Description

Technical Field

[0001] This utility model relates to the technical field of mold closing drive devices, specifically a support base for a flip-type mold closing drive device. Background Technology

[0002] In mechanical manufacturing, especially mold manufacturing and processing, a mold clamping machine is a specialized mold processing equipment. It is mainly used in the later stages of mold making to fit the left and right molds together and apply the required pressure to close the mold. It adopts a variety of reliable devices, including a fixed mold base and a movable mold base, and is equipped with a flipping device, hydraulic push rods, etc. to flip the left and right mold bases. The left and right mold bases are then pulled and clamped by hydraulic cylinders on both sides to close the mold.

[0003] In existing tilting mold closing drive devices, the support base allows two mold holders to move relative to each other on the base and clamp together. However, during relative movement, there is significant friction and wear between the bottom of the mold holders and the base, which increases the resistance during mold closing. Over time, wear on the mold holders reduces the accuracy of mold closing and can easily lead to positional deviations. Furthermore, after the mold holders are tilted to the closing position, the push-pull structure on their rear side is relatively simple, making it prone to skewing during pushing and pulling. The uneven pushing and pulling force on the mold holders affects the tightness of the clamping and closing between the two mold holders.

[0004] Therefore, a support base for a flip-type mold closing drive device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a support base for a flip-type mold closing drive device. This solves the problem that after the mold base is flipped to the mold closing position, the push-pull structure on its rear side is relatively simple, which easily leads to skewing when pushing and pulling the mold base, and the uneven pushing and pulling force on the mold base affects the tightness of the clamping and closing between the two mold bases.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support base for a flip-type mold closing drive device, comprising a base, a fixed frame fixedly installed at one end of the top of the base, a first mold base rotatably installed at the inner end of the fixed frame, a movable frame movably installed at the other end of the top of the base, a second mold base rotatably installed at the inner end of the movable frame, a first hydraulic cylinder installed between the two sides of the second mold base and the first mold base, a push-pull flipping mechanism installed at the rear of both the second mold base and the first mold base, and a guide moving mechanism provided between the bottom end of the movable frame and the top end of the base;

[0007] The push-pull flipping mechanism includes a second hydraulic cylinder. The bottom end of the second hydraulic cylinder is hinged to the inner bottom end of the movable frame, and its top end is hinged to the rear side of the second mold base. A support plate is fixed to the surface of the telescopic rod of the second hydraulic cylinder. Tightening bolts are rotatably passed through the four corners of the surface of the support plate. An abutment plate is fixed to the inner end of the tightening bolt, and the abutment plate abuts against the rear side of the second mold base.

[0008] Preferably, side plates are fixed on both sides of the fixed frame and the movable frame, and the first hydraulic cylinder is horizontally fixed between the two side plates with a gap between the fixed frame and the movable frame.

[0009] Preferably, a first hinge seat is fixed to the bottom of the movable frame, the bottom of the second hydraulic cylinder is hinged to the middle of the first hinge seat, and a second hinge seat is fixed to the middle of the rear side of the second mold base.

[0010] Preferably, a rotating column is fixed to the top of the telescopic rod of the second hydraulic cylinder, and the rotating column is hingedly installed inside the second hinge seat, and the second hydraulic cylinder is tilted.

[0011] Preferably, the support plate is a rectangular plate structure and is inclinedly set on the rear side of the second mold base. It has connection holes at its four corners. The connection holes are threaded holes, through which the tightening bolts rotate.

[0012] Preferably, the guiding and moving mechanism includes a movable roller, and mounting plates are fixed on both sides of the bottom end of the movable frame. The movable roller rotates between the two mounting plates, and its bottom end protrudes downward from the bottom end of the mounting plate. A guide groove is opened at the top of the base. The guide groove is a long strip structure and is set horizontally. Its cross-section is a T-shaped structure.

[0013] Preferably, the bottom end of the movable roller slides and overlaps the bottom end of the guide groove, and the bottom ends of both sides of the mounting plate are fixed with snap-fit ​​plates. The snap-fit ​​plates are horizontally set and slide and snap into the inside of both sides of the guide groove, and the snap-fit ​​plates and the guide groove are slidably snap-fit ​​connected.

[0014] Preferably, the bottom of the side plate has a groove, and the bottom of the base has slide rails fixed on both sides. The slide rails slide through the grooves and are long and horizontal.

