Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of foaming forming, and particularly relates to a foaming furnace device with a shaping function. BACKGROUND

[0002] In the foaming forming process or foaming polymer material, a honeycomb or porous structure is formed through the addition and reaction of a physical foaming agent or a chemical foaming agent. The basic steps of foaming forming are the formation of bubble nuclei, the growth or expansion of bubble nuclei, and the stabilization of bubble nuclei. Under given temperature and pressure conditions, the solubility of gas decreases to reach saturation, so that the excess gas is discharged and bubbles are formed, thereby realizing nucleation.

[0003] For example, a SAN foaming plate is a lightweight porous material made of styrene-acrylonitrile copolymer (SAN) as a base material through a foaming process. The SAN foaming plate is usually made through a mold pressing foaming process. During mold pressing foaming, a special mold limits the shape of foaming forming, so that the SAN foaming plate after foaming is regular and has no burrs.

[0004] However, the foaming plate and the inner wall of the mold are in a tightly closed state after forming. When demolding, the friction between the foaming plate and the mold is large, which is easy to cause damage to the outer peripheral surface of the foaming plate. SUMMARY

[0053] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0054] Please refer to Figures 1 to 8 A foaming furnace device with a shaping function is described. The foaming furnace device with a shaping function comprises a machine body 10 with a shaping cavity 101, a mold 20, an adjusting member, a sealing unit 30 and a lifting unit 40; the mold 20 is arranged in the shaping cavity 101, the mold 20 is provided with an annular expansion cavity 201, and the expansion cavity 201 is filled with an extruded material; the adjusting member is in communication with the expansion cavity 201 and is used to fill the expansion cavity 201 with the extruded material or empty the expansion cavity 201; the sealing unit 30 comprises a machine cover 301 above the shaping cavity 101 and a cover plate 302 arranged on the bottom wall of the machine cover 301, the machine cover 301 is used to seal the shaping cavity 101, and the cover plate 302 is used to seal the opening of the mold 20; the lifting unit 40 is connected to the machine cover 301 and is used to drive the machine cover 301 to move in the up-down direction.

[0055] Optionally, the extruded material is water, and the adjusting member is a water pump and an air pump, the water pump is used to complete water injection and water extraction into the expansion cavity 201, and the adjusting member is in communication with a water tank and an air tank.

[0056] Before shaping, the air pump is used to pump the air in the air tank into the expansion cavity 201, so that the air pressure in the expansion cavity 201 is restored to atmospheric pressure, and then the water pump is used to pump the water in the water tank into the expansion cavity 201; when demolding, the water pump is used to first extract the water in the expansion cavity 201, and then the air pump is used to extract the expansion cavity 201 to a negative pressure state.

[0057] Optionally, the extruded material is a heat-stable polymer (such as a silicon-based gel), and the adjusting member is a pressure pump, and the adjusting member is in communication with a storage tank.

[0058] Before foaming and shaping, the adjusting member is used to pump the extruded material from the storage tank into the expansion cavity 201, and when demolding, the adjusting member is used to pump the extruded material from the expansion cavity 201 into the storage tank.

[0059] Compared with the prior art, the annular expansion cavity 201 inside the mold 20 is arranged around the forming area, and the cross-sectional shape thereof matches the profile of the target foamed part. After the foaming material is injected into the mold 20, the adjusting part injects the extrusion material into the expansion cavity 201, so that the expansion cavity 201 is completely filled. During the heating stage, when the foaming material is heated and expanded, the extrusion material in the expansion cavity 201 exerts uniform radial constraint force on the forming area, so as to force the inner wall of the mold 20 to tightly fit with the foaming material; after the foaming and shaping are completed, the adjusting part is switched to the negative pressure mode, so as to draw back the extrusion material, so that the expansion cavity 201 is empty in volume, thereby forming a demolding gap between the mold 20 and the formed part, reducing the friction between the formed part and the mold 20, and reducing the damage to the outer peripheral surface of the formed part.

[0061] The clamping unit 50 comprises a moving seat 501 and a positioning part, the moving seat 501 is provided with a sliding groove 5011 which is slidably matched with the annular guide rail 103, and the sliding groove 5011 is provided with a abutting part 60 which is telescopic in the up-down direction; and the positioning part is arranged on the moving seat 501 and is telescopic in the direction away from or close to the outer wall of the mold 20.

By adjusting the position of the moving seat 501, the abutting position of the positioning part after being extended and the outer wall of the mold 20 is the best stress point, so as to improve the stability of the mold 20 during the foaming and forming process; and the position of the positioning part can be adjusted at will, and can also be matched with molds 20 of different shapes, so as to improve the application range of the device.

[0064] In some embodiments, the abutting part 60 is a telescopic oil cylinder, a hydraulic cylinder or an electric cylinder.

[0065] In some embodiments, referring to Figure 4The abutting member 60 comprises a first telescopic device 601 and an abutting base 602. The first telescopic device 601 is telescopic in the up-down direction, and a fixed end of the first telescopic device 601 is fixedly connected to the inner wall of the sliding groove 5011. The abutting base 602 is fixedly connected to a movable end of the first telescopic device 601.

[0066] Specifically, the first telescopic device 601 is a telescopic oil cylinder, a hydraulic cylinder or an electric cylinder.

