Description of the invention: [Technical field to which the invention pertains] The present invention relates to a gas permeable assembly. [Prior Art] " During the in-mold molding process, the mold gas generated during injection molding may cause the plastic parts to burn or not completely fill, and the product may wrinkle or corrugate, and the back pressure in the mold may be delayed. The flow of the injected material, so the mold design must fully consider the exhaust problem, which has been a difficult problem in the industry, and as the mold structure becomes more complex, the exhaust difficulty increases. The conventional solution is _ using a parting surface plus a venting groove, a mold plus a vent or other additional means to vent. However, when a mold is used to generate a large amount of gas, the conventional method does not have an exhaust effect. In order to solve this problem, a porous member made of a porous mold steel is inserted into the mold core. The partial volume of the porous mold steel is distributed with loose pores, and the loose pores are connected to each other for gas to permeate, and the gas permeable component can be used. Achieve rapid exhaust. However, the porous mold steel has poor toughness and hardness, is prone to cracking, and cannot be welded after rupture, so that the ventilated component made of the steel has a high cost, and is easily clogged due to loose pores, and the maintenance process is complicated. [Description of the Invention] In view of the above, it is necessary to provide a permeable member that is weldable and easy to maintain. a venting component, comprising a plurality of gas permeable sheets, a first fixing member and a second fixing member, wherein the gas permeable sheets are fixed between the first fixing member and the first fixing member, and each of the gas permeable sheets is provided Multiple breathable slots. Compared with the prior art, the gas permeable portion of the gas permeable component is formed by combining a plurality of gas permeable sheets. When some of the gas enthalpy sheets are damaged, the gas permeable sheets or welding can be individually replaced, thereby reducing manufacturing and maintenance costs. [Embodiment] Please refer to Fig. 1 and Fig. 1 is a first 61303601 first fixing member 30 and an embodiment of the venting assembly of the present invention, which includes a plurality of gas permeable sheets and a second fixing member 40. Each of the gas permeable sheets 10 includes two side surfaces u parallel to each other, and each of the side surfaces π is provided with a plurality of gas permeable grooves 13 which are parallel to each other, and the gas permeable grooves 13 have a V-shaped cross section. The first locking hole 15 and the plurality of positioning holes 17. The first fixing member 30 has the same shape as the one of the gas permeable sheets 1 but has a thickness corresponding to the first locking hole 15 of the gas permeable sheet 10; a locking hole 31, a positioning hole 17 corresponding to the gas permeable sheet 1 is provided with a plurality of positioning holes 33. The shape and thickness of the second fixing member 4 are similar to the first fixing member. The first locking hole 15 corresponding to the gas permeable sheet 10 is provided with a screw hole 41, and the positioning hole 17 corresponding to the gas permeable sheet 10 is provided with a plurality of clamping holes 43. When loading, the plurality of fixing pins 70 are sequentially inserted. The positioning holes 3 and Ϊ, the plurality of bolts 50 are sequentially passed through the second locking holes, and the locking holes 15' are locked to the corresponding screw holes 4, so that the first bolts and the zeros are installed. The fixing member 30 and the second fixing member are made into a gas permeable component, and the assembly of the gas permeable component is completed as shown in Fig. 2 'in the outside or the gas itself is pressed Under the force, the gas J ehai 4 is discharged through the trough 。3. - Continue to refer to the fourth and fifth figures, which are the gas generating components, each of the gas permeable sheets has a 疋3 complex 孔 hole 17, and a plurality of vacancies 19, the fourth 40th, the handicap Η' is provided with a plurality of notches 35, the second fixing member 43, and the plurality of notches 45, . , , and the sighs of the plurality of holes, the plurality of fixed pins 70, which are sequentially inserted into the Positioning holes 33, 17, 17, 43, 71303601 and mounting the gas permeable sheets 10' between the first fixing member 30' and the second fixing member 40', and welding the notches 35', 19 ', 45', the formed plurality of welding wires 80' can connect the first fixing member 30', the gas permeable sheets 10' and the second fixing member 40' into one body, thereby forming a gas permeable component. The gas permeable sheet 1〇, 1〇', the first fixing member 30, 30' and the second fixing member 40, 40' can be made of ordinary steel materials, so the toughness and hardness of the gas permeable component are not limited, and can be welded The venting component of the invention can be used not only for the exhaust of the mold, but also for other mechanical devices requiring exhaust, and the venting group It can be made according to actual needs, different shapes, and is not limited to the rectangular parallelepiped shown in the above embodiments. The cross-sectional shape, size and density of the gas permeable grooves 13, 13' can also be adjusted according to the actual ventilation requirements.
