DETAILED DESCRIPTION

[0025] like Figures 1-4 As shown, an in-mold cutting fabric mechanism for an automobile pillar injection molding mold includes a lower template 1, on which two protruding molding protrusions 2 are symmetrically arranged, and two in-mold cutting fabric components 3 are arranged between the two molding protrusions 2. The lower template 1 is also provided with a detachable insert structure 4 connected to the front end of the molding protrusion 2, and the lower template 1 is also provided with a large inclined ejection mechanism 5.

[0026] In the utility model, the in-mold cutting fabric component can cut the inner edge of the column product in the mold after the column is solidified and formed, without the need for post-processing, which can reduce the production process of the column;

[0027] Secondly, a removable insert structure 4 is provided on the lower template so that a spare insert can be used to replace the insert when the insert position is damaged, which can reduce the risk of damage and scrapping of the lower template. The large inclined ejection mechanism 5 can apply thrust to the vulnerable position of the product after the product is formed. The large inclined ejector can increase the contact area with the vulnerable position of the product, thereby reducing the risk of damage to the product during ejection.

[0028] Specifically, the in-mold fabric cutting assembly 3 comprises a fabric block 6 embedded within the lower mold plate 1. Cutting sections 7 are symmetrically positioned on either side of the top of the block 6, connected to the inner sidewalls of the molding protrusions 2. A lifting actuator is also located on the underside of the lower mold plate 1, connected to a cutting pin 8 at the bottom of the block 6. After the product solidifies, the lifting actuator, via the cutting pin, drives the block upward, allowing the cutting section to cut the inner edge of the column product. This eliminates the need for post-processing and reduces the number of steps in the column production process.

[0029] Those skilled in the art should understand that the lifting drive may be an oil cylinder, an air cylinder or a linear motor, etc.

[0030] Preferably, the bottom of the fabric block 6 is recessed inwardly to provide a connecting slot 9 with a T-shaped cross section, and the top of the block push rod 8 is fixedly connected to a connecting slider 10 that is inserted into the connecting slot 9. The front and rear sides of the connecting slot 9 pass through the fabric block 6. The fabric block 6 and the block push rod 8 are connected by the connecting slot 9 with a T-shaped cross section and the connecting slider 10, which can be easily disassembled.

[0031] Specifically, the removable insert structure 4 includes a front insert 11 whose bottom is embedded in the lower mold plate 1. The inner end of the top portion of the front insert 11 protruding from the lower mold plate 1 abuts against the molding protrusion 2. The front insert 11 is removably fixed to the lower mold plate 1 by a number of screws. The front insert 11 is removably fixed to the lower mold plate 1 by a number of screws, so that it can be replaced with a spare insert if damaged, reducing the risk of damage and scrapping of the lower mold plate.

[0032] Specifically, the large inclined ejection mechanism 5 includes an elongated inclined ejector block 12 positioned outside and along the length of the molding protrusion 2. Two numbered inclined ejector rods 13 are located at the bottom of the elongated inclined ejector block 12, connecting it to the ejector plate located on the underside of the lower mold plate 1. As the ejector plate moves upward, the numbered inclined ejector rods drive the elongated inclined ejector block 12 upward, exerting thrust on the product. This elongated inclined ejector block increases the contact area with the product, thereby reducing the risk of damage during ejection.

[0033] Preferably, the system further includes two guide structures corresponding to the first inclined ejector rod 13. The guide structures can limit the position of the first inclined ejector rod. The guide structures include an inclined guide rod 14, to which a guide sleeve 15 is slidably connected. The guide sleeve 15 is fixedly connected to the first inclined ejector rod 13. The guide rod 14 and the guide sleeve cooperate to limit the position of the first inclined ejector rod.

[0034] Preferably, the front side of the lower template 1 is further provided with several inclined ejector assemblies, including a front inclined ejector block 16, which is connected to the ejector plate via a second inclined ejector rod 17. When the ejector plate moves upward, the second inclined ejector rod can also drive the front inclined ejector block to move diagonally upward, thereby cooperating with the long inclined ejector block to eject the product.

[0035] The working principle of the present invention is as follows: the in-mold cutting fabric assembly can cut the inner edge of the column product in the mold after the column is solidified and formed, without the need for post-processing, which can reduce the production process of the column; secondly, the detachable insert structure 4 is provided on the lower template, which can be replaced with a spare insert when the insert position is damaged, thereby reducing the risk of damage and scrapping of the lower template; the large inclined ejector mechanism 5 can apply a thrust to the vulnerable position of the product after the product is formed. The large inclined ejector can increase the contact area with the vulnerable position of the product, thereby reducing the risk of damage to the product during ejection;

[0036] After the product is solidified, the lifting driver can drive the fabric block to move upward through the cutting push rod, so that the inner edge of the column product can be cut by the cutting part, without the need for post-processing, which can reduce the production process of the column. The fabric block 6 and the cutting push rod 8 are connected by a T-shaped connecting groove 9 and a connecting slider 10, which can be easily disassembled.

[0037] The front end insert 11 is detachably fixed to the lower template 1 by a number of screws and can be replaced with a spare insert when damaged, which can reduce the risk of damage and scrapping of the lower template. The upward movement of the top plate can drive the long inclined ejector block 12 to move obliquely upward through the No. 1 inclined ejector rod to apply thrust to the product. The long inclined ejector block can increase the contact area with the product to reduce the risk of damage to the product during ejection. The guide structure can limit the No. 1 inclined ejector rod, and the guide rod 14 and the guide sleeve can cooperate to limit the No. 1 inclined ejector rod. When the top plate moves upward, it can also drive the front inclined ejector block to move obliquely upward through the No. 2 inclined ejector rod, so that it can cooperate with the long inclined ejector block to eject the product.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0039] Although this article uses the lower template 1, forming protrusion 2, in-mold cutting fabric assembly 3, detachable insert structure 4, large inclined ejector mechanism 5, fabric cutting block 6, cutting part 7, cutting block ejector rod 8, connecting slide 9, connecting slider 10, front end insert 11, long strip inclined ejector block 12, No. 1 inclined ejector rod 13, guide rod 14, guide sleeve 15, front inclined ejector block 16, No. 2 inclined ejector rod 17, etc. more frequently, these terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
