Description

Technical Field

[0001] This application relates to the field of injection molding machines, and more specifically, to an injection molding machine with an easy-to-change nozzle. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. The injection molding operation is performed through injection nozzles.

[0003] Most injection molding machines require nozzle replacement during use. Existing injection molding machine nozzles are installed using threads, which is inefficient for disassembly and assembly. Furthermore, the extrusion pressure acting on the nozzle can easily cause thread failure, stripping, and loosening. Utility Model Content

[0004] To overcome the above deficiencies, this application provides an injection molding machine with an easy-to-change nozzle, which aims to improve the problems mentioned in the background art.

[0005] This application provides an injection molding machine with an easy-to-change nozzle, including an injection molding assembly and a nozzle assembly.

[0006] The injection molding assembly includes a support base and an injection molding machine body, with the injection molding machine body positioned on top of the support base.

[0007] The nozzle assembly includes a connector, an elastic element, a limiting plate, a fixed toothed plate, an injection nozzle, and a toothed plate. The connector is located at the end of the injection molding machine body. The elastic element is disposed on the outside of the connector. The limiting plate is fixedly connected to the elastic element. The fixed toothed plate is fixedly connected to the connector. The toothed plate is fixedly connected to the injection nozzle. The injection nozzle is inserted into the connector. The toothed plate and the fixed toothed plate mesh with each other.

[0008] In one specific implementation, the elastic element includes a spring and a sliding ring, the spring being sleeved on the connector, the sliding ring being slidably sleeved on the connector, and the limiting plate being fixedly connected to the sliding ring.

[0009] In the above implementation process, by setting a spring and a sliding ring, the elastic extension and contraction of the spring can drive the sliding ring and the limiting plate to move, and keep them inserted between the two fixed toothed plates without the action of external force.

[0010] In one specific implementation, the fixed toothed plate is L-shaped, and the sliding ring abuts against one end of the fixed toothed plate.

[0011] In the above implementation process, an L-shaped fixed toothed plate is set, and the arc-shaped toothed groove on the inner wall can engage with the rack plate, which is also used to limit the sliding of the sliding ring.

[0012] In one specific implementation, the rack plate is arc-shaped, the rack plate is adapted to the inner wall of the fixed toothed groove plate, and the rack plate abuts against the limiting plate.

[0013] In the above implementation process, by setting an arc-shaped rack plate, the rotating rack plate can be made to mesh into the fixed toothed groove plate. Then, the limiting plate is pushed between the two fixed toothed groove plates by the spring and the sliding ring, thereby restricting the rotation of the rack plate and ensuring stable connection.

[0014] In one specific implementation, the inner end of the injection nozzle is tapered, and the inner wall of the connector is tapered, with the injection nozzle fitting against the inner wall of the connector.

[0015] In the above process, by setting the conical injection nozzle and the conical connector inner wall to fit together, the contact area can be increased and the sealing performance can be improved.

[0016] In one specific implementation, a retaining ring is fixedly connected to the outer side of the injection nozzle, and the rack plate is fixedly connected to the retaining ring.

[0017] In the above implementation process, a fixing ring is set to support the rack plate and the injection nozzle, so that it fits onto the injection nozzle.

[0018] In one specific implementation, the outer side of the fixing ring is provided with anti-slip texture.

[0019] In the above implementation process, anti-slip texture is set to improve friction and prevent slippage when disassembling and assembling the injection nozzle.

[0020] In one specific implementation, a feeding hopper is connected to the top of the injection molding machine body, and a cover plate is provided on the top of the feeding hopper.

[0021] In the above implementation process, a feeding hopper is set up to add raw materials into the main body of the injection molding machine.

[0022] Beneficial effects: This application provides an injection molding machine that facilitates nozzle replacement. By setting up a support base, injection molding machine body, connector, elastic element, limiting plate, fixed toothed plate, injection nozzle, and toothed plate, the injection nozzle is easily disassembled and assembled by using the meshing connection between the toothed plate and the fixed toothed plate. Furthermore, the rotation of the toothed plate is restricted by the cooperation of the elastic element and the limiting plate, thereby ensuring the stability and sealing of the injection nozzle connection. Disassembly is also more convenient and quick, improving the efficiency of disassembly and replacement. Attached Figure Description

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Please see Figures 1-5 This application provides an injection molding machine with an easy-to-change nozzle, including an injection molding assembly 100 and a nozzle assembly 200.

[0032] Please see Figure 1 and 2 The injection molding assembly 100 includes a support base 110 and an injection molding machine body 120, with the injection molding machine body 120 located on top of the support base 110.

