Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and in particular to a demolding auxiliary mechanism for injection blow molding machines. Background Technology

[0002] The demolding auxiliary mechanism of an injection blow molding machine is a mechanical or pneumatic mechanism that assists the product in smoothly leaving the mold during the demolding stage and prevents deformation.

[0003] The existing ejection mechanism of injection blow molding machines uses a simple and crude ejection method, which can easily lead to product damage and hygiene problems; it lacks an effective cooling function, which affects product quality and production efficiency; and the clamping mechanism is poorly designed, which can easily cause secondary damage.

[0004] Existing ejection mechanisms in injection blow molding machines often employ a ejection method that pushes the product out of the bottle mouth, which can easily lead to product damage, uncontrollable drop trajectories, and hygiene hazards such as internal wall contamination. Secondly, they lack the ability to cool high-temperature products instantly, resulting in uneven wall thickness and deformation due to uneven cooling, or bottle mouth defects caused by adhesion to the mold. Finally, the clamping mechanism has a simple design, with hard clamps directly contacting the product surface, which can easily cause scratches and indentations, affecting the product's appearance quality.

[0026] 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.

[0027] Example 1

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a demolding auxiliary mechanism for an injection blow molding machine includes a cylinder slide rail structure 1, a cylinder clamping structure 2 connected to the top of the cylinder slide rail structure 1, a limiting slide rail structure 3 provided on one side of the cylinder clamping structure 2, a cooling clamp 4 connected to one side of the limiting slide rail structure 3, a U-shaped flexible hose 5 provided on the outside of the cooling clamp 4, and the inside of the cooling clamp 4 connected to one end of the U-shaped flexible hose 5; the cylinder slide rail structure 1 includes a cylinder 11, a slide rail 13 fixedly connected to one side of the cylinder 11, a slider 12 slidably connected to the slide rail 13, and the top end of the slider 12 fixedly connected to the bottom end of the cylinder clamping structure 2;

[0029] One end of the output shaft of cylinder 21 is fixedly connected to a fixed groove 23. A clamp 22 is provided inside the fixed groove 23. A fixed post 24 is provided at one end of the clamp 22. The fixed groove 23 is slidably connected to the clamp 22 through the fixed post 24. A connecting frame 25 is fixedly connected to the outside of cylinder 21. The connecting frame 25 is fixedly connected to the slider 12. A limit ring 43 is fixedly connected to the end of clamp 22 away from the fixed groove 23. A connecting post 42 is slidably connected inside the limit ring 43. A clamp 2 41 is fixedly connected to both ends of the connecting post 42. The limit slide rail structure 3 includes a V-shaped slide rail 31. The limit structure 32 is fixedly connected to both ends of the V-shaped slide rail 31. A slider 2 44 is fixedly connected to the upper and lower ends of the clamp 2 41 near cylinder 21. The slider 2 44 is slidably connected to the V-shaped slide rail 31. The connecting frame 25 is fixedly connected to the V-shaped slide rail 31.

[0030] In this embodiment, the cooling clamp 4 connected to the cylinder clamping structure 2 achieves a clamping effect through the cylinder clamping structure 2. When the second cylinder 21 is started, the output shaft of the second cylinder 21 moves, which in turn moves the fixing groove 23 connected to the second cylinder 21, and then moves the clamp 22 connected to the fixing groove 23 through the fixing column 24, which in turn moves the limiting ring 43 fixedly connected to the clamp 22, and then moves the connecting column 42 slidably connected to the limiting ring 43, and finally moves the connecting column 42. The movement of the fixed clamp 41 also causes the slider 44 connected to the clamp 41 to move. The connecting column 42 and the limiting ring 43 are slidably connected to reduce friction. The connecting frame 25 fixes the cylinder 21 and the V-shaped slide rail 31. The V-shaped slide rail 31 keeps the slider 44 in a horizontal position during movement. The limiting structure 32 clamps and limits the slider 44, and finally clamps and limits the clamp 41 that is fixedly connected to the slider 44.

