Abstract
The utility model relates to technical field of mold, especially a kind of a plurality of thread, which utilizes, inside contracts sliding block demolding structure, compared with prior art, which includes intermediate fuse, inner slide fuse A, inner slide fuse B, inner slide pressing plate and inner slide positioning ring using sliding block demolding structure is inside contracted；Thread recessing groove is equipped on the inner slide positioning ring top；The intermediate fuse with three pieces inner slide fuse A and three pieces inner slide fuse B is attached in a manner of dovetail；Inner slide pressing plate carries out limitation axial restraint to three pieces inner slide fuse A and three pieces inner slide fuse B；It is attached on the outside of inner slide fuse A and inner slide fuse B by thread and inner slide positioning ring upper end, it uses double action structure design without spin, thread is using radial demoulding, thread tail end will not deformed in tension, have many advantages, such as production stablize, small the reductions injection molding machine of module shape position, sliding block movement fastly, injection cycle it is short.
Description
Technical field
The present invention relates to technical field of mold, especially a kind of a plurality of thread, which utilizes, inside contracts sliding block demolding structure.
Background technique
In the design of the mold with general thread, the thread mode fuse of this thread mold in the prior art is
It is demoulded using rotation mode, but some threads are equipped with thread recessing groove, the mode fuse equipped with thread recessing groove is then
It can not be demoulded using traditional rotation mode.
Summary of the invention
For solve the problems, such as defect present in thread mold in the prior art and, provide a kind of a plurality of thread using inside contracting cunning
Block demolding structure.
The present invention is that technical solution used by solving its technical problem is: a plurality of thread of the invention utilizes and inside contracts sliding block
Demolding structure includes intermediate fuse, inner slide fuse A, inner slide fuse B, inner slide pressing plate and inner slide positioning ring；Institute
The inner slide positioning ring top stated is equipped with thread recessing groove；It is sliding in the intermediate fuse and three pieces inner slide fuse A and three pieces
Block fuse B is attached in a manner of dovetail；Inner slide pressing plate carries out three pieces inner slide fuse A and three pieces inner slide fuse B
Limit axial restraint；It is attached on the outside of inner slide fuse A and inner slide fuse B by thread and inner slide positioning ring upper end.
The beneficial effects of the present invention are: compared with prior art, a plurality of thread of the invention is tied using sliding block demoulding is inside contracted
Structure is designed using double action structure without spin, thread using radial demoulding, thread tail end will not deformed in tension, there is production to stablize,
The advantages that small reduction injection molding machine of module shape position, sliding block movement are fastly, injection cycle is short.
Detailed description of the invention
With reference to the accompanying drawings and detailed description to a plurality of thread of the invention using inside contract sliding block demolding structure make into
One step explanation.
Fig. 1 is that a plurality of thread of the invention utilizes the schematic cross-sectional view for inside contracting sliding block demolding structure；
Fig. 2 is that a plurality of thread of the invention utilizes the overlooking structure diagram for inside contracting sliding block demolding structure.
Specific embodiment:
As depicted in figs. 1 and 2, a plurality of thread of the invention includes intermediate fuse 1, interior cunning using sliding block demolding structure is inside contracted
Block fuse A2, inner slide fuse B3, inner slide pressing plate 4 and inner slide positioning ring 5.Intermediate fuse 1 and three pieces inner slide fuse
A2 and three pieces inner slide fuse B2 is attached in a manner of dovetail.Inner slide pressing plate 4 is to three pieces inner slide fuse A2 and three pieces
Inner slide fuse B3 carries out limitation axial restraint.It is equipped with thread 6 on the outside of inner slide fuse A2 and inner slide fuse B3, in inner slide
It also is provided with thread 6, inner slide fuse A2 and inner slide fuse B3 on the inside of 5 upper end of positioning ring and passes through thread 6 and inner slide positioning ring 5
Upper end is attached, and is equipped with thread recessing groove 7 in 6 upper end of thread of inner slide positioning ring 5.
As depicted in figs. 1 and 2, when mold is opened, intermediate fuse 1 carries out steering twitch in advance, due to intermediate fuse 1 with
Three pieces inner slide fuse A2 and three pieces inner slide fuse B3 is attached in a manner of dovetail, therefore, when intermediate fuse 1 is toward axis
To when the actuation of direction, inner slide fuse A2 and inner slide fuse B3 actuation simultaneously are driven.Due to inner slide fuse A2 and inner slide
Fuse B3 is limited axial restraint by inner slide pressing plate 4, can not actuation, can only be reduced toward radially direction is mobile, to make to produce
Product can be demoulded smoothly.Since it uses double action structure design without spin, thread will not tension change using radial demoulding, thread tail end
Shape has many advantages, such as that production is stablized, the small reduction injection molding machine of module shape position, sliding block movement is fast, injection cycle is short.
In conclusion compared with prior art, a plurality of thread of the invention, which utilizes, inside contracts sliding block demolding structure with as follows
Advantage: being designed using double action structure without spin, thread using radial demoulding, thread tail end will not deformed in tension, have production steady
The advantages that fixed, the small reduction injection molding machine of module shape position, sliding block movement are fastly, injection cycle is short.
Embodiment according to the present invention the present invention is described the description of property and not restrictive, it should be appreciated that this
The protection scope of invention is not limited thereto, without departing from the relevant scope of protection defined by the claims, this
The technical staff in field can make change and/or modification, and should be covered by the protection scope of the present invention.
