Description

Technical Field

[0001] The invention relates to a shoe-making device, in particular to a two-color rain boot machine. Background Art

[0002] The rain boot machine is a device used to produce and process rain boots, generally including a transmission mechanism, a rain boot mold arranged on the transmission mechanism, and a primary injection molding mechanism, a mold switching mechanism and a secondary injection molding mechanism arranged along the transmission direction of the transmission mechanism. The existing rain boot mold includes a fixed seat, a core mold arranged on the fixed seat, a left lower mold and a right lower mold movably arranged on the fixed seat, a boot shaft forming cover plate rotatably arranged on the left lower mold, and a sole forming cover plate rotatably arranged on the right lower mold.

[0003] The production process is to first open the lower left mold and the lower right mold, set the rain boot lining on the core mold, and then surround the lower left mold, the lower right mold and the boot shaft forming cover plate around the core mold to form a mold cavity; and under the action of the transmission mechanism, it is transmitted to the primary injection molding mechanism to process the boot shaft. Then it is transmitted to the mold switching mechanism, which is used to separate the boot shaft forming cover plate and set the sole forming cover plate on the lower left mold and the upper right mold to achieve secondary mold closing, and then it is transmitted to the secondary injection molding mechanism to process the sole, so as to complete the processing of the rain boots.

[0004] The existing mold switching mechanism is a structure of multiple cylinders and top blocks. The cylinder first flips the boot shaft forming cover plate to the mold closing position, and then flips the sole forming cover plate to the mold closing position, so as to complete the switching operation between the two cover plates. The above operation makes the two cover plates freely flip after being stressed during the switching process, which causes the cover plates to generate a lot of noise during the switching process, thereby affecting the physical and mental health of the staff. In addition, the rain boot molds are very likely to deform and wear each other after colliding with each other, which will also affect the processing quality of the product to a certain extent. Based on the above problems, the present invention was conceived. Summary of the invention

[0005] The purpose of the present invention is to provide a two-color rain boot machine, which can reduce the noise generated during the processing and reduce the wear of the rain boot mold, so as to improve the processing quality of the product and improve the working environment of the staff.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a two-color rain boot machine, including a transmission mechanism, a rain boot mold arranged on the transmission mechanism, the rain boot mold including a fixed seat, a core mold arranged on the fixed seat, a lower left mold and a lower right mold rotatably arranged on the fixed seat and reciprocating toward the core mold, a boot shaft forming cover plate rotatably arranged on the lower left mold, and a sole forming cover plate rotatably arranged on the lower right mold, when the lower left mold and the lower right mold are in a mold closing state, a mold closing position is formed above the lower left mold and the lower right mold, and the boot shaft forming cover plate and the sole forming cover plate can be rotated to the mold closing position, a locking component is arranged between the lower left mold and the lower right mold, and also includes a transmission component, which is arranged on the rain boot mold. Used to realize power transmission; the left linkage component is configured to form a linkage between the transmission component and the boot shaft forming cover plate; the right linkage component is configured to form a linkage between the transmission component and the sole forming cover plate; the transmission component has a separation state and a combination state, when the transmission component is in the combination state, the boot shaft forming cover plate and the sole forming cover plate are driven to move through the left linkage component and the right linkage component, when the transmission component is in the separation state, the transmission component does not interfere with the free movement between the boot shaft forming cover plate and the sole forming cover plate; the switching component is configured to control the transmission component to switch between the separation state and the combination state; the power component is configured to provide power to the transmission component.

