Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine equipment, in particular to a rapid demoulding structure of an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is a main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It has vertical, horizontal, and all-electric types. It mainly heats the plastic and applies high pressure to the molten plastic to make it ejected and fill the mold cavity. After cooling and solidification, a molded product is obtained.

[0003] Based on the above, after the existing injection molding machines complete the injection molding process, most of them are manually demolded by operators, which is extremely inconvenient. In addition, since the injection molding has just been completed, the molded parts in the injection molding machine mold will adhere to the injection mold groove, which greatly increases the workload of the operators who manually demold.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] (1) The utility model discloses a rapid demoulding structure of an injection molding machine, which drives two connected left and right groups of rotating wheels to rotate together through the rotation of a dual-axis motor. The rotation of the rotating wheels drives the eccentric column to make an eccentric movement, thereby driving the connecting rod and the sliding rod to move back and forth. Under the limiting action of the limiting groove, the sliding rod can only move back and forth, thereby driving the striking cylinder to repeatedly strike the injection molding upper mold, and can vibrate and demould the injection molded parts in the injection molding upper mold, thereby improving the demoulding effect of the injection molding machine.

[0017] (2) The utility model provides a rapid demoulding structure of an injection molding machine. When the U-shaped seat is reciprocating, it will drive the long rod connected to it to reciprocate together, thereby driving the piston rod to move together, and generating gas by performing an inflating movement in the cylinder. The generated gas will be discharged from the air outlet pipe to the injection molding upper mold, and blown into the injection molding groove through the connecting hole, thereby blowing out the molded parts in the injection molding groove. By cooperating with the vibration mechanism, the molded parts can be quickly demoulded after being injected, thereby increasing the demoulding effect and efficiency.

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] Embodiment 1:

[0027] See also Figure 1-Figure 4 A quick demoulding structure of an injection molding machine includes an injection molding machine 1, a feeding mechanism 2, a heating mechanism 3, an injection mold 4, a mold opening mechanism 5 and a vibration mechanism 6. The feeding mechanism 2 is installed on the top of the injection molding machine 1. One side of the feeding mechanism 2 is connected to the heating mechanism 3 that can heat and melt the plastic. The injection end of the heating mechanism 3 is connected to the injection mold 4. Two sets of vibration mechanisms 6 are installed on one side of the injection mold 4. The other side of the injection mold 4 is movably matched with the mold opening mechanism 5.

[0028] In this embodiment, the vibration mechanism 6 includes a base plate 61, a driving member 62 and a striking member 63. One side of the base plate 61 is connected to the injection mold 4. The driving member 62 is installed on the base plate 61. The driving member 62 is rotatably matched with the striking member 63 which can vibrate and strike the injection molded part in the injection mold 4.

[0029] In this embodiment, the driving member 62 includes a dual-axis motor 11, a rotating wheel 12, an eccentric column 13, a fixed block 14 and a limiting groove 15. The dual-axis motor 11 is located on the base plate 61. The output ends on both sides of the dual-axis motor 11 are connected to the rotating wheels 12 that can be driven to rotate by the dual-axis motor 11. The rotating wheel 12 is connected to the eccentric column 13, and the eccentric column 13 is connected to the striking member 63. One side of the two rotating wheels 12 is provided with a fixed block 14 connected to the base plate 61, and a limiting groove 15 is provided on the fixed block 14. The dual-axis motor 11 is electrically connected to the electrical control box in the injection molding machine 1.

[0030] In this embodiment, the striking member 63 includes a connecting rod 21, a U-shaped seat 22, a sliding rod 23 and a striking tube 24. The connecting rod 21 is connected to the eccentric column 13, and the end of the connecting rod 21 away from the eccentric column 13 is connected to the U-shaped seat 22. A sliding rod 23 is fixed inside the U-shaped seat 22. The sliding rod 23 is located in the limiting groove 15 and slides with the limiting groove 15. The limiting groove 15 limits the movement of the sliding rod 23. A striking tube 24 is fixed to one end of the sliding rod 23, and the striking tube 24 is made of soft rubber.

[0031] Working principle:

[0032] First: after the injection molding machine 1 completes the injection molding work, the mold opening mechanism 5 is driven to drive the static mold of the injection molding to separate;

[0033] Second: the dual-axis motor 11 is driven by the electric control box. As the dual-axis motor 11 rotates, the two sets of left and right rotating wheels 12 connected thereto will rotate together. When the rotating wheels 12 rotate, the eccentric column 13 will be driven to rotate and perform eccentric motion. Since the eccentric column 13 is connected to the connecting rod 21, the connecting rod 21 and the sliding rod 23 will be driven to move back and forth. Under the limiting effect of the limiting groove 15, the sliding rod 23 will only move back and forth, thereby driving the striking cylinder 24 to repeatedly strike the injection mold 4, and the injection molded parts in the injection mold 4 can be vibrated and demolded.

[0036] In this embodiment, the other end of the air outlet pipe 34 is communicated with the injection groove on the injection upper mold 4 .

[0037] Working principle: When the U-shaped seat 22 moves back and forth driven by the rotating wheel 12 and the connecting rod 21, it will drive the long rod 31 connected to the two U-shaped seats 22 to move back and forth together. As the long rod 31 moves, the piston rod 32 connected to it will move together, so that it can perform an inflating movement in the cylinder 33 to generate gas, and then the generated gas will be discharged from the outlet pipe 34, and then the gas will be blown into the injection molding groove through the connecting hole on the injection molding upper mold 4, blowing out the injection molded parts in the injection molding groove, and by cooperating with the vibration mechanism 6, the injection molded parts can be quickly demolded.
