DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] For example, see Figure 1-5, an injection molding machine with an adjustable injection molding head, comprising a moving seat 1, an electric push rod 2 is arranged on the top of the moving seat 1, an output end of the electric push rod 2 is fixedly connected to a carrying plate 3, an injection molding cylinder 4 is fixedly connected to the top of the carrying plate 3, a pump body 5 is arranged on the left side of the injection molding cylinder 4, a heating bin 6 is fixedly connected to the top of the heating bin 6, a feed pipe 7 is passed through and fixedly connected to the top of the heating bin 6, a discharge pipe 8 is passed through and fixedly connected to the right side of the heating bin 6, an end of the discharge pipe 8 away from the heating bin 6 is passed through and fixedly connected to the injection molding cylinder 4, a heater 9 is arranged on the left side of the heating bin 6, an injection molding pipe 10 is passed through and fixedly connected to the right side of the injection molding cylinder 4, and an injection molding head adjustment device is arranged on the right side of the injection molding cylinder 4 The speed regulating mechanism 11 and the decelerating mechanism 12 are provided. The injection molding head regulating mechanism 11 comprises a sliding plate 111 and a side plate 1113. The sliding plate 111 is slidably connected to the right side of the injection molding cylinder 4. The left side of the sliding plate 111 is fixedly connected with a telescopic cylinder 112. The inside of the telescopic cylinder 112 is slidably connected with a telescopic rod 113. The end of the telescopic rod 113 away from the telescopic cylinder 112 is fixedly connected with a connecting block 115. A telescopic spring 114 is sleeved on the surface of the telescopic rod 113. The inner side of the connecting block 115 is fixedly connected with a connecting plate 116. Two connecting tubes 117 are penetrated and fixedly connected to the right side of the connecting plate 116. The ends of the two connecting tubes 117 away from the injection molding cylinder 4 are respectively penetrated and fixedly connected. An injection molding head A118 and an injection molding head B119 are connected. The outer diameter of the connecting tube 117 is the same as the inner diameter of the injection molding tube 10. The caliber of the injection molding head A118 is larger than the caliber of the injection molding head B119. The connecting tube 117 can be inserted into the injection molding tube 10. Injection molding heads A118 and injection molding heads B119 with different calibers can be selected according to actual conditions. A groove 1110 is opened on the side of the connecting block 115. The interior of the groove 1110 is slidably connected with an arc block 1112 through a compression spring 1111. The depth of the groove 1110 is greater than the length of the arc block 1112, and the arc surface of the arc block 1112 faces the injection molding tube 4. The arc block 1112 can be completely retracted into the groove 111 0, the arc surface of the arc block 1112 will move into the groove 1110 when being squeezed, the side plate 1113 is fixedly connected to the right side of the injection molding cylinder 4, and two slots 1114 are provided on the surface of the side plate 1113. The arc block 1112 is initially in the slot 1114 near the top of the side plate 1113, and the telescopic spring 114 is initially in a taut state. The arc block 1112 is stuck in the slot 1114 so that the connecting pipe 117 cannot be separated from the injection molding tube 10. When the arc block 1112 leaves the slot 1114, the telescopic spring 114 rebounds and drives the connecting block 115 and the connecting plate 116 to move rightward, thereby driving the connecting pipe 117 to separate from the injection molding tube 10.

[0022] When in use, the injection molding material is put into the heating bin 6 through the feed pipe 7, the heater 9 is turned on for heating, and then the injection molding material enters the injection cylinder 4 through the discharge pipe 8, and the pump body 5 is turned on to allow the injection molding material to be ejected from the injection molding tube 10 through the injection molding head B119 for injection molding. The electric push rod 2 can be turned on to drive the carrier plate 3 to rise or fall to adjust the height. When the injection molding head B119 needs to be replaced, the arc blocks 1112 at both ends are squeezed with a tool to disengage the slot 1114 and retract into the groove 1110. At this time, the telescopic spring 114 rebounds and drives the connecting block 115 and the connecting plate 116 to move to the right, thereby driving the connecting tube 117 of the injection molding head B119 to separate from the injection molding tube 10. At this time, the connecting plate is pushed 116 moves downward so that the connecting tube 117 of the injection molding head A118 is aligned with the injection molding tube 10 and inserted. At the beginning, the arc surface of the arc block 1112 is squeezed by the side plate 1113 and retracts into the groove 1110, and the compression spring 1111 is tightened. Then, when the groove 1110 fits with the slot 1114 at the bottom of the side plate 1113, the compression spring 1111 rebounds and drives the arc block 1112 to be stuck in the slot 1114 at the bottom of the side plate 1113. At this time, the arc block 1112 is stuck in the slot 1114 at the bottom of the side plate 1113, so that the connecting tube 117 of the injection molding head A118 cannot be separated from the injection molding tube 10, and the injection molding is performed by the injection molding head A118 to complete the replacement to adapt to different molds.

[0023] For example 2, please refer to Figure 1-6 On the basis of the first embodiment, the deceleration mechanism 12 includes a deceleration block 121 and a collision rod 122. The deceleration block 121 is fixedly connected to the right side of the injection cylinder 4. The collision rod 122 is hingedly connected to the sliding plate 111 through a hinge block 123. The length of the collision rod 122 is greater than the distance from the sliding plate 111 to the deceleration block 121. The deceleration block 121 is made of rubber. When the sliding plate 111 moves, it will drive the collision rod 122 to contact the deceleration block 121. When the collision rod 122 is squeezed with the rubber deceleration block 121, resistance will be generated.

[0024] During use, based on Example 1, when the connecting tube 117 of the injection head B119 is separated from the injection tube 10, the connecting plate 116 will move downward due to gravity. The downward movement of the connecting plate 116 drives the sliding plate 111 to move downward. When the sliding plate 111 moves downward, it drives the collision rod 122 and the deceleration block 121 to squeeze and generate resistance, thereby preventing the connecting plate 116 from oscillating due to the excessive speed when moving downward due to gravity. When the connecting plate 116 moves upward, the collision rod 122 contacts the deceleration block 121 and deflects, which will not generate too much resistance to make it difficult to lift the connecting plate 116.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
