Abstract

The utility model discloses a slide delayed core-pulling die which comprises a male die and a female die, wherein the male die is provided with a front die core, the female die is provided with a rear die core, the rear die core consists of a first module and a second module, the female die is provided with two slide blocks sliding longitudinally, the first module and the second module are respectively fixed on the two slide blocks, the two slide blocks are internally provided with symmetrical slant guide pillar holes, two oblique cylinders matched with the guide pillar holes are arranged on the male die correspondingly, and the inner diameter of the cross section of the guide pillar hole is larger than that of the cross section of the oblique cylinder. According to the slide delayed core-pulling die, the inner diameter of the cross section of the guide pillar hole is increased by certain size due to the match of the guide pillar hole of the slide block and the oblique cylinder, so that after the male die and the female die are separated by a certain distance in die sinking, the two slide blocks are separated by the oblique cylinder, so that the sequential demoulding of the die is realized, products are prevented from being stuck on the die, and the production capacity is improved.

Description

The row position postpones to loose core mould

Technical field

The utility model relates to mould manufacturing field, and particularly a kind of position of going postpones to loose core mould.

Background technology

Along with development in science and technology, the progress of society, the growth at full speed of domestic various places industry in recent years, a lot of enterprises feel more pressure in order to reduce cost; The competition of die industry at present too fierceness has only the quality of raising, raises the efficiency, develops skill and improve stability and could satisfy Enterprise's Sustainable Development; In mould designed, because the structure diversity of product, therefore the mould of design needed multidirectional loosing core, and when still simultaneously plural direction being loosed core, can cause the product sticking to mould, and the demoulding smoothly influences product quality and production efficiency.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of use mould to throw off in order, and the row position that has solved the sticking to mould problem postpones to loose core mould.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of row position postpones to loose core mould, comprise male model and master mold, described male model is provided with preceding core rod, described master mold is provided with the back core rod, described back core rod is made up of first module and second module, described master mold is provided with the slide block of two longitudinal sliding motions, first module and second module are separately fixed on two slide blocks, be provided with the oblique guide pillar hole of symmetry in described two slide blocks, corresponding male model is provided with two batter posts with guide pillar hole coupling, and the cross section internal diameter in described guide pillar hole is greater than the internal diameter in batter post cross section.

As further improvement of the utility model, described master mold is provided with for the ccontaining slotted eye in batter post top.

As further improvement of the utility model, the upper and lower of core rod before described two batter posts are separately fixed at, and two batter posts are increased to the angle on the master mold direction gradually by male model.

The beneficial effects of the utility model are: the utility model utilizes cooperating of slide block guide post hole and batter post, the cross section internal diameter in guide pillar hole is increased certain size, like this when die sinking Angle Pin male model with two slide blocks are separated after master mold separates certain position, realized the mould demoulding in order, avoided product to produce the problem of sticking to mould, improved the production production capacity, this mould structure simplicity of design, processing cost is lower, stability is high, easy to operate, the debugging simple and easy, reduce human and material resources, financial resources, thereby realized energy-saving and cost-reducing.

The mark of each parts is as follows in the accompanying drawing: 1, male model; 2, master mold; 3, preceding core rod; 4, first module; 5, second module; 6, slide block; 7, guide pillar hole; 8, batter post; 9, slotted eye.

The specific embodiment

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection domain.

Fig. 1-3 has shown a kind of position postpone to loose core a kind of embodiment of mould of going of the utility model, comprise male model 1 and master mold 2, described male model 1 is provided with preceding core rod 3, described master mold 2 is provided with the back core rod, described back core rod is made up of first module 4 and second module 5, described master mold 2 is provided with the slide block 6 of two longitudinal sliding motions, first module 4 and second module 5 are separately fixed on two slide blocks 6, be provided with the oblique guide pillar hole 7 of symmetry in described two slide blocks 6, corresponding male model 1 is provided with two batter posts 8 with guide pillar hole 7 couplings, the cross section internal diameter in described guide pillar hole 7 is greater than the internal diameter in batter post 8 cross sections, described master mold 2 is provided with for the ccontaining slotted eye 9 in batter post 8 tops, the upper and lower of core rod 3 before described two batter posts 8 are separately fixed at, and two batter posts 8 are increased to the angle on master mold 2 directions gradually by male model 1, when male model 1 and master mold 2 closures, as shown in Figure 1, two slide blocks 6 also drive first module 4 and second module, 5 closures simultaneously under the effect of two batter posts 8, and the back core rod after the closure again with preceding core rod 3 closures; When male model 1 and master mold 2 began separately, back core rod at first separated with preceding core rod 3, finished to loose core the first time, at this time since the cross section internal diameter in guide pillar hole greater than batter post, so when core rod separated certain distance with preceding core rod 3, first module 4 and second module 5 still were in closure state, as shown in Figure 2; When male model 1 and master mold 2 continued separately, two slide blocks 6 began under the effect of batter post 8 separately, thereby drove first module 4 and second module 5 separately, finished secondary and loosed core, and product can be because of the not demoulding and cause product to glue master mold in order like this; Make mould more stable in forming process, the efficient height.
