Technical Field
[0001] This utility model relates to the field of injection molding machine equipment technology, and more specifically, to a low-energy injection molding machine heat preservation device. Background Technology
[0002] In the field of injection molding equipment technology, energy consumption during injection molding machine operation has always been a key concern in the industry. Taking the injection molding machine with a heat insulation structure disclosed in application number CN202210044319.9 as an example, although it attempts to heat and insulate the plastic inside the barrel through a combination of structures such as an inner barrel tube, heat-conducting plate, heating device, outer barrel tube, insulation cotton, and protective sleeve, this insulation structure still has significant shortcomings. The insulation cotton used is a traditional insulation material with a relatively simple structure, which can only slow down heat transfer to a certain extent and is difficult to effectively prevent heat loss from the injection molding machine under high-temperature operating conditions. In actual injection molding production, the internal temperature of the injection molding machine often reaches 200℃-400℃. The insulation performance of traditional insulation cotton will decrease over time, causing a large amount of heat to be lost to the environment through the barrel and other parts of the injection molding machine.
[0003] This not only forces the heating device to operate continuously at high load to maintain the production temperature, resulting in a large consumption of electricity and increasing production costs for enterprises, but also affects the ambient temperature around the injection molding machine due to heat loss, causing discomfort to operators and reducing the molding quality and production efficiency of injection molded products. With the continuous rise in energy costs and increasingly stringent requirements for the production environment, there is an urgent need to develop new and efficient heat preservation devices for injection molding machines to solve the problems of serious heat loss and high energy consumption in traditional heat preservation structures. Utility Model Content
[0004] The purpose of this utility model is to provide a low-energy-consumption injection molding machine heat preservation device to solve the problems mentioned in the background art, such as the need for the heating device to operate continuously at high load to maintain the production temperature, resulting in a large consumption of electricity, increasing the production cost of enterprises, and affecting the ambient temperature around the injection molding machine due to heat loss, causing discomfort to the operators, and reducing the molding quality and production efficiency of injection molded products.
[0005] To achieve the above objectives, this utility model provides a low-energy injection molding machine heat preservation device, including a heat insulation cover, which is installed on the outside of the injection molding machine body. An adjustment component is installed on the top of the injection molding machine body, which can drive the heat insulation cover to expand and contract. The outer wall of the injection molding machine body is provided with a multi-layer heat preservation structure, which is formed by alternating layers of ceramic fiber layer and metal reflective plate layer.
[0006] This feature includes a heat shield covering the outside of the injection molding machine body, forming a thermal insulation barrier; an adjustment component is installed on the top of the injection molding machine body, and the expansion and contraction of the heat shield is controlled by mechanical transmission to adapt to different injection molding machine sizes; the multi-layer insulation structure uses alternating layers of ceramic fiber and metal reflector. The ceramic fiber layer uses its porous structure and low thermal conductivity to slow down heat conduction, while the metal reflector layer reflects heat through its high reflectivity. The two work together to reduce heat loss.
[0007] Preferably, a support component is installed on the top of the injection molding machine body, and the top inner wall of the heat insulation cover is supported and positioned by the support component.
[0008] This support component is installed on the top of the injection molding machine body to provide a support point for the heat insulation cover. By contacting the inner wall of the top of the heat insulation cover, it shares the weight of the heat insulation cover, maintains its stable shape, and ensures that the heat insulation cover will not deform or shift due to its own weight or external forces during the unfolding, shrinking and use process.
[0009] Preferably, the heat insulation cover has a hemispherical structure and includes a lifting plate. Several skeleton rods are radially installed on the outer side of the lifting plate, and adjacent skeleton rods are connected by an elastic heat insulation film. The lifting plate is driven to lift by an adjusting component.
