[0035] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0036] In the present disclosure, for the convenience of description, a first direction and a second direction are defined for an injection molding machine, wherein reference is made to Figure 1 As shown, "X" represents the first direction, and "Y" represents the second direction. Unless otherwise specified, "inside" and "outside" refer to the inside and outside of the corresponding component's outline; "far" and "near" refer to the spatial distance of the corresponding component relative to another component. Furthermore, the terms "first," "second," and so on, used in this disclosure, are intended to distinguish one element from another and do not convey sequential or significant meaning. In the following description referring to the drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements.

[0037] Hereinafter, an injection molding machine in an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0038] refer to Figures 1 to 4 As shown, the present disclosure provides an injection molding machine 10 , which includes a base 1 , an injection assembly 2 , a mold assembly 3 and a pipe assembly 4 .

[0039] The injection assembly 2 includes a drive mechanism 21 at least partially located within the base 1;

[0040] The mold assembly 3 is located on one side of the base 1 along the first direction;

[0041] The pipeline assembly 4 includes a heat exchange main pipe group 41 and a heat exchange branch pipe group 42. The heat exchange main pipe group 41 is connected to the mold assembly 3 and / or the injection assembly 2 through the heat exchange branch pipe group 42. The heat exchange main pipe group 41 passes through the base 1 along the first direction.

[0042] Through the above technical solution, the mold assembly 3 is located on one side of the base 1 along the first direction. Accordingly, the heat exchange main pipe group 41 penetrates the base 1 along the first direction, utilizing the space within the base 1 to arrange the heat exchange main pipe group 41. This allows the heat exchange main pipe group 41 to be at least partially concealed within the base 1 of the injection molding machine 10, thereby reducing the external space occupied and improving the space utilization within the base 1. In addition, arranging the heat exchange main pipe group 41 within the base 1 facilitates the arrangement of the heat exchange branch pipe group 42, so that the heat exchange branch pipe group 42 can be used to separate the mold assembly 3 and the injection assembly 2 for heat exchange.

[0043] In an exemplary application environment, the injection molding machine 10 can be constructed as a screw-type injection molding machine 10, wherein the injection assembly 2 can include a screw structure, which is installed above the base 1. The screw structure includes a screw and a barrel. First, the granular or powdered plastic is added into the barrel through the discharge port, and the plastic is molten by the rotation of the screw and the heating of the outer wall of the barrel. At this time, the heat exchange main pipe group 41 can perform heat exchange cooling on the feed port through the heat exchange branch pipe group 42 for cooling the injection assembly 2, so as to prevent the raw material from melting at the discharge port, resulting in the inability to discharge the raw material normally.

[0044] Then the mold assembly 3 of the injection molding machine 10 is closed, and the injection assembly 2 moves forward so that the nozzle is close to the gate of the mold assembly 3. Then, pressurized oil is introduced into the injection cylinder to advance the screw, thereby injecting the molten material into the mold assembly 3 with a lower temperature at a very high pressure and a faster speed. At this time, the heat exchange main pipe group 41 can perform heat exchange cooling on the mold through the heat exchange branch pipe group 42 used to cool the mold assembly 3, so that the raw material is solidified and formed. Finally, the mold can be opened to take out the molded product.

[0045] In some embodiments, reference Figure 1 As shown, the base 1 has an installation space within it, and the drive mechanism 21 and the heat exchange manifold assembly 41 can be arranged side by side within the installation space along a second direction, which is perpendicular to the first direction. This allows the heat exchange manifold assembly 41 to be concealed, facilitating installation of the heat exchange manifold assembly 41 and the drive mechanism 21. The heat exchange manifold assembly 41 can also be integrated during installation of the base 1, improving the integrity of the injection molding machine 10. For example, the drive mechanism 21 can include a drive motor for driving the screw. In this case, the heat exchange branch assembly 42 can include a heat exchange branch for heat exchange cooling the aforementioned discharge port and a heat exchange branch for heat exchange cooling the drive motor.

[0046] It can be understood that by arranging the heat exchange main pipe group 41 in the installation space inside the base 1, the heat exchange main pipe group 41 can be protected by the base 1 to reduce the possibility of the heat exchange main pipe group 41 being damaged or destroyed by accidental contact by the operator or impact by external objects, thereby ensuring the normal operation of the heat exchange main pipe group 41.

