[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The present invention provides a lifting type extrusion molding machine, comprising a machine base 100, a first lifting plate 210 and an extrusion barrel 300. The machine base 100 is provided with a workbench 111, which is suitable for supporting the mold so that the grouting port of the mold faces upward. The first lifting plate 210 is located above the workbench 111 and is connected to the machine base 100 through a first cylinder 220. The extrusion barrel 300 comprises a melt barrel 310, an extrusion piston 320 and an extrusion cylinder 330. The upper and lower ends of the melt barrel 310 are respectively provided with a plastic pellet inlet 3 11 and the glue extrusion nozzle 312, the peripheral wall of the melt glue cylinder 310 is provided with an electric heating element 340, the extrusion piston 320 is adapted to be arranged in the melt glue cylinder 310 and connected to the extrusion cylinder body 330, the extrusion cylinder body 330 and the melt glue cylinder 310 are both connected to the first lifting plate 210, the first cylinder body 220 is suitable for driving the extrusion cylinder 300 to rise and fall, so that the glue extrusion nozzle 312 of the melt glue cylinder 310 is docked with or away from the grouting port of the mold, and the extrusion cylinder body 330 is suitable for pushing the material in the melt glue cylinder 310 downward through the extrusion piston 320.

[0032] It is understood that the first cylinder 220 and the extrusion cylinder 330 can be pneumatic, hydraulic, or electric cylinders; the motor and the screw-nut pair / gear rack / belt combination are equivalent replacements. The electric heating element 340 is a resistor element that generates heat when energized. The electric heating element 340 is provided with a resistance wire or resistance bar, which is common knowledge in physics.

[0033] Reference Figures 1 to 3After the extrusion piston 320 begins to push down the material in the melt cylinder 310, the pellet inlet 311 cannot feed material to the lower end of the melt cylinder 310. Therefore, the extruder 300 operates in a single-shot, single-melt mode. After a single shot of pellets is poured into the melt cylinder 310 and melted for extrusion, the extrusion piston 320 moves upward away from the pellet inlet 311 to allow for the injection of new pellets. Therefore, this single-shot, single-melt extrusion molding machine is more suitable for mold testing and small-volume extrusion production.

[0034] The operation process of the present invention is as follows: the mold is placed on the workbench 111, and the mold is even fixed to the workbench 111 by screws and pressure plates, so that the mold grouting port is located directly below the glue extrusion nozzle 312; the extrusion piston 320 is lifted up to make way, so that the glue particle inlet 311 can input a single glue particle into the melt glue cylinder 310 (in the mold test, the amount of a single glue particle can be determined according to the size of the mold molding cavity); the first cylinder body 220 drives the extrusion cylinder 300 to descend as a whole, so that the glue extrusion nozzle 312 of the melt glue cylinder 310 docks the grouting port of the mold; the electric heating element 340 is energized and heated, so that the melt glue cylinder 310 and the glue particles inside it are heated. The glue particles are heated and melted into glue; the extrusion piston 320 is pressed down, and the glue is squeezed into the molding cavity of the mold through the grouting port; after the molding cavity of the mold is filled with glue (that is, when there are signs of glue spitting back between the grouting port and the glue extrusion nozzle 312; or it is judged according to the size of the molding cavity and the extrusion rate), the extrusion piston 320 stops pressing down, and even stops the power supply of the electric heating element 340, and the extrusion cylinder 300 is lifted up and away from the mold as a whole, and the mold is removed from the workbench 111 to open the mold and judge the molding quality of the product; the glue extrusion nozzle 312 away from the mold can be cleaned (and / or cleaned before moving down for extrusion in a new extrusion work).

[0035] Compared with the prior art, the beneficial effects of the present application include: the extension direction of the extrusion cylinder 300 and the extrusion direction of the slurry are in the up-down direction, the extrusion cylinder 300 and the mold are distributed in the up-down direction, the mold can be simply supported on the workbench 111, and the extrusion cylinder 300 and the mold can be quickly and conveniently separated through the first cylinder body 220, which is convenient for frequent replacement of test molds, frequent replacement of molds for small-scale product extrusion, and convenient for cleaning the slurry extrusion nozzle 312 when the mold is replaced; the mold is suitable for completing experimental single extrusion and small-scale product extrusion, and the extrusion cylinder 300 can melt and extrude the glue piece by piece to avoid continuous filling and melting of excess glue particles.

[0036] Reference Figure 1In some embodiments of the present invention, the machine base 100 includes a base 110, a mold opening cylinder body and a first mounting plate 120. The first mounting plate 120 is located above the base 110, and the mold opening cylinder body is arranged in the base 110. The piston rod of the mold opening cylinder body extends upward and is connected to the first mounting plate 120. The upper end of the base 110 is set to a workbench 111. The static mold of the mold is connected to the workbench 111 by screws. The movable mold of the mold is set at the lower end of the first mounting plate 120. The first mounting plate 120 is provided with a window 121 corresponding to the grouting port. The first lifting plate 210 is connected to the upper end of the first mounting plate 120 through the first cylinder body 220. In the present invention, the mold opening cylinder is suitable for driving the static mold and the dynamic mold of the mold to merge or separate, and the separation of the extrusion cylinder 300 and the mold is also relatively convenient. The machine base 100 mainly consists of a base 110 and a first mounting plate 120. The machine base 100 is relatively simple, and the mold is connected to the simple machine base 100 by screws. The disassembly and assembly of the mold is also relatively convenient, and mechanical opening and closing of the mold is also realized. When a small amount of product is extruded, the labor intensity of the operator is reduced.

