Detailed Description

The utility model provides an injection mold for producing chine. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

Referring to fig. 3-4, an injection mold for producing spines comprises a movable mold 1 and a fixed mold 2.

The mould comprises a first parting plane 3 and a second parting plane 4. The first parting surface 3 is the top surface of the base towards one side of the vertical plate, and the second parting surface 4 is the plane where the top surface of the vertical plate is located.

The top of the movable mold 1 is an injection molding area of the movable mold 1, and the injection molding area of the movable mold 1 is rectangular. The injection molding area of the movable mold 1 is provided with a cavity of the movable mold 1, and the cavity of the movable mold 1 comprises a plurality of movable mold backbone cavities 5 which are arranged in parallel. Two corners of the first parting surface 3 in the injection molding area of the movable mold 1 are provided with coordination convex blocks 6.

The fixed die 2 is matched with the movable die 1 to be provided with a fixed die spine cavity 7.

The design can be used for producing two or more spine injection-molded parts by injection molding at one time, and the production efficiency can be improved. The selection of the first parting surface 3 and the second parting surface 4 is beneficial to parting and material taking, and the development cost of the die is also reduced.

The number of the movable mold spine cavities 5 is 2. A gate 8 is provided in the first parting surface 3, said gate 8 being provided on the midline between the 2 movable mold backbone cavities 5. A runner a9 is provided along the midline between the movable mold spine mold cavity 5, the runner a9 is connected to the gate 8, and the runner a9 is a sprue. The first parting surface 3 is provided with a pouring channel B and a pouring channel C, the pouring channel B and the pouring channel C are symmetrically arranged on two sides of the pouring channel A9, and the pouring channel B and the pouring channel C are respectively connected with the pouring channel A9 and the movable mold backbone cavity 5.

And a U-shaped exhaust passage 10 is arranged on the first parting surface 3 of the fixed die 2 along the outer side of the die cavity corresponding to the base, and the U-shaped exhaust passages 10 are sequentially connected.
