Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary support structure, and more particularly to an auxiliary support structure for molds. Background Technology
[0002] In mold manufacturing, stable mold support is a key factor in ensuring machining accuracy and product quality. Traditional mold support structures often use fixed clamping methods, which can only fix the mold in a single direction or with limited support, making it difficult to achieve omnidirectional stable clamping in the vertical and horizontal directions. During machining, the mold is prone to shaking due to uneven force or external interference, leading to dimensional deviations, decreased surface quality, and severely affecting the mold's machining accuracy and service life, greatly limiting production efficiency and product quality improvement.
[0003] Meanwhile, different types and specifications of molds vary significantly in size and height. Existing mold support structures offer limited height adjustment capabilities, mostly allowing only rough adjustments to the overall height and failing to precisely adapt to the specific height of the mold base. This necessitates frequent replacement of support equipment or the addition of auxiliary height-raising devices when dealing with molds of varying heights. This not only results in cumbersome and inefficient operations but also increases production costs and equipment maintenance difficulty, making it difficult to meet the actual needs of diverse mold production.
[0004] Therefore, there is an urgent need for a mold auxiliary support structure that can achieve efficient and stable clamping and fixation, while also having flexible height adjustment function, in order to solve the above-mentioned problems in the existing technology. Utility Model Content
[0005] To overcome the aforementioned drawbacks, the technical problem is to provide an auxiliary support structure for molds.
[0006] The technical solution is as follows: An auxiliary support structure for a mold includes a base, a frame, a support platform, a sliding block, a sliding frame, a clamping block, a second screw, a positioning plate, a third screw, and a drive assembly. The frame is placed on top of the base, and the support platform is connected to the top of the frame. Sliding blocks are slidably connected to the left, right, front, and rear sides of the support platform. The sliding frame is connected to the top of the sliding blocks. A clamping block is slidably connected to the sliding frame. A second screw is rotatably connected to the sliding frame and threadedly connected to the clamping block. A positioning plate is slidably connected to the top of the clamping block. Two third screws are rotatably connected to the positioning plate and threadedly connected to the corresponding clamping blocks. A drive assembly is provided at the bottom of the support platform.
[0007] Optionally, a rubber pad is provided on the inner side of the clamping block.
[0008] Optionally, both the second and third screws may use trapezoidal threads with a thread angle of 30°.
[0009] Optionally, the drive assembly includes a rotating shaft, a turntable, a worm gear, and a worm. The rotating shaft is rotatably connected to the bottom of the support platform, and the turntable is connected to the rotating shaft. Four arc-shaped grooves are opened along the circumference of the turntable, and the sliding block slides in cooperation with the corresponding arc-shaped groove. The lower end of the rotating shaft is connected to the worm gear, and the right side of the frame is rotatably connected to the worm gear, which meshes with the worm gear. The front end of the worm gear passes through the frame to form an operating end.
[0010] Optionally, the walls of the arc-shaped groove in the turntable are smooth, and the surface roughness Ra is not greater than 0.8 μm.
[0011] Optionally, it also includes a first screw and a knob. The first screw is symmetrically rotatably connected to the top of the base. The first screw is threadedly connected to the frame. The knob is connected to the top of the first screw. Grooves are provided on both sides of the frame at positions corresponding to the knob to facilitate operation of the knob.
[0012] The beneficial effects of this utility model are: 1. Through the linkage of the worm gear, worm wheel, rotating shaft and turntable in the drive assembly, the four sliding blocks can move synchronously, driving the clamping block and positioning plate to fix the mold base in both the upper and lower and side directions, ensuring that the mold is stable in the processing process, effectively preventing the processing accuracy deviation caused by mold shaking, and improving the processing quality and stability.
[0013] 2. The first screw and knob structure between the base and the frame can easily adjust the height of the frame to meet the support requirements of molds of different heights; at the same time, the third screw on the clamping block can drive the positioning plate to move up and down to adapt to the height of the mold base of different sizes, so that the device has good versatility and reduces the equipment adjustment cost caused by differences in mold specifications.

Detailed Implementation
[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings.
