Description

Technical Field

[0001] The present invention relates to the technical field of vehicle mold equipment, in particular to a vehicle spare tire bracket overlay molding device. Background Art

[0002] The spare tire bracket for a car is constructed from a shell-like frame structure and a pile blanket, which is laminated and molded. The pile blanket surface is composed of fleece and non-woven fabric. To maintain the overall aesthetics of the vehicle interior and reduce costs, a heating, laminating, and integrated molding process is employed during manufacturing and assembly. During the molding process, the gap between the frame and the pile blanket, as well as the shape, must be stable and controllable. Specifically, requirements require that the frame and the pile blanket, at irregular surfaces and square grooves, fit together without wrinkles or debonding, ensuring a smooth appearance. Smooth and consistent finish is a major challenge for automated tooling.

[0003] The current lamination molding process already has special mold tooling to assist the lamination process to ensure the bonding effect. The intermediate step of heating the skeleton to make the glue reach the appropriate working temperature for pasting is achieved through manual operation by skilled workers. This manual step requires a high level of worker proficiency and it is often difficult to achieve the best pasting and lamination effect. At the same time, there are also problems such as low process efficiency, safety hazards, uneven quality and high product scrap rate.

[0004] In summary, the existing overmolding process of the spare tire bracket for automobiles has technical problems such as low efficiency, poor quality and potential safety hazards. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing overlay molding process of the automobile spare tire bracket has the technical problems of low efficiency, poor quality and potential safety hazards.

[0006] In order to solve the above problems, the present invention provides a car spare tire bracket covering and molding equipment, including an upper mold assembly and a lower mold assembly for respectively placing the bracket skeleton blank to be bonded and the ready-to-use fleece blanket, the upper mold assembly and the lower mold assembly cooperate through the upper and lower molds of the mold bracket to press the ready-to-use fleece blanket against the surface of the bracket skeleton blank; the car spare tire bracket covering and molding equipment also includes a heating assembly, the heating assembly includes a first heating tube group whose distribution matches the outline and surface convex shape of the bracket skeleton blank and a transfer seat mechanism for installing and fixing the first heating tube group, the transfer seat mechanism is located between the upper mold assembly and the lower mold assembly in the vertical direction, and is laterally slidably cooperated with the mold bracket, and is used to align the lateral position of the heating tube group with the bracket skeleton blank placed by the upper mold assembly to heat the bracket skeleton blank, and reset the position of the heating assembly after heating is completed.

[0007] The present invention provides a spare tire bracket forming device that can automatically close the mold and cover, and can automatically heat to avoid manual heating operation. The overall structure follows the basic molding jig design, including an upper mold assembly and a lower mold assembly that can close the mold with each other to press the fleece blanket against the surface of the bracket frame. On the basis of this structure, a heating component is added to the mold equipment. The structure of the component that performs the specific heating function is a first heating tube group, which preferably uses the infrared heating principle, including a plurality of densely distributed infrared heating tubes. The distribution method of the heating tubes and the bending shape of each heating tube are adapted to the outline and surface convex shape of the bracket frame blank, so that the upper mold assembly is lowered to a height position suitable for heating through the upper mold after being connected to the bracket frame blank. The first heating tube group can achieve the purpose of heating the bracket frame. The bracket has a good heating effect. After the heating of the bracket skeleton blank is completed, the heating component is horizontally transferred through the transfer seat mechanism, leaving a vertical space between the upper mold component and the lower mold component to avoid interference with the mold closing action. The design can fully automate the spare tire bracket laminating process. The heating blank with poor manual operation effect in the original molding process is adapted to the process of gluing requirements. The automated equipment design can ensure the heating temperature is accurate, improve the gluing effect, and make the process automated and continuous. Compared with manual operation, the laminating molding efficiency is greatly improved, and the risk of burns to operators is avoided. It effectively solves the technical problems of low efficiency, poor quality and safety hazards in the existing laminating molding process of automobile spare tire brackets.

[0008] As a preferred solution, the heating assembly further includes a second heating tube group, which is arranged on the bottom surface of the transfer seat mechanism, and the first heating tube group is arranged on the top surface of the transfer seat mechanism, and the first heating tube group and the second heating tube group are symmetrical about the transverse midplane of the transfer seat mechanism, and the second heating tube group is used to work synchronously with the first heating tube group to heat the pile blanket and the bracket frame blank respectively.

