TECHNICAL FIELD

[0001] The utility model relates to cake mould field especially, a kind of spherical cake baking mould. BACKGROUND

[0002] With the growth of economy and the development of society, people's living standard quality is higher and higher, and the requirement of baked food is also higher and higher. Today's cake not only satisfies the demand of different groups of people in flavor, but also has great changes in appearance, and spherical cake appears, and in order to produce spherical cake, spherical cake baking mould appears.

[0003] The Chinese patent with application No.201621107713.9 discloses a spherical cake baking mould, which comprises a cake baking mould body, the cake baking mould body is composed of an upper hemisphere and a lower hemisphere, the upper hemisphere and the lower hemisphere are connected with each other to form a spherical structure, the lower edge of the upper hemisphere is provided with two upper fixing ears, the upper edge of the lower hemisphere is provided with two lower fixing ears, the upper fixing ears and the lower fixing ears are provided with mutually matched fixing holes, and the upper fixing ears and the lower fixing ears are fixed by screws; a plurality of uniformly distributed exhaust holes are formed in the upper hemisphere.

[0004] When the spherical cake baking mould is assembled, the fixing holes in the upper fixing ears and the lower fixing ears need to be aligned first, and then the upper hemisphere and the lower hemisphere are connected or disassembled by screws, which is complicated to operate and needs additional tools such as screwdrivers for assistance. In addition, since the screws are small, they are easy to lose during assembly, disassembly or storage. UTILITY MODEL CONTENTS

[0005] The utility model provides a spherical cake baking mould which is not easy to lose parts, is convenient to assemble and disassemble, and does not need additional tools for assistance, in view of the shortcomings that the spherical cake mould in the prior art is complicated to assemble, needs additional tools for assistance, and screws are easy to lose.

[0006] In order to solve the above technical problems, the utility model solves the problems by the following technical solutions:

[0007] A spherical cake baking mould, which comprises an upper mould and a lower mould that can be closed to each other to form a spherical baking space or separated from each other, at least one exhaust hole is arranged on the side of the upper mould away from the lower mould to communicate the spherical baking space with the outside, the upper mould and the lower mould are hinged, and a sealing ring is arranged on the side of the upper mould close to the lower mould to seal and fit the lower mould when the upper mould and the lower mould are closed to seal the closed part of the upper mould and the lower mould, a sealing cavity is arranged in the upper mould, a through groove is arranged on the sealing ring to communicate the sealing cavity with the outside and be sealed by the lower mould when the upper mould and the lower mould are closed, and a negative pressure control assembly is arranged in the upper mould to form negative pressure in the sealing cavity to enable the upper mould and the lower mould to be negatively adsorbed or the negative adsorption to be released.

[0008] The above scheme only needs to rotate the upper mold to close the lower mold to form a spherical baking space, at this time the sealing ring seals the closed part of the upper and lower molds, and the through groove is blocked by the lower mold, which simplifies the alignment operation. Then, the negative pressure control assembly controls the formation of negative pressure in the sealing cavity and the through groove, so that the upper mold and the lower mold are negatively adsorbed together to limit their mutual separation; when disassembling, the negative pressure control assembly controls the normal pressure in the sealing cavity and the through groove to be restored, and the upper mold is reversely rotated, without the need to repeatedly tighten or loosen the screws, and the operation is convenient. The sealing ring and the negative pressure control assembly are arranged on the upper mold, and are not easy to lose, and do not need additional tools for assistance. In addition, whether the negative pressure adsorption is effective or not can also identify whether the closed part of the upper mold and the lower mold is sealed. If the upper mold and the lower mold are negatively adsorbed together, the sealing is complete, and the cake liquid can be prevented from overflowing during preparation; if the sealing is not complete, air will enter the sealing cavity through the gap between the upper mold and the lower mold and the through groove, so that the upper mold and the lower mold cannot be negatively adsorbed. Therefore, if the upper mold and the lower mold are not adsorbed together, the sealing is not complete, and the sealing ring needs to be checked or replaced.

