Description

Technical Field

[0001] The invention relates to the technical field of injection moulds, in particular to an injection mould for a guide rail slider of a rear door glass lifter of an automobile. Background Art

[0002] The guide rail slider of the car rear door glass lifter is one of the important parts of the car. It is used to control the lifting and lowering of the car rear door glass. When producing the guide rail slider of the car rear door glass lifter, an injection mold is needed. The injection mold is a tool used for plastic injection molding. When producing the slider, the molten plastic is injected into the mold cavity in the injection mold, filling the entire mold cavity and contacting the inner wall of the mold. At the same time, the cooling system in the mold will absorb heat from the mold, so that the plastic will cool and solidify quickly. When the plastic is completely solidified, the mold will separate and push out the molded parts. The working process of the entire injection mold is repeated in a cycle to continuously produce plastic parts.

[0003] The existing injection molds are widely used, but the movement of the existing injection molds is troublesome. When moving the injection mold to the plastic raw material tank, it is necessary to use tools such as a crane to carry it. During injection molding, part of the plastic will be discharged from the exhaust hole on the injection mold. After the plastic is cooled and formed, this part of the plastic will stick to the object, so that the workers need to manually cut off this part of the plastic, resulting in low work efficiency. In addition, the pushing device on the injection mold is not provided with a buffer component, and the device is easily damaged if it is used for too long. Therefore, in view of the above problems, an injection mold for a guide rail slider of a rear door glass lifter of an automobile is proposed. Summary of the invention

The positioning component 197 can prevent the plastic from entering the inner side of the air groove 195 during injection molding. The next step is to start the plastic raw material tank, and the plastic is injected into the inner side of the injection molding groove 193 through the injection hole 194. Since the air inside the injection molding groove 193 is sucked away, the plastic can directly fill the gap between the injection molding groove 193 and the mold sealing seat 16. The setting of the sealing component 196 and the positioning component 197 can prevent the surface of the cooled and molded object from producing excess plastic, thereby improving work efficiency.

[0036] Workflow: Power on the device before use and connect the device to an external control device. First, install the fixed mold assembly 19, insert the limit block 192 at the bottom of the fixed mold plate 191 into the inner side of the limit groove 18 at the top of the support plate 17, place the clamping plate 20 on the top of the fixed mold plate 191 and insert the limit block 192 into the inner side of the limit hole 22, insert the threaded column 23 at the top of the vertical rod 25 into the inner side of the socket 21, and then tighten the clamping nut 24 on the outer side of the threaded column 23 to complete the installation of the fixed mold assembly 19. Next, install the buffer assembly 13, insert the mounting bolt 133 on one side of the buffer plate 135 into the inner side of the circular hole 132 on the circular plate 131, and screw the mounting nut 134 on the outer side of the mounting bolt 133 to complete the buffer assembly 13. After installation, the next step is to move the device to the side of the plastic raw material tank, start the electric telescopic rod 41 on the top of the storage plate 1, and the output shaft of the electric telescopic rod 41 moves to drive the connecting frame 42 and the universal wheel 43 to move. When the universal wheel 43 contacts the ground, the device begins to rise slowly, and then push the device until the device moves to the desired position, then close the electric telescopic rod 41, and let the device slowly descend, so that the mounting seat 2 fits tightly with the ground, and finally use the expansion bolt to insert it into the mounting hole 3 and drive it into the ground to complete the movement and fixation of the device. The setting of the moving component 4 makes the movement of the device more convenient, and it can be moved without the help of a crane, reducing the cost of use. When injection molding is required, connect the plastic raw material tank with the injection hole 194 on the right side of the fixed mold plate 191, and fix the shell 197. The vacuum pump 1974 at the bottom of the side plate 1 is connected to an external vacuum pump, and the movable mold plate 15 and the fixed mold plate 191 are connected to an external cooling device. The hydraulic rod 6 on the right side of the side plate 5 is started, and the output end of the hydraulic rod 6 extends to drive the orifice plate 8 and its connecting components to move until the mold sealing seat 16 is inserted into the inner side of the injection groove 193 on the left side of the fixed mold plate 191, and the right side of the movable mold plate 15 is tightly fitted with the left side of the fixed mold plate 191. Then the vacuum pump is started. At this time, the air inside the injection groove 193 pushes the sealing piston 1964 inside the air groove 195. The sealing piston 1964 moves to drive the limit rod 1962 to slide inside the fixed frame 1961, and the limit spring 1963 is compressed. The air inside the injection groove 193 passes between the sealing piston 1964 and the air groove 195. The gap enters the inner side of the shell 1971 and is discharged through the vacuum tube 1974. Then the air pump is turned off. The pressure inside the air groove 195 and the shell 1971 is greater than the pressure inside the injection groove 193. The limit spring 1963 is reset to drive the limit rod 1962 to slide inside the fixed frame 1961 until the sealing piston 1964 is tightly fitted with one end of the air groove 195. Then the micro telescopic rod 1972 is started, and the output shaft of the micro telescopic rod 1972 moves inside the sealing ring 1973 until one end of the output shaft of the micro telescopic rod 1972 is tightly fitted with one end of the limit rod 1962. The positioning component 197 can prevent the plastic from entering the inner side of the air groove 195 during injection molding. The next step is to start the plastic raw material tank, and the plastic is injected into the inner side of the injection groove 193 through the injection hole 194.Since the air inside the injection groove 193 is sucked away, the plastic can directly fill the gap between the injection groove 193 and the mold sealing seat 16. The setting of the sealing component 196 and the positioning component 197 can prevent the surface of the cooled and molded object from producing excess plastic, thereby improving work efficiency. The next step is to adjust the hydraulic rod 6 to retract its output shaft, so that the fine slide rod 10 slides inside the fixed mold assembly 19, and the orifice plate 8 and the push assembly 14 and their connecting components move until the buffer plate 135 on the first connecting rod 7 and the second connecting rod 12 contact and fit tightly. The buffer plate 135 can buffer the device and reduce the vibration caused by the contact between the first connecting rod 7 and the second connecting rod 12. At this time, the mounting plate 11 slides on the outside of the coarse slide rod 9, and the push rod 142 on one side of the fixed plate 141 slides on the inside of the movable mold plate 15 and the mold sealing seat 16 to push out the injection molded product outside the mold sealing seat 16. The return spring 143 on one side of the sealing ring 144 is compressed by force, and the injection molding and unloading of the plastic part can be completed once. The above process is repeated in a cycle to continuously produce plastic parts. ,
