Detailed Implementation

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0026] The technical solution of this utility model will be described in detail below with specific embodiments.

[0027] refer to Figure 1-5 As shown, this utility model discloses a safety mold removal platform based on the mold area of ​​an injection molding machine, including a machine base 1. The machine base 1 is provided with a fixed template 2 and a movable template 3. A first pull rod 4 and a second pull rod 5 are passed between the fixed template 2 and the movable template 3. A safety platform 6 is provided between the first pull rod 4 and the second pull rod 5. One end of the safety platform 6 covers the first pull rod 4, and the other end of the safety platform 6 covers the second pull rod 5. The fixed template 2 is fixed to one end of the machine base 1, and the movable template 3 can move on the first pull rod 4 and the second pull rod 5.

[0028] Specifically, such as Figure 2As shown, the first pull rod 4 and the second pull rod 5 have smooth parts at both ends and threaded parts in the middle. After the injection molding is completed, the moving platen 3 separates from the fixed platen 2 along the first pull rod 4 and the second pull rod 5 until the moving platen 3 moves to the threaded parts of the first pull rod 4 and the second pull rod 5. At this time, the distance between the fixed platen 2 and the moving platen 3 is a safe distance, which is called the safe area on the machine base 1. The safe area is equipped with multiple safety pedals 12. During the process of the operator entering the safe area to pick up the injection-molded product, a safety platform 6 is set before the operator enters the safe area. The operator can enter the safe area through the safety platform 6, which effectively avoids the operator having to step over the pull rods from the front pedal to enter the safe area due to the large size of the first pull rod 4 and the second pull rod 5 and the high distance between them and the machine base 1. This reduces the risk of safety accidents and effectively protects the personal safety of the operator. Preferably, the safety platform 6 is made of metal material, which is composed of steel or aluminum alloy. Steel has high strength, can withstand the impact of frequent trampling, and has low manufacturing cost; while aluminum alloy has lightweight characteristics, which can significantly reduce the weight of the safety platform 6 and reduce the load on the first pull rod 4 and the second pull rod 5.

[0029] In this embodiment, as Figure 3 As shown, the safety platform 6 includes: a frame 60, a first pedal 61 on the frame 60, a first support rod 62 on both sides of the first pedal 61, and a second pedal 63 on the side of the first support rod 62 away from the first pedal 61.

[0030] A step group 64 is provided on one side of the first support rod 62 near the first pedal 61, and a second support rod 631 is provided on the other side of the second pedal 63 connected to the first support rod 62, so that the second support rod 631 and the step group 64 are respectively arranged opposite to each other on both sides of the second pedal 63. The second support rod 631 is provided at the bottom of the second pedal 63 in the direction close to the step group 64, and a third pedal 65 is provided on the second support rod 631 in the direction away from the first pedal 61.

[0031] Specifically, considering the placement and movement of the injection molding machine, the safety platform 6 only needs to have a stepped structure on one side to facilitate the operator's entry into the safety pedal 12 to complete the mold removal work, which also saves manufacturing costs; there is a height difference between the first pedal 61 and the safety pedal 12, that is, the first pedal 61 and the safety pedal 12 do not contact each other, so as to prevent the upper surface of the safety pedal 12 from being scratched when the safety platform 6 is in use, and the height difference between the first pedal 61 and the safety pedal 12 is not large, which is sufficient for the operator to safely step on the safety pedal 12; the second pedal 63 is an L-shaped plate, the vertical part of the L-shaped plate is connected to the outside of the first support rod 61, the horizontal part of the L-shaped plate is the part for the operator to step on, and there is a mounting block 66 on the horizontal part of the L-shaped plate to facilitate the subsequent locking of the entire safety platform 6 onto the first pull rod 4 and the second pull rod 5. The bottom of the horizontal part of the L-shaped plate is provided with a second support rod 631.

[0032] In this embodiment, the bottom of the step group 64 is abutted by the first pedal 61, and the top of the step group 64 is connected to the top of the first support rod 62.

[0033] Specifically, the outer side of the bottom of the step assembly 64 abuts against the first pedal 61, meaning there is no gap between the step assembly 64 and the first pedal 61. This ensures that when the operator steps onto the last step of the step assembly 64, they can safely step onto the first pedal 61, preventing the operator from getting their feet stuck. The step assembly 64 is detachably connected to the frame 60, and the top of the step assembly 64 is also detachably connected to the top of the second support rod 631, facilitating subsequent replacement and maintenance of the step assembly 64.

[0034] In this embodiment, as Figure 4 As shown, the second pedal 63 has a mounting block 66 at its bottom, and the mounting block 66 has a bearing sleeve 67 at its bottom.

