Specific embodiment

The utility model is further described with reference to the accompanying drawing.

As shown in Figs. 1-2, a kind of center submarine of automobile grille base mould is into system of pouring, including lower die 1 and upper mold 2, the lower die 1 is equipped with type core 3, and the upper mold 2 is equipped with type chamber 4 and injection molding channel 5, and the lower die 1 is equipped with Pitched roof mechanism 6, lower die 1 are equipped with the uphill running mouth 7 of connection injection molding channel 5, and the uphill running mouth 7 is connected to 6 side wall of pitched roof mechanism.

Melting charge enters in type chamber 4 through injection molding channel 5, and since uphill running mouth 7 is connected to injection molding channel 5, melting charge is advanced Enter into uphill running mouth 7, uphill running mouth fill after by being extended in type chamber 4 at the top of uphill running mouth, and type chamber 4 is filled, realize reversely into It pours.

As shown in connection with fig. 3, the structure setting is simple, without increasing extra structure, realizes reversely into pouring, to make to expect Handle 101 is located at 100 bottom of product, does not impact to product appearance, makes product outer wall that smooth shape be presented, and does not expect that handle cuts trace Mark.

As shown in connection with fig. 1, pitched roof mechanism 6 includes several Slanted ejecting components 8, several Slanted ejecting components 8 are along 1 center line of lower die It is symmetrical, uphill running mouth 7 have several and with Slanted ejecting component 8 correspond, injection molding channel 5 also have several and with uphill running mouth 7 It corresponds.

Preferred embodiment, Slanted ejecting component 8 has 6, and symmetrically distinguishes along 1 center line of lower die.More there are choosing, 1 center line of lower die Two sides are respectively equipped with 3 Slanted ejecting components 8 and the distribution triangular in shape of 3 Slanted ejecting components 8.

In the present embodiment, 3 Slanted ejecting components 8 are respectively set in the center line two sides of lower die 1, due to Slanted ejecting component 8 and uphill running Mouthfuls 7 corresponding, is equivalent to uphill running mouth 7 and is also symmetrically respectively set 3 respectively and along lower die center line along 1 center line of lower die, forms three Subscript enters, and melting charge is made to could quickly fill up type chamber, avoids lacking material.After formed product is cooling, three Slanted ejecting components 8 act on simultaneously, Make product two sides respectively by triangle stress, ejection process is steady, not will cause scratch to product.

Slanted ejecting component 8 includes the slanted kicking block 9 for being inserted into lower die 1 and being flexibly connected with lower die 1, and 9 top of slanted kicking block is under For 1 top shape of mould with fitting, slanted kicking block does not extend out 1 top of lower die, and 9 bottom of slanted kicking block is connected with angle ejector rod 10, angle ejector rod 10 On the same line, 10 bottom of angle ejector rod is connected with universal wheel 14 to the axial line of axial line and slanted kicking block 9, under universal wheel 14 is located at Outside mould 1.The material handle forming cavity 12 of connection uphill running mouth 7 is equipped on 9 side wall of slanted kicking block, material handle 101 has part to be located at material handle molding In chamber 12, in 9 ejecting product 100 of slanted kicking block, material handle 101 is made product surface stress point by the direct active force of slanted kicking block It dissipates, ejection process is more rapidly and steady, and the ejection trace of product inner wall mitigates.

Expect that 12 bottom of handle forming cavity is arc-shaped, material handle 101 is easy to deviate from from material handle forming cavity 12, and 7 bottom of uphill running mouth is in It is planar, expect to be easy to be detached from uphill running mouth 7 at the top of handle 101, material handle 101 is facilitated to eject.

As shown in connection with fig. 4,5 bottom of injection molding channel is equipped with injection nozzle 11 corresponding with 7 position of uphill running mouth, the injection nozzle Extend upper mold 2 and enter in type chamber 4 in 11 ends.In melting charge into when pouring, realization melting charge initially enters uphill running mouth 7, then Reversely diffuse into type chamber.

The cross-sectional area of injection nozzle 11 is become larger from upper mold 2 to the direction of lower die 1, makes into during pouring melting charge gradually Expand flow, melting charge is rapidly introduced into type chamber.

Upper mold 2 is equipped with cavity block 13, and injection molding channel 5 is connected to upper mold 2 and cavity block 13, cavity block 13 and upper mold 2 using being detachably connected, and easy to disassemble and replacement, the Slanted ejecting component 8 are corresponding with the position of cavity block 13.

The working principle of the utility model is:

As shown in connection with fig. 3, melting charge is flowed into injection nozzle 11 from injection molding channel 5, is directly injected into uphill running mouth 7, Material handle 101 is formed in uphill running mouth 7, after the material in uphill running mouth fills, melting charge is reversely diffused into type chamber 4, type chamber 4 is filled, Product 100 is formed after fitting-type core 3.

Angle ejector rod 10 pushes slanted kicking block 9, and slanted kicking block 9 drives material handle 101 and product 100 to be detached from the type core 3 of upper mold, realizes and produce Pint mould.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application.

Although more using lower die 1, upper mold 2, type core 3, type chamber 4, injection molding channel 5, pitched roof mechanism 6, uphill running mouth herein 7, Slanted ejecting component 8, slanted kicking block 9, angle ejector rod 10, injection nozzle 11, material handle forming cavity 12, cavity block 13, universal wheel 14, product 100, expect the terms such as handle 101, but it does not exclude the possibility of using other terms.The use of these items is only for more convenient Ground describes and explains the essence of the utility model, and being construed as any additional limitation all is and the utility model essence What mind was disagreed.
