Abstract
The utility model discloses a reset guide structure used for a die. The reset guide structure used for the die comprises a fixed model cavity, a top block, and a mandril. The top block is arranged at the top end of the mandril. The upper surface of the top block is provided with a positioning protruding part. The positioning protruding part is provided with an inclined plane in a protruding direction. A positioning groove which is matched with the positioning protruding part is formed in the fixed model cavity. By means of the design of the positioning protruding part and the positioning groove, guide and positioning functions can be achieved, and the phenomenon that displacement of the top block in the process of reset is avoided. Moreover, the reset guide structure used for the die is simple in structure, low in manufacture cost, and beneficial for wide use.
Description
Technical field
The utility model relates to automobile injection mold field, is specifically related to the reset guide structure for mould.
Background technology
Well-known, part mould (bumper mold that for example has back-off structure) is in producing automobile injecting products process, and most ejecting mechanism need synchronously eject.And when die sinking, ejecting mechanism is synchronizeed with die sinking and is carried out,, eject action and stop carrying out after certain distance when die sinking, and until the quick die sinking of mould to die sinking campaign end, ejecting action can proceed.And when matched moulds, resetting of ejecting mechanism synchronously carried out with matched moulds.But when ejecting distance when long, because the weight of jacking block is born by push rod fully, the situation of tenesmus appears easily, and in reseting procedure, dislocation easily appears in jacking block, can't proper reset, cause in the matched moulds process, jacking block and the extruding of cover half die cavity cause mould to scrap, and can't produce.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of reset guide structure for mould, by utilizing the guide-localization effect of positioning convex section and detent, thereby prevents from occurring the phenomenon of jacking block dislocation in reseting procedure.
For achieving the above object, the utility model adopts following technical scheme:
Be used for the reset guide structure of mould, comprise cover half die cavity, jacking block, push rod; Described jacking block is arranged on the upper end of push rod, and the upper surface of jacking block is provided with positioning convex section, and positioning convex section is provided with the inclined plane ejecting on direction; Described cover half die cavity is provided with the detent that is complementary with positioning convex section.
The angle of inclination on described inclined plane is 5 °.
The beneficial effects of the utility model are:
By adopting the design of positioning convex section and detent, can play the guide-localization effect, thereby prevent from occurring the phenomenon of jacking block dislocation in reseting procedure; And it is simple in structure, and processing cost is low, is conducive to be widely used.
Description of drawings
Fig. 1 is the schematic diagram that the utility model is used for the reset guide structure of mould;
Fig. 2 is the structural representation of the jacking block in the reset guide structure;
Wherein, 1, cover half die cavity; 2, jacking block; 21, positioning convex section; 3, push rod.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the reset guide structure that the utility model is used for mould is described further, so that clearerly understand the utility model technical thought required for protection.
As shown in Figure 1, 2, be used for the reset guide structure of mould for the utility model, comprise cover half die cavity 1, jacking block 2, push rod 3.And concrete, described push rod 3 can be set to straight push rod or angle ejector rod according to actual demand.Described jacking block 2 is arranged on the upper end of push rod 3, and the upper surface of jacking block 2 is provided with positioning convex section 21, and positioning convex section 21 is provided with the inclined plane ejecting on direction.And according to common practise, described positioning convex section 21 should be positioned on the non-glue plane of jacking block 2 upper surfaces.Cover half die cavity 1 is provided with the detent that is complementary with positioning convex section 21.By utilizing the guide-localization effect of positioning convex section 21 and detent, thereby prevent from occurring the phenomenon of jacking block 2 dislocation in reseting procedure, simultaneously, also can avoid cover half die cavity 1 to be clashed into, extend its service life.
Preferably, the angle of inclination on described inclined plane is 5 °.By adopting said structure, can be convenient to improve its performance, and positioning convex section 21 can be slipped in detent swimmingly.
When in reseting procedure, because the weight of jacking block 2 is born by push rod 3 fully, the situation of tenesmus easily appears, and rigidly connect when touching with cover half die cavity 1 when jacking block 2 moves to, the inclined plane of positioning convex section 21 contacts with the inclined plane of detent, and along with the carrying out of homing action, positioning convex section 21 slips in detent smoothly, can avoid jacking block 2 phenomenon of dislocation to occur.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
Claims (2)