[0010] This heat insulation cover is designed with a hemispherical structure. The lifting plate is raised and lowered under the drive of the adjustment components, which drives the outer frame rod to move. The elastic heat insulation film between the frame rods has a certain degree of elasticity and expands or contracts with the movement of the frame rods, thereby realizing the expansion and contraction of the heat insulation cover. When the hemispherical structure is expanded, it can better wrap the injection molding machine parts and provide a large area of coverage.
[0011] Preferably, the top of the support component is provided with several grooves, and each skeleton rod on the heat insulation cover is supported and positioned through the corresponding groove.
[0012] This feature includes a groove on the top of the support component that matches the shape of the heat insulation cover frame rod. The frame rod is embedded in the groove, and the heat insulation cover is positioned by mechanical limiting, restricting its horizontal movement while providing a certain amount of support in the vertical direction to ensure that the heat insulation cover is securely installed.
[0013] Preferably, the adjusting component includes a horizontal plate with a through threaded hole in the middle, and a screw is threaded into the threaded hole. The bottom end of the screw is rotatably connected to the lifting plate through a bearing.
[0014] The horizontal plate of the adjustment component serves as the basic load-bearing structure, and the threaded hole in the middle forms a threaded transmission pair with the screw. When the screw is rotated, according to the principle of threaded transmission, the screw moves up and down along the axis. The bottom end of the screw is rotatably connected to the lifting plate through a bearing, so that the rotational motion of the screw is converted into the linear lifting motion of the lifting plate, which in turn drives the heat insulation cover to unfold or retract.
[0015] Preferably, the bottom of both ends of the cross plate is equipped with support legs, and the bottom of both support legs is bolted to the top of the injection molding machine body.
[0016] The support legs at both ends of the horizontal plate serve to support and fix the horizontal plate. The bottom of the support legs are connected to the top of the injection molding machine body by bolts, so that the adjustment component is firmly installed on the injection molding machine. This ensures that the position of the adjustment component is fixed during the driving of the heat insulation cover, and provides a stable support foundation for the screw drive.
[0017] Preferably, the number of alternating layers of ceramic fiber layer and metal reflector layer is 3-7, and adjacent layers are bonded and fixed together with high-temperature resistant adhesive.
[0018] This design involves alternating layers of ceramic fiber and metal reflector in 3-7 layers to further enhance the heat insulation effect. High-temperature resistant adhesive is used to bond adjacent layers, ensuring a tight fit between the materials while adapting to the high-temperature working environment of the injection molding machine, preventing layer separation due to temperature changes, and maintaining the stability of the multi-layer structure.
[0019] Preferably, the outer side of the multi-layer insulation structure is also provided with a far-infrared reflective layer and a vacuum insulation layer. The far-infrared reflective layer is located between the multi-layer insulation structure and the vacuum insulation layer to reduce heat loss in the form of far-infrared radiation.
[0020] This feature adds a far-infrared reflective layer and a vacuum insulation layer to the outside of the multi-layer insulation structure. The far-infrared reflective layer uses the high reflectivity of its special material to far-infrared radiation to reflect the far-infrared heat emitted by the injection molding machine back into the equipment. The vacuum insulation layer creates a vacuum environment, which almost eliminates air convection and greatly reduces heat conduction and convection loss.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] This low-energy injection molding machine insulation device achieves significant technical benefits through the synergistic design of a multi-layer insulation structure and an adjustable heat insulation cover. In the multi-layer insulation structure, ceramic fiber layers and metal reflector layers are alternately stacked, along with a far-infrared reflective layer and a vacuum insulation layer, forming a highly efficient heat insulation system. Compared to traditional insulation cotton structures, this significantly reduces heat loss through conduction, convection, and radiation, lowers the operating frequency of the heating device, and reduces injection molding machine energy consumption by 30%-40%, significantly saving production costs for enterprises.
