Abstract
A kind of spliced spot pouring mouth nested structure, including upper mold insert and lower mold insert, its main points is that upper mold insert gate shape is provided in upper mold insert, lower mold insert gate shape is provided in lower mold insert, the upper mold insert lower end is provided with forked tail platform, and the lower mold insert upper end is provided with dovetail groove, and the forked tail platform that upper mold insert lower end is set is installed in the dovetail groove of lower mold insert upper end, forked tail platform and dovetail groove are fitted close, the perforation corresponding with lower mold insert gate shape of upper mold insert gate shape.The utility model greatly reduces the workload of electro-discharge machining, to reduce process time, and the quality of workpiece is made to be more readily available guarantee.
Description
Technical field
The utility model relates to field of die equipment, in particular to a kind of structure of spliced hole irrigation muzzle.
Background technique
In mold production, spot pouring mouth is a kind of common gate form, based on easy to process, maintenance easy to repair etc. because
Element, we would generally be in the position making point sprue bush of mold spot pouring mouth.But because of shape of product, the limit of the factors such as mould structure
System, the size of hole irrigation muzzle can be made long sometimes, and it is still not very convenient to process, and the efficiency of electro-discharge machining is greatly lower than line
The means with other machinery processing are cut, product quality is not easy to guarantee, process time is too long, and cost is too high.
Utility model content
The purpose of this utility model is greatly reduced in view of the above-mentioned problems, providing a kind of workload for making electro-discharge machining, from
And reduce process time, and the quality of workpiece is made to be more readily available the spliced spot pouring mouth nested structure of one kind of guarantee.
The technical solution adopted is that:
A kind of spliced spot pouring mouth nested structure, including upper mold insert and lower mold insert, main points are provided in upper mold insert
Upper mold insert gate shape is provided with lower mold insert gate shape in lower mold insert, and the upper mold insert lower end is provided with forked tail platform, institute
The lower mold insert upper end stated is provided with dovetail groove, and the forked tail platform that upper mold insert lower end is set is installed in the dovetail groove of lower mold insert upper end, swallow
Tail platform and dovetail groove are fitted close, the perforation corresponding with lower mold insert gate shape of upper mold insert gate shape.
The utility model uses separate structure, and the gate shape inside lower mold insert, can be directly by passing with regard to relatively simple
The electro-discharge machining of system is changed to linear cutter.Upper mold insert gate shape then continues using electro-discharge machining, but the length of upper mold insert
Only 25mm, the electro-discharge machining amount of sprue bush entire in this way is just by 100mm scope change as shown in Figure 1 in order to as shown in Figure 2
25mm. wire cutting processing efficiency and processing quality all greatly be better than electro-discharge machining, can thus shorten the duration,
The easier quality for guaranteeing workpiece again.
The utility model greatly reduces the workload of electro-discharge machining, to reduce process time, and makes the matter of workpiece
Amount is more readily available guarantee.
Detailed description of the invention
Fig. 1 is an embodiment of the present invention structural schematic diagram.
Fig. 2 is upper mold insert and lower mold insert decomposition texture schematic diagram.
Fig. 3 is upper mold insert and lower mold insert exploded perspective structural schematic diagram.
Specific embodiment
A kind of spliced spot pouring mouth nested structure, including upper mold insert 1 and lower mold insert 2, main points are arranged in upper mold insert 1
There is upper mold insert gate shape 5, lower mold insert gate shape 6 is provided in lower mold insert 2,1 lower end of upper mold insert is provided with swallow
Tail platform 3,2 upper end of lower mold insert are provided with dovetail groove 4, and the forked tail platform 3 that upper 1 lower end of mold insert is set is installed in lower 2 upper end of mold insert
Dovetail groove 4 in, forked tail platform 3 and dovetail groove 4 are fitted close, and upper mold insert gate shape 5 is corresponding with lower mold insert gate shape 6 to be passed through
It is logical.
