Description

Technical Field

[0002] The demoulding mechanism for automobile plastic parts molding is an auxiliary device for automobile plastic parts molding demoulding, and is widely used in the field of demoulding mechanisms.

[0003] Under the existing technology, there is a lack of effective linkage between the ejection mechanism and the upper mold, and the ability to move synchronously with the upper mold. The existing ejection mechanism may delay ejection or eject too early during demolding. Delayed ejection will increase the adhesion time between the plastic part and the mold, further increasing the risk of mold jamming; while premature ejection may cause the plastic part to be forcibly demolded before it is fully formed, affecting its structural integrity. At the same time, when the plastic part is formed, the adhesion between it and the mold is large, and it is easy for the plastic part to get stuck on the upper mold, which will not only cause unsmooth demolding and affect production efficiency, but may also damage the plastic part and reduce product quality.

[0004] Therefore, it is necessary to provide a kind of automobile plastic parts molding demoulding mechanism to solve the above-mentioned technical problems. Utility Model Content

A molding and demoulding mechanism for automobile plastic parts comprises: a workbench 1, a molding box 2 is fixedly connected to the top of the workbench 1, a cylinder 3 is installed on the top of the molding box 2, a telescopic rod 4 is slidably connected to the bottom of the cylinder 3, a central block 5 is fixedly connected to the bottom of the telescopic rod 4, an upper mold 6 is fixedly connected to the bottom of the central block 5, an injection port 7 is provided at the top of the upper mold 6, synchronization rods 8 are fixedly connected to both sides of the central block 5, two guide holes 9 are provided at the top of the workbench 1, a lower mold 10 is fixedly connected to the top of the workbench 1, a constraint sleeve 11 is fixedly connected to the bottom of the lower mold 10, a reset plate 12 is slidably connected inside the constraint sleeve 11, two ejector rods 13 are fixedly connected to the top of the reset plate 12, an ejector plate 14 is fixedly connected to the top of the ejector rod 13, a reset spring 15 is fixedly connected to the top of the reset plate 12, and the design of the ejection mechanism moving synchronously with the upper mold 6 can greatly improve the demoulding efficiency. When the mold is opened, the ejection mechanism acts immediately without any additional waiting time, and the plastic parts are ejected quickly and accurately, effectively reducing the production cycle and improving overall production efficiency.

[0021] An air pump 16 is installed on the top of the molding box 2, and an air pipe 17 is fixedly connected to the air pump 16. A filter 18 is installed on the back of the air pump 16. A one-way valve 19 is arranged on the top of the upper mold 6, and the one-way valve 19 is fixedly connected to the air pipe 17. An air pump rod 20 is fixedly connected to the back of the central block 5, and an air pump pressing block 21 is fixedly connected to the air pump rod 20. An air pump button 22 is arranged on the inner wall of the molding box 2. A waste groove 23 is opened on the top of the workbench 1, and the molded plastic parts may get stuck in the upper mold. 6, during the upward movement of the upper mold 6, the air pump rod 20 on the central block 5 moves synchronously, so that the air pump pressing block 21 presses the air pump button 22, and transmits the signal to the control board 28 through the electrical connection. The control board 28 starts the air pump 16 for three seconds through the electrical connection, and forms air pressure between the upper mold 6 and the stuck plastic part through the air pipe 17 to extrude the plastic part. When the upper mold 6 moves downward, it will contact the air pump button 22 again. At this time, the waste debris generated after the last demoulding will be blown into the waste trough 23 on the workbench for centralized treatment.

[0022] A raw material box 24 is installed on the top of the molding box 2 , and a raw material pipe 25 is fixedly connected to the top of the raw material box 24 .

[0027] When the device is working, the cylinder 3 is started, the telescopic rod 4 moves downward, the central block 5 and the upper mold 6 move downward at the same time, until the upper mold 6 is engaged with the lower mold 10, and after injection molding through the injection port 7, demoulding begins, the telescopic rod 4 retracts, and at the same time drives the central block 5 to move upward, and the synchronization rods 8 on both sides move upward in the guide holes 9 at the same time, and after passing a distance at one end, an upward force is applied to the reset plate 12, thereby driving the ejection plate 14 on the ejection rod 13 to eject upward, and the molded plastic parts are ejected. The periphery of the ejection plate 14 is sealed to prevent plastic liquid from entering the ejection mechanism. The ejection mechanism and the upward movement of the upper mold 6 are completed synchronously, so that the ejection timing will not be advanced or delayed, and the plastic parts can be ejected quickly and accurately from the lower mold 10.

[0028] Compared with the related art, the automotive plastic parts molding and demoulding mechanism provided by the utility model has the following beneficial effects:

[0029] The design of the ejection mechanism moving synchronously with the upper mold 6 can greatly improve the demoulding efficiency.
