Description
Technical field
The present invention relates to injection molding apparatus field, in particular to a kind of fascia injection mould with buffering road
Tool.
Background technique
Mold is modern industry, the especially industry such as automobile, radio, aviation, electrical equipment and electrical, instrument, instrument, daily necessities
Essential technological equipment.The flow passage system of injection mold refers to stream of the melt since the nozzle of injector until type chamber
Dynamic channel.In injection moulding process, plastic melt enters mold cavity, flow passage system by flow passage system, that is, nozzle, runner and cast gate
The quality of design has very important influence to the quality of moulding and productivity effect.Common flow passage system by sprue, point
Runner, cast gate, cold slug well and five part of type chamber composition.
The pouring gate structure of existing injection mold is in injection moulding process, when plastic melt passes through runner, plastic melt
Typically directly by being directly molded after sprue and runner.Traditional injection mold is deposited in injection molding
In the technological deficiency that can not be calibrated.
In the implementation of the present invention, the inventor finds that the existing technology has at least the following problems:
The flow velocity of one side fluid is very big, and the pressure of fluid also can be bigger, finally may leave and to develop and print on product
Trace, especially when producing some transparent injected-moulded workpiece, these are developed and printed will be more obvious, not only influences product
Quality and appearance can also bring the worry of quality and leakage aspect to consumer.Upper mold can not be accurately aimed at down when falling
Mould.
Summary of the invention
In order to solve problems in the prior art, the embodiment of the invention provides a kind of fascia use with buffering road
Injection mold.The technical solution is as follows:
The embodiment of the invention provides a kind of fascia injection mold with buffering road, the vapour with buffering road
Vehicle instrument board injection mold includes upper mold, the lower die to match with the upper mold, through the upper mold and the lower die
Pouring gate structure；
The upper mold is made of punch-pin and upper plate, and the bottom of the punch-pin is equipped with positioning column；The punch-pin is equipped with type core, described
Type core is equipped with aperture, and the aperture is connected to pouring gate structure；
The lower die is made of cavity plate and lower plate, and the upper surface of the cavity plate is equipped with the positioning matched with the positioning column
Hole；Position corresponding with the type core is equipped with type chamber on the cavity plate；
The pouring gate structure includes sprue and runner, and buffering road is equipped between the sprue and the runner.
The buffering road is arc-shaped buffering road.
The buffering road is that L shape buffers road.
The positioning column is two and two or more.
Technical solution provided in an embodiment of the present invention has the benefit that
It is matched by positioning column and positioning hole, the accuracy of upper die and lower die cooperation can be effectively improved；By in sprue and
Increase buffering road between runner, after fluid enters buffering road, can be very good the flow velocity and pressure that reduce fluid, reduce
Transparent injection-molded parts develop and print the probability of trace appearance, simple and practical in structure, improve production efficiency.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.
Fig. 1 is the structural schematic diagram of upper mold provided in an embodiment of the present invention；
Fig. 2 is the structural schematic diagram of lower die provided in an embodiment of the present invention；
Fig. 3 is the structural schematic diagram of pouring gate structure provided in an embodiment of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The embodiment of the invention provides a kind of fascia injection molds with buffering road, referring to Fig. 1, the tool
The fascia injection mold for having buffering road include upper mold 1, the lower die 2 to match with upper mold 1, through upper mold 1 and under
The pouring gate structure 3 of mould 2.
Specifically, upper mold 1 is made of punch-pin 11 and upper plate 12, and the top of upper plate 12 is equipped with pouring gate structure 3, punch-pin 11
Bottom be equipped with multiple positioning columns 110, punch-pin 11 is equipped with type core 111, and type core 111 is equipped with aperture, and aperture and pouring gate structure 3 connect
It is logical.
Specifically, referring to fig. 2, lower die 2 is made of cavity plate 21 and lower plate 22, and the upper surface of cavity plate 21 is equipped with and positioning
The location hole 210 that column 110 matches, position corresponding with type core 111 is equipped with type chamber 211 on cavity plate 21.
Specifically, referring to Fig. 3, pouring gate structure 3 includes sprue 31 and runner 32, between sprue 31 and runner 32
Equipped with buffering road 33；Buffering road 33 is arc-shaped or L shape.
When fluid enters runner by cast gate, runner has first passed around sprue, is then entered by buffering road
It to after runner, enters eventually into type chamber, can be very good the flow velocity and pressure of reduction fluid in centre in this way, reduce
Bright moulding develops and prints the probability of trace appearance, simple and practical in structure, improves production efficiency.
Technical solution provided in an embodiment of the present invention has the benefit that
It is matched by positioning column and positioning hole, the accuracy of upper die and lower die cooperation can be effectively improved；By in sprue and
Increase buffering road between runner, after fluid enters buffering road, can be very good the flow velocity and pressure that reduce fluid, reduce
Transparent injection-molded parts develop and print the probability of trace appearance, simple and practical in structure, improve production efficiency.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
