Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically a positioning fixture for automotive mold processing. Background Technology

[0002] In the process of automotive mold processing, in order to ensure the processing accuracy, production efficiency, and mold quality, the automotive mold is generally placed on a positioning fixture for clamping. The positioning fixture achieves precise positioning by restricting the workpiece's degrees of freedom and can also determine the reference position during processing. Mold processing usually involves multiple processes such as milling, electrical discharge machining, and grinding. If the positioning reference of each process is inconsistent, it will lead to the accumulation of errors. The positioning fixture ensures that the processing reference of each process is consistent by using a unified reference (such as the bottom surface and two sides of the mold as references), thereby improving the processing accuracy, stability, and production efficiency of automotive molds during processing.

[0003] However, in practice, it has been noted that most automotive molds are currently fixed in a bench vise during processing. Larger molds are positioned and clamped using a screw clamping mechanism. However, since a mold does not necessarily have only one side, when clamping the side of an automotive mold, only one side is usually clamped. During processing, due to the limited number of clamping points, it is very easy to cause shaking, which affects the clamping effect on the automotive mold. Utility Model Content

[0004] The purpose of this invention is to provide a positioning fixture for automotive mold processing. Symmetrically arranged rack and pinion rods are fitted with mutually engaging adjusting gears. This allows the ends of the rack and pinion rods to be aligned with the side of the mold. Furthermore, the adjusting gears enable the two rack and pinion rods to engage, allowing each rod to individually conform to different planes on the side of the mold, thus improving the positioning effect of the automotive mold. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning fixture for processing automotive molds includes an equipment base, a worktable fixedly connected to the top of the equipment base, T-shaped slide grooves arranged in a rectangular array on the worktable, a fixed slide block fixedly connected above the worktable, a hollow shell slidably fitted on the fixed slide block, and a double-point clamping device movably connected in the hollow shell.

[0007] The dual-point clamp includes a U-shaped slide block inserted into the inner side of the hollow shell. The end of the U-shaped slide block is movably connected to an adjusting gear. Both sides of the adjusting gear are equipped with rack push rods that slide with the sides of the hollow shell.

[0008] As a further technical solution of this utility model, an electric push rod is fixedly connected to the end of the U-shaped slide, and the electric push rod is located at the end of the hollow shell.

[0009] Each of the rack push rods is provided with a tapered positioning head at its end, and a limiting baffle that is fixedly connected to the hollow shell is slidably fitted in the tapered positioning head.

[0010] As a further technical solution of this utility model, the fixed slide includes a fixed base plate located below the hollow shell, and a dovetail-shaped slider is symmetrically fixedly connected to the bottom of the hollow shell. The fixed base plate is provided with a dovetail-shaped groove corresponding to the dovetail-shaped slider, and the dovetail-shaped slider and the dovetail-shaped groove slide in a sliding fit.

[0011] As a further technical solution of this utility model, the fixed base plate is provided with countersunk bolt holes symmetrically at one end away from the dovetail groove, and a locking bolt is inserted into each countersunk bolt hole, and a T-shaped limiting block is threaded at the end of the locking bolt.

[0012] As a further technical solution of this utility model, the T-shaped limiting block is located below the fixed base plate, and the T-shaped limiting block slides with the inner side of the T-shaped slide groove, and the end of the locking bolt extends through the workbench to the inner side of the T-shaped slide groove.

[0013] As a further technical solution of this utility model, a protective cover is fixedly connected to the top of the equipment base, and a linear processing mechanism module is fixedly connected to both sides of the protective cover, and the linear processing mechanism module is located above the worktable.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, an electric push rod drives a U-shaped slide to move, and the adjusting gear at the end of the U-shaped slide drives the rack push rods on both sides to move simultaneously until the ends of the rack push rods are in contact with the mold surface. The engagement between the adjusting gear and the rack push rods is used to clamp and position the mold surface.

[0016] 2. In this utility model, when the side of the mold is uneven or has multiple edge surfaces, one of the rack ejectors is pressed against the side of the mold. At this time, the electric push rod will continue to push the U-shaped slide to move. Since one rack ejector is fixed, the adjusting gear will rotate. Through the transmission cooperation between the adjusting gear and the rack ejector, the other rack ejector will be pushed to continue to move forward until both rack ejectors are in contact with the mold surface, thereby improving the positioning effect of the mold.

[0017] 3. According to the mold size, first loosen the locking bolts and adjust the position of the fixed base plate above the worktable. At this time, the T-shaped limit block moves inside the T-shaped slide along with the locking bolts and makes the fixed slide symmetrically set on both sides of the mold. Then tighten the locking bolts and fix the position of the fixed base plate above the worktable through the threaded engagement between the locking bolts and the T-shaped limit block.

Detailed Implementation

[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] Please see Figure 1-6This utility model provides a positioning fixture for automobile mold processing, including a device base 1, a worktable 4 fixedly connected to the top of the device base 1, and T-shaped slide grooves 8 arranged in a rectangular array on the worktable 4. A fixed slide block 5 is also fixedly connected above the worktable 4, and a hollow shell 7 is slidably fitted on the fixed slide block 5. A double-point clamping device 6 is movably connected in the hollow shell 7.

[0028] The dual-point clamping device 6 includes a U-shaped slide 62 inserted into the inner side of the hollow shell 7. The end of the U-shaped slide 62 is movably connected to an adjusting gear 63. Both sides of the adjusting gear 63 are driven by rack push rods 64 that slide with the sides of the hollow shell 7.

