Description

Glazing molding machine {Glazing molding machine}

The present invention relates to a glazing molding machine for surface treatment of a product manufactured by a method such as heat-sealing an expandable synthetic resin.

There are various molding methods such as injection method, extrusion method, vacuum method, and thermal fusion method according to the type of raw material and molding method.

The double heat welding method is a method of forming a product of a certain shape by melting raw materials by heat. The molding method by thermal fusion method is widely used for materials such as expanded synthetic resins (eg, expanded polypropylene (EPP), expanded polystyrene (EPS), etc.).

By the way, the quality of products using this thermal fusion method is influenced by the smoothness of the surface and the rigidity of the surface. Molding defects such as cracks and breakage are likely to occur.

In addition, the foamed synthetic resin has strong characteristics against vibration and noise. Therefore, in recent years, there are cases in which the foamed synthetic resin itself is used as a housing for a ventilation fan or the like. In this case, in order to reduce weight and cost, it is necessary to increase the size of the foam and manufacture it at high magnification, but there is a problem that the risk of breakage due to external force increases because the rigidity is further lowered when injection is made at high magnification. Furthermore, when the foamed synthetic resin is used as an exterior material, the foamed shape is exposed as it is, thereby impairing the aesthetic appearance.

To solve this problem, a glazing technique is used, which uses the same mold as the mold for injecting the product, and applies heat and pressure to the product to make the surface glossy. More specifically, the mold for injecting the product is first heated with a heat treatment device to fuse the raw materials to form a product, and then the injection mold is cooled to about 30 ° C to lower the temperature of the mold and product. It is manufactured by heating and glazing the surface of the product and then taking it out. In addition, since a separate mold consisting of an inner mold and an outer mold is implemented in the injection mold, the entire mold is first heated, and then only the inner mold is pressed toward the product side for secondary heating.

This glazing molding method has the advantage of enabling both product injection and glazing within the same mold, but it is complicated to implement a separate mold or implement equipment for pressing only the inner mold toward the product side. In addition, there is a disadvantage in that the product manufacturing cycle is too long because heating and cooling must be performed alternately. In addition, it is difficult to cool to an appropriate temperature between the first heating and the second heating, and the above-described molding defects such as breakage are likely to occur, and there is a problem that the product surface is not uniformly grazing.

The present invention is to solve the problems of the prior art as described above, and specifically, to provide a glazing molding machine that can improve quality by uniformly glazing the surface of a product and improve production efficiency by reducing cycle time. to be

An embodiment of the present invention provides the following glazing molding machine in order to solve the above problems.

The label unit 30 is disposed on the upper side of the lower mold in the drawing, but may be disposed and used at any position for forming a label. The label portion 30 is hardly deformed due to temperature and is formed of bakelite having low thermal conductivity, and therefore, the portion where the label portion 30 is located is not glazed. Therefore, if a sticker label is attached to this part, the label can be easily peeled off.

Hereinafter, each configuration of the flow path type as the second embodiment of the present invention will be described.

7 is a perspective view of a second embodiment of the present invention, FIG. 8 is an exploded perspective view of FIG. 7, FIG. 9 is a front view of FIG. 7, FIG. 10 is a front view of FIG. 7, and FIG. 11 is a side view of FIG. , FIG. 12 is a cross-sectional view of the second upper core in FIG. 7, and FIG. 13 is an enlarged view of parts A and B in FIG.

As shown in these figures, the second glazing mold (second glazing mold 200) of the present invention has a second upper mold 210 and a second lower mold to correspond to each configuration of the first glazing mold 100. 220 , a second upper heat transfer unit 230 , and a second lower heat transfer unit 240 .

The second upper mold 210 and the second lower mold 220 may respectively include a second upper core 213 and a second lower core 223 in which a passage is formed through.

The second upper heat transfer unit 230 may be formed of a plurality of flow channels formed inside the second upper mold 210 . The passages include an upper main inflow passage 231 through which the heat medium fluid is supplied, an upper main outflow passage 232 through which the heat medium fluid is discharged, and an upper individual passage connecting the upper main inflow passage 231 and the upper main outflow passage 232. A flow path 233 may be included. Therefore, when the heat medium fluid is supplied to the upper main inflow passage 231, the fluid is discharged through the upper main inflow passage 231, the upper individual passage 233, and the upper main outflow passage 232, and the fluid passes through the mold. During this process, the second upper mold 210 is heated to apply heat to the upper surface of the product.

