Description

  The present invention relates to a mold configuration for reducing heat loss particularly in a mold having a temperature adjustable, which is used when injection molding a thermoplastic resin or the like.

  Molding molds used in injection molding machines reduce the surface defects of the molded product due to rapid cooling of the resin by warming the mold during injection filling with molten resin, and the cooling process of the molded product In order to shorten the operating cycle of the injection molding machine by quickly lowering the temperature, the mold is forcibly heated and cooled. Since the mold can withstand a large mold clamping force corresponding to the injection resin pressure of the molten resin, the conventional mold is provided with a plurality of through-holes close to the cavity surface of the mold having a single rigid structure. The structure used as a heat medium passage when heating and cooling the mold was common, but it was difficult to process a plurality of long through holes in a heavy metal mold, and the amount of heat carried by the corner heat medium Is deprived of the large heat capacity of the mold, the time of repeated heating and cooling processes becomes long, and there is a problem that the operating cycle cannot be reduced, so that processing is easy and avoiding loss of heat Various ideas have been proposed for the mold structure aiming at the above.

  Therefore, the one shown in FIG. 19 has been conventionally proposed. (For example, patent document 1) As shown in FIG. 19, the part which forms the cavity of a metal mold | die is made into the nest | insert 91, and the liquid passages 93 and 95 with which a heat medium passes to the surface side which fits the metal mold | die base | substrate 90 of the nest | insert 91 are shown. 96, and at the same time, the reinforcing rib 92 is provided on the same fitting surface to increase the strength of the insert 91, and the surface on which the insert 91 on the mold base 90 side is fitted is recessed along the reinforcing rib 92 of the insert 91, The contact surface between the mold base 90 and the insert 91 has a structure in which gypsum 94 is sandwiched as a caulking material, and the resin is filled by passing a high-temperature heating medium through the liquid passages 93, 95, and 96 provided in the insert 91. The front insert 91 is heated to reduce defects on the surface of the molded product 97, and the temperature is switched to a low-temperature heat medium to rapidly cool the molded product 97 after resin filling, thereby increasing the strength of the insert 91 by the reinforcing ribs 92. Of the mold base 90 and the insert 91 The large resin pressure in cushion by gypsum 94 applied to the nest 91 equally is intended to convey the mold base 90.

  However, the above-described conventional mold is difficult to process the insert 91 when the molded product is a deep product, and even when the molded product 97 is a flat product, the processing of the heat medium passage is complicated and the mold cost is low. In addition, even if gypsum 94 as a caulking material is filled between the insert 91 and the mold base 90, the gap between the two is not completely filled, and the heat medium leaks between the heat medium passages. And the lateral displacement of the cavity surface of the insert 91 due to the resin pressure in the cavity is likely to occur (if the cavity surface of the insert is displaced, a molded product in which the front surface and the back surface are misaligned), There is a problem with the quality of the molded product.

Furthermore, by coating the inside of the fixed side mold 2 and the movable side mold 6 with the heat insulating material 12, the fixed side mold 2 and the movable side mold can be used in the case of repeated heating and cooling in a short time. Since the amount of heat transferred to 6 is reduced, there is a great energy saving effect.

  The heat medium supply port 20a or the heat medium discharge port 21a is formed in the cavity 11 side on the upper and lower surfaces of the fixed-side mold body 3 or the movable-side mold body 7, and the heat insulating material 12 is the back surface on the side surface of the cavity 11. Since the side surfaces of the cavity 11 of the fixed mold body 3 and the movable mold body 7 are heated and cooled more uniformly, deformation due to the temperature distribution difference can be reduced. .

  Next, Embodiment 2 of the present invention will be described with reference to FIGS. 4 is a longitudinal sectional view of a molding die schematically showing a peripheral device according to the second embodiment, FIG. 5 is a detailed longitudinal sectional view of the stationary side mold of FIG. 4, and FIG. 6 is a stationary side of FIG. It is BB sectional drawing seen from the attachment side of a metal mold body. 7 is a partially enlarged longitudinal sectional view showing the heat medium passage of the fixed side mold of FIG. 5, and FIG. 8 is a sectional view taken along the line CC in FIG. 7 along the auxiliary line (dashed line). 5 to 8, the receiving bush 41, the eject bar 43 and the like are not shown. 4 to 8, the same parts as those of the first embodiment (FIGS. 1 to 3) are denoted by the same reference numerals.