[0009] As preferred, the negative pressure control assembly comprises a sliding groove arranged in the upper mold and communicating with the sealing cavity, and a sealing block movably arranged in the sliding groove and away from the sealing cavity to form negative pressure in the sealing cavity or close to the sealing cavity to restore normal pressure in the sealing cavity, movement of the sealing block being controlled by a control structure.

[0010] The above scheme drives the sealing block to move away from the sealing cavity to exhaust air in the sealing cavity to the sliding groove to form negative pressure in the sealing cavity; conversely, the control structure drives the sealing block to move close to the sealing cavity to push air in the sliding groove into the sealing cavity to restore normal pressure in the sealing cavity.

[0011] As preferred, the control structure comprises a driving rod protruding through the upper mold at one end of the upper end surface of the sealing block and located outside the upper mold, an avoiding groove arranged on the upper mold for movement of the driving rod, and a limiting structure arranged between the upper mold and the driving rod to limit the driving rod from returning when the driving rod moves away from the sealing cavity to a preset stroke.

[0012] With the above scheme, moving the driving rod away from the sealing cavity can drive the sealing block away from the sealing cavity, and when the driving rod moves away from the sealing cavity to the preset stroke, the limiting structure limits the backtracking, i.e., limits the backtracking of the sealing block, so that the negative pressure state in the sealing cavity is maintained. Conversely, the limiting structure is unlocked, and moving the driving rod close to the sealing cavity can drive the sealing block close to the sealing cavity. In addition, the negative pressure formed in the sealing cavity will decrease to a certain extent during high-temperature baking, so when the driving rod and the sealing block move away from the sealing cavity to the preset stroke, the negative pressure value generated in the sealing cavity after the high-temperature decrease is still greater than the pressure value in the spherical baking space, which can ensure that the upper mold and the lower mold do not separate from each other. And because of the existence of the exhaust hole, during the expansion of the cake liquid in the spherical baking space, the excess air will be quickly discharged to the outside through the exhaust hole, so the pressure in the spherical baking space is relatively small compared with the normal pressure, and therefore the negative pressure required to limit the separation of the upper mold and the lower mold will not be too large.

[0013] Preferably, the limiting structure includes a limiting block elastically retracted on the side wall parallel to the moving direction of the driving rod, which elastically retracts until the driving rod moves to the preset stroke and resets and limits the reverse movement of the driving rod.

[0014] With the above scheme, the driving rod is elastically retracted after being extruded and sliding with the limiting block during the movement away from the sealing cavity, and after the driving rod passes the limiting block, the extrusion force from the driving rod on the limiting block disappears, and the limiting block is elastically extended to reset and limit the reverse backtracking of the driving rod.

[0015] Preferably, a retractable groove is recessed on the side wall of the avoiding groove for guiding the extension and retraction of the limiting block, a first spring is arranged between the retractable groove and the limiting block to drive the limiting block to partially extend out of the retractable groove in a normal state, and an extrusion slope is arranged on the side of the limiting block close to the sealing cavity to drive the limiting block to elastically retract when being extruded by the driving rod.

[0016] With the above scheme, the arrangement of the extrusion slope ensures that the driving rod can drive the limiting block to elastically retract when being extruded, and at this time the first spring is deformed to generate elastic force; after the driving rod passes the limiting block, the reset elastic force of the first spring drives the limiting block to partially extend to limit the backtracking of the driving rod.

[0017] Preferably, a pull rod is arranged on the side of the limiting block close to the first spring and extends in the retraction direction of the limiting block, one end of the pull rod passes through the upper mold and is located outside the upper mold.

[0018] With the above scheme, when the limiting block is unlocked, the limiting block needs to be elastically retracted by artificial driving, and the pull rod is arranged, so that the limiting block can be elastically retracted by pulling the pull rod in the retraction direction of the limiting block, which is more convenient to apply force and easier to operate.

