When the pressure reaches a preset threshold, it means that the left fixed mold and the right movable mold are tightly combined without a gap, and the green indicator light comes on. When the pressure is lower than the preset threshold, it means that the left fixed mold and the right movable mold are not tightly combined and there is a gap, and the red indicator light comes on, reminding the staff to carry out timely maintenance, thereby realizing the function of mold closing sealing feedback.

DETAILED DESCRIPTION

[0025] 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.

[0026] Example 1: Please refer to Figure 1-5 A high-precision medical straw blow molding mold for easy demoulding includes a first fixed plate 1 and a second fixed plate 17. A fixed mold mounting plate 2 is fixedly connected to one side of the first fixed plate 1. A left fixed mold 3 is fixedly connected to one side of the fixed mold mounting plate 2. Five groups of fixed mold grooves 4 are arranged on one side of the left fixed mold 3. Four groups of sliding rods 14 are transversely fixedly connected between the fixed mold mounting plate 2 and one side of the second fixed plate 17. A bottom mounting plate 8 is transversely fixedly connected to the bottom of the other side of the first fixed plate 1 and the second fixed plate 17. A movable mold mounting plate 15 is arranged on the left side of the second fixed plate 17. The sliding rod sleeves 16 are fixedly connected to the inside of the four corners of the movable mold mounting plate 15, and the right movable mold 19 is fixedly connected to the other side of the movable mold mounting plate 15. Five groups of movable mold grooves 20 are arranged inside one side of the right movable mold 19. Four groups of mounting screw eyes 9 are arranged at the front and rear ends of the bottom of the bottom mounting plate 8, and the front and rear ends of the top of the bottom mounting plate 8 are welded with support plates 13. A hydraulic cylinder 18 is installed between one side of the second fixed plate 17 and one side of the movable mold mounting plate 15. A demoulding component is arranged on the other side of the first fixed plate 1 to facilitate the removal of the material inside the fixed mold groove 4.

[0027] See also Figure 1-5 A high-precision medical straw blow molding mold for easy demoulding also includes a demoulding component, which includes a cylinder 5, which is installed at the middle position of the other side of the first fixed plate 1, and a push plate 6 is arranged inside the middle position of one side of the left fixed mold 3;

[0028] One side of the cylinder 5 is connected to one side of the push plate 6, and one side of the push plate 6 is flush with one side of the left fixed die 3. Five groups of plate die grooves 7 are arranged inside one side of the push plate 6. The position and size of the plate die grooves 7 correspond to the position and size of the fixed die groove 4 one by one, so that the material can be pushed out to make it fall off and avoid the material from sticking to the die;

[0029] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the cylinder 5 extends outward and pushes the push plate 6 to move to the right. The push plate 6 pushes out the material attached to the inside of the fixed die groove 4, causing it to fall off naturally. The material plate die groove 7 and the fixed die groove 4 have the same shape and do not affect the normal forming of the straw.

[0030] Embodiment 2: Two groups of load sensors 10 are installed on the top of the bottom mounting plate 8, a buzzer 11 is installed at the middle position of the top of the bottom mounting plate 8, and the bottom end of the load sensor 10 is movably connected with a sensor contact 12, which passes through the bottom end of the bottom mounting plate 8 and extends to the outside. The sensor contact 12 can move up and down along the inside of the bottom mounting plate 8, and can intuitively feedback the stability of the connection between the mold and the base;

[0031] Specifically, Figure 1 and Figure 4 As shown, as the bolts are tightened, the sensor contacts 12 at the bottom of the load sensor 10 are also pressed against the top of the base. As long as the bolts are not loose, the overall pressure value is constant. When the pressure value sensed by the load sensor 10 shows a significant decrease or a fluctuating trend, it means that the bolts are loose, and the buzzer 11 sounds to remind the staff to check.

[0032] Embodiment 3: Multiple groups of positioning guide rods 21 are fixedly connected to the front and rear ends of one side of the right movable mold 19, and multiple groups of guide rod grooves 22 are respectively arranged inside the front and rear ends of one side of the left fixed mold 3. A pressure sensor 23 is installed on one side of the guide rod groove 22. A red indicator light 24 is installed on the top of the front end of the left fixed mold 3, and a green indicator light 25 is installed on the bottom of the front end of the left fixed mold 3. The positions of the positioning guide rods 21 and the guide rod grooves 22 correspond to each other. The pressure sensor 23, the red indicator light 24, and the green indicator light 25 are electrically connected, which can provide feedback on whether the mold connection is tight or not;

[0033] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, the positioning guide rod 21 on the side of the right movable mold 19 will be directly inserted into the guide rod groove 22 on the side of the left fixed mold 3, and the positioning guide rod 21 will press against the pressure sensor 23 in the guide rod groove 22. When the pressure reaches the preset threshold, it means that the left fixed mold 3 and the right movable mold 19 are tightly combined without gaps, and the green indicator light 25 lights up. When the pressure is lower than the preset threshold, it means that the left fixed mold 3 and the right movable mold 19 are not tightly combined and there are gaps, and the red indicator light 24 lights up to remind the staff to repair in time.

[0034] Working principle: When the utility model is in use, first, the bottom mounting plate 8 is docked with the top of the base, and the feeding mechanism is suspended above the left fixed mold 3. As the feeding mechanism lowers the blank, the hydraulic cylinder 18 pushes the movable mold mounting plate 15 to move laterally along the sliding rod 14, and the left fixed mold 3 and the right movable mold 19 are closed, and the fixed mold groove 4 and the movable mold groove 20 clamp the blank therebetween. Under the blowing of the feeding mechanism, the heat-softened blank continues to expand and fit the fixed mold groove 4 and the movable mold groove 20, and is shaped into a straw after cooling. After cooling, the hydraulic cylinder 18 retracts to separate the left fixed mold 3 and the right movable mold 19, and the cylinder 5 extends outward to push the push plate 6 to move to the right. The push plate 6 pushes out the material attached to the inside of the fixed mold groove 4, causing it to fall off naturally. The material plate mold groove 7 and the fixed mold groove 4 are consistent in shape, and do not affect the normal forming of the straw. The bottom mounting plate 8 is butted against the top of the base, and the bolts are driven in from the mounting screw eyes 9. As the bolts are tightened, the sensor contacts 12 at the bottom of the load sensor 10 are also pressed against the top of the base. As long as the bolts are not loose, the overall pressure value is constant. When the pressure value sensed by the load sensor 10 shows a significant decrease or a fluctuating trend, it means that the bolts are loose, and the buzzer 11 sounds to remind the staff to check. When the left fixed mold 3 and the right movable mold 19 are closed, the positioning guide rod 21 on the side of the right movable mold 19 will be directly inserted into the guide rod groove 22 on the side of the left fixed mold 3, and the positioning guide rod 21 is pressed against the pressure sensor 23 in the guide rod groove 22. When the pressure reaches the preset threshold, it means that the left fixed mold 3 and the right movable mold 19 are tightly combined without gaps, and the green indicator light 25 is on. When the pressure is lower than the preset threshold, it means that the left fixed mold 3 and the right movable mold 19 are not tightly combined with gaps, and the red indicator light 24 is on to remind the staff to repair in time.
