Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine with a bottle embryo uniform cooling structure. Background Art

[0002] A lotion bottle is a specially designed bottle, which is mainly used to store lotion products, such as face cream, lotion, essence and other cosmetics. Common lotion bottles are made of PET plastic material, and injection molding machines are used in the production process of lotion bottles. Existing injection molding machines still have certain defects when used.

[0003] In the prior art, lotion bottle injection molding machines are important equipment for producing lotion bottles. After the plastic is heated, the molten plastic will be injected into the mold, and after cooling and solidification, it will form the shape of the lotion bottle. Since the bottle embryo is formed quickly during the processing, the temperature of the surface of the bottle embryo after forming is high, and it is difficult to cool down evenly and effectively, making it difficult to use the formed bottle embryo in time. Utility Model Content

[0004] The utility model aims to provide an injection molding machine with a uniform cooling structure for bottle preforms, so as to solve the problem that the injection molding machines currently on the market are difficult to uniformly cool the bottle preforms as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molding machine with a uniform cooling structure for bottle embryos, comprising: an injection molding machine main body, a blanking hole, a mold box, a movable mold, a heating box and a hopper, the inside of the injection molding machine main body is provided with a blanking hole, the top of the injection molding machine main body is provided with a mold box near the blanking hole, the inside of the mold box is provided with a movable mold, the top of the injection molding machine main body is provided with a heating box away from the mold box, the top of the heating box is provided with a hopper, a baffle plate is provided inside the injection molding machine main body near the blanking hole, a mounting block is welded inside the injection molding machine main body, the top of the mounting block is threadedly connected with a threaded knob, a cooling fan is provided at the bottom of the mounting block, a T-shaped block is connected to the top of the cooling fan, a slide seat is welded to the inner wall of the injection molding machine main body, a collection box is provided between the two slide seats, guide plates are connected to both sides of the collection box, and a heat-resistant rubber pad is bonded to the inside of the collection box.

[0006] Preferably, a slide groove matching the size of the guide plate is provided inside the slide seat, and a sliding structure is formed between the guide plate and the slide seat.

[0007] Preferably, two groups of heat dissipation fans are symmetrically arranged about the center of the blanking hole.

[0008] Preferably, a bearing seat is installed on the top of the heating box, and a screw rod is connected between two bearing seats.

[0009] Preferably, the end of the screw rod is connected to a rotating ring, and the outer side of the screw rod is threadedly connected to a sliding block.

[0010] Preferably, an inclined plate is connected to the end of the slider, a sealing rubber block is connected to the outer side of the hopper close to the slider, and a spring telescopic inclined block is installed inside the hopper.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the injection molding machine with a uniform cooling structure for preforms can drive the T-shaped block to move when the cooling fan moves, and when the T-shaped block slides to the inside of the mounting block, the threaded knob can be tightened so that the end of the threaded knob can be threadedly fixed with the T-shaped block, and a small amount of material inside the hopper can fall into the heating box, so that the bottom end of the hopper is not easily blocked, and the falling amount of the material inside the hopper can adjust the position of the inclined plate, and at the same time the sealing rubber block can improve the sealing of the hopper, so that the material inside the hopper is not easy to leak out.

[0012] 1. The lotion bottle injection molding machine is widely used in the cosmetics, personal care, medicine and other industries. Since the lotion bottle is formed quickly, and the formed bottle blank is difficult to cool down quickly, the bottle blank is difficult to use in time. When the cooling fan moves, it can drive the T-shaped block to move. When the T-shaped block slides to the inside of the mounting block, the threaded knob can be tightened so that the end of the threaded knob can be threadedly fixed with the T-shaped block, thereby fixing the position of the cooling fan. After the bottle blank is formed, it falls from the mold box through the drop hole to the inside of the collection box. After the bottle blank falls into the collection box, it will contact the heat-resistant rubber pad. At the same time, the baffle plate can limit the falling bottle blank, so that the bottle blank is not easy to fall to the outside of the collection box. The bottle blank is located When the bottles are collected in a box, two sets of cooling fans can blow air to dissipate heat to the preforms in the box, thereby achieving a cooling effect. The staff can pull the box back and forth. When the box moves, it can drive the guide plate to move. When the guide plate moves, it can slide with the slide seat. When the box moves back and forth, it can drive the preforms in the box to move. At this time, the cooling fans can evenly dissipate heat and cool the preforms, so that the surface temperature of the preforms after forming can be quickly dissipated and cooled, and the preforms can be used in time. When the preforms in one set of boxes are cooled, they can be taken out and another set of boxes can be used to receive the materials. The two sets of boxes can be used alternately.