[0019] Preferably, a second spring is arranged between the sealing block and the sliding groove to drive the sealing block to move close to the sealing cavity to the initial position when the limiting block is released.

[0020] With the above scheme, when the sealing block moves away from the sealing cavity, the second spring is deformed to generate a restoring force, and once the resistance from the limiting block on the driving rod disappears, the sealing block can be driven to move close to the sealing cavity to the initial position, ensuring that the normal pressure is restored in the sealing cavity.

[0021] Preferably, the through grooves are uniformly and axially spaced.

[0022] With the above scheme, multiple through grooves are arranged to ensure the negative pressure adsorption strength while making the force between the upper mold and the lower mold more uniform.

[0023] The above technical scheme has the following remarkable technical effects: only two simple operations of rotating the upper mold and pulling the driving rod are needed to assemble the spherical baking space. Conversely, only the pull rod needs to be pulled and the upper mold needs to be rotated in the opposite direction to disassemble, which is convenient to assemble and disassemble, and no additional tools are needed. The parts are assembled on the upper mold and are not easy to lose. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0033] The utility model will be described in further detail below in combination with the drawings and examples.

[0034] Embodiment

[0035] A spherical cake baking mold, referring to Figures 1 to 8 , comprises a hinged upper mold 1 and lower mold 2. Both can be closed to form a spherical baking space 3 by rotating close to each other; both can be opened by rotating away from each other to demold the spherical cake. The inner walls of the upper mold 1 and the lower mold 2 are coated with a non-stick coating, which facilitates demolding. The composition of the non-stick coating and the coating method of the non-stick coating are both prior art, and the present scheme does not improve them, so they are not shown in the drawings and will not be described here.

[0036] The side of the upper mold 1 away from the lower mold 2 is provided with an exhaust hole 4 communicating the spherical baking space 3 with the outside. When the cake liquid expands and forms in the spherical baking space 3, the excess gas in the spherical baking space 3 is discharged to the outside through the exhaust hole 4, avoiding excessive pressure in the spherical baking space 3.

[0037] The side of the upper mold 1 close to the lower mold 2 is concentrically recessed with an accommodating ring groove 18, and a sealing ring 5 is fixedly and sealingly embedded in the accommodating ring groove 18. When the upper mold 1 and the lower mold 2 are closed, the side of the sealing ring 5 away from the bottom of the accommodating ring groove 18 is sealingly attached to the side of the lower mold 2 close to the upper mold 1, ensuring that the upper mold 1 and the lower mold 2 are sealingly closed to prevent the cake liquid from overflowing from there. In this embodiment, the side of the lower mold 2 close to the upper mold 1 is concentrically fixed with a sealing layer sealingly attached to the sealing ring 5, further ensuring that the two are sealingly attached. The sealing layer is prior art and is not shown in the drawings, so it will not be described here.

[0038] The bottom of the accommodating ring groove 18 is concentrically recessed with a sealing cavity 6, and the opening of the sealing cavity 6 close to the accommodating ring groove 18 is completely sealed by the sealing ring 5. The sealing ring 5 is provided with a through groove 7 along the axial direction of the sealing ring 5, which communicates the sealing cavity 6 with the outside, and the through groove 7 can be sealingly blocked by the side of the lower mold 2 close to the upper mold 1 when the upper mold 1 and the lower mold 2 are sealingly closed. The through groove 7 is uniformly and spacedly provided with 12 around the sealing ring 5.

[0039] The upper die 1 is provided with a sliding groove 8 communicated with the sealing cavity 6, and a sealing block 9 is movably arranged in the sliding groove 8 and can move close to or away from the sealing cavity 6. The upper end surface of the sealing block 9 away from the lower die 2 is provided with a driving rod 10 protruding away from the lower die 2, and the driving rod 10 is arranged on the upper end surface of the sealing block 9 away from the sealing cavity 6. One end of the driving rod 10 away from the sealing block 9 penetrates through the upper die 1 and is located outside the upper die 1. The upper die 1 is provided with an avoiding groove 11 for the reciprocating movement of the driving rod 10.

