Description

Technical Field

[0001] The utility model relates to the technical field of electric pre-plasticization, in particular to an electric pre-plasticization wiring protection structure. Background Art

[0002] The electric pre-plasticizing device includes a machine body and an injection device arranged on the machine body. The injection device includes a sliding seat movably arranged on the machine body, a barrel mounting seat fixedly arranged on the sliding seat, and an extruding component movably arranged on the sliding seat and capable of moving closer to or away from the barrel mounting seat. A motor is fixedly arranged on the extruding component to provide power for the injection device, and a wire inlet is arranged on the motor.

[0003] A Chinese patent with application number 202021462869.5 discloses an electric pre-plasticizing device of a hydraulic injection molding machine, comprising a fuselage; an injection device, the injection device is arranged on the upper side of the fuselage, and an injection protective cover is arranged on the outside of the injection device; a tank chain, the tank chain is arranged on the outside of the injection protective cover; an electric pre-plasticizing motor, and an inlet is arranged on the electric pre-plasticizing motor; an electric wire is arranged on the fuselage to pass through the tank chain and connect with the inlet, the tank chain is U-shaped as a whole, and the wire is arranged parallel to the injection protective cover.

[0004] In actual application, in order to adapt to different environments or working conditions, the motor model of the electric pre-plasticizing machine will be replaced or the installation position of the motor will be changed. The above changes will cause the position of the motor wire inlet to change, so that the exposed part of the wire passing through the tank chain and connected to the wire inlet is no longer parallel to the protective cover, and may even contact the protective cover or the injection device, resulting in the wire easily interfering with the injection device during the entire movement of the injection device and the movement and injection of the extrusion component. In addition, the exposed part of the wire is relatively long, and it will shake when the injection device or the extrusion component moves, further increasing the probability of interference with the injection device and reducing the safety of the electric pre-plasticizing process. Utility Model Content

[0005] The utility model provides an electric pre-plastic wiring protection structure to solve the problem that the injection device in the prior art is easy to interfere with the exposed part of the wire when moving, thereby reducing the safety.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] An electric pre-plasticizing wiring protection structure comprises a machine body and a sliding seat movable on the machine body, a barrel mounting seat and an extruding component which can be close to or away from the barrel mounting seat are fixed on the sliding seat, a motor is fixed on the extruding component, a protective cover for shielding the extruding component is arranged on the sliding seat, a first flexible protective part for wiring is arranged between the machine body and the protective cover, a second flexible protective part which is fixed to both ends and is used for wiring is arranged between the protective cover and the extruding component, the two ends of the first flexible protective part or the two ends of the second flexible protective part are respectively arranged in parallel and facing each other vertically, and with the movement of the sliding seat or the extruding component, the two ends of the first flexible protective part or the two ends of the second flexible protective part are respectively translated relatively along the moving direction of the sliding seat and there is always a semicircular corner between the two ends.

[0008] By adopting the above scheme, the wires pass through the first flexible protective part and the second flexible protective part in sequence and are connected to the wire inlet of the motor. Since the first flexible protective part is located outside the protective cover and will not interfere with the sliding seat when the sliding seat moves, the wires located inside the first flexible protective part will not interfere with the sliding seat; the second flexible protective part is arranged inside the protective cover and will not interfere with the extrusion component when the extrusion component moves, so the wires located inside the second flexible protective part will not interfere with the extrusion component; the end of the second flexible protective part away from the first flexible protective part and the motor are fixed on the extrusion component, so that the wire inlet of the motor and the end of the second flexible protective part away from the first flexible protective part are always relatively stationary. Therefore, after the wires pass through the end of the second flexible protective part, they can be directly connected to the wire inlet without interference, thereby ensuring that there will be no interference with the wires during the entire movement and retraction of the sliding seat and the injection and retraction of the extrusion component, thereby improving safety.

[0009] Preferably, the length of the first flexible protective portion is greater than or equal to the sum of the arc length of its corner and the maximum full displacement stroke of the sliding seat.

