Abstract
An ejecting structure for mold runner, comprises the runner connected with mould by building mouth, builds between mouth and runner and is provided with crossing current road, and this crossing current road is provided with clearance position.Clearance position is curved, triangle or trapezoidal, and the opening direction of this clearance position is along ejecting direction.The center of clearance position is more than or equal to 10mm to the distance of building mouthful end and is less than or equal to 50mm.The length in crossing current road is 3.5 ~ 1.5 with the ratio of the length of building mouth.The utility model is by being provided with crossing current road building between mouth and runner, this crossing current road is provided with clearance position, when mouth will be built and runner ejects, certain space is had to avoid, can not extrude between plastics and plastics, can not fracture, last entirety is ejected, can not drop in mould, thus improve quality and the production efficiency of product; It has simple and reasonable and feature that is flexible operation.
Description
Technical field
The utility model relates to a kind of ejecting structure of mold runner.
Background technology
Existing plastic mould, in process of production, as shown in accompanying drawing 1-accompanying drawing 3, before die sinking, needs the runner 1 that removes for building and builds mouth 2.In order to remove runner 1 and build mouth 2, the common practice adopts ejecting mechanism to go to the position of pushing up runner 1 and building between mouth 2, but, when ejecting, due to runner 1 and build mouth 2 and do not dodge space, hard extruding between plastics and plastics can only be leaned on and go out, so, runner 1 and build and mouth 2 have extruding trace and easily fracture, is shown in accompanying drawing 3, and can disconnects at A place, thus cause the waste material after fractureing, in other words, can fall in mould to the waste material of building mouth 2 end from A, to such an extent as to affect quality and the production efficiency of product.
Utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, flexible operation, production efficiency are high, the ejecting structure of the mold runner of good product quality, to overcome weak point of the prior art.
The ejecting structure of a kind of mold runner designed by this object, comprises the runner connected with mould by building mouth, and its architectural feature builds between mouth and runner to be provided with crossing current road, and this crossing current road is provided with clearance position.
Further, described clearance position is curved, triangle or trapezoidal, and the opening direction of this clearance position is along ejecting direction.
Further, the center of described clearance position is more than or equal to 10mm to the distance of building mouthful end and is less than or equal to 50mm.
Further, the ratio of the radical length in the opening degree of depth of described clearance position and the crossing current road at its place is not more than 0.5.
Further, the length in described crossing current road is 3.5 ~ 1.5 with the ratio of the length of building mouth.
The utility model is by being provided with crossing current road building between mouth and runner, this crossing current road is provided with clearance position, when mouth will be built and runner ejects, certain space is had to avoid, can not extrude between plastics and plastics, can not fracture, last entirety is ejected, can not drop in mould, thus improve quality and the production efficiency of product.
Clearance position in the utility model is curved, triangle or trapezoidal, can be adapted to the crossing current road of different cross section, have larger adaptability.
In sum, the utility model have simple and reasonable, flexible operation, production efficiency are high and the feature of good product quality.

In figure: 1 is runner, and 2 for building mouth, 3 is crossing current road, and 4 is clearance position.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 4-Fig. 6, the ejecting structure of this mold runner, comprising the runner 1 connected with mould by building mouth 2, building between mouth 2 and runner 1 and being provided with the road 3 that flows over, this crossing current road 3 is provided with clearance position 4.
In the present embodiment, clearance position 4 is curved, triangle or trapezoidal, and the opening direction of this clearance position 4 is along ejecting direction.
The opening depth H 1 of clearance position 4 is not more than 0.5 with the ratio of the radical length H1 in the crossing current road 3 at its place.
The center of clearance position 4 is more than or equal to 10mm to the distance d building mouth 2 end and is less than or equal to 50mm.
The length L1 in crossing current road 3 is 3.5 ~ 1.5 with the ratio of the length L2 building mouth 2.
Through repeatedly testing, when the length L1 in the road 3 that flows over is 2.5 ~ 1.75 with the ratio of the length L2 building mouth 2, when the center of clearance position 4 is more than or equal to 12.5mm to the distance d building mouth 2 end and is less than or equal to 35mm, the effectiveness comparison ejected is good.
Result after ejecting, is shown in Fig. 6, and crossing current road 3 produces bending, crossing current road 3 and runner 1, builds mouth 2 and is connected.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
