Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold delayed ejection structure. Background Technology

[0002] Molds are an indispensable and crucial piece of equipment in injection molding. Injection molding is a method of forming a product by injecting raw material at a certain temperature into the gap between a punch and a die. Because injection molding offers advantages such as low molding costs, short molding cycles, and a simple molding process, it is widely used in the product manufacturing industry.

[0003] However, existing molds on the market require ejection devices to eject the injection-molded mold. However, the existing ejection structures are all single fixed structures. When in use, due to the lack of a buffer delay structure, the product does not have enough time to cool and solidify, which can easily cause deformation when ejecting the product.

[0004] Therefore, it is necessary to provide a mold delayed ejection structure to solve the above-mentioned technical problems. Utility Model Content

The vertical rods of the two L-shaped guide rods pass through the corresponding square sleeves. Symmetrical push plates are fixedly connected to both ends of the two square sleeves. Each of the two square sleeves has a corresponding guide hole on one side. Two ejector screws pass through the corresponding guide holes and are threaded to one of the corresponding threaded holes.

[0031] A mold delayed ejection structure includes a punch assembly 1, an ejection module 2, and a controller 3;

[0032] The punch assembly 1 includes a support rod 11, a worktable 12, an upper die holder 13, a lower die holder 14, a mold cavity 15, a punch 16, and an ejector rod 17.

[0033] The ejector module 2 includes two square sleeves 212, which are fixedly connected to the two sides of the workbench 12. Each of the two square sleeves 212 has a corresponding L-shaped guide rod 21. The upper part of the vertical rod of each of the two L-shaped guide rods 21 is provided with a set of threaded holes 22. The vertical rods of each of the two L-shaped guide rods 21 pass through the corresponding square tubes 28. The two ends of each of the two square tubes 28 are fixedly connected to symmetrical push plates 27. Each side of each of the two square tubes 28 is provided with a corresponding guide hole 29. Two ejector screws 23 pass through the corresponding guide holes 29 and are threadedly connected to one of the corresponding threaded holes 22.

[0034] The crossbars of the two L-shaped guide rods 21 are respectively fixedly connected to the disks 24. A set of round rods 25 are respectively fixedly connected to the upper side of the disks 24. The set of round rods 25 passes through the corresponding round holes 211. The upper ends of the set of round rods 25 are respectively fixedly connected to the corresponding arc-shaped top plates 26. The set of arc-shaped top plates 26 are respectively set in the corresponding arc-shaped grooves 210. The set of arc-shaped grooves 210 are respectively set at the mold cavity 15. The set of round holes 211 are respectively set at the lower mold base 14. The set of round holes 211 are respectively connected to the set of arc-shaped grooves 210.

[0035] The punch press assembly 1 includes the worktable 12, the worktable 12 is fixedly connected to the corresponding support rods 11, a group of support rods 11 pass through and slide to the upper die holder 13, and the lower ends of a group of support rods 11 are fixedly connected to the lower die holder 14.

[0036] The model cavity 15 is fixedly provided on the upper middle part of the lower mold base 14.

[0037] The punch 16 is fixedly installed on the lower side of the upper mold base 13.

[0038] A pair of symmetrical push rods 17 are fixedly connected to both sides of the upper mold base 13.

[0039] The controller 3 is fixedly connected to one side of the lower mold base 14.

[0040] The controller 3 is electrically connected to the punch press assembly 1.

[0041] After the arc-shaped top plate 26 enters the arc-shaped groove 210, the model cavity 15 forms a complete model cavity 15.

[0042] Working principle: First, loosen the set screw 23. Move the square tube 28 according to the required setting time of the mold 4, so that the square tube 28 moves to the appropriate position along the L-shaped guide rod 21. The higher the position of the square tube 28, the longer the delay. At this time, tighten the set screw 23, so that the set screw 23 passes through the guide hole 29 and is threaded into the corresponding threaded hole 22, thus fixing the square tube 28. Next, place the material to be injected into the mold cavity 15. The controller 3 controls the punch assembly 1 to start working. The upper mold base 13 drives the punch 16 to move downwards, so that the punch 16 completes the stamping operation on the injection material in the mold cavity 15. The controller 3 controls the upper mold base 13 to drive the ejector rod 17 to move upward along the support rod 11. During the movement, the mold 4 completes cooling and shaping, causing the ejector rod 17 to touch the push plate 27 and push the push plate 27 to move upward. The top plate 27 drives the L-shaped guide rod 21 to move upward along the square sleeve 212 through the square tube 28. At this time, the two L-shaped guide rods 21 drive a set of round rods 25 to move upward along the round hole 211 through the disc 24. The set of round rods 25 drives the arc-shaped top plate 26 to move upward. The set of arc-shaped top plates 26 pushes the mold 4 in the mold cavity 15 to move upward, realizing the delayed ejection of the mold 4.

[0043] Beneficial effects: The square tube 28 is moved according to the required setting time of the mold 4, so that the square tube 28 is moved to a suitable position. The higher the position of the square tube 28, the longer the delay. The material to be injected is placed in the mold cavity 15. The controller 3 controls the punch assembly 1 to work, so that the punch 16 completes the stamping operation on the injection material in the mold cavity 15. Through the ejection module 2, the upper mold seat 13 drives the ejector rod 17 to move upward along the support rod 11. During the movement, the mold 4 completes cooling and setting, so that the ejector rod 17 touches the push plate 27 and pushes the push plate 27 to move upward. Finally, a set of round rods 25 drives the arc-shaped top plate 26 to move upward, so that a set of arc-shaped top plates 26 pushes the mold 4 in the mold cavity 15 to move upward, realizing the delayed ejection of the mold 4.
