Description

A kind of sand mould casting mould

Technical field

The production casting field of aluminium alloy car knuckle is the utility model is related to, particularly relates to a kind of sand mould casting Mould.

Background technology

Traditional aluminium alloy knuckle is mainly produced using low pressure casting or the production technology of counter-pressure casting, and is used Low pressure casting or the mould of counter-pressure casting are generally cast using metal die, and not only production cost is high for these production technologies, Efficiency is low, and the requirement to metal die is also very high so that and the exploitation of metal die and maintenance cost are high, construction cycle length, It must also be equipped with when cannot be above all modified well according to the requirement of customer to mould, while manufacture metal die The forcing press auxiliary production of large-tonnage.Using metal die cast out come product be also easy to produce cold shut and shrinkage porosite etc. inside lack Fall into, the serious mechanical performance that have impact on product.Certainly also have and produced by the way of forging, but this mode is not only imitated Rate is low, and the part residual stress forged is big, easily causes the deformation of part and shortens its service life.So In order to pursue light-weight design and overcome metal die produce a series of problems I take charge of R ＆ D design one kind by sand core mould The sand mo(u)ld mould of manufacture is used for pouring into a mould the parts such as stub axle.

Utility model content

In view of the foregoing, the utility model provides a kind of sand mould casting mould, this mould be using resin die come The sand core mould of production, it is developed and maintenance cost is all than relatively low, and the cycle is fast, it is often more important that this mould can be very good according to Gu The requirement of visitor is rapidly performed by mould modification, greatly reduces production cost, also improves production efficiency.

To reach above-mentioned purpose, technical solution is used by the utility model solves its technical problem：

A kind of sand mould casting mould, including upper die structure and lower die structure, the upper die structure are buckled in lower die structure On；The upper die structure is equipped with running gate system；The running gate system includes pouring basin and running channel；The pouring basin position In one jiao on the surface of upper die structure；The running channel includes sprue and cross gate, and sprue is located at the bottom of upper die structure Edge side, cross gate are located at the inside of upper die structure；The upper die structure upper surface side is additionally provided with a riser, riser with Cast top connects；The riser is equipped with the chamfering at certain angle of inclination with cast top junction.

Further, sand mould casting mould is made of sand core sand.

Further, the sand mould casting mould can be also made of tide mould sand.

Further, the running gate system is open system.

Further, it is additionally provided with filter on the cross gate.

Due to the utilization of above-mentioned technical proposal, the utility model can be taken in bench test rack early period compared with prior art Various heavier frock clamps are positioned when building, and this clamp structure is simple, it is cheap, manpower can be saved with batch machining, Efficiency is improved, can be used as fexible unit.

Embodiment

It is in order to make those skilled in the art better understand the technical solutions in the application, real below in conjunction with the application The attached drawing in example is applied, the technical solution in the embodiment of the present application is clearly and completely described, it is clear that described implementation Example is merely a part but not all of the embodiments of the present application.It is common based on the embodiment in the application, this area Technical staff's all other embodiments obtained without making creative work, should all belong to the application protection Scope：

A kind of sand mould casting mould as shown in Figure 1 to Figure 2, including upper die structure 1 and lower die structure 2, the upper mold Structure 1 is buckled on lower die structure 2；The upper die structure 1 is equipped with running gate system；The running gate system includes pouring basin 3 and running channel；The pouring basin 3 is located on the surface of upper die structure 1 one jiao；The running channel includes sprue 41 and cross gate 42, sprue 41 is located at the bottom edge side of upper die structure 1, and cross gate 42 is located at the inside of upper die structure 1；The upper mold 1 upper surface side of structure is additionally provided with a riser 5, and riser 5 is connected with cast top；The riser 5 and cast top junction Chamfering equipped with certain angle of inclination.

Further, sand mould casting mould is made of sand core sand.

Further, the sand mould casting mould can be also made of tide mould sand.

Further, the running gate system is open system.

Further, 42 it is additionally provided with filter on the cross gate.

This casting mold is by sand core sand or tide mould sand system, and sand core sand and resin and curing agent are fully mixed by sand mixer Closing, resin is crosslinked under the action of curing agent, and molecule becomes larger, and has certain space structure and mechanical performance, then by DMPA (ammonia) is catalyzed, and is molded sand core mould moment.Upper die structure and lower die structure are produced using this method, then again by upper Lower die is molded into complete casting mold.Whole running gate system uses open by design, and from casting bottom into pouring, so design can To be molten aluminum is more gently filled cavity, prevent turbulent flow and reduce the generation of volume gas.Set at the same time using roomy riser Meter, cast top design the chamfering of certain gradient with riser junction, gas discharge when being conducive to fill type in cavity.

This mould is the sand core mould to produce using resin die, it is developed and maintenance cost is all than relatively low, and the cycle is fast, more It is important that this mould can be very good to be rapidly performed by mould modification according to the requirement of customer, greatly reduce and be produced into This, also improves production efficiency.

Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique Personage can understand the content of the utility model and be carried out, the scope of protection of the utility model can not be limited with this, All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in the scope of protection of the utility model It is interior.
