Description

Technical Field

[0001] This utility model relates to the field of mold frame tooling technology, specifically to mold frame tooling that can achieve flexible positioning. Background Technology

[0002] Tooling is a connection device used between equipment and workpiece. It is a positioning and clamping device for workpiece in machine tool equipment. Mold frame tooling is a semi-finished product of mold, composed of various steel plates and matching parts. It can be said to be the skeleton of the entire mold, that is, the support of the mold. Mold frame tooling is an inseparable part of the mold. At present, the precision requirements of mold frame will be determined according to different levels and product needs.

[0003] The prior art patent application number is 202323423899.1, and the patent name is: A mold frame tooling for easy positioning, which includes an upper mold frame and a lower mold frame. The upper mold frame has positioning rods fixedly installed at the four corners of its lower surface, and the lower mold frame has positioning holes at the four corners of its upper surface. The bottom of each of the four positioning holes is fixedly installed with a buffer assembly. Each of the four buffer assemblies includes a fixing plate. The upper surface of each of the four fixing plates is fixedly installed with a spring rod, and the upper surface of each of the four spring rods is fixedly installed with a spring damper. In this invention, the mold frame fixture uses a level to detect the horizontality of the lower mold frame, avoiding production errors. The positioning rod and positioning hole work together to raise the mold frame for the first positioning, and a laser light is used to illuminate the auxiliary hole for a second positioning, further enhancing the accuracy of mold closing. Through multiple positioning, the accuracy of mold frame positioning is improved, thus increasing the precision of parts production. However, the buffer mechanism structure is relatively simple and cannot effectively buffer the pressure from the upper mold frame. Furthermore, the existing mold frame fixture structure is relatively fixed and cannot stably fix the mold of the main body size, which has limitations in use. Therefore, we propose a mold frame fixture that can achieve flexible positioning. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Example 1: Please refer to again Figure 1-5 This utility model provides a mold frame fixture that enables flexible positioning, including a lower mold frame 100. Positioning holes 110 are formed at the four corners of the top of the lower mold frame 100. A base plate 120 is fixedly connected to the bottom of the inner cavity of the positioning holes 110. The buffer mechanism includes a damping cylinder 130, which is fixedly connected to the top of the base plate 120. A sealing ring 131 is adhered to the top of the damping cylinder 130. The inner cavity of the damping cylinder 130 is filled with damping oil 140. A pressure rod 15 is inserted into the top of the damping cylinder 130. 0. The bottom end of the pressure rod 150 passes through the damping cylinder 130 and extends into the inner cavity of the damping cylinder 130. The bottom end of the pressure rod 150 is fixedly connected to a seepage plate 151. The top of the seepage plate 151 has seepage holes 152 evenly distributed around its circumference. The top end of the pressure rod 150 is fixedly connected to a buffer plate 160. The top of the bottom plate 120 is fixedly connected to a buffer spring 170 evenly distributed around its circumference. The top end of the buffer spring 170 is fixedly connected to the buffer plate 160.

[0024] Specifically, when the positioning rod 242 on the upper mold frame 200 is inserted into the positioning hole 110 of the lower mold frame 100, the positioning rod 242 applies pressure to the buffer plate 160, causing the pressure rod 150 at the bottom of the buffer plate 160 to move, so that the seepage plate 151 squeezes the damping oil 140 in the damping cylinder 130, so that the damping oil 140 flows through the seepage hole 152 on the seepage plate 151 to the other side of the seepage plate 151. In this process, damping force is generated. At the same time, as the pressure rod 150 moves down, the distance between the buffer plate 160 and the bottom plate 120 decreases, so that the deformation of the buffer spring 170 between the buffer plate 160 and the bottom plate 120 is reduced. The seepage plate 151, which squeezes the damping oil 140, buffers the pressure applied by the upper mold frame 200 to the mold.