[0037] Reference Figure 1 In some embodiments of the present invention, a guiding rod 230 is further included. The upper and lower ends of the guiding rod 230 are fixedly connected to the outer shell of the extrusion cylinder 330 and the first lifting plate 210 through nuts respectively. The piston rod of the extrusion cylinder 330 is connected to the extrusion piston 320 through a slider 240. The slider 240 is suitable for directional lifting along the guiding rod 230. In the present invention, the guiding rod 230 is suitable for fixing the extrusion cylinder 330 and is also suitable for serving as a guide rod, which effectively simplifies the structure of the extrusion molding machine. Figure 1 The upper end of the guide rod 230 and the nut together clamp the shell of the extrusion cylinder 330, and the lower end of the guide rod 230 and the nut together clamp the first lifting plate 210

[0038] In some embodiments of the present invention, the upper end opening of the melt cylinder 310 is suitable for the entry and exit of the extrusion piston 320 and is also suitable for the pellet inlet 311. When the extrusion piston 320 is completely separated from the melt cylinder 310, the pellets are filled into the melt cylinder 310 through this port.

[0039] Reference Figures 1 to 3 In some embodiments of the present invention, a hopper 400 is further included. The glue melt cylinder 310 is integrally formed with a fork tube. The fork tube has a glue pellet inlet 311. The drop-out port of the hopper 400 is suitable for connecting with the fork tube. The extrusion piston 320 is set to a predetermined length. The extrusion piston 320 is suitable for keeping the fork tube closed during the downward extrusion process. The glue melt cylinder 310 can be easily filled with glue pellets through the hopper 400. When the extrusion piston 320 is lifted up and leaves the fork tube but not completely separated from the glue melt cylinder 310, the glue melt cylinder 310 can be filled with glue pellets.

[0040] Reference Figure 3In some embodiments of the present invention, the fork tube is movably connected to a baffle 313, which is adapted to slide laterally along the fork tube to open or close the fork tube. It is understood that when the baffle 313 closes the fork tube, it is adapted to stop the feeding of the rubber pellets. In the present invention, the hopper 400 can buffer a large amount of rubber pellets, and the baffle 313 controls the filling of the rubber pellets into the melt cylinder 310.

[0041] Reference Figures 1 to 3 In some embodiments of the present invention, the fork tube is screwed to the lower end of the hopper 400. A chute 314 is provided at the end of the fork tube that interfaces with the hopper 400. A baffle 313 is adapted to slide along the chute 314 to open or close the fork tube, and the hopper 400 is adapted to cover the chute 314. In the present invention, the design of the chute 314 is relatively simple and convenient, yet effectively ensures the slidability and easy assembly and disassembly of the baffle 313.

[0042] Reference Figures 2 to 4 In some embodiments of the present invention, the electric heating element 340 includes a resistive heating strip and two C-shaped clamps. At least one of the C-shaped clamps is plugged into the resistive heating strip, and the two C-shaped clamps are connected by screws to jointly clamp the adhesive melt cartridge 310. The adhesive melt cartridge 310, C-shaped clamps, and resistive heating strip are removable and replaceable, making assembly and disassembly convenient and easy to maintain.

[0043] Reference Figures 1 to 3 In some embodiments of the present invention, a first protrusion 315 is provided at the upper end of the adhesive cartridge 310, through which the adhesive cartridge 310 is suspended from the first lifting plate 210. The first protrusion 315 is connected to the first lifting plate 210 via screws. A second protrusion 316 is provided at the lower end of the adhesive cartridge 310, which is suitable for supporting two C-shaped clamps. In the present invention, the adhesive cartridge 310 is supported on the first lifting plate 210, completing the initial installation of the adhesive cartridge 310 and allowing it to be easily locked and secured. The electric heating element 340 is connected to the lower end of the adhesive cartridge 310 in a supporting and clamping manner, making it easier to install and remove the electric heating element 340, without having to bend over to install the electric heating element 340 on the lower end surface of the first lifting plate 210.

[0044] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the C-shaped sheet has a double-walled, sandwiched cavity structure. A resistive heating strip is inserted into the inner wall of the C-shaped sheet. The sandwiched cavities 341 of the two C-shaped sheets are combined to form an insulating cavity for the electric heating element 340. In the present invention, the provision of an insulating cavity fully applies the heat of the electric heating element 340 to the melt glue cylinder 310, rapidly melting each glue pellet in the melt glue cylinder 310.

[0045] Reference Figures 1 to 3In some embodiments of the present invention, a protective heat collection cover 500 is connected to the lower end of the first lifting plate 210. The protective heat collection cover 500 is suitable for surrounding the electric heating element 340. A heat collection chamber is defined between the protective heat collection cover 500 and the electric heating element 340. The lower end of the heat collection chamber is open. The first lifting plate 210 is provided with a hot gas riser hole 211 suitable for communicating with the heat collection chamber. The hot gas riser hole 211 is connected to the corresponding port of the fork tube through a pipe. The port of the fork tube is provided with a rubber particle stop net. Simultaneously, based on the rising property of hot gas, in the present invention, the heat dissipated outward from the electric heating element 340 can be circulated to the fork tube and the hopper 400. This portion of the heat from the electric heating element 340 is channeled into the pile of rubber particles in the hopper 400, thereby drying or preheating the rubber particles. It can be understood that this portion of heat is relatively small and will not cause the rubber particles in the hopper 400 to melt.

[0046] Reference Figures 1 to 3 Better yet, the protective heat collecting cover 500 is composed of two parts, and when the protective heat collecting cover 500 is disassembled, there is no need to raise the first lifting plate 210 and other series of components too high.

[0047] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.
