Technical Field

[0001] This invention relates to the field of injection molding equipment technology, and in particular to a rotary high-efficiency continuous injection mold equipment. 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] Traditional injection molding machines typically have only one set of molds. After injection molding, the finished product needs to be cooled and solidified by a cooling system before it can be ejected to complete the unloading process. During this process, the injection molding machine needs to wait for the ejection to be completed before closing the mold again and proceeding to the next injection process. This inability to continuously inject leads to reduced efficiency and affects production output. Summary of the Invention

[0006] Multiple injection molds are arranged horizontally side by side on the upper side of the injection molding machine body. A rotating shaft is provided on the frame of the injection molding machine body. At least a portion of the multiple injection molds can rotate around the rotating shaft as an axis.

[0007] The injection mold includes a first mold base and a second mold base, wherein a mold groove for molding molten medium is formed between the first mold base and the second mold base;

[0008] The injection piping is installed at the injection outlet of the main body of the injection molding machine, and the injection piping is used to introduce the molten medium into the corresponding mold groove.

[0009] Preferably, the second mold base includes a second mold base body, the second mold base body is fixed on the rotating shaft, and the mold groove is formed on one side surface of the second mold base body;

[0012] The extension and retraction of the drive cylinder causes the main body of the first mold base to rotate around the rotation axis via the swing rod, which can adjust the sealing state of the mold groove;

[0013] Both the first mold base body and the second mold base body have a cavity for accommodating injection molding pipelines and a clearance groove for the first mold base body to rotate around the rotation axis.

[0014] Preferably, the first mold base body has a cooling pipeline system, the cooling pipeline system includes a medium flow channel distributed in a serpentine pattern within the first mold base body, and a first medium interface and a second medium interface are respectively provided at the two openings of the medium flow channel for inputting / outputting cooling medium;

[0015] It also includes a heat dissipation copper plate embedded on the surface of the first mold base body. When the first mold base and the second mold base overlap, the heat dissipation copper plate can completely cover the mold groove.

[0016] Preferably, the injection piping includes a pipe body installed at the injection outlet of the injection molding machine body, and the pipe body is provided with a plurality of solenoid valves extending into the corresponding mold slots, and injection nozzles are installed on the solenoid valves;

[0024] Compared with the prior art, the present invention has the following beneficial technical effects:

[0025] This invention separates the first mold base body from the second mold base body by rotation, and ejects the molded part through the ejection mechanism to achieve demolding and material unloading. During this process, it does not affect the injection molding machine body and the injection pipeline supplying molten medium to other injection molds, thus solving the problem of machine stoppage and demolding during the current injection process.

[0036] Example

[0037] like Figure 1 As shown, the present invention proposes a rotary high-efficiency continuous injection molding equipment, comprising: an injection molding machine body 10, an injection mold 20, and an injection pipeline 30;

[0038] Combination Figure 2 and Figure 3 As shown, multiple injection molds 20 are arranged horizontally on the upper side of the injection molding machine body 10. A rotating shaft 24 is provided on the frame of the injection molding machine body 10. At least a portion of the multiple injection molds 20 can rotate around the rotating shaft 24 as the axis.

[0039] Specifically, the injection mold 20 includes a first mold base 21 and a second mold base 22, wherein a mold groove 222 for molding the molten medium is formed between the first mold base 21 and the second mold base 22;

[0040] The injection pipe 30 is installed at the injection outlet of the injection molding machine body 10. The injection pipe 30 is used to introduce the molten medium into the corresponding mold groove 222.

[0041] The second mold base 22 includes a second mold base body 221, which is fixed on the rotating shaft 24, and the mold groove 222 is formed on one side surface of the second mold base body 221.

[0042] When the second mold base 22 overlaps with the first mold base 21, the mold groove 222 is in a sealed state.

[0043] When the mold groove 222 is in a sealed state, the molten medium will take shape according to the shape of the mold groove 222.

[0044] The first mold base 21 includes a first mold base body 213 that can cooperate with the second mold base body 221 and can rotate about the rotation axis 24, a rocker arm 212 fixed to the end of the first mold base body 213, and a drive cylinder 211 that is hinged to the frame of the injection molding machine body 10 and whose piston rod end is hinged to the end of the rocker arm 212.

