Description

Technical Field

[0001] The utility model relates to the technical field of plastic roller processing, in particular to a model disassembly device used for plastic roller processing. Background Art

[0002] Plastic rollers are a type of sports equipment and are often used on the bottom of chairs, etc. Plastic rollers often require injection molding during production.

[0003] However, when traditional plastic wheels are injected, it is difficult to disassemble the mold, and the temperature of the newly injected plastic roller itself is relatively high, which can easily burn the workers. In addition, the outer edge of the plastic ring needs to be chamfered after injection molding, which increases the processing steps and time.

[0004] Therefore, it is urgent to propose a model disassembly device for plastic roller processing to solve the technical problems existing in the above-mentioned prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a model disassembly device for plastic roller processing, which has a chamfered edge on the outer ring of the injection molding itself and can cool it down. It is also convenient to disassemble, solving the problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention proposes the following technical solution: a mold disassembly device for plastic roller processing, specifically comprising: a frame body, a screw assembly, an upper buckle mold, a vertical screw and a drive motor;

[0007] A lower mold is provided at the inner bottom of the frame body, and side molds are provided on both sides of the lower mold, and both ends of the side molds are respectively installed on the screw assembly;

[0008] There are two groups of screw assemblies, and the screw assemblies respectively include a forward screw, a connecting shaft and a reverse screw. One end of the forward screw and the reverse screw are respectively fixedly connected to the connecting shaft, and the other ends of the forward screw and the reverse screw are respectively optical axis structures and rotated and inserted into the frame body;

[0009] The two vertical ends of the inner side of the frame body are respectively provided with vertical baffles, and the middle of the inner top of the frame body is also connected to a limit frame. A hopper is also installed on the top of the frame body, and a hose is connected to the bottom of the hopper, and the other end of the hose is connected to the vertical pipe on the upper buckle mold;

[0010] The top of the upper buckle mold is connected to an external connecting frame, and the two ends of the external connecting frame are respectively slidably mounted in the vertical baffle. The two ends of the external connecting frame are respectively provided with threaded holes, and are connected to the vertical screw rod through threaded engagement through the threaded holes. The bottom end of the vertical screw rod is an optical axis structure, and is vertically rotated and inserted into the frame body, and a drive motor is also installed at the bottom end of the frame body.

[0011] Optionally, a limit plate and an external connecting plate are respectively provided on both sides of the side mold, and a threaded barrel is fixedly embedded on the external connecting plate, and the threaded barrels on one group of side molds are respectively engaged with the threads on the forward screw, and the threaded barrels on the other group of side molds are respectively engaged with the threads on the reverse screw.

[0012] Optionally, an upper clamping groove is provided at the upper end of the inner arc side of the side mold, and an arc-shaped clamping edge is also provided at the lower end of the inner arc side of the side mold.

[0013] Optionally, an arc-shaped clamping ring A is provided at the outer circular edge of the bottom side of the inner hole of the lower mold, an arc-shaped clamping ring B is provided on the inner side of the upper buckle mold, and an arc-shaped clamping ring C is provided at the middle top side end of the upper buckle mold. When the two sets of side molds are fitted together, the arc-shaped clamping edges on them are connected to form a clamping ring, and have the same structure as the arc-shaped clamping ring B, and the arc-shaped clamping ring C has the same structure as the arc-shaped clamping ring A.

[0014] Optionally, a touch switch is provided in the middle of the top of the limit frame, and the touch switch is electrically connected to the drive motor. When the upper buckle mold moves upward, the outer connecting frame contacts the touch switch, causing the touch switch to operate and the drive motor to stop working.

[0015] Optionally, a transmission shaft is rotatably mounted on the bottom end of the frame body, one end of the transmission shaft is mounted with a bevel gear B, and the other end of the transmission shaft is respectively connected to the optical axis ends of the two sets of forward screws.

[0020] In addition, by setting up an injection mold consisting of an upper button mold, two sets of side molds and a lower mold, it is convenient for the raw materials in the hopper to flow into the injection mold along the hose and then be injection-molded into a plastic roller. It is also convenient to drive the vertical screw and the screw assembly by the driving motor, so that the upper button mold is lifted upward and the two sets of side molds are moved to both sides respectively. By utilizing the transmission ratio between the bevel gear A and the bevel gear B, the height of the upper button mold lifted upward is twice the outward movement distance of a set of side molds, thereby facilitating the removal of the plastic roller after injection molding.

[0021] In addition, by setting up a cooling fan, it is convenient to blow air to cool the plastic roller after injection molding to avoid burns caused by excessive temperature of the plastic roller. A filter is also set at the air inlet end of the cooling fan to filter the air entering the cooling fan to prevent excessive dust from blowing onto the roller.

[0022] In addition, by setting the arc clamp ring A, arc clamp ring B, arc clamp ring C and arc clamp edge, when the plastic roller is injection molded, the edge of the outer ring of the injection molded roller can be chamfered, and there is no need for further chamfering processing, which saves raw materials and processing time.

One end of the forward screw 201 and the reverse screw 203 are respectively fixedly connected to the connecting shaft 202, and the other ends of the forward screw 201 and the reverse screw 203 are optical axis structures and are rotatably inserted into the frame body 1.