[0025] Example 2: Please refer to again Figure 1-5The adjustment mechanism includes an upper mold frame 200, which is located above the lower mold frame 100. The upper mold frame 200 has transmission chambers 210 on its left and right sides, and limit grooves 220 on its four sides. Sliding grooves 230 are also formed on the four sides of the upper mold frame 200, with the four sliding grooves 230 located outside the limit grooves 220. Adjustment frames 240 are slidably connected to the inner cavities of the four sliding grooves 230. The bottom of the adjustment frame 240 penetrates the upper mold frame 200 and extends to its bottom. A mounting plate 241 is fixedly connected between the bottom ends of the front and rear adjustment frames 240. Positioning rods 242 are fixedly connected to the front and rear sides of the bottom of the mounting plate 241. Gear driven screws 250 are rotatably connected to the front and rear side walls of the inner cavities of the left and right transmission chambers 210. The end of the driven screw 250 passes through the transmission chamber 210 and extends into the inner cavity of the limiting groove 220. Threaded sleeves 251 are screwed onto the outer walls of the driven screw 250 on both the front and rear sides. Tenons 252 are fixedly connected to the ends of the threaded sleeves 251 on both the front and rear sides. The ends of the tenons 252 on both the front and rear sides pass through the adjusting brackets 240 on both the front and rear sides and extend into the interior of the upper mold frame 200. A rotating rod 260 is rotatably connected to the left side wall of the upper mold frame 200. The right end of the rotating rod 260 passes through the left and right transmission chambers 210 on both the left and right sides and extends into the inner cavity of the right transmission chamber 210. The right end of the rotating rod 260 is rotatably connected to the right transmission chamber 210. Drive gears 261 are fixedly connected to the left and right sides of the outer walls of the rotating rod 260. The drive gears 261 mesh with the driven screws 250 on both the front and rear sides.

[0026] Specifically, when it is necessary to adjust the distance between the upper mold base 200 and the lower mold base 100 to fix molds of different sizes, the drive gear 261 on the rotating rod 260 is rotated to drive the driven screw 250 to rotate. The threaded sleeve 251 installed on the driven screw 250 moves with the rotation of the driven screw 250, and the tenon 252 installed on the threaded sleeve 251 moves into the limiting groove 220 to remove the limiting of the adjusting frame 240. Then the position of the adjusting frame 240 in the slide groove 230 is adjusted. After adjusting to the appropriate position, the rotating rod 260 is reversed to insert the tenon 252 into the positioning hole 110 of the adjusting frame 240 to limit and fix the adjusting frame 240.

[0027] Working principle: When the positioning rod 242 on the upper mold frame 200 is inserted into the positioning hole 110 of the lower mold frame 100, the positioning rod 242 applies pressure to the buffer plate 160, causing the pressure rod 150 at the bottom of the buffer plate 160 to move. This causes the seepage plate 151 to squeeze the damping oil 140 in the damping cylinder 130, allowing the damping oil 140 to flow through the seepage holes 152 on the seepage plate 151 to the other side of the seepage plate 151. During this process, damping force is generated. At the same time, as the pressure rod 150 moves downward, the distance between the buffer plate 160 and the bottom plate 120 decreases, reducing the deformation of the buffer spring 170 located between the buffer plate 160 and the bottom plate 120. This, combined with the pressure exerted by the seepage plate 151 on the damping oil 140, increases the pressure applied by the upper mold frame 200 to the mold. To buffer the impact, when it is necessary to adjust the distance between the upper mold base 200 and the lower mold base 100 to fix molds of different sizes, the drive gear 261 on the rotating rod 260 is rotated to drive the driven screw 250 to rotate. The threaded sleeve 251 installed on the driven screw 250 moves with the rotation of the driven screw 250, and the tenon 252 installed on the threaded sleeve 251 moves into the limiting groove 220 to release the limiting of the adjusting frame 240. Then the position of the adjusting frame 240 in the slide groove 230 is adjusted. After adjusting to the appropriate position, the rotating rod 260 is reversed to insert the tenon 252 into the positioning hole 110 of the adjusting frame 240 to limit and fix the adjusting frame 240.