[0023] The adjusting components drive the heat insulation cover to expand and contract, working in conjunction with the supporting components and rotating mechanism to quickly adapt to injection molding machines of different sizes. This ensures the insulation device always tightly covers critical injection molding areas, enhancing the flexibility and versatility of the equipment. The heat insulation cover features a hemispherical structure with a frame rod and elastic insulation film design, combined with a sealing airbag. This ensures excellent insulation performance while enhancing the device's sealing, preventing heat loss through gaps and further improving thermal efficiency. Simultaneously, the device optimizes the user experience with features such as the rotating handle at the top of the screw and the limiting ring on the horizontal plate, making the heat insulation cover adjustment process more stable and convenient. This effectively improves production efficiency, enhances the workshop production environment, and guarantees the molding quality and stability of injection-molded products.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] This utility model provides a low-energy-consumption injection molding machine heat preservation device, such as... Figure 1 , Figure 2 As shown, it includes a heat insulation cover 2 with an opening at the bottom. The heat insulation cover 2 covers the outside of the injection molding machine body 1. An adjustment component 3 is installed on the top of the injection molding machine body 1. The adjustment component 3 can drive the heat insulation cover 2 to expand and contract. The outer wall of the injection molding machine body 1 is provided with a multi-layer heat insulation structure. The multi-layer heat insulation structure is formed by alternating layers of ceramic fiber layer 11 and metal reflector layer 12.
[0032] In use, the heat insulation cover 2 is placed over the outside of the injection molding machine body 1, forming a thermal insulation barrier. The adjustment component 3 is installed on the top of the injection molding machine body 1, and controls the expansion and contraction of the heat insulation cover 2 through mechanical transmission to adapt to different injection molding machine sizes. The multi-layer insulation structure uses alternating layers of ceramic fiber layer 11 and metal reflective plate layer 12. The ceramic fiber layer 11 utilizes its porous structure and low thermal conductivity to slow down heat conduction, while the metal reflective plate layer 12 reflects heat through its high reflectivity. The two work together to reduce heat loss. The combination of the heat insulation cover 2 and the multi-layer insulation structure effectively reduces the heat dissipation of the injection molding machine to the outside. The adjustment component 3 controls the flexible adjustment of the coverage area of the heat insulation cover 2, enabling the insulation device to adapt to different production needs, improving equipment versatility and insulation effect, and reducing energy consumption.
[0033] In this embodiment, as Figure 2 As shown, a support component 4 is installed on the top of the injection molding machine body 1, and the inner wall of the top of the heat insulation cover 2 is supported and positioned by the support component 4. The support component 4 is an annular support plate.
[0034] The support component 4 is installed on the top of the injection molding machine body 1 to provide a support point for the heat insulation cover 2. By contacting the inner wall of the top of the heat insulation cover 2, it shares the weight of the heat insulation cover 2 and maintains its stable shape. This ensures that the heat insulation cover 2 will not deform or shift due to its own weight or external forces during the unfolding, shrinking and use process, thereby enhancing the structural stability of the heat insulation cover 2 and ensuring that the positional relationship between the heat insulation cover 2 and the injection molding machine body 1 is fixed. This allows the heat insulation device to continuously and stably perform its heat insulation function and avoids a decrease in heat insulation performance due to shaking or deformation of the heat insulation cover 2.
[0035] Specifically, such as Figure 3As shown, the heat insulation cover 2 has a hemispherical structure and includes a lifting plate 22. Several skeleton rods 21 are installed radially on the outer side of the lifting plate 22. Adjacent skeleton rods 21 are connected by an elastic heat insulation film 23. The lifting plate 22 is driven to lift by the adjusting component 3.
[0036] The heat insulation cover 2 is designed with a hemispherical structure. The lifting plate 22 is raised and lowered under the drive of the adjusting component 3, which drives the outer frame rod 21 to move. The elastic heat insulation film 23 between the frame rods 21 has a certain degree of elasticity and expands or contracts with the movement of the frame rods 21, thereby realizing the expansion and contraction of the heat insulation cover 2. When expanded, the hemispherical structure can better wrap the injection molding machine parts, providing a large area of coverage. The hemispherical structure, combined with the elastic heat insulation film 23 and the frame rods 21, allows the heat insulation cover 2 to flexibly change the coverage area to adapt to injection molding machines of different sizes. The elastic heat insulation film 23 ensures that the heat insulation cover 2 maintains good heat insulation performance during deformation, avoids heat leakage due to structural changes, and improves the practicality and heat preservation efficiency of the heat preservation device.
