The specific embodiment
The invention will be further described with embodiment below, is not practical range of the present invention is limited to this.
A kind of rotation laminated type injection mold, comprise that cover half is overall and dynamic model is overall, described cover half totally comprises solid plate and cover half chamber, described dynamic model totally comprises moving platen, ejecting mechanism and dynamic model chamber, described dynamic model chamber is connected with a rotating disc 1, the axle rotation of this rotating disc 1 moving die cavity, mould one side are provided with and drive the drive unit that rotating disc 1 rotates, and described rotating disc 1 is equipped with at least two mold inserts 2 that are provided with according to product thickness.Opaque products according to specific thicknesses is divided into a plurality of five equilibriums, each five equilibrium is provided with a mold insert 2, certainly according to the different-thickness and the size of opaque products, divide the five equilibrium and the number that mold insert 2 is set of opaque products flexibly, and described cover half chamber is provided with the die cavity 3 that cooperates with mold insert 2, and the number of this die cavity 3 also is that the number of corresponding mold insert 2 rationally is provided with.Mold insert 2 is cooperated with die cavity 3, and lamination one by one in order is with the opaque products injection mo(u)lding of specific thicknesses.
Wherein, described drive unit comprises fixed head 4, and these fixed head 4 one ends are provided with drive rod 5, described fixed head 4 offers groove 6, be provided with tooth bar 7 in this groove 6, tooth bar 7 one ends are connected with drive rod 5, and described rotating disc 1 periphery is equipped with the gear 8 that cooperates with tooth bar 7.After tooth bar 7 meshed with gear 8, described drive rod 5 promoted tooth bars 7 and moves in groove 6, and 1 rotation of driven rotary dish realized repeatedly injection moulding of the present invention with this when tooth bar 7 moved.
Wherein, described rotating disc 1 is provided with at least two group mold inserts 2, every group of mold insert 2 is at least two, described cover half chamber is provided with at least two group die cavities 3 corresponding with the mold insert 2 of rotating disc 1, what every group of die cavity 3 and mold insert 2 were corresponding is provided with at least two, described at least two group mold inserts 2 are grouped on the rotating disc 1 uniformly, every group of mold insert 2 is provided with at least two mold inserts 2 and distributes one by one from small to large, die cavity 3 with the cover half chamber is equipped with simultaneously, in use, be provided with like this and be beneficial to the injection moulding of carrying out a plurality of products simultaneously, the size of its a plurality of products, volume and shape etc. can be the same also can be different, so the setting of this kind form has more practicality.
A kind of injection moulding process that rotates the laminated type injection mold:
A, matched moulds for the first time make mold insert 2 and die cavity 3 matched moulds.This time matched moulds selects minimum mold insert 2 to cooperate with die cavity 3.
B, injecting glue for the first time: to injecting glues in the mold insert 2 of the minimum behind the matched moulds and the die cavity 3.
C, cooling for the first time: making the plastic cement cooling forming that is filled into minimum die cavity 3 is the first of the opaque products of specific thicknesses.
D, die sinking for the first time: make mold insert 2 shift out minimum die cavity 3 and obtain shaped article for the first time, but the product of this time moulding, be fixed on the mold insert 2 of rotating disc 1 and needn't take off, when dynamic model separates with cover half, dynamic model moves, rotating disc 1 rotation on the dynamic model makes first's product of injection formed and mold insert 2 rotate to next die cavity 3 position, prepares injection moulding next time.
E, matched moulds for the second time: the product and second die cavity, 3 matched moulds of moulding for the first time, with the first's product and second die cavity, 3 matched moulds of the moulding first time.
F, injecting glue for the second time:, the interior plastic cement of the first's product and second die cavity 3 is merged to second die cavity, 3 injecting glues behind the matched moulds.
G, cooling for the second time: make the product of moulding for the first time and the plastic cement cooling stack that is injected into second die cavity 3 be shaped to one, form the second portion product.
H, die sinking for the second time: the second portion product that stack is shaped to one takes out, and obtains final products, and the product inside that obtains does not like this have bubble, the transparency height, and the surface is depression not.
Wherein, after the h step, also comprise:
I, matched moulds for the third time: described rotating disc 1 is rotated to the 3rd die cavity 3 positions, make for the first time and the product and the 3rd die cavity 3 matched moulds of second moulding;
J, injecting glue for the third time: to the 3rd die cavity 3 injecting glues behind the matched moulds; The product of the first time and second moulding and the plastic cement in the 3rd die cavity 3 are merged.
K, cooling for the third time: make for the first time and the product of the moulding that superposes for the second time and the plastic cement cooling that is injected into the 3rd die cavity 3 once more stack be shaped to one, form the third part product.
L, die sinking for the third time: make mold insert 2 shift out the product that three type die cavities 3 obtain three stack moulding, when in injection moulding process, can be according to actual needs, a plurality of mold inserts 2 are set on rotating disc 1, the a plurality of die cavities 3 that cooperate with a plurality of mold inserts 2 are set in the cover half chamber simultaneously, carry out repeatedly laminated type injection moulding, finally obtain the specific thicknesses opaque products.
Operation principle of the present invention is: the product that will need the specific thicknesses of injection mo(u)lding earlier, be calculated as multilayer, from minimum volume to the end article volume, superposing type is laid at least two mold inserts 2 on rotating disc 1, be provided with the die cavity 3 that cooperates with mold insert 2 at the cover half die cavity, during use, each injection moulding folding mould, dynamic model rotating disc 1 can turn to special angle, whenever open dynamic model one time, 1 of rotating disc changes once automatically, wherein, when next injection moulding of back, a part of finished product of a preceding injection moulding does not need to take off, but cooperates injection moulding with next die cavity 3 together with mold insert 2, so reach manufactured goods to final thickness through repeatedly folding and spinning movement, each die sinking all has shaping finished product, shortens injection cycle, promoted output, solved mold base size super large, yield poorly, surface depression during the goods depanning of injection moulding, bad problems such as serious bubble and impurity have reduced production cost simultaneously.
The above only is a better embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
