Abstract

The utility model proposes a kind of mould structure solving compression mod die sinking casting deformation, comprise left slider, right slide block, push rod and moving die insert, moving die insert has boss, boss fastens the side of foundry goods 10%; When foundry goods carry out side loose core time, wherein 90% side is shaping by slide block, and 10% side is shaping by moving die insert.When loosing core while compression mod die sinking, shaping that fraction foundry goods of moving die insert also stops in moving die insert motionless, and foundry goods can not produce distortion because there being this to support.After action of loosing core completes, foundry goods is steadily ejected by push rod, and now foundry goods only bears the steady ejecting force of push rod, and ejects and can not have an impact to the total of foundry goods, therefore foundry goods entirety can not deform.

Description

A kind of mould structure solving compression mod die sinking casting deformation

Technical field

The utility model relates to compression mod technical field, is specially a kind of mould structure solving compression mod die sinking casting deformation.

Background technology

During compression casting, the frame structure foundry goods often having part special is because the requirement of structure, and mould will divide with die sinking to vertical part foundry goods in shaping frame structural casting by slipper block loose core.

As shown in Figure 1, according to current design of Die Casting, when mould die sinking on die casting machine (slide block is loosed core simultaneously), push rod (4) eject foundry goods, because foundry goods is being loosed core on direction, the shape that foundry goods is vertical with die sinking direction is all loosed core shaping by slide block (1), (3), add that moving die insert (2) does not form cast shape loosing core on direction, process of loosing core medium casting is stressed and cannot support fixing along direction of loosing core, foundry goods often will produce distortion along direction of loosing core, cause casting dimension uniformity poor, affect product quality and payment.

Summary of the invention

Limitting by current die casting mold structure, when foundry goods is all loosed core by slide block is shaping in a direction, foundry goods can be out of shape in different the producing in compression mod die sinking (slide block is loosed core) simultaneously of degree.For this reason, the utility model proposes a kind of mould structure solving compression mod die sinking casting deformation, needed all to change into most shaping by slide block by slide block is shaping in a direction by foundry goods, fraction is shaping by moving die insert, thus the problem on deformation that solution foundry goods produces because of compression mod die sinking.

The technical solution of the utility model is:

Described a kind of mould structure solving compression mod die sinking casting deformation, comprise left slider, right slide block, push rod and moving die insert, it is characterized in that: moving die insert has boss, boss fastens the side of foundry goods 10%; When foundry goods carry out side loose core time, wherein 90% side is shaping by slide block, and 10% side is shaping by moving die insert.

Beneficial effect

In Die Casting, owing to being force the reasons such as die sinking under high pressure, high speed lower charging type and the effect of compression mod at die casting machine, casting deformation is the quality problems often occurred.The present invention mainly solves in Die Casting, and compression mod die sinking causes the distortion of foundry goods, and the plane that slipper block loose core is shaping and the shaping plane verticality of moving die insert can reach 0.1, is less than 0.3 of former drawing regulation.Foundry goods ejects steadily, reliable in quality meets user's requirement.For reduction casting wasted product, saving is melted, the waste of the energy consumption of die casting operation, equipment loss and human resources, increases economic efficiency and has important function.

Wherein: 1, left slider, the moving die insert of 2 existing compression mods, 3, right slide block, 4, push rod, 5, the moving die insert of the utility model compression mod.

Detailed description of the invention

This utility model is the compression mod for solving the special frame structure foundry goods of part, and when die sinking, foundry goods produces texturing quality problem, and the new die casting mold structure of one proposed.The foundry goods of this utility model application needs to loose core in three directions, wherein in left and right horizontal both direction, foundry goods divides two parts shaping along the shape in direction of loosing core by this structure, wherein left slider (1), right slide block (3) respectively the left and right level of mould casting to loose core both direction major part shape, the fraction shape of moving die insert (5) shaping both direction respectively.When loosing core while compression mod die sinking, shaping that fraction foundry goods of moving die insert (5) also stops in moving die insert motionless, and foundry goods can not produce distortion because there being this to support.After action of loosing core completes, foundry goods is steadily ejected by push rod (4), and now foundry goods only bears the steady ejecting force of push rod (4), and ejects and can not have an impact to the total of foundry goods, therefore foundry goods entirety can not deform, and finally takes out foundry goods.Then next working cycles is entered.

Key point of the present utility model be exactly when the Die-Casting mould that structure is special need carry out side loose core time, wherein 90% side is shaping by slide block, and 10% side is shaping by moving die insert.Foundry goods can not produce distortion when loosing core in process.

As shown in Figure 2, in Die Casting, after compression mod matched moulds, type is filled in injection, then while compression mod die sinking, left slider [1] slides left and looses core, and right slide block [3] slides to the right and looses core, and the shape of foundry goods two sides about 10% still rests in moving die insert [5] motionless.Though therefore be subject to left and right both direction during foundry goods die sinking and loose core the external force caused, because the shape of foundry goods two sides 10% rests in moving die insert [5] motionless, foundry goods is had and supports and can not distortion be produced.After compression mod die sinking, push rod [4] steadily ejects rear taking-up foundry goods.Then next working cycles is entered.

Claims

1. solve a mould structure for compression mod die sinking casting deformation, comprise left slider, right slide block, push rod and moving die insert, it is characterized in that: moving die insert has boss, boss fastens the side of foundry goods 10%; When foundry goods carry out side loose core time, wherein 90% side is shaping by slide block, and 10% side is shaping by moving die insert.