Also, the second lower heat transfer part 240 may be formed of a plurality of flow channels formed inside the second lower mold 220 . The passages include a lower main inflow passage 241 through which the heat medium fluid is supplied, a lower main outflow passage 242 through which the heat medium fluid is discharged, and a lower individual passage connecting the lower main inflow passage 241 and the lower main outflow passage 242. A flow path 23 may be included. Therefore, when the heat medium fluid is supplied to the lower main inflow passage 241, the fluid is discharged through the lower main inflow passage 241, the lower individual passage 243, and the lower main outflow passage 242, and the fluid passes through the mold. During this process, the second lower mold 220 is heated to apply heat to the lower surface of the product.

When the product has a rectangular shape, the main inflow and main outflow channels are formed at opposite corners of the product in the vertical direction of the product, and the individual flow paths are formed as if branching in the horizontal direction connecting the main inflow and main outflow channels. It can be. In addition, a plurality of individual passages may be formed and matched with the main inflow passage or the main outflow passage in a one-to-many manner.

Furthermore, the upper individual passage 233 and the lower individual passage 243 may form a passage crossing portion at a point where the main inflow passage and the main outflow passage cross each other. The fluid moves through the passage crossing part, and at this time, the flow direction of the fluid is changed to pass through the individual passages. On the other hand, when the fluid is introduced from one end of the main inflow passage to the other end, the oil pressure and flow velocity of the first end are strong, so the fluid cannot flow into the individual passage and flows as it is along the main inflow passage, so there is a problem in that heat transfer is not uniform . In addition, when the fluid is said to flow out from the other end of the main outflow passage in one direction, the first end side still has a problem in that the hydraulic pressure and flow velocity are strong so that the individual passage does not smoothly flow in the direction of one end of the main outflow passage.

Therefore, in order to solve this problem, the shape of the passage crossing portion formed at one end of the main inflow passage and the main outflow passage may be modified. That is, a chamfered shape may be applied to the corner portion to smoothly flow into the individual passages and flow smoothly toward one end of the main outflow passage in consideration of the desired moving direction of the fluid.

In addition, the above-mentioned degree of deformation of the passage crossing part is greatest at one end of the main inflow passage and the main outflow passage, and the degree of deformation gradually decreases from the center part to the other end. can do. This is because there is little adverse effect by hydraulic pressure and flow velocity in the middle and later parts.

Accordingly, the cross-section of the passage crossing portion may be formed larger as the flow passage is closer to one end of the main inflow passage and the main outflow passage, and may be expanded in the direction of one end of the main inflow passage and the main outflow passage.

The above configuration is shown in detail in FIGS. 12 and 13 . Referring to this, some of the individual passages (upper individual passage 233a) disposed at one end of the main inflow passage and the main outflow passage are deformed (233c, 233d) so that the shape of the passage crossing formed at both ends is expanded. In particular, it can be seen that the larger the chamfered degree of the passage cross section is, the closer it is to one end. In addition, it can be seen that some of the individual passages 233b disposed on the other end side of the main inflow passage and the main outflow passage simply connect the main inflow passage and the main outflow passage to the individual passage without deformation of the passage crossing formed at both ends. .

Due to the above configuration, the second embodiment of the present invention can omit the complicated configuration of individual hoses compared to the first embodiment, and thus the configuration and installation are simple. In addition, the shape of the passage crossing part compensates for the influence of hydraulic pressure and flow velocity and uniformly applies heat to the mold, which has the effect of improving product quality.

Hereinafter, each configuration of the third embodiment of the cover type of the present invention will be described.

14 is a perspective view of a third embodiment of the present invention, FIG. 15 is an exploded perspective view of FIG. 14, FIG. 16 is a front view of FIG. 14, FIG. 17 is a front longitudinal sectional view of FIG. 14, and FIG. 18 is a side longitudinal sectional view of FIG. , FIG. 19 is a cross-sectional view of the third upper core in FIG. 14, and FIG. 20 is a cross-sectional view of the third lower core in FIG.