[0037] Furthermore, the top of the support component 4 is provided with several grooves, and each skeleton rod 21 on the heat insulation cover 2 is supported and positioned through the corresponding groove.
[0038] The groove on the top of the support component 4 is adapted to the shape of the frame rod 21 of the heat insulation cover 2. The frame rod 21 is hinged and embedded in the groove, and the heat insulation cover 2 is positioned by mechanical limiting, restricting the horizontal movement of the heat insulation cover 2, while providing a certain support force in the vertical direction, ensuring that the heat insulation cover 2 is stably installed and accurately positioned, preventing it from shifting or rotating during use, further improving the stability and reliability of the heat insulation cover 2 installation, and ensuring that the heat insulation device always maintains a good heat insulation state during the operation of the injection molding machine.
[0039] Furthermore, such as Figure 4 As shown, the adjusting component 3 includes a horizontal plate 31, with a through threaded hole in the middle of the horizontal plate 31, and a screw 33 is threadedly connected inside the threaded hole. The bottom end of the screw 33 is rotatably connected to the lifting plate 22 through a bearing.
[0040] The horizontal plate 31 of the adjusting component 3 serves as the basic load-bearing structure. The threaded hole in the middle forms a threaded transmission pair with the screw 33. When the screw 33 is rotated, according to the principle of threaded transmission, the screw 33 moves up and down along the axial direction. The bottom end of the screw 33 is rotatably connected to the lifting plate 22 through a bearing, so that the rotational motion of the screw 33 is converted into the linear lifting motion of the lifting plate 22, thereby driving the heat insulation cover 2 to unfold or retract. This provides a simple and reliable driving method. The operator can rotate the screw 33 manually or with auxiliary tools to precisely control the lifting of the heat insulation cover 2, realize flexible adjustment of the coverage area of the heat insulation cover 2, and is convenient to operate, highly accurate in adjustment, and easy to adapt to different production scenarios.
[0041] Furthermore, such as Figure 4 As shown, support legs 32 are installed at the bottom of both ends of the horizontal plate 31, and the bottom of both support legs 32 are bolted to the top of the injection molding machine body 1. The heat insulation cover 2 has holes for the support legs 32 to slide through (not shown in the attached figure).
[0042] The support legs 32 at both ends of the horizontal plate 31 serve to support and fix the horizontal plate 31. The bottom of the support legs 32 are connected to the top of the injection molding machine body 1 by bolts, so that the adjusting component 3 is firmly installed on the injection molding machine. This ensures that the adjusting component 3 is fixed in position during the driving of the heat insulation cover 2, provides a stable support foundation for the screw 33 transmission, ensures that the adjusting component 3 is firmly installed, enhances the overall stability of the adjusting component 3, and avoids the adjustment accuracy and normal operation of the heat insulation cover 2 due to the shaking or displacement of the adjusting component 3 when adjusting the heat insulation cover 2, thus ensuring the reliability of the heat insulation device's adjustment function.
[0043] Furthermore, such as Figure 2 As shown, the number of alternating layers of ceramic fiber layer 11 and metal reflective plate layer 12 is 3-7, and adjacent layers are bonded and fixed together with high-temperature resistant adhesive. The ceramic fiber layer 11 and metal reflective plate layer 12 are grouped together, and multiple groups of ceramic fiber layer 11 and metal reflective plate layer 12 are bonded and fixed together with high-temperature resistant adhesive.
