A kind of disconnected valve gated mold of twisted off type, it is related to pouring mould applications, and in particular to a kind of disconnected valve gated mold of twisted off type.Running channel is arranged in the middle part of mould crust, is provided with running channel center into cast gate；Type chamber is distributed in mould crust upper surface, cast gate one end connecting-type chamber, and the cast gate other end connects running channel by runner；Sprue distribution gets lodged in type chamber both ends, and limited block is arranged at four angles of mould crust；The cast gate is conical structure, and cast gate and type chamber junction are microcephaly, and sprue and runners junction is major part.After adopting the above technical scheme, the utility model have the beneficial effect that twist into two parts facilitate it is easy to operate, it is not necessary to it is easy to learn by external tool, reduce the labor intensity of operative employee to a certain extent, saved cost.Product is not only avoided because scissors is damaged, abrasive secondary injury also improves the product qualified rate of product.
Description
Technical field
The utility model relates to pour mould applications, and in particular to a kind of disconnected valve gated mold of twisted off type.
Background technique
Cast gate is also referred to as feed inlet, refers to one section of channel from runner to mold cavity, be running gate system middle section most
Small and shortest part.Molten metal enters entrance and the channel of casting mold when finger casting in metal casting.Usually refer to casting system
System.It acts on and is to make charging achieve the effect that acceleration using flow surface is tightened, high shear rate can make feed flow good；It is viscous
The temperature rise effect of stagnant heating also plays the role of promoting material temperature reduction viscosity.Cast gate solidifies sealing at first after molding, has anti-
Only charging flows back and avoids cavity pressure to decline the too fast function of making molded product generate systolic depression.It is then conveniently wiped out after molding
With separating flow tract system and type part.
Cast gate can be understood as last one of " door " that molten plastic enters type chamber by running gate system, be connection runner
With the feeding-passage of type chamber.There are two functions for its tool: first, control action is played to plastic melt inflow type chamber；Second, work as note
After blow pressure revocation, block type chamber flow backwards the plastics not yet cooled and solidified in type chamber will not.The selection of gate type depends on
The factors such as the requirement of products appearance, the restriction of size and shape and used plastics kind.Gate shape and size are to modeling
The influence of part quality is very big, and cast gate is the smallest size of part in runner middle section in most cases (except the cast gate of mainstream channel type
Outside), the ratio between sectional area of sectional area and runner is about 0.03-0.09, and cross sectional shape is mostly rectangle or circle, cast gate step
Long 1-1.5mm or so.
Hide into glue be on injection mold it is most common into one of glue mode, such into glue mode is hidden to inside product
Into glue, glue-feeder is cut off in ejecting product, it is possible to reduce is manually cut glue mouth the step, and will not influenced outside product
It sees.
Nowadays the contact area of cast gate and product on the market is all larger, needs repeatedly to cut and can divide using tool
From, and forceps inlet shearing pouring gate is used for a long time, and operative employee's hand can be made to knot, luck bubble, situations such as scissors is worn, sometimes
It can also lead to the problem of and make hammer-shears knife wound in one's hands and product accidentally.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of disconnected gating pattern of twisted off type is provided
Tool, it changes original pouring gate structure, optimizes its design, it can be enabled to be more easier to separate with product.
To achieve the above object, the utility model is using following technical scheme: it includes mould crust 1, type chamber 2, sprue
3, limited block 4, running channel 5, cast gate 6, into cast gate 7, runner 8, the setting of running channel 5 is provided with running channel 5 into cast gate 7 at 1 middle part of mould crust
Center；Type chamber 2 is distributed in 1 upper surface of mould crust, 6 one end connecting-type chamber 2 of cast gate, and 6 other end of cast gate connects running channel by runner 8
5；The distribution of sprue 3 gets lodged in 2 both ends of type chamber, and limited block 4 is arranged at 1 four angles of mould crust；The cast gate 6 is conical structure,
Cast gate 6 and 2 junction of type chamber are microcephaly, and cast gate 6 and 8 junction of runner are major part.
The junction of the cast gate 6 and type chamber 2 forms sharp angle, and is 8 minimum area position of runner at sharp angle.
Working principle of the utility model is: reducing the contact area of cast gate and type chamber, and utilize the cutting edge of a knife or a sword of conical contact point
Angle can fracture easily and separate product and runner.
After adopting the above technical scheme, the utility model have the beneficial effect that twist into two parts facilitate it is easy to operate, it is not necessary to by external work
Tool, it is easy to learn, reduce the labor intensity of operative employee to a certain extent, saves cost.Product is not only avoided because of scissors
It damages, abrasive secondary injury also improves the product qualified rate of product.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: mould crust 1, type chamber 2, sprue 3, limited block 4, running channel 5, cast gate 6, into cast gate 7, runner 8.
Specific embodiment
Referring to shown in Fig. 1, present embodiment the technical solution adopted is that: it include mould crust 1, type chamber 2, sprue 3,
Limited block 4, running channel 5, cast gate 6, into cast gate 7, runner 8, the setting of running channel 5 is provided in running channel 5 at 1 middle part of mould crust into cast gate 7
Centre；Type chamber 2 is distributed in 1 upper surface of mould crust, 6 one end connecting-type chamber 2 of cast gate, and 6 other end of cast gate connects running channel 5 by runner 8；
The distribution of sprue 3 gets lodged in 2 both ends of type chamber, and limited block 4 is arranged at 1 four angles of mould crust；The cast gate 6 is conical structure, is poured
Mouth 6 is microcephaly with 2 junction of type chamber, and cast gate 6 and 8 junction of runner are major part.
The junction of the cast gate 6 and type chamber 2 forms sharp angle, and is 8 minimum area position of runner at sharp angle.
After product stripping, operative employee's left hand holds product, and the right hand grasps 90 degree of runner rotating, realize product with into glue point
Fracture separation.
Working principle of the utility model is: reducing the contact area of cast gate and type chamber, and utilize the cutting edge of a knife or a sword of conical contact point
Angle can fracture easily and separate product and runner.
After adopting the above technical scheme, the utility model have the beneficial effect that twist into two parts facilitate it is easy to operate, it is not necessary to by external work
Tool, it is easy to learn, reduce the labor intensity of operative employee to a certain extent, saves cost.Product is not only avoided because of scissors
It damages, abrasive secondary injury also improves the product qualified rate of product.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the scope of the claims of the utility model.
