The invention provides a short-range extruder with a water cooling mechanism, and aims to solve the problem that a throat pipe is cooled through a cooling pipe, and the heat dissipation effect is poor.

Referring to fig. 1 and 2, the short-range extruder with a water cooling mechanism provided by the invention comprises a front seat 1, a base 2 and a cover plate 5, wherein the base 2 covers the front seat 1 and forms an installation cavity 27, a throat pipe 8 positioned in the installation cavity 27 is fixedly connected to the base 2, a water passing groove 21 corresponding to the throat pipe 8 is formed in one side of the base 2 away from the front seat 1, a partition plate 22 is fixed in the water passing groove 21, one end of the partition plate 22 is fixed to the wall of the water passing groove 21, the other end of the partition plate 22 is arranged at an interval with the wall of the water passing groove 21, a water inlet 23 and a water outlet 24 connected to the water passing groove 21 are formed in the base 2, and the water inlet 23 and the water outlet 24 are respectively positioned on two sides of the partition plate 22; the cover plate 5 is used to cover the water tank 21.

In the embodiment, the short-range extruder usually generates a large amount of heat in the working process, and in order to ensure that the short-range extruder does not influence the working of the machine due to overheating, heat dissipation treatment is usually performed, and the heat dissipation treatment is particularly important for the heat dissipation work of the throat 8 of the discharge pipe. Base 2 adopts the metal material preparation that the heat transfer effect is good, for example can be stainless steel base 2, aluminum alloy base 2 etc, choke 8 inlays to be established on base 2, and be located installation cavity 27, basin 21 has been seted up to the opposite side that corresponds choke 8 on base 2, it is fixed with division board 22 to cross the basin 21 internal, division board 22's one end is fixed with the cell wall of crossing basin 21, division board 22's the other end and the cell wall interval setting of crossing basin 21, seted up water inlet 23 and the delivery port 24 that even passes through basin 21 on base 2, water inlet 23 and delivery port 24 are located division board 22's both sides respectively, and water inlet 23 and delivery port 24 do not clear and definite limited, water inlet 23 can also can go out with intaking, the direction of unrestricted rivers. Meanwhile, the water inlet 23 and the water outlet 24 can be externally connected with pipelines, so that water inlet and outlet work is facilitated. A cover plate 5 is also arranged to cover the water passing tank 21, so that the cover plate 5 and the water passing tank 21 form a closed chamber.

During the concrete implementation, with water inlet 23 and the external pipeline of delivery port 24, carry out the water injection to the pipeline of water inlet 23, the cooling water flows out by delivery port 24 after passing through basin 21, because division board 22 blocks, it forms the arc wall to cross basin 21, the cooling water shifts the heat that 8 transmit the base 2 of choke to the circulation in-process of crossing basin 21, thereby dispel the heat to choke 8 and even whole short range extruder, because choke 8 inlays to establish on base 2, the heat on 8 of choke can be quick is absorbed and transmit the cooling water by base 2 and is discharged by the cooling water, thereby the radiating effect of short range extruder has been improved.

Further, the side edges of the partition plate 22 are arranged in an arc shape. In this embodiment, set up division plate 22 into the arc, can reduce the resistance of rivers in-process, simultaneously, because division plate 22's one end is fixed with the cell wall of crossing basin 21, division plate 22's the other end and the cell wall interval of crossing basin 21 set up for division plate 22 blocks the cooling water when the cooling water flows into basin 21, prolongs the dwell time of cooling water in crossing basin 21, makes to absorb more heats.

Referring to fig. 3, a plurality of buffer zones 3 are provided in the water passing groove 21 in parallel to the side edges of the partition plate 22 at intervals. Specifically, buffer zone 3 adopts the stainless steel preparation that can transfer heat, and buffer zone 3 sets up the rivers of strengthening and base 2's area of contact, has improved the radiating efficiency, and buffer zone 3 plays to slow down the flow to rivers simultaneously and blocks the effect that the cooling water formed the backward flow, and the cooling water of backward flow part can carry out the secondary to the heat and absorb, further improves radiating effect.

Further, the buffer belt 3 includes a plurality of buffer plates 31 arranged at intervals. Specifically, set up the buffer board 31 that buffer zone 3 set up to a plurality of intervals and set up, further increase rivers and base 2 area of contact, the buffer board 31 of the turn position setting in crossing basin 21 again simultaneously can play and block the effect that the rivers formed the backward flow to slow down the velocity of water, make the total heat that the cooling water that flows through basin 21 was taken away increase.

Further, a gasket 4 is provided outside the water passing groove 21, and the gasket 4 is interposed between the base 2 and the cover 5. Specifically, the packing 4 may seal a chamber formed by the water passing groove 21 and the cover plate 5, and water placed in the water passing groove 21 may leak out. In this embodiment, the seal ring 4 may be a rubber seal ring 4, or may be a silicone seal ring 4.

Further, a placing groove 26 for placing the sealing ring 4 is opened on the base 2. Specifically, set up on base 2 and be used for placing sealing washer 4 standing groove 26 for sealing washer 4 is installed more stably, places sealing washer 4 and moves the sealed effect of influence because not pressing from both sides tightly when base 2 and apron 5 assemble. Specifically, the placing groove 26 and the sealing ring 4 need to be matched, so that the sealing ring 4 is convenient to mount and the sealing effect of the sealing ring 4 is improved by enabling the sealing ring 4 to be more attached to the base 2.

Further, one side of the cover plate 5 departing from the water inlet 23 is provided with a drainage inclined plane 51. Specifically, the drainage inclined plane 51 that sets up on the apron 5 is in the face of the leaking that the sealing washer 4 is ageing, apron 5 leads to with the inseparable variable factor such as base 2 laminating, can have the drainage inclined plane 51 that the oblique angle formed of stretching out on the sealed lid, and the rivers that will spill pass through drainage inclined plane 51 to the shower nozzle outside, prevent that the cooling water from falling into the heating piece, lead to damaging.

Furthermore, the water outlet 24 and the connection between the water outlet 24 and the water passing groove 21 are both provided with a guide inclined plane 25. In this embodiment, the guide slope 25 is provided to reduce the size of the hole at the connection between the water outlet 24 and the water passing groove 21, thereby increasing the pressure during water injection.

Further, the base 2 is fixedly connected with an RGB lamp strip. In this embodiment, the RGB light bars can be used for illumination on the one hand and increase the aesthetic appearance of the device on the other hand. In other embodiments, the RGB light bars can be replaced by light emitting diodes.

Further, the base 2 and the cover plate 5 are detachably connected by screws 7. In this embodiment, the base 2 and the cover 5 are detachably connected by screws 7 so that they can be removed when necessary, for example, to replace the sealing ring 4.

In an embodiment, the discharge end of choke 8 is provided with heating aluminium piece 81 and the discharge gate is provided with nozzle 82, and heating aluminium piece 81 can heat the consumptive material of the ejection of compact in choke 8 and make things convenient for the consumptive material ejection of compact, and pressure when nozzle 82 strengthens the consumptive material ejection of compact for with concentrating when the consumptive material ejection of compact.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
