be equipped with locking mechanism between centre form and the external mold, locking mechanism includes supporting seat one and locking lever one, supporting seat one is established on the external mold, supporting seat one has lockhole one, locking lever one is articulated to be established on the centre form, locking lever one is established in lockhole one with the adaptation, can dismantle on the locking lever and be equipped with the nut.

Be equipped with locking Assembly between the opposite side of two centre forms, locking Assembly includes supporting seat two and locking lever two, supporting seat two is established on an centre form, supporting seat two has lockhole two, locking lever two is articulated to be established on another centre form, locking lever two is established in lockhole two with the adaptation, can dismantle on the locking lever two and be equipped with the nut.

The inner die is annular and comprises a pair of lower inner half die plates, a pair of upper inner half die plates and a pair of inner die plates which are oppositely arranged,

triangular supports are respectively arranged on the opposite surfaces of the pair of inner formworks, a split lead screw and a split hand wheel are arranged between the pair of triangular supports,

an opening and closing screw rod and an opening and closing hand wheel are respectively arranged between the lower inner half template and the upper inner half template and the triangular supports,

an inner template is contacted with the lower inner half template through the outer side edge, the lower inner half template is contacted with the upper inner half template through the surface, and the upper inner half template is contacted with the other inner template through the outer side edge.

The outer die is hinged on the bottom die.

In the work of the invention, the outer die comprises a first outer die, a second outer die, a third outer die and a fourth outer die which are annularly arranged, the two inner dies are connected in the annular cavity, and a product die cavity is formed among the outer die, the inner dies and the two inner dies, so that the casting molding is convenient. A locking mechanism is arranged between the inner die and the outer die and is connected with the supporting seat through a first locking rod in a matching mode, so that the positions of the inner die and the outer die are fixed conveniently, and the forming reliability is improved.

Detailed Description

The invention is shown in figure 1-2, comprising a bottom die 1, an outer die and two inner dies 2, 3, wherein the outer die comprises an outer die I21, an outer die II 22, an outer die III 23 and an outer die IV 24, the outer die I, the outer die II, the outer die III and the outer die IV are annularly arranged on the bottom die and form an annular cavity, the two inner dies are arranged in the annular cavity at intervals,

be equipped with locking mechanism between centre form and the external mold, locking mechanism includes supporting seat 41 and locking lever 42, supporting seat one is established on the external mold, supporting seat one has lockhole one, locking lever one articulates and establishes on the centre form, locking lever one is established in lockhole one with the adaptation, locking lever one is last to dismantle and is equipped with the nut. The nut is in threaded connection with the first lock rod and is located on two sides of the first support seat and used for locking.

Be equipped with locking Assembly between the opposite side of two centre forms, locking Assembly includes two 51 and two 52 locking levers of supporting seat, two are established on an centre form in the supporting seat, two have lockhole two, two articulated establishing on another centre form in the locking lever, two adaptations of locking lever are established in lockhole two, can dismantle on the locking lever two and be equipped with the nut. The nut is in threaded connection with the second locking rod, and the nut is located on two sides of the second supporting seat and used for locking.

Through setting up locking Assembly for the position relatively fixed between two centre forms, the shaping of being convenient for, the operation is reliable.

The inner mold 3 is annular and comprises a pair of lower inner half mold plates 31, a pair of upper inner half mold plates 32 and a pair of inner mold plates 33 which are oppositely arranged,

an opening and closing screw rod 8 and an opening and closing hand wheel 6 are respectively arranged between the lower inner half template and the upper inner half template and the triangular supports,

an opening and closing screw rod 8 and an opening and closing hand wheel 6 are arranged between the pair of lower inner half templates and the triangular supports between the pair of lower inner half templates and the pair of upper inner half templates and the triangular supports between the pair of upper inner half templates;

The internal model acts as: firstly, respectively rotating a plurality of opening and closing hand wheels, and simultaneously retracting two side edges a and b of a lower inner half template and an upper inner half template inwards through an opening and closing screw rod (namely a positive and negative tooth screw rod);

after the upper half template and the lower half template are completely staggered, the opposite pull hand wheel is rotated, and the upper half template and the lower half template move towards the center through the opposite pull screw rod (namely a positive and negative screw rod).

The internal mold is split, so that the demolding and the operation are convenient.