[0031] The cylinder slide rail structure 1 enables the cylinder clamping structure 2 connected to the cylinder slide rail structure 1 to reciprocate in the horizontal direction. When the cylinder 11 is started, the slider 12 reciprocates on the slide rail 13, thereby causing the cylinder clamping structure 2 connected to the slider 12 to reciprocate on the slide rail 13.

[0032] Example 2

[0033] like Figures 1-6 As shown, the cooling clamp 4 includes a second clamp 41. A cooling hose 45 is fixedly connected to the groove of the second clamp 41. The top end of the cooling hose 45 is connected to a pump connection pipe 46 and a connecting pipe 47. A U-shaped hose 48 is provided on one side of the connecting pipe 47. One end of the pump connection pipe 46 is connected to the connecting pipe 47 through the U-shaped hose 48. The outer side of the cooling hose 45 is connected to one end of the second U-shaped hose 45.

[0034] In this embodiment, a pump inlet pipe 46 is connected to an external pump, and coolant is pumped into the inlet pipe 46. This fills the cooling hose 45 connected to the inlet pipe 46 with coolant, and also fills the U-shaped hose 48 connected to the inlet pipe 46 with coolant. Furthermore, the connecting pipe 47 connected to the U-shaped hose 48 is filled with coolant, and finally the cooling hose 45 connected to the connecting pipe 47 is filled with coolant, achieving the cooling effect in a single cooling clamp 4. Coolant is then introduced into the cooling hose 45 connected to the other end of the U-shaped hose 45 through the second U-shaped hose 5, thereby achieving the cooling effect in multiple cooling clamps 4. The cooling hose 45 moves with the movement of the clamp 41. The length of the U-shaped hose 45 is greater than the farthest distance between adjacent clamps 41 when the clamp 41 is clamped. The length of the U-shaped hose 48 is greater than the farthest distance between clamps 41 when the clamp 41 is open.

[0035] Working principle:

[0036] like Figures 1-6 As shown, when cylinder 21 is started, the output shaft of cylinder 21 moves, which in turn causes the fixed groove 23 connected to cylinder 21 to move, which in turn causes the clamp 22 connected to the fixed groove 23 via the fixed column 24 to move, which in turn causes the limiting ring 43 fixedly connected to clamp 22 to move, which in turn causes the connecting column 42 slidably connected to the limiting ring 43 to move, which in turn causes the clamp 41 fixedly connected to the connecting column 42 to move, and also causes the slider 44 connected to clamp 41 to move, ultimately achieving the clamping effect;

[0037] The sliding connection between the connecting column 42 and the limiting ring 43 reduces friction. The connecting frame 25 fixes the cylinder 21 and the V-shaped slide rail 31. The V-shaped slide rail 31 keeps the slider 44 in a horizontal position when it moves. The limiting structure 32 clamps and limits the slider 44, and finally clamps and limits the fixture 41 that is fixedly connected to the slider 44.

[0038] The cooling hose 45 moves with the movement of the clamp 41. It is connected to an external pump through the pump connection pipe 46, which pumps coolant into the pump connection pipe 46. This fills the cooling hose 45 connected to the pump connection pipe 46 with coolant, and also fills the U-shaped hose 48 connected to the pump connection pipe 46 with coolant. This further fills the connecting pipe 47 connected to the U-shaped hose 48 with coolant, and finally fills the cooling hose 45 connected to the connecting pipe 47 with coolant, achieving the cooling effect in a single cooling clamp 4. The coolant is then introduced into the cooling hose 45 connected to the other end of the U-shaped hose 45 through the U-shaped hose 45, thus achieving the cooling effect in multiple cooling clamps 4.

[0039] The cylinder slide rail structure 1 allows the cylinder clamping structure 2 connected to the cylinder slide rail structure 1 to reciprocate in the horizontal direction. When the cylinder 11 is activated, the slider 12 reciprocates on the slide rail 13, which in turn causes the cylinder clamping structure 2 connected to the slider 12 to reciprocate on the slide rail 13. This achieves the effect of clamping the second clamp 41 when it approaches the bottle and releasing it when it moves away from the injection blow molding machine, ultimately releasing the bottle into the frame.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
