Problems solved by technology

The current molding molds for satellite receiver shells have a one-out two-piece structure, and two products can be obtained by opening the mold at one time, so there are two integrally formed cores, and the side of the core is equipped with a material inlet, which is impacted by high-temperature molten aluminum The side of the core will wear out after a long time. If the die loss exceeds the tolerance requirement, the core will be scrapped. At present, a pair of molds can only produce 20,000 dies. Later, the wear on the side of the core exceeds the tolerance requirement, resulting in the production of The product does not meet the requirements, and the core needs to be replaced, accompanied by an increase in production costs

Embodiment 1

[0019] Embodiment one, combining figure 1 and figure 2 shown. The two cores 2 are exactly the same, the longitudinal sections of the tails of the two cores 2 are square, and the mounting base 3 is provided with an open groove, and the two cores 2 are arranged side by side and tightly fitted in the opening groove of the mounting base 3 . The open slot can be called a dustpan shape; when the side wear of the core 2 exceeds the tolerance requirement, the two cores 2 are pulled out and rotated 90° and inserted back into the open slot, and the other side of the core 2 faces Z Shaped sprue 1.2, to achieve angle change; two cores 2 can be rotated three times, using a new design structure, the core 2 can be used three times more than the existing technology, which greatly reduces the production cost, and at the same time extends the core 2 and the service life of the mold.

Embodiment 2

[0020] Embodiment two, combining figure 1 and image 3 shown. The two cores 2 are completely consistent, the tails of the two cores 2 are gears 2.1, and the two gears 2.1 are meshed and interlocked through the free gear 2.2 and placed in the mounting seat 3, and the free gear 2.2 is connected to the motor 2.3.

[0021] The gears 2.1 at the tails of the two cores 2 are respectively connected to a rotating shaft, and the rotating shaft cooperates with a bearing, and the bearing is installed in the mounting base 3 body, and the connecting shaft of the motor 2.3 is linked with the free gear 2.2 through a shaft coupling. The motor 2.3 drives the free gear 2.2 to rotate through the motor shaft, and the two gears 2.1 mesh with the free gear 2.2 to drive the two cores 2 to rotate. By controlling the rotation angle of the motor, multiple 90° angles of the core 2 are realized.

[0022] Described motor 2.3 is a stepper motor. The stepper motor converts the electrical pulse signal into...

Abstract

The invention discloses a shell forming mould of a satellite receiver. The shell forming mould comprises a lower mould, a lower mould assembly and a mould cavity, wherein the lower mould and the lower mould assembly can form a mould cavity, and the mould cavity is internally provided with two cores of a forming shell; the shell forming mould is characterized in that the two cores are manufactured respectively and are installed in an installing base respectively. The cores are designed respectively, and the two cores can both rotate to adjust the position, therefore, when the abrasion of one side surface of one of the cores caused by impact of a casting liquid exceeds a tolerance requirement, the cores can rotate by 90 degrees; the sides, which face to a casting channel, of the cores after the position of the cores is rotated does not suffer from the impact of the casting liquid, therefore, the tolerance requirement is fitted, the cores can be reused, and so on, after the cores rotate for three times, that is, impacts of the casting liquid to the four side surfaces of the cores all exceed the tolerance requirement, the whole core finally scraps; the cores rotate for three times, compared with the core in the prior art, the service life can be prolong by three times, the manufacturing cost is greatly reduced, and meanwhile, the service lives of the cores and the mould are prolonged. The shell forming mould provided by the invention belongs to the technical field of moulds.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a molding die for a satellite receiver shell with a longer service life. Background technique [0002] The satellite receiver shell forming mold includes a lower mold, a lower mold, a mold cavity and an insert. The core is the main insert for forming the shell. The shell is installed on the mold frame of the lower mold through a fixing seat, and the core is located in the mold cavity. The current molding molds for satellite receiver shells have a structure of one out and two out, and two products can be obtained by opening the mold at one time, so there are two integrally formed cores, and the side of the core is provided with a material inlet, which is impacted by high-temperature molten aluminum The side of the core will wear out after a long time. If the die loss exceeds the tolerance requirement, the core will be scrapped. At present, a pair of molds can only produce 20,000 di...
