Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0022] as attached figure 2 As shown, a special-shaped workpiece 8 is generally in the shape of a hollow cylinder, and a circle of copper wire 81 is arranged in the middle of the cylinder.

[0023] as attached Figures 3 to 5 As shown, a secondary injection mold for a special-shaped workpiece 8 includes a male mold, a female mold 1, a first guide rail 2, a second guide rail 4, a base 5, a support 3, and an inner mold core 6.

[0024] When in the mold clamping state, the male mold and the female mold 1 form a cavity 11 .

[0025] as attached Figures 3 to 5 As shown, the first guide rail 2 is arranged on the male mold or the female mold 1 , th...

Abstract

The invention discloses a secondary injection molding die of a special-shaped workpiece. The secondary injection molding die comprises a male die and a female die which form a cavity in a die assembling state. the secondary injection molding die further comprises a first guide rail, a pedestal, a second guide rail, a base and an inner die core, wherein the first guide rail is arranged on the male die or the female die; the pedestal is arranged on the first guide rail and can slide along a long shaft direction of the first guide rail; the second guide rail is arranged on the pedestal; the base is arranged on the second guide rail and can slide along the long shaft direction of the second guide rail; and the inner die core is arranged on the base. An injection molding method by using the die comprises the following steps: positioning the workpiece on the inner die core; fixing an aluminum ring-type core on the inner die core; moving the base through the second guide rail to the inner die core to be directed at the cavity; moving the base through the first guide rail into the cavity of the inner die core in the male die or the female die; carrying out die assembling processing; opening the male die or the female die; moving the pedestal through the first guide rail to take the pedestal out of the cavity; moving the pedestal through the second guide rail to be away from the male die or the female die; and removing the aluminum ring-type core and the workpiece.

Description

technical field [0001] The invention relates to a secondary injection mold for special-shaped workpieces and an injection molding method using the mold. Background technique [0002] After the first injection molding process of some workpieces, the second injection molding process of the second special-shaped workpiece is required. like figure 1 and figure 2 Shaped workpieces shown. The workpiece is made of plastic as a whole, and the main structure is a hollow cylinder, but a circle of copper wires around its circumference is arranged in the middle of the cylinder. like figure 1 The product shown is a semi-finished product after the first injection molding. Since there is a layer of copper wire in the middle of the plastic, it can only be obtained after the second injection molding of the first special-shaped workpiece. figure 2 Finished product shown. [0003] Transferring from the first injection mold to the second injection mold of the second special-shaped workp...
