The utility model relates to a low pressure casting mold for an amplifier case, which is used for the low pressure casting of the aluminium alloy casing of an amplifier arranged in diffusing silicon differential pressure and pressure transmitters in an electronic type. The structural characteristics are that the parting surfaces of a moving and stationary molds are arranged on the upper plane surface of the casing of an amplifier, the side opening parting surface of a fixed die insert is composed of three vertical plane which pass through the axis of the cylinder of a step and a pouring head, and an anomalous sand core forming the cross bore of the U-shaped hole of a work piece is hung and arranged between two vertical mold cores arranged on the moving mold. The utility model has the advantages of simple structure, exhaust fluency, low cost, uniform solidify, good quality, etc. The utility model can be used in technological equipment which are provided with the analogous parts of amplifier casings.
Description
The utility model relates to a kind of amplifier aluminum alloy casing die casting that is used for diffuse silicon electronics differential pressure, pressure transmitter.
Present domestic introduced Japanese diffuse silicon electronic type differential pressure, pressure transmitter product technology.Because amplifier housing cavity structure more complicated, the castability of this product are had relatively high expectations, therefore adopt the foundry engieering of domestic widespread usage to be difficult to guarantee the casting and the crudy of this shell.
The purpose of this utility model is to provide a kind of casting mould that is used for above-mentioned amplifier housing of rational in infrastructure, easy to operate and handling ease.
The purpose of this utility model can realize by following structure or measure:
The basic configuration structure of the amplifier aluminum alloy casing in diffuse silicon electronic type differential pressure, the pressure transmitter is the parallel step cylinder that connects together of big or small axis in the approximate cucurbit shape cross section of its profile.On the same plane of small stair cylinder upper right and front side, vertically pass through the little round platform of 90 ° of angles between two respectively mutually.The axis of two little round platforms and big step cylinder axis linear distance are all less than two step cylinder axis linear distances.Side's body is passed through on the right side mutually after big step cylinder top is near the cucurbit waist, and these side's body top and bottom are parallel with the axis of little round platform, two sides respectively with the axis normal of two little round platforms.The last planar open of cucurbit cross section stepped cylinder, the lower plane sealing.The big cylindrical lower plane of step passes through a tubing string that is communicated with inner chamber that axis is overlapping mutually.The inner chamber basic configuration of amplifier housing is made of the special-shaped through hole of offering at cucurbit shape waist between the big hole that is provided with certain parallel navel platform in the big step cylinder and the step circular hole in the small stair cylinder and big hole and the step circular hole.There is the connect hole vertical with the step circular hole at two roundlet platforms middle part.The utility model determines that according to the design feature of above-mentioned amplifier housing the primary structure of compression mod comprises the dynamic model that connects the supporting core, cover half and other annex that the connection supporting is inserted.Dynamic model mainly comprises Bottom clamp plate 1, push pedal 2, ejector pin retaining plate 3, push rod, core support plate 4, push pedal guiding release link 5, core 6,7,8 and location securing member.Cover half mainly comprises top clamping plate 9, fixed die insert 10,11,12, core 13, guide pillar 14, the side of inserting are convinced post 15, cast gate 16 and location securing member and cooling structure such as loose core by patient analysis down.Special feature of the present utility model is parting Surface Design plane on amplifier housing of dynamic model and cover half.Fixed die insert 10 and 11 thickness respectively with the step of amplifier housing cylindrical top bar and get out of a predicament or an embarrassing situation highly identical.Cast gate 16 be arranged on relative amplifier housing approximate cucurbit waist lower plane insert 12 and top clamping plate 9 on.Fixed die insert 10,11,12 sides that are fixed as one are opened die joint and are made of three continuous vertical planes.One from the left side edge of inserting by big step cylinder axis and divide tubing string side boss that its lower plane passes through mutually equally to cucurbit waist near amplifier housing.Its two near the cucurbit waist of amplifier housing by cast gate 16 to the cylindrical axis of small stair.Its three roundlet platform axis that passes through mutually by small stair cylinder right flank from the cylindrical axis of small stair is to the right side edge of inserting.Clamping has the core 8 of the special-shaped through hole that formation amplifier housing cucurbit shape waist offers between the core 6 that special feature of the present utility model also is big hole in forming big step cylinder and the core 7 that forms step circular hole in the small stair cylinder.Core 8 can be designed to coat the core that the coating oven dry be made up of lead powder, waterglass, water forms by sand, mud, water, the matrix formed.Offer two special-shaped levels in core 6 relative cucurbit shape waist sides, and constitute an inclined-plane and core 8 front and back of lifting can not be moved.Form a platform in core 6 sides upper end, core 8 upper ends platform thus limit the upright position, when the aluminium alloy fluid injection has the pressure stamp, impact motionless core 8 and the position stability of assurance core 8 like this.The right side of core 8 is leaned on to the end side surface of core 7 and is limited position, the left and right sides.Reliable for core 8 is installed, can core 6 with core 8 contact-making surfaces on bore an aperture, insert core 8 by aluminium wire and be connected with aperture.But special feature of the present utility model also is to insert that little round platform that 10 front side, the relative amplifier housing small stair of first half cylinder top passes through mutually and small stair cylinder upper right pass through mutually at the square build chamber arranged outside pull Wedge-type red copper heat absorption chill 17 that 10 the latter half of relative amplifier housing rear side inserted passes through mutually is but that the roundlet platform axis hole position that the fixed die insert side is opened on the die joint is provided with pull shaft type red copper heat absorption technology core 18,19 respectively.Special feature of the present utility model also is the setting of exhaust structure.Between moving, the cover half die joint, exhaust trench distributes on cover half.The fixed die insert side is opened die joint by the nature exhaust of matched moulds gap.Convince by patient analysis to cooperating on the facade exhaust slot is set in top clamping plate 9 10,11,12 sides of inserting relatively.Insert 12 with top clamping plate 9 horizontal mating surfaces by the exhaust of fit clearance nature.11,12 the horizontal fixed of inserting is offered exhaust trench respectively above cooperating.By piece 20 sealings, be provided with exhaust apertures between the leading flank of piece 20 and the square build chamber lateral surface that the 10 latter half of relative amplifier housing rear sides of inserting pass through mutually above the chill 17.Each core is corresponding between the mating surface with it to be provided with certain exhaust apertures.