[0035] Priority, such as Figure 1 As shown, the safety platform 6 is engaged with the smooth portions of the first pull rod 4 and the second pull rod 5 via a bearing sleeve 67. The safety platform 6 can slide axially on the first pull rod 4 and the second pull rod 5 by moving the bearing sleeve 67. Preferably, two mounting blocks 66 are provided on both sides of the bottom of the second pedal 63 to avoid the need to replace the entire mounting block 66 due to damage to a single mounting block 66, effectively reducing production costs. The two mounting blocks 66 also ensure even force distribution on the second pedal 63, allowing the operator to step on it more stably and reducing the possibility of the safety platform 6 tipping over. Preferably, the bearing sleeve 67 is designed in a semi-circular arc shape, which better matches the first pull rod 4 and the second pull rod 5, increasing the tightness of the connection between the safety platform 6 and the first pull rod 4 and the second pull rod 5, and reducing frictional wear caused by the bearing sleeve 67's contact with the first pull rod 4 and the second pull rod 5.

[0036] In this embodiment, as Figure 4 and Figure 5 As shown, the bearing sleeve 67 is provided with bearing sleeve retaining edges 68 on both sides.

[0037] Specifically, the bearing sleeve retaining edge 68 is used to strengthen the fixation of the bearing sleeve 67 and prevent the bearing sleeve 67 from loosening and falling off due to prolonged sliding on the first pull rod 4 and the second pull rod 5.

[0038] In this embodiment, as Figure 4 As shown, an oil nozzle 7 is provided on the bearing sleeve 67 in a direction away from the first pedal 61, and an oil groove 8 is provided at the bottom of the bearing sleeve 67 that communicates with the oil nozzle 7.

[0039] Specifically, lubricating oil enters the oil groove 8 through the grease nipple 7, forming an oil film between the first pull rod 4 and the second pull rod 5 and the bearing sleeve 67. This reduces the friction between the bearing sleeve and the first pull rod 4 and the second pull rod 5, prevents the safety platform 6 from directly contacting the first pull rod 4 and the second pull rod 5, and reduces the risk of friction and wear of the first pull rod 4 and the second pull rod 5 during the movement of the safety platform 6.

[0040] In this embodiment, as Figure 4 As shown, the bottom of the second pedal 63 is provided with a reinforcing member 9.

[0041] Specifically, the reinforcing member 9 is located at the corner of the bottom of the second pedal 63 to enhance the rigidity and strength of the overall structure of the second pedal 63, reduce the possibility of the second pedal 63 breaking or bending when subjected to weight, and prevent the operator from stepping into the void when entering the full pedal area 12, thus effectively ensuring the operator's personal safety.

[0042] In this embodiment, as Figure 1 As shown, a mold-moving assembly 10 is provided on one side of the fixed template 2 and the moving template 3, and a protective assembly 11 is provided on the other side of the fixed template 2 and the moving template 3.

[0043] Preferred, the mold transfer assembly 10 uses hydraulic transmission to drive the moving platen 3 to move; the protective assembly 11 includes: a protective base 111 connected to the base 1, a head plate front frame 112 set along the direction close to the fixed platen 2 on the protective base 111, and a protective door 113 that cooperates with the head plate front frame 112; the protective base 111 is provided with a front step 114. Before entering the safety platform 6, the operator should stand in the front step 114 to ensure that his body is stable before entering the safety platform 6, so as to avoid the operator from stepping into a hole or tripping; during the operation of the injection molding machine, the protective door 113 abuts against the head plate front frame 112 to prevent personnel from entering the front step 114, avoid operator injury, and ensure the operator's personal safety.

[0044] In this embodiment, the first pull rod 4 is disposed in the direction close to the mold moving assembly 10, the second pull rod 5 is disposed in the direction close to the protective assembly 11, the second pedal 63 with the third pedal 65 is mounted on the second pull rod 5, and another second pedal 63 is disposed on the first pull rod 4.

[0045] Specifically, such as Figure 1 As shown, a mold-moving assembly 10 is provided on one side of the first pull rod 4. The distance between the two is relatively large, which makes it inconvenient for the operator to enter the safety platform 6. A front pedal 114 is provided on one side of the second pull rod 5. The front pedal 114 is a prerequisite for the operator to enter the safety platform 6 more smoothly. Therefore, installing the second pedal 63, which is provided with the third pedal 65, on the second pull rod 5 is a prerequisite for ensuring the operator's safe mold removal.

[0046] In this embodiment, the second support rod 631 is provided with a plurality of third pedals 65 in a stepped manner from top to bottom.

[0047] Specifically, the above-mentioned configuration is designed to prevent the span between the third pedal 65 and the second pedal 63 from being too large, and the distance between the third pedal 65 and the front pedal 114 from being too large, so as to avoid the operator from stepping into a hole or tripping when entering the safety platform, and to fully protect the operator's personal safety.

[0048] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