[0007] By adopting the above technical solution, the locking assembly is unlocked to open the lower left mold and the lower right mold, and then the rain boot lining is installed on the core mold, and then the lower left mold and the lower right mold are closed and locked by the set locking assembly. Then, the transmission assembly is controlled to switch to the separation state through the set switching assembly, so that the existing transmission assembly will not interfere with the free movement of the boot shaft forming cover plate and the sole forming cover plate, and the boot shaft forming cover plate can be manually rotated to the mold closing position to cooperate with the lower left mold and the lower right mold to form a mold cavity for processing the boot shaft, and it will not interfere with the position state of the sole forming cover plate. After the processing of the boot shaft is completed, the transmission assembly is controlled to switch to the joint state through the switching assembly, and then the transmission assembly is driven by the power assembly through the left linkage assembly and the right linkage assembly to drive the boot shaft forming cover plate and the sole forming cover plate to rotate. The specific method is to first drive the boot shaft forming cover plate to leave the mold closing position, and then rotate the sole forming cover plate to the mold closing position to cooperate with the lower left mold and the lower right mold to form a mold cavity for secondary processing of the sole on the basis of the boot shaft. The above-mentioned linkage operation mode ensures that the two covers do not generate noise during the switching and flipping process, and avoids wear caused by collision between them, thereby improving the processing quality of the product and the working environment of the staff.

[0008] It is further configured as follows: the transmission assembly includes a left transmission shaft rotatably disposed in the left lower mold and moving with the left lower mold, a right transmission shaft rotatably disposed in the right lower mold and moving with the right lower mold, and an internal permanent magnet coupling connecting the left transmission shaft and the right transmission shaft; when the left lower mold and the right lower mold are in a mold closing state, the left transmission shaft and the right transmission shaft are coaxially disposed, the inner rotor of the internal permanent magnet coupling is fixed to the left transmission shaft, and the outer rotor is fixed to the right transmission shaft.

[0009] By adopting the above technical solution, the characteristic of the internal permanent magnet coupling without direct mechanical connection enables the left transmission shaft and the right transmission shaft to realize mechanical transmission without interfering with the normal opening and closing operations of the left lower mold and the right lower mold, thereby meeting the use requirements of the working condition and realizing power transmission.

[0010] The further configuration is as follows: the left transmission shaft slides with the left lower mold along its axis and drives the inner rotor to move synchronously, the end of the left transmission shaft opposite to the inner rotor passes through the left lower mold and extends to the outside, and the switching assembly includes a separation spring that drives the inner rotor to move opposite to the outer rotor side and a clamping cylinder that is arranged on the transmission direction side of the transmission mechanism and is used to drive the left transmission shaft to drive the inner rotor to move toward the outer rotor side.

[0011] By adopting the above technical solution, the separation spring drives the inner rotor to move in the opposite direction to the outer rotor, so that the two structures will not cause structural interference during the closing process of the left lower mold and the right lower mold. When the rain boot mold is transmitted to the position corresponding to the abutting cylinder, the left transmission shaft is driven by the abutting cylinder to drive the inner rotor to move toward the outer rotor, so that the internal permanent magnetic coupling can form a linkage between the left transmission shaft and the right transmission shaft. Through the above setting structure, only one set of switching components is required to realize the control of the transmission components in each rain boot mold, which is lower in cost.

[0012] It is further configured as follows: the boot shaft forming cover plate is rotatably connected to the left lower mold through a left rotating shaft and the boot shaft forming cover plate rotates with the left rotating shaft, the left linkage assembly includes a left first-stage linkage shaft, a left second-stage linkage shaft, a left first-stage gear structure connecting the left transmission shaft and the left first-stage linkage shaft, a left second-stage gear structure connecting the left first-stage linkage shaft and the left second-stage linkage shaft, and a left third-stage gear structure connecting the left second-stage linkage shaft and the left rotating shaft, the left first-stage gear structure includes an active bevel gear that rotates with the left transmission shaft and slides along the axis of the left transmission shaft, and a driven bevel gear that is arranged on the left first-stage linkage shaft and meshes with the active bevel gear, and the left lower mold cooperates with the driven bevel gear to limit the active bevel gear to always mesh with the driven bevel gear.

