Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a mold. Background Art

[0002] In the production of plastic products, molds are required to form plastics. Some products have a Boss column structure (a Boss column structure is a protruding column with holes). The ejection mechanism of the mold adopts a sleeve structure. The top plate is set above the fixed plate. The sleeve is connected to the top plate, and the ejector pin is connected to the fixed plate. The ejector pin also extends through the sleeve toward the product to form a Boss column structure for the product. During the demolding process, an external force pushes the top plate to drive the sleeve to move relative to the ejector pin, so that the sleeve ejects the product. Usually, a KO hole (i.e., ejector pin hole) is opened on the fixed plate to facilitate the external ejector pin to push the top plate to drive the sleeve to move. When the Boss column structure of the product coincides with the KO hole, the ejector pin will interfere with the KO hole, making it impossible to install the ejector pin, resulting in the problem that the mold is not convenient for producing such products.

[0068] The present application discloses a mold including: a lower mold, a fixing member, a sleeve member, an ejector pin and an ejector member. A first space for accommodating a product is provided on one side of the lower mold along a first direction. The fixing member is located on a side of the lower mold away from the first space, the fixing member is fixedly connected to the lower mold, a second space is provided between the lower mold and the fixing member, and a KO hole connected to the second space is provided on the fixing member along the first direction. The sleeve member has a connecting portion and a sleeve portion opposite to each other along the first direction, the sleeve portion is penetrated in the lower mold along the first direction, the connecting portion is located on a side of the sleeve portion facing the fixing member, and a third space is provided on the connecting portion along the second direction. The ejector pin has a first part and a second part opposite to each other along the first direction, a part of the first part is located in the sleeve portion and the first space, a part of the second part is located in the third space, the second part is connected to the lower mold, and the second part is configured to move relative to the sleeve member along the first direction in the third space. The push piece is movably arranged in the second space, and is connected to a side of the connection part away from the sleeve part. The push piece is configured to move toward the lower mold part along the first direction under the external force passing through the KO hole, and the sleeve part moves from the fixed part to the lower mold part under the action of the push piece, and the sleeve part moves into the first space and acts on the product in the first space. The first direction and the second direction are perpendicular.

[0069] In the mold of the above embodiment, the sleeve member avoids the ejector pin through the second space, so that the ejector pin is connected to the lower mold member, reducing the risk of interference between the ejector pin and the KO hole on the fixing member, thereby achieving the purpose of the mold producing products in which the Boss column structure and the KO hole overlap.

[0070] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0071] See also Figure 1 and Figure 2 A mold 10 is provided, including a lower mold 11 and an upper mold 18 which are arranged relatively to each other along a first direction X. A top is arranged on a side of the lower mold 11 facing the upper mold 18, and a first space 110 is arranged on the top. When producing a plastic product 20, an external force drives the upper mold 18 to move close to the lower mold 11 and cover the first space 110, so that the first space 110 forms a closed space, and the glue is injected into the first space 110 through the glue injection port on the upper mold 18, thereby achieving the purpose of injection molding the plastic product 20 by the mold 10.

[0072] In some embodiments, see Figure 2 and Figure 3The mold 10 further includes a fixing member 12, a sleeve member 13, an ejector pin 14 and an ejector member 15. The fixing member 12 is located on a side of the lower mold 11 away from the top, and the fixing member 12 is fixedly connected to the lower mold 11. A second space 120 is provided between the lower mold 11 and the fixing member 12. The fixing member 12 is provided with a KO hole 121 communicating with the second space 120 along the first direction X. The sleeve member 13 has a connecting portion 131 and a sleeve portion 132 opposite to each other along the first direction X. The sleeve portion 132 is penetrated in the lower mold 11 along the first direction X. The connecting portion 131 is located on a side of the sleeve portion 132 facing the fixing member 12. A portion of the connecting portion 131 is provided in the second space 120. The connecting portion 131 is provided with a third space 1311 along the second direction Y. The ejector pin 14 has a first portion 141 and a second portion 142 that are opposite to each other along the first direction X. Part of the first portion 141 is located in the sleeve portion 132 and the first space 110, and the second portion 142 is located in the third space 1311. The second portion 142 is fixedly connected to the lower mold 11. The ejector member 15 is movably disposed in the second space 120, and the ejector member 15 is fixedly connected to a side of the connecting portion 131 that is away from the sleeve portion 132. In the first direction X, the KO hole 121 at least partially overlaps with the ejector pin 14 and the sleeve portion 132, respectively. The first direction X is perpendicular to the second direction Y.

