Description

Technical Field

[0001] This invention relates to the field of injection molding technology, specifically to an injection molding device for monitor housings with temperature control function. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are typically made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Traditional injection molding equipment often suffers from problems such as inaccurate temperature control, difficulty in demolding after product molding, and uneven mixing of raw materials when producing monitor housings. Furthermore, existing injection molding equipment cannot recycle residual raw materials during the injection process. The residual molten plastic will slowly solidify in the pipes. Over time, this will lead to a decrease in injection speed, an increase in impurities, and in severe cases, pipe blockage. In addition, some existing injection molding devices require manual demolding after injection, which reduces work efficiency. A few automated devices require additional equipment to apply pressure to the side of the mold during demolding, making the equipment cumbersome. When maintaining or replacing parts, it is inconvenient for staff to perform maintenance or replacement. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

The mixing component runs continuously in the mixing tank to fully integrate different plastic particles or additives, preparing for the subsequent injection molding step. After mixing is completed, the extrusion component starts, driving the upper mold to move downward and closely cooperate with the lower mold. The injection component starts working, conveying the mixed material between the lower mold and the upper mold. The injection process needs to be precisely controlled to ensure that the amount of injected material meets the design requirements of the monitor housing. 2. After the material cools and solidifies in the mold, the extrusion component moves the upper mold upward, and then the pusher component starts working. It pushes the formed monitor shell out of the lower mold, which is convenient for subsequent removal and further processing. During the entire injection molding process, the device can evenly stir the material to prevent the plastic melt from clumping, which would cause the final product to fail to meet the standards. In addition, the recycling component can recover the residual raw materials in the injection tube to prevent the plastic melt from solidifying in the injection tube, thereby saving raw material consumption. 3. During use, the ejector assembly utilizes the pressure of the coolant to push the ejector block to slide within the ejector tube. Because the ejector block is slidably connected to the limiting groove, the limiting groove provides excellent guidance, ensuring the ejector block does not deviate during sliding, thus guaranteeing the stability and accuracy of the ejection action. When the coolant pressure pushes the ejector block into the mold, the ceramic material at the output end of the ejector block has excellent wear resistance and high-temperature resistance, preventing damage to the surface of the molded monitor housing when it comes into contact with it, thus ensuring the appearance quality of the monitor housing. Under the pressure of the coolant, the ejector block smoothly ejects the molded monitor housing from the lower mold, achieving an efficient demolding process. Furthermore, the coordinated work of the ejector assembly and the cooling assembly makes the entire injection molding equipment's production process more compact and efficient, reducing the production cycle and improving production efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example: Figures 1-8 As shown, the present invention provides a technical solution for an injection molding equipment for a monitor housing with temperature control function, including an injection molding equipment body 1 and a control device 9. The injection molding equipment body 1 includes a frame 11, a mixing tank 12 and a lower mold 13 are installed on the frame 11, a mixing component 2 is installed inside the mixing tank 12, an injection component 3 is connected to the output end of the mixing tank 12, the injection component 3 is connected to the lower mold 13, a pusher component 4 is provided inside the lower mold 13, a cooling component 5 is installed above the frame 11, the cooling component 5 cooperates with the pusher component 4, an extrusion component 6 is installed above the frame 11, an upper mold 62 is installed at the output end of the extrusion component 6, and the upper mold 62 cooperates with the lower mold 13. Therefore, when using this device, the mixing tank 12 is first required to mix the raw materials to ensure the uniformity of the materials. The mixing component 2 operates continuously in the mixing tank 12 to fully integrate different plastic particles or additives, preparing for the subsequent injection molding step. After mixing is completed, the extrusion component 6 is started, which drives the upper mold 62 to move downward and closely cooperate with the lower mold 13. The injection component 3 starts to work, which transports the mixed material between the lower mold 13 and the upper mold 62. The injection process needs to be precisely controlled to ensure that the amount of injected material meets the design requirements of the monitor housing. Then, the cooling component 5 will inject coolant into the cooling circuit between the upper mold 62 and the lower mold 13, so that the coolant can flow in the cooling circuit. During the flow of the coolant, it can continuously absorb the heat in the upper mold 62 and the lower mold 13, thereby accelerating the molding of the mold. After the material cools and solidifies in the mold, the extrusion component 6 moves the upper mold 62 upward, and then the pusher component 4 starts working, pushing the formed monitor shell out of the lower mold 13 for easy removal and further processing. Throughout the injection molding process, the device can evenly stir the material during use, preventing the plastic melt from clumping and causing the final product to fail to meet standards. Furthermore, the recycling component 7 can recover residual raw materials in the injection tube 32, preventing the plastic melt from solidifying in the injection tube 32, thereby saving raw material consumption.

