Definitions
- the present invention relates to a ventilation valve, in particular for ventilating a casting mold for production of shield insulators according to the preamble of Claim 1.
- the object of the present invention is to be achieved the harmful deformation of castings of any kind when Demoulding from the mold by using a new kind Avoid ventilation valve.
- the ventilation valve according to the invention is quick and simple to clean because the valve body from the valve body easily disassemble and so outside a mold or the like. can be cleaned.
- the ventilation valve according to the invention can also be used for other ventilation measures, especially in other demolding processes, in which a vacuum forms or can form.
- a part of a shield insulator is designated, the one Core 2 or a core wall formed as a hollow body and a screen 3 formed thereon with a molded cuff 4 has.
- the core 2 consists of a with reinforcing means, especially glass fibers, reinforced Insulating material, preferably made of silicone.
- About core 2 is a one-part or multi-part form 5 pushed to one shaping screen 3 with cuff 4 shaped accordingly has funnel-shaped cavity 5.1.
- the cuff 4 forming part 5.2 of the mold space 5.1 has at the cuff end 4.1 an annular gap 6, which for the casting process by a elastic seal 7, for example a ring or O-seal is complete.
- the shape 5 is on the side a rod or pin-shaped ventilation valve 8, for example in the form of a plate or cone valve.
- the Ventilation valve 8 can be screwed into the mold 5 or, for example tightly inserted and by means of a grub screw or the like.
- the outer surface 8.1 advantageously projects of the ventilation valve 8 to the surface of the screen 3 or up to the surface 4.2 of the sleeve 4 of the screen 3. In particular, it is flush with the surface of the mold 5.
- a screen 3 with a cuff 4 first form 5 to the assigned place on core 2 or brought to the core wall and with the elastic seal 7th sealed. Then the mold space 5.1 from above filled with a casting material, which then becomes insulating body solidifies. Serves as a suitable material a non-reinforced or reinforced, initially pourable and then polymer which solidifies by crosslinking Material, especially silicone. This material combines when networking with the material of the core 2 or the core wall. After the poured material has hardened or solidified the form 5 together with the seal 7 in the drawing moved down. In the resulting cavity This creates a vacuum which, if valve 8 is not present, pulls the screen 3 down particularly at the outer edge, whereby tensions or even cracks can develop on its top.
- the ventilation valve 8 as in the Rest position valve in the closed position educated. It consists of a rod or pencil-shaped Valve housing 8.2 and one in an axial extension this valve housing 8.2 screwable or in this screw-in valve body 8.3. In a preferred central to the valve compartment 8.2.1 of the valve housing 8.1 coaxial bore 8.3.1, a pull rod 8.4 is displaceable guided.
- the pull rod 8.4 projects through the valve space 8.2.1.
- a valve piston 9 with a Seal 10 provided at the end 8.4.1 of the pull rod 8.4 is a valve piston 9 with a Seal 10 provided.
- the latter is in the resting position of the Ventilation valve 8 at a valve opening 8.5 of the outer surface 8.1 of the valve housing 8.2 by sealing over a Compression spring 11 is held in the closed position.
- the Compression spring 11 between a pressure surface 8.3.2 of the valve body 8.3 and one in the area of the valve space 8.2.1 on the Drawbar 8.4 provided stop flange 8.4.2 or on the Back 9.1 of the valve piston 9 clamped.
- the valve housing 8.2 has an air inlet opening 8.2.2, via the 8 air or another with the ventilation valve open Gaseous medium flow into the valve compartment 8.2.1 and over the valve opening 8.5 can flow out.
- the valve piston 9 is preferably with lateral overflow channels 9.2 and possibly also the seal 10 with correspondingly arranged lateral overflow channels 10.1 provided.
- the mode of operation of the ventilation valve 8 according to the invention is as follows:
- mold 5 is the casting material described above cast. After it solidifies, the shape becomes 5 together with the elastic seal 7 in the drawing pushed down. At the same time - or preferably a little earlier - the ventilation valve 8 is opened and thus the mold 5 ventilated so that the cast screen 3 easily and without Damage can be removed from the mold 5.
- a major advantage of the new ventilation valve 8 is in that the valve housing 8.2 used in the form 5 and for example fastened with a grub screw in the form 5 can be, while on the other hand the valve body 8.3 with Drawbar 8.4, compression spring 11, valve piston 9 and seal 10 easily released and removed from the valve housing 8.2 can be. These removed parts can then be outside the Form 5 can be cleaned if, for example Overflow channels 9.2 and / or 10.1 with the casting resin, in particular Silicone, should have added. Can too individual parts can be easily replaced. The valve housing 8.2 therefore remains firmly connected to Form 5. The cleaning and a possibly necessary replacement of parts can therefore faster and more convenient than an inseparable one Ventilation valve forming unit.