[0073] After the product 20 is formed, the upper mold 18 moves away from the lower mold 11 under the action of external force and opens the first space 110. The external ejector rod passes through the KO hole 121 to act on the ejector 15 and pushes the ejector 15 to move closer to the lower mold 11 along the first direction X. The connecting portion 131 moves from the fixing member 12 to the lower mold 11 under the action of the ejector 15, and the second portion 142 moves relative to the connecting portion 131 in the second space 120. The sleeve portion 132 moves into the first space 110 driven by the connecting portion 131 and acts on the product 20 in the first space 110, so that the sleeve portion 132 ejects the product 20 from the first space 110 to the outside of the first space 110, thereby achieving the purpose of unloading the product 20. By setting the second space 120, the ejector pin 14 is connected to the lower mold part 11 and the sleeve part 13 can move relative to the ejector pin 14, avoiding interference between the ejector pin 14 and the KO hole 121 on the fixing part 12, achieving the effect of flexible arrangement of the position of the ejector pin 14, and achieving the purpose of the mold 10 producing the product 20 in which the Boss column structure and the KO hole 121 overlap.

[0074] In addition, the connection with the push member 15 through the connection portion 131 helps to shorten the length of the sleeve portion 132. Specifically, it is found through measurement that the connection with the push member 15 through the connection portion 131 can reduce the length of the sleeve portion 132 by 50%-60% compared with the direct connection of the sleeve portion 132 with the push member 15, which helps to reduce the difficulty of processing the sleeve member 13.

[0075] In some embodiments, part of the connection portion 131 is inserted into the lower mold 11, so that when the push member 15 pushes the connection portion 131 to drive the sleeve portion 132 to move toward the first space 110, the risk of interference between the connection portion 131 and the lower mold 11 is reduced. At the same time, by partially embedding the connection portion 131 into the lower mold 11, the distance between the lower mold 11 and the push member 15 can be reduced, which helps to reduce the height of the first space 110 in the vertical direction.

[0076] In some embodiments, the third space 1311 penetrates the connecting portion 131 along the second direction Y, or is located at a side of the connecting portion 131 facing the second direction Y.

[0077] In some embodiments, the upper mold 18, the lower mold 11, the fixing member 12 and the pushing member 15 are all plate-shaped or block-shaped components.

[0078] In some embodiments, see Figure 2 and Figure 3 The mold 10 further includes a first connecting member 16, which extends along the second direction Y, a portion of which is fixedly connected to the lower mold 11, and another portion of which is inserted into the third space 1311 along the second direction Y and fixedly connected to the second portion 142. The first connecting member 16 is respectively connected to the lower mold 11 and the second portion 142, thereby achieving the purpose of fixed connection between the ejector pin 14 and the lower mold 11.

[0079] In some embodiments, the first connector 16 is located in the second space 120, and part of the first connector 16 is connected to the bottom of the lower mold 11. By arranging the first connector 16 in the second space 120, the first connector 16 and the lower mold 11 are connected in a larger space, thereby achieving the purpose of improving the installation efficiency of the first connector 16. In addition, by accommodating the first connector 16 of a larger size in the second space 120, it is helpful to improve the strength of the first connector 16, thereby improving the stability of the connection between the ejector pin 14 and the lower mold 11.

[0080] In some embodiments, the connecting portion 131 and the sleeve portion 132 are detachably connected, so that it is convenient to replace the sleeve portions 132 of different lengths according to different products 20, so as to achieve the purpose that the sleeve portion 132 can smoothly push products 20 of different sizes out of the first space 110.

[0081] In some embodiments, see Figure 4The sleeve member 13 further includes a protrusion 133, which is located on the side of the sleeve portion 132 facing the connecting portion 131. The connecting portion 131 is provided with a through slot 1312 along the second direction Y on the side of the sleeve portion 132. The through slot 1312 includes a wide portion 13121 and a narrow portion 13122. The wide portion 13121 is located on the side of the narrow portion 13122 facing the fixing member 12. Specifically, the through slot 1312 is a T-shaped slot, the sleeve portion 132 passes through the narrow portion 13122, and the protrusion 133 is embedded in the wide portion 13121, so that the sleeve portion 132 and the connecting portion 131 are detachably connected.

[0082] In other embodiments, the through slot 1312 is a dovetail slot.

[0083] In other embodiments, a threaded hole (not shown) is provided on the side of the connecting portion 131 facing the sleeve portion 132, the threaded hole is connected to the second space 120, the sleeve portion 132 is inserted into the threaded hole and is threadedly connected to the connecting portion 131, thereby achieving the purpose of detachable connection between the sleeve portion 132 and the connecting portion 131.

