Abstract
The utility model discloses a casting mould structure, and provides a resin sand standard test bar mould which is good in test bar quality and high in pouring efficiency, and can accurately reflect material performance of casting products. The mould solves the technical problems that a test bar in the prior art is low in pouring efficiency and poor in quality, and defects are prone to being generated so that indexes of the material performance of the casting products can not be reflected accurately. The mould comprises a lower mould and an upper mould matched with the lower mould, wherein a plurality of test bar cavities are distributed in parallel between the lower mould and the upper mould, the same side ends of the test bar cavities are communicated with a direct pouring channel, and the direct pouring channel extends out of the test bar mould and are communicated with a sprue on the outer wall face of the test bar mould.
Description
Technical field
The utility model relates to a kind of casting mould structure, and it is good to relate in particular to a kind of coupon quality, can accurately reflect the resin sand standard coupon mould of cast product material capability.
Background technology
In order to detect the material capability index of cast product, usually when pouring cast part, water with same iron clad water and outpour some coupons, again coupon being carried out testing performance index gets final product, and existing coupon casting mold is normally used green sand molding, not only efficient is low, and coupon is easy to produce defective, directly affect the accuracy of castings material performance indications detection when serious calmly.
Chinese patent discloses the mould (CN202343865U) of a kind of aluminium alloy antigravity sand casting coupon moulding, it comprises box-frame, stalk interface apperance, coupon pattern sample, lower box-frame, wherein coupon pattern sample is the unitary mould structure, is provided with sprue, cross gate, 1/2 coupon apperance, alignment pin and positioning sleeve at coupon pattern sample.Although this mould structure adopts the resin sand moulding, molten iron enters the coupon die cavity during cast after cast gate place elder generation is by cross gate and sprue, and efficient is low, and coupon is of poor quality, and the same defective that easily produces of coupon, causes accurately reflecting the material capability index of foundry goods.
Summary of the invention
It is good that the utility model has mainly provided a kind of coupon quality, cast efficient is high, the resin sand standard coupon mould that can accurately reflect the cast product material capability, it is low to have solved the coupon cast efficient that exists in the prior art, of poor quality, coupon easily produces defective, thereby can't accurately reflect the technical problem of the material capability index etc. of foundry goods.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of resin sand standard coupon mould; comprise that counterdie reaches and the patrix of counterdie interworking; parallel is shown several coupon die cavities between described counterdie and patrix; the same side of coupon die cavity is communicated with and is provided with sprue, and it is outer and be connected with cast gate on the coupon mould outside wall surface that sprue extends to the coupon mould.Molten iron carries over simultaneously sprue from cast gate and enters the coupon die cavity during cast, because the coupon die cavity is arranged in parallel between the mating surface of upper and lower mould, therefore molten iron enters each coupon die cavity simultaneously, each moulding coupon uniform quality, simultaneously because molten iron directly enters the coupon die cavity through sprue, therefore coupon cast efficient is high, has improved production efficiency; To half-open resin sand mould, good permeability, product surface is bright and clean, and the degree of packing is good, and the coupon Forming Quality is good, thereby guarantees that any coupon all can accurately reflect the material capability index of foundry goods.
As preferably, horizontal opening groove before on described counterdie, being provided with corresponding to an end of the mating surface of patrix, be provided with front horizontal ledge with front horizontal opening groove interworking at patrix, horizontal ledge after being provided with corresponding to the other end of the mating surface of patrix on the counterdie is provided with rear horizontal opening groove with rear horizontal ledge interworking at patrix.By the mating surface at upper and lower mould horizontal ledge and the horizontal opening groove of interworking are set, avoid upper and lower mould the front-back staggered phenomenon to occur, thereby guaranteed the Forming Quality of coupon.
As preferably, described coupon die cavity is equidistant to be arranged and be symmetrical up and down between counterdie and patrix.In the situation of each coupon mold cavity forming term harmonization, guarantee the quality of coupon.
As preferably, described cast gate is the long arc shape groove, and the mating surface of the relative counterdie of cast gate and patrix is symmetric, and the length direction of cast gate is consistent with the orientation of coupon die cavity.When the length direction of cast gate is consistent with the orientation of coupon die cavity, can guarantee that molten iron enters the coupon die cavity simultaneously from cast gate, thereby guarantee each coupon mold cavity forming coupon uniform quality.
As preferably, described sprue is coaxial to be arranged on corresponding coupon die cavity one end, and the relative sprue of cast gate is symmetrical.Sprue is coaxial with the coupon die cavity, and when namely sprue and cast gate were in vertical distribution, molten iron entered each coupon die cavity simultaneously, and the coupon casting quality is good.
Therefore, resin sand standard coupon mould of the present utility model has following advantage: to half-open resin sand mould, good permeability, product surface is bright and clean, the degree of packing is good, and the coupon Forming Quality is good, thereby guarantees that any coupon all can accurately reflect the material capability index of foundry goods; Upper and lower mould avoids upper and lower mould inconsistent phenomenon to occur by horizontal ledge and the horizontal opening groove location of interworking, further guarantees the Forming Quality of coupon.
