Abstract
Description
Technical Field
[0001] The utility model belongs to the field of injection molding machines and relates to the oil tank technology of injection molding machines, in particular to an oil tank structure of an injection molding machine and an oil tank mounting frame. Background Art
[0002] Injection molding machines, also known as injection molding machines or injection machines, are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. They are available in vertical, horizontal, and all-electric models. They heat the plastic and apply high pressure to the molten plastic, ejecting it and filling the mold cavity.
[0003] During the operation of commercial injection molding machines, hydraulic oil serves as the working medium of the hydraulic system, driving the entire machine. After the hydraulic oil circulates through the machine and returns to the oil tank, the temperature of the hydraulic oil will increase. Therefore, a circulating cooling pipe is usually installed internally to circulate and cool the hydraulic oil. However, this setting has certain drawbacks: as shown above, although the circulating cooling pipe can cool the hydraulic oil, when the oil pump is operated multiple times in a short period of time, the heated hydraulic oil may not be able to fully contact the circulating cooling pipe to dissipate heat and be sucked into the external oil pump, which in turn affects the performance of the machine and product quality.
[0004] Therefore, a fuel tank structure for an injection molding machine and a fuel tank mounting frame are needed to solve the above problems. Utility Model Content

[0035] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] Example 1
[0037] See also Figures 1 to 3 As shown, an embodiment of the first aspect of the present invention provides an injection molding machine oil tank structure, including a tank body 1 and an air-cooling pipe assembly 2.
[0038] An oil return area 11 and an oil outlet area 12 are formed in the box body 1 to respectively connect to an oil return pipeline and an oil outlet pipeline (ie, an oil pump).
[0039] The air-cooling pipe assembly 2 includes a main body 21 and a circulation pipe 22 .
[0040] Specifically, the main body 21 is arranged in the box body 1, and has an air inlet channel and an air exhaust channel connected to the outside to form a circulation channel. Therefore, by injecting cold air into the air inlet channel, the hydraulic oil can be cooled.
[0041] It should be noted that the main body 21 divides the oil return area 11 into a first oil return area 111 and a second oil return area 112, which are interconnected, and the second oil return area 112 is connected to the oil outlet area 12. Therefore, when the hydraulic oil enters the first oil return area 111 and the oil pump is running, the hydraulic oil must pass through the first oil return area 111, the second oil return area 112, and the oil outlet area 12 in sequence before it can be sucked up by the oil pump. Therefore, by extending the contact path between the hydraulic oil and the air-cooling pipe assembly 2, the cooling time of the hydraulic oil is correspondingly extended, thereby improving the cooling effect of the hydraulic oil. This can prevent the hydraulic oil from being sucked into the oil return area 11 by the oil pump right after entering the machine, ensuring the production quality of subsequent products and correspondingly extending the service life of the machine.
[0042] In this embodiment, the circulation pipe 22 is arranged in a curved and folded shape within the oil outlet area 12, and its two ends are connected to the air inlet channel and the exhaust channel respectively. By arranging the circulation pipe 22 in a curved and folded shape, the contact area with the hydraulic oil is increased, thereby improving the cooling effect.
[0043] Among them, the box body 1 is provided with an oil return conduit 13 connected to the external oil return pipeline, and one end of the oil return conduit 13 extends into the first oil return area 111 so that the hydraulic oil can enter the first oil return area 111 after being output by the machine.
[0044] The box body 1 is provided with an oil extraction port 14 connected to an external oil extraction pipeline, and the oil extraction port 14 is connected to the oil outlet area 12 .
[0045] The device is provided with an air-cooling pipe assembly 2 including a main body 21 and a circulation pipe 22, and the main body 21 separates the return oil area 11 into a first oil return area 111 and a second oil return area 112 that are interconnected, and the second oil return area 112 is connected to the oil outlet area 12, and the return oil conduit 13 is extended to the first oil return area 111, so that when the hydraulic oil is input into the interior of the box body 1 through the return oil conduit 13, it needs to pass through the first oil return area 111 and the second oil return area 112 in sequence before entering the oil outlet area 12, thereby effectively extending the path that the hydraulic oil needs to pass through when being extracted by the oil pump, thereby correspondingly extending the contact time between the hydraulic oil and the air-cooling pipe assembly 2, thereby improving the cooling effect of the hydraulic oil, and avoiding the situation where the hydraulic oil cannot be fully cooled and is sucked into the oil pump for operation, thereby improving product quality and extending the service life of the machine.
[0046] In this embodiment, the main body 21 includes a U-shaped baffle 211 and a connecting pipe 212 .
[0047] The U-shaped baffle 211 is fixedly mounted on the inner wall of the box body 1 , and the U-shaped baffle 211 is configured as a hollow structure to form an air intake channel and an air outlet channel.
[0048] Furthermore, the outer wall of the box body 1 is provided with a first opening 15 and a second opening 16 .
[0049] The first opening 15 is connected to a side wall of the U-shaped baffle 211 to form the air exhaust channel.
[0050] One end of the communication pipe 212 is communicated with the other side wall of the U-shaped baffle 211 , and the other end extends to communicate with the second opening 16 to form the air inlet channel.
[0051] It should be noted that gaps are reserved between both ends of the U-shaped baffle 211 and the inner wall of the box body 1 , and between the connecting pipe 212 and the inner wall of the box body 1 , so as to form a channel connecting the first oil return area 111 and the second oil return area 112 .
[0052] In order to facilitate the air supply and exhaust operations of the external components, the first opening 15 and the second opening 16 are located in the same vertical plane.
[0053] In other embodiments, a mounting hole 17 for connecting an external temperature monitoring sensor (not shown in the figure) is provided on one side of the box body 1 to monitor the temperature of the box body 1 .
[0054] In other embodiments, the temperature monitoring sensor is connected to the external wind conveying equipment 5 signal through the smart terminal, and the smart terminal is equipped with a built-in PID control system, so that the wind intensity provided by the wind conveying equipment 5 can be adaptively adjusted according to the external temperature of the box 1 to achieve the best energy efficiency ratio.
[0055] Furthermore, this configuration can effectively prevent the fuel tank from being overcooled or undercooled.
[0056] Example 2
[0057] like Figure 4 As shown, this embodiment further proposes an oil tank mounting frame based on the first embodiment. Specifically, the oil tank mounting frame includes an upper panel 3, a lower panel 4, a wind conveying device 5 and the injection molding machine oil tank structure as described in the first embodiment.
[0058] The upper panel 3 and the lower panel 4 are connected by a connector to enclose and form a cooling chamber that matches the oil tank structure of the injection molding machine. Auxiliary heat dissipation can be achieved by arranging a blowing component outside the frame.
[0059] The wind conveying equipment 5 is installed in the cooling chamber and is connected to the air inlet channel to provide wind power to enhance the cooling effect of the hydraulic oil.
[0060] Specifically, the wind conveying equipment 5 is configured as an air conditioner.
[0061] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