[0009] This design further optimizes the above-mentioned heating component design, adapts to the above-mentioned first heating tube group, and arranges a symmetrical second heating tube group on the other side of the heating tube group. The two heating tube groups are respectively arranged on the two opposite end faces of the transfer seat mechanism. Through this design, when the transfer seat mechanism moves horizontally to the heating position, not only can the bracket skeleton blank be heated by the lowering of the upper mold assembly, but the second heating tube group can also be used to heat the pile blanket on the lower mold assembly below, ensuring that the temperature is evenly distributed on the two blanks to be laminated and formed, further improving the bonding effect of the glue.

[0010] As a preferred solution, the upper mold assembly includes an upper mold for positioning the bracket skeleton blank, the outer contour of the upper mold matches the shape of the bracket skeleton blank, and a constant temperature cooling pipeline is provided in the upper mold to keep the mold at a working temperature suitable for overlay molding during continuous operation.

[0011] This design optimizes the mold for the heating and gluing process. Since the upper mold of the upper mold assembly and the skeleton blank fixed to the upper mold are heated simultaneously by the heating tube group, the bracket skeleton will be removed after heating and gluing, while the upper mold will continue to be processed continuously. Continuous processing will cause the upper mold to be heated repeatedly for a long time, which can easily cause the mold temperature to overheat, affecting bonding and even damaging the upper mold. To protect the equipment, the only option is to reduce the molding process rate, which is not conducive to improving processing efficiency. Taking this into account, cooling pipes are installed in the upper mold to ensure that even high-frequency continuous heating will not cause the upper mold temperature to exceed the threshold, ensuring the continuity of the molding process.

[0012] As a preferred solution, the upper mold is provided with a clamp locking mechanism for positioning the bracket skeleton blank to be processed, the clamp locking mechanism includes a fastener extending from the surface of the upper mold and a clamp power part for driving the fastener to clamp or release the bracket skeleton blank, and the clamp power part is located on the side of the upper mold away from the molding surface.

[0013] This design improves the automation level of the mold device, mainly by optimizing the detailed structure of the upper mold, so that the upper mold can form a more stable positioning fit with the bracket skeleton blank, avoiding the bracket skeleton blank from falling off the upper mold during the movement of the mold. The output motion of the clamp power parts such as cylinders, oil cylinders or motors drives the movement of the fasteners, and cooperates with the surface of the upper mold to form a support and fixation for the blank, avoiding process errors and further improving the automation level of the processing technology.

[0014] As a preferred solution, the lower mold assembly includes a lower mold whose shape matches the concave and convex shape of the bracket skeleton blank, and a plurality of positioning needle mechanisms are distributed around the outer side of the lower mold, which can feed vertically to position the corners of the pile blanket located on the lower mold.

[0015] This design corresponds to the above-mentioned technical solution. The mold and the workpiece to be processed are also positioned when the pile blanket is placed on the lower mold. Multiple positioning pin mechanisms are provided around the outer periphery of the lower mold. These pins penetrate the edges of the pile blanket beyond the mold to secure the relative position between the pile blanket and the lower mold, preventing the pile blanket from being misaligned and resulting in defective products during the molding process. Based on this, a preferred positioning pin mechanism design is provided, including a positioning plate fixed to the base of the lower mold assembly, with through-holes provided on the positioning plate. Positioning pins capable of vertical feed are provided in conjunction with a needle plate. The vertical feed of the positioning pins penetrates the pile blanket and passes through the through-holes in the positioning plate to ensure secure positioning and prevent movement under pulling forces.

[0016] As a preferred solution, the lower mold assembly also includes a position detection switch located on one side of the lower mold, used to detect whether the support frame blank has reached the lower mold position during mold closing. This design improves the automation level of the molding equipment by providing a position detection switch. Located on the lower mold, it uses infrared, photoelectric, and other means to detect whether the support frame has reached the lower mold position. This structure provides a signal basis for feedback control, assisting in controlling when to stop the mold closing action and when to lock the mold position.

[0017] As a preferred solution, the mold support is surrounded by a protective outer frame. A safety light barrier is installed on the side of the protective outer frame where workers perform material loading and unloading operations. This mechanism uses photoelectric sensing to detect the presence of operators within the protective outer frame. This design provides a safety measure. While the equipment's processing is automated, loading and unloading are still performed manually. To prevent potential safety hazards to operators from mold closing and high temperatures generated by heating, a safety light barrier is installed. Using photoelectric principles, it senses personnel and movements within a preset range, ensuring that mold closing and heating are not initiated until personnel have retreated to a safe area.

