Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of injection mould slide block speed change pulled core structure.
Background technology
Plastic injection mould is the instrument of producing plastic products, applies very extensive. in the design of injection mold, for the slide block of the long stroke of ask for something, normally adopt the structure of oil cylinder or long taper pin to realize the demoulding of slide block. cylinder structure: usually oil cylinder body is long-pending larger, usually need to strengthen for the installation of oil cylinder mold base, process in the above oil cylinder mounting groove, or additionally do a very large oil cylinder seat in mold base periphery, then, on the stand of oil cylinder being installed, greatly increased mould Outside Dimensions. inclined pin structure: adopting inclined pin structure in the little situation of normal ram travel is a more satisfactory mode, if but ram travel is larger, realize that the slide block demoulding just need to be designed to very wide-angle taper pin or very long taper pin design, the design maximum angle of taper pin can not exceed 22 degree under normal circumstances, length is no more than 10 times of diameter, if for the slide block demoulding of long stroke taper pin design very long or wide-angle very, taper pin can be easy to break, cause slide block to reset, will cause and hit mould aborning, mold damage part, have a strong impact on die life. above two schemes all can increase die cost greatly, and can make the Outside Dimensions of whole mould strengthen, and injection machine tonnage is also wanted corresponding increase, causes the waste of board, increases injection moulding cost.
Summary of the invention
The purpose of this utility model is to provide one can solve injection mold long-stroke slipper block loose core, and slide block core pulling structure simple in structure, easy for installation, that cost is lower, grow die life.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of slide block speed change pulled core structure of injection mold, comprises solid plate, moving platen, shifting block, slide block, guide pad, straight pin; Described solid plate is relative with moving platen and establish; The upper end of described shifting block is fixed on solid plate, the bottom of shifting block is located in moving platen, on the madial wall of shifting block, offer gathering sill, this gathering sill forms by driving slowly gathering sill and opening soon gathering sill linking, and the angle of opening slowly gathering sill and die sinking direction is less than the angle of opening soon gathering sill and die sinking direction; Described guide pad is fixed on moving platen, slide block is movably arranged on moving platen and slider bottom slips on guide pad, on the lateral wall of slide block, straight pin is installed, the gathering sill gap socket on this straight pin and shifting block madial wall also can move around along gathering sill.
Described shifting block has two, two shifting blocks are separately positioned on the both sides of slide block, on two lateral walls of slide block, straight pin is all installed, the straight pin on slide block two lateral walls respectively with two shifting block madial walls on gathering sill gap socket, make shifting block can drive slide block to move around.
The utility model also comprises stop screw and positioning bead; Described stop screw is arranged on moving platen and is positioned at the outer end of slide block motion track; Described positioning bead is arranged on moving platen and is positioned at the middle part of slide block motion track and can be socketed with the groove of slider bottom.
Described wear plate is arranged on solid plate, and leans with the outer end of slide block.
Adopt after such scheme, because the utility model comprises shifting block, slide block, guide pad, straight pin, shifting block is provided with the gathering sill of two sections of different gradients, this gathering sill can drive slide block to move around by the straight pin being fixed on slide block, realize opening at a slow speed, energetically and the quick unlatching in die sinking later stage of die sinking initial stage, met the requirement of loosing core of long stroke slider, save the parts such as oil cylinder in traditional structure, have advantages of simple in structure, easy for installation, cost is lower, die life is long.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Detailed description of the invention
As Figure 1-Figure 4, the utility model is a kind of slide block speed change pulled core structure of injection mold, comprises solid plate 1, moving platen 2, two shifting blocks 3, slide block 4, guide pad 5, two straight pins 6, stop screw 7, positioning bead 8, wear plate 9.
Described solid plate 1 is relative with moving platen 2 and establish. The upper end of two described shifting blocks 3 is all fixed on solid plate 1 and is separately positioned on the both sides of slide block, the bottom of shifting block 3 is located in moving platen 2, on the madial wall of shifting block 3, offer gathering sill 31, this gathering sill 31 forms by driving slowly gathering sill 311 and opening soon gathering sill 312 linkings, slowly drive gathering sill 311 and be less than with the angle of die sinking direction the angle of opening soon gathering sill 312 and die sinking direction, in the present embodiment, slowly driving gathering sill 311 is 23 ° (as shown in Figure 6) with the angle of die sinking direction, and driving soon gathering sill 312 is 41 ° (as shown in Figure 7) with the angle of die sinking direction.
Described guide pad 5 is fixed on moving platen 2, slide block 4 is movably arranged on moving platen 2, slip on guide pad 5 and taking guide pad 5 as guiding movement slide block 4 bottoms, on two lateral walls of slide block 4, straight pin 6 is all installed, straight pin 6 on 4 liang of lateral walls of slide block respectively with two shifting block 3 madial walls on gathering sill 31 gaps sockets and can move around along gathering sill 31, make shifting block 3 can drive slide block 4 to move around.
Described stop screw 7 is arranged on moving platen 2 and is positioned at the outer end of slide block 4 motion tracks, the effect of playing positioning sliding block 4 and moving terminal; Described positioning bead 8 is arranged on moving platen 2 and is positioned at the middle part of slide block 4 motion tracks, and positioning bead 8 can be socketed with the groove 41 of slide block 4 bottoms.
Described wear plate 9 is arranged on solid plate 1, and leans with the outer end of slide block 4.
Operation principle of the present utility model:
When die sinking, drive straight pin 6(as shown in Figure 5 by shifting block 3 gathering sills 31), thus band movable slider 4 moves. Described gathering sill 31 is made two angles, and the low-angle gathering sill 311 of opening slowly of leading portion ensures in die sinking, and slide block 4 can be not stuck due to the large package power of product; Back segment is because slide block 4 unclamps with respect to product, so back segment wide-angle drive soon gathering sill 312 to reduce the width of die sinking distance and shifting block 3, controlled die width, again can be under less die sinking distance, slide block 4 just can depart from product completely, and product is ejection device (as shown in Figure 3) smoothly. This structure processing is simple, easy for installation, has saved cost, can improve die life again, effectively controls mould Outside Dimensions size, reduces injection moulding cost.
Emphasis of the present utility model is just: the gathering sill on shifting block is divided into different two sections of angle.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