[0013] 2. The lotion bottle injection molding machine can quickly make plastic into bottle blanks. Due to the narrow diameter of the bottom end of the hopper, once there is a lot of material inside the hopper, it is easy to cause blockage at the bottom end of the hopper, which can easily affect the production efficiency of the injection molding machine. When the rotating ring rotates, it can drive the screw to rotate forward. When the screw rotates, it can drive the slider to slide in the direction of the hopper. When the inclined plate moves to the specified position, the inclined plate can partially block the material inside the hopper, and a small amount of material inside the hopper can fall into the heating box, so that the bottom end of the hopper is not easy to be blocked, and the falling amount of the material inside the hopper can adjust the position of the inclined plate. At the same time, the sealing rubber block can improve the sealing of the hopper, so that the material inside the hopper is not easy to leak out. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 5It can be seen that the utility model provides a technical solution: an injection molding machine with a uniform cooling structure for bottle embryos, comprising: an injection molding machine body 1, a blanking hole 2, a mold box 3, a movable mold 4, a heating box 5 and a hopper 6. The injection molding machine body 1 is provided with a blanking hole 2, the injection molding machine body 1 is provided with a mold box 3 installed on the top near the blanking hole 2, the movable mold 4 is installed inside the mold box 3, the injection molding machine body 1 is provided with a heating box 5 on the top away from the mold box 3, the hopper 6 is installed on the top of the heating box 5, a baffle plate 7 is installed inside the injection molding machine body 1 near the blanking hole 2, and the internal welding of the injection molding machine body 1 is provided. A mounting block 8 is connected, the top of the mounting block 8 is threadedly connected to a threaded knob 9, a cooling fan 10 is arranged at the bottom of the mounting block 8, the top of the cooling fan 10 is connected to a T-shaped block 11, a slide seat 12 is welded to the inner wall of the injection molding machine body 1, a collecting box 13 is arranged between the two slide seats 12, guide plates 14 are connected to both sides of the collecting box 13, a heat-resistant rubber pad 15 is bonded to the inside of the collecting box 13, a slide groove matching the size of the guide plate 14 is opened inside the slide seat 12, a sliding structure is formed between the guide plate 14 and the slide seat 12, and two groups of cooling fans 10 are symmetrically arranged about the center of the blanking hole 2.

[0022] In specific implementation, the lotion bottle injection molding machine is widely used in the cosmetics, personal care, medicine and other industries. Since the lotion bottle is formed quickly, but the formed bottle blank is difficult to cool down quickly, it is difficult to use the bottle blank in time. The cooling fan 10 can be pushed first. When the cooling fan 10 moves, the T-shaped block 11 can be driven to move. When the T-shaped block 11 slides into the inside of the mounting block 8, the threaded knob 9 can be tightened so that the end of the threaded knob 9 can be threadedly fixed with the T-shaped block 11, thereby fixing the position of the cooling fan 10. When the injection molding machine is in use, two sets of cooling fans 10 can be started. When the bottle blank is formed, it passes through the blanking hole 2 The preforms fall from the mold box 3 to the collection box 13. After falling into the collection box 13, they will contact the heat-resistant rubber pad 15. The heat-resistant rubber pad 15 can reduce the force of the falling collision of the preforms, thereby reducing the deformation of the preforms due to the collision. At the same time, the falling preforms can be restricted by the baffle plate 7, so that the preforms are not easy to fall to the outside of the collection box 13. When the preforms are located in the collection box 13, the two sets of cooling fans 10 can blow air to the preforms in the collection box 13 to dissipate heat, thereby achieving a cooling effect. The staff can pull the collection box 13 back and forth. When the collection box 13 moves, it can drive the guide plate 14 to move.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 5It can be seen that when the guide plate 14 moves, it can slide with the slide seat 12. When the collection box 13 moves back and forth, it can drive the bottle blanks inside the collection box 13 to move. At this time, the cooling fan 10 can evenly dissipate heat and cool the bottle blanks, so that the surface temperature of the formed bottle blanks can be quickly dissipated and cooled, and the bottle blanks can be used in time. When the bottle blanks inside a group of collection boxes 13 are cooled, they can be taken out and another group of collection boxes 13 can be used to receive the materials. The two groups of collection boxes 13 can be used alternately back and forth.