As shown in these figures, the third glazing mold 300 of the present invention is a third upper mold 310, a third lower mold 320, a third An upper heat transfer unit 330 and a third lower heat transfer unit 340 may be included.

The third upper mold 310 and the third lower mold 320 may each include a core disposed in contact with the product to form a space therein, and a cover forming a space between the core and the core.

The third upper core 314 is formed in a flat plate shape as a whole, and one surface is formed almost identically to contact the upper surface of the product, which is a general matter. The other surface of the third upper core 314 is formed in a shape corresponding to one surface of the third upper core 314 .

The meaning of "corresponding" here can be grasped from the illustration of FIG. 17 and the like. In addition, the shape is not completely the same, but the mold is formed to a certain thickness as a whole, and considering the thickness of the mold, even if the shape of a part formed in detail is simplified, it can be seen that the overall shape is similar and the size is the same. The corresponding meaning in the present application specification is as described above.

In addition, the upper cover 313 is coupled to the third upper core 314 so that its outer edge is in contact with each other, and the inner side is formed to be spaced apart from each other. Accordingly, a space may be formed between the upper cover 313 and the third upper core 314 . And, in order to maintain the thickness of the space constant, the other surface of the third upper core 314 and one surface of the upper cover 313 facing this may be formed in a shape corresponding to each other. Accordingly, heat applied to the space can be uniformly distributed, and product quality can be improved.

The third lower core 324 and the lower cover 323 may also be formed similarly to the third upper core 314 and the upper cover 313 .

In addition, the third upper heat transfer part 330 is formed by penetrating the upper space 333 formed between the upper cover 313 and the third upper core 314, the upper cover 313, or the third upper core 314. and may include a flow path communicating with the upper space 333. The passage includes an upper main inlet 331 through which the heat medium fluid flows in, an upper main inlet passage guide 332 connecting the upper main inlet 331 and the upper space 333, and an upper main through which the heat medium fluid is discharged. An upper outlet flow guide 335 connecting the outlet 334 , the upper space 333 and the upper main outlet 334 may be included.

Like the third upper heat transfer unit 330, the third lower heat transfer unit 340 also includes a lower main inlet 341, a lower inlet flow guide 342, a lower space 343, a lower main outlet 344, and a lower An outflow flow guide 345 may be included.

On the other hand, the flow guide may be formed to be branched from the main inlet or main outlet and connected to the space between the cover and the core. The flow guide is configured to deliver fluid evenly to the space, and branch portions 332a, 335a, 342a, and 345a branching from the main inlet or main outlet, and connected in a straight line toward the space at the end of the branch Straight portions 332b, 335b, 342b, and 345b may be included. Therefore, the fluid is evenly spread by the branch portion, and the fluid can flow along the longitudinal direction of the product without being concentrated to the corner in the space by the straight portion.

By the above configuration, when the heat medium fluid is supplied to the upper main inlet 331, the upper main inlet 331, the upper inlet flow guide (a, b) 332, the upper space 333, and the upper outlet The fluid is discharged through the flow guide 335 and the upper main outlet 334, and while the fluid passes through the mold, the third upper mold 310 is heated to apply heat to the upper surface of the product.

In addition, when the heat medium fluid is supplied to the lower main inlet 341, the lower main inlet 341, the lower inlet flow guide 342, the lower space 343, the lower outlet flow guide 345, the lower main outlet The fluid is discharged through 344, and while the fluid passes through the mold, the third lower mold 320 is heated to apply heat to the lower surface of the product.

The cover type has an effect of superior product quality even when compared to the hose type or the euro type. In the case of a hose type or flow path type, it is difficult to configure a flow path in a shape corresponding to the shape of the product, and only a straight flow path is applied in reality due to technical difficulties and cost problems. However, since the cover type can form a fluid space in the same way as forming the outer shape of a conventional mold, it is easy to implement more delicately along the portion to be heated.

In this specification, each embodiment has been separately described, but embodiments that can be derived by arbitrarily combining some configurations of each embodiment also fall within the scope of the present invention.

The above description is only illustrative of the technical idea of the present invention, and those skilled in the art can make various modifications and variations without departing from the essential characteristics of the present invention. The protection scope of should be interpreted by the claims below, and all technical ideas within the equivalent range should be construed as being included in the scope of the present invention.
