To provide a vent hole cleaning apparatus and a vent hole cleaning method which can accurately calculate a position of a vent hole and can automatically clean the vent hole.

[Solution] An apparatus 1 for cleaning a vent hole 5 provided on a molding surface 4 of a mold 3 for vulcanizing a rubber product. The apparatus 1 comprises a detecting means 11 for detecting a shape of the molding surface 4, a cleaning means 12 for cleaning the vent hole 5, a controlling means 13 for storing molding surface information in advance and including shape information of the molding surface 4 including a position of the vent hole 5 and for calculating the position of the vent hole 5 by comparing the shape of the molding surface 4 obtained by the detecting means 11 with the molding surface information, and a guiding means 14 for moving the cleaning means 12 based on the calculated position of the vent hole 5.

When cleaning a mold using a mold cleaning system, three-dimensional image data of a molding surface of the mold is acquired by a camera, movement of arms is controlled by a control device based on the acquired image data, and a laser head is moved along the molding surface while a laser beam provided from a laser oscillator is irradiated to remove contamination adhered to the molding surface. Cleaning is performed on a specific site, using a relatively small laser head, or also using a relatively large laser head, or cleaning is performed using a laser head having a variable laser irradiation width and setting an appropriate laser irradiation width for each site to be cleaned.

A vent hole cleaning system is disclosed. The cleaning system is comprised of a housing containing a work table and a support column. The system further comprises a robotic arm mounted on the support column. Further, a subsystem is mounted at an end, opposite to the support column, of the robotic arm. The subsystem may comprise a scanner configured to generate a contour profile of a mold. Further, a vision system may be mounted on the subsystem. The vision system may be communicably connected to the scanner. Further, the system may comprise a cleaning head communicably connected to the vision system and the scanner to enable precision positioning on the mold.

A method is provided for forming an impermeable barrier layer on an inner tire surface of a tire. An assembly is also provided along with a kit for forming an impermeable barrier layer on an inner tire surface of a tire accordingly.

A method for detaching elastomer particles that adhere on microvalves (3) disposed on the internal surface of a vehicle tire mold (2) comprises vibrating the microvalve (3) at a constant amplitude ranging between approximately 0.05 and 0.2 mm and at a frequency ranging between 20,000 and 30,000 Hz during the detachment of the particles from the microvalve (3).

The present disclosure provides a method and apparatus for cleaning a workpiece, and a method and apparatus for cleaning a ventless tire segment mold. The method for cleaning a workpiece comprises: heating the workpiece to a preset temperature; and applying a cleaning solution onto the workpiece so that the cleaning solution is vaporized instantaneously to form a micro-explosion at each shocking point, thereby peeling dirt off the workpiece and achieving the purpose of workpiece cleaning. The apparatus for cleaning a workpiece comprises: a heating device for heating the workpiece into a preset temperature range, and a cleaning device for applying a cleaning solution onto the workpiece so that the cleaning solution is vaporized instantaneously to form a micro-explosion at each shocking point, thereby peeling dirt off the workpiece and achieving the purpose of workpiece cleaning. The present disclosure not only cleans the dirt on the surface of the workpiece, but also makes a significant breakthrough in the cleaning of the gaps of micron or nano scale on the workpiece. The present disclosure has the characteristics of lower cost, simple cleaning, thorough dirt removal, etc.

A method is provided for forming an impermeable barrier layer on an inner tire surface of a tire. An assembly is also provided along with a kit for forming an impermeable barrier layer on an inner tire surface of a tire accordingly.

To prevent rubber from becoming membrane-like mold flash between mating faces and being adhered. It is a rigid core for forming a tire which comprises an annular core main body provided in an outer surface thereof with a tire molding surface for forming a raw tire. The core main body is composed of a plurality of core segments which are divided in a circumferential direction, and each of the core segments has both circumferential end surfaces as mating faces, and the mating faces adjacent to each other in the circumferential direction are butted to each other so as to form the core main body. Each of the mating faces is provided with a border recess extending along an outer peripheral edge of the mating face and formed by cutting away a corner between the tire molding surface and the mating face.

Disclosed herein is a tire molding element. The tire molding element includes at least a molding surface for molding a plurality of ground contact elements of the tire tread, comprising: a ground contact surface which contacts a road surface, and a transverse side surface and a circumferential side surface connected to said ground contact surface; and a plurality of thin plates, comprising: a main body, provided in such a way as to cut a covering layer arranged in advance on an unvulcanized green tire.

Provided is a mold cleaning system. On the basis of an identification mark assigned to a mold and detected by a mark detector when cleaning the mold, the mold cleaning system obtains shape data for the molding surface of the mold which is stored in a database, and on the basis of the obtained shape data, the mold cleaning system controls the movement of arms using the control device, moves a laser head along the molding surface thereof while irradiating with a laser beam supplied by a laser oscillator, and as a result, removes the dirt adhered to the molding surface.