[0024] See also Figure 1 and Figure 4 It can be seen that a bearing seat 16 is installed on the top of the heating box 5, a screw rod 17 is connected between the two bearing seats 16, a rotating ring 18 is connected to the end of the screw rod 17, a slider 19 is threadedly connected to the outer side of the screw rod 17, an inclined plate 20 is connected to the end of the slider 19, a sealing rubber block 21 is connected to the outer side of the hopper 6 near the slider 19, a spring telescopic inclined block 22 is installed inside the hopper 6, and the shape of the slider 19 is L-shaped.

[0025] During specific implementation, the lotion bottle injection molding machine can quickly make plastic into bottle blanks. Since the diameter of the bottom end of the hopper 6 is narrow, once there is a lot of material inside the hopper 6, it is easy to cause the bottom end of the hopper 6 to be blocked, which is easy to affect the production efficiency of the injection molding machine. The rotating ring 18 can be rotated forward. When the rotating ring 18 rotates, it can drive the screw rod 17 to rotate forward. When the screw rod 17 rotates, it can drive the slider 19 to slide in the direction of the hopper 6. When the slider 19 slides, it can drive the inclined plate 20 to move. When the inclined plate 20 moves to the specified position, the inclined plate 20 can partially block the material inside the hopper 6, and when the inclined plate 20 is moving, the bottom end of the spring telescopic inclined block 22 will always be pressed on the surface of the inclined plate 20, thereby preventing material leakage.

[0026] See also Figure 1 and Figure 4 It can be seen that a small amount of material inside the hopper 6 can fall into the heating box 5, so that the bottom end of the hopper 6 is not easily blocked, and the falling amount of the material inside the hopper 6 can adjust the position of the inclined plate 20. At the same time, the sealing rubber block 21 can improve the sealing of the hopper 6, so that the material inside the hopper 6 is not easy to leak out.

[0027] In summary, when the injection molding machine with the uniform cooling structure for preforms is used, the heating box 5 can heat the plastic in the hopper 6 into a molten state, and the molten plastic can be processed into a preform for a lotion bottle through the movable mold 4 and the static mold. Various cosmetics can be stored in the preforms. The collecting box 13 can drive the preforms in the collecting box 13 to move in position during the process of moving back and forth. At this time, the cooling fan 10 can evenly dissipate heat and cool the preforms, so that the surface temperature of the preforms after molding can quickly dissipate heat and cool, and the preforms can be used in time. After the preforms in one set of collecting boxes 13 are cooled, they can be taken out and another set of collecting boxes 13 can be used to receive the materials. The two sets of collecting boxes 13 can be used alternately back and forth. The materials in the hopper 6 can fall into the heating box 5 in small amounts, so that the bottom of the hopper 6 is not easily blocked, and the falling amount of the materials in the hopper 6 can adjust the position of the inclined plate 20. At the same time, the sealing rubber block 21 can improve the sealing of the hopper 6, so that the materials in the hopper 6 are not easy to leak out.
