Description

Technical Field

[0001] The invention relates to the technical field of toy processing equipment, in particular to an oil-spraying top mold device. Background Art

[0002] During the toy processing process, multiple local parts need to be sprayed with different colors or materials. During the process, the toy to be processed needs to be pushed to the spraying position through a lifting mechanism, so that other parts of the toy are protected by the mold, and then the parts to be sprayed can be sprayed with oil.

[0003] In the existing top mold device, only the mold is used to protect the parts of the toy that do not need to be sprayed with oil. During the lifting process, the toy is not protected. In order to prevent the spray gun from spraying oil prematurely or dripping oil, the spray gun needs to be moved away first. After the lifting mechanism lifts the toy to fit the mold, the spray gun is moved to the top of the toy for spraying oil. This process is cumbersome and requires workers to constantly move the spray gun, which is time-consuming and labor-intensive, and has low production efficiency. Summary of the Invention

[0036] Reference Figures 1 to 4 According to an embodiment of the present invention, the oil injection top mold device includes a lifting device 100, including a support member 110 and a lifting member 120, and the lifting member 120 is arranged on the support member 110; the mold frame 200 includes a top plate 210 and a bottom plate 220, four hollow support columns 230 are arranged between the top plate 210 and the bottom plate 220, the bottom plate 220 is arranged on the lifting member 120, and a protective mold 211 is arranged on the top plate 210. A protective cover 240 is also hinged on the top plate 210, and a reset member is provided at the hinge of the protective cover 240 and the top plate 210. The positioning parts make the protective cover 240 always have a tendency to rotate upward; the top template 300 is movably arranged between the top plate 210 and the bottom plate 220, and the lifting part 120 can drive the top template 300 to move up and down between the top plate 210 and the bottom plate 220; the flexible connecting part 400 is arranged in the support column 230, and the support column 230 is provided with an opening 231. One end of the flexible connecting part 400 passes through the opening 231 and is connected to the lower end of the top template 300, and the other end extends from the top of the support column 230 and is connected to the end of the protective cover 240 away from the hinge.

[0037] In the above embodiment, it should be noted that, among the four hollow support columns 230, the upper ends of the two support columns away from the hinge pass through the top plate 210, and the hollow inner cavity thereof is connected to the upper end of the top plate 210, and the flexible connector 400 can pass through it. The reset member makes the protective cover 240 always have a tendency to rotate upward. Figure 1 and Figure 2 The process shown is counterclockwise rotation.

[0038] The movement process of the above embodiment is as follows: when preparing to spray the toy with oil, a corresponding protective mold 211 is placed on the top plate 210. The shape of the protective mold 211 is similar to the shape of the upper end of the toy. At the same time, there is a baffle at the position where oil spraying is not required, and a yielding portion at the position where oil spraying is required. Then the toy is placed on the top template 300. At this time, the top template 300 is at the lowest position, the flexible connector 400 is tightened, and the protective cover 240 is simultaneously pulled by the flexible connector 400 to fit on the top plate 210. The lifting member 120 drives the top template 300 to move upward, and the flexible connector 400 begins to relax. Under the action of the reset member, the protective cover 240 also begins to rotate upward until the top template 300 is displaced upward to the maximum position. At this time, the upper end of the toy abuts the protective mold 211, the flexible connector 400 is tightened again, the protective cover 240 no longer rotates, and the spray gun starts to spray oil.

[0039] The oil-spraying top mold device according to the embodiment of the present invention has at least the following beneficial effects: when the lifting member 120 drives the top template 300 to the lowest position, under the traction of the flexible connecting member 400, the protective cover 240 rotates downward until it is in contact with the top plate 210, thereby covering the protective mold 211, to prevent the spray gun from spraying oil prematurely or leaking oil onto the toy during the process; when the lifting member 120 drives the top template 300 to rise, the flexible connecting member 400 moves upward synchronously, at which time the flexible connecting member 400 remains in a relaxed state; under the action of the reset member, the protective cover 240 begins to rotate upward until the top template 300 rises to the protective mold 211; after the protective cover 240 opens to the maximum position, the flexible connecting member 400 is tightened; at this time, the protective cover 240 is no longer opened, and the spray gun starts to spray oil; under the action of the protective mold 211, oil will only be sprayed onto the exposed surface of the toy, and will not be sprayed onto other positions.

[0040] According to some embodiments of the present invention, the reset member is configured as a torsion spring, which allows the protective cover 240 to always have a tendency to rotate counterclockwise, and the protective cover 240 stops rotating after the torsion spring is fully reset.

[0041] According to some embodiments of the present invention, the flexible connector 400 is configured as a nylon rope or a twisted metal wire rope, which has a certain degree of flexibility and sufficient strength and is not easily broken.

[0042] According to some embodiments of the present invention, referring to Figures 1 to 4 There are two flexible connectors 400, and the two flexible connectors 400 are respectively arranged in the two support columns 230. The two flexible connectors 400 make the pulling force more uniform and are not prone to breakage.

[0043] According to some embodiments of the present invention, referring to Figures 1 to 4A fixing part 310 is provided below the top template 300, and the fixing part 310 is threadedly connected to the top template 300. A hanging rope part 311 is provided on the fixing part 310. The fixing part 310 connected by threads is convenient for disassembly and assembly. The hanging rope part 311 is in a semicircular shape and can be obtained by tying one end of the flexible connector 400 to the hanging rope part 311.

[0044] According to some embodiments of the present invention, referring to Figures 1 to 4 , also includes a buffer assembly 500, the buffer assembly 500 is movably arranged between the top plate 210 and the bottom plate 220, the output shaft of the jacking member 120 passes through the bottom plate 220 to connect the buffer assembly 500, and the top template 300 is movably arranged on the buffer assembly 500. The buffer assembly 500 can slowly apply pressure to the top template 300 so that the top template 300 is close to the protective mold 211. During the jacking process, the top template 300 drives the toy to contact the protective mold 211 first. At this time, the jacking member 120 continues to rise. Under the action of the buffer assembly 500, the toy gradually fits with the protective mold 211 to avoid the generation of excess gaps that cause oil to leak to other surfaces of the toy.

[0045] In the above embodiment, referring to Figures 1 to 4 The buffer assembly 500 includes a pressure plate 510, a plurality of guide columns 520 and a plurality of elastic members 530. The output shaft of the lifting member 120 is connected to the lower end of the pressure plate 510, the upper end of the guide column 520 is connected to the top template 300, and the lower end passes through the clearance hole on the pressure plate 510. The elastic member 530 is sleeved on the guide column 520, one end abuts the top template 300, and the other end abuts the pressure plate 510. During the rising process of the lifting member 120, after the toy contacts the protective mold 211, the pressure plate 510 continues to move upward under the drive of the lifting member 120. Under the action of the elastic member 530, the upward force is slowly transmitted to the toy, so that the rigid conduction is transformed into flexible conduction. The toy gradually fits tightly against the protective mold 211, reducing the gap between the protective mold 211 to prevent oil leakage to other surfaces of the toy.

[0046] According to some embodiments of the present invention, the elastic member 530 is configured as a spring or a rubber block.

[0047] According to some embodiments of the present invention, referring to Figures 1 to 4 , also includes memory foam 600, which is arranged above the top template 300. The memory foam can make the bottom of the toy form a flexible contact with the top template 300, which can further prevent the toy from being squeezed.
