Abstract
The utility model discloses the seamless ejecting mechanism of a kind of hollow shape product, comprise fixed half and moving half, liftout plate is provided with bottom dynamic model, liftout plate is provided with release link, and dynamic model is provided with guide pillar, it is characterized in that, described release link upper end is all connected with moving die plate with guide pillar upper end, the rear end of moving die plate is provided with external coordination auxiliary cylinder, and the expansion link of external coordination auxiliary cylinder is connected with one end of connecting rod, and the other end of connecting rod is connected with push pedal.Die shape of the present utility model is little, injection moulding can produce the darker chamber of hollow that common die structure can not be shaping without the product ejecting vestige, while ensureing product appearance and size mould parts processing risk and cost relative also lower, mould structure is reliable, and injection molding machine tonnage is wider relative to common die structure choice.
Description
Technical field
The utility model relates to the seamless ejecting mechanism of a kind of hollow shape product, for dark chamber or surfaces externally and internally without the looking products ejecting vestige, belong to mould special construction technical field.
Background technology
The product surfaces externally and internally of some injection mouldings requires that higher permission ejects vestige, product design need be become the dark cavity shape of hollow by installing restriction by shape of product, general employing common die shaping structures, as shown in Figure 1 and Figure 2, open original mould 1., it is ejected by board, former liftout plate 4. drive former release link 3. to promote 2. former push pedal that 3. former release link go up rises, 5. original product is released.But if adopt this series products of common die shaping structures, cause die shape comparatively large, part processing charges is higher, injection moulding coupling board tonnage also needs corresponding increasing, causes many unnecessary costs to waste.
Summary of the invention
The technical problems to be solved in the utility model is: provide that a kind of profile is little, processing risk and the seamless ejecting mechanism of low, the reliable hollow shape product of cost, solve for the dark chamber of shaping hollow larger without the profile of the common die structure ejecting vestige product, part processing charges is higher, injection moulding coupling board tonnage also needs corresponding increasing, causes the problem of cost of idleness.
In order to solve the problems of the technologies described above, the technical solution of the utility model there is provided the seamless ejecting mechanism of a kind of hollow shape product, comprise fixed half and moving half, be provided with liftout plate bottom dynamic model, liftout plate is provided with release link, dynamic model is provided with guide pillar, it is characterized in that, described release link upper end is all connected with moving die plate with guide pillar upper end, and the rear end of moving die plate is provided with external coordination auxiliary cylinder, the expansion link of external coordination auxiliary cylinder is connected with one end of connecting rod, and the other end of connecting rod is connected with push pedal.
Preferably, described moving die plate is provided with core rod, and connecting rod is located in core rod, and push pedal is sheathed on outside core rod.
Preferably, described moving die plate is provided with at least 1 core rod.
Preferably, the top of described dynamic model is provided with lower die cavity, and cover half is provided with the upper die cavity matched with lower die cavity, and the side of upper die cavity is provided with the holddown groove that moving die plate upper end matches.
Die shape of the present utility model is little, injection moulding can produce the darker chamber of hollow that common die structure can not be shaping without the product ejecting vestige, while ensureing product appearance and size mould parts processing risk and cost relative also lower, mould structure is reliable, and injection molding machine tonnage is wider relative to common die structure choice.

Detailed description of the invention
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
The utility model is the seamless ejecting mechanism of a kind of hollow shape product, as shown in Figure 3-Figure 5, it comprises cover half 1 and dynamic model 10, liftout plate 2 is installed bottom dynamic model 10, liftout plate 2 is fixed with release link 3, dynamic model 10 has guide pillar 9, release link 3 upper end is all connected with moving die plate 4 with guide pillar 9 upper end, the rear end of moving die plate 4 is provided with external coordination auxiliary cylinder 5, and the expansion link of external coordination auxiliary cylinder 5 is connected with one end of connecting rod 6, and the other end of connecting rod 6 is connected with push pedal 7.Moving die plate 4 opposite side is provided with 2 core rod 4-1, connecting rod 6 is arranged between two core rod 4-1, and push pedal 7 is enclosed within outside core rod 4-1, and namely core rod 4-1 is through the hole that push pedal 7 matches with core rod 4-1.Lower die cavity 10-1 is arranged at the top of dynamic model 10, cover half 1 has the upper die cavity 1-1 matched with lower die cavity 10-1, the holddown groove 1-2 that the side of upper die cavity 1-1 has moving die plate 4 upper end to match.
As shown in Figure 3, Figure 4, by the utility model by compressing for product 8.Subsequently by mould die sinking, as shown in Figure 5, drive release link 3 to promote moving die plate 4 rising by liftout plate 2 and arrive qualifying bit postpone, external coordination auxiliary cylinder 5 promotes connecting rod 6, connecting rod 6 is fixed by screw and push pedal 7, together product 8 is released core rod 4-1 while push pedal 7 movement, thus reach the object of complete for injecting products ejection die.The stroke of external coordination auxiliary cylinder 5 determines the height of hollow dark chamber product herein.