[0067] The first telescopic device 601 is extended to drive the abutting base 602 to move towards the direction close to the annular guide rail 103, so as to fix the relative position of the moving base 501 and the annular guide rail 103 by friction. It should be noted that the abutting base 602 has a concave surface matched with the annular guide rail 103, which increases the contact area with the annular guide rail 103, thereby improving the static stability of the moving base 501.

[0068] In some embodiments, referring to Figure 4 The abutting base 602 is provided with a receiving cavity 6021 on one side thereof facing the annular guide rail, and the receiving cavity 6021 is provided with a first telescopic member 6022.

[0070] The first telescopic member 6022 is extended to drive the lifting plate 6023 to move towards the direction close to the annular guide rail 103, so that the universal wheel 6024 contacts the annular guide rail 103. When the moving base 501 slides, the universal wheel 6024 rolls to reduce friction, thereby prolonging the service life of the annular guide rail 103. The first telescopic member 6022 is retracted to drive the lifting plate 6023 to move away from the reversing guide rail, so that the universal wheel 6024 is separated from the annular guide rail 103. Then, the abutting member 60 is moved towards the direction close to the annular guide rail 103 until the abutting member 60 is in abutment with the annular guide rail 103.

[0071] In some embodiments, referring to Figure 5 The positioning member comprises a second telescopic device 502 and a limiting rod 503. The second telescopic device 502 is telescopic in the direction close to or away from the mold 20, and a fixed end of the second telescopic device 502 is fixedly connected to the moving base 501. The limiting rod 503 is connected to a movable end of the second telescopic device 502.

[0072] Specifically, the second telescopic member 303 is a telescopic oil cylinder, a hydraulic cylinder or an electric cylinder.

[0073] The second telescopic device 502 pushes the limiting rod 503 to abut against the outer wall of the mold 20, and fixes the mold 20 through radial pressure, so that the mold 20 is clamped in the radial direction to avoid moving, and the position of the mold 20 is ensured. The telescopic structure is suitable for molds 20 of different specifications and molds 20 of different shapes, and the application range of the device is improved.

[0075] Specifically, the driving member 506 is a motor, and a driving gear 5061 is fixedly connected to the output shaft of the driving member 506, and the outer periphery of the rotating ring 505 is provided with gear teeth in meshing connection with the driving gear 5061.

[0076] Specifically, the end of the limiting rod 503 is hingedly connected with a mounting block 5031, and the mounting block 5031 is screwed with the mounting seat 504.

[0077] The driving member 506 drives the driving gear 5061 to rotate, the driving gear 5061 drives the driven gear to rotate, and the driven gear drives the rotating ring 505 to rotate. In the rotating process, the rotating ring 505 drives the limiting rod 503 to rotate around the hinge shaft through the angle adjusting assembly, so as to adjust the angle between the limiting rod 503 and the mounting seat 504, thereby adjusting the clamping angle to adapt to the profile of the mold 20 and improving the clamping stability of the mold 20.

[0078] The limiting rod 503 is detachably connected, and limiting rods 503 of different lengths can be replaced to abut against the outer wall of the mold 20, so as to be suitable for molds 20 of more shapes. The second telescopic device 502 can adjust the extension length of the limiting rod 503 in a small range, and when the telescopic length of the second telescopic device 502 cannot meet the requirement, the limiting rod 503 can be replaced to adapt to the length reaching the outer wall of the mold 20.

The elastic rod 508 is fixedly connected between the transverse rod 507 and the mounting seat 504 and has a pre-tightening force for moving the transverse rod 507 away from the limiting rod 503. The pressing block 509 is fixedly connected to the inner wall of the through hole 5051. The pressure receiving block 510 is fixedly connected to the outer wall of the transverse rod 507 and is provided with an inclined surface that abuts against the pressing block 509.

At this time, the other pressing block 509 moves away from the pressure receiving block 510, and the elastic rod 508 releases the elastic force to make the transverse rod 507 move radially away from the limiting rod 503, thereby changing the angle between the limiting rod 503 and the mounting seat 504.

[0084] In some embodiments, referring to Figure 2 , the outer wall of the mold 20 is provided with a limiting hole 202 adapted to the insertion of the limiting rod 503.

[0085] The limiting rod 503 is inserted into the limiting hole 202 of the outer wall of the mold 20 to form a hard constraint in the form of insertion, thereby completely limiting the position of the mold 20 and further improving the clamping stability of the mold 20.

[0086] In some embodiments, referring to Figure 7 , the sealing unit 30 further comprises a second telescopic member 303 arranged between the cover 301 and the cover plate 302 and telescoping in the up-down direction.

[0088] In some embodiments, referring to Figure 8The lifting unit 40 is provided with two, two lifting units 40 are oppositely arranged on the two sides of the cover 301, the lifting unit 40 comprises a screw rod 401 and a power element 402; the axis direction of the screw rod 401 is parallel to the up-down direction, the screw rod 401 is rotationally connected to the machine body 10, and the screw rod 401 is also screwed with the cover 301; the power element 402 is drivingly connected with the screw rod 401, and is used for driving the screw rod 401 to rotate around the up-down direction as the rotation axis.

[0089] Specifically, the power element 402 is an electric motor.

[0090] The power element 402 drives the screw rods 401 on the two sides to synchronously rotate, and drives the cover 301 to stably lift along the screw pair. The double-screw rod 401 structure eliminates the risk of unbalanced load of single-point driving, and ensures the horizontal movement of the cover 301; the self-locking characteristic of the screw transmission prevents accidental sliding, and the safety is high.
