Abstract
The utility model discloses a kind of molding molds,Including mutually matched upper die and lower die,The gradient die joint for α is set between the upper die and lower die,The first sliding block is provided in the lower die,Second sliding block and third sliding block,It is provided with diamond shape core between first sliding block and the second sliding block and the second sliding block and the mating surface of third sliding block,And the upper and lower surface of sliding block is both provided with cinder ladle,By using the arrangement parting of three sliding blocks,Allowance can not only be reduced,Reduce the generation of stomata,And the first sliding block and the second sliding block and the core between the second sliding block and third sliding block are done into diamondwise,It prevents from generating back-off when demoulding,Simultaneously,It is fed using lower die,Larger die joint gradient is set,Keep runner more smooth,Also the generation of stomata can be effectively reduced,Sliding block top and bottom all open up cinder ladle,It is set fully to be vented,The qualification rate of product is effectively ensured.
Description
Technical field
The utility model is related to mould pressing technology field more particularly to a kind of molding molds.
Background technology
Mold, in industrial production to be molded, be blow molded, squeeze out, die casting or the methods of forging forming, smelting, punching press obtain
The various moulds and tool of required product, it mainly realizes adding for article shape by the change of physical state of the formed material
Work, mold make blank become the tool for the product for having specific shape and size under external force.Be widely used in punching, die forging,
The compression moulding of the products such as cold-heading, extruding, metallic sintered products compacting, compression casting and engineering plastics, rubber, ceramics or injection molding
In forming, the development level of mold production is the one of the important signs that of machine-building level, and procapsid is new-energy automobile
Shell on middle motor, it is very high to its sealing performance requirement, but in mold process, Chang Yin causes substandard products there are stomata
Rate is high, not only influences production efficiency, but also lead to excessively high manufacturing cost.
Utility model content
The utility model is directed to deficiency in the prior art, and allowance can be reduced by providing one kind, and stomata is avoided to generate
Molding mold.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals, a kind of molding mould
Have, including mutually matched upper die and lower die, the gradient die joint for α, the lower die are set between the upper die and lower die
On be provided with the first sliding block, the second sliding block and third sliding block, first sliding block and the second sliding block and the second sliding block and
Diamond shape core is provided between the mating surface of three sliding blocks, between the first sliding block and the mating surface of third sliding block between be provided with cylinder
Shape core, and it is both provided with cinder ladle positioned at the upper and lower surface of the first sliding block, the second sliding block and the second sliding block.
In said program, it is preferred that the bottom setting of the lower die has a cooling duct.
In said program, it is preferred that the charging runner of the lower die is provided with a plurality of.
In said program, it is preferred that the gradient α of the die joint is 30~35 °.
Compared with prior art, the utility model has the advantages that：By using the arrangement parting of three sliding blocks,
Allowance can be not only reduced, reduces the generation of stomata, and by the first sliding block and the second sliding block and be located at the second sliding block
Core between third sliding block does diamondwise, prevents from generating back-off when demoulding, meanwhile, it is fed, is arranged larger using lower die
Die joint gradient keeps runner more smooth, can also effectively reduce the generation of stomata, and sliding block top and bottom all open up cinder ladle, makes it fully
Exhaust, is effectively ensured the qualification rate of product.

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Fig. 1 to Fig. 6, a kind of molding mold, including mutually matched upper die and lower die 1 is arranged in the lower die
There is feed inlet 11, the gradient die joint 2 for α is set between the upper die and lower die 1, the first sliding block is provided in the lower die
12, the second sliding block 13 and third sliding block 14, first sliding block, 12 and second sliding block 13 and the second sliding block 13 and third are slided
Diamond shape core 3 is provided between the mating surface of block 14, between the first sliding block and the mating surface of third sliding block between be provided with cylinder
Shape core, and it is both provided with slag positioned at the upper and lower surface of the first sliding block 12, the second sliding block 13 and third sliding block 14
Packet 5.
The bottom setting of the lower die 1 has a cooling duct, the charging runner 15 of the lower die 1 to be provided with a plurality of, this reality
It applies and is provided with 3 in example, the gradient α of the die joint 4 is 30~35 °, most preferably 35 °.
The first sliding block 12 and the second sliding block 13 and the second sliding block 13 adjacent, and with gradient and third sliding block
It is provided with diamond shape core between 14, allowance can not only be reduced, while can also reduce stomata, and reduces the damage to cutter
Wound, molding compound flow to product by three plume roads of feed inlet point, and intermediate runner is introduced into die cavity, then passes through the runner of both sides
Full of cavity, and by the temperature in cooling control runner and cavity, optimum state is reached, meanwhile, expect into becoming a mandarin
The air and clout being discharged behind road are discharged by cinder ladle.
The scope of protection of the utility model includes but not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Subject to sharp claim, any replacement being readily apparent that those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
