Abstract

The utility model discloses a kind of core assembly, comprising: fuse and the fuse being enclosed within outside fuse cover, and described fuse back segment is provided with fuse overcoat; Described fuse lid tail end is fixed on the back segment of described fuse, between described fuse lid and the end face of described fuse overcoat, fits; Described fuse leading portion diameter is less than back segment diameter; Described fuse back segment center has main inner chamber, is provided with shunting inner chamber in the fuse of main lumen downstream, and shunting inner chamber is communicated with described main inner chamber; Between described fuse leading portion excircle and described fuse lid inwall, be provided with water conservancy diversion gap.By the way, the utility model can reduce fuse temperature leak, and fuse range of temperature is little, is difficult for producing cold burden, good product quality.

Description

A kind of core assembly
Technical field
The utility model relates to TOP-TIP field, particularly relates to a kind of core assembly.
Background technology
TOP-TIP is the important component part in injection mold production equipment, utilizes heating and temperature controlled principle, makes the flow path portion of mould keep molten condition.As shown in Figure 1, in prior art, core assembly comprises fuse 1, fuse lid 2 and fuse overcoat 3, fuse covers 2 rear ends and is fixed on fuse 1, between fuse lid 2 and fuse 1, be provided with empty avoiding gap 9, fuse covers 2 front ends and is provided with the envelope material boss 10 with fuse close contact, envelope material boss 10 is by 9 sealings of empty avoiding gap, the material that prevents molten condition flows in empty avoiding gap 9, fuse lid 2 all contacts with fuse 1 front and back end, and contact-making surface is large, the water jacket 7 being enclosed within outside core assembly can reduce fuse temperature, the position contacting with water jacket will produce cold burden, easy flow liner under product upper reaches, product easily turns white.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of core assembly, can reduce fuse temperature leak, and fuse range of temperature is little, good product quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of core assembly is provided, comprises: fuse and the fuse being enclosed within outside fuse cover, and described fuse back segment is provided with fuse overcoat; Described fuse lid tail end is fixed on the back segment of described fuse, between described fuse lid and the end face of described fuse overcoat, fits; Described fuse leading portion diameter is less than back segment diameter; Described fuse back segment center has main inner chamber, is provided with shunting inner chamber in the fuse of main lumen downstream, and shunting inner chamber is communicated with described main inner chamber; Between described fuse leading portion excircle and described fuse lid inwall, be provided with water conservancy diversion gap.
Preferably, described shunting inner chamber is arranged on the joint of described fuse lid and described fuse, and described shunting inner chamber is communicated with described water conservancy diversion gap.
Preferably, described fuse lid front opening is the infundibulate of outwards opening.
The beneficial effects of the utility model are: the utility model can make fuse variations in temperature little, improve injecting products quality.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of core assembly in prior art;
Fig. 2 is the sectional structure schematic diagram of a kind of core assembly of the utility model;
Fig. 3 be shown in the structural representation of a kind of core assembly while coordinating with water jacket;
In accompanying drawing, the mark of each parts is as follows: 1, fuse; 2, fuse lid; 3, fuse overcoat; 4, main inner chamber; 5, shunting inner chamber; 6, water conservancy diversion gap; 7, water jacket; 8, Jiao Kou; 9, empty avoiding gap; 10, envelope material boss.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 2 and Fig. 3, the utility model embodiment comprises:
A core assembly, is shown in Fig. 2, comprising: fuse 1 and the fuse being enclosed within outside fuse 1 cover 2, and described fuse 1 back segment is provided with fuse overcoat 3; Described fuse covers on the back segment that 2 tail ends are fixed on described fuse 1, between described fuse lid 2 and the end face of described fuse overcoat 3, fits tightly, and described fuse covers 2 front openings and is the infundibulate of outwards opening, and is beneficial to the outflow of material; Described fuse 1 leading portion diameter is less than back segment diameter, and fuse 1 top is tapered; Described fuse 1 back segment center has main inner chamber 4, is provided with shunting inner chamber 5 in the fuse 1 in main inner chamber 4 downstreams, and shunting inner chamber 5 is communicated with described main inner chamber 4; Described fuse 1 leading portion excircle and described fuse cover between 2 inwalls and are provided with water conservancy diversion gap, and described shunting inner chamber 5 is arranged on the joint of described fuse lid 2 and described fuse 1, and described shunting inner chamber 5 is communicated with described water conservancy diversion gap 6.As shown in Figure 3, water jacket 7 is enclosed within on core assembly, and fuse covers 2 front ends and water jacket 7 is connected and fixed, and fuse 1 top reaches glue mouth 8 centers of water jacket 7; The material of molten condition is diverted to shunting inner chamber 5 from main inner chamber 4, and flow out from the glue mouth 8 of water jacket 7 in the water conservancy diversion gap 6 of flowing through.In the utility model, fuse lid 2 only has a place of back segment to contact with fuse 1, and it is hot mouth temperature highest point that fuse 1 covers 2 contact points with fuse, and fuse 1 variations in temperature is little, is difficult for producing flow liner on product, and product can not turn white.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