[0019] like Figures 1-2 and Figure 4 As shown, in this embodiment, specifically, the cooling component 5 includes a cooling box 51, a cooling pump 52 is installed at the output end of the cooling box 51, a cooling circuit and a pushing component 4 are provided inside the lower mold 13, the cooling circuit is connected to the cooling pump 52 and the cooling box 51, and the pushing component 4 is connected to the cooling circuit through a valve. Therefore, when the device is in use, the cooling component 5 can effectively regulate the temperature of the lower mold 13, ensuring the cooling speed and quality of the material during the injection molding process. After the injection material is injected into the lower mold 13, the coolant in the cooling box 51 is transported to the cooling circuit through the cooling pump 52. The coolant circulates in the circuit, carrying away the heat in the mold and allowing the material to cool and solidify quickly. Since the pusher component 4 is connected to the cooling circuit through a valve, after the material has cooled to a certain degree, the pressure of the coolant can be used to control the valve to open and push the pusher component 4 to push the formed monitor shell out of the lower mold 13, achieving automatic demolding. This design not only improves production efficiency but also reduces manual intervention and labor intensity. At the same time, the temperature control function of the cooling component 5 can accurately adjust the flow rate and temperature of the coolant according to different injection materials and process requirements to adapt to various production needs and ensure that the produced monitor shells have stable quality and reliable performance.

[0020] like Figures 4-5 As shown, in this embodiment, specifically, the pusher assembly 4 includes a pusher tube 41, which is connected to the cooling circuit via a valve. The other end of the pusher tube 41 is located inside the mold. A limit groove is provided on the inner wall of the pusher tube 41. A pusher block 42 is provided inside the pusher tube 41. The pusher block 42 is slidably connected to the limit groove. The output end of the pusher block 42 is made of ceramic material. When the pusher assembly 4 is not working: the output end of the pusher block 42 is embedded in the inner wall of the lower mold 13; When in use, the pusher assembly 4 can push the pusher block 42 to slide inside the pusher tube 41 with the help of the coolant pressure. Since the pusher block 42 is slidably connected to the limiting groove, the limiting groove plays a good guiding role for the pusher block 42, ensuring that the pusher block 42 will not deviate during the sliding process, thereby ensuring the stability and accuracy of the pusher action. When the coolant pressure pushes the pusher block 42 to slide into the mold, the ceramic material at the output end of the pusher block 42 has good wear resistance and high temperature resistance, which can avoid damage to the surface of the molded monitor shell when it comes into contact with it, thus ensuring the appearance quality of the monitor shell. Under the action of coolant pressure, the pusher block 42 smoothly pushes the molded monitor shell out of the lower mold 13, realizing an efficient demolding process. Moreover, the coordinated work of the pusher assembly 4 and the cooling assembly 5 makes the entire injection molding equipment production process more compact and efficient, reduces the production cycle, and improves production efficiency.

[0021] like Figure 1 and Figure 4 As shown, in this embodiment, specifically, the extrusion assembly 6 includes an extrusion cylinder 61. The fixed end of the extrusion cylinder 61 is connected to the frame 11. An upper mold 62 is installed at the output end of the extrusion cylinder 61. The upper mold 62 and the lower mold 13 cooperate with each other. There is a mold cavity on the output surface of the upper mold 62 and the lower mold 13. Plastic melt is injected into the mold cavity. A cooling circuit is also provided inside the upper mold 62. The two cooling circuits work together, and a valve is provided at the connection between the cooling circuit of the lower mold 13 and the cooling circuit of the upper mold 62; When producing monitor housings, the device first requires the extrusion assembly 6 to activate the extrusion cylinder 61, causing its output end to drive the upper mold 62 downwards, tightly fitting it with the lower mold 13. At this time, a complete mold cavity is formed between the upper mold 62 and the lower mold 13. Since molten plastic has been injected into the mold cavity, the pressure applied by the extrusion assembly 6 will cause the molten plastic to fully fill every corner of the mold cavity, ensuring the integrity of the monitor housing shape and the tightness of the structure. At the same time, the cooling circuit inside the upper mold 62 begins to function, cooperating with the cooling circuit inside the lower mold 13 to cool the molten plastic inside the mold.

