacent loops. Thus, the buffer spaces of the elastic helical body provide a cushioning effect. In addition, the elastic helical body and the elastic helical curved tube produce an elastic restoring force, so as to damp and reduce the stress applied on the shoe sole, thereby providing a shock-absorbing effect.
Abstract:
A spike structure of golf shoes with deformation effect has a spike disk made of thermoplastic polyurethane (TPU), and having a disk ring portion, and a pressed portion connected to an inner rim of the disk ring portion, the pressed portion is capable of actuating between a normal position and a pressed position; and a plurality of spike claws made of thermoplastic polyurethane (TPU), and radially arranged on the disk ring portion and extending outwardly and downwardly; when the pressed portion of the spike disk is in the pressed position, each of the spike claws is driven by compressed deformation of the pressed portion to deform synchronously, and each of the spike claws retracts and deforms inwardly synchronously; when the pressed portion of the spike disk is in the normal position, each of the spike claws restores to its original shape.
Abstract:
A test system with detection feedback works with a robot to which a test object is attached. The test system includes a server and a force sensor disposed to the robot. The server controls the robot to drive the test object to contact a test platform while the force sensor detects at least one reaction force on the test object to generate a sensing feedback signal for the server. When the reaction force corresponding to a direction and indicated by the sensing feedback signal does not match a force setting value, the server adjusts a level to which the robot drives the test object to move relative to the test platform so that the reaction force corresponding to the direction can match the force setting value. Therefore, the resistance acting on the test object moving relative to the test platform may be automatically maintained at the preset degree.
Abstract:
A chair with a chair back having a frame and a backrest. The backrest is connected to a bottom frame portion of the frame and two side frame portions at two opposite ends of the bottom frame portion by injection molding for a user to lean against. A hardness of the backrest is lower than a hardness of the frame, and the frame is provided with two supporting portions for correspondingly supporting two sides of the user's waist. Thereby, the components with different hardness are capable of forming the integrally formed chair back, and enabling the chair back to be both supportive and comfortable for leaning against.
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 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 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 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.
