Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold manufacturing fixtures, specifically to a fixing fixture used in mold manufacturing. Background Technology
[0002] Mold manufacturing is a key process in industrial production for shaping or processing materials. It involves multiple stages such as design, processing, assembly, and debugging, ultimately producing molds with specific shapes, sizes, and functions. Molds are widely used in injection molding, stamping, die casting, forging, and other processing scenarios. They are core tools for achieving mass production and high precision in industries such as automobiles, electronics, home appliances, and aerospace. Fixtures used in mold manufacturing are special devices used to fix workpieces, mold components, or processing equipment during the mold manufacturing process. Through precise positioning and clamping, they ensure the stability of mold parts during processing and avoid dimensional deviations caused by vibration and thermal deformation.
[0003] Existing mold manufacturing fixtures lack self-adaptive clamping capabilities, leading to low efficiency when manually adjusting the clamping range using bolts and shims to adapt to molds of different sizes. Furthermore, they are prone to inaccurate positioning due to human error. Fixed fixtures are typically designed for specific molds, resulting in poor versatility and difficulty in meeting the production needs of multiple mold models.
[0004] Therefore, it is necessary to invent a fixing fixture for mold manufacturing to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a fixing fixture for mold manufacturing. Through a bidirectional screw, threaded sleeve, trapezoidal push block, main telescopic plate, extension plate, telescopic cylinder, and contact clamping head, the fixing fixture for mold manufacturing possesses self-adaptive clamping capabilities. This design automatically centers and clamps, adapting to molds of different sizes without requiring manual measurement and adjustment, thus solving the problem of frequent adjustments required by traditional fixtures. Furthermore, the four-point fixing structure formed by the telescopic cylinder and contact clamping head enhances clamping force while also achieving multi-dimensional adjustment and precision assurance. This improves the self-adaptive capability, clamping stability, and durability of the fixing fixture for mold manufacturing. This addresses the problem that existing fixing fixtures for mold manufacturing lack self-adaptive clamping capabilities, leading to inefficiency when manually adjusting the clamping range using bolts and shims to adapt to different mold sizes, and are prone to inaccurate positioning due to human error. Moreover, fixed fixtures are typically designed for specific molds, lacking versatility and failing to meet the production needs of multiple mold models.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for mold manufacturing, including a fixture base and a clamping body for mold manufacturing; A clamping groove is located at the center above the fixture seat for adjusting the spacing. A micro motor is fixedly installed on the outside of the clamping groove. A bidirectional screw is fixedly installed at the output end of the micro motor. A threaded sleeve is connected to the external thread of the bidirectional screw. A wheel is fixedly installed at the other end of the bidirectional screw. A trapezoidal push block is fixedly installed above the threaded sleeve. Side-contact mounting plates are fixedly installed on both sides of the fixture seat for auxiliary installation. Positioning bolts are threaded through the upper sides of the side-contact mounting plates. A main telescopic plate is fixedly installed on the upper side of the side-contact mounting plates. An extension plate is slidably connected inside the main telescopic plate. A fixing knob is threaded through the outer side of the main telescopic plate. A telescopic cylinder is fixedly installed on the top of the extension plate. A contact clamping head is fixedly installed at the front end of the telescopic cylinder.
[0007] Preferably, the threaded sleeve is slidably connected to the clamp seat, and the threads of the bidirectional screw are opposite in direction.
[0008] Preferably, a middle spacer is fixedly installed in the center of the clamping groove, inner sliding grooves are opened on both sides of the clamping groove, and an inner slider is fixedly installed on the outside of the threaded sleeve.
[0009] Preferably, the trapezoidal push block has an installation groove on its upper part, and a support plate is threaded into the installation groove.
[0010] Preferably, a telescopic buffer spring is fixedly installed between the outside of the abutting clamping head and the extension plate, and the abutting clamping head is telescopically connected to the extension plate.
