The invention relates to a ballpoint pen spring nib assembling device. The assembling device comprises an assembling platform, an assembling rotary disc and a rotary disc motor, wherein the edge of the assembling rotary disc is provided with conveying clamps for clamping nibs for conveying; and a nib feeding device for placing the nibs on the conveying clamps, a first nib detection device for detecting whether the nibs exist on the conveying clamps or not, a second nib detection device for detecting whether the nibs on the conveying clamps conform to the standard or not, a spring feeding device for placing springs on the nibs of the conveying clamps, a spring detecting device for detecting whether the springs are assembled in place or not, a waste discharging device for taking away unqualified nibs, a deformation device for extruding and deforming the side surfaces of the qualified nibs to limit the springs in the nibs, and a qualified product discharging device for taking away the deformed nibs are sequentially arranged at the position, close to the edge of the assembling rotary disc, of the assembling platform in the rotating direction. According to the technical scheme, the ballpoint pen spring nib assembling device improves the yield, improves the assembling efficiency and reduces the machining cost.

The invention relates to a mold locking device of a hollow plastic product forming machine, belonging to the field of a plastic product forming machine. The hollow plastic product forming machine comprises a left mold frame and a right mold frame, the mold locking device comprises a mold-locking actuating cylinder, a mold locking box and a mold-locking actuating cylinder grabbing mechanism, wherein the mold locking box comprises a mold locking box body, a cover plate, a first guide plate and a second guide plate; the mold-locking actuating cylinder grabbing mechanism comprises an upper actuating cylinder, an upper actuating cylinder seat plate, an upper engagement clamp block, a lower actuating cylinder, a lower actuating cylinder seat plate and a lower engagement clamp block; and the mold-locking actuating cylinder is horizontally arranged on the left mold frame, and cylinder column engagement teeth are formed at the surface of a mold-locking actuating cylinder column of the mold-locking actuating cylinder, at one end facing the mold locking box body. The mold locking device has the advantages that the closing effect of one pair of semi-molds can be ensured; the upper engagement clamp block and the lower engagement clamp block can be prevented from deflection to affect clamping forces on the mold-locking actuating cylinder column; the stability of vertical movement of the upper engagement clamp block and the lower engagement clamp block can be maintained in a long time; and the structure can be simplified, large locking forces for the mold-locking actuating cylinder column can be obtained with small mold locking forces, and electric energy can be saved.

The invention discloses a multi-functional wire slot and relates to the technical field of hub arrangement cable equipment, As the trace groove is connected at the corner, At first, that rotate plateis rotated, the rotation of the rotating plate also drives the limiting protrusion to rotate, until the retaining protrusions are fitted into the side spherical retaining grooves on the side panels, At this time, the engagement of the limit protrusion and the side spherical limit groove causes the rotate plate to remain fixed and opens the lower groove, at this time, the setting of the wire slot is complete, the two wire slots are vertically arranged, and the ports in the longitudinal direction of one wire slot are connected with the lower groove opened by the other wire slot, and then the wire operation is carried out.

The invention discloses a limiting device for injection mold processing. The device comprises a base ring arranged horizontally. The base ring is slidably provided with a plurality of frame plates. The frame plates are butted together to form a cylindrical structure. The cylindrical structure formed by the frame plates lacks an upper top surface. The inner wall of each frame plate is sealed and glued with a shaping capsule. The shaping capsule is a soft hollow capsule. A liquid storage cavity is arranged inside each frame. Sliding plates are sealed and slidably connected with the inside of theliquid storage cavities. The areas above the sliding plates in the liquid storage cavities and the inner of the shaping capsule are filled with magnetorheological fluid. The device has the advantagesthat after the shaping capsule is in good contact with a mold, a soft rod stops rotating and knocks on a slider, the internal pressure will push the slider to contact two electrical connection posts,a return spring and a solenoid coil are energized, the magnetorheological fluid becomes solid-like when feeling the magnetic field and cannot deform, thus the device can ensure a good clamping and limiting effect on the mold.

The invention relates to the technical field of automobile manufacturing and processing and discloses an electrophoresis conveying device, which comprises a fixing frame, wherein a driving part is fixedly arranged at the top end of the fixing frame and is connected with an upper-layer lifting tool through a hanging part, at least two sets of lower-layer lifting tools for lifting electrophoresis elements are fixedly arranged on the upper-layer lifting tool; balancing wood is separately arranged at two opposite side surfaces of the hanging part; a guide wheel is arranged at the tail end of the balancing wood; two strengthening guide rails for performing upper limiting of the guide wheel is suspended and fixedly arranged at the top end of the fixing frame; the guide wheel slides on the strengthening guide rails; the two strengthening guide rails are arranged at two sides of the hanging part and both extend in the horizontal conveying direction of the electrophoresis elements. The electrophoresis conveying device can be used for treating multiple sets of workpieces, the work pace can be well improved; by arranging the strengthening guide structure, the stably conveying of the lifting tools is facilitated.
