Abstract
The utility model relates to a demoulding mechanism for a threaded mould. The conventional demoulding mechanism for the threaded mould is easy to cause the defect of a wedge slit on a product while demoulding. For this reason, the demoulding mechanism for the threaded mould comprises a mould, wherein the mould is composed of a thread core and an outer mould; the front part of the thread core is provided with an external thread, as well as equipped with a rotation mechanism and a retreat mechanism; and the retreat mechanism is linked with the rotation mechanism. A gear shaft is produced at the rear part of the thread core; the gear shaft and a rack form the rotation mechanism; the retreat mechanism comprises a lead screw and a nut, and the lead screw and the nut form a lead screw/nut transmission mechanism; the nut is fixed on a mould push plate; a gear is arranged on the lead screw, and the gear is engaged with the gear shaft; and the screw pitch of the lead screw is equal to the screw pitch of the external thread on the thread core. The demoulding mechanism for the threaded mould, disclosed by the utility model, has the advantages of being simple in structure, reliable in demoulding, free from a wedge slit in a finished product, and suitable for a production demoulding process for various injection products containing internal threads.
Description
Technical field
The utility model relates to a kind of thread mold releasability mechanism.
Background technology
Injection moulding adds man-hour, and thread core tool comprises tooth core and external mold, and knockout course dens in dente core will rotate to be retreated, and this just requires to need to be equipped with rotating mechanism and to retreat mechanism, and the two must synchronization action.Existing rotating mechanism and the complex structure of retreating mechanism, it is not in place that long-term friction loss adds that the gap of transmission mechanism often causes the tooth core to return, and produces behind the product stripping and split seam.
The utility model content
The technical problem that the utility model will solve is how to overcome existing thread mold releasability mechanism to cause product to produce the defective of splitting seam easily, and a kind of thread mold releasability mechanism is provided.
For solving the problems of the technologies described above, this thread mold releasability mechanism comprises mould, and this mould is made up of tooth core and external mold; Its dens in dente core front portion is provided with external screw teeth, and is furnished with rotating mechanism, and the tooth core is arranged in the mould push pedal; This mould push pedal is furnished with the mechanism of retreating, and this retreats mechanism and the interlock of said rotating mechanism, drives the tooth core through the mould push pedal and retreats; Realize the demoulding, it is characterized in that: said tooth core rear portion is shaped on gear shaft, and this gear shaft and a tooth bar are formed rotating mechanism; The said mechanism of retreating comprises leading screw and screw, and the two forms leading screw/screw transmission mechanism, and screw is fixed in the mould push pedal; Leading screw is provided with gear, the engagement of this gear and said gear shaft, and the pitch of external screw teeth is identical on leading screw pitch and the said tooth core.
So design, rotating mechanism is with to retreat mechanism structure simple, and synchronous interaction is reliable.Drive the tooth core at rotating mechanism and rotate a circle, retreat mechanism and drive the distance that the tooth core is retreated, equal the pitch of a said external screw teeth just.
As optimization, comprise many group moulds, above-mentioned each mould all is arranged in the same mould push pedal, and is furnished with a rotating mechanism respectively, retreats the mechanism urges demoulding by same.So design can the injection mouldings simultaneously of a plurality of products, the demoulding simultaneously.
That the utility model thread mold releasability mechanism has is simple in structure, the demoulding reliable, finished product does not have the advantage of splitting seam, is suitable in the production knockout course of the various injecting products that contain internal thread.
Description of drawings
Below in conjunction with accompanying drawing this thread mold releasability mechanism is described further:
Fig. 1 is the structural representation of this thread mold releasability mechanism.
Among the figure: 1 is that tooth core, 2 is that external mold, 3 is that mould push pedal, 4 is that gear shaft, 5 is that tooth bar, 6 is that leading screw, 7 is that screw, 8 is that gear, 9 is an injecting products.
The specific embodiment
Embodiment one: as shown in Figure 1, this thread mold releasability mechanism comprises mould, and this mould is made up of tooth core 1 and external mold 2; Its dens in dente core 1 front portion is provided with external screw teeth, and is furnished with rotating mechanism, and tooth core 1 is arranged in the mould push pedal 3; This mould push pedal 3 is furnished with the mechanism of retreating, and this retreats mechanism and the interlock of said rotating mechanism, drives tooth core 1 through mould push pedal 3 and retreats; Realize the demoulding, it is characterized in that: said tooth core 1 rear portion is shaped on gear shaft 4, and this gear shaft 4 and a tooth bar 5 are formed rotating mechanism; The said mechanism of retreating comprises leading screw 6 and screw 7, and the two forms leading screw/screw transmission mechanism, and screw 7 is fixed in the mould push pedal 3; Leading screw 6 is provided with gear 8, and the pitch of external screw teeth is identical on this gear 8 and said gear shaft 4 engagements, leading screw 6 pitch and said tooth core 1.
As shown in Figure 1, this thread mold releasability mechanism comprises many group moulds, and above-mentioned each mould all is arranged in the same mould push pedal, and is furnished with a rotating mechanism respectively, retreats the mechanism urges demoulding by same.
Claims (2)
1. a thread mold releasability mechanism comprises mould, and this mould is made up of tooth core and external mold; Its dens in dente core front portion is provided with external screw teeth, and is furnished with rotating mechanism, and the tooth core is arranged in the mould push pedal; This mould push pedal is furnished with the mechanism of retreating, and this retreats mechanism and the interlock of said rotating mechanism, drives the tooth core through the mould push pedal and retreats; Realize the demoulding, it is characterized in that: said tooth core rear portion is shaped on gear shaft, and this gear shaft and a tooth bar are formed rotating mechanism; The said mechanism of retreating comprises leading screw and screw, and the two forms leading screw/screw transmission mechanism, and screw is fixed in the mould push pedal; Leading screw is provided with gear, the engagement of this gear and said gear shaft, and leading screw pitch is identical with external screw teeth pitch on the said tooth core.
2. thread mold releasability as claimed in claim 1 mechanism is characterized in that: comprise many group moulds, above-mentioned each mould all is arranged in the same mould push pedal, and is furnished with a rotating mechanism respectively, retreats the mechanism urges demoulding by same.
