Abstract

The utility model discloses a kind of spring block sand core structure, be applied on the casting sand type of spring block, core is approximate rectangular structure, the cast die cavity of spring block is arranged with at the corner location of core, the cast die cavity of described spring block is symmetrical arranged between two, the structural design thus formation one core more than one piece symmetry is carried a load.Core boxlike of the present utility model designs and produces, and adopt entirety to carry a load core, a core more than one piece, enhances productivity.By load carrying type symmetric design, determine that center, sand box four limit is Hoisting Position, middle part is in core counterdie center stationary positioned, therefore, the mutual counteract of buoyancy of core four lateral suspension end, makes core core box held stationary, thus ensures that casting dimension is accurate, uniform wall thickness.

Description

Spring block sand core structure

Technical field

The utility model relates to technical field of automobile parts, and more particularly, it relates to a kind of spring block sand core structure scheme.

Background technology

Spring block is a kind of important parts on automobile, it is an approximate rectangular structure with two adjacent surfaces opening, therefore, its structure limits the fixed form of casting sand core, the suspension end of core easily upwards departs from by the pressure of molten iron floating, make the became uneven of spring block even, thus affect the accuracy to size of foundry goods.Therefore, designer takes into full account dimension precision requirement, the mode of production of rough casting, adopts the core design of symmetrical structure of carrying a load in the casting die of spring block.

Utility model content

It is scientific and reasonable for structure that the purpose of this utility model is to provide a kind of casting process, the spring block sand core structure of the overall stationarity of core can be ensured according to design of part feature, effectively can overcome the impact of core buoyancy on core suspension end, ensure that the dimensional accuracy of foundry goods, and a core more than one piece, improve spring block production efficiency, to overcome deficiency existing in prior art.

The technical scheme in the invention for solving the technical problem is: spring block sand core structure, be applied on the casting sand type of spring block, core is approximate rectangular structure, the cast die cavity of spring block is arranged with at the corner location of core, the cast die cavity of described spring block is symmetrical arranged between two, the structure thus formation one core more than one piece symmetry is carried a load.

In the level of core, separated time arranges running gate system.

In the bottom of core, core footing is set.

Described core footing is criss-cross, comprises horizontal fulcrum and perpendicular fulcrum, and described horizontal fulcrum is longer than perpendicular fulcrum.

The beneficial effects of the utility model are:

Core boxlike of the present utility model designs and produces, and adopt entirety to carry a load core, a core more than one piece, enhances productivity.By load carrying type symmetric design, determine that center, sand box four limit is Hoisting Position, middle part is in core counterdie center stationary positioned, therefore, the mutual counteract of buoyancy of core four lateral suspension end, makes core core box held stationary, thus ensures that casting dimension is accurate, uniform wall thickness.

Detailed description of the invention

Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.

In description of the present utility model, it will be appreciated that, term " " center ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristic.Thus, be limited with " first ", the feature of " second " can express or impliedly comprise one or more these features.In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more.

In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should make broad understanding, such as, can be fixedly connected with.Also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition above-mentioned term can be understood at concrete meaning of the present utility model.

As Figure 1-4, spring block sand core structure, be applied on the casting sand type of spring block, core 1 is approximate rectangular structure, the cast die cavity 2 of spring block is arranged with at the corner location of core, the cast die cavity 2 of described spring block is symmetrical arranged between two, the structural design thus formation one core more than one piece symmetry is carried a load.Spring block casting structure is comparatively simple, but casting design core print positioning accuracy request is high, and the utility model is according to spring block design feature, adopt core that is symmetrical, structure of carrying a load, ensure that the steady of core, ensure that the dimensional accuracy of foundry goods, and four, a core, improve production efficiency.Spring block integral sand core adopts resin sand to make, and determine that position location is core centre position, Hoisting Position is four centers, limit.

Further, can by part Design of Runner System on core.In the level of core, separated time arranges running gate system, in core, establish heavy chamber 3 to form the ingate of running gate system.Arrange core footing 4 in the bottom of core, core footing 4 is criss-cross, comprises horizontal fulcrum 5 and perpendicular fulcrum 6, and wherein, horizontal fulcrum is longer than perpendicular fulcrum.

The design that spring block core is concrete and production procedure as follows:

1): demonstration;

2): core box layout design:

3): core mould is processed;

4): core makes, assembling loam core, brushing paint;

5): moulding is poured into a mould;

6): casting cleaning, polishing;

7): product size is checked.；

All the other structures are all known according to other formations of spring block sand core structure of the present utility model and operation to those skilled in the art, are not described in detail here.

Although illustrate and described embodiment of the present utility model; those of ordinary skill in the art is to be understood that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and aim; scope of the present utility model limited by claim and equivalent replacement thereof; in the improvement etc. done without creative work, all should be included within protection domain of the present utility model.
