Description
Technical field
The invention belongs to injection mold field, more particularly, to a kind of uniform injection mold of cooling.
Background technology
Moulding generally use injection mold carries out injection molding, and the structure of mold is usually to have upper and lower two modules,
Injection mold cavity is formed among after the closed combination of upper die and lower die, due to adding in the plastic pellet of melting during cast, easily makes mold core mould
The malformations such as tool, it is therefore necessary to accelerate to cool down after casting complete and moulding is made faster to be molded.Also have that some are cold at present
But system is to set some through holes in mould inside, and then injection water is allowed to cool down in through-holes, but the cooling of this structure
Effect is bad, can be unevenly distributed cooling point, it is likely that deforms moulding, adds scrappage.
In addition, during moulding is molding, mold cooperates with lower mold, after moulding shaping, first unloads
Mold, then remove lower mold and get product.Since plastic cement products cannot be fully adhered to lower die during removal mold
Have side, be partly adhered on mold, product is caused to pull deformation.Solution method is to extend the cooling time of product at present,
Increase plastic cement products to male mould into the package power of shaped steel material, this method extends the molding cycle of product, reduces product
Production efficiency.
The content of the invention
In view of this, the present invention is directed to propose a kind of uniform injection mold of cooling, simple in structure, easy to use, injection
Accelerate when part is molded and it is uniformly cold goes, save the time, moulding is not in situation that product pulls deformation when removing, moulding
Quality is high, and scrappage is low, economizes on resources, and reduces production cost.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of uniform injection mold of cooling, including upper mold 1, lower die 2, cooling body 3 and moulding fixed mechanism 4, institute
The upper mold 1 and lower die 2 stated, which are matched somebody with somebody, is combined into intermediate injection mold cavity 5, has injection hole 11 among the upper mold 1；
The cooling body 3 includes being arranged on the pipe layers 31 inside upper mold 1, and the pipe layers 31 are centered around injection
5 surrounding of cavity is set, and the pipe layers 31 have the pipeline 32 interconnected, described 31 one end of pipe layers connection coolant
Input channel 33, other end connection coolant output tube road 34；
The moulding fixed mechanism 4, which includes being arranged on the injection outer wall of lower die 2, to be flared out from injection outer wall
Pawl 41 and control pawl 41 be opened and closed opener 42, the opener 42 is arranged on the inside of lower die 2, described
Opener 42 includes push rod 421, and 421 top of push rod is smooth section, and lower part is thread segment, the push rod 421
Multiple elastic bumps 422 are uniformly provided with close to top outer surface in smooth section, multiple elastic bumps 422 are outer with injection
Wall contact is set, and the thread segment of the push rod 421 is threadedly coupled with lower die 2, and one end of the thread segment of the push rod 421 is worn
Go out lower die 2 to be fixedly connected with rotating seat 423.
Further, 32 shape of pipeline is cylindric or flat-shaped.
Further, the moulding fixed mechanism 4 sets two groups, and is located at the both sides of injection mold cavity 5 respectively.
Further, the upper end of the pawl 41 and injection outer wall articulated connection.
Further, the pawl 41 at least sets two.
Compared with the prior art, a kind of uniform injection mold of cooling of the present invention has the advantage that：
A kind of uniform injection mold of cooling of the present invention, simple in structure, easy to use, moulding is accelerated when being molded
And it is uniformly cold go, save the time, moulding is not in situation that product pulls deformation when removing, and moulding quality is high, scraps
Rate is low, economizes on resources, and reduces production cost.