[0018] As a preferred solution, the mold support includes a support body, a vertical transmission mechanism, and a lifting platform connected to the upper mold assembly. The lifting platform is provided with a drive motor for outputting rotational motion. The output end of the drive motor is connected to a transmission shaft and a transmission gear set. The vertical transmission mechanism includes a vertically arranged transmission rack and a mold clamping guide rail. The lifting platform and the mold clamping guide rail can slide in the vertical direction, and the transmission gear set is engaged with the transmission rack. This design provides a preferred mold clamping design, which outputs rotation through the drive motor and transmits the rotational motion to the transmission gears on both sides of the lifting platform through the transmission shaft. The gears are engaged with the vertical transmission racks on both sides of the lifting platform to convert the rotational motion into a stable and controllable vertical feed motion, thereby accurately controlling the lifting action of the lifting platform. A vertical mold clamping guide rail is also provided, and the guide rail provides a vertical sliding guide to ensure that the motion trajectory of the lifting platform is stable, limited to the vertical direction, and does not deviate in the horizontal plane.

[0019] As a preferred solution, the mold support further includes a mold closing locking mechanism, which includes a positioning rack parallel to the transmission rack and a positioning lock tongue member cooperating with the positioning rack. The positioning lock tongue member is arranged at the edge of the lifting platform and is connected to a pneumatic drive mechanism for driving the positioning lock tongue member to telescope, lock or unlock. The upper mold assembly is positioned at a height for closing the mold with the lower mold assembly through the locking cooperation between the positioning lock tongue member and the positioning rack. This design is aimed at the mold closing structure design of the upper mold assembly, and adds a structure for locking the vertical height of the upper mold assembly. The pneumatic drive mechanism outputs a linear feed to clamp the positioning lock tongue member to the teeth on the positioning rack, thereby fixing the height position of the lifting platform and the upper mold connected thereto. This design can maintain the relative position of the upper mold and the lower mold in the mold closing state, maintain the mold closing pressurization state, and help to ensure a tight fit between the pile blanket and the support frame.

[0020] As a preferred solution, the upper and lower mold assemblies each include two symmetrically spaced tire molds adapted to the spare tire support structure of an automobile. This design primarily adapts to the typical spare tire support structure of an automobile, which typically has two symmetrical support bodies. Therefore, the upper and lower mold assemblies of the molding equipment should each have two symmetrical tire mold structures. Based on this concept, the tire molds and the mold assembly base should be mounted in a manner that facilitates assembly and disassembly, facilitating the selection of adaptable tire molds for different product models.

[0027] A car spare tire bracket covering and molding equipment provided in this embodiment includes an upper mold assembly 1 and a lower mold assembly 2 for respectively placing a bracket skeleton blank to be bonded and a ready-to-use fleece blanket. The upper mold assembly 1 and the lower mold assembly 2 are matched with each other through a mold support 3 to press the ready-to-use fleece blanket onto the surface of the bracket skeleton blank; the car spare tire bracket covering and molding equipment also includes a heating assembly 4, the heating assembly 4 includes a first heating tube group 4-1 whose distribution matches the outline and surface concave-convex shape of the bracket skeleton blank and a transfer seat mechanism 4-2 for installing and fixing the first heating tube group 4-1. The transfer seat mechanism 4-2 is located between the upper mold assembly 1 and the lower mold assembly 2 in the vertical direction, and is laterally slidably matched with the mold support 3, and is used to align the lateral position of the heating tube group with the bracket skeleton blank placed by the upper mold assembly 1 to heat the bracket skeleton blank, and reset the position of the heating assembly 4 after heating is completed.

[0028] The present invention provides a spare tire bracket forming device that can automatically close the mold and cover, and can automatically heat to avoid manual heating operation. The overall structure follows the basic molding jig design, including an upper mold component 1 and a lower mold component 2 that can close the mold with each other to press the pile blanket against the surface of the bracket frame. On the basis of this structure, a heating component 4 is added to the mold equipment. The structure of this component that performs the specific heating function is a first heating tube group 4-1, which preferably uses the infrared heating principle, including a plurality of densely distributed infrared heating tubes. The distribution method of the heating tubes and the bending shape of each heating tube are adapted to the outline and surface convex shape of the bracket frame blank. After the upper mold component 1 is connected to the bracket frame blank, it is lowered to a height position suitable for heating through the upper mold. The first heating tube group 4-1 can achieve the support The frame has a good heating effect. After the heating of the bracket frame blank is completed, the heating component 4 is horizontally transferred through the transfer seat mechanism 4-2, leaving a vertical space between the upper mold component 1 and the lower mold component 2 to avoid interference with the mold closing action. The design can fully automate the spare tire bracket laminating process. The heating blank with poor manual operation effect in the original molding process can adapt to the process of gluing requirements. Through the automated equipment design, the heating temperature can be guaranteed to be accurate, the gluing effect is improved, and the process can be automated and continuous. Compared with manual operation, the laminating molding efficiency is greatly improved, and the risk of burns to operators is avoided. It effectively solves the technical problems of low efficiency, poor quality and safety hazards in the existing laminating molding process of automobile spare tire brackets.