[0010] When adopting the above scheme, if the length of the first flexible protective part is too short, when the sliding seat moves to the maximum full movement stroke, the first flexible protective part will be over-pulled, causing the two ends to detach from the sliding seat or the fuselage; if the length is too long, it will not only be unsightly, but also increase the possibility of shaking, resulting in an increased possibility of interference with the sliding seat.

[0011] Preferably, the length of the second flexible protective portion is greater than or equal to the sum of the arc length of its corner and the maximum injection stroke of the extrusion component.

[0012] When adopting the above scheme, if the length of the second flexible protective part is too short, when the extrusion component moves to the maximum injection stroke, the second flexible protective part will be over-pulled, causing the two ends to detach from the extrusion component or the protective cover; if the length is too long, it will not only be unsightly, but also increase the possibility of shaking, resulting in an increased possibility of interference with the extrusion component.

[0013] Preferably, the first flexible protective part or the second flexible protective part is a tank chain or a molar tube.

[0014] By adopting the above scheme, wires can be threaded inside the tank chain and the mole tube, and both can be flexibly deformed to form a shape with two ends facing each other and parallel and with a semicircular corner. When the extrusion component or the sliding seat moves, the tank chain or the mole tube is deformed, that is, the two ends are relatively translated and the corner always exists.

[0015] Preferably, a second identification structure for selecting a corner diameter of the second flexible protective portion is provided between the extrusion component and the protective cover.

[0016] By adopting the above solution, a suitable corner diameter of the second flexible protective part is selected according to the second identification structure to avoid excessive squeezing or pulling of the second flexible protective part during deformation due to excessively large or small corner diameter, thereby extending the service life.

[0017] Preferably, the second identification structure includes a mounting plate fixed on the extrusion component and a fixing plate fixed on the inner wall of the protective cover and parallel to the mounting plate. The two ends of the second flexible protective part are respectively fixed on the mounting plate and the fixing plate. The corner diameter of the second flexible protective part is equal to the vertical distance between the mounting plate and the fixing plate.

[0018] By adopting the above solution, the vertical distance between the mounting plate and the fixing plate is fixed, and a second flexible protective part having a corner diameter equal to the vertical distance is selected.

[0019] Preferably, the protective cover is provided with an avoidance groove for one end of the first flexible protective part to pass through and then be located inside the protective cover, a fixing seat is fixedly provided on the fuselage, and both ends of the first flexible protective part are fixedly connected to the avoidance groove and the fixing seat respectively.

[0020] With the above solution, one end of the first flexible protective part is fixed in the avoidance groove, so that the end is relatively fixed with the end of the second flexible protective part fixed on the protective cover, and the part of the wire that passes through the first flexible protective part and enters the second flexible protective part will not interfere with the sliding seat or the extrusion component when it moves. At the same time, the vertical distance between the avoidance groove and the fixed seat is fixed, and the first flexible protective part with a corner diameter equal to the vertical distance can be selected.

[0021] The utility model adopts the above technical scheme, which has significant technical effects: the first flexible protective part is located outside the protective cover and will not interfere with the sliding seat when the sliding seat moves, the second flexible protective part is arranged inside the protective cover and will not interfere with the extruding part when the extruding part moves, and the end of the second flexible protective part away from the first flexible protective part and the motor are fixed on the extruding part, so that the wire inlet of the motor and the end of the second flexible protective part away from the first flexible protective part are always relatively stationary. Therefore, the wires pass through the first flexible protective part and the second flexible protective part from the fuselage in turn and are connected to the wire inlet of the motor without interference, thereby improving safety.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Example

[0035] An electric pre-molded wiring protection structure, referring to Figures 1 to 10 , including a body 1 and a sliding seat 2 moving on the body 1, a barrel mounting seat 3 and a material extrusion component 4 moving on the sliding seat 2 and close to or away from the barrel mounting seat 3 are fixed on the sliding seat 2, a motor 5 is fixed on the material extrusion component 4, a wire inlet 501 is arranged on the motor 5, and a protective cover 6 for shielding the material extrusion component 4 is arranged on the sliding seat 2. The above structures are all prior arts and will not be described in detail here.

