Abstract
The present invention relates to a core casting and manufacturing mould which is mainly used for the manufacture of a mud core of an inner mould of an automobile brake drum and belongs to the field of a casting mould. A core box bottom and a clamping spoke form an outer mould. The lower end of the clamping spoke is connected with the upper end of the core box bottom. The bottom of an inner cavity of the core box bottom is provided with a groove, and the center of the inner cavity of the core box bottom is provided with a through hole. The lower end of a core rib is provided with a core rib head, and the upper end of the core rib is provided with a flange handle structure. The clamping spoke can be longitudinally and symmetrically divided into two half fission structures, and can also form an integral structure with the core box bottom. The present invention has the advantages of easy control of core manufacturing quality, convenient core taking, high manufacturing efficiency, good exhaust performance, high casting quality, high efficiency, environmental protection, energy saving, etc.; core arrangement can not shift; a requirement for the technical level of a worker is low.
Description
Technical field: the present invention relates to a kind of casting core mould, be mainly used in the making in automobile brake drum internal mold loam core, belong to the casting mould field.
Background technology: at first need in the foundry technology process to make husky mould according to part shape, make the die cavity consistent with the part blank at Sha Mozhong, pouring molten iron obtains the part blank then.Some part inside is hollow mechanism, therefore need be in husky model cavity certain position join and put the loam core, inaccurate if put the position, loam core, then can cause foundry goods defective.The manufacture craft of the husky mould of traditional handicraft, particularly automobile brake drum adopts to be made by hand, and control position, loam core difficulty, casting yield is low, foundry goods allowance is big, and labour intensity is big, work efficiency is low.Chinese patent ZL01214020.1 patent " efficiently, environmental protection, energy-saving mold and pattern for casting tool " has proposed a kind of this type of and has cast the making mould of husky mould, be specially adapted to make automobile brake drum and cast husky mould, but this type of loam core that casts husky mould still mainly makes of conventional method, to workman's technical merit require high, fill out that husky pickup inconvenience, efficient are low, the loam core quality is difficult for ensureing, and the venting quality difference in loam core and easily cause bleb and folder is husky, also cause core shift down during core easily.
Summary of the invention: be to solve the problems referred to above that mo(u)ld core, particularly automobile brake drum mo(u)ld core exist in making, the invention provides a kind of quality be easy to control, get that core is convenient, make efficiency is high, venting quality good, down can core shift during core, workman's technical merit is required low efficient, environmental protection, energy-saving casting core mould.
To achieve these goals, the invention provides following technical scheme: produce automobile brake drum casting sand mo(u)ld mould, it is characterized in that mould is made up of core box mould, arbor, the combination of lumens constituent part blank loam core shape of core box mould, there is the positioning through hole that inserts the location for arbor at core box mold bottom center, and the arbor lower end can be useful on the arbor head of location; The core box mould constitutes at vertical symmetrical dimidiation, and core box mould appearance is useful on the card spoke that fixedly ear that they are connected or core box mould be symmetrically distributed with two halves at the bottom of by core box and constitutes jointly, and appearance is useful on the fixedly ear that they are connected; Perhaps be integral structure at the bottom of card spoke and the core box in the core box mould, its card spoke inwall has pattern draft; Perhaps the core box mould constitutes with the entire card spoke on top at the bottom of by the core box of bottom, and its card spoke inwall has pattern draft; Locate by concavo-convex fit structure or alignment pin, locating hole, locating slot socket the upper end at the bottom of card spoke lower end and the core box, and intracavity bottom has corresponding groove at the bottom of the core box, but groove draw-in groove or cotter way; Arbor can be hollow netted, vertical bar shape, irregular cross-like, perhaps tubulose, and its outer tubular wall is held sand with lattice framing or projection, and there are inner flange or outward flange handgrips in the arbor upper end.
Card spoke 2 also can divide body structure by vertical symmetrical dimidiation, and its binding site is that location structure, the appearance of concavo-convex cooperation is useful on their fixing fixedly ears 4.
1 also can be integral structure at the bottom of card spoke 2 and the core box, and arbor 3 can be hollow or solid construction.Making such as entire die and arbor available metal material, fiberglass, organic synthesis material.
The present invention is owing to adopt the card spoke and the core box bottom die structure of arbor and the easy accessibility have location structure and pickup handle, thus have that the coremaking precision is easy to guarantee, produce core processing ease, the technical merit that does not need to ask the workman, make efficiency height, advantage that can core shift when core is played because of positioning head is arranged in the loam core that obtains; Simultaneously, the loam core degree of packing that obtains is even, steam discharge is even, outward appearance is clean and tidy, makes defectives such as bright and clean, the no burning into sand of cast(ing) surface after the moulding, pore, has significantly reduced allowance, has saved molten iron.
Description of drawings: further specify essence of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the cross-sectional schematic of invention mould, and wherein arbor head (5) is the convex-concave fit structure.
Fig. 2 schematic top plan view of the present invention, wherein the core box mould is the symmetrical two halves of dividing equally.
