[0025] Reference Figure 1-Figure 4 , shows a precision mold anti-collision protection device of the utility model, which includes a mold box 10, wherein at least one group of relative inner walls of the mold box 10 is provided with a plurality of first airbags 21 arranged in parallel and transversely, and the plurality of first airbags 21 are respectively connected to first charging and discharging valves 25; at least one group of relative inner walls of the mold box 10 is provided with second airbags 31, and the second airbags 31 are connected to second charging and discharging valves 32;

[0027] In an embodiment of the present application, through the mold box 10, at least one group of relative inner walls of the mold box 10 is provided with a plurality of first air bags 21 arranged laterally and in parallel, and the plurality of first air bags 21 are respectively connected to first charging and discharging valves 25; at least one group of relative inner walls of the mold box 10 is provided with second air bags 31, and the second air bags 31 are connected to second charging and discharging valves 32; a controller 12 is provided on the side wall of the mold box 10, and the first charging and discharging valves 25 and the second charging and discharging valves 32 are respectively electrically connected to the controller 12; an elastic protection mechanism 40 is provided on the peripheral side of the outer wall of the mold box 10, and the elastic protection mechanism 40 is used to provide anti-collision protection against external collisions.

The present application can protect the mold during installation or transportation to prevent it from bumping and damaging the internal precision parts, can reduce the damage caused by external impact, play an anti-collision protection role, and provide all-round protection.

[0028] Next, the precision mold anti-collision protection device in this exemplary embodiment will be further described.

[0029] In the embodiment of the present application, at least one group of relative inner walls of the mold box 10 is provided with a plurality of first air bags 21 arranged transversely and in parallel, and the plurality of first air bags 21 are respectively connected to a first charging and discharging valve 25, that is, each first air bag 21 is independently controlled by a first charging and discharging valve 25, and the first charging and discharging valve 25 is electrically connected to the controller 12. The controller 12 controls the opening and closing time of the plurality of first charging and discharging valves 25, thereby independently controlling the charging and discharging time of the plurality of first air bags 21. When the plurality of transversely parallel first air bags 21 are slowly deflated from top to bottom in sequence, they can play a descending buffering role for the mold entering the mold box 10, thereby preventing damage to the internal precision parts caused by bumps or shaking.

[0030] As an example, the plurality of first airbags 21 are all located at the lower part of the inner wall of the mold box 10, and the upper part of the inner wall of the mold box 10 is provided with an induction sensor 13, and the induction sensor 13 is electrically connected to the controller 12, and the induction sensor 13 is used to detect whether the mold enters the mold box 10. The induction sensor 13 can be a photoelectric sensor. When the induction sensor 13 detects that the mold enters the mold box 10, or after a period of time (according to the distance between the first first airbag 21 and the top of the box, the time is set by the program), the controller 12 can control the plurality of first charging and discharging valves 25 to open and deflate in sequence. By setting the plurality of first airbags 21 at the lower part of the inner wall of the mold box 10, the mold can be directly placed at the lower part of the mold box 10 and then start to descend and buffer, so that the mold can remain stable when descending in the box.

[0031] As an example, the first airbag 21 is fixed to the inner wall of the mold box 10 through the first rubber pad 22. There is a mutual squeezing effect between the first airbag 21 and the mold. The first rubber pad 22 is arranged between the first airbag 21 and the inner wall of the box, which can play a certain protective role for the first airbag 21. The first airbag 21 is connected to a first branch pipe 23, and multiple first branch pipes 23 are connected to a first main pipe 24. The first branch pipe 23 and the first main pipe 24 are both located in the inner cavity of the side wall of the mold box 10; wherein, the first main pipe 24 passes through the side wall of the mold box 10 and is externally connected to the first charging and discharging interface 26, and multiple first charging and discharging valves 25 are respectively connected to multiple first branch pipes 23. The first inflation and deflation interface 26 can be a three-way interface, through which the inflation device and the deflation pipe are externally connected; when inflating, all the multiple first inflation and deflation valves 25 are opened, and the inflation device can inflate the multiple first airbags 21 at the same time through the first main pipe 24 and the multiple first branch pipes 23; when deflation, the multiple first inflation and deflation valves 25 are controlled to open in sequence through the controller 12, so that the multiple first airbags 21 are slowly deflated in sequence and discharged from the deflation pipe.

[0032] As an example, the cross section of the first airbag 21 is arc-shaped, and the arc structure makes the mold descending process smoother and unobstructed.

[0033] In the embodiment of the present application, at least one group of relative inner walls of the mold box 10 is provided with a second airbag 31, and the second airbag 31 is connected to a second charging and discharging valve 32, and the second charging and discharging valve 32 is electrically connected to the controller 12. The controller 12 controls the opening and closing of the second charging and discharging valve 32, thereby controlling the charging and discharging of the second airbag 31. When the second airbag 31 is inflated, the mold can be clamped and fixed, that is, when the mold completely enters the mold box 10, the second airbag 31 is inflated to expand it, thereby fixing the mold so that it can remain stable during operation.

