Technical field:

[0001] The utility model relates to the technical field of energy-saving and heat-insulating injection molding machines, in particular to an end-sealing cover of a vacuum heat-insulating sleeve. Background technology:

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. Injection molding is an important plastic processing method. In the process of injection molding, plastic particles are usually put into the barrel from the hopper, and the barrel is used to inject the solution into the inside of the fixed mold.

[0003] If the barrel of an injection molding machine is directly exposed without any energy-saving and heat-insulating measures, the following problems are generally encountered when the barrel of an injection molding machine is used: 1. The heat loss is large and the overall heating efficiency is low; 2. Even if it is not used temporarily, it cannot be stopped and needs to be heated continuously to maintain the temperature, which consumes a lot of energy overall; 3. The surrounding temperature is high and the operator is prone to feel uncomfortable. An energy-saving and heat-insulating device for the barrel of an injection molding machine is urgently needed. In order to solve the above problems and to be able to perform energy-saving, heat-insulating and heat-insulating measures on the barrel of an injection molding machine, most of the existing practices are to cover the outside of the barrel of the barrel of the injection molding machine with a cover such as Figure 1 Although the vacuum insulation sleeve shown can achieve certain energy-saving, heat-insulating and heat-insulating effects, the two ends of the vacuum insulation sleeve are not closed, and some heat will still leak out from the two ends of the vacuum insulation sleeve, thereby affecting the overall energy-saving, heat-insulating and heat-insulating effects; in addition, such as the Chinese utility model patent with application number 201720743586.X, which discloses a screw extruder insulation device, such as the Chinese utility model patent with application number 202321513486.X, which discloses an insulation structure of an injection molding machine heating cylinder, although these insulation devices can achieve certain energy-saving, heat-insulating and heat-insulating effects, the two ends are not closed and the energy-saving and heat-insulating effects are relatively general.

[0021] Explanation of the reference numerals: closed cover body 1, closed cover inner shell 11, closed cover outer shell 12, closed cover vacuum layer 13, closed cover plug-in end 14, sealing ring groove 141, closed cover closed end 15, closed part 151, closed cover sleeve hole 152, closed cover heat reflecting insulation layer 16, closed cover sealing ring 2. Specific implementation method:

[0022] The utility model will be further described below in conjunction with the accompanying drawings. Figure 2-3As shown, the utility model includes a closed cover body 1, the closed cover body 1 includes a closed cover inner shell 11, a closed cover outer shell 12, and a closed cover vacuum layer 13 arranged between the closed cover inner shell 11 and the closed cover outer shell 12, one end of the closed cover body 1 is a closed cover plug-in end 14 for matching with the vacuum insulation sleeve, the closed cover body 1 is inserted into the vacuum insulation sleeve through the closed cover plug-in end 14, the other end of the closed cover body 1 is a closed cover closed end 15, the closed cover closed end 15 is formed with a closed portion 151, and a closed cover sleeve hole 152 is formed at the middle position of the closed portion 151; by aligning the closed cover sleeve hole 152 of the utility model and sleeved on the barrel of the injection molding machine, the closed cover of the utility model is The plug-in end 14 is inserted into the vacuum insulation sleeve and one of the ends of the vacuum insulation sleeve is sealed. Similarly, the other end of the vacuum insulation sleeve is sealed. The vacuum layer 13 of the closed cover of the utility model can effectively reduce the heat conduction efficiency and reduce the heat loss to the surrounding environment. By using the utility model in conjunction with the vacuum insulation sleeve, the barrel of the injection molding machine can be better insulated and heat-insulated, and the heat loss can be better reduced and the heating efficiency can be improved. When not in use, the machine can be shut down and energy consumption can be reduced. The surrounding temperature of the barrel of the injection molding machine can be better reduced, and the working environment temperature of the operator can be prevented from being too high, and the operator can be more comfortable, which can further improve the energy-saving, heat preservation and insulation effects.

[0023] A closed cover heat reflecting insulation layer 16 is provided on the outer side of the closed cover inner shell 11. The closed cover heat reflecting insulation layer 16 is aluminum foil or an electroplating layer. The closed cover heat reflecting insulation layer 16 in this embodiment is aluminum foil, which can not only reflect infrared radiation heat well, but also has a relatively low overall cost and is easy to process. The closed cover heat reflecting insulation layer 16 can reflect infrared radiation heat and can further reduce heat loss to the surrounding environment, thereby further improving the overall heating efficiency and enhancing the heat preservation and heat insulation effects.

