Abstract
A kind of die casting of small-sized core convenient disassembly, the hole of this mould on forming part, comprise the die cavity of corresponding matching, main core fixed head, die cavity and main core arrange cylindricality fixed and moving model core inserts respectively, main core is also fitted with small-sized core, small-sized core outer end is connected with extension bar, the outer end of extension bar passes perpendicularly through through hole corresponding on core fixing plate and contacts with the detachable plugging plate in the deep gouge of main core fixed head outside and push against, and pulls down plugging plate and draws and pull and connect stock and can pull down small-sized core.The design science of this mould is reasonable, and make that the dismounting of small-sized core is more convenient, save trouble and labor, to enhance productivity, the extension bar of small-sized core is reusable simultaneously, saves cost.
Description
Technical field
The utility model relates to technical field of mold, particularly a kind of die casting of small-sized core convenient disassembly.
Background technology
Small-sized core can be subject to the effect of high temperature, high pressure in Die Casting, therefore, uses for a long time, small-sized core is easily out of shape, damages.Then need to change small-sized core as Die Casting will be continued.Shown in the method Fig. 1 of the fixing small-sized core 5 that existing a kind of die casting is common in producing, small-sized core 5 is being assemblied in main core 7, when dismantling small-sized core 5, need main core 7 small-sized core 5 could be disassembled from main core 7 after main core fixed head 8 takes apart, and, there is certain magnitude of interference between main core 7 and main core fixed head 8, not quick detachable, so when using this mould, the replacing dismounting of small-sized core 5 is very inconvenient, causes production efficiency low.
Summary of the invention
Goal of the invention of the present utility model is: for the deficiencies in the prior art, provides a kind of die casting of small-sized core convenient disassembly, makes small-sized core convenient disassembly, raise the efficiency.
The technical solution of the utility model is as follows: a kind of die casting of small-sized core convenient disassembly, the hole of this mould on forming part, comprise the die cavity of corresponding matching, main core fixed head, die cavity and main core arrange cylindricality fixed and moving model core inserts respectively, main core is also fitted with small-sized core, small-sized core outer end is connected with extension bar, the outer end of extension bar passes perpendicularly through through hole corresponding on core fixing plate and contacts with the detachable plugging plate in the deep gouge of main core fixed head outside and push against, and pulls down plugging plate and draws and pull and connect stock and can pull down small-sized core.
Further: plugging plate and main core fixed head are provided with corresponding screwed hole and insert for lock-screw.
Further: the outer end that extension bar contacts with plugging plate is provided with screwed hole, screw in for drawbench screw.
Further: small-sized core is threaded with extension bar to combine and assembles.
The beneficial effects of the utility model are:
1, small-sized core convenient disassembly
During dismounting small-sized core, first remove plugging plate, then screw is screwed in the screwed hole of small-sized core extension bar lower end, with the screw of drawbench drawing extension bar, small-sized core can be pulled out from main core, such structure makes that dismounting is more convenient, save trouble and labor, to enhance productivity.
2, extension bar recycling, reduces costs
The tail end of small-sized core connects extension bar, and replace small-sized core contact plugging plate with extension bar contact plugging plate, after small-sized core damages, only need change small-sized core and do not need to change extension bar, in contrast, extension bar is reusable, saves cost.
Accompanying drawing explanation
Fig. 1 is the profile of existing a kind of die casting
Fig. 2 is profile of the present utility model
Number in the figure is illustrated: 1-impression bolster; 2-fixed mold inserts; 3-die cavity; 4-die casting; 5-small-sized core; 6-dynamic mould core inserts; 7-main core; 8-main core fixed head; 9-small-sized core extension bar; 10-screw; 11-plugging plate.
Detailed description of the invention
It is shown in Figure 2 that (this profile is the sectional view of mould medium position, so do not show in the guide pillar figure of mould), a kind of die casting of small-sized core convenient disassembly, mainly comprise die cavity and the core of assembling in two pieces of fixed heads, die cavity and core are respectively arranged with fixed and moving model core inserts, and core is fitted with small-sized core, and existing mould compared by this mould, its small-sized core assembly structure has made significant change, specific as follows.
This mould has the fixed head of two pieces of corresponding matching, is divided into the impression bolster on top and the main core fixed head of bottom, and left side in fig. 2, two pieces of fixed head contact positions are reserved with runner, flow through for metal liquid.Assembly type chamber in impression bolster, assembling main core in main core fixed head.Fixed mold inserts and dynamic mould core inserts are separately fixed in die cavity 3 and main core 7, and fixed mold inserts and dynamic mould core inserts can be pulled down from die cavity 3 and main core 7 respectively; This fixed mold inserts and dynamic mould core inserts are not the parts that die casting has, and just need this inserts when diecast parts needing process macropore.Fixed mold inserts and dynamic mould core inserts are large, the inner little cylinder in outer end, are convenient to fixing assembling, and in fixed mold inserts and dynamic mould core inserts, end in contact pushes against.
Main core has vertical through hole, is fitted with small-sized core in through hole, the effect of small-sized core 5 is the apertures on forming part, and quantity and the size in its size, quantity and the hole in diecast parts are the same, arrange as required.Small-sized core is large, the inner little cylinder in outer end, and original be major diameter termination, small-sized core 5 lower end and smaller diameter end is one-body molded.And be processed with external screw thread near the outer end circumference of small-sized core in this mould, the die cavity that main core top and top are extended in small-sized core the inner holds out against, and the gap that die cavity, main core, small-sized core, fixed mold inserts and dynamic mould core inserts surround is the molding space (die casting 4 in Fig. 2 is car air-conditioner skull parts) of die casting.
In the prior art, relative fixed mold inserts and dynamic mould core inserts, small-sized core is after long-term use, easier deformed damaged, once small-sized core 5 damages, main core 7 also must be changed, cost is high, so connect extension bar to facilitate small-sized core dismounting and change in the outer end of every root small-sized core.Extension bar is cylindric, and extension bar is assemblied in through hole that main core fixed head is arranged; The inner of extension bar has internal thread hole, and screwed hole coordinates with the external screw thread on small-sized core, and small-sized core outer end screws in the inner screwed hole of extension bar and realizes threaded engagement connection; The screwed hole that the outer end end face of extension bar is also provided with indent screws in for drawbench.
Correspond in extension bar outer end on main core fixed head and be provided with deep gouge, deep gouge is square or circular etc., the plugging plate of form fit is provided with in deep gouge, corresponding screwed hole is provided with in the middle part of plugging plate and in main core fixed head deep gouge, for lock-screw plug-in mounting, make plugging plate realize detachable function, plugging plate pushes against support member as extension bar outer end, and restriction extension bar position makes extension bar be unlikely in main core fixed head to skid off.
The dismounting mode of small-sized core is specially: lock-screw of first dismantling removes plugging plate, then is screwed in by screw in the screwed hole of small-sized core extension bar lower end, finally, with the screw on this extension bar of drawbench drawing, small-sized core can be pulled out from main core.
