Definitions

  • the disclosure relates to a process for making a golf ball, and more particularly to a process for making a golf ball with a built-in sensor.
  • a chip module such as a sensing module or a communication module is widely used in various application fields for immediate addressing and information measurement of an object.
  • the sensing module or the communication module may be installed in a golf ball to obtain information regarding the speed, the position and the like of the golf ball such that it is convenient for a golf player to track the flying trajectory of the golf ball and/or find the landing position of the golf ball.
  • a cell is usually installed along with the chip module in the golf ball so as to provide electric power for the chip module.
  • the golf ball is made by compression molding at a temperature that is usually above 150° C., the cell and the chip module are likely to be damaged due to direct contact with a high temperature molding material for making the golf ball.
  • An object of the disclosure is to provide a process for making a golf ball to overcome the aforesaid disadvantage of the prior art.
  • a process for making a golf ball with a built-in sensing assembly comprising steps of:
  • the upper segments of the left and right circular surfaces are separated by a dividing plane which extends into the central chamber such that the upper segments of the left and right circular surfaces are movable away from each other to permit placement of the sensing assembly into the central chamber while vesting the left and right hemispherical bodies with a biasing force to bias the upper segments of the left and right circular surfaces to move toward each other;
  • FIG. 1 is a flow diagram of an embodiment of a process for making a golf ball with a built-in sensing assembly according to the disclosure
  • FIGS. 2 to 5 are schematic sectional views showing consecutive steps of the embodiment.
  • FIG. 6 is a schematic sectional view of a golf ball made by the embodiment.
  • an embodiment of a process for making a golf ball with a built-in sensing assembly includes steps of a) providing a spherical hollow core 3 , b) molding an intermediate shell layer, and c) molding a cover.
  • the spherical hollow core 3 is made from a deformable resilient material and defines a central chamber 31 configured to fittingly accommodate a sensing assembly 4 .
  • the deformable resilient material may be selected from the group consisting of an epoxy resin, rubber, and a combination thereof.
  • the spherical hollow core 3 includes opposite left and right hemispherical bodies 33 , 34 respectively having left and right circular surfaces 35 , 36 contiguous with each other.
  • the left circular surface 35 has a left cavity 37 , and upper and lower segments 354 , 355 .
  • the left cavity 37 extends leftward to terminate at a left abutment surface 351 , and extends in an upward-and-downward direction to terminate at a left ceiling surface 352 and a left bottom surface 353 .
  • the left cavity 37 serves as a left chamber half.
  • the upper and lower segments 354 , 355 are diametrically symmetrical to each other, and border the left ceiling surface 352 and the left bottom surface 353 , respectively.
  • the right circular surface 36 has a right cavity 38 , and upper and lower segments 364 , 365 .
  • the right cavity 38 extends rightward to terminate at a right abutment surface 361 , and extends in the upward-and-downward direction to terminate at a right ceiling surface 362 and a right bottom surface 363 .
  • the right cavity 38 serves as a right chamber half which mates with the left chamber half to form the central chamber 31 .
  • the upper and lower segments 364 , 365 are diametrically symmetrical to each other, and border the right ceiling surface 362 and the right bottom surface 363 , respectively.
  • the upper segments 354 , 364 of the left and right circular surfaces 35 , 36 are separated by a dividing plane 32 , which extends into the central chamber 31 such that the upper segments 354 , 364 of the left and right circular surfaces 35 , 36 are movable away from each other to permit placement of the sensing assembly 4 into the central chamber 31 while vesting the left and right hemispherical bodies 33 , 34 with a biasing force to bias the upper segments 354 , 364 of the left and right circular surfaces 35 , 36 to move toward each other.
  • a gravity center of the sensing assembly 4 coincides with a center of the spherical hollow core 3 after the sensing assembly 4 is fittingly accommodated in the spherical hollow core 3 .
  • the spherical hollow core 3 fittingly accommodating the sensing assembly 4 is placed within a first mold 5 which includes a first upper mold part 51 , a first lower mold part 52 cooperating with the first upper mold part 51 to define a first mold cavity 55 , a plurality of first pins 53 removably inserted into the first mold cavity 55 through the first upper mold part 51 and the first lower mold part 52 , and a first guiding passage 54 provided in the first upper mold part 51 and fluidly communicating with the first mold cavity 55 .
  • a first molding material in a fluidic state is introduced into the first molding space through the first guiding passage 54 at an elevated temperature that is lower than a softening point of the deformable resilient material of the spherical hollow core 3 , followed by cooling to form an intermediate shell layer 6 which encloses the spherical hollow core 3 .
  • the first molding material for the intermediate shell layer 6 is selected from the group consisting of natural rubber, ionomer, and a combination thereof.
  • the intermediate shell layer 6 which encloses the spherical hollow core 3 fittingly accommodating the sensing assembly 4 is placed within a second mold 7 which includes a second upper mold part 71 , a second lower mold part 72 cooperating with the second upper mold part 71 to define a second mold cavity 75 , a plurality of second pins 73 removably inserted into the second mold cavity 75 through the second upper mold part 71 and the second lower mold part 72 , and a second guiding passage 74 provided in the second upper mold part 71 and fluidly communicating with the second mold cavity 75 .
  • a second molding material in a fluidic state is introduced into the second molding space through the second guiding passage 74 , followed by cooling to form a cover 8 which encloses the intermediate shell layer 6 so as to obtain a golf ball 1 shown in FIG. 6 .
  • the second molding material for the cover 8 is selected from the group consisting of thermoplastic polyurethane, ionomer, and a combination thereof.
  • the sensing assembly 4 Since the sensing assembly 4 is placed in the central chamber 31 of the spherical hollow core 3 which is made from a deformable resilient material having a softening point higher than the elevated temperature at which the intermediate shell layer 6 is molded, the sensing assembly 4 which includes the chip module 41 and the battery 42 will not be damaged in the course of molding the intermediate shell layer 6 .
  • the gravity center of the sensing assembly 4 coincides with the center of the spherical hollow core 3 after the sensing assembly 4 is fittingly accommodated in the spherical hollow core 3 , the golf ball 1 thus made may fly stably after being struck.
