Description
Technical field
The utility model is related to the equipment that plastic hollow is molded, specially a kind of plug of plastic hollow formation machine.
Background technology
For the hollow molding of plastics, need to shunt molten plastic fluid in the die cavity of shaping, plastic hollow
Would generally be symmetrically provided with the plug of shaping two runners of fish tail type for melt plastic liquid shunting, make at present
With the runner that more flow channel shape is gradually deep involute, the fluid of plastic molten melt is pressed by the runner of gradually deep involute
Contracting and mixing, so as to preferably spread out.
But, due to during the hollow molding of plastics, fluid mobility specific diameter vertically to mobility it is strong,
The flow direction of the gradually deep fluid that also cannot thoroughly change melting is made on runner direction, and fluid is by two fish tail type streams
After road shunting, the rate of flow of fluid for converging line position into two fish tail type runners is slower, and it converges line position after formed product
Thinner thickness, and along melt flow stream shunt before axis direction it is then thicker, cause the wall thickness of hollow molding plastic products not
Uniformly, the quality of product is influenceed, secondly because wall unevenness is even, the thickness of line position is converged for guarantee, the wave of material can be caused
Take.
Utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of plug for plastic hollow shaping,
Plastic molten melt fluid is shunted rapidly on plug, wall thickness uniform in shaping.
The utility model is to solve the technical scheme that uses of its technical problem：
A kind of plug of plastic hollow formation machine, including mounting seat, are connected with plug main body, the plug master in mounting seat
The surface of the middle and upper part of body is provided with a sprue, and the two ends of sprue are connected to a flow manifold, two flow manifolds
Respectively in the opposite both side surface of plug main body, the opening of the runner of the flow manifold gradually increases from top to down,
The both sides of the outlet end of the flow manifold cross with the both sides of the outlet end of another flow manifold be connected respectively, the shunting stream
Axially outward-dipping from top to down, the radius of curvature of the water passage surface of the flow manifold along plug of the water passage surface in road
Gradually increased to both sides from the middle part of the flow manifold.
Preferably, the expansion shape of the water passage surface of the flow manifold is fan ring.
Preferably, the cross section ovalize of the plug main body at two knit-lines of the outlet end of flow manifold, this is ellipse
The two-end-point of circular short-axis direction overlaps with two the two of the outlet end of flow manifold 11 joints.
The beneficial effects of the utility model are：A kind of plug for plastic hollow formation machine of the present utility model is provided with
Two flow manifolds of the fish tail type connected by sprue, the opening of the runner of the flow manifold gradually increases from top to down
Greatly, the both sides of the outlet end of flow manifold cross with the both sides of the outlet end of another flow manifold be connected respectively, the shunting stream
Axially outward-dipping from top to down, the radius of curvature of the water passage surface of the flow manifold along plug of the water passage surface in road
Gradually increased to both sides from the middle part of the flow manifold, the plastic liquid of melting when flow manifold shunts motion downwards, fluid
Scattered to both sides from the middle part of runner, because the middle part of flow manifold gradually increases to the radius of curvature of both sides, therefore plastics stream
Body branches to flow and the flow velocity increase of the both sides of flow manifold, it is therefore prevented that two flow manifolds of fish tail type converge line position
Molding thickness it is not enough so that the uniform wall thickness of hollow molded product.

Specific embodiment
Referring to Figures 1 and 2, a kind of plug of plastic hollow formation machine, including mounting seat 1, plug is connected with mounting seat 1
Main body 10, the surface of the middle and upper part of the plug main body 10 is provided with a sprue 12, and the two ends of sprue 12 are connected to
One flow manifold 11, two flow manifolds 11 are located in the opposite both side surface of plug main body 10 respectively, in the present embodiment,
Two flow manifolds 11 are symmetricly set in the both side surface of plug main body 10, and the opening of the runner of the flow manifold 11 is from upper
Down gradually increase, the surface of flow manifold 11 seamlessly transits, in the present embodiment, the water passage surface of the flow manifold 11
Expansion shape is fan ring, the both sides of the outlet end of the flow manifold 11 respectively with the both sides of the outlet end of another flow manifold 11
Cross connected, the axial direction along plug of the water passage surface of the flow manifold 11 is outward-dipping from top to down, the shunting stream
The radius of curvature of the water passage surface in road 11 is gradually increased from the middle part of the flow manifold 11 to both sides.
Reference picture 4, Fig. 4 is the schematic diagram of the expansion of the runner in plug main body 10, and sprue 12 is shaped as inverted U, U
The two ends of type runner connect the flow manifold 11 described in two respectively.
Reference picture 3, the cross section ovalize of the plug main body 10 at two knit-lines of the outlet end of flow manifold 11,
L as shown in the figure<D, the two-end-point of the oval short-axis direction and two the two of the outlet end of flow manifold 11 joint weights
Close, the two-end-point of the oval long axis direction is located on the center line of the annular flow manifold 11 of fan respectively, due to oval length
The radius of curvature of the endpoint location on direction of principal axis is minimum, and the radius of curvature of the endpoint location on oval short-axis direction is maximum, because
After the plastic liquid of this melting enters flow manifold 11 from sprue 10, the plastic liquid of melting along flow manifold 11 middle part
Spread to two ends so that the flow by the fluid at two knit-lines of flow manifold 11 increases, and flow velocity speeds, and solves original
The shaping relatively thin technical problem of wall thickness of fish tail type locations of structures.
A kind of plug for plastic hollow formation machine of the present utility model is provided with two and passes through what sprue 12 was connected
The flow manifold 11 of fish tail type, the opening of the runner of the flow manifold 11 gradually increases from top to down, and flow manifold 11 goes out
The both sides at liquid end cross with the both sides of the outlet end of another flow manifold 11 be connected respectively, the water passage surface of the flow manifold 11
Along plug axially it is outward-dipping from top to down, the radius of curvature of the water passage surface of the flow manifold 11 is flowed by the shunting
The middle part in road 11 gradually increases to both sides, and, in the shunting motion downwards of flow manifold 11, fluid is from runner for the plastic liquid of melting
Middle part scattered to both sides, because the middle part of flow manifold 11 gradually increases to the radius of curvature of both sides, therefore plastic liquid point
It flow to flow and the flow velocity increase of the both sides of flow manifold 11, it is therefore prevented that two flow manifolds of fish tail type 11 converge line position
Molding thickness it is not enough so that the uniform wall thickness of hollow molded product, while reducing the waste of material.
Preferred embodiments of the present utility model are the foregoing is only, as long as realizing the utility model with essentially identical means
The technical scheme of purpose is belonged within protection domain of the present utility model.
