Description

Technical Field

[0001] The utility model relates to the field of injection devices, and particularly to an injection device of an injection molding machine. Background Art

[0002] As is well known, an injection molding machine is a main molding device that forms various shaped plastic products from thermoplastic or thermosetting plastics through a plastic molding die. The principle of the injection molding machine is to add molten raw materials into the internal material bin of the injection molding machine, and then send them into the injection head through the thrust of a screw. Subsequently, it enters the mold cavity inside the mold. Then, the injection device can inject the molten plastic into the closed mold cavity. After the molten raw material is formed into a solid state, a product identical to the mold cavity can be obtained.

[0003] However, most of the existing injection devices of injection molding machines on the market at present cannot arbitrarily adjust the injection angle, which greatly reduces the applicability of the device and thus greatly reduces the practicality of the device. Content of the Utility Model

[0007] To achieve the purpose of being able to arbitrarily adjust the injection angle and improving the applicability of the device, the utility model provides the following technical solution: An injection device of an injection molding machine includes an injection head and a mounting block. An adjustment channel is opened at the bottom of the mounting block, the inner wall of the adjustment channel is an inclined plane, a adjustment block is fixedly connected to the top of the injection head, a groove is opened on the outer wall of the adjustment block, and a second spring is fixedly connected to the inner wall of the groove.

[0008] One end of the second spring is fixedly connected with a limiting block. A clamping block is fixedly connected to the inner wall of the adjusting channel. An adjusting groove is formed at the bottom of the clamping block, and a clamping groove is formed in the inner wall of the adjusting groove. A fixing ring is fixedly connected to the outer wall of the injection head, and a discharge nozzle is fixedly connected to the bottom of the injection head. By providing the injection head, the adjusting block, the limiting block, the clamping groove and the discharge nozzle, the angle of the injection head is directly adjusted through the discharge nozzle of the injection head, and the angle of the discharge nozzle is adjusted according to the angle required for injection molding. Since the number of the limiting blocks and the clamping grooves is multiple, after the angle of the injection head is adjusted, the multiple limiting blocks will be clamped with their respective corresponding clamping grooves, thereby realizing the fixation of the injection head again, and further realizing that the device can arbitrarily adjust the injection molding angle, thereby greatly improving the applicability of the device and the practicality of the device.

By providing the bolt, the installation block can be installed at the required position on the injection molding machine frame.

[0010] As a preferred technical solution of the present invention, a conveying pipe is fixedly connected to the outer wall of the injection head, and the conveying pipe is fixedly sleeved with the installation block.

[0016] Beneficial effects:

[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings of the specification.

[0025] Embodiment 1

[0026] Refer to Figures 1-4, which is the first embodiment of the present utility model, provides an injection device for an injection molding machine, including an injection head 1 and a mounting block 3. An adjustment channel 6 is provided at the bottom of the mounting block 3, and the inner wall of the adjustment channel 6 is an inclined surface. One end of the injection head 1 is located inside the adjustment channel 6, thereby expanding the range of the adjustment angle of the injection head 1. A regulating block 9 is fixedly connected to the top of the injection head 1, a groove 10 is provided on the outer wall of the regulating block 9, and a second spring 11 is fixedly connected to the inner wall of the groove 10.

[0027] One end of the second spring 11 is fixedly connected with a limiting block 12. When a force acts on the surface of the limiting block 12, it will move into the groove 10. The second spring 11 has a large elastic force, so that the limiting block 12 will not automatically move into the groove 10. A clamping block 13 is fixedly connected to the inner wall of the adjustment channel 6. An adjustment groove 16 is provided at the bottom of the clamping block 13, and a clamping groove 14 is provided on the inner wall of the adjustment groove 16. A fixing ring 7 is fixedly connected to the outer wall of the injection head 1, and a discharge nozzle 15 is fixedly connected to the bottom of the injection head 1. The bottom of the injection head 1 is outside the mounting block 3. Therefore, when the angle of the injection head 1 needs to be adjusted, the angle of the injection head 1 can be directly changed by the discharge nozzle 15 of the injection head 1.

[0028] A mounting plate 5 is fixedly connected to the outer wall of the mounting block 3, and a bolt 4 is rotatably sleeved on the top of the mounting plate 5. Therefore, the mounting block 3 can be installed at the required position on the injection molding machine frame through the bolt 4.

[0029] A delivery pipe 2 is fixedly connected to the outer wall of the injection head 1, and the delivery pipe 2 is fixedly sleeved with the mounting block 3. The delivery pipe 2 is connected to an external delivery mechanism. Therefore, the molten raw material can be delivered into the injection head 1 through the delivery pipe 2.

[0030] The shape of the limiting block 12 is a "sphere" structure, and the shape of the clamping block 13 is a "semicircle" structure. The outer wall of the regulating block 9 is slidably connected to the inner wall of the adjustment groove 16. When the bottom of the injection head 1 is rotated, the regulating block 9 can rotate inside the adjustment groove 16 under the action of a force, thereby realizing the change of the angle of the discharge nozzle 15.

[0031] The shape of the clamping groove 14 is adapted to the limiting block 12, and the limiting block 12 is movably clamped with the clamping groove 14. Through the clamping of the limiting block 12 and the clamping groove 14, the clamping of the regulating block 9 and the adjustment groove 16 is realized. Therefore, the regulating block 9 will not rotate inside the adjustment groove 16 without the action of a force. Therefore, the injection head 1 will not automatically change the angle of the discharge nozzle 15 without being adjusted by others.

[0032] The outer wall of the fixed ring 7 is fixedly connected to a first spring 8, and one end of the first spring 8 is fixedly connected to the inner wall of the adjustment channel 6. The elastic force of the first spring 8 is less than the elastic force of the second spring 11. Thus, when changing the angle of the injection head 1, the first spring 8 assists in applying a force to the injection head 1, making it more convenient to change the angle of the injection head 1.

[0033] During use, the mounting block 3 is installed at the required position on the injection molding machine frame through the bolt 4. When it is necessary to adjust the angle of the injection head 1, directly adjust the angle of the injection head 1 through the discharge nozzle 15 of the injection head 1. When the injection head 1 receives a force, it will drive the adjustment block 9 to rotate. When the surface of the limit block 12 receives a force, it will move into the groove 10, thereby adjusting the angle of the discharge nozzle 15 according to the required angle of injection molding. The number of the limit blocks 12 and the card slots 14 is multiple. After the angle of the injection head 1 is adjusted, the multiple limit blocks 12 will be engaged with their respective corresponding card slots 14, thereby realizing the fixation of the injection head 1 again.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
