Description

Technical Field

[0001] This invention relates to a handling device for mold positioning columns. Background Technology

[0002] Positioning pins are components used in injection molds to precisely lock the position between the module and the template, ensuring accurate alignment and stable operation of the mold during work. The function of positioning pins is similar to that of guide components, mainly serving as guides and positions, helping the moving mold and fixed mold to be precisely aligned when closed, thus ensuring the quality of the molded product. The processing of positioning pins requires multiple steps, and the positioning pins need to be transported to the processing equipment before processing.

[0003] With the continuous development of automation technology, most positioning columns now have automatic conveying functions. However, the existing positioning column conveying mechanisms are laid horizontally and are quite long, which means they can only be used in processing areas with large spaces. If the processing area is small, they cannot fully accommodate the entire conveying mechanism. At the same time, various equipment and facilities in the processing area are intertwined, and the horizontally laid conveying mechanism cannot perfectly avoid them. Therefore, the scope of application is limited and needs to be resolved. Summary of the Invention

[0018] like Figures 1-3 As shown, a mold positioning column conveying device includes a horizontally arranged main frame plate 1 and a material conveying mechanism 4 disposed on the main frame plate 1. The material conveying mechanism 4 includes a first rodless cylinder 41 and a first V-shaped material support plate 42. The first rodless cylinder 41 is horizontally fixed to the top of the main frame plate 1. The opening of the first V-shaped material support plate 42 is arranged facing upward.

A guide slope 461 is formed at the right corner of the top of the seat block 46.

It also includes two side frame plates 2 that are vertically fixed on the left and right sides of the bottom of the main frame plate 1, a feeding mechanism 3 on the right side frame plate 2, and a discharging mechanism 5 on the left side frame plate 2.

The feeding mechanism 3 includes a second rodless cylinder 31, a first Z-shaped bracket 32, and a second V-shaped material support plate 33. The second rodless cylinder 31 is longitudinally fixed to the outside of the side frame plate 2. The first Z-shaped bracket 32 ​​is longitudinally fixed to the moving end of the second rodless cylinder 31 so that it has the function of vertical movement up and down with the help of the second rodless cylinder 31. The bottom corner of the second V-shaped material support plate 33 is rotatably elastically connected to the end of the first Z-shaped bracket 32 ​​so that it always has the tendency to rotate counterclockwise. The feeding mechanism 3 also includes a U-shaped guide bar 34 that is vertically fixed to the outside of the side frame plate 2 and parallel to the movement direction of the moving end of the second rodless cylinder 31, a second fork 35 that is horizontally fixed to the left outer wall of the second V-shaped material support plate 33, and a guide pulley 36 that is rotatably connected to the end of the second fork 35. The opening side of the U-shaped guide bar 34 is set facing the second V-shaped material support plate 33, and the guide pulley 36 is rolled and embedded inside the U-shaped guide bar 34.

[0019] The upper end of the U-shaped guide bar 34 extends above the main frame plate 1.

A guide arc surface 371 is formed on the upper corner of the transition block 37 facing the guide notch 341.

[0020] A conversion mechanism 6 is also provided between the material conveying mechanism 4 and the feeding mechanism 3. The conversion mechanism 6 includes two side plates 61 fixed on the top of the main frame plate 1 and symmetrically located on the front and rear sides of the right end of the first rodless cylinder 41, and a first guide trough plate 62 inclinedly fixed between the two side plates 61. The first guide trough plate 62 is set with the right side higher than the left side, and the right edge of the bottom surface of the first guide trough plate 62 is higher than the right edge of the opening of the first V-shaped material support plate 42.

[0021] The conversion mechanism 6 also includes a first portal frame 63 that is vertically fixed to the top of the main frame plate 1 and located above the right end of the first rodless cylinder 41, a material blocking cylinder 64 fixed on the first portal frame 63, and a material blocking plate 64 that is vertically fixed to the telescopic end of the material blocking cylinder 64 and movably disposed inside the first guide trough plate 62. The telescopic end of the material blocking cylinder 64 is arranged laterally to the right.

