[0036] Example

[0037] Reference Figure 2-4 As shown, this utility model discloses a molding die for a temple 70 of eyeglasses, including a panel 10, a runner plate 20, an upper moving mold 30, a lower fixed mold 40, an ejector plate 50, and a base plate 60 from top to bottom. The panel 10 has two injection ports. The upper moving mold 30 has an upper mold core 301 embedded at the bottom. The upper mold core 301 has two sets of upper molding grooves 3011. One set of upper molding grooves 3011 is used to mold the support rod part of the temple of the eyeglasses, and the other set of upper molding grooves 3011 is used to mold the soft rubber part of the temple of the eyeglasses 70.

[0038] Reference Figure 4-9 As shown, the lower fixed mold 40 is equipped with a base 41, and a rotating rod 411 is provided at the bottom of the base 41. The rotating rod 411 passes downward through the base plate 60. The lower fixed mold 40 is provided with lower mold cores 401 on both sides of the base 41. The lower mold cores 401 have two sets of first lower forming grooves 4011. The base 41 has two sets of second lower forming grooves 4131. A movable forming shaft 4152 is provided on one side of the second lower forming grooves 4131 on the base 41. Specifically, the base 41 includes a long strip block 412. The long strip block 412 has two grooves. A flow divider plate 414 is provided in the groove. The flow divider plate 414 has a glue inlet groove 4141. Inserts 413 are provided on both sides of the long strip block 412 along the length direction. The inserts 413 have second lower forming grooves 4131. The glue inlet groove 4141 is connected to the second lower forming groove 4131. The second lower forming groove 4131 is connected to the first lower forming groove 4011. During injection molding, a set of upper molding grooves 3011 covers the manifold 414 on one side of the long strip 412. Hot melt adhesive is injected from a sprue and passes through the injection groove 4141 on the manifold 414 to the second lower molding groove 4131 of the insert 413 and the first lower molding groove 4011 of the lower mold core 401, for molding the support rod part of the eyeglass temple 70. Then, the upper moving mold 30 and the lower fixed mold 40 are opened, and the rotating rod 411 pushes the long strip 412 and the insert 413 upward, so that the base 41 disengages from the lower mold core 401. After rotating the rotating rod 411 by 0°, it falls down and cooperates with another lower mold core 401 to inject and encapsulate the soft rubber part of the eyeglass temple 70. Compared with the traditional two-color injection encapsulation mold, this mold does not require removing the product. Several eyeglass temple 70 supports are detached from one side of the lower mold core 401 and rotated to the other side of the lower mold core 401 through the base 41. They cooperate with the other side of the lower mold core 401 for injection of the soft rubber part. The upper mold core 301 has a glue injection pin hole. Glue is injected through the glue injection pin hole to encapsulate the support rod of the eyeglass temple 70 with soft rubber.

[0039] Reference Figure 4-9 As shown, a strip plate 415 is movably set at the bottom of the groove below the flow divider plate 414. A vertical block 4151 is set on the strip plate 415, and a forming shaft 4152 is set on the upper side of the vertical block 4151. When the mold is closed for injection molding, the strip plate 415 drives the vertical block 4151 to drive the forming shaft 4152 to be inserted horizontally into the second lower forming groove 4131 of the insert 413 for forming the pivot hole 701 of the eyeglass temple 70. Specifically, the strip plate 415 has guide holes 4153 at both ends, and a wedge block 302 is provided at the bottom of the upper moving mold. When the upper moving mold 30 and the lower fixed mold 40 are closed, the wedge block 302 is inserted into the guide hole 4153 to drive the strip plate 415 to move, thereby driving the forming shaft 4152 to be inserted into the second lower forming groove 4131 for forming the shaft hole of the eyeglass temple 70. When the upper moving mold 30 and the lower fixed mold 40 are separated, the wedge block 302 drives the strip plate 415 to move, driving the forming shaft 4152 to be pulled out from the second lower forming groove 4131.

[0040] Reference Figure 4 As shown, two first hydraulic cylinders 601 are installed on the base plate 60, and the piston rods of the two first hydraulic cylinders 601 are respectively aligned with the two ends of the long strip block 412. Specifically, when the mold is opened, the upper moving mold 30 and the lower fixed mold 40 separate, the forming shaft 4152 exits the product from the second forming groove, and the two first hydraulic cylinders 601 push the long strip block 412 upward, so that the long strip block 412, the insert 413 and the lower mold core 401 separate, and the product stays on the long strip block 412 and the insert 413, realizing the first demolding of the product.

[0041] Reference Figure 7 and Figure 10 As shown, the ejector plate 50 includes a first ejector plate 501 and a second ejector plate 502. The first ejector plate 501 is disposed below the elongated block 412. The first ejector plate 501 is provided with a first ejector rod, which slides upward through the elongated block 412 and the diverter plate 414. The second ejector plate 502 is disposed below the first ejector plate 501. The second ejector plate 502 is provided with a second ejector rod, the upper end of which abuts against the first ejector plate 501. Specifically, a second hydraulic cylinder 402 is provided on the side of the lower mold 40. The piston rod of the second hydraulic cylinder 402 is connected to the second ejector plate 502. When the mold is opened, the second hydraulic cylinder 402 is controlled to drive the second ejector plate 502 to move upward. The second ejector plate 502 pushes the second ejector rod to push the first ejector plate 501 to move upward. The first ejector plate 501 pushes the first ejector rod to extend out from the glue inlet groove 4141 of the flow divider plate 414, pushing the residual glue in the glue inlet groove 4141 along with the product to be ejected from the second lower molding groove 4131, thus completing the demolding of the eyeglass temple 70.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