[0036] A first flexible protective part 8 for wiring is provided between the fuselage 1 and the protective cover 6. In this embodiment, the first flexible protective part 8 is a molar tube through which the wire 17 can pass. After the molar tube is bent and deformed, the two ends are parallel to each other and a convex semicircular corner 9 is formed at the bending point. A avoidance groove 12 is provided on the protective cover 6. One end of the molar tube is fixed to the fuselage 1 through a fixing seat 13. The other end of the molar tube is located in the protective cover 6 after passing through the avoidance groove 12. A first pipe joint 15 is provided in the avoidance groove 12 for fixing the molar tube. The fixing seat 13 is a flange pipe joint. After the two ends of the molar tube are fixed to the protective cover 6 and the fuselage 1 respectively, and when the sliding seat 2 is in the initial position, the molar tube still maintains a state in which the two ends are parallel to each other. When the sliding seat 2 moves, the end of the molar tube fixed on the protective cover 6 is relatively translated relative to the end fixed on the fuselage 1 along the moving direction of the sliding seat 2. In this process, the molar tube is constantly deformed and the semicircular corner 9 always exists. The vertical distance between the avoidance groove 12 and the fixed seat 13 is fixed, and the diameter of the corner 9 of the molar tube is equal to the vertical distance. The length of the molar tube is equal to the sum of the arc length of the corner 9 and the maximum full displacement stroke of the sliding seat 2.

[0037] A second flexible protective part 7 for wiring is provided between the protective cover 6 and the extrusion component 4. In this embodiment, the second flexible protective part 7 is a tank chain through which the wire 17 can pass. After the tank chain is bent and deformed, the two ends are parallel to each other and form a convex semicircular corner 9 at the bend. A mounting plate 10 is fixed on the extrusion component 4, and a fixing plate 11 parallel to the mounting plate 10 is fixed on the inner wall of the protective cover 6. After the two ends of the tank chain are fixed on the mounting plate 10 and the fixing plate 11 respectively, and when the extrusion component 4 is in the initial position, the tank chain still maintains a state in which the two ends are parallel to each other. When the extrusion component 4 moves, the end of the tank chain fixed on the extrusion component 4 moves relatively relative to the end fixed on the protective cover 6 along the moving direction of the extrusion component 4. In this process, the tank chain is constantly deformed and the semicircular corner 9 always exists. The vertical distance between the mounting plate 10 and the fixing plate 11 is fixed. When selecting the tank chain, the diameter of the corner 9 of the tank chain can be equal to the vertical distance. The length of the tank chain is equal to the sum of the arc length of the corner 9 and the maximum injection stroke of the extrusion component 4.

[0038] The end of the mole tube away from the fuselage 1 is extended to the inside of the protective cover 6 and is provided with an extension tube 14 through which the power supply line 17 passes. The end of the extension tube 14 away from the mole tube is located on the fixing plate 11 and is directly opposite to the end of the tank chain fixed on the fixing plate 11. The end of the extension tube 14 away from the mole tube and the end of the tank chain fixed on the fixing plate 11 can be fitted or gap-fitted. The extension tube 14 is used to protect the wire 17 that passes through the mole tube but does not enter the tank chain. The fixing plate 11 is provided with a second pipe joint 16 for fixing the extension tube 14.

[0039] The electric wire 17 passes through the mole tube, the extension tube 14 and the tank chain from the fuselage 1 in sequence and is connected to the wire inlet 501 of the motor 5, thereby ensuring that during the entire movement and retraction process of the sliding seat 2 and the injection and retraction process of the extrusion component 4, there will be no interference with the electric wire 17, the mole tube, the extension tube 14 and the tank chain, thereby improving safety.

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
