Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, one embodiment provided by the present utility model is: the utility model provides a rotational moulding mould rotatory slider advance and retreat structure, includes apron 100, rotating member 200, two sliders 300, outer movable block 400, apron 100 install in the top of outer movable block 400, rotating member 200 holding in outer movable block 400 just the top wears to locate on the apron 100, have two accommodation grooves 410 on the outer movable block 400, two arc recess 210 have been seted up to the symmetry on the rotating member 200, two sliders 300 slip holding in two accommodation grooves 410 and the projection 310 holding at top in arc recess 210.

Further, the cover plate 100 has a stopper 110 thereon.

Further, the two stoppers 110 are symmetrically disposed on the cover plate 100.

Further, the cover plate 100 is provided with a plurality of limiting holes 120, and the limiting holes 120 are provided with detachable limiting pieces 130.

Further, the outer piston 400 has a hollow structure.

Further, the surface of the slider 300 away from the inner layer of the outer loose piece 400 is a curved surface layer 320.

When the product needs to be demolded, the rotating piece 200 is manually rotated anticlockwise, the two arc-shaped grooves 210 on the rotating piece 200 drive the convex columns 310 on the two sliding blocks 300 to move in the two accommodating grooves 410, and then the convex columns 310 drive the two sliding blocks 300 to move, under the combined action of the two accommodating grooves 410 on the outer movable block 400, the two sliding blocks 300 are moved out of the two accommodating grooves 410, and after being mutually abutted with the product in the die, the product is ejected out of the rotational molding die, so that the demolding of the product is completed.

Like this, a rotational moulding mould rotatory slider advance and retreat structure, through the cooperation setting of apron 100, rotating member 200, two sliders 300, outer movable block 400, anticlockwise rotatory rotating member 200, two sliders 300 make two sliders 300 only can follow the horizontal direction motion under the combined action of two accommodation grooves 410 on rotating member 200 arc wall 210 and outer movable block 400, thereby realize two sliders 300 follow the business turn over of two accommodation grooves 410, realize the smooth drawing of patterns of moulded product, need not to carry out the dismantlement and the installation of a plurality of parts, the drawing of patterns process is more simple high-efficient, production efficiency has been improved.

Further, in order to control the rotation angle of the rotating member 200, the cover plate 100 has two stoppers 110, which are symmetrically disposed on the cover plate 100.

In this way, the two stoppers 110 are mounted at the preset positions on the cover plate 100, in the initial state, the rotating wall 220 of the rotating member 200 is abutted with one of the stoppers 110, when demolding is required, the rotating wall 220 of the rotating member 200 is rotated until the rotating wall 220 is abutted with the other stopper 110, at this time, the two sliding blocks 300 are moved out to the maximum moving-out positions, and the sliding blocks 300 are not moved out to the excessive positions due to the excessive rotation angle of the rotating member 200, so that the extrusion force of the products in the mold is excessive, and the products are damaged.

Further, in order to better control the rotation position of the rotating member 200, the cover plate 100 is provided with a plurality of limiting holes 120, and the limiting holes 120 are provided with detachable limiting members 130.

Thus, when the rotary member 200 rotates to the preset position, the limiting member 130 is inserted into the preset limiting hole 120, so that the rotary wall 220 of the rotary member 200 is located between the limiting member 130 and the stop member 110 and cannot rotate, the rotating position and the rotating angle of the rotary member 200 are well fixed, and an operator does not need to control the rotary member 200 all the time, so that other works can be performed.

Further, the number of the limiting holes 120 is plural, and the limiting member 130 can be inserted into the adapted limiting hole 120 according to different angles of rotation of the rotating member 200. The stopper 130 may be a bolt.

Further, the outer piston 400 has a hollow structure. It is convenient to accommodate the rotary member 200 in the outer piston 400.

Thus, the surface of the slider 300 away from the inner layer of the outer loose piece 400 is a curved surface layer 320, which can be conveniently abutted against the demolding product.

Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