[0015] Preferably, a support column is fixed to the top edge of the base, and a top plate is fixed to the top of the support column. The top plate is installed on the top of the fixed frame and the movable frame. Infrared components are installed at the four corners of the top of the top plate. Both the base and the top plate are rectangular structures and are horizontally arranged.

[0016] Compared with the prior art, the present invention provides a support base for a flip-type mold closing drive device, which has the following advantages:

[0017] 1. Install a movable frame on the base, and install a second mold base that can be flipped on the inner end of the movable frame via a second hydraulic cylinder. Also, install the first mold base that can be flipped on the inner end of the fixed frame via a second hydraulic cylinder. In this way, the first hydraulic cylinders on both sides of the first mold base and the second mold base move simultaneously to pull both sides of the movable frame at the same time, thereby making the second mold base move stably on the base and close to the first mold base for clamping and mold closing.

[0018] 2. Furthermore, the side plate is slidably engaged with the top of the slide rail via a sliding groove, and the top of the movable frame is rotatably mounted with a moving roller via a mounting plate. The moving roller is slidably mounted inside the guide groove. In this way, the movable frame is mounted on the base with a gap. The movable frame and the second mold base can be moved by the slide rail and the moving roller, which can reduce the friction and wear between the movable frame and the base and reduce the resistance when the second mold base moves.

[0019] 3. Furthermore, during the movement of the movable frame on the base, the snap-fit ​​plates at the bottom of both sides of the mounting plate slide and snap into both sides of the guide groove, thereby making the mounting plate and the base slide and snap-fit ​​together, improving the stability of the movable frame moving on the base.

[0020] 4. Before the second mold base and the first mold base are closed, the first mold base and the second mold base are adjusted to face each other by the second hydraulic cylinder. During this process, when the second hydraulic cylinder pushes and pulls the first mold base and the second mold base to turn, the tightening bolt passes through the support plate and drives the abutment plate to abut against the four corners of the rear side of the first mold base and the second mold base. This can enhance the stability of the first mold base and the second mold base when turning, and can also tighten and stabilize the first mold base and the second mold base when closing, so as to avoid the first mold base and the second mold base from shaking due to uneven force.

[0026] 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.

[0027] Example:

[0028] Please see Figure 1 - Figure 4 The support base of the flip-type mold closing drive device in this embodiment includes a base 1. A fixed frame 7 is fixedly installed at one end of the top of the base 1. A first mold base 6 is rotatably installed at the inner end of the fixed frame 7. A movable frame 11 is movably installed at the other end of the top of the base 1. A second mold base 10 is rotatably installed at the inner end of the movable frame 11. A first hydraulic cylinder 5 is installed between the two sides of the second mold base 10 and the first mold base 6. A push-pull flipping mechanism is installed on the rear side of both the second mold base 10 and the first mold base 6. A guide moving mechanism is provided between the bottom end of the movable frame 11 and the top end of the base 1.

[0029] The push-pull flipping mechanism includes a second hydraulic cylinder 12. The bottom end of the second hydraulic cylinder 12 is hinged to the inner bottom end of the movable frame 11, and its top end is hinged to the rear side of the second mold base 10. A support plate 20 is fixed on the surface of the telescopic rod of the second hydraulic cylinder 12. Tightening bolts 19 are rotatably passed through the four corners of the surface of the support plate 20. An abutment plate 21 is fixed to the inner end of the tightening bolts 19, and the abutment plate 21 abuts against the rear side of the second mold base 10.

[0030] The bottom of the movable frame 11 is fixed with a first hinge seat 13, the bottom of the second hydraulic cylinder 12 is hinged and installed in the middle of the first hinge seat 13, and the middle of the rear side of the second mold base 10 is fixed with a second hinge seat 23.

[0031] The top of the telescopic rod of the second hydraulic cylinder 12 is fixed with a rotating column 22, which is hinged inside the second hinge seat 23. The second hydraulic cylinder 12 is set at an angle.

[0032] The support plate 20 is a rectangular plate structure and is inclinedly set on the rear side of the second mold base 10. There are connection holes 24 at its four corners. The connection holes 24 are threaded holes, and the tightening bolt 19 rotates through the connection holes 24.

[0033] Before the second mold base 10 and the first mold base 6 are closed, the first mold base 6 and the second mold base 10 are adjusted to face each other by the second hydraulic cylinder 12.

