Description
Technical field
The utility model is related to a kind of feeding structure, the feeding structures of the mold of specifically a kind of valve body.
Background technology
My company in the mold for making valve body, find product it is final it is cooling after, there are the integralities of product itself to lack
It falls into, phenomena such as shrinkage cavity defect occurs, qualification rate is too low, low in economic efficiency.
Utility model content
The technical issues of the utility model solves is to overcome the deficiencies in the prior art, and provide a kind of structure letter
It is single, ensure the feeding structure of the mold of product integrality.
Technical solution includes used by the application solves above-mentioned technical problem：A kind of feeding structure of mold, including phase
Mutually upper mold, the first sliding block, the second sliding block, sand core, forming blocks and the lower die of matching connection, lower die bottom surface is provided with the first cast
Mouthful, sand core is sleeved in forming blocks, it is characterized in that:The top of the lower die is provided with the lower die mold insert to match with lower die,
Its advantage is that：Lower die is divided into two parts to assemble, saves the process cost, is provided with above the lower die mold insert and places institute
The step for the forming blocks stated, its advantage is that：Lower die mold insert is set preferably to coordinate installation, the side of the lower die mold insert with forming blocks
Face is provided with gas vent, its advantage is that：The gas forming amount of sand core is removed by row of exhausting-gas hole, avoids internal generation after formed product
Hole is additionally provided with the second groove on the inside of first sliding block, the surrounding of second groove is provided with the second cast
Mouthful, its advantage is that：Big position thick to product carries out feeding, and wear rib is provided with above the lower die, its advantage is that：Make mold
Contact area reduces, and reduces open mold frictional force, reduces die wear..
Preferably, the upper mold lower part be provided with the matched upper mold mold insert of upper mold, its advantage is that：Upper mold is divided into two
Part assembles, and saves the process cost.
Preferably, the upper surface of the upper mold is provided with sand core riser, its advantage is that：By sand core riser, realize to zero
Part top thickness general goal carries out feeding, reduces shrinkage porosity defect of contraction cavity.
Preferably, the upper mold is provided with the first card slot, and the lower die is provided with the second card slot.
Preferably, the sand core is provided with and matched first groove of forming blocks outer profile institute.
The application has the characteristics that:It is simple in structure, it ensure that the integrality of product.

Specific implementation mode
It is described in further detail below in conjunction with the accompanying drawings and by embodiment to the application, following embodiment is to this Shen
Explanation please and the application is not limited to following embodiment.
Referring to Fig. 2 to Fig. 4, a kind of benefit of mold fills out structure, including is mutually matched the upper mold 1 of connection, the first sliding block 2,
Two sliding blocks 3 and lower die 4, upper mold 1 are provided with multiple sand core riser 11 above, and there are four symmetrical first for the both sides setting of upper mold 1
Card slot 12, the first card slot 12 match connection with the cylinder on top, and the lower part of upper mold 1 is provided with upper mold mold insert 13, upper mold 1 is divided into
Two parts assembling can reduce process costs and difficulty, it is cost-effective, also set up below lower die 4 there are two it is symmetrical second block
Slot 41, the second card slot 41 match connection with the pedestal of lower part, prevent mold from sliding, and the top of lower die 4 is provided with and 4 phase of lower die
The lower die mold insert 5 matched, lower die mold insert 5 are provided with the step 52 for placing forming blocks 6 above, and the side of lower die mold insert 5 is provided with more
A gas vent 51 is also cased with sand core 7 on the top of forming blocks 6, and sand core 7 is provided with and 6 outer profile of forming blocks institute matched first
Groove 71,4 bottom surface of lower die are also symmetrical arranged there are two the first sprue gate 43,
Referring to Fig. 4, the inside of the first sliding block 2 is additionally provided with the second groove 21, and the surrounding of the second groove 21 is provided with four
A second sprue gate 22 inserts molten metal from the second sprue gate 22, and feeding is carried out to some thick big positions.
Referring to Fig. 3, lower die 4 is also set up above there are four symmetrical wear rib 42, and the setting of wear rib 42 makes the first sliding block 2
Reduce with contact area, the second sliding block 3 and the contact area of lower die 4 of lower die 4, reduces open mold frictional force, reduce mold mill
Damage.
The explanation in relation to position relationships such as above, below, top, lower parts is in accordance with the attached drawing of embodiment in the application
Description.
Described in this specification above content is only to the application example explanation；Moreover, the application zero
The title that component is taken can also be different, done equivalent of all structure, feature and principles according to described in the application inventional idea or
Simple change is included in the protection domain of the application.