[0022] The feeding mechanism 5 includes a third rodless cylinder 51 longitudinally fixed to the outside of the side frame plate 2, a second Z-shaped bracket 52 longitudinally fixed to the moving end of the third rodless cylinder 51 to enable vertical movement with the help of the third rodless cylinder 51, a third V-shaped material support plate 53 fixed to the end of the second Z-shaped bracket 52, a second portal bracket 54 laterally fixed to the outside of the side frame plate 2, and a second guide trough plate 55 inclinedly fixed to the second portal bracket 54. The opening of the third V-shaped material support plate 53 is set upwards, and the second guide trough plate 55 is set with the right side higher than the left side. The bottom right edge of the second guide trough plate 55 is provided with a receiving groove 551 that cooperates with the third V-shaped material support plate 53. The front and rear width of the receiving groove 551 is not less than the front and rear length of the third V-shaped material support plate 53.

[0023] A correction mechanism 7 is also provided between the feeding mechanism 5 and the conveying mechanism 4. The correction mechanism 7 includes a first correction plate 71 and a second correction plate 72 that are vertically fixed on the top of the main frame plate 1 and located on the front and rear sides of the left end of the first rodless cylinder 41, respectively. The distance between the left end of the first correction plate 71 and the left end of the second correction plate 72 is less than the distance between the right end of the first correction plate 71 and the right end of the second correction plate 72.

[0024] The correction mechanism 7 also includes two uprights 73 fixed to the top of the main frame plate 1 and located to the left of the first rodless cylinder 41 and arranged symmetrically in front and behind, and two limiting plates 74 respectively vertically fixed on the two uprights 73 and arranged symmetrically in front and behind and inclined. Each limiting plate 74 is arranged with the right side higher than the left side. The distance between the inner walls of the two limiting plates 74 is not less than the front and rear lengths of the first V-shaped material support plate 42 and the third V-shaped material support plate 53.

[0025] The correction mechanism 7 also includes a fall arrestor plate 75 that is vertically fixed to the top of the main frame plate 1 and located to the left of the two limit plates 74.

[0026] The material conveying mechanism 4 also includes a third fork 47 that is inclined and fixed on the outer right side of the first V-shaped material support plate 42, and a limiting pulley 48 that is longitudinally and rotatably connected to the end of the third fork 47 and cooperates with the moving end of the first rodless cylinder 41.

[0027] Working principle: The moving end of the second rodless cylinder 31 in the feeding mechanism 3 moves downward to the bottom, thereby driving the second V-shaped support plate 33 to move synchronously with the help of the first Z-shaped bracket 32. During this process, the guide pulley 36 rolls vertically downward along the U-shaped guide strip 34 inside, thus ensuring that the opening of the second V-shaped support plate 33 always faces upward and remains unchanged. The positioning pin 8 is placed horizontally in the second V-shaped support plate 33 and the moving end of the second rodless cylinder 31 is driven upward to the bottom, thereby driving the positioning pin 8 to move synchronously with the help of the second V-shaped support plate 33 until the second V-shaped support plate 33 is in position. Located above the right of the first guide trough plate 62 in the conversion mechanism 6; when the guide pulley 36 rolls to the guide notch 341 on the U-shaped guide bar 34, the counterclockwise rotational rebound force of the second V-shaped support plate 33 will force the guide pulley 36 to come out from the guide notch 341 and swing towards the transition block 37 until the guide pulley 36 rolls and fits against the guide arc surface 371. At this time, the angle of the second V-shaped support plate 33 changes, and its opening turns to the left so that the positioning post 8 rolls into the first guide trough plate 62, and then continues to roll to the left along the slope of the first guide trough plate 62.

