Abstract
A kind of multi-cavity tubing precise injection mould throw-out collar, comprising shape is columniform installation locating surface, one end of this installation locating surface is connected with the outer conical surface of described throw-out collar, and the diameter of described installation locating surface is more than or equal to the diameter on the base of described outer conical surface, the other end convex of described installation locating surface is provided with bulge loop.Bulge loop of the present utility model is located at installs the bottom of locating surface, like this when clamping, as long as fix bulge loop, then can realize to internal conical surface, outer conical surface and installation locating surface processing by clamped one time, thus can ensure machining accuracy.
Description
Technical field
The utility model relates to a kind of multi-cavity tubing precise injection mould throw-out collar, belongs to mould auxiliary device technical field.
Background technology
Throw-out collar bears core in stable and support in multi-cavity tubing precise injection mould, shaping and sealing, exhaust, the vital tasks such as the demoulding, designing requirement must ensure that it installs locating surface (cylindrical see accompanying drawing 1) and internal conical surface for this reason, outer conical surface is coaxial, because the junction of installing between locating surface and outer conical surface has a circle bulge loop, like this at the processing excircles conical surface, when internal conical surface and installation locating surface, after cannot adopting a centering clamping, above-mentioned all three surface processing are put in place, process respectively after must being divided into twice centering clamping, so just be difficult to the requirement ensureing that it is mutually coaxial.
Summary of the invention
The utility model provides a kind of multi-cavity tubing precise injection mould throw-out collar.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multi-cavity tubing precise injection mould throw-out collar, comprising shape is columniform installation locating surface, one end of this installation locating surface is connected with the outer conical surface of described throw-out collar, and the diameter of described installation locating surface is more than or equal to the diameter on the base of described outer conical surface, the other end convex of described installation locating surface is provided with bulge loop.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Bulge loop of the present utility model is located at installs the bottom of locating surface, like this when clamping, as long as fix bulge loop, then can realize to internal conical surface, outer conical surface and installation locating surface processing by clamped one time, thus can ensure machining accuracy.
Accompanying drawing explanation
Accompanying drawing 1 is prior art schematic diagram.
Accompanying drawing 2 the utility model schematic diagram.
In above accompanying drawing: 1, outer conical surface; 2, locating surface is installed; 3, bulge loop; 4, inner conical surface.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, still all should drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
Embodiment: multi-cavity tubing precise injection mould throw-out collar
Shown in accompanying drawing 2, a kind of multi-cavity tubing precise injection mould throw-out collar, comprising shape is columniform installation locating surface 2, one end of this installation locating surface 2 is connected with the outer conical surface 1 of described throw-out collar, and the diameter of described installation locating surface 2 is greater than the diameter on the base of described outer conical surface 1, the other end convex of described installation locating surface 2 is provided with bulge loop 3.
Adding man-hour, with fixture clamping bulge loop 3, can process the installation locating surface 2 of throw-out collar, internal conical surface 4 and outer conical surface 1, realizing clamped one time can process three faces.So also can ensure the axiality in three faces.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