[0044] Ceramic fiber layer 11 and metal reflector layer 12 are alternately stacked in 3-7 layers, further enhancing the heat insulation effect through multi-layer stacking. High-temperature resistant adhesive bonds adjacent layers, ensuring a tight fit while adapting to the high-temperature working environment of the injection molding machine, preventing interlayer separation due to temperature changes, and maintaining the stability of the multi-layer structure. The alternating multi-layer structure significantly improves thermal insulation performance, effectively blocking heat conduction and radiation, and reducing heat loss; the high-temperature resistant adhesive ensures long-term stable operation of the multi-layer structure at high temperatures, extending the service life of the insulation device and reducing maintenance costs.
[0045] Furthermore, such as Figure 2 As shown, a far-infrared reflective layer 13 and a vacuum insulation layer 14 are also provided on the outside of the multi-layer insulation structure. The far-infrared reflective layer 13 is located between the multi-layer insulation structure and the vacuum insulation layer 14, and is used to reduce the loss of heat in the form of far-infrared radiation.
[0046] An infrared reflective layer 13 and a vacuum insulation layer 14 are added to the outside of the multi-layer insulation structure. The infrared reflective layer 13 uses the high reflectivity of its special material to far-infrared radiation to reflect the far-infrared heat emitted by the injection molding machine back into the equipment. The vacuum insulation layer 14 creates a vacuum environment, which almost eliminates air convection and greatly reduces heat conduction and convection loss. It comprehensively blocks heat loss from the three heat transfer paths of radiation, conduction and convection, further improving the insulation performance of the insulation device, so that the heat inside the injection molding machine can be effectively maintained, significantly reducing energy consumption and improving energy utilization efficiency.
[0047] In use, the low-energy injection molding machine insulation device of this utility model first fixes the support leg 32 to the top of the injection molding machine body 1 with bolts, thereby securely installing the horizontal plate 31. Then, screws the screw 33 into the threaded hole in the middle of the horizontal plate 31, and connects the bottom end of the screw 33 to the lifting plate 22 through a bearing. Subsequently, the lifting plate 22 with the skeleton rod 21 and the elastic heat insulation film 23 is assembled with the screw 33, so that the skeleton rod 21 is embedded into the groove at the top of the support component 4, completing the positioning and installation of the heat insulation cover 2. At the same time, the multi-layer heat insulation structure is bonded and fixed with high-temperature resistant adhesive and installed on the outer wall of the injection molding machine body 1.
[0048] Injection Molding Machine Adaptation and Heat Insulation Cover Adjustment: When changing to an injection molding machine of a different size, the operator rotates the screw 33. The screw 33 moves axially under the action of the threaded transmission, causing the lifting plate 22 to rise or fall. The movement of the lifting plate 22 causes the skeleton rod 21 to move accordingly, and the elastic heat insulation film 23 to extend or contract, thereby enabling the heat insulation cover 2 to expand or contract to adapt to the current injection molding machine size and ensure that the heat insulation cover 2 can tightly cover the critical parts of the injection molding machine.
[0049] Thermal insulation operation: After the injection molding machine starts working, high temperatures are generated inside. The multi-layer insulation structure begins to function. The ceramic fiber layer 11 hinders heat conduction, the metal reflector layer 12 reflects heat, the far-infrared reflector layer 13 reflects far-infrared radiant heat back into the equipment, and the vacuum insulation layer 14 prevents heat loss through conduction and convection, effectively reducing heat dissipation to the external environment. At the same time, the heat insulation cover 2, in a suitable covering state, works in conjunction with the multi-layer insulation structure to further prevent heat escape, maintain a stable internal temperature of the injection molding machine, reduce the operating frequency and duration of the heating device, and lower energy consumption.
[0050] Continuous monitoring and adjustment: During the operation of the injection molding machine, the operator can flexibly adjust the coverage area of the heat insulation cover 2 by rotating the screw 33 again according to the actual production situation and changes in the injection molding machine, so as to ensure that the heat insulation device is always in the best working state and continuously and efficiently achieve the heat insulation and energy saving effect.
[0051] Finally, it should be noted that the electronic components in the injection molding machine body 1 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.
