Description

A kind ofly prevent the excessive false slide block structure causing deformation of products of cover half package power

Technical field

The utility model belongs to dark chamber die casting technical field, particularly relates to a kind ofly preventing the excessive false slide block structure causing deformation of products of cover half package power.

Background technology

In the mould application of deep cavity shape foundry goods, the package power of cover half is all larger, and this just causes the product when die sinking easily to embrace cover half, and is taken away by cover half, and in die sinking process, product is easily pulled, drawing crack brings very large hidden danger to product quality.In prior art, the general spring ejection mechanism that adopts solves cover half package power problem (as shown in Figure 1), but the result of use of spring and service life are the weakness of this structure always, in actual press casting procedure, stability is good not, and spring easily occurs that failure phenomenon causes die sinking to be broken down.

Summary of the invention

Technical problem to be solved in the utility model is to provide and a kind ofly prevents the excessive false slide block structure causing deformation of products of cover half package power, false slide block is adopted to push down product, during die sinking, vacation slide block controls outwards to slide by Angle Pin, leave time delay gap between slotted hole during cover half die sinking on Angle Pin and take-up housing, after product certain distance is thrown off in cover half die sinking, Angle Pin just contacts with take-up housing and makes it to slide.

The utility model solves the technical scheme that its technical problem adopts: provide a kind of and prevent the excessive false slide block structure causing deformation of products of cover half package power, comprise cover half, dynamic model and slippage side form, described fixed half and moving half while be equipped with slippage side form, another side is equipped with false slide block, described false slide block is by the anti-deformation block of top, T-shaped slide-and-lock block and the take-up housing be positioned at outside anti-deformation block and T-shaped slide-and-lock block of below form, described T-shaped slide-and-lock block and anti-deformation block are arranged between fixed half and moving half, with laterally projecting on described anti-deformation block, described laterally projecting upper end of blocking foundry goods opening part, the Angle Pin that described cover half tilts with it with one, described Angle Pin one end and cover half are in being fixedly connected with, the other end stretches out, the slotted hole that described take-up housing matches with Angle Pin with one, under the tight split state of assembling die, between described slotted hole and Angle Pin, the one side of the combined mould in face fits tightly, there is gap in another side.

T-shaped slide-and-lock block is housed below described anti-deformation block contact with dynamic model, described T-shaped slide-and-lock block slides along dynamic model contact surface.

Beneficial effect

The utility model has the advantage of, false slide block is adopted to push down product, during die sinking, vacation slide block controls outwards to slide by Angle Pin, after product certain distance is thrown off in cover half die sinking, Angle Pin just contacts with take-up housing and makes it to slide, in use very stable, avoid product and occur that batch is pulled, the scrapping of drawing crack.

Detailed description of the invention

Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.

As shown in Figures 2 and 3, a kind ofly prevent the excessive false slide block structure causing deformation of products of cover half package power, comprise cover half 1, dynamic model 2 and slippage side form 3, described cover half 1 and dynamic model 2 while be equipped with slippage side form 3, another side is equipped with false slide block 4, described false slide block 4 is by the anti-deformation block 42 of top, the T-shaped slide-and-lock block 41 of below and the take-up housing 43 be positioned at outside anti-deformation block 42 and T-shaped slide-and-lock block 41 form, described T-shaped slide-and-lock block 41 and anti-deformation block 42 are arranged between cover half 1 and dynamic model 2, with laterally projecting 45 on described anti-deformation block 42, described laterally projecting 45 upper ends of blocking foundry goods opening part, with an Angle Pin tilted with it 5 on described cover half 1, described Angle Pin 5 one end with cover half 1 in being fixedly connected with, the other end stretches out, the slotted hole 44 that described take-up housing 43 matches with Angle Pin 5 with one, under the tight split state of assembling die, between described slotted hole 44 and Angle Pin 5, the one side of the combined mould in face fits tightly, there is gap in another side.

Described anti-deformation block 42 is equipped with T-shaped slide-and-lock block 41 below and contacts with dynamic model 2, and described T-shaped slide-and-lock block 41 slides along dynamic model 2 contact surface.

In actual applications, after die casting completes, dynamic model 2 moves down, slippage side form 3 transverse movement starts the demoulding, now false slide block 4 is followed dynamic model 2 due to gravity and is moved downward together, the fitting tightly of one side of the slotted hole 44 on take-up housing 43 and Angle Pin 5 combined moulds starts to be separated, and the gap between another side and Angle Pin 5 reduces gradually, laterally projecting 45 push down foundry goods opening portion simultaneously, foundry goods is forced to move down the demoulding along with dynamic model 2, the another side moving down slotted hole 44 along with take-up housing 43 gradually contacts with Angle Pin 5, and make false slide block 4 move along Angle Pin 5 under gravity, on false slide block 4, T-shaped slide-and-lock block 41 slides along dynamic model 2, laterally projecting 45 progressively outwards move the contact departed from foundry goods, after dynamic model 2 is thrown off completely, false slide block 4 skids off simultaneously, foundry goods then with dynamic model 2, cover half 1 is thrown off, complete the demoulding.
