Abstract
The utility model discloses a many back -offs mold insert subassembly goes out mould with moving houding, including fixed die plate, cover half benevolence, movable mould board, movable mould benevolence, roof, mold insert subassembly, thimble, fixed die plate and movable mould board relative and establish, the merciful and peaceful movable mould benevolence of cover half fixed mounting respectively is equipped with the die cavity at fixed die plate and movable mould inboard between the merciful and peaceful movable mould benevolence of cover half, the upper end of mold insert subassembly stretch into the die cavity, mold insert subassembly upper portion has a cascaded surface, the bottom surface keep (shenglvehao)at a certain distance away of this cascaded surface and movable mould benevolence, what movable mould board and roof and mold insert subassembly lower extreme were passed to the lower part of mold insert subassembly hangs the bench top by the bottom surface at the roof, thimble upper end stretch into the die cavity after passing the movable mould board, the lower extreme of thimble is fixed on the roof. Because the utility model discloses mold insert subassembly upper portion has a cascaded surface, and when the inside back -off of product was ejecting, when the product back -off can drive the mold insert subassembly and pushes up the certain distance, the cascaded surface on mold insert subassembly upper portion can restrict the mold insert subassembly and continue to follow the thimble and continue ejecting product.
Description
Technical field
This utility model relates to a kind of injection mold, particularly relates to a kind of many back-offs mold insert assembly with dynamic rear ejection die.
Background technology
Plastics injection mould is the instrument producing plastic, and application is widely.The structure of the plastic product on existing market becomes increasingly complex, many plastics all have back-off, as shown in Figure 1, this product 10 has two back-offs 101,102, thus it requires mould also have can be molded the structure of this back-off and have a kind of can be intact take out insert structure what mould was extracted out from back-off.
Summary of the invention
The purpose of this utility model is that the many back-offs mold insert assembly providing a kind of demoulding simple, highly reliable is with dynamic rear ejection die.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of many back-offs mold insert assembly with ejection die after dynamic, including solid plate, fixed mold core, moving platen, mavable module core, top board, mold insert assembly, thimble；Described solid plate is relative with moving platen and sets, and fixed mold core and mavable module core are respectively and fixedly installed in solid plate and moving platen, are provided with die cavity between fixed mold core and mavable module core；Die cavity is stretched in the upper end of described mold insert assembly, and mold insert assembly top has cascaded surface, interval, the bottom surface of this cascaded surface and mavable module core 5-20 millimeter, and the bottom of mold insert assembly acts against the bottom surface of top board through the hanging platform of moving platen and top board and mold insert assembly lower end；Die cavity is stretched into after moving platen in described thimble upper end, and the lower end of thimble is fixed on top board.
Described mold insert assembly is made up of mold insert, mold insert seat and hanging platform；The lower end of described mold insert is fixed and is nested with in the upper end of mold insert seat and forms cascaded surface between mold insert and mold insert seat, and the bottom surface of this cascaded surface and mavable module core is spaced 10 millimeters, and hanging platform is fixed in the lower end of mold insert seat.
After using such scheme, owing to this utility model mold insert assembly top has cascaded surface, when interiors of products back-off ejects, when product back-off can drive mold insert assembly top to certain distance (such as: 10 millimeters), the cascaded surface on mold insert assembly top can limit mold insert assembly to be continued to follow thimble continuation ejecting product, when top board resets, the hanging platform on mold insert assembly can make mold insert assembly return in situ.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the axonometric drawing of product；
Fig. 2 is matched moulds state diagram of the present utility model；
Fig. 3 is die opening state figure of the present utility model.
Detailed description of the invention
As shown in Figure 2 and Figure 3, this utility model is a kind of many back-offs mold insert assembly with ejection die after dynamic, including solid plate 1, fixed mold core 2, moving platen 3, mavable module core 4, top board 5, mold insert assembly 6, thimble 7.
Described solid plate 1 is relative with moving platen 3 and sets, and fixed mold core 2 and mavable module core 4 are respectively and fixedly installed in solid plate 1 and moving platen 3, are provided with die cavity between fixed mold core 2 and mavable module core 4.
Described mold insert assembly 6 is made up of mold insert 61, mold insert seat 62 and hanging platform 63.Die cavity is stretched in the upper end of described mold insert 61, its end constitutes the back-off 101(of product 10 as shown in Figure 1), the lower end of mold insert 61 is fixed and is nested with in the upper end of mold insert seat 62 and forms cascaded surface 612 between mold insert 61 and mold insert seat 62, the bottom surface of this cascaded surface 612 and mavable module core 3 is spaced 10 millimeters, and hanging platform 63 is fixed in the lower end of mold insert seat 62 by screw.The bottom of mold insert seat 62 acts against the bottom surface of top board 5 through moving platen 3 and top board 5 and hanging platform 63；Die cavity is stretched into after moving platen 3 in described thimble 7 upper end, and the lower end of thimble 7 is fixed on top board 5.
Operation principle of the present utility model:
When the internal back-off 101 of product 10 ejects, when product 10 back-off 101 can drive the distance that mold insert assembly 6 pushes up 10 millimeters, the cascaded surface 612 on mold insert assembly 6 top can limit mold insert assembly 6 to be continued to follow thimble 7 and continues up ejecting product 10.When top board 5 resets, the hanging platform 63 on mold insert assembly 6 can make mold insert assembly 6 return in situ.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
