Description

Technical Field

[0001] This application relates to the field of injection molding temperature control technology, specifically to a liquid silicone injection molding temperature control device. Background Technology

[0002] Liquid silicone injection molding is a highly efficient thermosetting molding technology that processes liquid silicone rubber into silicone products through injection molding. During the silicone injection molding process, that is, during the process of conveying the silicone from the delivery pipe to the mold, the temperature of the silicone needs to be controlled to ensure the fluidity of the silicone.

[0003] For example, patent CN214926857U discloses a temperature control device for injection molds. This device connects an external material pipe to a feed pipe, allowing the material to enter the processing cylinder. Simultaneously, a temperature sensor detects the temperature of the material, and a motor drives a rotating rod and an auger to rotate, moving the external material to the left. During this movement, the material comes into contact with an annular temperature-conducting plate. When the external material temperature is too low, the heating plate is energized and turns on, transferring the temperature to the inside of the processing cylinder through the annular temperature-conducting plate to heat the material inside. When the external material temperature suddenly increases, the heating plate turns off, and then the cooling fan is energized and turns on, drawing in air from around the processing cylinder and blowing it onto the heat dissipation fins. The heat dissipation fins cool the material inside the processing cylinder through the annular temperature-conducting plate, thus achieving good temperature control.

[0004] Although the aforementioned patent can achieve temperature control, since the fan's heat dissipation vents are always exposed to the air, the fins are still dissipating heat from the raw materials while they are being heated, resulting in a conflict between heating and cooling, which reduces the heating effect and increases the energy consumption required.

[0005] Therefore, it is necessary to provide a liquid silicone injection molding temperature control device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a liquid silicone injection molding temperature control device to achieve the effect of sealing the heat dissipation port.

[0008] The technical solution adopted by this application to solve its technical problem is: a liquid silicone injection molding temperature control device, including an injection molding machine; a temperature control component, which is disposed on the injection molding machine and has a housing suitable for isolation; a heat dissipation component, which is disposed on the housing and includes: at least two sets of mounting blocks, which are mounted on both sides of the housing; two sets of electric cylinders, which are mounted inside the mounting blocks and have push rods mounted on their output ends; two sets of sealing doors, which are connected to one end of the push rods, and heat dissipation vents are provided through both sides of the housing; at least two sets of slide rails, which are mounted on both sides of the housing and have the sealing doors slidably disposed on the slide rails; and two sets of fans, which are mounted inside the housing.

[0009] Furthermore, the sealing door is located on the outside of the heat dissipation vent, the fan is located on the inside of the heat dissipation vent, and the outer shell is composed of two sets of semi-circular arc plates spliced ​​together.

[0010] Furthermore, the temperature control component includes a hopper installed on the injection molding machine, and a material delivery pipe is installed at the outlet of the hopper.

[0011] Furthermore, the feed pipe is equipped with at least two sets of electric heating coils, each with an interface. At least two sets of bases are installed inside one set of arc plates, with each set of bases located below the at least two sets of electric heating coils.

[0012] Furthermore, the base is equipped with two sets of sockets, which are electrically connected to each other, and the sockets are hinged with flip covers.

[0013] Furthermore, two sets of end plates are installed on the conveying pipe, and the two ends of the outer shell are detachably installed on the two sets of end plates.

[0014] The beneficial effects of this application are: the liquid silicone injection molding temperature control device provided by this application can dissipate heat inside the shell through the setting of heat dissipation components, and can seal the heat dissipation port when heat dissipation is not required, so as to avoid heat loss during heating and achieve the effect of sealing the heat dissipation port.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1 and Figures 3-4 As shown, this application provides a liquid silicone injection molding temperature control device, including an injection molding machine 1. The injection molding machine 1 is prior art, and its specific structure and principle will not be described in detail. The injection molding machine 1 has a temperature control component 2 suitable for heating silicone.

[0029] Temperature control assembly 2 includes a hopper 22 fixedly installed on injection molding machine 1. The interior of the hopper 22 is suitable for storing silicone, and a conveying pipe 23 is fixedly installed at the outlet of the hopper 22. Figure 4The end of the conveying pipe 23 away from the hopper 22 is connected to the subsequent mold equipment so that the silicone in the hopper 22 can be conveyed to the mold equipment through the conveying pipe 23 for injection molding.