[0022] like Figures 1-3As shown, in this embodiment, specifically, the mixing tank 12 is provided with a limiting groove 121 inside, the mixing component 2 cooperates with the limiting groove 121, the bottom of the mixing tank 12 is provided with a discharge port, the discharge port is connected to the injection component 3, and a heating wire is provided inside the inner wall of the mixing tank 12. Before injection molding the monitor casing, a plastic melt needs to be prepared in a mixing tank 12. Various raw materials required for making the monitor casing are added into the mixing tank 12 in a certain proportion. Since there is a heating wire in the inner wall of the mixing tank 12, the heating wire starts to work and heats the raw materials to reach a suitable melting temperature, thereby forming a plastic melt. At the same time, the stirring component 2 operates stably with the cooperation of the limiting groove 121, and fully stirs the raw materials in the tank to ensure that the raw materials are mixed evenly and to ensure the quality of the plastic melt is stable. The evenly stirred plastic melt enters the injection component 3 through the discharge port at the bottom of the mixing tank 12. The injection component 3 accurately injects the plastic melt into the mold cavity formed by the lower mold 13 and the upper mold 62, preparing for the subsequent molding of the monitor casing.

[0023] like Figure 3 As shown, in this embodiment, specifically, the injection component 3 includes an injection pump 31 and an injection pipe 32. The input end of the injection pump 31 is connected to the bottom outlet of the mixing tank 12, the output end of the injection pump 31 is connected to the injection pipe 32, the other end of the injection pipe 32 is connected to the lower mold 13, a recycling component 7 is provided inside the injection pipe 32, a discharge port is provided at the bottom of the injection pipe 32 through a valve, and threaded grooves are provided on the inner wall and outer wall of the injection pipe 32 respectively. When the injection assembly 3 is in use, the injection pump 31 starts and draws the uniformly stirred plastic melt in the mixing tank 12 out of the outlet and transports it to the lower mold 13 through the injection pipe 32. The threaded grooves on the inner and outer walls of the injection pipe 32 can increase the structural strength of the injection pipe 32 so that it can withstand the pressure during the plastic melt transportation process, thereby completing the injection of the plastic melt. On the other hand, the threaded groove can also play a certain buffering role, reducing the impact of the plastic melt on the injection tube 32 when it flows, extending the service life of the injection tube 32, and can work with the recycling component 7 to recycle excess plastic melt.

[0024] like Figures 1-2 and Figures 6-7As shown, in this embodiment, specifically, the recycling component 7 includes a recycling motor 71, a drive screw 72 is installed at the output end of the recycling motor 71, a drive gear 73 is provided on the drive screw 72, a drive ring 74 is threadedly connected to the injection pipe 32, the drive ring 74 is connected to the drive gear 73, a recycling ring 75 is threadedly connected inside the injection pipe 32, multiple sets of magnets are respectively provided on the side of the drive ring 74 and the mating ring, the magnetic poles of the two connected sets of magnets are arranged in opposite directions, and a recycling bin 76 is installed at the bottom of the injection pipe 32, the recycling bin 76 is located at the bottom of the discharge port; The recycling component 7 can recycle excess molten plastic. In practical use, the recycling motor 71 starts, driving the drive screw 72 to rotate. The drive gear 73 on the drive screw 72 rotates accordingly. Since the drive ring 74 is connected to the drive gear 73, the drive gear 73 drives the drive ring 74 to rotate. Because multiple sets of magnets with opposite magnetic poles are respectively installed on the side of the drive ring 74 and the mating ring, under the action of magnetic force, the drive ring 74 drives the recycling ring 75 to move within the injection tube 32. After injection is completed, the excess molten plastic remains in the injection tube. Inside the material pipe 32, the recovery ring 75 moves towards the discharge port under the drive of the drive ring 74, pushing the excess molten plastic towards the discharge port. The valve at the discharge port opens, and the excess molten plastic flows into the recovery bin 76 below through the discharge port, realizing the recovery of the excess molten plastic. The recovered molten plastic can be reused after processing. This not only reduces the waste of raw materials and lowers production costs, but also conforms to the concept of environmental protection. Moreover, the setting of the recovery component 7 makes the material use of the entire injection molding equipment more efficient, improving the economy and practicality of the equipment.

