Description

Technical Field

[0001] The utility model specifically relates to a universal injection nozzle structure. Background Art

The injection molding machine is provided with a feeding machine for feeding, and an injection head for feeding is arranged on the feeding machine. The existing injection head is fixed. During the feeding process, the contact surface between the injection head and the die may be uneven due to the unevenness of the die itself or assembly errors, resulting in a gap between the contact surface of the injection head and the die. During the injection molding process, the rubber material will leak out from the gap, causing waste of materials and affecting the quality of the product at the same time.

The spherical nozzle is detachably installed on the universal discharging nozzle through the locking nut. A first flow channel communicating with the universal discharging nozzle is opened on the spherical nozzle, and a second flow channel communicating with the injection head is opened on the universal discharging nozzle.

[0005] Preferably, the universal discharging nozzle includes an installation part, a locking part and a discharging part. A plurality of first limiting holes are opened on the installation part, and second limiting holes corresponding to the first limiting holes are opened on the support seat. An external thread corresponding to the internal thread of the locking nut is formed on the outer surface of the locking part, and the discharging part is spherical.

[0006] Preferably, the spherical nozzle includes a nozzle part and a semi-circular support part. The semi-circular support part abuts against the locking part, and a support ring platform is arranged at the connection between the semi-circular support part and the locking part.

[0007] Preferably, an elastic pad is arranged between the support ring platform and the locking part.

[0008] Preferably, a limiting ring with an inward reduced diameter is formed on one end face of the locking nut, and the diameter of the limiting ring is smaller than the diameter of the support ring platform.

[0009] Preferably, an elastic member is filled between the limiting ring and the support ring platform.

[0010] Compared with the prior art, the utility model has the following beneficial effects: Due to the rotatable nozzle of the universal injection nozzle structure, the plane of the spherical nozzle can closely adhere to the contact surface of the mold, enabling automatic leveling when the plane of the spherical nozzle contacts the end face of the mold, effectively reducing the occurrence of leakage problems, saving materials and improving product quality. The entire device has a simple and practical structure, and is characterized by convenient use and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the above features and advantages of the utility model more obvious and understandable, specific embodiments are hereby given and detailed descriptions are made below in conjunction with the accompanying drawings.

[0016] As Figures 1 to 3 shown, a universal injection nozzle structure includes a spherical nozzle 1, a locking nut 2, a universal discharge nozzle 3 and an injection head 4. The universal discharge nozzle 3 is detachably mounted on the injection head 4 through a support seat 5. The spherical nozzle 1 is detachably mounted on the universal discharge nozzle 3 through the locking nut 2. A first flow channel 6 communicating with the universal discharge nozzle 3 is provided on the spherical nozzle 1. A second flow channel 7 communicating with the injection head is provided on the universal discharge nozzle 3.

[0017] In this embodiment, the universal discharge nozzle 3 includes a mounting portion 8, a locking portion 9 and a discharge portion 10. A plurality of first limiting holes 11 are provided on the mounting portion 8. Second limiting holes 12 corresponding to the first limiting holes 11 are provided on the support seat 5. An external thread corresponding to the internal thread of the locking nut 2 is formed on the outer surface of the locking portion 9. The discharge portion 10 is spherical.

[0018] In this embodiment, the spherical nozzle 1 includes a nozzle portion 13 and a semi-circular support portion 14. The semi-circular support portion 14 covers the front end portion of the discharging portion 10 therein. The semi-circular support portion 14 is detachably abutted against the locking portion 9, and a support ring platform 15 is provided at the connection between the semi-circular support portion 14 and the locking portion 9.

[0019] In this embodiment, an elastic pad is provided between the support ring platform 15 and the locking portion 9. The elastic pad is made of a flexible material such as sponge, and the elastic pad is used to support the fine adjustment offset of the spherical nozzle 1.

[0020] In this embodiment, a limiting ring 16 with a reduced diameter inward is formed on one end face of the locking nut 2, and the diameter of the limiting ring 16 is smaller than the diameter of the support ring platform 15.
