Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Examples

As shown in fig. 6 to 10, the application provides a refrigerator panel mold, which comprises an upper mold and a lower mold, wherein the upper mold and the lower mold are respectively provided with a front mold frame 10 and a rear mold frame 11, a cavity part 1 is arranged in the front mold frame 10, and a core part 3 and an ejection part are arranged in the rear mold frame 11. The cavity part 1 and the core part 3 are inclined at a set angle along the vertical direction so that the parting line is at the root of the panel product 2, and the ejection part is inclined at a set angle along the vertical direction, wherein the set angle is 37 degrees in the embodiment.

The ejection part comprises an ejector plate which is arranged on an ejection oil cylinder 9, and the ejector plate is provided with a reset rod 6, an inclined ejector 5 and an ejector rod 4. The ejector plate comprises an upper ejector plate 7 and a lower ejector plate 8 which are arranged up and down. The ejector pin plate is provided with a plurality of ejector pins 4. The reset levers 6 are provided one at each of four corners of the core portion 3.

A main runner is provided in the front mold frame 10. The core part 3 is provided with rib and hook shapes. The top of the front mould frame 10 is provided with a front mould frame bottom plate, the bottom of the rear mould frame 11 is provided with a rear mould frame bottom plate, and the front mould frame bottom plate is connected with the injection molding machine in the vertical direction.

2 rotatory 37 backs of panel product, die cavity part 1 does not have the overhead kick, can normally the demolding, as shown in fig. 4, 5, parting line PL is at the root, product appearance part does not have the parting line, but core part 3 is the overhead kick like this, the product is along the unable demolding of conventional vertical direction, this application utilizes outside oil cylinder drive, ejector pin 4, 5 carry out the 3 overhead kick drawing of patterns of 2 core parts of panel product along 37 liftouts and resets of vertical direction, thereby solve the problem that the product parting line influences the product appearance on the R angle tangent point.

The use process of the mould comprises the following steps:

under the drive of a workbench of an injection molding machine, a cavity part 1 and a core part 3 are separated, when the demolding of a panel product 2 and the cavity part 1 is completed, because the shape of the cavity part 1 of the product is simple, the shape of a rib and a clamping hook of the core part 3 is more complex, and the packing force is larger than that of the cavity, the product is left in the core part 3; the ejector rod 4 and the inclined ejector 5 are assembled on the ejector plate and are ejected out along the direction (the included angle of the vertical direction is 37 degrees) of the reset rod 6 under the action of the ejection oil cylinder 9, so that the demoulding of the panel product 2 and the sprue is completed; the panel product 2 and the sprue are taken out by a manipulator of the injection molding machine, and under the action of an ejection oil cylinder 9, an ejector rod 4 and an inclined ejector 5 which are assembled on an ejector plate return along the direction (the included angle of the vertical direction is 37 degrees) of a reset rod 6; and (3) injection molding and die assembly are carried out, and the die cavity part 1 and the core part 3 are matched to finish one production cycle of the panel product 2.
