The invention discloses a master mold angled core-pulling structure. The master mold angled core-pulling structure is used for molding a slope and an inclined hole forming an inclined angle with a vertical direction in a mold. The master mold angled core-pulling structure comprises 1, a first slide block main body with an inclined hole, wherein one side of the first slide block main body is provided with a first vertical plane and a first inclined plane, 2, a second slide block main body, wherein one side of the second slide block main body is connected to the first slide block main body and the other side of the second slide block main body contacts a male mold core, 3, a sliding block insert core, wherein the sliding block insert core is arranged in a female mold core and is slidingly arranged at the other side of the first slide block main body, one end of the sliding block insert core molds a slope and an inclined hole of a product and an elastic component is arranged between the sliding block insert core and the second slide block main body, 4, a stirring block, wherein one end of the stirring block is fixed in a master mold plate and the other end of the stirring block is arranged in the inclined hole of the first slide block main body, and 5, a sliding block positioning block, wherein one end of the sliding block positioning block is fixed in the master mold plate and one side of the sliding block positioning block is provided with a second vertical plane and a second inclined plane. The master mold angled core-pulling structure can be used for a plurality of mold structures and can be released from an inclined plane and an inclined hole forming a large inclined angle with the vertical direction.
Description
【Technical field】 [0001] The invention relates to a mold structure, in particular to an oblique core-pulling structure of a mother mold. 【Background technique】 [0002] Plastic products are formed by injection molding of plastic molds, and plastic products are often used in electronic products, communication products and consumer products. In recent years, with the widespread use of electronic products, communication products and consumer products, plastic molds have also become the subject of extensive research. [0003] In order to meet the needs of design, there will be inclined surfaces and oblique holes on the plastic products that are inclined to the vertical direction, and oblique core pulling is required for demoulding. In the prior art, the three-plate mold is used to open the mold at the stripping plate first, and the oblique core-pulling structure of the mother mold will first pull out the inclined surface and the inclined hole under the elastic force of the spri...
