Abstract
The invention relates to a retreating prevention mechanism for an internal-pulling slide block. The retreating prevention mechanism comprises a driver, a tension bar, a sliding block and a guiding block, wherein the front end of the tension bar is an inclined plane, a T-shaped groove is formed in the front end of the tension bar along the inclination direction, the sliding block is in sliding fit in the T-shaped groove, the length direction of the T-shaped groove is a direction X, a direction vertical to the direction X is a direction Y, and a stroke interval is formed between the guiding block and the T-shaped groove in the direction Y; and irregular grooves are formed in the lower surface of the sliding block, and limiting structures matched with the irregular grooves in the lower surface of the sliding block are arranged on the upper surface of the inclined plane of the front end of the tension bar. The limitation is realized between the inclined plane of the tension bar and the lower surface of the sliding block by virtue of the irregular grooves, so that the driver does not retreat due to an overlarge injection molding force during the internal pulling. The stroke interval is formed between the guiding block and the T-shaped groove, so that the sliding block and the tension bar can be effectively separated, and the interference is avoided. According to the retreating prevention mechanism, the retreating of the sliding block during mold assembly is guaranteed, and the effective internal pulling action of the sliding block during the demolding is realized. The retreating prevention mechanism belongs to the technical field of mold equipment.
Description
Technical field
The invention belongs to die apparatus technical field, especially relate to a kind of can effectively anti-limited slip block retreat in take out slide block retreating prevention mechanism.
Background technology
Mould, commercial production obtains various moulds and the instrument of required product in order to methods such as injection moulding, blowing, extrusion, die casting or forging forming, smelting, punching presses.In brief, mould is used to the instrument of formed article, and this instrument is made up of various parts, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.In existing injection mold, the locking of mold insert requires high especially, if under the impulsive force when matched moulds, mold insert, because coupling mechanism force causes retrogressing not, can cause prepared product defective.So design a can effectively anti-limited slip block retreat in smoke slide block retreating prevention mechanism be at present required.
Summary of the invention
The technical problem to be solved: provide a kind of and can take out slide block retreating prevention mechanism in the retrogressing of effectively anti-limited slip block.
The technical solution used in the present invention is: take out slide block retreating prevention mechanism in one, including driver, tie rod, slide block, guide pad, described driver is positioned at tie rod rear end and is connected with tie rod, the front end of tie rod is inclined plane, tie rod is provided with T-slot in front end along incline direction, and the rear end of described T-slot is higher than front end；Guide pad lower end shape and T-slot matching form and be slidably fitted in described T-slot, the length direction of T-slot be X to, with X to vertical be Y-direction, guide pad and T-slot have stroke gap in Y-direction；The outside of guide pad is connected with slide block；The lower surface of slide block is provided with irregular groove, and the inclined plane upper surface of tie rod front end is provided with the position limiting structure that the irregular groove shape with slide block lower surface matches.
Described guide pad is through being bolted to the lower surface of slide block.
Described slide block lower surface is equipped with irregular groove in the left and right sides of guide pad.
The front end of described tie rod is provided with packing ring.
Described driver is oil cylinder.
The invention has the beneficial effects as follows: in one, take out slide block retreating prevention mechanism, realize spacing through irregular groove between inclined plane and the lower surface of slide block of pulling block, to ensure that driver will not to take out suffered injection moulding power excessive and retreat because of interior.Additionally, be provided with stroke gap between guide pad and T-slot, in order to when starting the demoulding, it is possible to effectively allow slide block separate with pulling block, it is to avoid interfere.So, the present invention both ensure that the retrogressing of slide block when avoiding matched moulds, and when also achieving the demoulding, slide block completes effective interior twitch work.

Fig. 1 is present configuration schematic diagram.
Fig. 2 is matched moulds view of the present invention.
Fig. 3 is that the present invention detaches zero boundary's view.
Fig. 4 is die opening state schematic diagram of the present invention.
In figure: 1, driver, 2, tie rod, 2.1, inclined plane, 2.2, T-slot, 3, slide block, 3.1, irregular groove, 4, guide pad, 5, packing ring.
Detailed description of the invention
Slide block retreating prevention mechanism is taken out with reference in one shown in Fig. 1-Fig. 4, including driver 1, tie rod 2, slide block 3, guide pad 4, described driver 1 is positioned at tie rod 2 rear end and is connected with tie rod 2, the front end of tie rod 2 is inclined plane 2.1, tie rod 2 is provided with T-slot 2.2 in front end along incline direction, and the rear end of described T-slot 2.2 is higher than front end；Guide pad 4 lower end shape and T-slot 2.2 matching form and be slidably fitted in described T-slot 2.2, the length direction of T-slot 2.2 be X to, with X to vertical be Y-direction, guide pad 4 and T-slot 2.2 have stroke gap in Y-direction；The outside of guide pad 4 is connected with slide block 3；The lower surface of slide block 3 is provided with irregular groove 3.1, and inclined plane 2.1 upper surface of tie rod 2 front end is provided with the position limiting structure of irregular groove 3.1 matching form with slide block 3 lower surface.
Described guide pad 4 is through being bolted to the lower surface of slide block 3.
Described slide block 3 lower surface is equipped with irregular groove 3.1 in the left and right sides of guide pad 4.
The front end of described tie rod 2 is provided with packing ring 5.
Described driver 1 is oil cylinder.
The operation principle of the present invention is: show matched moulds state in conjunction with Fig. 1 and Fig. 2, is now formed spacing between slide block 3 and tie rod 2, when slide block 3 receives certain impulse force, will not retreat.Irregular groove 3.1 between tie rod 2 and slide block 3 realizes spacing, and the impulse force that driver 1 is subject to is little, it is to avoid retreat.When die sinking, if adopting conventional dovetail configuration, so cannot detach slide block 3, so guide pad 4 of the present invention has stroke gap with T-slot 2.2 in Y-direction, so when tie rod 2 is under driver 1 pulls, the relative motion of a Y-direction is had between tie rod 2 and guide pad 4, the irregular groove 3.1 of slide block 3 lower surface can separate with the inclined plane 2.1 of tie rod 2 simultaneously, it is no longer influenced by spacing interference, after the lower surface of slide block 3 and the inclined plane of tie rod 2 are kept completely separate, now guide pad 4 also reaches 1 boundary's point in T-slot 2.2, tie rod 2 drives guide pad 4 to move, guide pad 4 band movable slider 3 moves, complete interior twitch to make.
