Description
Technical field
Mould is the utility model is related to, it is more particularly to a kind of to demould stable injection mold.
Background technology
Plastic products have structural strength height, cost is low, processing is changeable, are widely used in life, production.Plastic products
Processing usually using arriving Shooting Technique, plastic grain is melting out in injection molding machine, is injected into the die cavity of mould,
The shape of die cavity is consistent with the shape and structure of processed product, and die cavity is opened after injection finishes, the product in die cavity
Abjection, completes injection molding.
Existing car light lampshade as shown in Figure 1, the one side edge a of car light lampshade can be past tilted, is producing this car light
When lampshade, die cavity is consistent with shape of product, therefore when injection finishes the demoulding, the product in die cavity is directly ejected,
During ejection, the edge of car light lampshade can be extruded toward turning up, and can so be deviate from, be easy to cause product and pull.
Utility model content
In view of the deficienciess of the prior art, demould stable injection mould the purpose of this utility model is to provide a kind of
Tool, product are not easy to pull when abjection.
The above-mentioned technical purpose of the utility model technical scheme is that：It is a kind of to demould stable note
Mould, including mould bases, are provided with upper die and lower die movable up and down on the mould bases, in the upper mold and lower die between set
The die cavity of converted products is useful for, the lower subplate being fixed on mould bases is provided with below the lower die, is provided with the lower die
The sliding block that can along inclined direction slide, one end of the sliding block are provided with the groove for forming introversion beveled edge outside product, institute
State the clamping of the sliding block other end and be provided with the slide for being fixedly connected with lower subplate and supplying sliding block lateral sliding, lower subplate is bonded with lower die
When, slider top is flushed with mould intracavity wall, and ejector retainner plate movable up and down, the thimble are provided with below the lower subplate
It is fixedly installed on plate and penetrates die cavity and for driving product mandril separated with die cavity.
Both through the above technical solutions, upper mold can keep the state of activity with lower die, so when injection
Close up and lower die is bonded with lower template, build complete die cavity, and then complete product can be molded by.On when demolished
Mould is first turned on, and can push lower die afterwards, is so subject to slide spacing during driving product to rise in lower die, sliding
Block is with respect to the oblique bottom offset of lower die so that groove is tilted with product and separated, and then is continuing to jack up by ejector retainner plate, you can pass through top
Pin causes product to be separated with die cavity, completes the demoulding.
After so product introversion beveled edge is deviate from inside, then mode that product is pushed to product stripping again can be effective
Protection product be not in during extraction damaged products situation, product deviate from when stable structure.
The utility model is further arranged to：The bottom plate that can be bonded with it, the bottom plate are provided with below the ejector retainner plate