  Example 2 is an example in which high temperature water is used on the high temperature side and low temperature water is used on the low temperature side as the heat medium. The difference from the first embodiment is that the air supply pipe 57 and the operation opening / closing valve 58 for removing steam and the like are not required, the heat insulating filling member 13 is filled instead of the heat insulating material 12, and each heat medium is Is recovered in each of the recovery tanks 70 and 73 and recirculated. Hereinafter, differences from the first embodiment will be mainly described.

As shown in FIGS. 4, 5, and 6, the shapes of the fixed mold 2, the movable mold 6, and the like are almost the same as those of the first embodiment (FIGS. 1, 2, and 3) (fixed mold). If the main body 3, the movable mold main body 7 and the like are made of casting, the casting material may be exactly the same). Then, a heating medium supply opening 20b and the heating medium discharge port 21b is, that it is formed in the cavity 11 side of the upper and lower surfaces of the stationary mold-defining member 3 or the movable mold-defining member 7 is different.

  The reinforcing ribs 10 of the fixed side mold body 3 and the movable side mold body 7 are arranged in the form of a cross like the first embodiment, and the heat medium supply port 20b, the reinforcing rib penetration paths 23a, 23b, 23c, heat The medium discharge ports 21b are also provided in three rows in the vertical direction. And instead of the heat insulating material 12 in Example 1, it surrounds with the internal peripheral surface of the stationary-side metal mold | die body 3 or the movable-side metal mold | die body 7, the cross-shaped reinforcement rib 10, and the attachment member 4 or the attachment member 8. FIG. In the space, the heat insulating filling members 13, 13 a, 13 b, 13 c and 13 d are provided by being attached to the attachment member 4 or the attachment member 8 in three rows.

  The heat insulating filling members 13, 13 a, 13 b, 13 c, and 13 d are provided so that the side surfaces thereof are almost in close contact with both surfaces of the reinforcing rib 10 and the inner surface of the fixed-side mold body 3. In-cavity passages 24a, 24b, 24c, and 24d are formed on the back surface of the side mold body 3 on the cavity 11 side.

  And the horizontal (horizontal direction) cross-sectional area which cross | intersects the flow direction of the heat medium in this channel | path 24a, 24b, 24c, 24d and the reinforcement rib penetration path 23a, 23b, 23c is formed so that all may become the same. . In this way, since the cross-sectional area of the passage of the heating medium is not changed, the passing speed of the heating medium becomes substantially constant, so that the heating medium and the back surface of the stationary mold body 3 on the cavity 11 side are exchanged. The amount of heat is approximately averaged, and the temperature unevenness of the surface of the cavity 11 can be reduced.

  That is, as shown in FIGS. 7 and 8, the interval between the reinforcing ribs 10 in the fixed-side mold body 3, that is, the width of the in-cavity passage 24a and the in-cavity passage 24b is W2, and the fixed-side mold body 3 The distance between the back surface and the top surface of the heat insulating filling member 13a, that is, the height of the intracavity passage 24a is S1, the height of the intracavity passage 24b is S3, the lateral width of the reinforcing rib penetration passage 23a of the reinforcing rib 10 is W1, and the vertical width. , S2 and the reinforcing rib penetration path 23b is W1 and the vertical width is S4, so that each of the heat-insulating buried members 13a, 13b, 13c, 13d is W2 × S1 = W1 × S2 = W2 × S3. By determining the height of the top surface, the cross-sectional area of the heat medium passage in the stationary mold body 3 is not changed. Similarly, in the movable side mold 6, the heat-insulating filling members 13 a, 13 b, 13 c, and 13 d are disposed between the movable side mold body 7 and the reinforcing rib 10, and the intracavity passages 24 a, 24 b, 24c and 24d are formed.

  Thus, since the heat insulating filling members 13a, 13b, 13c, and 13d cover portions other than the heat medium passage of the stationary mold body 3 and the reinforcing rib 10, the portions other than the heat medium passage are heated by the heat medium. It is difficult to be cooled and the heat quantity of the heat medium can be used effectively. When the back surface of the cavity 11 is particularly desired to be heated and cooled, the cross-sectional areas of the intracavity passage 24a near the heat medium supply port 20b and the intracavity passage 24d near the heat medium discharge port 21b are reduced, and the other heat medium passages are used. By changing the shape of the top surface of each of the heat insulating filling members 13a, 13b, 13c, 13d, such as by increasing the cross-sectional area, it is possible to arbitrarily determine the flow rate and flow of the heat medium.