[0029] In the technical solution provided in this embodiment, the heating assembly 4 also includes a second heating tube group 4-3, which is arranged on the bottom surface of the transfer seat mechanism 4-2, and the first heating tube group 4-1 is arranged on the top surface of the transfer seat mechanism 4-2. The first heating tube group 4-1 and the second heating tube group 4-3 are symmetrical about the transverse midplane of the transfer seat mechanism 4-2. The second heating tube group 4-3 is used to work synchronously with the first heating tube group 4-1 to heat the pile blanket and the bracket frame blank respectively.

[0030] This design further optimizes the design of the above-mentioned heating assembly 4, adapts to the above-mentioned first heating tube group 4-1, and sets a symmetrical second heating tube group 4-3 on the other side of the heating tube group. The two heating tube groups are respectively set on the two opposite end faces of the transfer seat mechanism 4-2. Through this design, when the transfer seat mechanism 4-2 moves horizontally to the heating position, it can not only heat the bracket skeleton blank by lowering the upper mold assembly 1, but also simultaneously heat the pile blanket on the lower mold assembly 2 below through the second heating tube group 4-3, ensuring that the temperature is evenly distributed on the two blanks to be laminated and formed, further improving the bonding effect of the glue.

[0031] In the technical solution provided in this embodiment, the upper mold assembly 1 includes an upper mold 1-1 for positioning the bracket skeleton blank. The outer contour of the upper mold 1-1 matches the shape of the bracket skeleton blank. A constant temperature cooling pipeline is provided in the upper mold 1-1 to keep the mold at a working temperature suitable for overlay molding during continuous operation.

[0032] This design optimizes the mold for the heating and gluing process. Because the upper mold 1-1 of the upper mold assembly 1 and the skeleton blank fixed to the upper mold 1-1 are heated simultaneously by the heating tube group, the bracket skeleton is removed after heating and gluing, while the upper mold 1-1 continues to be processed continuously. Continuous processing causes the upper mold 1-1 to be heated repeatedly for a long time, which can easily cause the mold temperature to overheat, affecting bonding and even damaging the upper mold 1-1. To protect the equipment, the only option is to reduce the molding process rate, which is not conducive to improving processing efficiency. Considering this situation, a cooling pipeline is installed in the upper mold 1-1 to ensure that even high-frequency continuous heating will not cause the temperature of the upper mold 1-1 to exceed the threshold, ensuring the continuity of the molding process.

[0033] In the technical solution provided in this embodiment, the upper mold 1-1 is provided with a clamp locking mechanism for positioning the bracket skeleton blank to be processed. The clamp locking mechanism includes a fastener 1-2 extending from the surface of the upper mold 1-1 and a clamp power part 1-3 for driving the fastener 1-2 to clamp or loosen the bracket skeleton blank. The clamp power part 1-3 is located on the side of the upper mold 1-1 away from the forming surface.

[0034] This design improves the degree of automation of the mold device, mainly by optimizing the detailed structure of the upper mold 1-1, so that the upper mold 1-1 can form a more stable positioning fit with the bracket skeleton blank, avoiding the bracket skeleton blank from falling off from the upper mold 1-1 during the movement of the mold, and outputting motion through the clamp power parts 1-3 such as cylinders, oil cylinders or motors to drive the movement of the fastener 1-2, and cooperating with the surface of the upper mold 1-1 to form a support and fixation for the blank, avoiding process errors and further improving the degree of automation of the processing technology.

[0035] In the technical solution provided in this embodiment, the lower mold assembly 2 includes a lower mold 2-1 whose shape matches the concave and convex shape of the bracket skeleton blank, and a plurality of positioning needle mechanisms 2-2 are distributed around the outer side of the lower mold 2-1, which can feed in the vertical direction to position the corners of the pile blanket located on the lower mold 2-1.

[0036] This design corresponds to the above-mentioned technical solution. The mold and the workpiece to be processed are also positioned when the pile blanket is placed on the lower mold 2-1. Multiple positioning pin mechanisms 2-2 are provided around the outer periphery of the lower mold 2-1. These pin mechanisms penetrate the pile blanket beyond the edges of the mold to secure the relative position between the pile blanket and the lower mold 2-1, thereby preventing the pile blanket from being misaligned and resulting in defective products during the molding process. On this basis, a preferred design for the positioning pin mechanism 2-2 is provided, comprising a positioning plate fixed to the base of the lower mold assembly 2. The positioning plate is provided with through holes, and positioning pins capable of vertical feed are provided in conjunction with a needle plate. The positioning pins are vertically fed through the pile blanket and through the through holes in the positioning plate to ensure secure positioning and prevent movement under pulling forces.