[0024] The vacuum degree of the closed cover vacuum layer 13 is preferably 9x10 -3 -1x10 -1 pa, the vacuum degree of the closed cover vacuum layer 13 is further preferably 8x10 -3 -1.8x10 -2 pa, can be used for heat preservation and insulation.

[0025] The thicker the closed cover vacuum layer 13 is, the better the thermal insulation effect is, but the more difficult it is to process and the higher the processing cost is. Taking all the above considerations into consideration, the thickness of the closed cover vacuum layer 13 is preferably 4-10 mm, which ensures the thermal insulation effect while ensuring the processing cost.

[0026] The utility model also includes a sealing ring 2 for a closed cover arranged at the joint position between the splicing end 14 of the closed cover and the vacuum insulation sleeve. By arranging the sealing ring 2 for a closed cover at the joint position between the splicing end 14 of the closed cover and the vacuum insulation sleeve, the sealing performance at the joint position between the splicing end 14 of the closed cover and the vacuum insulation sleeve can be improved, thereby better preventing heat from being lost at the joint position between the splicing end 14 of the closed cover and the vacuum insulation sleeve, and better ensuring the overall heat preservation and heat insulation effect.

[0027] The sealing ring groove 141 is formed at the plug-in end 14 of the closure cover, and the sealing ring 2 of the closure cover is sleeved on the sealing ring groove 141; by providing the sealing ring groove 141, not only is the sealing ring 2 of the closure cover easier to install, but the sealing ring 2 of the closure cover is also less likely to move, so that the connection position between the plug-in end 14 of the closure cover and the vacuum insulation sleeve can be better sealed, and heat can be better ensured not to be lost from the connection position between the plug-in end 14 of the closure cover and the vacuum insulation sleeve.

[0028] The depth at which the plug-in end 14 of the closed cover is inserted into the vacuum insulation sleeve is adjustable; by pushing and pulling the closed cover body 1, the depth at which the plug-in end 14 of the closed cover is inserted into the vacuum insulation sleeve can be adjusted, thereby being able to adjust the overall length of the utility model and the vacuum insulation sleeve, which is more flexible and practical, and can be better used in conjunction with injection molding machine barrels of different lengths.

[0029] The sealing cover inserting end 14 is a hollow cylindrical structure, which makes it easier to adjust the depth of the sealing cover inserting end 14 inserted into the vacuum insulation sleeve.

[0030] The closed end 15 of the closure cover is a hollow frustum-shaped structure. Since the barrel head of the injection molding machine barrel needs to be inserted into the gun pit during injection molding, the closed end 15 of the closure cover of the utility model near one end of the barrel head is designed to be a hollow frustum-shaped structure, which can keep the barrel head warm and insulate while making it easier to insert into the gun pit.

[0031] like Figure 4 As shown, an energy-saving insulation device for an injection molding machine barrel includes a vacuum insulation sleeve and two vacuum insulation sleeve end closing covers respectively arranged at both ends of the vacuum insulation sleeve. In this embodiment, the closing cover closing end 15 of the vacuum insulation sleeve end closing cover close to the barrel head is a hollow truncated cone structure, and the closing cover closing end 15 of the vacuum insulation sleeve end closing cover away from the barrel head is a hollow cylindrical structure.

[0032] Working principle:

[0033] By aligning the sealing cover sleeve hole 152 of the utility model and sleeved it on the injection molding machine barrel, inserting the sealing cover splicing end 14 of the utility model into the vacuum insulation sleeve and sealing one of the ends of the vacuum insulation sleeve, and similarly sealing the other end of the vacuum insulation sleeve, the sealing cover vacuum layer 13 of the utility model can effectively reduce the heat conduction efficiency and reduce the heat loss to the surrounding environment. By using the utility model in combination with the vacuum insulation sleeve, the injection molding machine barrel can be better insulated and heat-insulated, the heat loss can be better reduced, the heating efficiency can be improved, the machine can be shut down when not in use, the energy consumption can be reduced, the surrounding temperature of the injection molding machine barrel can be better reduced, the working environment temperature of the operator can be prevented from being too high, the operator can be more comfortable, and the energy-saving and heat-insulating effects can be further improved.

[0034] Of course, the above is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