[0020] Example: An auxiliary support structure for a mold, such as Figures 1-4 As shown, the device includes a base 1, a frame 2, a support platform 3, sliding blocks 10, a sliding frame 11, a clamping block 12, a second screw 13, a positioning plate 14, a third screw 15, and a drive assembly. The frame 2 is placed on top of the base 1, and the support platform 3 is connected to the top of the frame 2. Sliding blocks 10 are slidably connected to the left, right, front, and rear sides of the support platform 3, respectively. The sliding frame 11 is connected to the top of the sliding blocks 10, and the clamping block 12 is slidably connected to the sliding frame 11. A rubber pad is provided on the inner side of the clamping block 12 to increase the clamping block 12's contact with the mold bottom. The friction between the supports acts as a buffer. A second screw 13 is rotatably connected to the sliding frame 11. The second screw 13 is threadedly connected to the clamping block 12. A positioning plate 14 is slidably connected to the top of the clamping block 12. Two third screws 15 are rotatably connected to the positioning plate 14. The two third screws 15 are threadedly connected to the corresponding clamping blocks 12. Both the second screw 13 and the third screw 15 adopt trapezoidal threads. The tooth angle of the trapezoidal thread is 30°, which has good self-locking performance and transmission efficiency. A drive assembly is provided at the bottom of the support platform 3.
[0021] like Figures 1-2 As shown, the drive assembly includes a rotating shaft 6, a turntable 7, a worm gear 8, and a worm 9. The rotating shaft 6 is rotatably connected to the bottom of the support platform 3, and the turntable 7 is connected to the rotating shaft 6. The turntable 7 has four arc-shaped grooves along its circumference. The sliding block 10 slides in cooperation with the corresponding arc-shaped groove. The groove walls of the arc-shaped grooves are smooth, and the surface roughness Ra is not greater than 0.8μm to ensure that the sliding block 10 can slide smoothly in the arc-shaped groove. The lower end of the rotating shaft 6 is connected to the worm gear 8, and the right side of the frame 2 is rotatably connected to the worm 9 that meshes with the worm gear 8. The front end of the worm 9 passes through the frame 2 to form an operating end. By rotating the worm 9, the worm 9 drives the worm gear 8 that meshes with it to rotate, thereby causing the rotating shaft 6 and the turntable 7 to rotate. During the rotation of the turntable 7, the arc-shaped grooves on it push the sliding block 10 to move closer to each other, thereby driving the sliding frame 11, the clamping block 12, and the positioning plate 14 to move synchronously, which can achieve clamping of the four sides of the mold base.
[0022] like Figures 1-2 As shown, it also includes a first screw 4 and a knob 5. The first screw 4 is symmetrically rotatably connected to the top of the base 1. The first screw 4 is threadedly connected to the frame 2. The knob 5 is welded to the top of the first screw 4. Grooves are provided on both sides of the frame 2 at positions corresponding to the knob 5 to facilitate the operation of the knob 5. By rotating the knob 5, the first screw 4 is driven to rotate. The threaded engagement between the first screw 4 and the frame 2 allows the frame 2 to be adjusted in the vertical direction, thereby meeting the support requirements of different molds.
[0023] Under normal operating conditions, the four clamping blocks 12 are arranged in a square pattern, suitable for clamping square molds. When clamping the mold is required, the worm gear 9 can be rotated to rotate the turntable 7, controlling the synchronous movement of the four sliding blocks 10. The clamping blocks 12 move closer together to clamp the four sides of the mold base, while the positioning plate 14 presses down on the top of the mold base, completing the double fixation of the mold in both the vertical and horizontal directions. Since the base height of different molds varies, it can be adjusted by rotating the third screw 15. The third screw 15 is threadedly connected to the clamping blocks 12. When rotated, it moves up or down along the clamping blocks 12, thereby driving the positioning plate 14 to move synchronously, thus adjusting the height of the positioning plate 14 and improving the applicability of the device to different molds. When dealing with rectangular molds, the distribution shape of the clamping blocks 12 can be changed. The specific operation involves adjusting the left and right or front and rear clamping blocks 12 individually, rotating the second screw 13, and the second screw 13 driving the clamping blocks 12 to move and adjust along the sliding frame 11. The positioning plate 14 also moves synchronously, thereby changing the distribution of the clamping blocks 12 and achieving clamping of the rectangular mold.
