Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production technology, and in particular to an injection molding machine for steel wire mesh composite pipe fittings. 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.

[0003] A search revealed a PVC pipe fitting injection molding machine (publication number: CN222223310U), comprising a support plate, a transmission cylinder connected to the top of the support plate, and a transmission power assembly connected to the inner left end of the transmission cylinder; an installation plate located at the outer right end of the transmission cylinder, with an extrusion connection assembly at the right end of the installation plate, which is easily detachable and heated for easy cleaning; and a feed hopper located at the top of the transmission cylinder, with an installation plate connected to the top of the feed hopper, and a stirring and heating assembly installed inside the installation plate, which can improve the melting effect while stirring and prevent solidification and blockage during the transmission process.

[0004] In the prior art, after the particles are melted, they are conveyed to the mold by a conveyor. The connecting bridge between the conveyor and the mold is a nozzle. However, the nozzle in the prior art is a hollow funnel structure. When the material flows through the nozzle, it can only have a radial flow effect, which has high resistance and is easy to form seams. If the material is injected into the mold in a tangential rotation manner, the flow resistance can be reduced and the formation of seams can be reduced. Therefore, the nozzle in the prior art has room for optimization.

[0005] Therefore, we propose an injection molding machine for steel wire mesh composite pipe fittings. Utility Model Content

[0006] The present invention mainly addresses the technical problems of high resistance and easy formation of joint marks when materials flow through the nozzle, and provides a steel wire mesh composite pipe injection molding machine.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a steel wire mesh composite pipe injection molding machine, comprising:

[0008] A base, on the top of which a conveyor is fixedly installed, and above the conveyor a hopper for feeding materials is fixedly installed;

[0009] A nozzle assembly is detachably mounted at the end of the conveyor for material discharge. The nozzle assembly includes an outer cylinder, a flow guide body, and cutting guide vanes. The outer cylinder is detachably connected to the conveyor. The flow guide body is installed inside the outer cylinder. Several cutting guide vanes are fixedly arranged inside the flow guide body. The cutting guide vanes form a spiral injection channel on the inner wall of the flow guide body.

[0010] In a preferred embodiment of this utility model, the outer cylinder is funnel-shaped, and flanges are fixedly installed at both ends of the outer cylinder. The flanges are locked and fixed to the conveyor by bolts.

[0011] In a preferred embodiment of this utility model, the flow guiding body forms a cylindrical tube with a constricted opening, both ends of the flow guiding body are open, the outer wall of the flow guiding body is attached to the inner wall of the outer cylinder, and the flow guiding body and the outer cylinder are used in cooperation with each other.

[0012] In a preferred embodiment of this utility model, the cutting guide plate is formed into a spiral plate, the cutting guide plate is fixedly connected to the inner wall of the guide body, and multiple cutting guide plates are distributed in a ring array on the inner wall of the guide body.

[0013] In a preferred embodiment of the present invention, the nozzle assembly further includes a baffle, which is fixedly installed with the flow guide body, and the outer cylinder can press the baffle tightly against the end of the conveyor.

[0014] In a preferred embodiment of this utility model, the baffle is integrally formed with the flow guide body, and the baffle is located at the larger port of the flow guide body.

[0015] In a preferred embodiment of this utility model, the flange at the end of the outer cylinder is provided with a groove, the groove being an annular groove, the retaining edge cooperating with the groove, the thickness of the retaining edge being equal to the depth of the groove, and the end of the retaining edge being flush with the flange end face when embedded in the groove.

[0016] Beneficial effects

[0017] This utility model provides an injection molding machine for steel wire mesh composite pipe fittings. It has the following beneficial effects:

[0018] 1. This steel wire mesh composite pipe injection molding machine features a detachable flow guide body installed inside the outer cylinder. Multiple cutting guide vanes are equidistantly arranged on the inner wall of the flow guide body. When flowing material enters the flow guide body, it forms a vortex injection channel through the multiple spiral cutting guide vanes, allowing molten polyethylene material to be injected into the mold in a tangential rotational manner. This reduces flow resistance and eliminates weld lines. Simultaneously, the material is sheared and squeezed as it passes through the flow guide body, promoting material mixing.

