Description

Technical Field

[0001] This invention relates to the field of drip molding technology, specifically to a drip molding device and process for a drip molded object. Background Technology

[0002] Drip molding technology utilizes the variable state property of thermoplastic polymers—that is, they exhibit viscous flow under certain conditions and can revert to a solid state at room temperature. Using appropriate methods and specialized tools, ink is sprayed into the desired shape in its viscous flow state, and then cured at room temperature. Drip molding is widely used in the decoration of various trademarks, nameplates, cards, daily hardware products, tourist souvenir badges, fine handicrafts, and high-end notebook covers.

[0003] Among the existing drip molding equipment technologies, the multi-purpose drip molding machine with announcement number CN101177030A is the subject of this invention. The purpose of this invention is to provide a multi-purpose drip molding machine with a simple structure and low manufacturing cost, in order to overcome the various shortcomings of the existing technology. This invention relates to a two-stage drying device controlled by pneumatic, electric, or hydraulic components. The left side moves, and the movement of the mold in and out of the drying chamber is controlled by pneumatic or hydraulic components. The device performs dripping in stages, controlling the drying and heat dissipation during each stage. The operator injects the dripping at a set intermediate position, applying it according to different colored liquid plastics to various mold patterns. Furthermore, it describes a novel injection molding process for spot casting molds (publication number CN103203833A) that places a template on a substrate, then places the substrate on a specialized extruder / drip machine / casting machine to fill the various shaped gaps on the template with plastic. A transparent film is then placed on the plastic-filled template. The plastic-filled template is removed from the substrate and finally placed on an ejector plate. The ejector plate then ejects the molded plastic product. Because of the transparent film on the product, all the plastic products adhere to the film and are ejected together. It features different convex and concave molds on the same mold, allowing for the production of plastic products of different shapes from a single mold, thus improving production efficiency. However, the aforementioned patent still has some issues: 1. Existing drip molding equipment cannot eject the standard mold through ejector pins at the same time as mold opening, which cannot speed up the mold removal process and thus reduces work efficiency.

[0004] 2. Existing drip molding equipment cannot automatically switch between drawing machines and gold powder spraying machines, reducing the degree of automation and increasing the labor force.

[0005] 3. Existing drip molding equipment does not have a cooling device, which makes it impossible to speed up the molding rate of the target. Summary of the Invention

[0013] Preferably, both the third and fourth molding dies have a second cooling pipe at the end closest to the convex material.

