Abstract

(57) [Abstract] [Purpose] When supplying steam to the fixed-side frame mold of the Styrofoam molding die, the number of fixed-side frame molds can be increased by detachably attaching the ventilation passages and partition plates in the fixed-side box frame. The air passage can be replaced according to the above, and the waste of the manufacturing cost and the work due to the replacement of the entire fixed side box as in the past can be omitted. [Structure] The mounting wall 4 is bent and formed at a fixed distance from the inner wall of the fixed-side box frame 1 on the steam inlet 2 side and the inner wall of the steam outlet 3 side. A partition plate 5 detachably attached by bolts and nuts 9 to both ends of an air passage 8 whose upper surface is open to both attachment walls 4 is detachably bolted and nuts 6. Ventilation ports 10 are provided in the partition plate 5 where both ends of the ventilation passage 8 are attached. A bolt and nut stopper 12 is attached to the top plate 11 so that the upper surface of the air passage 8 can be attached and detached. A long hole 14 having the same width as the width of the ventilation passage 8 is provided in the top plate 11 corresponding to the back side of the fixed side frame die 13.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steam supply device for supplying steam from a fixed side box of a Styrofoam molding die to the back side of a fixed side frame die.

[0002]

[Prior art]

 Conventionally, when supplying steam to a Styrofoam molding die, steam was supplied to the entire fixed-side box frame to heat the fixed-side frame mold. The amount of steam consumed to raise the temperature of the side box frame itself was larger, and it was very wasteful.

Therefore, the ventilation path is fixed in the fixed side box, and steam is supplied from the ventilation path to the back side of the fixed side frame die to eliminate waste of the steam amount. The number of roads was also different, so many types of fixed boxes had to be manufactured and replaced each time, resulting in high manufacturing costs and very troublesome replacement work.

[0004]

[Problems to be solved by the device]

 From the above points, the present invention does not change the fixed side box even if the number of fixed side frame molds changes, and it is only necessary to replace the number of ventilation frames according to the number of fixed side frame molds. It is intended to provide a steam supply device for a Styrofoam molding die that can reduce the manufacturing cost and improve the work efficiency.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the device of the present invention is such that a partition plate is detachably mounted in the fixed-side box frame at intervals from the inner wall of the fixed-side box frame on the steam introduction side and the inner wall of the steam discharge side. Ventilation paths with open tops between partition plates are removably attached, and vent holes are opened in the partition plate parts where both ends of the ventilation paths are in contact, and the top surface of the ventilation path is attached to the top plate of the fixed-side box frame. It is characterized in that it can be mounted as much as possible and that a long hole having the same width as the width of the ventilation passage is formed in the top plate portion corresponding to the back side of the fixed side frame mold.

[0006]

[Action]

 To explain the operation of the device of the present invention, the heated steam is fed into the steam chamber from the steam inlet of the fixed-side box frame, passes through the ventilation passage, and passes from the upper surface of the ventilation passage to the fixed side through the long hole of the top plate. Steam is supplied to the back side of the frame mold, but when changing the number of fixed frame molds, fix the bolts that fasten the top plate and the fixed box frame, and the top plate and the air passage. Remove the top plate by removing the bolts that are attached to the partition plate, then remove the bolts that secure the ventilation passage to the partition plate, remove the ventilation passage, and finally remove the bolt that secures the partition plate to create a partition plate. The ventilation passage can be easily removed. Therefore, with the fixed side box frame as it is, the number of ventilation passages and partition plates with vent holes that correspond to the number of fixed side frame molds that have been changed next time will be reversed on the fixed side box frame. It can be easily assembled by fastening with bolts and nuts.

【Example】

 An embodiment of the device of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional side view showing an embodiment of the device of the present invention, and FIG. Thus, in the figure, 1 is a fixed-side box frame, and the mounting wall 4 has a fixed distance from the inner wall of the fixed-side box frame 1 on the steam inlet 2 side and the inner wall of the steam outlet 3 side. It is bent along the inner wall of each. The partition plates 5 are detachably attached to the mounting walls 4 by bolts and nuts 6 to form a steam chamber 7 between the inner wall and the partition plates 5.

Reference numeral 8 denotes a ventilation passage detachably provided between the partition plates 5 with bolts and nuts 9 and the ventilation passage 8 has a gutter shape with an open upper surface. In addition, ventilation holes 10 are opened in the partition plate 5 portion to which both ends of the ventilation passage 8 are attached. The upper surface of the air passage 8 is detachably attached to the top plate 11 of the fixed-side box frame 1 with bolts and nut stoppers 12. Reference numeral 13 is a fixed-side frame die, and a long hole 14 having the same width as that of the ventilation passage 8 is formed in a top plate portion corresponding to the back side of the fixed-side frame die 13 to allow vapor to flow from the ventilation passage 8 to the fixed-side frame die 13. It is incorporated on the back side. Reference numeral 15 is an exhaust valve provided at the steam outlet 3 of the stationary side box frame 1, and 16 is a cooling water pipe. In the figure, 17 is a moving side frame type, and 18 is a moving side box frame.

[0009]

[Effect of device]

 According to the present invention, since the partition plate and the ventilation passages in the fixed side box frame are detachably attached, it is possible to replace the number of ventilation passages according to the number of the fixed side frame molds. It is a useful idea that can reduce the manufacturing cost and improve the work efficiency without the need to replace the entire fixed side box.
