Description

Technical Field

[0001] The utility model relates to the technical field of mobile mold frames, and more specifically, to a mobile mold frame with adjustable height during assembly. Background Art

[0002] The mold frame is the support of the mold. For example, the part that combines and fixes the various parts of the mold according to a certain rule and position on the die-casting machine and enables the mold to be installed on the die-casting machine is called the mold frame. The mold frame is a semi-finished product of the mold, composed of various steel plates and parts. It can be said to be the skeleton of the entire mold.

[0003] In order to increase the flexibility of the existing mold frame during use, rollers are usually installed under the lower mold frame to facilitate movement and save manpower. However, during the use of the mold frame, although the rollers can be locked by a locking device, the rollers are circular in design and have a small contact area with the ground, which reduces the stability of the overall mold frame. There is a problem that the mold frame may shake or loosen during work, which is low in safety and not conducive to use.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a movable mold frame with adjustable height. Utility Model Content

At the same time, through the arrangement of the telescopic cylinder, the telescopic arm in the telescopic cylinder is used to drive the up and down movement of the lifting mechanism, which is beneficial to the height adjustment of the upper mold frame and improves practicality. It should be noted that through the gradual extension of the telescopic arm, the height of the upper mold frame will also gradually increase, thereby increasing the center of gravity of the upper mold frame, which is not conducive to the overall stability of the mold frame. At this time, the distance between the support mechanisms at the end of the telescopic arm will also gradually increase due to the extension of the telescopic arm, thereby gradually increasing the overall support area of ​​the mold frame, thereby ensuring that when the upper mold frame is raised, the overall stability of the mold frame will also increase accordingly, thereby improving practicality.

[0007] Preferably, the lifting mechanism includes a support member arranged on the side surface inside the lower mold frame parallel to the extension and retraction direction of the telescopic cylinder, and the support member is vertically provided with a rotatably connected guide sleeve, the guide sleeve is located in the middle position between the support members and is connected with a gear, the gear is fixedly connected to the guide sleeve, the guide sleeve is internally threaded with a threaded rod, and the top end of the threaded rod is inserted into the bottom surface of the upper mold frame and connected thereto, and the upper mold frame can be moved up and down by the lifting mechanism, which is convenient for adjusting the height of the upper mold frame and improving practicality.

[0008] Preferably, the positions of the support members on the side walls of the lower mold frame are provided with square grooves penetrating the side walls of the lower mold frame, and the protruding end of the gear on one side close to the square groove passes through the square groove and engages with the rack, so that the movement of the rack can drive the rotation of the gear, thereby completing the height adjustment of the upper mold frame by the lifting mechanism.

[0009] Preferably, the rack can move forward and backward in the long slot, and the protruding end of the rack is flush with the outer side of the corresponding long slot, thereby ensuring that the telescopic arm can move forward and backward in the telescopic cylinder smoothly and unhindered, ensuring normal use of the equipment.

[0010] Preferably, bearings are provided on both the upper surface and the lower surface of the gear, and the bearings are located between the support members. The provided bearings ensure stable rotation of the gear and stability during height adjustment of the upper mold frame.

[0011] Preferably, the guide sleeve is slidably connected to a limit ring at a position on the upper surface of the lower mold frame, and the limit ring is fixedly connected to the upper surface of the lower mold frame. The limit ring is provided to further ensure the stable rotation of the guide sleeve and improve the stability of the upper mold frame during height adjustment.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, by setting up the supporting mechanism, during the use of the mold frame, the hydraulic cylinder is extended so that the supporting base is fully in contact with the ground, and the moving wheels are suspended, thereby ensuring the stability of the mold frame during use. When the mold frame needs to be moved, the support of the supporting base on the ground is cancelled, and the moving wheels are in contact with the ground, so that the mold frame can be flexibly moved to the required position, thereby improving the practicality of the mold frame.

[0014] 2. In the utility model, by setting up a telescopic cylinder and a lifting mechanism, when the telescopic arm in the telescopic cylinder is extending and retracting, the movement of the rack drives the rotation of the gear, so that the guide sleeve rotates relative to the threaded rod, so that the threaded rod moves up and down synchronously, thereby completing the height adjustment of the upper mold frame, improving practicality, and when the height of the center of gravity of the upper mold frame changes, the overall support area of ​​the mold frame will also increase or decrease accordingly, further improving the practicality of the mold frame.