[0045] The extension and retraction of the drive cylinder 211 causes the first mold base body 213 to rotate around the rotation axis 24 via the swing rod 212, which can adjust the sealing state of the mold groove 222;

[0046] Both the first mold base body 213 and the second mold base body 221 have a cavity for accommodating the injection molding pipeline 30 and a clearance groove 224 for the first mold base body 213 to rotate around the rotation axis 24.

[0047] The drive cylinder 211 drives the rocker arm 212 and the first mold base body 213 to rotate around the rotation axis 24, thereby separating the first mold base body 213 from the second mold base body 221. During this process, the injection pipeline 30 stops adding molten medium into the mold groove 222, thus realizing the molding of the molten medium.

[0048] like Figure 3 As shown, the first mold base body 213 has a cooling pipeline system. The cooling pipeline system includes a medium flow channel 42 that is distributed in a serpentine pattern within the first mold base body 213. A first medium interface 41 and a second medium interface 43 are respectively provided at the two openings of the medium flow channel 42 for inputting / outputting cooling medium.

[0049] It also includes a heat dissipation copper plate 44 embedded on the surface of the first mold base body 213. When the first mold base 21 and the second mold base 22 overlap, the heat dissipation copper plate 44 can completely cover the mold groove 222.

[0050] The first medium interface 41 is connected to the input port of the external coolant circulation device, and the second medium interface 43 is connected to the output port of the external coolant circulation device, thereby enabling the coolant to flow in the medium flow channel 42, cooling the heat dissipation copper plate 44 through heat transfer, and achieving rapid cooling by utilizing the contact between the heat dissipation copper plate 44 and the molten medium.

[0051] The injection piping 30 includes a pipe body 33 installed at the injection outlet of the injection molding machine body 10. The pipe body 33 is provided with a plurality of solenoid valves 31 extending into the corresponding mold slots 222. An injection nozzle 32 is installed on the solenoid valve 31.

[0052] Each injection nozzle 32 is electrically connected to the corresponding drive cylinder 211;

[0053] When the drive cylinder 211 separates the first mold base 21 from the second mold base 22, the injection nozzle 32 is in a blocked state.

[0054] Specifically, the molten medium enters the solenoid valve 31 through the main pipe 33, and the solenoid valve 31 injects the molten medium into the corresponding mold groove 222. After the injection is completed, the injection nozzle 32 is in the closed state, the cooling pipeline system continuously cools the molten medium, and drives the cylinder 211 to adjust the rotation of the first mold base body 213, thereby exposing the molded finished product.

[0055] A sealing ring 223 is provided on the side surface where the second mold base body 221 joins the first mold base body 213.

[0056] Combination Figure 4 As shown, an ejection mechanism 23 is provided inside the second mold base body 221;

[0057] like Figure 4 and Figure 5 As shown, the ejection mechanism 23 includes several ejection components 233 disposed within the mold groove 222. These ejection components 233 are connected to the same air path via a pipe 234. A first interface 231 and a second interface 232 are respectively installed at the pipe openings of the pipe 234. The ejection mechanism 23 is connected to an external pneumatic drive system via the second interface 232 and the first interface 231. It should be noted that, in this embodiment, the pneumatic drive system includes an air pump connected to the first interface 231 and a pressure relief valve installed on the second interface 232.

[0058] The ejector assembly 233 includes a sleeve installed in the pipe 234, a piston and a return spring for driving the piston to return to its original position are provided inside the sleeve, and a push rod is fixed to the other end of the piston. The push rod is flush with the side of the mold groove 222.

[0059] After the first mold base body 213 separates from the second mold base body 221, the piston moves along the sleeve through the air pump and the pipe 234 to compress the return spring. During the movement of the ejector rod, the molded part is ejected from the mold groove 222, thereby realizing the demolding process. Furthermore, the first mold base body 213 is reset by the drive cylinder 211 to enter the next injection molding process. The corresponding injection nozzle 32 is opened to realize the repeated injection molding process. During this process, the injection molding machine body 10 does not need to stop, which greatly improves the production efficiency.

[0060] Combination Figure 6 As shown, an electric heating wire 34 is installed inside the main body of the pipe 33. The electric heating wire 34 is used to prevent the molten medium from solidifying and blocking the injection molding pipeline 30, thus avoiding disruption to the normal working process.

[0061] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0062] The above specific embodiments are merely one or more preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
