Description
Technical field
The utility model is related to mould applications more particularly to a kind of seamless ejecting structures of injection mold threaded insert.
Background technology
In some injecting products, itself need to be designed as the structure of inner threaded, and internal thread is direct using mold
Molding mode comparison is difficult, it is necessary to use very complicated mould structure to be molded extraction, the die cost that can make is significantly
Increase；If by post-processing come machining internal thread, and it can lead to problems such as that shaping efficiency is low, uniformity is poor.In addition, for interior
The screwed moulding in portion no matter which kind of molding mode used, is required for ejecting mechanism to eject moulding after die sinking, existing
Some ejecting mechanisms are usually directly to be contacted with moulding, can form trace on moulding surface in ejection process, influence to produce
Product appearance and quality.Therefore, it is necessary to it is high and without the mould structure of ejection trace to study a kind of at low cost, ratio of briquetting.
Utility model content
For overcome the prior art cause injecting products appearance has a mandril mark and complicated die structure is brought mold height into
This or post processing are molded the deficiencies of efficiency brought is low and uniformity is poor, and technical problem to be solved in the utility model is：
A kind of seamless ejecting structure of injection mold threaded insert simple in structure, easy to use is provided.
Technical solution is used by the utility model solves its technical problem：
The seamless ejecting structure of injection mold threaded insert is equipped with the thread forming inserts of helicitic texture including upper end, described
Thread forming inserts is located in the rear mold of mold, and the upper end forms the forming cavity of moulding, and the spiral shell of the upper end with mould cavity
Internal thread is formed in line structure insertion moulding, the lower end of the thread forming inserts passes through mandril and the ejector of mold rear mold
Structure is connected.
It is further that the lower end base of the thread forming inserts is equipped with Hexagon hole, and the upper end of the mandril is equipped with
With the matched turret head of hexagon ring.
It is further that the thread forming inserts lower end periphery is equipped with anti-slip tank.
It is further that the thread forming inserts lower end periphery is equipped with anti-skid rubber cushion.
It is further to further include a shaping mold insert, the upper end of the shaping mold insert is connected with mould before mold, lower end top
On the top of thread forming inserts.
It is further that the top of the thread forming inserts is equipped with shrinkage pool, and the lower end of the shaping mold insert is just inserted into
Into the shrinkage pool.
The beneficial effects of the utility model are：Moulding is completed by setting a thread forming inserts in mold
Forming internal threads integrally eject thread forming inserts and moulding followed by mandril, are finally rotated further by screwing out thread forming
Inserts can obtain finished product moulding, and entire mould structure is simple, easy to use, and product appearance is without mark, short molding cycle, one
Cause property is high, greatly reduces die cost.
Description of the drawings
Fig. 1 is the utility model structure diagram.
It is marked in figure as 1- thread forming inserts, 2- mouldings, 3- mandrils, 4- shaping mold inserts.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model includes the thread forming inserts 1 that upper end is equipped with helicitic texture, the thread forming
Inserts 1 is located in the rear mold of mold, and the upper end forms the forming cavity of moulding 2, and the helicitic texture of the upper end with mould cavity
Internal thread is formed in embedded moulding 2, the lower end of the thread forming inserts 1 passes through mandril 3 and the ejecting mechanism of mold rear mold
It is connected.The use process of the utility model is：Thread forming inserts 1 is put into mold rear mold first, and leads to its lower end
It crosses mandril 3 with mold ejection mechanism to be connected, then mold-closing injection, be molded after the shaping of moulding 2, ejecting mechanism drives mandril 3
It is moved up with thread forming inserts 1,2 ejection die of moulding finally takes moulding 2 and thread forming inserts 1 together
Under, manually or other auxiliary tools rotate thread forming inserts 1, it is made to be separated with moulding 2, is finally obtained with interior spiral shell
The moulding finished product of line.
In order to make thread forming inserts 1 and the connection of mandril 3 reliable and easy to disassemble, in the thread forming inserts 1
Lower end base is equipped with Hexagon hole, the upper end of the mandril 3 be equipped with the matched turret head of hexagon ring, both both ensure that even
The stability connect, and subsequent take out can be convenient for operate, while during last pickup, thread forming inserts 1 can be passed through
The Hexagon hole of bottom limits its rotation, so as to screwing off moulding 2.
When finally removing moulding 2 from thread forming inserts 1, in order to accelerate efficiency, manual rotation can be directly used
Mode, in order to avoid skidding, the knot of anti-slip tank or anti-skid rubber cushion can be equipped in 1 lower end of thread forming inserts periphery
Structure.
Further, a shaping mold insert 4 is further included, the upper end of the shaping mold insert 4 is connected with mould before mold, lower end top
On the top of thread forming inserts 1.Since during clamping thread forming inserts 1 in practical applications spiral shell may be caused because of gap
The position of line molding insert 1 occurs occurring situations such as eccentric in deviation and injection moulding process, by setting a shaping mold insert 4
Afterwards, it is ensured that the stability in the accuracy and injection moulding process of 1 position of thread forming inserts, so as to improve injection quality.
It, can be in the thread forming inserts 1 in order to ensure to be molded the accuracy docked with thread forming inserts 1 of mold insert 3
Top sets shrinkage pool, and the lower end of the shaping mold insert 3 is just inserted into the shrinkage pool.
The utility model completes the forming internal threads of moulding by setting a thread forming inserts in mold, with
Moulding is integrally ejected also with thread forming inserts afterwards, back-out thread forming inserts is finally rotated further by and note can be completed
The making of plastic, mould structure is simple, easy to use, and product appearance is high without mark, short molding cycle, uniformity, substantially reduces
Die cost has good practicability and application prospect.
