Description

Technical Field

[0001] This utility model belongs to the field of mold processing technology, and specifically relates to a fixing device for mold processing. Background Technology

[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of the object by changing the physical state of the material being formed. Mold manufacturing requires a fixing device for stability.

[0003] Existing fixing devices mostly rely on manual pins, magnetic blocks, or single-size grooves for positioning, which can only be adapted to specific mold specifications. Furthermore, the mold is prone to displacement due to impact or vibration during processing, resulting in a decrease in processing accuracy. At the same time, existing fixing devices mostly only achieve clamping in one direction and cannot fix the mold from all sides in multiple dimensions, resulting in uneven force distribution.

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. Example

[0024] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0025] A fixing device for mold processing includes: an adjusting mechanism 1 and a fixing mechanism 2. The adjusting mechanism 1 includes a support base 101, on the surface of which two first electric cylinders 102 for longitudinal adjustment are mounted. A movable seat 103 is mounted on the surface of the piston rod of the first electric cylinders 102. The fixing mechanism 2 includes a rotating seat 201 rotatably connected to the upper surface of the movable seat 103. Two second electric cylinders 202 are mounted on the surface of the rotating seat 201, and a first clamping plate 203 is mounted on the surface of the piston rod of the second electric cylinders 202. A fixing seat 206 is provided on the inner side of the rotating seat 201 for fixing. The surface of the base 206 has two sliding grooves 207, and the surface of the sliding grooves 207 is rotatably connected to the second clamping plate 208. The inside of the fixed base 206 is rotatably connected to the drive shaft 209. The mold is placed through the fixed base 206, and then the drive shaft 209 rotates to drive the second clamping plate 208 to move. At this time, the second clamping plate 208 clamps the mold from both sides. Then, the second electric cylinder 202 starts its piston rod to drive the first clamping plate 203 to move. At this time, the mold can be clamped from all sides, thereby adapting to molds of different sizes and reducing the probability of mold slippage.

[0026] Specifically, the surface of the support base 101 is provided with a plurality of longitudinally extending guide rails 104, and the surface of the movable base 103 is rotatably connected with guide wheels 105 that contact the guide rails 104.

[0027] In a specific embodiment of this utility model, the guide wheel 105 is moved by the movement of the movable seat 103. At this time, the guide wheel 105 moves on the surface of the guide rail 104, thereby increasing the stability of the movable seat 103 when it moves.

[0028] Specifically, a first servo motor 106 is installed at the bottom of the movable seat 103. The surface of the output shaft of the first servo motor 106 and the bottom of the rotating seat 201 are both fixedly connected to timing wheels 107, and the two timing wheels 107 are rotatably connected through timing belts 108.

[0029] In a specific embodiment of this utility model, the first servo motor 106 starts its output shaft to drive a timing wheel 107 to rotate. At this time, under the action of the timing belt 108, another timing wheel 107 and the rotating seat 201 are driven to rotate.

[0030] Specifically, the inner surface of the first clamping plate 203 is provided with two spring telescopic rods 204, and the inner side of the spring telescopic rods 204 is provided with a rubber plate 205.

[0031] In a specific embodiment of this utility model, when the first clamping plate 203 moves, it will drive the spring telescopic rod 204 and the rubber plate 205 to move. When the rubber plate 205 contacts the mold, it will increase the force on it under the action of the spring telescopic rod 204.

[0032] Specifically, a transmission gear 210 is mounted on the surface of the transmission shaft 209, a second servo motor 211 is mounted on one side of the fixed base 206, a drive gear 212 is mounted on the surface of the output shaft of the second servo motor 211, and the drive gear 212 meshes with the transmission gear 210. The upper surface of the transmission shaft 209 is provided with a thread, and the bottom of the second clamping plate 208 is provided with a threaded groove that is compatible with the thread.

[0033] In a specific embodiment of this utility model, the output shaft of the second servo motor 211 is started to drive the drive gear 212 to rotate. At this time, the transmission gear 210 drives the transmission shaft 209 to rotate, and then the second clamping plate 208 is moved under the action of the thread and the thread groove.

[0034] Specifically, the surface of the sliding groove 207 is provided with a protrusion 213, and the surface of the second clamping plate 208 is provided with a groove 214 adapted to the protrusion 213.

[0035] In a specific embodiment of this utility model, when the second clamping plate 208 moves, the protrusion 213 moves and slides on the inner wall of the groove 214, thereby better guiding the second clamping plate 208.

[0036] Working principle: The mold is placed on the fixed base 206. The output shaft of the second servo motor 211 drives the drive gear 212 to rotate. At this time, the transmission gear 210 drives the transmission shaft 209 to rotate. Then, under the action of the thread and the thread groove, the second clamping plate 208 moves and clamps the mold from both sides. Then, the piston rod of the second electric cylinder 202 drives the first clamping plate 203 to move. When the first clamping plate 203 moves, it drives the spring telescopic rod 204 and the rubber plate 205 to move. At this time, the mold can be clamped from all sides, thus adapting to molds of different sizes and reducing the probability of mold slippage. The height of the mold can be adjusted by starting the first electric cylinder 102. The output shaft of the first servo motor 106 drives one timing wheel 107 to rotate. At this time, under the action of the timing belt 108, another timing wheel 107 and the rotating base 201 rotate, thereby adjusting the angle of the mold.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