[0016] A molding process for drip-molded labels includes the following steps: Step 1: Move the device to the work site and fix it. The worker can move the device to the work site using the self-locking casters, and then fix the self-locking casters by their self-locking ability. Step Two: Injection Molding of the Convex Material. The worker can use a remote control to start the first injection molding machine, injecting the material into the first and second molding molds through the first conduit. The convex material is then cooled by the first cooling pipe and cooling block. The worker can then use the remote control to start the lifting motor, which raises the second molding mold and simultaneously causes several evenly distributed ejector pins to push the convex material downwards, thus creating the convex surface. The lifting motor drives the lifting motor shaft to rotate, which in turn drives gears to mesh and rotate within the slide frame. This gear meshing and rotation within the slide frame moves the second molding mold upwards. Simultaneously, the gear rotation drives the second transmission shaft to rotate, which in turn drives the sleeve to rotate. The sleeve's rotation drives the first transmission disc to rotate, which in turn drives... The second transmission disk rotates, which drives the first transmission shaft to rotate. The first transmission shaft rotates, which drives the cam to rotate. The cam rotates, which drives the rotating shaft to rotate and moves the ejector plate downward. At this time, the coil spring is in a compressed state. The ejector plate moves downward, pushing the ejector pin downward to push out the convex surface. Then, the worker can use a remote control to activate the first hydraulic cylinder to move the first push rod to one end. The first push rod moves to one end, which drives the second lifting lug to one end. The second lifting lug moves to one end, which drives the crank to rotate. The crank rotates, which drives the first lifting lug to one end. The first lifting lug moves to one end, which drives the fixed plate to one end, thus disengaging the first transmission disk from the second transmission disk. Due to the tension of the coil spring, the cam will return to its original position, completing the function of the ejector pin lifting mechanism. Step 3: To create a pattern on the convex material, the worker can place the convex material into the third forming mold and keep the mold open. Then, the worker can use a remote control to activate the third hydraulic cylinder and the rotary motor. The third hydraulic cylinder drives the third push rod to move up and down, thereby adjusting the pattern-making machine up and down. The rotary motor drives the rotary motor shaft to rotate, and the rotary motor shaft rotates the rotary gear, thereby adjusting the pattern-making machine back and forth. This allows the pattern-making machine to be moved to the appropriate position on the top of the convex material and then create the pattern. Step 4: Inject the bottom material of the logo onto the outside of the decal. The worker can use a remote control to activate the symmetrically distributed first hydraulic cylinder to drive the third and fourth molding molds to close the mold and start the second injection molding machine to inject the material into the convex material of the logo and the top of the decal through the second conduit. The injection material should cover the decal and be injected to a certain height. Step 5: Spray gold powder onto the base material. The worker can use a remote control to open the third and fourth forming molds, and then use the remote control to start the rotating motor to drive the gold powder spraying machine and the drawing machine to switch positions and spray gold powder onto the base material. The rotating motor drives the rotating motor shaft to rotate, which in turn drives the concave disc to rotate. The concave disc rotates, which in turn drives the symmetrically distributed pins to rotate. The symmetrically distributed pins rotate and are inserted into the U-shaped slide, which in turn drives the irregularly shaped turntable to rotate. The irregularly shaped turntable rotates, which in turn drives the rotating shaft to rotate. The rotating shaft rotates, which in turn drives the circular plate to rotate. The circular plate rotates, which in turn drives the rectangular sleeve plate to rotate, thus realizing the switching of the gold powder spraying machine and the drawing machine and completing the intermittent mechanism function. Step Six: Continue to inject the bottom material of the label onto the gold powder to seal it. The worker uses a remote control to close the third and fourth molding molds again, and then injects the top of the gold powder onto the second injection molding machine to seal it. Finally, the label is cooled by the symmetrically distributed second cooling pipes to complete the molding of the label.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The device is equipped with a lifting ejector mechanism. The worker can use a remote control to start the lifting motor to drive the second molding die to rise. At the same time, it will drive several evenly distributed ejector pins to push the standard convex material downward to obtain the standard convex surface. The standard model can be pushed out by the ejector pins at the same time as the mold is opened, which speeds up the mold removal speed and thus increases work efficiency.

[0018] 2. The device is equipped with an intermittent mechanism. The worker can start the rotating motor with a remote control to switch the gold powder spraying machine and the graffito machine and spray gold powder onto the bottom material. This can realize the automatic switching between the graffito machine and the gold powder spraying machine, increase the degree of automation and reduce the labor force of workers.

[0019] 3. The device is equipped with a first cooling pipe, a second cooling pipe and a cooling block, which can accelerate the molding rate of the target. Attached Figure Description

The rotary motor 72 drives the rotary motor shaft 73 to rotate. The rotation of the rotary motor shaft 73 drives the rotary gear 71 to rotate, thereby driving the pattern machine 75 to adjust back and forth, so that the pattern machine 75 is moved to the appropriate position on the upper end of the convex material 24 and the pattern 25 is applied. Step 4: Inject the bottom material 26 of the label onto the outside of the pull flower 25. The worker can use a remote control to open the symmetrically distributed first hydraulic cylinder 15 to drive the third molding mold 12 and the fourth molding mold 13 to close the mold and open the second injection molding machine 16 to inject the injection material into the convex material 24 and the upper end of the pull flower 25 through the second conduit 21. The injection material should cover the pull flower 25 and be injected to a certain height. Step 5: Spray gold powder 23 onto the bottom surface material 26. The worker can open the mold by using a remote control to open the third forming mold 12 and the fourth forming mold 13. Then, the worker can turn on the rotating motor 77 by using a remote control to drive the gold powder spraying machine 76 and the flower drawing machine 75 to switch positions and spray gold powder 23 onto the bottom surface material 26. Step Six: Continue to inject the bottom material 26 of the label onto the gold powder 23 to seal it. The worker uses a remote control to close the third molding mold 12 and the fourth molding mold 13 again, and then injects the top of the gold powder 23 onto the second injection molding machine 16 to seal it. Then, it is cooled by the symmetrically distributed second cooling pipes 70 to complete the label molding. This completes the function of a drip-molded label molding equipment.
