Abstract
The invention discloses male die oil cylinder thimble die internal cutting, which comprises an upper fixing plate, a lower fixing plate, a female die plate arranged on the upper fixing plate and a male die plate arranged on the lower fixing plate, wherein a core insert for molding products is formed on the male die plate, and a cavity insert adaptive with the core insert is formed on the female die plate; a die cavity for the injection molding of injection molding pieces and a stub bar groove communicated with the die cavity are formed on the core insert; a thimble passing through the core insert and an ejector for driving the thimble to move are arranged on the male die plate; and the thimble is arranged between the stub bar groove and the die cavity. In the male die oil cylinder thimble die internal cutting, the thimble is driven to move up and down by an oil cylinder, so that a glue opening in a feed opening groove is cut off before die sinking; and in the aspect of product appearance, the surface of the glue opening is smoother than that of artificial cutting, and rough edges are difficult to generate, the efficiency is high, the time of labor and material cutting is saved, and the rough edges of the products are prevented. The male die oil cylinder thimble die internal cutting is easy to operate and convenient to use, improves the quality and production efficiency of the products, and fulfills the aim of cutting residual stub bars off automatically.
Description
?
Technical field
What the present invention relates to is a kind of moulding mould, and what be specifically related to is a kind of male model oil cylinder thimble mould inscribe of excising the unnecessary mouth of a river of moulding material.
Background technology
Present mould has a lot of types, wherein a kind of mould is that the manufacturing plastic material is the moulding mould, after injection moulding finishes, because when flat Jiao Kou ejects, on moulding, can be mouth of a river material by residual stub bar, need this moment manpower to fracture to separate and be easy to generate burr after artificial the separation, often need manpower to carry out secondary operations, easily form burr, waste time and energy, increased cost, and complicated operation, inefficiency, and the removal of mouth of a river material can not effectively guarantee the balance of all angles, influences the quality and the production efficiency of product.
Summary of the invention
At the deficiency that exists on the prior art, the present invention seeks to be to provide a kind of simple to operate, the efficient height can cut off the male model oil cylinder thimble mould inscribe of residual stub bar automatically, and the quality and the production efficiency of product is provided.
To achieve these goals, the present invention realizes by the following technical solutions:
Male model oil cylinder thimble mould inscribe comprises upper mounted plate, bottom plate and is installed in the caster of upper mounted plate and is installed in male model plate on the bottom plate; It is characterized in that, on described male model plate, be provided with the male model benevolence that is used for injecting products, described caster is provided with and the suitable mother module core of male model benevolence, described male model benevolence is provided with the mold cavity of injection mo(u)lding moulding and is communicated with the stub bar groove of mold cavity, described male model plate is provided with thimble that passes male model benevolence and the ejector that drives the thimble operation, described thimble is arranged between stub bar groove and the mold cavity, cuts off the residual stub bar of finished product by thimble.
According to described male model oil cylinder thimble mould inscribe, wherein, also be fixed with the mould pin between described bottom plate and the male model plate, described male model plate connects firmly with bottom plate mutually by the mould pin.
According to described male model oil cylinder thimble mould inscribe, wherein, what described ejector adopted is oil cylinder.
According to described male model oil cylinder thimble mould inscribe, wherein, the piston rod of described oil cylinder is connected with jacking block, one end of described thimble is fixed on the jacking block, the other end of described thimble passes male model benevolence, is arranged between stub bar groove and the mold cavity, is used to cut off the stub bar that finished product remains in the stub bar groove.
The beneficial effect that the present invention is compared with prior art had is:
The present invention drives thimble by oil cylinder
OnFollowing operation, thereby will expect that before die sinking the Jiao Kou in mouthful groove cuts off, the smooth surface that Jiao Kou more manually cuts in product appearance is difficult for producing burr, and the efficient height, saved the time artificial and that cut material, avoided the generation of product burr, it is simple to operate, and is easy to use, provide high the quality and the production efficiency of product, reached the purpose of the residual stub bar of automatic cut-out.

The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment:
Referring to Fig. 1 and Fig. 3, present embodiment male model oil cylinder thimble mould inscribe, it comprises upper mounted plate 10, bottom plate 50, mould pin 40, caster 20 and male model plate 30; This male model plate 30 is fixed on the bottom plate 50 by mould pin 40, fixing caster 20 on upper mounted plate 10, the male model benevolence 31 that is used for injecting products is installed on the male model plate 30, in male model benevolence 31, be processed with injection molding product and be the mold cavity 311 of moulding and stub bar groove 312(referring to Fig. 4), this stub bar groove 312 is connected with mold cavity 311, by stub bar groove 312 injection raw material is flow in the mold cavity 311.
In the present embodiment, in the male model plate 30 below male model benevolence 31 jacking block 33 is installed, on jacking block 33, be equipped with and pass male model benevolence 31, and thimble 34 moving up and down, the ejector that drives thimble 33 operations also is installed below jacking block 33, this ejector is arranged between the mould pin 40 ejector by on the lower surface of specializing in screw and being fixed on male model plate 30.What the ejector of present embodiment adopted is oil cylinder 32, and the piston rod of this oil cylinder 32 connects firmly mutually with jacking block 33.Thimble 34 is arranged between stub bar groove 312 and the mold cavity 311, the one end is fixed on the jacking block 33, its other end passes male model benevolence 31, be used to cut off residual stub bar 61(that finished product remains in stub bar groove 312 referring to Fig. 4), residual stub bar 61 is disconnected mutually with shaped article 60, is the purpose of residual stub bar 61 thereby reach fast shut-off product Jiao Kou.
The oil cylinder 32 of this enforcement can be controlled its operation by controller or other control device, makes it can realize cutting off automatically product Jiao Kou.
