    The mould used in manufacturing moulded articles is cooled by cooling fluid flowing along a cooling passage (10, 12, 14) in the mould. In order to concentrate the cooling effect in a desired central region (10) of the cooling passage, and exit portion (12) of the passage is enlarged relative to the central region (10). If desired, the entrance portion (14) may also be enlarged to further concentrate the cooling effect.

    专利说明:

    The invention relates to the construction and building materials, namely, molded glass products, in particular to the form for the manufacture of glass products.
    The aim of the invention is to increase the cooling efficiency.
    FIG. 1 cooling channel form in the first embodiment, the cut; in fig. 2 is a graph showing heat removal along the cooling channel of FIG. one; in fig. 3 - the cooling channel of the form according to the second embodiment, the section; in fig. 4 is a graph showing the heat removal along the cooling channel of FIG. 3; in fig. 5 - the form according to the second variant, longitudinal section. The cooling channel contains a central part 1 of circular cross section with the same cross-sectional area. The central part 1 connects the inlet part 2 of the cooling channel with the outlet part 3. Thus, the cooling medium can flow in the direction of arrow L from the inlet to the central part. The outlet part 3 has a circular section with the same cross-sectional area, a larger cross-sectional area of the central part 1.
    The cooling effect depends on the implementation of the chilled channel (Figures 1, 3 and 5). The entrance-part 2 of the channel can have a circular cross section and the same cross-sectional area equal to the central part 1 (Fig. 1), and the same cross-sectional area, which is larger than the cross-sectional area of the central part 1 (Fig. 3). The proposed form has at least one cooling channel, which extends longitudinally, through which the cooling medium passes, cooling the form. The central part 1 passes through the central zone of the mold, and the output part 3 passes through the end portion of the mold, the output part 3 being located in such a way that the cooling medium can pass from the central part 1 to the output part 3.
    FIG. Figure 2 shows a graph of heat removal as a function of the length of the cooling channel of figure 1 starting from the inlet part 2. Although the flow of cooling medium (indicated by arrow A), which passes through the cooling channel, is even, the amount of heat removed decreases when air moves through the channel. as the air heats up and therefore the drop
    the temperature between the air and the walls of the cooling channel decreases. The graph in FIG. 2 shows that the heat removal in the inlet part 2 is reduced (curve 4). On the transition between the central part 1 and the output part 3, a very rapid decrease in heat removal is observed (section 5); in the output part 3, heat removal is also
    decreases (region 6). If we compare the broken line with the solid line 4, 5, 6, we can see that the cooling channel in the first embodiment provides an improved cooling effect in the central part 1 and in the entrance part 2, but a reduced cooling effect in the output part 3.
    FIG. 4 shows a plot of heat removal versus the length of the cooling channel of FIG. 3. The mold interacts with the pallet 7 lying on the base plate 8 and has a cavity 9 in the shape of a bottle. The cooling channel 2.1, 5 3 runs along the shape and parallel to the longitudinal axis of the cavity 9, receiving the cooling medium through the hole 10 in the base plate 8 in the direction of the arrow A. The plot 11 of the graph shows 0 the cooling effect in the inlet part 2, the portion 12 - in the central part 1 and section 13 in the output part 3. The sections 14 and 15 show, respectively, rapid changes in the cooling effect that occur at the transitions between the input part 2 and the central part 1 and between the central part 1 and the output part. compare broken and solid l Nij graph shows that the cooling effect in the input portion 2 is reduced in the central part of the channel increases and the outlet portion is also reduced.
    The cooling effect of the passing cooling medium is concentrated in the central part of the cooling channel without the use of insulating materials.
    Channel 2, 1.3 for cooling medium usually extends parallel to the longitudinal axis of the cavity 9 of the mold. The central part 1 of the channel is located opposite the cylindrical central part of the blade 9, which forms the central part of the bottle, the entrance

    the part 2 and the exit part 3 are opposite the end parts of the cavity 9. One end part is the part of the base that interacts with the pallet 7 during the formation of the bottom part of the butyrka, the input part 2 being located opposite this end part. The other front part, opposite to which the outlet part 3 is located, is intended to form the neck of the bottle.
