Description

Technical Field

[0001] The utility model relates to a mould, in particular to a mould which prevents products from bouncing off a latent gate. Background Art

[0002] In order to realize automated production, multi-cavity molds often use latent gates. When the latent gates deform during the ejection process, elastic force will be generated, which will cause the products to fly around. The flying products will come into contact with the lubrication parts of the injection molding machine and produce oil stains, affecting the quality of the products. Utility Model Content

[0012] A mold to prevent a latent gate from bouncing off a product, comprising a bottom plate 1 and a male mold plate 9 connected together by a guide rod 12, a male mold pad 10 is provided below the male mold plate 9, two square irons 5 are provided between the male mold pad 10 and the bottom plate 1, a lower ejector plate 6 and an upper ejector plate 7 are installed between the two square irons 5, the lower ejector plate 6 is arranged close to the bottom plate 1, the upper ejector plate 7 is located on the upper part of the lower ejector plate 6, an ejector 3 is provided on the upper ejector plate 7, the ejector 3 passes through the male mold pad 10 and extends into the male mold plate 9, and the lower ejector plate 6 is provided with an ejector pin 3. A delay needle 4 is installed on the ejector plate 6, and an ejector 3, a first sprue ejector 2 and a third sprue ejector 33 are installed on the upper ejector plate 7. A second sprue ejector 8 is provided between the male mold plate 9 and the male mold pad 10. A first spring 11 is sleeved on one end of the second sprue ejector 8 located in the male mold pad 10. A reset rod 13 passes through the upper ejector plate 7, the male mold pad 10 and the male mold plate 9. A second spring 14 is sleeved on the outside of the reset rod 13. The second spring 14 presses against the upper ejector plate 7 and the male mold pad 10.

[0013] The ejector pin 3, the first ejector pin 2 and the third ejector pin 33 are mounted on the upper ejector plate 7. The second ejector pin 8 is mounted between the male mold plate 9 and the male mold pad 10. The positions of the second ejector pin 8 and the third ejector pin 33 correspond. The second ejector pin 8 is ejected by the third ejector pin 33 and is reset by the compression of the first spring 11. The delay pin 4 is mounted on the lower ejector plate 6.

[0014] like Figure 1 and Figure 2 As shown, the mold design of the utility model has an ejector pin 3 and a delay pin 4, a first sprue ejector pin 2 and a second sprue ejector pin 8, which are reset by a second spring 14, and the second sprue ejector pin 8 runs through the male mold plate 9 and the male mold pad 10, and is reset independently by a first spring 11. Through two ejections, under the action of the delay pin 4, the product is first ejected completely out of the mold, and after the delay stroke is over, the first sprue ejector pin 2 and the ejector pin 3 are synchronously ejected together to form a product flow channel. After the implementation of this application, the problem of products flying around during the ejection process is solved, and oil stains caused by the contact between the product and the lubrication parts of the injection molding machine are avoided, thereby improving product quality.

[0015] During ejection, under the action of the ejector rod, the lower ejector plate 6 and the upper ejector plate 7 drive the ejector 3 and the reset rod 13 to be ejected together. Under the action of the delay needle 4, the first sprue ejector 2 and the second sprue ejector 8 do not move. After being ejected a certain distance, the first sprue ejector 2 and the second sprue ejector 8 are ejected together again. When the mold is closed, the lower ejector plate 6 and the upper ejector plate 7 are compressed by the second spring 14 and the first spring 11, and the ejector 3 returns to its original position.

[0016] The lower ejector plate 6 and the upper ejector plate 7 are arranged in parallel.

[0017] The two square irons 5 are arranged in parallel, and a space for installing a lower ejector plate 6 and an upper ejector plate 7 is provided between the two square irons 5 .

[0018] An ejector guide column 15 is provided between the lower ejector plate 6 and the upper ejector plate 7 .