[0028] Before this, the moving end of the first rodless cylinder 41 in the material conveying mechanism 4 needs to be driven to move to the right to the end, thereby driving the first V-shaped material support plate 42 to move synchronously. During this process, the support pulley 45 rolls to the right along the top outer wall of the guide beam 43 until the right edge of the opening of the first V-shaped material support plate 42 is located below the left end of the first guide trough plate 62, thereby causing the positioning post 8 rolling along the first guide trough plate 62 to roll into the first V-shaped material support plate 42. Then, the telescopic end of the blocking cylinder 64 in the conversion mechanism 6 is driven to extend outward to drive the blocking plate 64 to move to the right into the interior of the first guide trough plate 62, thus preventing the positioning post 8 that subsequently enters the first guide trough plate 62 from continuing to roll.

[0029] Next, the moving end of the first rodless cylinder 41 is driven to move to the left, so as to drive the first V-shaped material support plate 42 and the positioning column 8 to move synchronously. When the support pulley 45 leaves the left end of the guide beam 43, it will roll onto the guide inclined surface 461 on the seat block 46. Since the first V-shaped material support plate 42 always has the tendency to rotate counterclockwise to reset, the angle of the first V-shaped material support plate 42 also changes so that its opening also turns to the left. During this process, the first V-shaped material support plate 42 enters between the first alignment plate 71 and the second alignment plate 72 in the correction mechanism 7. When the two ends of the positioning column 8 contact the inner walls of the first alignment plate 71 and the second alignment plate 72 respectively, the positioning column 8 will move forward or backward to correct its position.

[0030] Before this, the moving end of the third rodless cylinder 51 in the feeding mechanism 5 needs to be driven upward to the bottom so that the third V-shaped support plate 53 can be moved synchronously with the help of the second Z-shaped bracket 52 until the right edge of the opening of the third V-shaped support plate 53 is between the two limiting plates 74 and lower than the left edge of the opening of the first V-shaped support plate 42. This will allow the positioning post 8 in the first V-shaped support plate 42 to roll to the left into the third V-shaped support plate 53. During this process, the two ends of the positioning post 8 slide through the inner walls of the two limiting plates 74 to ensure that the front and rear positions of the positioning post 8 remain unchanged. The anti-fall plate 75 can prevent the positioning post 8 from rolling away from the third V-shaped support plate 53 due to excessive inertia.

[0031] Finally, the moving end of the third rodless cylinder 51 is driven to move downwards to the bottom, so that the third V-shaped material support plate 53 and the positioning column 8 can also move downwards in the same way. Since the length of the positioning column 8 is greater than the front and rear width of the receiving groove 551 on the second guide plate 55, when the third V-shaped material support plate 53 passes downwards through the receiving groove 551, the positioning column 8 will be intercepted by the receiving groove 551 in the second guide plate 55, and then roll to the left along the slope of the second guide plate 55 to output, thus completing the automatic material discharge.

[0032] When the first V-shaped support plate 42 needs to transport the next positioning column 8 again, the moving end of the first rodless cylinder 41 needs to be driven to move to the right to move synchronously with the first V-shaped support plate 42. This causes the support pulley 45 to gradually leave the guide slope 461 and roll onto the top outer wall of the guide beam 43, so that the opening of the first V-shaped support plate 42 gradually returns to the correct position until it is facing upward. During this process, the limiting pulley 48 swings downward with the first V-shaped support plate 42 until it rolls and adheres to the moving end of the first rodless cylinder 41.

[0033] The material conveying mechanism 4 of this invention undertakes the task of straight conveying, thereby separating the loading and unloading processes and completing them respectively by the loading mechanism 3 and the unloading mechanism 5. This shortens the length of the straight conveying, making it suitable for processing areas with limited space. At the same time, the conveying direction of both the loading mechanism 3 and the unloading mechanism 5 is changed to longitudinal, which makes full use of the vertical space in the processing area. The material conveying mechanism 4 is suspended above the loading mechanism 3 and the unloading mechanism 5. Even if various equipment and facilities in the processing area are intertwined, the material conveying mechanism 4 can perfectly avoid them by virtue of its height advantage, thus breaking through the limitations of the scope of application and making it suitable for large-scale promotion.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
