Problems solved by technology

Three-sided core pulling will significantly increase the volume of the mold, increase the production cost of the mold, and also reduce production efficiency. At present, there is no demoulding method and mold that adopts two-sided core pulling for the integrated planetary carrier with three planetary wheels.

Embodiment

[0023] The present invention provides a kind of one-piece planet carrier mold with three planet wheels, processing method and the planet carrier processed by this method, such as figure 1 and 2 As shown, the planetary carrier 10 of the present invention with three planetary gears is similar to the planetary carrier in the prior art, including three outer ring gears 11 for setting the planetary gears, a circular internal tooth positioned at the center of the planetary carrier Ring 12, three fixed columns 15 connecting the upper cover 13 and the lower cover 14 of the planetary carrier, and the upper cover 13 and the lower cover 14 are located at the center of the outer ring gear 11 and are provided with two shaft holes for installing the rotation shaft of the planetary wheel 16. The three fixed columns 15 are respectively the first fixed column 151, the second fixed column 152 and the third fixed column 153. The difference is that the outer surface 1511 of the first fixed column...

Abstract

The invention relates to an integrated mold of a planet carrier which is a planet carrier possessing three planetary gears. The mold is characterized in that the mold comprises a fixed mold and a mobile mold; a first slide block and a second slide block are oppositely arranged between the fixed mold and the mobile mold and can mutually fit for forming a planet carrier cavity; the first slide block comprises one or multiple wedge-shaped projection blocks arranged in a parallel way, and the front end of each projection block is provided with a first groove; two second grooves respectively disposed at two sides of the end of each projection block are arranged on the first slide block; the second slide block is provided with one or multiple U-shaped grooves arranged in a parallel way and fitting with the projection blocks; the rear bottom of each U-shaped groove is in the shape of an arc; two projections disposed at two sides of the front top of each U-shaped groove are arranged on the second slide block; and the two lateral surfaces of each U-shaped groove and the two lateral surfaces of each projection are all flat. When the first slide block meets the second slide block, the projection blocks insert into the U-shaped grooves, and the two lateral surface of each U-shaped groove is tangent to the two lateral surfaces of the corresponding projection block, and when the fixed mold and the mobile mold are separated, the first slide block and the second slide block are separated.

Description

【Technical field】 [0001] The invention belongs to the technical field of mold design and manufacture, and relates to an integrated planetary frame mold, a processing method and a planetary frame. 【Background technique】 [0002] The planetary carrier is one of the main components of the planetary gear transmission. The planetary wheel shaft or bearing is installed on the planetary carrier. The integral planetary carrier has good rigidity. The tiny planetary carrier is more difficult to cut and process, so the planetary carrier made of plastic material is gradually replaced by the planetary carrier made of metal material. The plastic planetary carrier needs to adopt the core pulling method when the injection molding is demolded. For the planetary carrier with three planetary wheels The one-piece planet carrier made of plastic needs to adopt the method of three-sided core pulling when the injection molding is demoulded. Three-sided core pulling will significantly increase the ...