[0030] Multiple sets of electric heating coils 24 are provided on the feed pipe 23. Each electric heating coil 24 has an interface (not shown in the figure) so that the interface can be connected to an external power source through a wire harness, thereby energizing and heating the electric heating coil 24, which in turn heats the feed pipe 23 to heat the silicone.

[0031] Two sets of end plates 25 are fixedly installed at both ends of the outer ring of the conveying pipe 23. A shell 21 is detachably installed on both sets of end plates 25. The shell 21 is formed by splicing two sets of semi-circular arc plates to form a cylindrical shell that wraps around the conveying pipe 23, and the end plates 25 seal the two ends of the cylindrical shell.

[0032] This allows the heating area to be isolated from the outside world when the electric heating coil 24 heats the feed pipe 23, preventing heat loss and thus reducing the heating effect. Also, when maintenance is required, the outer shell 21 can be separated for repair.

[0033] Continue to refer to Figure 4 Multiple sets of bases 28 are fixedly installed inside one of the arc plates. The multiple sets of bases 28 are located below the multiple sets of electric heating coils 24. Two sets of sockets 27 are provided on the bases 28. The two sets of sockets 27 are electrically connected to each other so that when the length of the wire harness is insufficient, the interface of the electric heating coil 24 can be connected to one set of sockets 27 through the wire harness, and the other set of sockets 27 can be connected to the external power source through the wire harness for conversion.

[0034] A flip cover 26 is hinged to the socket 27. The flip cover 26 can move closer to or further away from the socket 27. When it is close to the socket 27, it can close the socket 27 to prevent dust and other impurities from contaminating the socket 27.

[0035] A heat dissipation component 3 is provided on the outer casing 21, which is adapted to dissipate heat from the outer casing 21;

[0036] like Figures 1-2 As shown, the heat dissipation component 3 includes heat dissipation vents (not shown in the figure) that pass through both sides of the outer casing 21, and two sets of fans 36 are fixedly installed on the inner wall of the outer casing 21. The two sets of fans 36 are located inside the two sets of heat dissipation vents, so that when the internal temperature of the outer casing 21 is too high, the fans 36 will be activated to dissipate the heat inside the outer casing 21 to the outside.

[0037] Multiple sets of mounting blocks 31 are fixedly installed on both sides of the outer casing 21. An electric cylinder 32 is fixedly installed inside the mounting block 31. A push rod 34 is fixedly installed at the output end of the electric cylinder 32. A sealing door 35 is fixedly installed at the end of the push rod 34 away from the electric cylinder 32. The sealing door 35 is located outside the heat dissipation vent.

[0038] Two sets of slide rails 33 are fixedly installed on both sides of the outer shell 21. The two sets of slide rails 33 are located on both sides of the heat dissipation vent, and the closed door 35 is slidably mounted on the slide rails 33.

[0039] Then, driven by the electric cylinder 32, the drive rod 34 drives the closed door 35 to move on the slide rail 33, so that it moves closer to or away from the heat dissipation vent, thereby opening or closing the heat dissipation vent.

[0040] It should be noted that sealing strips are provided on all four sides of the closed door 35 near the outer shell 21 to ensure the airtightness of the outer shell 21. Temperature sensors are also provided inside the feed pipe 23 and the outer shell 21 to detect the internal temperature. This is existing technology, and the specific principle and structure will not be described in detail here.

[0041] In summary, during the process of conveying the silicone in the hopper 22 to the subsequent mold equipment through the conveying pipe 23, the electric heating coil 24 can be energized to heat the conveying pipe 23. When the internal temperature of the conveying pipe 23 is too high, the electric cylinder 32 is activated to move the closed door 35 away from the heat dissipation vent to open the heat dissipation vent. At this time, the fan is activated to quickly dissipate the heat inside the outer shell 21, thereby cooling the conveying pipe 23.

[0042] When heat dissipation is not required, the electric cylinder 32 can be activated to close the heat dissipation vents via the sealing door 35, thereby isolating the interior space of the outer casing 21 from the outside environment and preventing heat loss during heating. The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
