Description
Technical Field
[0001] The utility model relates to an injection mold for a silencer interface of an automobile air intake pipe. Background Art
[0002] The automobile intake duct refers to the air pipe that guides the gas required for the combustion of the internal combustion engine into the machine. The intake duct must ensure sufficient flow area, avoid turns and sudden changes in cross-section, improve the smoothness of the pipe surface, etc., to reduce resistance; in addition, a muffler must be connected in series on the intake duct. The function of the muffler is to suppress the pulse of the intake air through the expansion and interference of the resonator, thereby reducing the intake noise.
[0003] In order to enable the air intake pipe and the muffler to be quickly connected and disassembled, the automobile air intake pipe and the muffler on the market are all provided with matching plastic interfaces. Since the shape of the plastic interface is relatively complex and the structures of the two openings of the plastic interface are different, one is a snap-fit structure and the other is an internal thread structure; therefore, the existing muffler interface injection mold cannot mold all the structures of the plastic interface at one time, and can only complete the preliminary molding. The remaining unmolded structure needs to be completed by arranging a secondary molding step separately. Therefore, the operation steps are relatively cumbersome, resulting in low production efficiency, and two molds need to be made, resulting in high production costs, which needs further improvement.

[0034] Working principle: The end plate 1 in the movable mold and the tail plate 6 in the fixed mold are respectively installed on the action mechanism and the body of the injection molding machine; the end plate 1 is driven to move backward by the action mechanism, and then the movable block 2 is driven to move toward the fixed block 4 until the two are assembled with each other (existing technology), so that the ends of the first molding block 8, the second molding block 9, the third molding block 10, the fourth molding block 11 and the fifth molding block 12 are in contact with the ends of the sixth molding block 13, the seventh molding block 14 and the eighth molding block 15, and at this time, the end of the first stopper 51 is in contact with the end of the second stopper 31; A left tube cavity is formed between the first arc-shaped molding surface 81 on the first molding block 8, the second arc-shaped molding surface 91 on the second molding block 9, the third arc-shaped molding surface 101 on the third molding block 10, the fourth arc-shaped molding surface 111 on the fourth molding block 11, the fifth arc-shaped molding surface 121 on the fifth molding block 12, the sixth arc-shaped molding surface 131 on the sixth molding block 13, the seventh arc-shaped molding surface 141 on the seventh molding block 14, and the eighth arc-shaped molding surface 151 on the eighth molding block 15; an upper tube opening is formed between the first arc-shaped tube opening groove 52 and the second arc-shaped tube opening groove 32.
[0035] Afterwards, the telescopic end of the positioning cylinder 202 in the composite shaping mechanism 20 is driven to extend outward to drive the driven slider 205 to move toward the lower right with the help of the positioning slider 201, until the fourth molding cavity 2051 moves to the lower left of the eighth molding block 15; at the same time, the telescopic end of the first active cylinder 165 in the first active shaping mechanism 16 is driven to extend outward to drive the conical positioning head 163 to move downward with the help of the traction rod 166, until the outer wall of the conical positioning head 163 and the inner wall of the conical positioning sleeve 162 fit each other, and then the telescopic end of the first active cylinder 165 continues to extend outward. When extending, the first active slider 161 will be pulled downward with the help of the conical positioning sleeve 162, thereby driving the conical positioning head 163 and the conical positioning sleeve 162 to continue to move downward, so that the first inner molding head 164 passes through the upper tube opening and extends into the left tube cavity; and then at the same time, the telescopic end of the second active cylinder 192 in the second active molding mechanism 19 is driven to extend outward to drive the second inner molding head 193 to move toward the upper right with the help of the second active slider 191, so that the end of the second inner molding head 193 extends into the left tube cavity and fits on the end of the first inner molding head 164.
[0036] When the moving block 2 moves backward, it will drive the positioning rod 204 in the composite shaping mechanism 20 to move backward to force the positioning slider 203 to move to the right, until the blocking block 2032 on the positioning slider 203 is inserted into the positioning notch 54; it will also drive the first driving rod 172 in the first passive shaping mechanism 17 to move backward to force the first passive slider 171 to move to the left, thereby moving the first molding cavity 1712 to the right of the first inner molding head 164 and fitting together with the upper right opening of the left tube cavity; it will also drive the second driving rod 182 in the second passive shaping mechanism 18 to move backward to force the second passive slider 181 to move toward the upper left, thereby moving the second molding cavity 1812 to the right of the end of the second inner molding head 193 and fitting together with the lower right opening of the left tube cavity, and at the same time, moving the third molding cavity 1813 to the right of the root of the second inner molding head 193 and fitting together with the fourth molding cavity 2051.
[0037] Afterwards, the molten material enters the left tube cavity, the first molding cavity 1712, the second molding cavity 1812, the third molding cavity 1813 and the fourth molding cavity 2051 through the gates provided in the end plate 1 and the moving block 2, and is wrapped around the outside of the first inner molding head 164 and the second inner molding head 193, and the muffler interface 21 is formed after cooling; then, the end plate 1 is driven forward by the action mechanism to drive the moving block 2 away from the fixed block 4, and then, the molded muffler interface 21 is ejected forward by the ejection mechanism 7 (now However, before that, the telescopic end of the positioning cylinder 202, the telescopic end of the first active cylinder 165 and the telescopic end of the second active cylinder 192 need to be driven to retract inwards so that the telescopic end of the positioning cylinder 202 can extend outwards to respectively drive the positioning slider 201, the conical positioning head 163 and the first active slider 161 to move in the opposite direction to reset, and the moving block 2 will similarly drive the positioning slider 203, the first passive slider 171 and the second passive slider 181 to move in the opposite direction to reset during the forward movement.
[0038] The left tube cavity, the first molding cavity 1712, the second molding cavity 1812, the end of the first inner molding head 164 and the end of the second inner molding head 193 cooperate with each other to form the main body 211 in the middle of the muffler interface 21; the first arc-shaped pipe mouth groove 52, the second arc-shaped pipe mouth groove 32, the arc-shaped card groove 2033 and the root of the first inner molding head 164 cooperate with each other to form the card interface 212 at the upper end of the main body 211; the fourth molding cavity 2051, the third molding cavity 1813 and the root of the second inner molding head 193 cooperate with each other to form the internal threaded opening 213 at the lower end of the main body 211; the second convex ring 33 and the first convex ring 53 respectively form the first shell 215 and the second shell 214 on the front and rear sides of the main body 211.
[0039] The utility model can simultaneously mold the entire structure of the muffler interface 21 in only one molding process, without the need to arrange a second molding process, thereby effectively simplifying the operation steps to improve production efficiency, and only one mold needs to be made, thereby effectively reducing production costs.