[0034] As an example, a silicone rubber support pad 11 is provided at the inner bottom of the mold box 10, and a pressure sensor is embedded in the silicone rubber support pad 11, and the pressure sensor is electrically connected to the controller 12. The pressure sensor can detect whether the mold has completely entered the mold box 10. When it is detected that the mold has completely entered, the controller 12 can control the second inflation and deflation valve 32 to open, so that the second airbag 31 can be inflated and the mold can be clamped and fixed.

[0035] As an example, at least two second airbags 31 are provided, and the two second airbags 31 are arranged at intervals. The second airbag 31 and the first airbag 21 can be arranged on the same side or adjacent sides. When arranged on the same side, the second airbag 31 is located on both sides of the first airbag 21. Wherein, no matter which side is arranged, at the beginning of mold installation, the second airbag 31 is in a deflated state, and the first airbag 21 is in an inflated state; after the mold is installed, the second airbag 31 is in an inflated state, and the first airbag 21 can be in an inflated state or in a deflated state, wherein the width of the first airbag 21 and the second airbag 31 when inflated is the same.

[0036] As an example, the second airbag 31 is fixed to the inner wall of the mold box 10 through a second rubber pad 33. There is a mutual squeezing effect between the second airbag 31 and the mold. The second rubber pad 33 is arranged between the second airbag 31 and the inner wall of the box, which can play a certain protective role for the second airbag 31. The second airbag 31 is connected to a second branch pipe 34, and the second branch pipe 34 is connected to a second main pipe 35. The second branch pipe 34 and the second main pipe 35 are both located in the inner cavity of the side wall of the mold box 10; wherein, the second main pipe 35 passes through the side wall of the mold box 10 and is externally connected to a second charging and discharging interface 36, and the second charging and discharging valve 32 is connected to the second main pipe 35. The second inflation and deflation interface 36 can be a three-way interface, through which an inflation device and a deflation pipe are externally connected; when inflating, the second inflation and deflation valve 32 is opened by the controller 12, and the inflation device can inflate multiple second airbags 31 at the same time through the second main pipe 35 and the second branch pipe 34; when deflation, the second inflation and deflation valve 32 is opened by the controller 12, and multiple second airbags 31 can be deflated at the same time, so that they can be inflated and deflated quickly.

[0037] In the embodiment of the present application, an elastic protection mechanism 40 is provided on the peripheral side of the outer wall of the mold box 10, and the elastic protection mechanism 40 is used to provide anti-collision protection against external collision.

[0038] As an example, the elastic protection mechanism 40 includes an anti-collision plate 41, a mounting plate 42 and a fixing plate 43. Two fixing plates 43 are provided. The two fixing plates 43 are arranged opposite to each other and are detachably connected to the outer wall of the mold box 10. Specifically, the fixing plates 43 can be fixed by bolts to facilitate disassembly and assembly. The elastic protection mechanism 40 can be removed and installed on any outer wall of the mold that needs to be anti-collision. The mounting plate 42 is located between the two fixing plates 43 and is connected to the fixing plate 43 by a slide bar 44. The anti-collision plate 41 is located on the side of the mounting plate 42 away from the mold box 10, and a shock absorbing spring 45 is connected between the mounting plate 42 and the anti-collision plate 41. The area of ​​the anti-collision plate 41 is larger than that of the mounting plate 42, and it plays a protective role on a larger area of ​​the outer wall of the mold box 10. The shock absorbing spring 45 can play a shock absorbing and buffering role against the impact. A buffer plate 46 is connected between the anti-collision plate 41 and the slide bar 44, one end of the buffer plate 46 is hinged to the side wall of the anti-collision plate 41, and the other end of the buffer plate 46 is hinged to a slider 47, and the slider 47 is slidably connected to the slide bar 44. When a foreign object hits the anti-collision plate 41, the shock absorbing spring 45 is compressed, and the anti-collision plate 41 is pressed toward one side of the mounting plate 42. At this time, the buffer plates 46 on both sides slide to both sides on the slide bar 44, so that the anti-collision mechanism plays an effective buffering role against the impact.

[0039] As an example, at least two groups of the shock absorbing springs 45 are provided, and the two groups of the shock absorbing springs 45 are arranged in parallel to improve the buffering performance.

[0040] As an example, at least two groups of the elastic protection mechanisms 40 are provided on one side of the mold box 10. The two groups of the elastic protection mechanisms 40 are arranged in parallel and spaced apart. The two groups of the elastic protection mechanisms 40 can improve the impact stability of the mechanism.
