A kind of projection shaping mechanism
Technical field
The utility model is related to mould manufacture field, and in particular to a kind of projection shaping mechanism.
Background technology
Injection mold is a kind of instrument for producing plasthetics, is also to confer to plasthetics complete structure and accurate dimension
Instrument.Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches, refers specifically to melt heated
Plastics by injection machine high pressure inject die cavity, after cooling and solidifying, obtain formed products.
Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, cover half
On the fixed form of injection (mo(u)lding) machine.In injection moulding, dynamic model constitutes running gate system and die cavity with cover half closure, opens
Dynamic model and cover half separate to take out plastic products during mould.In order to reduce heavy mold design and manufacturing effort, injection mould
Employ standard die set mostly.
In injecting products, often there are many bulge-structures, when solving the shaping of this class bulge-structure, in injection mold
There are oblique top pin, Angle Pin angled-lift splits to coordinate two kinds using more.Oblique top pin is because that through lower template, can only be used in vertical plane
The shaping of side projection;And Angle Pin angled-lift splits is then pressed in lower template because Angle Pin is fixed on cope plate, angled-lift splits, by Angle Pin
Angled-lift splits is promoted with respect to lower template one-way movement, the often shaping applied to outer side projections, cavity.
Due to traditional Angle Pin angled-lift splits can only one-way movement, it is convex needing to be molded insides of pipes as shown in figure 11
When block, inside cavities projection, the demoulding can destroy projection, it is impossible to meet use requirement.
Utility model content
In order to solve the above problems, the utility model provides a kind of projection shaping mechanism.
The utility model solves the technical scheme that its technical problem used:A kind of projection shaping mechanism, including it is tiltedly sliding
The Angle Pin of block and driving angled-lift splits, angled-lift splits includes:
Shaping group, shaping group surface is provided with some sliding blocks, and the direction that sliding block can be moved perpendicular to angled-lift splits is slided, and in table
Face is provided with groove;
Slide Group, Slide Group is provided with connecting portion, and connecting portion is used to connect Slide Group and shaping group, to realize that Slide Group is remote
During shaping group, first draw sliding block in and drive shaping group again.
Further, connecting portion includes:
First connecting portion, first connecting portion one end connection sliding block, other end connection Slide Group, for Slide Group away from shaping
During group, sliding block is drawn in;
Second connecting portion, second connecting portion one end connection shaping group, the other end connection Slide Group, for Slide Group away from into
Shaping group is driven after the segment distance of type group one.
Further, first connecting portion is provided with T-shaped card article, and T-shaped card article is higher than the other end close to one end of Slide Group;Sliding block
Provided with the neck matched with T-shaped card article;T-shaped card article coordinates to draw sliding block in when realizing Slide Group away from shaping group with neck.
Further, second connecting portion one end is fixedly connected with shaping group, and the other end is through Slide Group and sets a block, second
The length of connecting portion is more than the thickness of Slide Group.
Further, if second connecting portion includes the uniform bolt stem for being located at shaping group outer rim, bolt length, which is more than, to be slided
The thickness of group, its screw thread one end connects shaping group through Slide Group, and the other end passes through nut clamping Slide Group.
Further, second connecting portion one end is fixedly connected with Slide Group, and the other end is through shaping group and sets a block, second
The length of connecting portion is more than the thickness of shaping group.
The beneficial effects of the utility model are:In the demoulding, while Angle Pin promotes the Slide Group demoulding, Slide Group is drawn in
Sliding block in shaping group, after sliding block gathering, Slide Group drives shaping group to be stripped again, will not destroy projection, keep projection
Completely, it is adaptable to the processing and forming of projection in various cavitys.

Embodiment
Reference picture 1, the utility model is a kind of projection shaping mechanism, includes the Angle Pin of angled-lift splits 2 and driving angled-lift splits 2
1, angled-lift splits 2 is made up of shaping group 22 and Slide Group 21.Wherein, the surface of shaping group 22 is provided with some sliding blocks 221, and sliding block 221 can
The direction moved perpendicular to angled-lift splits 2 is slided, and is provided with groove 223 in surface;Slide Group 21 connects Angle Pin 1, and provided with company
Socket part, the connecting portion is used to connect Slide Group 21 and shaping group 22, during realizing Slide Group 21 away from shaping group 22, first draws in
Sliding block 221 drives shaping group 22 again.
Reference picture 2 is to Fig. 8, and the surface of shaping group 22, which is circumferentially with four connecting portions of sliding block 221, includes the He of first connecting portion 211
Second connecting portion 213.The circumferentially disposed four T-shaped card articles 212 in the one end of first connecting portion 211, and T-shaped card article 212 is close to Slide Group