[0011] Preferably, the mold body is placed above the support plate, and the abutting clamping head is symmetrically arranged with respect to the central axis of the clamping seat.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model incorporates a bidirectional screw, threaded sleeve, trapezoidal push block, main telescopic plate, extension plate, telescopic cylinder, and abutment clamping head. When using a fixing fixture manufactured from this mold, the trapezoidal push block can be driven to move towards the center due to the varying sizes of the mold body. This clamps the mold body placed on the trapezoidal push block. The height of the main telescopic plate and extension plate on both sides is then adjusted, allowing the telescopic cylinder to drive the abutment clamping head to abut against the outer sides of the mold body. This four-point clamping mechanism provides the mold-manufacturing fixing fixture with self-adaptive clamping capabilities. This design, through automatic centering clamping, adapts to molds of different sizes, eliminating the need for manual measurement and adjustment, thus solving the problem of frequent adjustments required by traditional fixtures. Furthermore, the four-point fixing structure formed by the telescopic cylinder and abutment clamping head enhances clamping force while also achieving multi-dimensional adjustment and precision assurance. This improves the self-adaptive capability, clamping stability, and durability of the mold-manufacturing fixing fixture. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figure 1-5 The fixture shown includes a fixture base 1 and a clamping body for mold manufacturing; The clamping groove 2 is located at the center above the clamping seat 1 and is used for spacing adjustment. A micro motor 3 is fixedly installed on the outside of the clamping groove 2. A bidirectional screw 4 is fixedly installed at the output end of the micro motor 3. A threaded sleeve 5 is connected to the external thread of the bidirectional screw 4. A wheel 6 is fixedly installed at the other end of the bidirectional screw 4. A trapezoidal push block 10 is fixedly installed above the threaded sleeve 5. Side contact mounting plates 13 are fixedly installed on both sides of the fixture base 1 for auxiliary installation. Positioning bolts 14 are threaded through the upper sides of the side contact mounting plates 13. A main telescopic plate 15 is fixedly installed on the upper side of the side contact mounting plates 13. An extension plate 16 is slidably connected inside the main telescopic plate 15. A fixing knob 17 is threaded through the outer side of the main telescopic plate 15. A telescopic cylinder 18 is fixedly installed on the top of the extension plate 16. An abutment clamping head 19 is fixedly installed at the front end of the telescopic cylinder 18. The trapezoidal push block 10 can be driven to move towards the middle by the bidirectional screw 4, thereby clamping the mold body 21 placed on the trapezoidal push block 10. Then, the height of the main telescopic plates 15 and the extension plate 16 on both sides is adjusted so that the telescopic cylinder 18 drives the abutment clamping head 19 to abut against the outer sides of the mold body 21. In this way, the mold is clamped by four points, and the fixed fixture for mold manufacturing also has the ability to self-clamp.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the threaded sleeve 5 is slidably connected to the clamping seat 1. The threads of the bidirectional screw 4 are opposite in direction. The bidirectional screw 4 can drive the two threaded sleeves 5 to drive the trapezoidal push block 10 to slide in the center at the same frequency, thereby clamping molds of different sizes. A middle spacer 7 is fixedly installed in the center of the clamping groove 2. Inner sliding grooves 8 are opened on both sides of the clamping groove 2. An inner slider 9 is fixedly installed on the outside of the threaded sleeve 5. The inner sliding grooves 8 and the inner slider 9 are used to limit the running trajectory of the threaded sleeve 5 on the clamping groove 2, so that the threaded sleeve 5 slides stably in the center. An installation groove 11 is opened above the trapezoidal push block 10. A support plate 12 is threadedly connected inside the installation groove 11. The support plate 12 is used to place the mold and clamp and fix the bottom side of the mold of different sizes.
[0019] like Figure 1 , Figure 4 and Figure 5As shown, a telescopic buffer spring 20 is fixedly installed between the outside of the clamping head 19 and the extension plate 16. The clamping head 19 is telescopically connected to the extension plate 16. The telescopic buffer spring 20 generates elastic deformation during the clamping process, effectively absorbing dynamic loads such as cutting vibration and thermal deformation, and avoiding surface damage or positioning displacement of the mold body 21 caused by rigid impact. The mold body 21 is placed on the support plate 12. The clamping head 19 is symmetrically arranged with respect to the central axis of the fixture seat 1. The support plate 12 and the trapezoidal push block 10 are in surface-to-surface contact support. Combined with the point-to-surface clamping of the clamping head 19, a dual positioning system of support + clamping is formed.
[0020] The working principle of this practical application is as follows: First, connect the external power supply and place the mold-making fixture on the mold-making equipment. Secure the fixture to the equipment using the side contact mounting plate 13 and positioning bolts 14. Then, based on the current size of the mold body 21, rotate the bidirectional screw 4 via the micro motor 3. The bidirectional screw 4 then moves the trapezoidal push block 10 towards the center, clamping the mold body 21 placed on the support plate 12. Next, adjust the height of the main telescopic plates 15 and extension plates 16 on both sides by turning the fixing knob 17, making them flush with the mold body 21. Then, open the telescopic cylinder 18, causing the contact clamping head 19 to contact the outer sides of the mold body 21. This four-point fixation completes the clamping of the mold. The telescopic buffer spring 20 undergoes elastic deformation during clamping, effectively absorbing... The fixture absorbs dynamic loads such as cutting vibration and thermal deformation, avoiding surface damage or positioning displacement of the mold body 21 caused by rigid impact. This also gives the mold manufacturing fixture an adaptive clamping capability. This design automatically centers and clamps, adapting to molds of different sizes without the need for manual measurement and adjustment, solving the problem of frequent adjustments required by traditional fixtures. In addition, the four-point fixing structure composed of telescopic cylinder 18 and abutment clamping head 19 enhances the clamping force while also meeting the purpose of multi-dimensional adjustment and precision assurance. After the preparation work is completed, external equipment can be used to manufacture the mold after clamping. Finally, after completing the installation and use of all the mold manufacturing fixtures according to the above operations, turn off the switch of micro motor 3 and the switch of telescopic cylinder 18. If not used for a long time, simply disconnect the external power supply. This completes the use of the fixture for mold manufacturing.
[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