[0037] In the technical solution provided in this embodiment, the lower mold assembly 2 also includes a position detection switch 2-3 located on one side of the lower mold 2-1, which is used to detect whether the support frame blank has reached the lower mold 2-1 during mold closing. This design improves the automation level of the molding equipment by providing a position detection switch 2-3. Located on the lower mold 2-1, it detects whether the support frame has reached the lower mold 2-1 through infrared, photoelectric, or other means. This structure provides a signal basis for feedback control, assisting in controlling when to stop the mold closing action and when to lock the mold position.

[0038] In the technical solution provided in this embodiment, a protective outer frame 5 is provided around the mold support 3. A safety light barrier mechanism 5-1 is installed on the side of the protective outer frame 5 where workers perform material loading and unloading operations. This mechanism uses photoelectric sensing to detect the presence of operators within the protective outer frame 5. This design provides a safety measure. Because the equipment's processing is automated, while loading and unloading are still performed manually, the safety light barrier is installed to prevent potential safety hazards to operators caused by mold closing and high temperatures generated by heating. This light barrier uses photoelectric sensing to detect personnel and movements within a preset range, ensuring that mold closing and heating are not initiated until personnel have retreated to a safe area.

[0039] In the technical solution provided in this embodiment, the mold bracket 3 includes a bracket body 3-2, a vertical transmission mechanism and a lifting platform 3-1 connected to the upper mold assembly 1.

The output end of the drive motor 3-3 is connected to a transmission shaft 3-4 and a transmission gear set 3-7. The vertical transmission mechanism includes a vertically arranged transmission rack 3-6 and a mold closing guide rail 3-5. The lifting platform 3-1 and the mold closing guide rail 3-5 can be slidably matched in the vertical direction, and the transmission gear set 3-7 is engaged with the transmission rack 3-6. This design provides an optimal mold closing design, which outputs rotation through the driving motor 3-3, and transmits the rotational motion to the transmission gears on both sides of the lifting platform 3-1 through the transmission shaft 3-4. The gears engage with the vertical transmission racks 3-6 on both sides of the lifting platform 3-1 to convert the rotational motion into a stable and controllable vertical feed motion, thereby accurately controlling the lifting action of the lifting platform 3-1, and also providing a vertical mold closing guide rail 3-5. The guide rail provides a vertical sliding guide to ensure that the motion trajectory of the lifting platform 3-1 is stable, limited to the vertical direction, and does not deviate in the horizontal plane.

[0040] In the technical solution provided in this embodiment, the mold support 3 also includes a mold closing locking mechanism, which includes a positioning rack 3-8 parallel to the transmission rack 3-6 and a positioning lock tongue member 3-9 cooperating with the positioning rack 3-8. The positioning lock tongue member 3-9 is arranged on the edge of the lifting platform 3-1 and is connected to a pneumatic drive mechanism 3-10 for driving the positioning lock tongue member 3-9 to telescope, lock or unlock. The upper mold assembly 1 is positioned at the height for closing the mold with the lower mold assembly 2 through the locking cooperation between the positioning lock tongue member 3-9 and the positioning rack 3-8. This design is aimed at the mold closing structure design of the upper mold assembly 1, and adds a structure for locking the vertical height of the upper mold assembly 1. The pneumatic drive mechanism 3-10 outputs linear feed, and the positioning lock tongue member 3-9 is clamped to the teeth on the positioning rack 3-8, thereby fixing the height position of the lifting platform 3-1 and the upper tire mold 1-1 connected to it. Through such a design, the relative position of the mold closing between the upper tire mold 1-1 and the lower tire mold 2-1 can be maintained, and the mold closing pressurization state can be maintained, which helps to make the pile blanket and the bracket frame fit tightly.

[0041] In the technical solution provided in this embodiment, both the upper mold assembly 1 and the lower mold assembly 2 include two symmetrically spaced tire molds adapted to the spare tire support structure of an automobile. This design primarily adapts to the typical spare tire support structure of an automobile, which typically has two symmetrical support bodies. Therefore, the upper mold assembly 1 and the lower mold assembly 2 of the molding equipment should each have two symmetrical tire mold structures. Based on this concept, the tire mold 1-1 and the mold assembly base should be mounted in a manner that facilitates assembly and disassembly, facilitating the selection of adaptive tire molds for different product models.