[0084] In other embodiments, the connecting portion 131 and the sleeve portion 132 are integrally provided.

[0085] In some embodiments, see Figure 5 The lower mold 11 includes a detachably connected mold body 111 and a lower mold core 112, the lower mold core 112 is located on a side of the mold body 111 away from the fixing member 12 along the first direction X, a pit 1121 is provided on the side of the lower mold core 112 away from the fixing member 12 along the first direction X, and a groove 1122 is provided through the side of the lower mold core 112 close to the fixing member 12 along the first direction X, and the groove 1122 is connected to the pit 1121. The first space 110 includes a third portion 1101 located in the pit 1121 and a fourth portion 1102 located in the groove 1122. During operation, the first portion 141 of the ejector pin 14 is inserted into the groove 1122 so that the injection molding material forms the BOSS column structure of the product 20 in the groove 1122. After the product 20 is formed, the ejector member 15 drives the connection portion 131 to move along the first direction X, and the connection portion 131 and the sleeve portion 132 move from the groove 1122 to the pit 1121 relative to the ejector pin 14, thereby achieving the purpose of the sleeve portion 132 ejecting the product 20. The mold body 111 and the lower mold core 112 are detachably connected, so that different lower mold cores 112 can be replaced according to different products 20, thereby achieving the purpose of producing different products 20 by the mold 10.

[0086] In other embodiments, the mold body 111 and the lower mold core 112 are integrally provided.

[0087] In other embodiments, the first connecting member 16 is located in the groove 1122 (not shown), and a portion of the connecting portion 131 and a portion of the third space 1311 are inserted into the groove 1122. The connecting portion 131 moves relative to the first connecting member 16 in the groove 1122, thereby achieving the purpose of the connecting portion 131 driving the sleeve portion 132 to move relative to the ejector pin 14.

[0088] In some embodiments, see Figure 2 The mold 10 further includes at least one guide rod 19 located in the first space 110. The guide rod 19 has two opposite ends along the first direction X. One end of the guide rod 19 is connected to the fixing member 12, and the other end of the guide rod 19 passes through the ejector 15 and is connected to the lower mold member 11. When the external ejector pushes the ejector 15 to move, the guide rod 19 guides the ejector 15, so that the ejector 15 drives the sleeve member 13 to move in a directional manner. The number of the guide rods 19 is two, three or four, which helps to improve the stability of the directional movement of the ejector 15.

[0089] In some embodiments, see Figure 2 The mold 10 further includes an elastic component 17, which is disposed in the second space 120 and between the ejector 15 and the lower mold 11. When the ejector 15 drives the sleeve 13 to eject the product 20, the ejector 15 compresses the elastic component 17. After the sleeve ejects the product 20, the external force applied to the ejector 15 is canceled, and the ejector 15 is pushed to move and reset by the elastic component 17, so that the mold 10 continues to produce the next product 20, and the automation function of the mold 10 is realized.

[0090] In some embodiments, see Figure 2 The elastic component 17 includes a plurality of compression springs 171, which are distributed in an array, and each compression spring 171 is in contact with the push member 15 and the lower mold 11. The plurality of compression springs 171 can achieve the effect of uniformly acting on the push member 15, which helps to improve the speed and accuracy of the elastic component 17 pushing the push member 15 to move.

[0091] In some embodiments, see Figure 2 A compression spring 171 is sleeved on a guide rod 19, which helps to prevent the compression spring 171 from deflecting during compression, and at the same time can improve the space utilization of the second space 120, making the structure of the mold 10 more compact.

[0092] In other embodiments, the elastic component 17 is a high temperature resistant elastic member, such as high temperature resistant silicone rubber.

[0093] In some embodiments, see Figure 2The mold 10 also includes two second connecting members 101 arranged opposite to each other in a direction perpendicular to the first direction X. The two second connecting members 101 are respectively connected to the fixing member 12 and the lower mold member 11. The second space 120 is located between the two second connecting members 101. Each second connecting member 101 is respectively connected to the fixing member 12 and the lower mold member 11, which helps to improve the stability of the connection between the fixing member 12 and the lower mold member 11. At the same time, the two second connecting members 101 are relatively arranged on both sides of the second space 120, so that the second space 120 forms a semi-enclosed space, thereby achieving the purpose of shielding the components in the second space 120 by the connecting members.

[0094] In some embodiments, the number of the second connecting members 101 is four (not shown), the four second connecting members 101 are connected end to end to form a ring shape, and the second space 120 is disposed in the four second connecting members 101 in the ring shape.

[0095] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
