Description

A kind of mold liftout attachment

Technical field

The utility model relates to a kind of device that makes mould and separation of products, relates in particular to a kind of mold liftout attachment.

Background technology

At the initial stage of designing mould, analytic product special formed is again Transparent Parts, and surface requirements is very high, and there are the features of much drawing inside, and the thimble of arranging is also forbidden in inside, so can not be with common thimble or lifter ejection.

Summary of the invention

The purpose of this utility model is to solve because interiors of products draws, with product from the mould ejection hard problem, provide a kind of simple in structure, eject easily mold liftout attachment.

In order to achieve the above object, the utility model provides a kind of mold liftout attachment, it is characterized in that, comprise mavable module core, be provided with mold insert in the mavable module core, mold insert is provided with sliding block inclined guide pillar and straight guide pillar, and an end of sliding block inclined guide pillar is connected with second layer ejector retainner plate, one end of straight guide pillar is connected with the ground floor ejector retainner plate, and the splay end of described sliding block inclined guide pillar is provided with slide block.

Preferably, splay end and the slide block of described sliding block inclined guide pillar are complementary, and slide block is located between the splay end and mavable module core of sliding block inclined guide pillar.

Preferably, the quantity of the quantity of described sliding block inclined guide pillar and straight guide pillar is at least 4.

Preferably, described second layer ejector retainner plate is connected die opening mechanism with the ground floor ejector retainner plate and connects.

The utility model is simple in structure, and mold insert and product are ejected the mavable module core end face simultaneously, and inner slide block ejects product come again, by Double-ejection, so that mould ejection is more convenient, simultaneously, the feature of can well treatment product drawing.

Description of reference numerals

1 is mavable module core, and 2 is mold insert, and 3 is slide block, and 4 is the sliding block inclined guide pillar, and 5 is second layer ejector retainner plate, and 6 is the ground floor ejector retainner plate, and 7 is die opening mechanism, and 8 is straight guide pillar, and 9 is product.

The specific embodiment

For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.

Embodiment

The utility model is a kind of mold liftout attachment, as shown in Figure 1, is a kind of structural representation of mold liftout attachment.Product 9 is placed on the centre position on the mavable module core 1, and mavable module core 1 is placed on the top position of second layer ejector retainner plate 5 and ground floor ejector retainner plate 6.

As shown in Figure 2, be the A-A cutaway view of Fig. 1.Product 9 is enclosed within on the mold insert 2, mold insert 2 is installed in the mavable module core 1, sliding block inclined guide pillar 4 and straight guide pillar 8 are installed on the mold insert 2, the other end of sliding block inclined guide pillar 4 is connected with second layer ejector retainner plate 5, the other end of straight guide pillar 8 is connected with ground floor ejector retainner plate 6, between the splay end of sliding block inclined guide pillar 4 and the mavable module core 1 slide block 3 is installed, and the splay end of sliding block inclined guide pillar 4 and slide block 3 be complementary, slide block 3 withstands on pulling on of product 9 both sides.

As shown in Figure 3, remove schematic diagram behind second layer ejector retainner plate 5 and the ground floor ejector retainner plate 6 for a kind of mold liftout attachment.The quantity of the quantity of sliding block inclined guide pillar 4 and straight guide pillar 8 is at least 4.In the present embodiment, the quantity of the quantity of sliding block inclined guide pillar 4 and straight guide pillar 8 is 4.

On the face that is connected with mavable module core 1 on the product 9 a lot of drawing arranged, can not there be the thimble seal inside that adds product 9, so adopt dynamic model mold insert 2 and product 9 to eject together, after mold insert 2 and product 9 eject together, because drawing of product 9 itself are wrapped in mold insert 2, cause product 9 with mold insert 2 can not automatic trip from.At four slide blocks 3 of mold insert 2 inner increases the both sides of product 9 are strutted (as shown in Figure 4), have at last manipulator with sucker product 9 to be taken off.

Ejection process is as follows:

1: ground floor ejector retainner plate 6 ejects 50mm, and the straight guide pillar 8 on the mold insert 2 and ground floor ejector retainner plate 6 are fixing, and product 9 is wrapped in the end face that mold insert 2 is ejected mavable module core 1 together.

2: when ground floor ejector retainner plate 6 moves to 50mm, utilize die opening mechanism 7 that two-layer ejector retainner plate (ground floor ejector retainner plate 6 and second layer ejector retainner plate 5) is towed out (as shown in Figure 5).

3: second layer ejector retainner plate 5 continues to eject 16mm, and an end of sliding block inclined guide pillar 4 and second layer ejector retainner plate 5 is fixing, and the slope driving slide block 3 by sliding block inclined guide pillar 4 ejects and wraps in the outer product 9 of mold insert 2.

4: with the sucker on the manipulator product 9 is taken off at last.

Attention:

Ground floor ejector retainner plate 6 ejects Data Control between 45～55mm, can not too high (preventing that mold insert 2 from detaching mavable module core 1), and can not too low (avoiding slide block 3 not eject mavable module core 1 surface).
