Abstract
The utility model relates to the mould field, in particular to a core-pulling delaying structure of a sliding block of a mould. The core-pulling delaying structure is characterized by comprising the sliding block and a shifting block, wherein a core portion is arranged in front of the sliding block, and a sliding way is arranged in the sliding block. The shifting block is provided with a first shifting block part which is arranged along the mould opening direction and a second shifting block part which is arranged obliquely relative to the mould opening direction. The first shifting block part and the second shifting block part form a whole, the shifting block is arranged in the sliding way, and the first shifting block part is connected with a fixed mould. When the fixed mould is opened, the shifting block slides for a certain distance along the mould opening direction relative to the sliding way, and the second shifting block part abuts against the inner wall of the sliding way to enable driving force perpendicular to the extending direction of the second shifting block part to be exerted on the sliding block. By means of the core-pulling delaying structure of the sliding block, manufacture cost of the mould is reduced, production efficiency is improved, the forming period is shortened, and accident potential is eliminated.
Description
Technical field
The utility model relates to mould applications, and particularly structure is extracted in a kind of delay of slide block core of mould out.
Background technology
What existing mould structure adopted is the oil hydraulic cylinder pulled core structure, the dovetail groove in addition at take-up housing 3 backs, slide block back slide bar 2 catches on take-up housing 3,2 of slide bars are fixed on the oil hydraulic cylinder sliding plunger 1, oil hydraulic cylinder seat 4 is fixed on the moving platen with left and right sides screw 5, oil hydraulic cylinder then is fixed on the oil hydraulic cylinder seat 4 with four microscler screws, after these indispensable parts are fixed, two oil pipes of oil hydraulic cylinder side being respectively the turnover oil pipe is connected on the injection molding machine again, after assembling is finished, also need to be separately fixed at moving platen at four support columns of the ground of mould bases side assembling, on the solid plate, by the front and back order of injection molding machine control oil hydraulic cylinder motion.When the injection machine injection mo(u)lding, promote to move back the moulding oil pipe mould slide block is extracted out; When the mould matched moulds, namely the moving oil pipe of crossed belt puts slide block movement in place, can finish like this slipper block loose core motion of whole mould.This mould usable floor area is large, has virtually increased a lot of manufacturing costs and production cost, and needs complicated control system, and inconvenience is installed, poor stability, and pollute working environment.
The utility model content

Preferably, the delay of described slide block core is extracted out in the structure, described slideway includes with described the first shifting block partly to have the first slideway part of identical bearing of trend and partly has the second slideway part of identical bearing of trend with described the second shifting block, and described the first slideway part and the second slideway partly communicate with each other, described the first shifting block partly is positioned at described the first slideway part, described the second shifting block partly is positioned at described the second slideway part, have the space between described the second slideway part and described the second shifting block part, and this space is consistent with described certain distance at the height of die sinking direction.
Preferably, the delay of described slide block core is extracted out in the structure, also comprises:
The shovel base, it is connected with described cover half, and described shovel base is connected with described slide block, and is obliquely installed for relative described die sinking direction with the contact-making surface of described slide block.
Preferably, the delay of described slide block core is extracted out in the structure, the contact-making surface incline direction angle of described shovel base and described slide block greater than with the incline direction angle of described the second shifting block part.
Preferably, the delay of described slide block core is extracted out in the structure, and described the first shifting block partly is vertical the setting, and described the second shifting block partly is obliquely installed for relatively described vertical direction.
Preferably, the delay of described slide block core is extracted out in the structure, and described installation of slide track is in the middle part of described slide block.
Slider delay described in the utility model is extracted out in the structure, during the mould die sinking, dynamic model retreats, extract fixed mold out the slide block core fully relatively first, when moving to certain distance, described the second shifting block is partly conflicted to the inwall of described slideway, so that described slide block is subject to the driving force perpendicular to the bearing of trend of described the second shifting block part, under the driving of this active force, thereby described slide block is done laterally horizontal movement along described slideway and is made the slide block core break away from back-off.Because the utility model does not use oil hydraulic cylinder to drive the extraction campaign of slide block core, has therefore eliminated accident potential, is conducive to the protection of environment.

The specific embodiment
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do simple the introduction to needed accompanying drawing in embodiment or the description of the Prior Art.
The utility model provides a kind of delay of slide block core to extract structure out, comprising:
Shifting block 8, described shifting block has the second shifting block part 10 that is obliquely installed along the first shifting block part 9 of die sinking direction setting and relatively described die sinking direction, and described the first shifting block part and described the second shifting block partly consist of an integral body, described shifting block is positioned at described slideway, and described the first shifting block part is connected with described cover half, when described cover half die sinking, the relatively described slideway of described shifting block occurs along the slip of the certain distance of described die sinking direction, described the second shifting block is partly conflicted to the inwall of described slideway, so that described slide block is subject to the driving force perpendicular to the bearing of trend of described the second shifting block part.
The delay of described slide block core is extracted out in the structure, described slideway includes with described the first shifting block partly to have the first slideway part of identical bearing of trend and partly has the second slideway part of identical bearing of trend with described the second shifting block, and described the first slideway part and the second slideway partly communicate with each other, described the first shifting block partly is positioned at described the first slideway part, described the second shifting block partly is positioned at described the second slideway part, have the space between described the second slideway part and described the second shifting block part, and this space is consistent with described certain distance at the height of die sinking direction.
The delay of described slide block core is extracted out in the structure, also comprises:
