Abstract
The invention provides a kind of injection moulding process of thin-wall product, the thin bone of injection pressure is decomposed in increase between the glue-feeder and thin-wall product of injection molding channel, it is molded the thin bone cavity for entering injection mold for glue-feeder of the melting glue through injection molding channel into glue order, subsequently into the thin-wall product chamber of injection mold, thin bone cavity is used to be molded thin bone, and thin-wall product chamber is used for forming thin-walled products.The beneficial effects of the invention are as follows：Injection pressure is decomposed by increasing thin bone between the glue-feeder and thin-wall product of injection molding channel, die life can be extended, it is ensured that product appearance.
Description
Technical field
The present invention relates to injection moulding process, more particularly to a kind of injection moulding process of thin-wall product.
Background technology
For commonly using the glue mode that clicks through on current mould, click-through glue typically directly puts two grades of appearances in product.With reference to
Accompanying drawing 1, clicks through glue and typically directly puts on product surface, product regional is directly diverted to from surface.In thin-wall product 2
Glue is walked during shaping difficult, the glue-feeder that injection pressure is excessively concentrated between injection molding channel 1 and thin-wall product 2 shortens the mould longevity
Life, and the appearance formation of die is impacted, easily cause product appearance surface bad.
The content of the invention
In order to solve the problems of the prior art, the bad thin-walled production in product appearance surface is improved the invention provides a kind of
The injection moulding process of product.
The invention provides a kind of injection moulding process of thin-wall product, increase between the glue-feeder and thin-wall product of injection molding channel
The thin bone of bonus point solution injection pressure, is molded the thin bone for entering injection mold for glue-feeder of the melting glue through injection molding channel into glue order
Chamber, subsequently into the thin-wall product chamber of injection mold, thin bone cavity is used to be molded thin bone, and thin-wall product chamber is used for forming thin-walled production
Product.
As a further improvement on the present invention, the thin bone is isosceles trapezoid flat board.
As a further improvement on the present invention, after thin-wall product shaping, thin bone is removed.
As a further improvement on the present invention, thin bone is removed by mouth of a river punching jig.
The beneficial effects of the invention are as follows：Decomposed by increasing thin bone between the glue-feeder and thin-wall product of injection molding channel
Injection pressure, can extend die life, it is ensured that product appearance.
Brief description of the drawings
Fig. 1 is that glue schematic diagram is entered in the injection of traditional thin-wall product.
Fig. 2 is a kind of schematic diagram of the injection moulding process of thin-wall product of the invention.
Embodiment
The invention will be further described for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 2 a kind of injection moulding process of thin-wall product, increases between the glue-feeder and thin-wall product 2 of injection molding channel 1
The thin bone 3 of bonus point solution injection pressure, it is that glue-feeder of the melting glue through injection molding channel 1 enters the thin of injection mold to be molded into glue order
Bone cavity, subsequently into the thin-wall product chamber of injection mold, thin bone cavity is used to be molded thin bone 3, and thin-wall product chamber is used for forming thin-walled
Product 1, after shaping, direct water nozzle punching smelting tool removes thin bone 3, machines, i.e., product can be allowed again by not increasing cost
Produce a desired effect.
As shown in Fig. 2 the thin bone 3 is isosceles trapezoid flat board.
A kind of injection moulding process for thin-wall product that the present invention is provided, passes through the glue-feeder in injection molding channel 1 and thin-wall product 2
Between increase thin bone 3, the mobility of thin glue product 2 can be improved, and decompose injection pressure, die life can be extended, it is ensured that
Product appearance.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
Claims (4)