[0047] In some embodiments, reference Figure 1 As shown, the base 1 has an operating side and a non-operating side that are opposite to each other along the second direction. The base 1 is connected to a control console on the operating side, wherein the control console can be used to control the drive mechanism 21. In this way, the drive mechanism 21 can be arranged near the operating side, and the heat exchange manifold group 41 can be arranged near the non-operating side, so as to facilitate the reasonable installation of the heat exchange manifold group 41 and the drive mechanism 21. Exemplarily, the drive mechanism 21 may include a linear drive member for driving the above-mentioned barrel movement and a rotary drive member for rotating the above-mentioned screw. The linear drive member and the rotary drive member can be arranged along the first direction to facilitate the installation of the heat exchange manifold group 41, reduce the size of the base 1 in the second direction, and thus reduce the overall space occupied by the injection molding machine 10.

[0048] In some embodiments, reference Figure 1 As shown, the pipe assembly 4 further includes an exhaust pipe 43 disposed within the installation space and extending through the base 1 in a first direction, with the heat exchange manifold assembly 41 located below the exhaust pipe 43. Furthermore, the pipe assembly 4 further includes an intake pipe 44 disposed within the installation space and extending through the base 1 in a first direction, with the intake pipe 44 located between the heat exchange manifold assembly 41 and the drive mechanism 21. In this manner, the exhaust pipe 43 and intake pipe 44 of the injection molding machine 10 are at least partially integrated within the base 1, thereby improving the integrity of the injection molding machine 10. The exhaust pipe 43 requires a larger size and can therefore be placed above the heat exchange manifold assembly 41 to facilitate exhaust gas discharge. The intake pipe 44 requires a smaller size and can therefore be placed between the heat exchange manifold assembly 41 and the drive mechanism 21.

[0049] During the injection molding process, plastic materials undergo physical and chemical changes at high temperatures. Many plastic materials, such as polyvinyl chloride (PVC) and polystyrene (PS), release volatile organic compounds (VOCs) when heated. These VOCs include monomers, oligomers, and small molecules produced by the decomposition of additives. Exhaust pipe 43 promptly discharges these harmful volatile gases from the working area of ​​injection molding machine 10 to prevent their accumulation in the workshop.

[0050] Furthermore, to facilitate the smooth release of plastic products from the mold, a release agent is typically used. This release agent also evaporates on the high-temperature mold surface. Exhaust pipe 43 allows the evaporation of these release agent gases to prevent them from affecting the quality of the plastic product. If the release agent volatile gases are not promptly exhausted, they may adhere to the surface of the plastic product, causing surface defects such as oil spots and increased haze.

[0051] In the injection molding machine 10, many components rely on cylinders to realize their movements, such as the opening and closing movements of the mold assembly 3, which requires sufficient air pressure to provide strong power to ensure that the mold can be opened and closed quickly and stably. The air inlet pipe 44 can deliver compressed air to the mold opening and closing cylinder. When the compressed air enters one side of the cylinder, it will push the piston to move, thereby driving the opening and closing of the mold 32.

[0052] After the injection molding is completed, the product needs to be ejected from the mold. The air inlet pipe 44 can also provide power to the cylinder of the ejection device so that the ejector pin can push the product out of the mold according to the set program. This can ensure smooth demolding of the product and can adapt to the ejection requirements of products of different shapes and sizes.

[0053] In some embodiments, reference Figure 1 As shown, the base 1 has two side walls arranged opposite each other along a first direction, and the heat exchange main pipe group 41 passes through the two side walls. In this way, the two side walls can support the heat exchange main pipe group 41 and fix it in the second direction. In addition, the heat exchange main pipe group 41 can be connected to the base 1 via the pipe fixing bracket 5 inside the base 1.

[0054] The pipe fixing frame 5 can be constructed in any suitable manner. For example, Figure 1 and Figure 5 As shown, the pipe fixing bracket 5 may include a base member connected to the base 1. The base member may be, for example, an I-beam or channel steel, and an annular member connected to the base member and surrounding a portion of the outer wall of the pipe of the heat exchange main pipe group 41 for fixing the pipe to the base member. It is understood that the base member may be connected to the bottom wall of the base 1 and extend in a third direction perpendicular to the first direction and the second direction. In this case, the annular member may be arranged on opposite sides of the base member along the second direction for fixing the heat exchange main pipe group 41. Alternatively, the base member may be connected to the side wall of the non-operating side of the base 1 and extend in the second direction. In this case, the annular member may be arranged on opposite sides of the base member along the third direction for fixing the heat exchange main pipe group 41. Alternatively, the pipe fixing bracket 5 may adopt any existing suitable pipe fixing bracket 5.

[0055] In some embodiments, reference Figure 1 and Figure 2As shown, there are multiple heat exchange main pipe groups 41, and the multiple heat exchange main pipe groups are arranged side by side in the vertical direction. In this way, the space occupied by the heat exchange main pipe groups 41 in the second direction can be reduced, thereby reducing the volume of the base 1 and improving the integrity of the injection molding machine 10.