[0040] During the sealing movement of the sealing block 9, the chamber formed between the side of the sliding groove 8 away from the sealing cavity 6 and the side of the sealing block 9 away from the sealing cavity 6 is always communicated with the outside through the avoiding groove 11, so as to ensure that the air pressure on the side of the sealing block 9 away from the sealing cavity 6 is normal pressure, and facilitate the movement of the sealing block 9.

[0041] The second spring 17 is arranged between the sliding groove 8 and the sealing block 9, and the two ends of the second spring 17 are fixedly connected or abutted with the side of the sliding groove 8 away from the sealing cavity 6 and the side of the sealing block 9 away from the sealing cavity 6, respectively. When the second spring 17 is in the initial state, the sealing block 9 is located at the initial position, and the initial position is the position where the driving rod 10 abuts against the side wall of the avoiding groove 11 close to the sealing cavity 6. At this time, the sealing cavity 6 is in normal pressure.

[0042] The avoiding groove 11 is provided with an expansion groove 14 on the side wall parallel to the moving direction of the driving rod 10, and a limiting block 12 is telescopically arranged in the expansion groove 14. The first spring 15 is arranged between the expansion groove 14 and the limiting block 12, and the two ends of the first spring 15 are fixedly connected or abutted with the bottom of the expansion groove 14 and the side of the limiting block 12 close to the bottom of the expansion groove 14, respectively. When the first spring 15 is in the initial state, the limiting block 12 is in the state of partially protruding. The side of the limiting block 12 close to the sealing cavity 6 is provided with an extrusion inclined surface 13, which is inclined away from the sealing cavity 6 from one end close to the expansion groove 14 to the other end away from the expansion groove 14.

[0043] The side of the limiting block 12 close to the first spring 15 is provided with a pull rod 16 extending in the retracting direction of the limiting block 12, and one end of the pull rod 16 away from the limiting block 12 penetrates through the upper die 1 and is located outside the upper die 1.

[0044] When baking is needed, pour the cake liquid into the lower mold 2, rotate the upper mold 1 to close the lower mold 2 to form a spherical baking space 3, at this time the sealing ring 5 seals the closed part of the two and the through slot 7 is blocked by the lower mold 2. Then only need to pull the drive rod 10 away from the sealing cavity 6, the drive rod 10 and the extrusion slope 13 extrude and slip, and then drive the limiting block 12 to retract elastically into the telescopic slot 14 until the drive rod 10 passes the limiting block 12, the extrusion force from the drive rod 10 on the limiting block 12 disappears, the limiting block 12 partially extends under the elastic force of the first spring 15 to limit the drive rod 10 from retracting, at this time the drive rod 10 moves to the preset position, the preset position is the position of the drive rod 10 moving away from the sealing cavity 6 to pass the limiting block 12, that is, the drive rod 10 is located between the side of the avoiding slot 11 away from the sealing cavity 6 and the side of the limiting block 12 away from the sealing cavity 6. In the above process, the sealing block 9 moves away from the sealing cavity 6 with the drive rod 10 to form a negative pressure in the sealing cavity 6 and maintain the negative pressure state, and the negative pressure adsorption between the upper mold 1 and the lower mold 2 limits the two from separating.

[0045] When the cake is demolded, pull the pull rod 16 to drive the limiting block 12 to retract, the resistance from the limiting block 12 on the drive rod 10 disappears, under the action of the second spring 17, the sealing block 9 moves close to the sealing cavity 6 and resets to the initial position, the atmospheric pressure in the sealing cavity 6 is restored, and the spherical cake can be demolded by rotating the upper mold 1 in the opposite direction.

[0046] The above is only the preferred embodiment of the present application, the protection scope of the present application is not limited to the above embodiment, any technical solution belonging to the idea of the present application is within the protection scope of the present application. It should be noted that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
