The invention discloses a novel plastic injection mould of an oblique core-pulling mechanism. A support plate is arranged on a movable mould base plate, wherein a movable mould plate is arranged on the support plate; a cavity plate is arranged on the movable mould plate; a fixed module base plate is arranged on the cavity plate; a swinging rod is arranged in a cavity body and is articulated in the support plate; a pin shaft I is arranged on one side of an oblique pin; the pin shaft I is connected with the oblique pin in a long circular sliding slot of the swinging rod in a sliding manner; the swinging rod is connected with a connection rod; the other end of the connection rod is articulated with a sliding block; a guide rail rod penetrates through the sliding block; a bracket I is arranged on one side of the cavity plate and is articulated with a bent pin swinging hook; a bracket II is arranged on one side of the movable mould plate; a pin shaft II is arranged at the end of the bracket II and is located in an oblique guide slot of the bent pin swinging hook; a convex mould is arranged on the movable mould plate; an oblique rod at the upper end of the oblique pin is arranged in an oblique hole of the movable mould plate; a pushing rod is arranged under a plastic part generation tank; a pushing plate fixing plate is arranged under the pushing rod; a pushing plate is arranged in the pushing plate fixing plate. According to the novel plastic injection mould of the oblique core-pulling mechanism, the swinging rod-bent pin structure is used for obliquely pulling the core; the structure is simple and is liable to manufacture, great in pulling force and adjustable in core-pulling distance.

The invention provides a groove type embedded part, including groove steel and anchor legs. The two end faces of the groove steel in the direction of the depth of grooving of the groove steel correspondingly form a first end face and a second end face, and groove openings of the grooving on the groove steel are located on the first end face; the second end face is provided with one or more anchorlegs in a fastening mode; when a plurality of anchor legs exist, the anchor legs are arranged in sequence in the direction of the length of the groove steel; the anchor legs comprise first componentsand second components, the first components and the second components can move relative to each other at least along the length of the anchor legs; and according to the two ends of the first components in the direction of length extension, one end is connected to the second end face, and the other end is connected with the second components. According to the groove type embedded part, total lengths of the anchor legs can be adjusted to adapt to different working conditions and bring better stress. In addition, the rapid adjustment of the levelness of the groove steel can be achieved.

The invention discloses a binding fastening device consisting of a movable part, a drawing rod and a fixed part, wherein the movable part is rotationally connected to the fixed part; the drawing rod is rotationally connected to the movable part; the central axis of the rotation of the drawing rod relative to the movable part is parallel to the central axis of the rotation of the movable part relative to the fixed part; the drawing rod is rotationally connected with a drawing ring; and the fixed part is rotationally connected with a fixed ring. When the binding fastening device is in use, one end of a chain is fastened and connected to the fixed ring; the other end of the chain is fastened and connected to the drawing ring after a to-be-fixed object is bound by the chain; the movable part is rotated toward the direction away from the fixed part; and the movable part draws and pulls the chain through the drawing rod to tension the chain so as to improve the binding firmness of the chain.

The invention provides a channel-type embedded part, which includes channel steel and anchor legs; The notch is located on the first end surface; one or more anchor legs are fastened on the second end surface; when there are multiple anchor legs, the multiple anchor legs are arranged in sequence along the extending direction of the channel steel; the anchor legs include the first A member and a second member, the first member and the second member can at least move relative to each other along the length extension direction of the anchor leg; of the two ends of the first member along the length extension direction, one end is connected to the second end surface, and the other One end is connected with the second member. The invention can adjust the total length of the anchor legs, so as to adapt to different working conditions, bring better force bearing, and also realize rapid adjustment of the levelness of the channel steel.
