Description

Technical field:

[0001] The utility model relates to the technical field of energy-saving and heat-insulating injection molding machines, in particular to a modular 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 large amount 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 on the barrel of an injection molding machine, most of the existing practices are to cover the barrel of the injection molding machine with an insulation sleeve, 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 barrel, although it can achieve the effects of energy-saving, heat-insulating and heat-insulating, the existing insulation sleeves are mostly one-piece structures with a single length, which cannot well meet the use of injection molding machine barrels of different lengths. Utility model content:

[0004] The purpose of the utility model is to provide a modular vacuum insulation sleeve to address the deficiencies in the prior art. The modular vacuum insulation sleeve can not only well insulate and heat-insulate the barrel of an injection molding machine, but also reduce heat loss and improve heating efficiency. The machine can be shut down when not in use to reduce energy consumption. The peripheral temperature of the barrel of the injection molding machine can be reduced to prevent the operator's working environment temperature from being too high, making the operator more comfortable, and can well meet the use of injection molding machine barrels of different lengths and models, with greater flexibility.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a modular vacuum insulation sleeve, including a plurality of insulation sleeve units, each of which is arranged side by side in sequence along the length direction of the barrel; a plurality of tight-connecting ears are evenly distributed along the circumferential direction at both ends of the outer sides of the insulation sleeve units, and each tight-connecting ear located on the front end of the insulation sleeve unit is connected to the corresponding tight-connecting ear located on the rear end of the adjacent insulation sleeve unit through a bolt assembly.

[0006] A further improvement to the above solution is that the insulation sleeve unit includes an insulation sleeve inner shell, an insulation sleeve outer shell, and an insulation sleeve vacuum layer arranged between the insulation sleeve inner shell and the insulation sleeve outer shell.

[0007] A further improvement to the above scheme is that a heat-reflecting insulation layer of the heat-reflecting insulation layer is provided on the outer side of the inner shell of the heat-reflecting insulation layer, and the heat-reflecting insulation layer of the heat-reflecting insulation layer is an aluminum foil or an electroplating layer.

[0008] A further improvement to the above scheme is that the vacuum degree of the vacuum layer of the insulation sleeve is 9x10-3-1x10-1Pa.

[0009] A further improvement to the above scheme is that the vacuum degree of the vacuum layer of the insulation sleeve is 8x10-3-1.8x10-2Pa.

[0010] A further improvement to the above solution is that the thickness of the vacuum layer of the insulation sleeve is 4-10 mm.

[0011] A further improvement to the above solution is that the outer shell of the insulation sleeve is formed with a plurality of annular reinforcing ribs.

[0012] A further improvement to the above solution is that the diameter of the thermal insulation sleeve unit is 185-211 mm.

[0013] A further improvement to the above solution is that the length of the thermal insulation sleeve unit is 198-218 mm.

[0014] A further improvement to the above scheme is that insulation sleeve sealing rings are respectively provided at the connecting positions of each of the insulation sleeve units.

[0015] The beneficial effects of the utility model are as follows: the modular vacuum insulation cover provided by the utility model comprises a plurality of insulation cover units, each of which is arranged side by side in sequence along the length direction of the barrel; a plurality of tight connection ears are evenly arranged at both ends of the outer sides of the insulation cover units along the circumferential direction, and each of the tight connection ears located on the front end of the insulation cover unit is connected to the corresponding tight connection ears located on the rear end of the adjacent insulation cover unit through a bolt assembly;

[0016] Compared with the thermal insulation sleeve of one-piece structure and single length, which can only be applied to the barrels of some injection molding machines, it is necessary to re-open the mold and design the thermal insulation sleeve when it is applied to the barrels of other injection molding machines of different lengths. The utility model is composed of a plurality of thermal insulation sleeve units, and the corresponding number of thermal insulation sleeve units can be selected according to the specific use requirements to form vacuum thermal insulation sleeves of different lengths. It can not only well insulate and heat-insulate the barrel of the injection molding machine, but also reduce heat loss and improve heating efficiency. It can also be shut down and reduce energy consumption when not in use temporarily, and can reduce the peripheral temperature of the barrel of the injection molding machine, so as to prevent the working environment temperature of the operator from being too high and make the operator more comfortable, and it can well meet the use of barrels of injection molding machines of different lengths and has greater flexibility. The cooperation of the close connection ears and the bolt assembly on the two thermal insulation sleeve units can make the connection between the two thermal insulation sleeve units more stable and not easy to fall off.