[0029] By adopting the above technical solution, the electric push rod 61 pushes the U-shaped slide 62 to move, and the adjusting gear 63 at the end of the U-shaped slide 62 drives the rack push rods 64 on both sides to move simultaneously until the end of the rack push rod 64 is in contact with the mold surface. The engagement between the adjusting gear 63 and the rack push rod 64 is used to clamp and position the mold surface.

[0030] Furthermore, an electric push rod 61 is fixedly connected to the end of the U-shaped slide 62, and the electric push rod 61 is located at the end of the hollow shell 7.

[0031] Each of the rack push rods 64 has a tapered positioning head 65 at its end, and a limiting baffle 67 that is fixedly connected to the hollow shell 7 is slidably fitted in the tapered positioning head 65.

[0032] By adopting the above technical solution, when the side of the mold is uneven or has multiple edge surfaces, one of the rack ejector pins 64 is pressed against the side of the mold. At this time, the electric push rod 61 will continue to push the U-shaped slide block 62 to move. Since one of the rack ejector pins 64 is fixed, the adjusting gear 63 will rotate. Through the transmission cooperation between the adjusting gear 63 and the rack ejector pin 64, the other rack ejector pin 64 is pushed to continue to move forward until both rack ejector pins 64 are in contact with the mold surface, thereby improving the positioning effect of the mold.

[0033] Furthermore, the fixed slide block 5 includes a fixed base plate 51 located below the hollow shell 7, and a dovetail-shaped slider 71 is symmetrically fixedly connected to the bottom of the hollow shell 7. The fixed base plate 51 is provided with a dovetail-shaped groove 52 corresponding to the dovetail-shaped slider 71, and the dovetail-shaped slider 71 and the dovetail-shaped groove 52 slide in cooperation.

[0034] More specifically, the fixed base plate 51 has countersunk bolt holes 55 symmetrically opened at one end away from the dovetail groove 52. Each countersunk bolt hole 55 is fitted with a locking bolt 54, and the end of the locking bolt 54 is threaded with a T-shaped limit block 53.

[0035] Furthermore, the T-shaped limiting block 53 is located below the fixed base plate 51, and the T-shaped limiting block 53 slides in cooperation with the inner side of the T-shaped slide groove 8, and the end of the locking bolt 54 extends through the worktable 4 to the inner side of the T-shaped slide groove 8.

[0036] By adopting the above technical solution, according to the mold size, first loosen the locking bolt 54, adjust the position of the fixed base plate 51 above the worktable 4, at this time the T-shaped limit block 53 moves with the locking bolt 54 inside the T-shaped slide 8, and make the fixed slide 5 symmetrically set on both sides of the mold. Then tighten the locking bolt 54, and fix the position of the fixed base plate 51 above the worktable 4 through the threaded engagement between the locking bolt 54 and the T-shaped limit block 53.

[0037] Furthermore, a protective cover 2 is fixedly connected to the top of the equipment base 1, and a linear processing mechanism module 3 is fixedly connected to both sides of the protective cover 2, and the linear processing mechanism module 3 is located above the worktable 4.

[0038] Furthermore, the electric push rod 61 is fixedly connected above the fixed base plate 51, and the end of the electric push rod 61 extends through the hollow shell 7 to the inside of the hollow shell 7, so that the electric push rod 61 can push the U-shaped slide 62 inside the hollow shell 7 to move.

[0039] Furthermore, both ends of the rack push rod 64 extend through the hollow outer shell 7 to both ends of the hollow outer shell 7, and both ends of the limiting baffle 67 on the inner side of the strip groove 66 are bolted to the hollow outer shell 7, thereby limiting the rack push rod 64 through the sliding cooperation between the strip groove 66 and the limiting baffle 67.

[0040] The working principle of this utility model is as follows: During use, according to the mold size, first loosen the locking bolt 54 and adjust the position of the fixed base plate 51 above the worktable 4. At this time, the T-shaped limit block 53 moves along the inner side of the T-shaped slide 8 following the locking bolt 54. Then, tighten the locking bolt 54. Through the threaded engagement between the locking bolt 54 and the T-shaped limit block 53, the position of the fixed base plate 51 above the worktable 4 is fixed. Then, place the car mold above the worktable 4, with the car mold positioned between the two fixed slide blocks 5. Then, the electric push rod 61 pushes the U-shaped slide block 62 to move, and the adjusting gear 63 at the end of the U-shaped slide block 62 drives the rack push rods 64 on both sides to simultaneously move towards the car mold until the ends of the rack push rods 64 are in contact with the mold surface. Furthermore, the car mold is clamped and positioned by the meshing between the adjusting gear 63 and the rack and pinion rod 64. When the side of the car mold is uneven, one of the rack and pinion rods 64 first comes into contact with the side of the mold. At this time, the electric push rod 61 will continue to push the U-shaped slide 62 to move. Since one of the rack and pinion rods 64 is fixed, the adjusting gear 63 at the end of the U-shaped slide 62 will rotate when the U-shaped slide 62 moves. Through the transmission cooperation between the adjusting gear 63 and the rack and pinion rod 64, the other rack and pinion rod 64 is pushed to continue to move forward until both rack and pinion rods 64 are in contact with the side of the mold, thereby fixing the car mold and improving the positioning effect of the mold. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