[0033] The injection molding machine body 120 is connected to a feeding hopper 121 at the top, and the feeding hopper 121 is covered with a cover plate. The feeding hopper 121 is used to add raw materials into the injection molding machine body 120.

[0034] Please see Figure 1 , 2 3, 4, and 5, the nozzle assembly 200 includes a connector 210, an elastic element 220, a limiting plate 230, a fixed toothed plate 240, an injection nozzle 250, and a rack plate 260. The connector 210 is located at the end of the injection molding machine body 120. The elastic element 220 is disposed on the outside of the connector 210. The limiting plate 230 is fixedly connected to the elastic element 220. The fixed toothed plate 240 is fixedly connected to the connector 210. The rack plate 260 is fixedly connected to the injection nozzle 250. The injection nozzle 250 is inserted into the connector 210. The rack plate 260 and the fixed toothed plate 240 mesh with each other.

[0035] The elastic element 220 includes a spring 221 and a sliding ring 222. The spring 221 is sleeved on the connector 210, and the sliding ring 222 is slidably sleeved on the connector 210. The limiting plate 230 is fixedly connected to the sliding ring 222. By setting the spring 221 and the sliding ring 222, the elastic extension and contraction of the spring 221 can drive the sliding ring 222 and the limiting plate 230 to move, and keep them inserted between the two fixed toothed plates 240 without the action of external force.

[0036] Specifically, the fixed toothed plate 240 is L-shaped, and the sliding ring 222 abuts against one end of the fixed toothed plate 240. By setting the L-shaped fixed toothed plate 240, the arc-shaped toothed groove on the inner wall can engage the rack plate 260, which also restricts the sliding of the sliding ring 222.

[0037] In this embodiment, the rack plate 260 is arc-shaped and is adapted to the inner wall of the fixed toothed plate 240. The rack plate 260 abuts against the limiting plate 230. By setting the arc-shaped rack plate 260, the rotating rack plate 260 can be engaged into the fixed toothed plate 240. Then, the limiting plate 230 is pushed between the two fixed toothed plates 240 by the spring 221 and the sliding ring 222, thereby restricting the rotation of the rack plate 260 and ensuring stable connection.

[0038] It should be noted that the inner end of the injection nozzle 250 is conical, and the inner wall of the connector 210 is also conical. The injection nozzle 250 fits against the inner wall of the connector 210. By setting the conical injection nozzle 250 and the conical inner wall of the connector 210 to fit together, the contact area can be increased and the sealing performance can be improved.

[0039] In one specific implementation, a fixing ring 251 is fixedly connected to the outside of the injection nozzle 250, and a rack plate 260 is fixedly connected to the fixing ring 251. The fixing ring 251 is used to support the rack plate 260 and the injection nozzle 250, so that it fits onto the injection nozzle 250.

[0040] In one specific implementation, the outer side of the retaining ring 251 is provided with anti-slip texture. By providing anti-slip texture, it is convenient to increase friction and avoid slipping when disassembling and assembling the injection nozzle 250.

[0041] The working principle of this easy-to-replace injection molding machine is as follows: During disassembly, pulling the sliding ring 222 compresses the spring 221. The sliding ring 222 moves the limiting plate 230, moving its outer end past the end of the rack plate 260. This allows the fixing ring 251 to rotate, causing the injection nozzle 250 to rotate. Simultaneously, the arc-shaped rack plate 260 rotates, allowing the rack plate 260 to rotate out of the fixed toothed plate 240, thus removing the injection nozzle 250. During installation, the injection nozzle 250 can be directly inserted into the connector 210. The rack plate 260 abuts against and pushes the limiting plate 230, which in turn pushes the sliding ring 221. 22. Squeeze the spring 221, then rotate the fixing ring 251. The fixing ring 251 drives the injection nozzle 250 to rotate, engaging the arc-shaped rack plate 260 into the fixing toothed groove plate 240. When properly aligned, the spring 221 elastically returns to its original position, pushing the sliding ring 222 and the limiting plate 230. The limiting plate 230 enters between the two fixing toothed groove plates 240, thereby restricting and blocking the rotation of the rack plate 260. The inner walls of the conical injection nozzle 250 and the conical connector 210 fit together, increasing the contact area and ensuring the stability and sealing of the injection nozzle 250 connection. Disassembly is also more convenient and quick, improving the efficiency of disassembly and replacement.

[0042] It should be noted that the specific model and specifications of the injection molding machine body 120 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0043] The power supply and its principle for the injection molding machine body 120 are clear to those skilled in the art and will not be described in detail here.

[0044] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