Specific implementation method:

[0022] The utility model will be further described below in conjunction with the accompanying drawings. Figure 1-4As shown, the utility model includes a plurality of insulation sleeve units 1, the insulation sleeve units 1 include an insulation sleeve inner shell 11, an insulation sleeve outer shell 12, and an insulation sleeve vacuum layer 13 arranged between the insulation sleeve inner shell 11 and the insulation sleeve outer shell 12, and the insulation sleeve units 1 are arranged side by side in sequence along the length direction of the barrel; the outer ends of the insulation sleeve units 1 are respectively provided with a plurality of tight connection ears 14 evenly distributed along the circumferential direction, and the tight connection ears 14 located on the front end of the insulation sleeve unit 1 are respectively connected with the corresponding tight connection ears 14 located on the rear end of the adjacent insulation sleeve unit 1 through a bolt assembly 2; compared with the insulation sleeve with an integrated structure and a single length, it can only be applied to injection molding machine barrels of some length models, and it is not applicable to injection molding machines of other different length models. The utility model is composed of a plurality of insulation sleeve units 1, and the corresponding number of insulation sleeve units 1 can be selected according to the specific use requirements to form vacuum insulation sleeves of different lengths, which can not only well insulate and heat-insulate the barrel of the injection molding machine, but also reduce heat loss and improve heating efficiency. When not in use, the machine can be shut down to reduce energy consumption, and the peripheral temperature of the barrel of the injection molding machine can be reduced, which can prevent the operating environment temperature of the operator from being too high and make the operator more comfortable. Moreover, it can well meet the use of injection molding machine barrels of different lengths and models, and has greater flexibility. The cooperation of the tight connection ears 14 and the bolt assembly 2 on the two insulation sleeve units 1 can make the connection between the two insulation sleeve units 1 more stable and less likely to fall off.

[0023] An insulation sleeve heat reflecting insulation layer 15 is provided on the outer side of the insulation sleeve inner shell 11. The insulation sleeve heat reflecting insulation layer 15 is aluminum foil or an electroplating layer. The insulation sleeve heat reflecting insulation layer 15 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 insulation sleeve heat reflecting insulation layer 15 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 thermal insulation and heat preservation effects.

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

[0025] Since the barrel sizes of different types of injection molding machine barrels are different, the diameter of the thermal insulation sleeve unit 1 of the utility model is 185-211 mm, which can be preferably applied to the barrels of injection molding machines of 120-300 tons.

[0026] If the length of a single insulation sleeve unit 1 is too short, a large number of insulation sleeve units 1 are required for splicing, which not only makes assembly more troublesome, but also causes a large number of overall splicing gaps, affecting the overall insulation effect; if the length of a single insulation sleeve unit 1 is too long, it is not only inconvenient to control the overall length, but also makes the insulation sleeve unit 1 difficult to process and has a high processing cost; based on the above considerations, the length of the insulation sleeve unit 1 of the utility model is preferably 198-218mm, which can better meet the actual application scenarios.

[0027] The thicker the insulation sleeve vacuum layer 13 is, the better the 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 insulation sleeve vacuum layer 13 is preferably 4-10 mm, which ensures the insulation effect while ensuring the processing cost.

[0028] An insulation sleeve sealing ring 3 is respectively provided at the connecting position of each of the insulation sleeve units 1; by respectively providing the insulation sleeve sealing ring 3 at the connecting position of each of the insulation sleeve units 1, the sealing performance at the connecting position of each of the insulation sleeve units 1 can be improved, thereby better preventing heat from being lost from the connecting position of each of the insulation sleeve units 1, and better ensuring the insulation and heat insulation effect of the vacuum insulation sleeve; in addition, through the cooperation of the tight connection ears 14 and the bolt assembly 2 on the two insulation sleeve units 1, the insulation sleeve sealing ring 3 can also be tightened. Compared with simply setting the insulation sleeve sealing ring 3 at the connecting position of the insulation sleeve unit 1, the tightened insulation sleeve sealing ring 3 can better and more fully seal the gap at the connecting position of the insulation sleeve unit 1, thereby better ensuring that heat will not be lost from the connecting position of each of the insulation sleeve units 1, and better ensuring the insulation and heat insulation effect of the vacuum insulation sleeve.

[0029] The outer shell 12 of the heat preservation sleeve is formed with a plurality of annular reinforcing ribs 121 . The annular reinforcing ribs 121 can improve the structural strength of the outer shell 12 of the heat preservation sleeve, thereby preventing deformation during vacuuming.

[0030] Working principle:

[0031] According to the length of the injection molding machine barrel, a corresponding number of insulation sleeve units 1 are selected, and the insulation sleeve units 1 are arranged side by side in sequence along the length direction of the barrel. The insulation sleeve units 1 are connected as a whole through the cooperation of the tight connection ears 14 and the bolt assembly 2 on each insulation sleeve unit 1; compared with the insulation sleeve with an integrated structure and a single length, which can only be applied to injection molding machine barrels of certain length models, it is necessary to re-open the mold and design the insulation sleeve when it is applied to the other injection molding machine barrels of different length models. The utility model is composed of a plurality of insulation sleeve units 1, and a corresponding number of insulation sleeve units 1 can be selected according to specific use requirements. The sleeve unit 1 is composed of vacuum insulation sleeves of different lengths, which can not only well insulate and heat-insulate the barrel of the injection molding machine, but also reduce heat loss and improve heating efficiency. It can be shut down when not in use to reduce energy consumption. It can also reduce the ambient temperature of the barrel of the injection molding machine, prevent the operator's working environment temperature from being too high, and make the operator more comfortable. It can also well meet the use of injection molding machine barrels of different lengths and models, and has greater flexibility. The cooperation of the tight connection ears 14 and the bolt assembly 2 on the two insulation sleeve units 1 can make the connection between the two insulation sleeve units 1 more stable and less likely to fall off.

[0032] 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.