The extension of the telescopic arm 401 in the retracting cylinder 4 drives the movement of the supporting mechanism 5 at the end of the telescopic arm 401. After moving to the appropriate position, the extension of the hydraulic cylinder 501 is controlled to move the supporting base 502 downward, so that the supporting base 502 is fully in contact with the ground, and the moving wheel 6 is suspended in the air, thereby increasing the supporting area of ​​the entire mold frame and ensuring the stability of the mold frame during use. When the mold frame needs to be moved, the support of the supporting base 502 on the ground is cancelled, so that the moving wheel 6 is in contact with the ground, so that the mold frame can be flexibly moved to the required position, thereby improving the practicality and safety of the mold frame. At the same time, through the arrangement of the telescopic cylinder 4, the telescopic arm 401 in the telescopic cylinder 4 is extended and retracted, thereby driving the up and down movement of the lifting mechanism 3, which is beneficial to the height adjustment of the upper mold frame 2 and improves practicality.

[0023] The lifting mechanism 3 includes a support member 305 arranged on the side surface parallel to the telescopic direction of the telescopic cylinder 4 inside the lower mold frame 1, and the support member 305 is vertically provided with a rotatably connected guide sleeve 302, and the guide sleeve 302 is connected with a gear 303 at the middle position between the support members 305, and the gear 303 is fixedly connected to the guide sleeve 302, and the guide sleeve 302 is internally threadedly connected with a threaded rod 301, and the top end of the threaded rod 301 is inserted into the bottom surface of the upper mold frame 2 and connected thereto. Through the set lifting mechanism 3, when the telescopic arm 401 moves, the telescopic arm 401 drives the rack 402 to move forward and backward, thereby driving the gear 303 meshing with the rack 402 to rotate, thereby driving the guide sleeve 302 to rotate, so that the threaded rod 301 moves up and down relative to the guide sleeve 302, so that the upper mold frame 2 can move up and down, which is convenient for adjusting the height of the upper mold frame 2 and improving practicality.

[0024] A square groove 101 penetrating the side wall of the lower mold frame 1 is provided at a position corresponding to the support member 305. The protruding end of the gear 303 on one side close to the square groove 101 passes through the square groove 101 and meshes with the rack 402, so that the movement of the rack 402 can drive the rotation of the gear 303, thereby completing the height adjustment of the upper mold frame 2 by the lifting mechanism 3.

[0025] The rack 402 can move forward and backward in the long slot 403, and the protruding end of the rack 402 is flush with the corresponding outer side of the long slot 403, thereby ensuring that the telescopic arm 401 can move forward and backward in the telescopic cylinder 4 smoothly and unhindered, ensuring the normal use of the equipment.

[0026] The upper surface and the lower surface of the gear 303 are both provided with bearings 304, and the bearings 304 are both located between the support members 305.

The limit ring 7 is set to further ensure the stable rotation of the guide sleeve 302, thereby improving the stability of the upper mold frame 2 during height adjustment.

[0028] Working principle: when the mold frame needs to be used, first control the extension of the telescopic arm 401 in the telescopic cylinder 4, thereby driving the movement of the support mechanism 5 at the end of the telescopic arm 401. After moving to the appropriate position, control the extension of the hydraulic cylinder 501 to move the support base 502 downward, so that the support base 502 is fully in contact with the ground, and the moving wheel 6 is suspended, thereby increasing the overall support area of ​​the mold frame and ensuring the stability of the mold frame during use. When the mold frame needs to be moved, cancel the support of the support base 502 on the ground, so that the moving wheel 6 contacts the ground, so that the mold frame can be flexibly moved to the required position, thereby improving the practicality and safety of the mold frame. At the same time, during the extension and retraction of the telescopic arm 401, the telescopic arm 401 drives the rack 402 to move forward and backward, thereby driving the gear 303 meshing with the rack 402 to rotate, thereby driving the rotation of the guide sleeve 302, so that the threaded rod 301 moves up and down relative to the guide sleeve 302, so that the upper mold frame 2 can move up and down, which is convenient for adjusting the height of the upper mold frame 2 and improving practicality.
