Description

A kind of die core rod automatic plug mechanism
Technical field
It the utility model is related to technical field of mold, more particularly to a kind of die core rod automatic plug mechanism.
Background technology
In injection mold technology, there is the structures such as hole, groove, after this results in formed product, hole in many product surfaces It is difficult to be stripped at groove, in order to ensure that die table is stripped, the structure design difficulty of mould is significantly increased.In order to ensure the demoulding saves Power, generally with product hole slot at core bar is set, open up a through hole on core rod, insertion core bar, the inner of core bar in through hole It is corresponding with product hole slot to stretch into die cavity, then core bar is positioned, after product injection molding, extracts core bar, is then stripped. Due to being required for manually inserting core bar, positioning core bar before being molded every time, injection back bucket needs artificial extraction core bar, manually plugs core Bar workload is big, and the injection production efficiency for also resulting in product reduces.
The content of the invention
The utility model is in order to solve the above-mentioned problems in the prior art, there is provided can be automatically inserted into before one kind injection Core bar and position, be molded after can extract automatically core bar be easy to the demoulding die core rod automatic plug mechanism.
To achieve these goals, the utility model adopts the following technical scheme that:
A kind of die core rod automatic plug mechanism, is arranged on solid plate, is provided with core bar hole in solid plate, core bar is set in hole There is core bar, the right side of the solid plate is provided with oil cylinder fixing base, oil cylinder, the oil cylinder are fixed with the right side of the oil cylinder fixing base Shaft end be provided with sliding block, the left end of the sliding block is provided with T-shaped skewed slot, and the axis in the core bar hole is vertical with T-shaped skewed slot, the core The outer end of bar is provided with the bulge loop being slidably matched with T-shaped skewed slot, and the axis of the oil cylinder and the axis of core bar form obtuse angle.Mould closes After mould, the shaft end of oil cylinder is stretched out, and sliding block by the fully-inserted core bar hole of core bar, stretch into die cavity, then carries out by the inner of core bar It is molded, after formed product, the axle retraction of oil cylinder, extracts core bar when sliding block is displaced outwardly, the inner of core bar separates with product, from And be easy to be stripped, greatly improve product injection molding efficiency.
Preferably, be provided with contiguous block between the shaft end of oil cylinder and sliding block, the right-hand member of the sliding block be provided with two it is parallel Slide bar, the contiguous block is provided with corresponds the slide opening being slidably connected with slide bar, and the right-hand member of slide bar is provided with spacing ring, solid plate The upper cavity that is arranged right below positioned at contiguous block, described cavity is interior to be provided with limited block, is set between limited block and the bottom surface of cavity There is stage clip, the end face center of the limited block is provided with skewed slot, and the bottom of the contiguous block is provided with limited block and avoids breach, limited block The center for avoiding breach is provided with the boss coordinated with skewed slot;When in the fully-inserted core bar hole of core bar, limited block enters limited block Avoid in breach, the left surface of limited block abuts with the right flank of sliding block.After core bar insertion, sliding block is limited by the abutting of limited block Position, core bar can not move during injection, and injection precision is high, and injection pressure is not transferred to oil cylinder, oil cylinder is played a protective role;Need When extracting core bar, the shaft end retraction of oil cylinder, contiguous block moves right to extreme position, the boss of contiguous block bottom along slide bar Limited block is pressed into cavity, sliding block right-hand member loses the spacing of limited block, when retraction is continued in the shaft end of oil cylinder, due to contiguous block Extreme position is moved into, now contiguous block is moved right by slide bar band movable slider, so as to which core bar stabilization be extracted.
Preferably, the right-hand member of contiguous block is provided with T-shaped vertical slot, the both sides of the shaft end of oil cylinder, which are provided with, to be used to connect with T-shaped vertical slot The escape groove connect.This kind connection can cause the radial direction of oil cylinder axle not stress, and oil cylinder is played a protective role, improves the use of oil cylinder Life-span.
Preferably, the first self-locking inclined-plane is provided with the upper end left surface of the limited block, on the right side of the lower end of the sliding block The second self-locking inclined-plane parallel with the first self-locking inclined-plane is provided with face.After core bar is fully-inserted, limited block passes through first with sliding block Self-locking inclined-plane, the second self-locking inclined-plane, which abut, realizes self-locking, is slid so as to which anti-limited slip block is pressurized, and also can effectively compensate assembling essence Degree.
Preferably, the bottom of the sliding block is provided with wear-resisting connecting plate, one end and the solid plate spiral shell of the wear-resisting connecting plate Tether and connect, the other end of wear-resisting connecting plate and the inner bottom surface of oil cylinder fixing base connect, positioned at cavity on the wear-resisting connecting plate Surface is provided with limited block avoid holes, and the lower end side of the limited block extends to form blend stop.Wear-resisting connecting plate plays wear-resisting, branch Support, guide effect.
Preferably, the both sides of the sliding block are provided with spacing press strip, one end of the spacing press strip is connected with solid plate, limit The other end of position press strip and the upper end of oil cylinder fixing base connect, and the sliding block, the both sides of contiguous block are equipped with spacing raised line.It is spacing Press strip plays spacing, guide effect.
Therefore, core bar can be automatically inserted into before the utility model injection and positioned, core bar can be extracted after injection automatically, greatly carried High product injection molding efficiency.
