A support table is fixedly installed at the top end of the base. A lower die is fixedly installed at the left side of the top end of the support table. Four guide columns are fixedly connected to the top end of the support table. The four guide columns are distributed around the lower die. The top ends of the four guide columns are fixedly connected to a top plate. A driving cylinder is fixedly installed at the top end of the top plate. The output end of the driving cylinder is fixedly connected to an upper die support plate. The upper die support plate is slidably sleeved on the four guide columns. A lower end of the upper die support plate is fixedly connected to an upper die. The ejection mechanism includes a lifting cylinder. The lifting cylinder is fixedly installed at the top end of the base. The output end of the lifting cylinder is fixedly connected to a connecting plate. A ejector rod and a T-shaped slide bar are symmetrically fixedly connected to the connecting plate left and right. The ejector rod slidably passes through the support table and the lower die. A blanking plate is slidably arranged at the bottom end inside the lower die. The bottom end of the blanking plate is fixedly connected to the top end of the ejector rod. The blanking mechanism includes a T-shaped slide bar. The T-shaped slide bar is slidably arranged at the right side of the top end of the support table. The bottom end of the T-shaped slide bar is fixedly connected to the right side of the top end of the connecting plate. The top end of the T-shaped slide bar is hinged to a transmission strip plate. A vertical plate is fixedly connected to the top end of the support table. A guiding hole is provided on the vertical plate. A T-shaped guiding rod is slidably arranged on the vertical plate through the cooperation of the guiding hole. The right end of the T-shaped guiding rod is hinged to the top end of the transmission strip plate. A pushing plate is fixedly connected to the left end of the T-shaped guiding rod. Two groups of T-shaped guide columns are symmetrically slidably arranged on the pushing plate. The bottom ends of the two groups of T-shaped guide columns are fixedly connected to a connecting frame. Springs are sleeved on each of the two groups of T-shaped guide columns. Two ends of each spring are respectively connected to the bottom end of the pushing plate and the top end of the connecting frame. A roller is rotatably installed on the connecting frame.

[0007] Preferably, two guide rods are fixedly connected between the top end of the base and the bottom end of the support table. The two guide rods are symmetrically distributed on both sides of the lifting cylinder. The connecting plate is slidably sleeved on the two guide rods.

[0008] Preferably, a sliding sleeve is fixedly arranged in the guiding hole on the vertical plate.

[0009] Preferably, anti-slip rubber pads are fixedly connected to the four corners of the bottom end of the base.

[0010] Preferably, a reinforcing plate is fixedly connected between the right end of the vertical plate and the top end of the support table.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: When in use, the pre-expanded particles are placed in the lower mold. By starting the driving cylinder, the driving cylinder pushes the upper mold support plate and the upper mold downward, so that the upper mold cover presses on the lower mold. Through the extrusion of the upper mold and the lower mold, the pre-expanded particles in the mold are heated and softened and expanded, and are fused together. After cooling, a foam product is formed. When taking out the workpiece, after the upper mold is lifted, by starting the lifting cylinder, the lifting cylinder pushes the connecting plate upward, and the connecting plate pushes the ejector rod and the T-shaped slide rod to slide upward together. When the ejector rod slides upward, it pushes the ejector plate to eject the cooled and formed foam product out of the lower mold. At the same time, when the T-shaped slide rod slides upward, it pushes the T-shaped guide rod to slide leftward through the transmission strip plate, so that the T-shaped guide rod pushes the push plate and the roller to move leftward. When the ejector plate ejects the foam product until the bottom end of the foam product is horizontal with the top end of the lower mold, the T-shaped guide rod just pushes the push plate and the roller to the right side of the top end of the ejector plate. The bottom of the roller abuts against the right side of the top end of the ejector plate, and the left end of the push plate contacts the right end of the foam product. Then the lifting cylinder continues to push the ejector rod and the T-shaped slide rod upward through the connecting plate, so that the ejector plate continues to push the foam product upward, and the T-shaped guide rod continues to push the push plate and the roller to move leftward. At this time, the push plate starts to push the foam product to move leftward on the ejector plate, and the roller rolls leftward on the ejector plate. And during the process of the roller rolling leftward, the roller is pushed upward by the ejector plate, so that the connecting frame pushes the T-shaped guide post to slide upward, and the spring is compressed until the push plate pushes the foam product off the ejector plate. At this time, the roller just rolls to the left end of the ejector plate, thus easily completing the ejection and blanking of the formed foam product, effectively avoiding manual extraction, effectively reducing the labor intensity, making the taking of the foam product more convenient, and improving the convenience of using the mold.

[0024] For a foam molding die of the present utility model, its working principle is as follows: during use, pre-expanded particles are placed in the lower die 3. By starting the driving cylinder 6, the driving cylinder 6 pushes the upper die support plate 7 and the upper die 8 downward, so that the upper die 8 covers and presses on the lower die 3. Through the extrusion of the upper die 8 and the lower die 3, the pre-expanded particles in the die are heated and softened and expanded, and are fused together. After cooling, a foam product is formed. When taking out the part, after the upper die 8 is lifted, by starting the lifting cylinder 9, the lifting cylinder 9 pushes the connecting plate 10 upward. The connecting plate 10 pushes the ejector rod 11 and the T-shaped slide rod 13 to slide upward together.

When the ejector plate 12 ejects the foam product until the bottom end of the foam product is horizontal with the top end of the lower die 3, the T-shaped guide rod 16 just pushes the push plate 17 and the roller 21 to the right side of the top end of the ejector plate 12. The bottom of the roller 21 abuts against the right side of the top end of the ejector plate 12, and the left end of the push plate 17 contacts the right end of the foam product. Then the lifting cylinder 9 continues to push the ejector rod 11 and the T-shaped slide rod 13 upward through the connecting plate 10, so that the ejector plate 12 continues to push the foam product upward. The T-shaped guide rod 16 continues to push the push plate 17 and the roller 21 to move leftward. At this time, the push plate 17 starts to push the foam product to move leftward on the ejector plate 12, and the roller 21 rolls leftward on the ejector plate 12. And during the leftward rolling process of the roller 21, the roller 21 is pushed upward by the ejector plate 12, so that the connecting frame 19 pushes the T-shaped guide post 18 to slide upward, and the spring 20 is compressed until the push plate 17 pushes the foam product off the ejector plate 12. At this time, the roller 21 just rolls to the left end of the ejector plate 12, thus easily completing the ejection and blanking of the formed foam product.
