Preferably, the diameter of the rack gear angle ejector rod is not less than 25mm.
Preferably, the conduit diameter is not less than 6mm.
The technical effect of the utility model：It is long that a kind of rack gear ramp-roof structure of mold of the utility model can satisfy oblique top
Distance demoulding requirement, longest stroke can to 50mm, improve mold production stability, reduce die space, save mold at
This, is not limited to the influence of angles of product, reaches the high speed of mold, high-quality and stable operation with this.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of the rack gear ramp-roof structure of mold of the utility model embodiment.
Fig. 2 is a kind of another schematic diagram of the rack gear ramp-roof structure of mold of the utility model embodiment.
Schematic diagram when the first rack gear and the second rack gear that Fig. 3 is the utility model embodiment are engaged.
Specific embodiment
In the following, being further described in conjunction with substantive distinguishing features and advantage of the example to the utility model, but this is practical new
Type is not limited to listed embodiment.
As shown in Figure 1 to Figure 3, a kind of rack gear ramp-roof structure of mold of the present embodiment includes rack gear angle ejector rod 1, and rack gear is straight
Mandril 2, guide pad 3 and oblique top head 4, the rack gear angle ejector rod 1 pass through guide pad 3 and connect with oblique top head 4, and rack gear angle ejector rod 1 inclines
Tiltedly setting, 1 surface of rack gear angle ejector rod are equipped with the first rack gear 11.The guide pad 3 is arranged below oblique top head 4, and the rack gear is straight
Mandril 2 passes through guide pad 3, and the straight mandril 2 of rack gear is vertically arranged, and straight 2 surface of mandril of rack gear is equipped with the second rack gear 21, the second rack gear 21
It is engaged with the first rack gear 11.It can satisfy the need that some products demould wide-angle oblique top barb through the above technical solution
It asks, is mutually twisted and participates in synchronous ejection with rack gear angle ejector rod using the straight mandril of rack gear, oblique top is made to be detached from product back-off.Oblique top is fallen
The distance of button demoulding determines the angle of oblique top（Most very much not surpass 25 °）With the number of teeth of rack gear.
In the present embodiment, the contact range of the first rack gear 11 and the second rack gear 21 single rack gear when being engaged is straight not less than mandril
2/3rds of diameter, to guarantee the occlusion effect of two toothed racks.
In the present embodiment, the width of first rack gear 11 and the second rack gear 21 is 3mm to 5mm, fit clearance 0.1mm,
Rack gear interocclusal clearance is not necessarily to high-precision close fit, can there is the gap 0.1mm or so, is not necessarily to high-accuracy processing request, reduces difficult processing
Degree and cost.
In the present embodiment, the diameter range of the rack gear angle ejector rod 1 is 16mm to 30mm.The inclination of the rack gear angle ejector rod
