Description
Technical field
The utility model relates to casting technology field, a kind of especially low pressure casting formation die core for base product.
Background technique
Base is the important component of auto parts, is currently used for the base product of new-energy automobile, primary structure
For cylindrical body, inner wall is shiny surface, and when production needs to form by low pressure casting, but due in casting process molten metal inject mould
Volume gas is easy to happen when tool type chamber under pressure, position aggregation of the gas on product inner wall can not be successfully, timely arrange
Out, it is easy to cause adverse effect to product, so that the inner wall processed is easy to appear stomata, causes molding effect undesirable.
Utility model content
Problem to be solved in the utility model is to provide a kind of low pressure casting formation die core for base product,
It can play the role of smooth in exhaust in casting process, so that base product quality after molding is relatively preferable.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution: a kind of for the low of base product
Casting forming die core, including columned mold core ontology are pressed, is provided in the axial direction with a plurality of row on the lateral circle surface of the mold core ontology
Gas wire casing, the exhaust wire casing are extended upwardly to the top of mold core ontology, the top of the mold core ontology by the bottom end of mold core ontology
Annular is provided with multiple convex blocks on end face, and the end face outside of the convex block is aligned with the side of mold core ontology, two neighboring convex block
Between form exhaust passage, each exhaust passage is connected to an exhaust wire casing.
Preferably, respectively exhaust wire casing is disposed in an evenly spaced relation on the lateral circle surface of mold core ontology.
It is highly preferred that the quantity of the exhaust wire casing is 40-50.
It is highly preferred that the cross section of the exhaust wire casing is triangular in shape.
It is highly preferred that the width of rebate of the exhaust wire casing is 1-2mm.
It is highly preferred that the convex block with a thickness of 1-2mm.
The utility model has the beneficial effects that: low pressure casting molding is carried out using the mold core, when high-temperature liquid metal is formed
Stream from injection mold cavity after, the lateral surface close to mold core ontology is gradually filled with from lower to upper, in the process, in type chamber
Gas by the exhaust wire casing on mold core ontology lateral circle surface guiding role and smoothly flow up, then into each
It is discharged outward again in exhaust passage, and molten metal stream can also be by the guiding function of the exhaust wire casing on mold core ontology lateral circle surface
And flow, so that base product quality after molding is relatively preferable.Due to being vented the presence of wire casing, base product after molding
The protrusion that multiple vertical stripes are formed on inner wall obtains a kind of new product structure, and raised size can be according to exhaust line
Depending on the setting of slot size, which can meet matching requirements, on using no influence.
Detailed description of the invention
Fig. 1 is the overall structure diagram in the utility model embodiment；
Fig. 2 is the enlarged diagram of structure at A in Fig. 1.
Appended drawing reference are as follows:
1 --- mold core ontology 2 --- exhaust wire casing 3 --- convex block
4 --- exhaust passage.
Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.
It needs to illustrate in advance, in the present invention unless specifically defined or limited otherwise, term " installation ",
The terms such as " connected ", " connection ", " fixation " shall be understood in a broad sense, for example, it may be being fixedly connected, be also possible to detachably connect
It connects, or is integrally connected；It can be directly connected, can also can be inside two elements indirectly connected through an intermediary
Connection.For the ordinary skill in the art, above-mentioned term can be understood in the utility model as the case may be
In concrete meaning.
In addition, in the present invention unless specifically defined or limited otherwise, fisrt feature in second feature "upper" or
"lower" may include that the first and second features directly contact, and also may include that the first and second features are not direct contacts but lead to
Cross the other characterisation contact between them.Moreover, fisrt feature includes above the second feature " above ", " above " and " above "
One feature is right above second feature and oblique upper, or is merely representative of first feature horizontal height higher than second feature.First is special
Sign is directly below and diagonally below the second feature including fisrt feature under the second feature " below ", " below " and " below ", or only
Indicate that first feature horizontal height is less than second feature.Term " on ", "lower", "front", "rear", "left", "right", "vertical", " water
It is flat ", "top", "bottom" "inner", the instructions such as "outside" orientation or positional relationship be to be based on the orientation or positional relationship shown in the drawings,
It is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning must have
Specific orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
As shown in Figs. 1-2, for the low pressure casting formation die core of base product, including columned mold core ontology 1, mold core
A plurality of exhaust wire casing 2 is provided in the axial direction on the lateral circle surface of ontology 1, exhaust wire casing 2 is extended upwardly to by the bottom end of mold core ontology 1
The top of mold core ontology 1, annular is provided with multiple convex blocks 3, the end face outside and mold core of convex block 3 on the top end face of mold core ontology 1
The side of ontology 1 is aligned, and exhaust passage 4 is formed between two neighboring convex block 3, and each exhaust passage 4 and an exhaust wire casing 2 connect
