Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a fully automatic mold opening and closing device. Background Technology

[0002] The core components of a mold, including the cavity and core or the punch and die, determine the final shape of the product. When injection molding a complex product, the internal contour of the cavity is the outer shape of the product, while the core forms the internal structure of the product. Mold closing and mold opening are considered important steps in the use of a mold. Mold closing refers to merging the upper and lower molds together, while mold opening refers to separating the upper and lower molds.

[0003] During the mold opening and closing process, if the mold is not closed properly, a gap will exist between the upper and lower molds. This will cause changes in the mold cavity size, resulting in a thinner wall thickness in that part of the product. Furthermore, the gap will allow the injection molding material to seep in, causing defects such as flash and burrs on the product surface. If the mold is not opened properly, the distance between the upper and lower molds will be too small, causing the molded product to collide with the upper mold, which can easily damage the product. Based on the above problems, this application proposes a fully automatic mold opening and closing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fully automatic mold opening and closing device to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic mold opening and closing device includes a mounting base. A lower mold and a mounting column are fixedly mounted on the top of the mounting base. A mounting plate is fixedly mounted on the top of the mounting column. A hydraulic push rod is fixedly mounted on the top of the mounting plate. An upper mold is fixedly mounted on the output end of the hydraulic push rod. An opening control component is provided between the top of the upper mold and the bottom of the mounting plate. A buffer plate and a limiting ring are slidably mounted on the surface of the mounting column. A vertical spring is connected between the bottom of the buffer plate and the top of the mounting base. The limiting ring is fixedly mounted on the upper mold. A closing control component is provided between the bottom of the buffer plate and the top of the mounting base.

[0007] Preferably, the mold opening control component includes a fixed plate fixedly installed on the top of the mounting plate.

A limit slide is fixedly installed on the surface of the push rod. A transverse spring is fixedly installed on one side of the limit slide. A push block is overlapped at the end of the push rod. The push block is fixedly installed on the top of the upper mold.

[0008] Preferably, the push rod includes a movable rod, which is slidably disposed inside the mounting sleeve. The limiting slide plate is fixedly mounted on the surface of the movable rod. A metal ball is rotatably disposed at one end of the movable rod near the push block. A limiting circular plate is overlapped on the surface of the metal ball and is fixedly mounted on one end of the movable rod near the push block.

[0009] Preferably, the limiting slide plate has a rectangular structure and is slidably disposed inside the mounting sleeve, and the limiting slide plate is made of metal.

[0010] Preferably, the mold closing control component includes a mounting shell fixedly installed on the top of the mounting base. A downward pressure sensor is fixedly installed on both the front and rear side walls of the mounting shell. A slider is slidably installed inside the mounting shell. A hinge plate is installed on the top of the slider through a hinge seat. A connecting plate is overlapped on the surface of the hinge plate. The connecting plate is fixedly installed on the bottom of the buffer plate. A mounting shaft is fixedly installed inside the connecting plate.

[0011] Preferably, limit protrusions are fixedly provided on both the left and right sides of the slider, and limit grooves are provided on both the left and right sides of the mounting shell, with the limit grooves and limit protrusions being slidably connected.

