[0024] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0025] The technical solution of the utility model proposes a cooling water channel passing through a BOSS column and a sleeve structure.

[0026] Reference Figures 1 to 2 , in this embodiment, including:

[0027] Mold 1, provided with an injection cavity;

[0028] A cooling water channel 2 is provided in the mold 1, one end of the cooling water channel 2 is connected to the outside, and the other end passes through the mold 1 and is connected to the injection cavity;

[0029] A BOSS column 31 is provided in the mold 1. The lower end of the BOSS column 31 is connected to the bottom end of the mold 1, and the upper end is connected to the injection cavity. The BOSS column 31 is provided through the cooling water channel 2.

[0030] The sleeve 32 is sleeved on the outside of the BOSS column 31, the sleeve 32 is passed through the cooling water channel 2, and the sleeve 32 is slidably connected to the outside of the BOSS column 31;

[0031] The water-through insert 4 is sleeved at the connection between the sleeve 32 and the cooling water channel 2 . A sliding groove 42 is provided in the water-through insert 4 , and the sleeve 32 is passed through the sliding groove 42 . An annular groove 41 is provided in the water-through insert 4 , and the annular groove 41 is connected to the cooling water channel 2 .

[0032] Optionally, in this embodiment, the cooling water channel 2 passing through the BOSS column 31 and the sleeve 32 structure includes a mold 1, a cooling water channel 2, a BOSS column 31, a sleeve 32 and a water insert 4. The mold 1 is provided with an injection cavity for injection molding of the product. The cooling water channel 2 is provided in the mold 1, and one end of the cooling water channel 2 is connected to the outside world, and the other end is provided in the mold 1 and connected to the injection cavity, that is, one end of the cooling water channel 2 is connected to the external water source, and the external water source enters the mold 1 through the cooling water channel 2 and is connected to the injection cavity through the cooling water channel 2. The plastic cavity connection, that is, through the setting of the cooling water channel 2, the mold 1 and the injection molded product are cooled, the injection molded product and the molding speed are accelerated, and the temperature inside the mold 1 is reduced; the BOSS column 31 is passed through the mold 1, and the lower end of the BOSS column 31 is connected to the bottom end of the mold 1, and the upper end is connected to the injection cavity, and the BOSS column 31 is set through the cooling water channel 2. Due to the structural change of the mold 1, it is necessary to insert the BOSS column 31, and the BOSS column 31 is set through the cooling water channel 2, which usually destroys the water transportation of the cooling water channel 2. The sleeve 32 is sleeved on the outside of the BOSS column 31, and the sleeve 32 is also passed through the cooling water channel 2. The sleeve 32 is slidably connected to the outside of the BOSS column 31, and the up and down sliding of the sleeve 32 can complete the ejection of the product; the water-through insert 4 is sleeved at the connection between the sleeve 32 and the cooling water channel 2, and a sliding groove 42 is provided in the water-through insert 4, and the sleeve 32 is passed through the sliding groove 42; an annular groove 41 is also provided in the water-through insert 4, and the annular groove 41 is connected to the cooling water channel 2, that is, the cooling water in the cooling water channel 2 flows from one end of the cooling water channel 2 through the annular groove 41 and flows out from the other end. Due to defects or poor precision in the early research and development of the mold 1, the structure of the mold 1 needs to be changed, so it is necessary to modify the mold 1 in the mold 1. A BOSS column 31 is inserted in the middle. There is a deviation in the insertion of the BOSS column 31, which causes it to be inserted in the cooling water channel 2, thereby causing the cooling water channel 2 to be scrapped and the mold 1 needs to be replaced. By arranging a water-through insert 4 at the connection between the sleeve 32 and the cooling water channel 2, the sleeve 32 completes the ejection of the product while the setting of the water-through insert 4 can also ensure the continued operation of the cooling water channel 2, thereby remedying the cooling water channel 2. There is no need to replace the mold 1 or redesign the cooling water channel 2. Through the setting of the above-mentioned device, after the structure of the mold 1 is changed, that is, after the cooling water channel 2 is penetrated by the BOSS column 31, the cooling water channel 2 can still be used normally, and there is no need to change the structure of the cooling water channel 2, which saves a lot of time and saves costs.

[0033] Optionally, in this embodiment, a waterproof rubber ring is further provided at the connection between the water-passing insert 4 and the sleeve 32, and the waterproof rubber ring includes a first waterproof rubber ring 51 and a second waterproof rubber ring 52. The first waterproof rubber ring 51 is provided at the connection between the upper end of the water-passing insert 4 and the sleeve 32, and the second waterproof rubber ring 52 is provided at the connection between the lower end of the water-passing insert 4 and the sleeve 32. That is, through the provision of the first waterproof rubber ring 51 and the second waterproof rubber ring 52, the connection between the water-passing insert 4 and the sleeve 32 is sealed, that is, water is prevented from flowing out of the connection when flowing through the annular groove 41, thereby achieving a waterproof effect. Furthermore, the waterproof rubber ring can be made of materials with good waterproof performance such as rubber rings, silicone rings or nylon rubber rings, which are not limited here.

[0034] Optionally, in this embodiment, the cross-sectional area of the annular groove 41 within the water-passing insert 4 is the same as the cross-sectional area of the cooling water channel 2. That is, by ensuring that the cross-sectional area of the annular groove 41 is the same as the cross-sectional area of the cooling water channel 2, the water flow rate flowing through the annular groove 41 is the same as the water flow rate of the cooling water channel 2. As a result, after the cooling water channel 2 is damaged and pierced, it can still operate normally and the water flow rate can remain unchanged. In other embodiments, the cross-sectional area of the annular groove 41 within the water-passing insert 4 can also be slightly different from the cross-sectional area of the cooling water channel 2, so that the operating flow rate of the cooling water channel 2 is not much different from that before the damage. This is not limited here.

[0035] In this embodiment, the mold 1 includes a base plate 11, a fixed mold 12, a front mold 13 and a rear mold 14. The fixed mold 12 is arranged above the base plate 11, the front mold 13 is arranged at the upper end of the fixed mold 12, and the rear mold 14 is connected to the front mold 13, and the front mold 13 and the rear mold 14 jointly surround and form an injection cavity, which is used for injection molding of the product; the lower end of the BOSS column 31 is connected to the base plate 11, and the upper end is connected to the rear mold 14; further, the cooling water channel 2 passing through the BOSS column 31 and the sleeve 32 structure also includes a pressing block 6, which is arranged in the base plate 11, and the lower end of the BOSS column 31 is connected to the pressing block 6, which is used to fix the BOSS column 31 to ensure that the position of the BOSS column 31 in the mold 1 is stable and will not be displaced or loosened due to injection pressure or movement of the mold 1, reducing the shaking and friction of the BOSS column 31 during the movement of the mold 1, thereby extending the service life of the mold 1.

[0036] In this embodiment, the cooling water channel 2 is provided through the fixed mold 12 and the front mold 13, and a waterproof component 53 is provided at the connection between the cooling water channel 2 and the front mold 13. The provision of the waterproof component 53 prevents water from flowing out of the connection between the cooling water channel 2 and the front mold 13, thereby affecting the operation of the mold 1. Furthermore, in this embodiment, the cooling water channel 2 is provided in multiple groups, and the BOSS columns 31 and sleeves 32 are also provided in multiple groups. Each group of BOSS columns 31 is provided in a group of cooling water channels 2, that is, the water inserts 4 are also provided in multiple groups. The provision of multiple groups of cooling water channels 2 can improve the cooling efficiency of the product, accelerate the molding rate of the product, and improve the injection molding efficiency of the product.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
