    The invention relates to a device for making hollow articles by blowing in a mold, and more specifically to a device for opening and closing half-molds. The purpose of the invention is to reduce the time and energy costs of opening and closing the half-form. For this, the means for closing and opening each half-form is made in the form of a connecting rod pivotally connected with two levers, with the free end of one lever fixed to the half-form, and the free end of the other lever-on the cam axis of the mechanism for moving the means of closing and opening the half-form. The cam is rotatable and cylindrical with a guide groove on the side surface in which a roller pusher is mounted. The guide grooves in the cams at the upper and lower ends are made with straight sections, the axis of which is parallel to the axis of the cams. A longitudinal axis, hingedly connecting half-molds, is installed in the geometric center of the folding out of the half-molds. When the roller pushers move in the cam guide grooves, the latter rotate. By placing the longitudinal axis connecting the half-molds, the half-molds move during closing and opening along the shortest path in the geometric center of the half-molds, thereby reducing the time and energy required to move the half-forms. 1 hp f-ly, 4 ill.

    The invention relates to a device for the manufacture of hollow articles from thermoplastic, specifically to a device for closing and opening molds for blowing articles.
    The aim of the invention is to reduce the time and energy required to open and close the molds.
    FIG. Figure 1 shows the form, means of dp of its shrines and openings, the mechanism of their movement, general view; in fig. 2 is the same, in the closed position, a cross section; in fig. 3 - the same, in the position of the open form; 4 is a section A-A in FIG. 2
    The device consists of two half-molds 1 .. and 2, a hinge interconnected by means of a longitudinal axis 3, means for sharpening and opening half-molds.

    s
    The forms and the mechanism of their movement, including two cylindrical cams 4 and 5 with guide grooves 6 on the side surface J installed in the housing 7 with the possibility of rotation, roller pushers 8, located in the guide grooves 6 of the jaws and connected with the housing 7, and the drive movement The form of a hydraulic cylinder 9, the rod 10 of which is connected to the housing 7, The latter is pivotally mounted on the guides 11 Each means for closing and opening the half-form is made in the form of a connecting rod 12 hinged to the two-j arms and 13 and 14 ny onets t3 lever is mounted on the floor form and svobodnsh end of the lever. 14 is connected to the axis of the cam 4 or 5 of the movement mechanism. The longitudinal axis 3 of the mold is positioned relative to the means of rotation of the Loluformac, that it coincides with the geometric axis of the center of tilting of the half-molds 1 and 2 s. This provides a very short distance from -25 apex, resulting in a decrease in the time for opening and closing the half-forms and reducing the energy required dp move half molds
    The guide grooves 6 of the cams 4 and 5 d at the upper and lower ends are made with straight sections, the axis of which is parallel to the axis of the cams, which ensures smooth, but very accurate deceleration of the rotation of the molds and their. closing without impact,
    -The device works as follows.
    When closing the half-molds 1 and 2, the rod is 10 gi: cylinder 9, output cz cylinder- Q pa, moves body 7 downwards along guides 11, while roller pushers 8 located B of the guiding grooves 6 cams 4 and 5 slide down, turning The cams 4 and 5, which are connected to the ends of the levers 14, B, as a result, the lever system rotates: the levers 14, the levers 13 connected to the half-molds 1 and 2
    and a connecting rod 12 hinged to them. This converts the vertical movement of the rod 10 into a rotational movement of the means of closing and opening and half of them.
    When moving the roller pushers 8 up (the rod 10 of the hydraulic cylinder 9, enters the cylinder cavity), the half-molds 1 and 2 ”open.