[0056] The multiple heat exchange manifold groups 41 may include a first heat exchange manifold group 411, which is used to connect to the mold assembly 3 for cooling the mold assembly 3; and / or, the multiple heat exchange manifold groups 41 may include a second heat exchange manifold group 412, which is used to connect to the injection assembly 2 for cooling the injection assembly 2; and / or, the multiple heat exchange manifold groups 41 may include a third heat exchange manifold group 413, which is used to connect to the mold assembly 3 for heating or cooling the mold assembly 3. In this way, the present disclosure exemplarily arranges the multiple heat exchange manifold groups 41 for cooling the mold assembly 3 and the injection assembly 2 in a hidden manner within the base 1, and the first heat exchange manifold group 411, the second heat exchange manifold group 412, and the third heat exchange manifold group 413 may be arranged side by side in sequence along the vertical direction.

[0057] refer to Figure 1 and Figure 2 As shown, equipment cooling water can flow inside the second group of heat exchange main pipes 412, which have an inlet pipe and an outlet pipe. The inlet water flows through the injection assembly 2, such as the above-mentioned screw and drive mechanism 21, etc., and can be used to cool the discharge port and the drive motor, and then flows back to the refrigeration equipment such as a cooling tower through the outlet pipe for cooling, so as to realize the recycling of equipment cooling water.

[0058] refer to Figures 1 to 4 As shown, mold cooling water can flow through the interior of the first group of heat exchange main pipes 411, which has a first water inlet pipe 4111 and a first water outlet pipe 4112. The mold cooling water flows to the mold assembly 3 through the first water inlet pipe 4111 to cool the molded product. The cooling water after heat exchange flows back to the refrigeration equipment such as a cooling tower through the first water outlet pipe 4112 for cooling. Normal temperature water can flow through the interior of the third group of heat exchange main pipes 413, which has a second water inlet pipe 4131 and a second water outlet pipe 4132. The second water inlet pipe 4131 is connected to the mold assembly 3 through the mold temperature controller 20. The normal temperature water after heat exchange flows back to the mold temperature controller 20 through the second water outlet pipe 4132 for reuse or discharge.

[0059] For example, when the surface requirements of the molded product are low, the mold assembly 3 can be cooled by normal temperature water. At this time, the mold temperature controller 20 is in a closed state, that is, it can exchange heat to cool the mold assembly 3 and mold the product; when the surface requirements of the molded product are high, the first group of heat exchange main pipes 411 can be connected, that is, the mold assembly 3 is cooled by mold cooling water to meet the cooling needs of the mold assembly 3 at this time; when the surface requirements of the molded product are higher, the mold temperature controller 20 is turned on to heat the normal temperature water to heat the mold assembly 3 and ensure the fluidity of the molten material in the mold assembly 3, and then the mold assembly 3 is cooled by the mold cooling water so that the molded product can be molded with a high-quality high-gloss surface.

[0060] In some embodiments, reference Figure 1 and Figure 2 As shown, the number of heat exchange branch pipe groups 42 can be multiple groups, and the multiple groups of heat exchange branch pipes include a first group of heat exchange branch pipes 421, which is connected to the first integrated component 6, and / or the multiple groups of heat exchange branch pipes 42 include a second group of heat exchange branch pipes 422, which is connected to the second integrated component 7. In this way, the first group of heat exchange branch pipes 421 can be integrated through the first integrated component 6, and the heat exchange branch pipes of the movable mold 32 can be integrated through the second integrated component 7, so as to be able to regularize the multiple groups of heat exchange branch pipes 42 and improve the integrity of the injection molding machine 10.