[0012] Preferably, the push block has a T-shaped structure, the top of the push block has a semi-elliptical structure, and the push block is made of metal.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This fully automatic mold opening and closing device drives the upper mold to move up and down through a hydraulic push rod, so that the upper mold and the lower mold close or open. The mold closing control component controls the degree of mold closing between the upper mold and the lower mold, and the mold opening control component controls the degree of mold opening between the upper mold and the lower mold. This avoids the situation where the wall thickness of the product becomes thinner in that part due to changes in the mold cavity size, and the appearance of flash and burrs on the product surface. It also avoids the situation where the molded product collides with the upper mold and is damaged due to incomplete mold opening. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-4An automatic mold opening and closing device includes a mounting base 1. A lower mold 25 and a mounting column 2 are fixedly mounted on the top of the mounting base 1. A mounting plate 3 is fixedly mounted on the top of the mounting column 2. A hydraulic push rod 4 is fixedly mounted on the top of the mounting plate 3. An upper mold 5 is fixedly mounted on the output end of the hydraulic push rod 4. An opening control component is provided between the top of the upper mold 5 and the bottom of the mounting plate 3. A buffer plate 16 and a limiting ring 18 are slidably mounted on the surface of the mounting column 2. A vertical spring 17 is connected between the bottom of the buffer plate 16 and the top of the mounting base 1. The limiting ring 18 is fixedly mounted on the upper mold 5. A closing control component is provided between the bottom of the buffer plate 16 and the top of the mounting base 1. The opening control component includes a fixed... A fixed plate 6 is fixedly installed on the top of the mounting plate 3. L-shaped plates 7 and upper pressure sensors 8 are fixedly installed on opposite sides of the fixed plate 6. A mounting sleeve 9 is fixedly installed on the side of the L-shaped plate 7 away from the fixed plate 6. A push rod is slidably installed inside the mounting sleeve 9. A limit slide plate 11 is fixedly installed on the surface of the push rod. The limit slide plate 11 has a rectangular structure and slides inside the mounting sleeve 9. The limit slide plate 11 is made of metal. A transverse spring 12 is fixedly installed on one side of the limit slide plate 11. A push block 15 is overlapped at the end of the push rod. The push block 15 has a T-shaped structure and a semi-elliptical top. The push block 15 is also made of metal. The push block 15 is not easily deformed, and its semi-elliptical top facilitates the movement of the push rod, thereby allowing the push rod to apply pressure to the upper pressure sensor 8. The push block 15 is fixedly installed on the top of the upper mold 5. The push block 15 pushes the push rod, causing the limiting slide plate 11 to compress the transverse spring 12, which in turn pushes the upper pressure sensor 8 to apply pressure. When the upper pressure sensor 8 detects a pressure change, the pressure no longer changes, indicating that the upper mold 5 and the lower mold 25 have completed the mold opening. The mold closing control assembly includes a mounting shell 19 fixedly installed on the top of the mounting base 1. Lower pressure sensors 20 are fixedly installed on the front and rear side walls of the mounting shell 19. The interior of the mounting shell 19... A slider 21 is provided, and a hinge plate 22 is mounted on the top of the slider 21 via a hinge seat. A connecting plate 23 is attached to the surface of the hinge plate 22 and is fixedly installed at the bottom of the buffer plate 16. An installation shaft 24 is fixedly installed inside the connecting plate 23 and is rotatably connected to the hinge plate 22. During the mold closing process, the upper mold 5 pushes the buffer plate 16 downward through the limit ring 18, and the connecting plate 23 pushes the hinge plate 22 to flip through the installation shaft 24, so that the hinge plate 22 pushes the slider 21 through the hinge seat to apply pressure to the lower pressure sensor 20. When the lower pressure sensor 20 detects that the applied pressure has reached the preset value, it indicates that the upper mold 5 and the lower mold 25 have completed the mold closing.

[0021] Specifically, the push rod includes a movable rod 10, which is slidably disposed inside the mounting sleeve 9. A limiting slide plate 11 is fixedly mounted on the surface of the movable rod 10. A metal ball bearing 13 is rotatably disposed at the end of the movable rod 10 near the push block 15. A limiting circular plate 14 is overlapped on the surface of the metal ball bearing 13 and is fixedly mounted on the end of the movable rod 10 near the push block 15. When the push block 15 pushes the push rod to move, it first contacts the metal ball bearing 13, pushing the metal ball bearing 13 to roll on its surface, so that the metal ball bearing 13 pushes the movable rod 10 to move, so that the movable rod 10 applies pressure to the upper pressure sensor 8, reducing the friction between the push rod and the push block 15, and avoiding excessive friction between the push rod and the push block 15, which would cause the push rod to wear and prevent the push rod from applying pressure to the upper pressure sensor 8.

[0022] Specifically, limit protrusions are fixedly provided on both the left and right sides of the slider 21, and limit grooves are provided on both the left and right sides of the mounting shell 19. The limit grooves are slidably connected to the limit protrusions. The limit protrusions and limit grooves facilitate the position limitation of the slider 21, so that the slider 21 will not fall out of the mounting shell 19, and can ensure that the slider 21 moves horizontally, so that the slider 21 can apply pressure to the pressure sensor 20.

[0023] This fully automatic mold opening and closing device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0024] In use: When the lower mold 25 and the upper mold 5 are closed, the drive output end of the upper mold 5 pushes the upper mold 5 downward, causing the upper mold 5 to close with the lower mold 25. At the same time, the upper mold 5 drives the limiting ring 18 downward, causing the limiting ring 18 to push the buffer plate 16 to compress the vertical spring 17. The buffer plate 16 drives the mounting shaft 24 downward through the connecting plate 23, causing the mounting shaft 24 to drive the top of the hinge plate 22 downward, causing the bottom end of the hinge plate 22 to push the slider 21 to move through the hinge seat, causing the sliders 21 to move away from each other. When the slider 21 contacts the detection end of the lower pressure sensor 20 and applies pressure to the detection end of the lower pressure sensor 20, When the lower pressure sensor 20 detects a pressure change and reaches a preset value, it indicates that the lower mold 25 and the upper mold 5 have completed mold closing. When the lower mold 25 and the upper mold 5 open, the hydraulic push rod 4 drives the output end to move the upper mold 5 upward, causing the upper mold 5 to move the push block 15 upward. The push block 15 is inserted between the push rods, causing the push rod to drive the limit slide plate 11 to compress the transverse spring 12, so that the push rod contacts the detection end of the upper pressure sensor 8 and applies pressure to the detection end of the upper pressure sensor 8. When the upper pressure sensor 8 detects a pressure change, it indicates that the lower mold 25 and the upper mold 5 have completed mold opening, thus enabling the mold opening and closing to be fully automatic.
