Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As Figure 1-Figure 4, a kind of mold is present embodiments provided, the injecting products such as box cover can be formed.Mold includes
Front template and rear pattern plate are provided with front cavity 3 in front template, are provided with rear cavity 4 in rear pattern plate, front cavity 3 and rear cavity 4 it
Between form the type chambers 2 of multiple shaped articles, each type chamber 2 is connected to injecting glue runner.By the way that multiple type chambers are arranged in mold
2, multiple products can be successively formed, the shaping efficiency of product is improved.
In the present embodiment, mold further includes ox horn into plastic structure 1, to avoid forming cast gate on the surface of shaped article,
So that it is guaranteed that injecting products is overall beautiful.
As shown in Figure 1-Figure 3, ox horn is formed between the front cavity 3 in mold and rear cavity 4 into plastic structure 1.Wherein, ox
The chamber structure that angle is formed between front cavity 3 and rear cavity 4 into plastic structure 1, for convenience of introducing, with injection molding in Fig. 1-Fig. 3
When chamber structure in fill moulding material shape show introduce.
Ox horn includes the sprue 11 being connected to injecting glue runner into plastic structure 1 and multiple shuntings for being connected to sprue 11
Road 12, each runner 12 is corresponding to be communicated with an ox horn runner 13, and each correspondence of ox horn runner 13 is connected to a type chamber 2.
By ox horn moulding material can be provided for multiple type chambers 2 simultaneously into plastic structure 1.In the present embodiment, in mold there are four settings
Type chamber 2, there are four ox horn runner 13 is correspondingly arranged.
In the present embodiment, ox horn runner 13 is curved arced flow path, and moulding material enters type chamber into plastic structure 1 by ox horn
When in 2, the gradient of arced flow path is smaller, by arc-shaped transition, can slow down the Fluid pressure at Jiao Kou, Jiao Kou is separated with product
When, Jiao Kou cutting is cleaner, can effectively control the generation of material bits, to reduce the frequency of cleaning mold, improves production efficiency.
Wherein, Jiao Kou is type chamber 2 and ox horn into the junction of plastic structure 1.
For the pressure for further decreasing the position Jiao Kou, multiple ox horn runners 13 can be symmetricly set on the two of sprue 11
Side, multiple ox horn runners 13 can play the role of partial pressure, reduce the injection pressure in each ox horn runner 13, advantageously reduce material
The generation of bits.In the present embodiment, there are four the settings of runner 12, and it is two groups that four runners 12, which are divided to, every group of two runners
12 are symmetrical arranged, and two groups of runners 12 are symmetrical arranged.Corresponding, it is two groups that four ox horn runners 13, which are divided to, every group of two oxen
Angular flux road 13 is symmetrical arranged, and two groups of ox horn runners 13 are symmetrical arranged.Ox horn runner 13 is symmetrical arranged, and is reducing each ox horn stream
On pressure-based in road 13, the pressure size of balanced each ox horn runner 13, so that one-time formed product quality is more equal
It is even.
As shown in Figures 2 and 3, the outlet end of ox horn runner 13 is the hierarchic structure 131 that area of section is sequentially reduced.Ox horn
The end of runner 13 is the hierarchic structure 131 that is sequentially reduced of area of section, on the one hand, area of section reduces stepwise, can be to avoid
Runner size abrupt change and cause plastic material pressure oscillation larger, the smallest type chamber for partially protruding into mold of area of section
In 2, Jiao Kou is easier to cut off after being conducive to molding, and can guarantee that notch is neat, is not likely to produce clast；Another aspect area of section
Injecting glue momentum can also be increased under the premise of the moulding material flowed through is inconvenient by reducing stepwise, avoided injecting glue from leaving a blank, guaranteed product
Quality.
To make the smooth variations such as area of section and Fluid pressure between each ladder, arc surface mistake between adjacent ladder
It crosses, the connectivity part of runner 12 and ox horn flowing can also pass through arc surface transition.Junction is also advantageous using arc surface transition
In demoulding, the difficulty of demoulding is reduced.
As shown in figure 4, mold further includes thimble 5, and groove, needle are additionally provided on the bottom wall of sprue 11 for convenience of demoulding
It is arranged in rear cavity 4, top is protruded into groove.After injecting moulding material, plastic material forms and thimble 5 in groove
The ejection part 14 of cooperation.It is opened after formed product, thimble 5 moves upwards, and pushes ejection part 14, the ox solidified in ox horn runner 13
Corner structure stress deformation simultaneously disconnects at Jiao Kou, so that ox horn be ejected into ox horn structure molding in plastic structure 1.
Tip portion for convenience of the ox horn structure after solidification deforms in ox horn runner 13, so that it is at Jiao Kou
It disconnects, the protrusion 121 of annular is provided on the bottom wall of sprue 11, around ejection part 14 to make ox horn structure in ejection part 14
Periphery forms the depressed area of annular, so that ox horn structure be made to be easier to deform in ejection process, it is disconnected to be on the one hand conducive to Jiao Kou
Open, be easier the tip portion of ox horn structure by being detached from ox horn runner 13, thus avoid tip portion with
Molding product contact, scratches product.
The protrusion 121 of annular can be set multiple, and the quantity of annular protrusion 121 is more, and ox horn structure is more easily deformed,
The intensity of ox horn structure is also smaller simultaneously, and ox horn structure is also more easy to break in ejection process, for this purpose, the protrusion of annular
121 quantity should not be excessive, and specific quantity may be set according to actual conditions.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