[0013] By adopting the above technical solution, the above structure is used to transmit the power on the left transmission shaft to the left rotating shaft to drive the boot shaft forming cover plate to rotate, and by arranging the active bevel gear and the left transmission shaft in an axial sliding circumferential linkage manner, the moving left transmission shaft will not interfere with the normal transmission of the left first-stage gear structure, thereby ensuring the stable movement of the structure without causing interference.

[0014] It is further configured as follows: the sole forming cover plate is rotatably connected to the right lower mold via a right rotating shaft and the sole forming cover plate rotates with the right rotating shaft, and the right linkage assembly includes a right primary linkage shaft rotatably arranged in the right lower mold, a right secondary linkage shaft, a right primary gear structure connecting the right transmission shaft and the right primary linkage shaft, a right secondary gear structure connecting the right primary linkage shaft and the right secondary linkage shaft, and a right third gear structure connecting the right secondary linkage shaft and the right rotating shaft.

[0015] By adopting the above technical solution, the above structure is used to transmit the power on the right transmission shaft to the right rotating shaft to drive the sole forming cover plate to rotate.

[0016] It is further configured as follows: one end of the right transmission shaft opposite to the outer rotor passes through the right lower mold and extends to the outside, and the power component includes a power motor arranged on one side of the transmission direction of the transmission mechanism and reciprocating toward the transmission mechanism, a driving cylinder driving the power motor to move, and an external permanent magnet coupling connecting the output shaft of the power motor and the right transmission shaft.

[0017] By adopting the above technical solution, when the rain boots mold is transmitted to the position corresponding to the power motor, the driving cylinder drives the power motor to move toward the right transmission shaft and the external permanent magnetic coupling is used to form a linkage between the power motor output shaft and the right transmission shaft to transmit power to the right transmission shaft. The external permanent magnetic coupling can realize the clutch of the motor output shaft and the right transmission shaft, so that only one set of power components is needed to realize the transmission of the transmission components in each rain boot mold, which is lower in cost.

[0018] It is further configured as follows: it includes a primary injection molding mechanism, which includes an injection molding frame, a transmission channel formed on the injection molding frame and through which the rain boot mold passes, and an injection molding head that is lifted and lowered above the transmission channel, and a clamping component that drives the left lower mold and the right lower mold to press against each other is provided in the transmission channel.

[0019] By adopting the above technical solution, the rain boots mold is transmitted to the transmission channel, and the clamping component is used to further drive the left lower mold and the right lower mold to press against each other, so as to compensate for the tolerance formed between the assembly of parts, reduce the flash formed by the assembly gap during the injection molding process, and further improve the processing quality of the product.

[0020] It is further configured as follows: the clamping assembly includes clamping wheels slidably arranged on the two side walls of the transmission channel, clamping springs driving the two clamping wheels to move toward each other, and clamping rails arranged on the opposite sides of the left lower mold and the right lower mold, the positive projection path of the clamping rails along the horizontal direction corresponds to the clamping wheels, and the clamping rails include an inclined guide section and a clamping horizontal section in sequence along the transmission direction of the opposite transmission mechanism, and the inclined guide section is gradually inclined outward toward the direction of the clamping horizontal section.

[0021] By adopting the above technical solution, the clamping track is transmitted into the transmission channel along with the rain boots mold and contacts the clamping wheel, and the formed clamping horizontal section cooperates with the clamping spring to form mutual compression between the left lower mold and the right lower mold, so as to achieve the purpose of clamping. This setting structure does not require a driving source, has lower cost and is more energy-saving and environmentally friendly.

[0022] It is further configured as follows: the locking assembly includes a hook hinged to the left lower mold, a clamping rod fixedly arranged on the right lower mold and engaged with the hook, and a positioning spring for positioning the hook.

[0023] By adopting the above technical solution, the positioning spring is used to position the hook, so as to cooperate with the card rod to realize opening and closing.

[0024] In summary, the present invention has the following beneficial effects: the present invention can reduce the noise generated during the processing and reduce the wear of the rain boot mold, thereby improving the processing quality of the product and improving the working environment of the staff.