[0019] 2. This type of steel wire mesh composite pipe injection molding machine uses bolts to lock the flange to the conveyor. When disassembling, the bolts are loosened, the flange is removed, and the guide body can be pulled out. The flange falls off from the groove, making it easy to clean the guide body and avoid residual material scaling and clogging. It is also convenient for replacement and maintenance. There are several guide bodies, and the pitch of the cutting guide plates in each guide body can be distributed in a gradient. They can be replaced and matched according to the different fluidity of the material in the molten state to ensure the pushing effect on the material. Attached Figure Description

[0026] A steel wire mesh composite pipe injection molding machine, such as Figure 1 and Figure 2 As shown, it includes:

[0027] A base 10 is provided, and a conveyor 11 is fixedly installed on the top of the base 10. A hopper 12 for feeding materials is fixedly installed above the conveyor 11. In this solution, the conveyor 11 is equipped with an auger, which is driven by a motor to push materials. The conveyor 11 is equipped with an electric heating rod for melting granular materials. The molten slurry is transported to the extrusion molding die through the conveyor 11 to form a pipe. Since this is a mature existing technology, it will not be described in detail here.

[0028] like Figure 2 and Figure 3 As shown, the nozzle assembly is detachably installed at the end of the conveyor 11 for material discharge. The nozzle assembly includes an outer cylinder 20, a flow guide body 30, and cutting guide plates 31. The outer cylinder 20 is detachably connected to the conveyor 11. The flow guide body 30 is installed inside the outer cylinder 20. Several cutting guide plates 31 are fixedly installed inside the flow guide body 30. The cutting guide plates 31 form a spiral injection channel on the inner wall of the flow guide body 30. The outer cylinder 20 is funnel-shaped. Flanges 21 are fixedly installed at both ends of the outer cylinder 20. The flanges 21 are locked to the conveyor 11 by bolts. The flow guide body 30 forms a constricted cylinder. Both ends of the flow guide body 30 are open. The outer wall of the flow guide body 30 is attached to the inner wall of the outer cylinder 20. The flow guide body 30 and the outer cylinder 20 cooperate with each other. The cutting guide plates 31 form a spiral plate. The cutting guide plates 31 are fixedly connected to the inner wall of the flow guide body 30. Multiple cutting guide plates 31 are distributed in a ring array on the inner wall of the flow guide body 30.

[0029] In this design, a detachable flow guide body 30 is installed inside the outer cylinder 20. Multiple cutting guide vanes 31 are equidistantly arranged on the inner wall of the flow guide body 30. When the flowing material enters the flow guide body 30, a vortex injection channel is formed by the multiple spiral cutting guide vanes 31, which allows the molten polyethylene material to be injected into the mold in a tangential rotation manner, reducing flow resistance and eliminating weld lines. At the same time, the material can be sheared and squeezed when it passes through the flow guide body 30, promoting the mixing of the material.

[0030] like Figure 4 and Figure 5 As shown, the nozzle assembly also includes a flange 32, which is fixedly installed with the flow guide body 30. The outer cylinder 20 can press the flange 32 against the end of the conveyor 11. The flange 32 is integrally formed with the flow guide body 30. The flange 32 is located at the larger port of the flow guide body 30. The flange 21 at the end of the outer cylinder 20 has a groove 22. The groove 22 is an annular groove. The flange 32 and the groove 22 cooperate with each other. The thickness of the flange 32 is equal to the depth of the groove 22. When the flange 32 is embedded in the groove 22, its end is flush with the end face of the flange 21.

[0031] As a supplementary explanation to the above scheme, the flange 21 is locked to the conveyor 11 with bolts. When disassembling, the bolts are loosened, the flange 21 is removed, and the guide body 30 is pulled out. The retaining edge 32 falls out of the groove 22, which facilitates the cleaning of the guide body 30, avoids residual material from scaling and clogging, and facilitates replacement and maintenance. There are several guide bodies 30, and the pitch of the cutting guide blades 31 in each guide body 30 can be distributed in a gradient. They can be replaced and matched according to the different fluidity of the material in the molten state to ensure the pushing effect on the material.

[0032] The working principle of this utility model is as follows: The guide body 30 is placed inside the outer cylinder 20, the flange 32 is embedded in the groove 22, and the flange 21 is locked to the conveyor 11 with bolts to complete the installation. The conveyor 11 is equipped with an auger, which is driven by a motor to push the material. The outside of the conveyor 11 is equipped with an electric heating rod for melting granular materials. The molten slurry is transported to the extrusion molding mold through the conveyor 11 to form a pipe. The detachable guide body 30 is installed inside the outer cylinder 20, and multiple cutting guide plates 31 are equidistantly arranged on the inner wall of the guide body 30. When the flowing material enters the guide body 30, it forms a vortex injection channel through the multiple spiral cutting guide plates 31, so that the molten polyethylene material is injected into the mold in a tangential rotation manner, reducing flow resistance and eliminating weld lines, thus ensuring the quality and pass rate of the produced pipe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