[0034] During this process, when the second hydraulic cylinder 12 pushes, pulls, and flips the first mold base 6 and the second mold base 10, the tightening bolt 19 passes through the support plate 20 and drives the abutment plate 21 to abut against the four corners of the rear side of the first mold base 6 and the second mold base 10, thereby enhancing the stability of the first mold base 6 and the second mold base 10 when flipping.

[0035] Furthermore, the mold base 6 and the mold base 10 can be tightened and stabilized to prevent the mold base 6 and the mold base 10 from shaking due to uneven force.

[0036] In detail, the guide movement mechanism includes a moving roller 14, and mounting plates 16 are fixed on both sides of the bottom end of the movable frame 11. The moving roller 14 rotates between the two mounting plates 16, and its bottom end protrudes downward from the bottom end of the mounting plate 16. A guide groove 15 is opened at the top of the base 1. The guide groove 15 is a long strip structure and is set horizontally. Its cross-section is a T-shaped structure.

[0037] The bottom end of the movable roller 14 is slidably overlapped with the bottom end of the guide groove 15. The bottom ends of both sides of the mounting plate 16 are fixed with snap-fit ​​plates 17. The snap-fit ​​plates 17 are horizontally set and are slidably snapped into the inside of the guide groove 15 on both sides. The snap-fit ​​plates 17 and the guide groove 15 are slidably snapped together.

[0038] The bottom of the side plate 2 has a groove 18, and the bottom of the base 1 has two slide rails 3 fixed on both sides. The slide rails 3 slide through the groove 18. The slide rails 3 are long strips and are set horizontally.

[0039] The side plate 2 is slidably engaged with the top of the slide rail 3 via the slide groove 18, and the bottom of the movable frame 11 is rotatably mounted with the movable roller 14 via the mounting plate 16, while the movable roller 14 is slidably mounted inside the guide groove 15.

[0040] Thus, the movable frame 11 is installed on the base 1 with a gap. The movable frame 11 and the second mold base 10 can be moved by the slide rail 3 and the moving roller 14, which can reduce the friction and wear between the movable frame 11 and the base 1 and reduce the resistance when the second mold base 10 moves.

[0041] Furthermore, during the movement of the movable frame 11 on the base 1, the snap-fit ​​plates 17 at the bottom of both sides of the mounting plate 16 slide and snap into the inside of the guide groove 15, thereby making the mounting plate 16 and the base 1 slide and snap-fit ​​connected, improving the stability of the movable frame 11 moving on the base 1.

[0042] Finally, side plates 2 are fixed on both sides of the fixed frame 7 and the movable frame 11. The first hydraulic cylinder 5 is horizontally fixed between the two side plates 2 and is spaced apart on both sides of the fixed frame 7 and the movable frame 11.

[0043] A support column 4 is fixed to the top edge of the base 1, and a top plate 8 is fixed to the top of the support column 4. The top plate 8 is installed on the top of the fixed frame 7 and the movable frame 11. Infrared components 9 are installed at the four corners of the top of the top plate 8. The infrared components 9 are infrared sensors. The brand is P+F / Pepperl+Fuchs, and the model is OBE10M-18GM60-SE4. The four infrared sensors are installed at the four corners of the top plate 8, and are arranged in pairs on both sides of the long side of the top plate 8. When a foreign object such as a head or arm passes between two infrared sensors and blocks the sensing between the two infrared sensors, the infrared sensors will detect the obstruction. Then, the control center will control the second mold base 10 to stop moving. After the obstruction leaves the space between the two infrared sensors, the control center in the mold closing drive device will control the second mold base 10 to move again. Both the base 1 and the top plate 8 are rectangular structures and are horizontally arranged.

[0044] The movable frame 11 is installed on the base 1, and the second mold base 10 is rotatably installed at the inner end of the movable frame 11 via the second hydraulic cylinder 12. The first mold base 6 is also rotatably installed at the inner end of the fixed frame 7 via the second hydraulic cylinder 12.

[0045] Thus, the first hydraulic cylinders 5 on both sides of the first mold base 6 and the second mold base 10 move simultaneously, thereby pulling both sides of the movable frame 11 at the same time, so that the second mold base 10 moves stably on the base 1 and approaches the first mold base 6 to clamp and close the mold.

[0046] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
