Embodiment Construction

[0012] The mold device provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] Please also refer to Figure 1 to Figure 5 , a mold device comprising a first mold core 10, a second mold core 20, a first sprue bushing 30, a second sprue bushing 40, a first sprue rotor 50 and a second sprue rotor 60, the first The sprue bushing 30 and the second sprue bushing 40 can pass through the first mold core 10 respectively, and the first sprue rotor 50 and the second sprue rotor 60 can respectively penetrate the second mold core 20 .

[0014] The first mold core 10 includes a first surface 102 and a third surface 104, the third surface 104 is arranged opposite to the first surface 102, and a first through hole 12 is opened in the first mold core 10, and the first through hole 12 is located in the first mold core 10. The middle part of the mold core 10 passes through the first surface 102 and the third surface 104...

Abstract

The invention relates to a mold device comprising a first mold insert, a second mold insert, a first sprue bushing and a second sprue bushing, wherein the first mold insert is provided with a first mold cavity and a second mold cavity and a first distribution passage and a second distribution passage, and the second mold insert is provided with a third mold cavity and a fourth mold cavity and a third distribution passage and a fourth distribution passage; and the first sprue bushing comprises a first sprue penetrating therein and a first sprue wall on which a first distribution groove is arranged, one end of the first distribution groove is communicated with the first sprue, the other end of the first distribution groove is communicated with the first distribution passage or the second distribution passage, the second sprue bushing comprises a second sprue penetrating therein and a second sprue wall on which a second distribution groove and a third distribution groove are arranged, the second distribution groove is connected with the second sprue and the first distribution passage, and the third groove is connected with the second sprue and the second distribution passage. Compared with the prior art, the mold device conveniently realizes the selective molding of each mold cavity.

Description

technical field [0001] The invention relates to a mold device, in particular to a mold device with multiple mold cavities. Background technique [0002] The mold device is an important tool for injection molding products. A mold device often has multiple cavities, that is, one mold has multiple cavities. Each mold cavity is connected with a runner, each runner is connected with a sprue (the sprue is provided by the sprue bushing), and the sprue is connected with an injection machine. During injection molding, the injection material is added to the barrel of the injection machine, heated to a molten state, driven by the screw or plunger of the injection machine, enters the nozzle through the nozzle of the injection machine, and is divided into each flow channel, thereby into each cavity. [0003] Usually, one set of mold sets corresponds to the molding of one product. In order to produce different products, multiple sets of mold sets need to be produced accordingly. The mo...
