Abstract
The invention relates to a mould sprue bush which comprises a bush head part (1) and a bush tail part (2), wherein the center of the lower end face of the bush head part (1) is connected with the bush tail part (2), a circular truncated cone (3) is arranged on the upper end face of the bush head part (1), a semicircular groove (5) is formed in the center of the upper end face of the circular truncated cone (3) and is connected with an opening of a material hole (6), and the material hole (6) is formed in a center axial line of the bush head part (1) and the bush tail part (2). The mould sprue bush is relatively simple in structure and reasonable in design; a plurality of heat radiating grooves are formed in the outer surface of the sprue bush, thus a heat radiation effect of the sprue bush is increased, the service life of the sprue bush is prolonged, and the enterprise cost is lowered.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of die gate casing.
Background technology
Die gate casing is named again sprue bushing, Guan Zui, cast gate filling etc., to allow the plastic material of melting from the nozzle of injection machine, be injected into the runner part of mould inside, for connecting into the metal fittings of mould and injection machine, the plastic material of melting transfers heat to sprue bush while flowing through sprue bush, while therefore working, the plastic material that sprue bush is melted ceaselessly heats, sprue bush is easy to overheated cracking, the service life of sprue bush is short, need to often change, and has increased enterprise's manufacturing cost.
Summary of the invention
The objective of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of die gate casing, has increased the radiating effect of sprue bush, has extended the service life of sprue bush, has reduced entreprise cost.
The present invention is achieved through the following technical solutions: a kind of die gate casing, comprise cover head and cover afterbody, described pullover subordinate's end face center is connected with the cover afterbody, described cover head upper surface is provided with round platform, center, described round platform upper surface is provided with half slot, described half slot is connected with the aperture in material hole, and described material hole is arranged on the central axis of cover head and cover afterbody.
Further, described cover head periphery is taper surface, and described cover head periphery is provided with several round recesseds.
Further, described material hole is bellmouth, and aperture, lower end, described material hole is positioned at cover center, afterbody lower surface.
Further, described cover afterbody on the lower end face be provided with several grooves.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is relatively simple, reasonable in design, by the outer surface at sprue bush, some radiating grooves are set, increase the radiating effect of sprue bush, extended the service life of sprue bush, reduced entreprise cost.
The accompanying drawing explanation
Fig. 1 is the profile of a kind of die gate casing of the present invention;
Fig. 2 is the top view of a kind of die gate casing of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1-2, the present invention relates to a kind of die gate casing, comprise cover head 1 and cover afterbody 2, described cover head 1 center, lower surface is connected with cover afterbody 2, described cover head 1 upper surface is provided with round platform 3, described round platform 3 centers, upper surface are provided with half slot 5, described half slot 5 is connected with the aperture in material hole 6, described material hole 6 is arranged on the central axis of cover head 1 and cover afterbody 2, described cover head 1 periphery is taper surface, and described cover head 1 periphery is provided with several round recesseds 4, described material hole 6 is bellmouth, 6 apertures, lower end, described material hole are positioned at cover afterbody 2 centers, lower surface, described cover afterbody 2 end face on the lower is provided with several grooves 7.
In sum, structure of the present invention is relatively simple, reasonable in design, outer surface by the cover head 1 at sprue bush arranges some round recesseds 4, and the cover afterbody 2 on the lower end face several grooves 7 are set, increase the radiating effect of sprue bush, extended the service life of sprue bush, reduced entreprise cost.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