[0025] like Figure 3 and Figure 8 As shown in this embodiment, specifically, the stirring assembly 2 includes a stirring motor 21 and a stirring rod 22. The output end of the stirring motor 21 is connected to the stirring rod 22. Multiple sets of support rods 23 are installed on the stirring rod 22. The support rods 23 are equidistantly installed on the stirring rod 22. A slider 24 is installed on the other end of the support rod 23. The slider 24 is slidably installed inside the groove. The support rod 23 is provided with a bidirectional thread. A mixing assembly 8 is installed on the support rod 23 through the bidirectional thread. The mixing assembly 8 can assist in stirring the raw materials. The stirring assembly 2 can stir the plastic melt in the stirring tank 12, accelerating the melting of raw materials. In specific use, the stirring motor 21 is started, driving the stirring rod 22 to rotate. The multiple sets of support rods 23 on the stirring rod 22 rotate accordingly. Since the support rods 23 are equidistantly installed on the stirring rod 22, the uniformity of stirring can be ensured. The slider 24 on the support rod 23 slides in the groove, further enhancing the stability of the stirring process and preventing the stirring rod 22 from shaking or deviating when rotating. As the stirring rod 22 rotates, the bidirectional thread on the support rod 23 plays a role, driving the mixing assembly 8 to reciprocate along the support rod 23. During the reciprocating motion, the mixing assembly 8 continuously cuts, flips and mixes the plastic melt, so that various raw materials can fully contact and fuse. This design of the bidirectional thread driving the mixing assembly 8 greatly improves the efficiency and effect of stirring, and can stir the raw materials evenly in a shorter time, accelerating the melting speed of the raw materials. Meanwhile, the continuous stirring of the stirring component 2 can also prevent the plastic melt from stratifying or settling in the stirring tank 12, ensuring that the quality of the plastic melt remains stable. During the stirring process, the heating wire continuously heats the raw materials in the stirring tank 12, working in conjunction with the stirring component 2 to enable the raw materials to melt quickly and mix evenly at a suitable temperature. After being fully stirred and melted, the plastic melt enters the injection component 3 through the discharge port at the bottom of the stirring tank 12.

[0026] like Figure 8 As shown, in this embodiment, specifically, the mixing component 8 includes a mixing rod 81, which is connected to the support rod 23 by a bidirectional thread. The mixing rod 81 is provided with counterweights 82 at both ends, and the two sets of counterweights 82 have the same weight. When the mixing component 8 is in use, the mixing rod 81 reciprocates along the support rod 23 driven by the bidirectional thread. Since the mixing rod 81 is equipped with counterweights 82 of equal weight at both ends, the mixing rod 81 remains balanced during the movement, avoiding tilting or swaying, thus ensuring the stability and effectiveness of the mixing process. When the mixing rod 81 reciprocates, the counterweights 82 move with the mixing rod 81, increasing the inertia of the mixing rod 81, so that the mixing rod 81 can cut and flip the plastic melt more forcefully. The cutting action of the mixing rod 81 on the plastic melt can break up larger raw material clumps, making them easier to melt and mix.

[0027] like Figure 1 As shown in this embodiment, specifically, a control device 9 is installed on the side of the frame 11, and a control panel is adapted to be installed on the control device 9. The control device 9 is electrically connected to the entire injection molding equipment body 1, and the control panel is electrically connected to the control device 9. The control panel can indirectly control the entire injection molding equipment body 1. Because the control device 9 is electrically connected to the entire injection molding equipment body 1, and because the control panel is electrically connected to the control device 9, the operator can indirectly control the injection molding equipment body 1 through the control panel.

[0028] Working principle: When using this device, the mixing tank 12 is first used to mix the raw materials to ensure the uniformity of the materials. The mixing component 2 operates continuously in the mixing tank 12 to fully integrate different plastic particles or additives, preparing for the subsequent injection molding step. After mixing is completed, the extrusion component 6 is started, which drives the upper mold 62 to move downward and closely cooperate with the lower mold 13. The injection component 3 starts to work, which transports the mixed material between the lower mold 13 and the upper mold 62. The injection process needs to be precisely controlled to ensure that the amount of injected material meets the design requirements of the monitor shell. Then, the cooling component 5 will inject coolant into the cooling circuit between the upper mold 62 and the lower mold 13, so that the coolant can flow in the cooling circuit. During the flow of the coolant, it can continuously absorb the heat in the upper mold 62 and the lower mold 13, thereby accelerating the molding of the mold. After the material cools and solidifies in the mold, the extrusion component 6 moves the upper mold 62 upward, and then the pusher component 4 starts working, pushing the formed monitor shell out of the lower mold 13 for easy removal and further processing. Throughout the injection molding process, the device can evenly stir the material during use, preventing the plastic melt from clumping and causing the final product to fail to meet standards. Furthermore, the recycling component 7 can recover residual raw materials in the injection tube 32, preventing the plastic melt from solidifying in the injection tube 32, thereby saving raw material consumption.