[0061] For example, the first set of heat exchange branch pipes 421 may include a static mold cooling water inlet pipe 4211 and a static mold cooling water outlet pipe 4212 for cooling the static mold 31, as well as a static mold normal-temperature water inlet pipe 4213 and a static mold normal-temperature water outlet pipe 4214 for cooling or heating the static mold 31. The second set of heat exchange branch pipes 422 may include a movable mold cooling water inlet pipe 4221 and a movable mold cooling water outlet pipe 4222 for cooling the movable mold 32, as well as a movable mold normal-temperature water inlet pipe 4223 and a movable mold normal-temperature water outlet pipe 4224 for cooling or heating the movable mold 32. Among them, the static mold cooling water inlet pipe 4211 and the dynamic mold cooling water inlet pipe 4221 are both connected to the first water inlet pipe 4111, the static mold cooling water outlet pipe 4212 and the dynamic mold cooling water outlet pipe 4222 are both connected to the first water outlet pipe 4112, the static mold normal temperature water inlet pipe 4213 and the dynamic mold normal temperature water inlet pipe 4223 are both connected to the second water inlet pipe 4131, and the static mold normal temperature water outlet pipe 4214 and the dynamic mold normal temperature water outlet pipe 4224 are both connected to the second water outlet pipe 4132. The present disclosure exemplarily sets the number of the static mold cooling water inlet pipe 4211, static mold cooling water outlet pipe 4212, static mold normal temperature water inlet pipe 4213 and static mold normal temperature water outlet pipe 4214, as well as the movable mold cooling water inlet pipe 4221, movable mold cooling water outlet pipe 4222, movable mold normal temperature water inlet pipe 4223 and movable mold normal temperature water outlet pipe 4224 to be single. It can be understood that the number of the above-mentioned pipelines can also be set to multiple, and the present disclosure does not make specific limitations on this.

[0062] Furthermore, the first integrated assembly 6 is configured to separate the heat exchange branches in the first group of heat exchange branches 421 into two parts, and / or the second integrated assembly 7 is configured to separate the heat exchange branches in the second group of heat exchange branches 422 into two parts. In this way, the heat exchange branches in the first group of heat exchange branches 421 and the heat exchange branches in the second group of heat exchange branches 422 can be separated to disconnect the water circuit and replace the corresponding pipe section.

[0063] It can be understood that the number of heat exchange branches in the first group of heat exchange branches 421 and the number of heat exchange branches in the second group of heat exchange branches 422 can be set to multiple, and the diversion of multiple heat exchange branches can be achieved by, for example, a water distributor or other diversion structure. The present disclosure does not make specific limitations on this.

[0064] In some embodiments, reference Figure 1 and Figure 2As shown, the first integrated assembly 6 may include a first integrated plate 61 and a plurality of first quick connectors 62. The heat exchange branches of the first group of heat exchange branches 421 include a first front section and a first rear section, which are connected via corresponding first quick connectors 62. One of the first male connector and the first female connector of the first quick connector 62 is connected to the first integrated plate 61 and the first front section, while the other is connected to the first rear section. The first rear section is connected to the static mold 31 of the mold assembly 3. In this way, the multiple heat exchange branches of the first group of heat exchange branches 421 can be integrated into the first integrated plate 61, and the heat exchange branches include a first front section and a first rear section that are detachably connected via the first quick connector 62. This allows for rapid installation and replacement of the heat exchange branches via the first quick connector 62, making the installation and replacement process relatively simple and quick.

[0065] Similarly, the second integrated assembly 7 may include a second integrated plate 71 and a plurality of second quick connectors 72. The heat exchange branches of the second group of heat exchange branches 422 include a second front section and a second rear section, which are connected via corresponding second quick connectors 72. One of the second male connector and the second female connector in the second quick connector 72 is connected to the second integrated plate 71 and the second front section, while the other is connected to the second rear section. The second rear section is connected to the movable mold 32 of the mold assembly 3. In this way, the plurality of heat exchange branches of the second group of heat exchange branches 422 can be integrated into the second integrated plate 71, and the heat exchange branches include a second front section and a second rear section that are detachably connected via the second quick connectors 72. This allows for rapid installation and replacement of the heat exchange branches via the second quick connectors 72, making the installation and replacement process relatively simple and quick.

[0066] In some embodiments, reference Figure 1 and Figure 2 As shown, the first integrated component 6 and / or the second integrated component 7 are provided with an oil circuit connector 8 and / or an electric circuit connector 9. Thus, the multiple heat exchange branches of the first group of heat exchange branches 421, as well as the oil circuit connector 8 and the electric circuit connector 9 for the static mold 31, can be integrated through the first integrated component 6. The multiple heat exchange branches of the first group of heat exchange branches 421, as well as the oil circuit connector 8 and the electric circuit connector 9 for the static mold 31, can be integrated into the aforementioned first integrated board 61. Similarly, the multiple heat exchange branches of the second group of heat exchange branches 422, as well as the oil circuit connector 8 and the electric circuit connector 9 for the movable mold 32, can be integrated through the second integrated component 7. The multiple heat exchange branches of the second group of heat exchange branches 422, as well as the oil circuit connector 8 and the electric circuit connector 9 for the movable mold 32, can be integrated into the aforementioned second integrated board 71.

[0067] It is understood that the oil circuit connector 8 can be a quick connector to reduce the waste of oil in the oil circuit when disconnected and improve the utilization rate. The circuit connector 9 can be a signal line plug for convenient connection of the circuit. The present disclosure is not limited to this.