[0051] Furthermore, according to an embodiment of the present invention, Figure 2 and Figure 11 As shown, a limiting plate 1021 and an outer connecting plate are respectively provided on both sides of the side mold 102, and a threaded barrel 1022 is fixedly embedded on the outer connecting plate. The threaded barrels 1022 on one set of side molds 2 are respectively engaged with the threads on the forward screw 201, and the threaded barrels 1022 on the other set of side molds 2 are respectively engaged with the threads on the reverse screw 203, so that the side mold 102 can be driven by the screw assembly 2 to slide on the screw assembly 2, so that the injected plastic roller can be leaked out;

[0052] The two vertical ends of the inner side of the frame body 1 are respectively provided with vertical baffles 103, and the middle of the inner top of the frame body 1 is also connected to a limit frame 104.

The bottom end of the vertical screw rod 4 is an optical axis structure and is vertically rotated and inserted into the frame body 1. The bottom end of the frame body 1 is also equipped with a drive motor 6; the bottom end of the frame body 1 is also rotatably equipped with a transmission shaft 5, and the transmission shaft 5 is A bevel gear B501 is installed at one end, and the other end of the transmission shaft 5 is also connected to the optical axis ends of the two sets of forward screws 201 respectively. The optical axis ends of the bottom ends of the vertical screws 4 are respectively connected to the motor shafts of the drive motors 6. A bevel gear A401 is also fixedly installed on the optical axis ends of one set of vertical screws 4. The bevel gear A401 is meshed with the bevel gear B501, and the transmission ratio of the bevel gear A401 to the bevel gear B501 is 2:1. After the injection molding is completed, the bevel gear A401 is rotated by the control pin. The driving motor 6 is in motion, and drives the two sets of vertical screw rods 4 to rotate respectively. Through the meshing action of the threads on the vertical screw rods 4 and the threaded holes 3011 at both ends of the outer connecting frame 301, the outer connecting frame 301 drives the upper buckle mold 3 to move upward. At the same time, the lower end of one set of vertical screw rods 4 also meshes with the bevel gear A401 and the bevel gear B501, driving the transmission shaft 5 to rotate, thereby driving the two sets of forward screw rods 201 to rotate, and making the two sets of reverse screw rods 203 rotate synchronously, and through a The threaded barrel 1022 on one set of side molds 102 is threadedly engaged with the forward screw 201, and the threaded barrel 1022 on the other set of side molds 102 is threadedly engaged with the reverse screw 203, so that the two sets of side molds 102 move outward respectively, and the injection-molded plastic roller leaks out.

When the plastic roller is injection molded, the edge of the outer ring of the injection molded roller can be chamfered, and there is no need for re-chamfering, saving raw materials and processing time.

[0055] Furthermore, according to an embodiment of the present invention, Figure 5 and Figure 8As shown, a touch switch 1041 is also provided in the middle of the top of the limit frame 104, and the touch switch 1041 is electrically connected to the drive motor 6.

An insertion frame 7011 is provided at the rear end of the outer protective frame 701, and a filter 702 is inserted in the insertion frame 7011. A handle structure is provided on the top of the filter 702. The heat dissipation fan 7 is used for blowing air and cooling. After the injection molding of the plastic roller is completed, the heat dissipation fan 7 can be used for blowing air and cooling. The air intake of the heat dissipation fan 7 is also filtered by the filter 702 to prevent excessive dust from being blown onto the roller, so that the plastic roller can be quickly taken out.

[0057] Specific usage and function of this embodiment: In the present invention, the raw materials for injection molding are put into the hopper 105, and the raw materials flow along the bottom of the hopper 105 and the hose 1051 into the plastic roller injection mold composed of the upper buckle mold 3, two sets of side molds 102 and the lower mold 101, thereby forming a plastic roller, and by controlling the operation of the drive motor 6 and the heat dissipation fan 7, the two sets of vertical screws 4 are driven to rotate respectively, and the threads on the vertical screws 4 are engaged with the threaded holes 3011 at both ends of the outer connecting frame 301, so that the outer connecting frame 301 drives the upper buckle mold 3 to move upward, and at the same time, the lower end of one set of vertical screws 4 is also engaged with the bevel gear A401 and the bevel gear B501, driving the transmission shaft 5 to rotate, thereby driving the two sets of forward screws 201 to rotate, and making the two sets of reverse screws 203 follow the rotation synchronously, and through a set of side molds 1 The threaded barrel 1022 on 02 is threadedly engaged with the forward screw 201, and the threaded barrel 1022 on the other set of side molds 102 is threadedly engaged with the reverse screw 203, so that the two sets of side molds 102 move outward respectively, and the injection-molded plastic roller leaks out. Since the transmission ratio of the bevel gear A401 and the bevel gear B501 is 2:1, the height to which the upper buckle mold 3 is lifted upward is twice the outward movement distance of a set of side molds 102, which makes it more convenient to remove the plastic roller. When the outer frame 301 contacts the touch switch 1041, the touch switch 1041 is activated, and the drive motor 6 stops working. The cooling fan 7 is also used for blowing air to cool down. By setting a filter 702 at the air inlet end of the cooling fan 7, the air inlet of the cooling fan 7 can be filtered to prevent excessive dust from being blown onto the roller, so that the plastic roller can be quickly removed.
