Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a panel bracket mold with a delayed ejection mechanism. Background Art

[0002] Injection mold is a tool used in the injection molding process. Its design and processing quality directly affect the function, appearance and precision of the molded plastic parts. Figure 1 The panel bracket product shown has multiple snap-on structures at its bottom that are far away from the bottom surface of the product. The connecting part between the snap-on structure and the bottom surface has multiple lateral reinforcing rib structures.

[0037] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0038] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0039] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element can be directly connected to the other element or an intervening element (e.g., a third element) can be present between the element and the other element.

[0040] See also Figure 1 The panel bracket product has multiple lateral reinforcing rib structures 4 that need to be injection molded at the bottom of the product. The lateral reinforcing rib structure 4 is different from the mold opening direction. Direct ejection can easily cause the lateral reinforcing rib structure to crack or deform, damaging the product.

[0041] In order to solve the above technical problems, the embodiment of the present invention provides a panel bracket mold with a delayed ejection mechanism, such as Figure 1-1 3, including:

[0042] The mold body 1 includes an upper mold assembly 101 and a lower mold assembly 102. The lower mold assembly 102 includes a lower mold core 103. The upper mold assembly 101 and the lower mold assembly 102 are combined to form a product molding cavity 104.

[0043] Multiple delayed ejection mechanism bodies 2 are arranged on the lower mold assembly 102, and each delayed ejection mechanism body 2 includes an ejection seat 201 arranged on the lower mold core 103, a delay assembly 202 arranged in the ejection seat 201, and an ejection structure 203 connected to the ejection seat 201 and arranged on the lower mold assembly 102; the delay assembly 202 includes a ejector rod structure 204 passing through the ejection seat 201 and an elastic structure 205 sleeved on the ejector rod structure 204, a side forming cavity 206 is provided on one side of the ejection seat 201, one end of the ejector rod structure 204 is a protruding end 207 protruding from the ejection seat 201, and the other end is a forming end 208 connected to the side forming cavity 206, and a vertical limit groove 105 matching the protruding end 207 is provided on one side of the lower mold core 103.

[0044] The delayed ejection mechanism body 2 is arranged on the lower mold assembly 102, and has the functions of molding and demoulding. The ejection seat 201 has a core for molding the lateral reinforcing rib structure 4 and a corresponding side molding cavity 206. The ejection seat 201 can also be provided with other molding structures of adjacent structures. The lower part of the ejection seat 201 can be adapted to a variety of ejection structures 203 for ejecting the ejection seat 201. The delay assembly 202 is arranged in the ejection seat 201, wherein the ejector rod structure 204 horizontally penetrates the ejection seat 201. Specifically, the molding of the ejector rod structure 204 The end 208 and one side of the ejector seat 201 together form a side forming cavity 206, so that after the product is formed, the forming end 208 of the ejector structure 204 abuts against the lateral reinforcing rib structure 4 of the panel bracket product, and the other end of the ejector structure 204 is a protruding end 207 protruding out of the ejector seat 201, and the protruding end 207 is placed in the vertical limit groove 105 on the side of the lower mold core 103 that matches the protruding end 207. An elastic structure 205 is sleeved on the ejector structure 204, and the elastic structure 205 can be a spring, a spring sheet or other elastic structures. The structure 205 is used to provide power for the delay component 202. When the mold is closed, the elastic force of the elastic structure 205 limits the ejector structure 204 to the required position of the ejector seat 201. At this time, the molding end 208 is in contact with the side molding cavity 206. When the mold is opened, the ejector seat 201 ejects the product under the action of the ejection structure 203. The protruding end 207 of the ejector structure 204 in the ejector seat 201 abuts against the vertical limit groove 105. As the vertical limit groove 105 is limited, it gradually slides into the ejector seat 201 and compresses the elastic structure 205, and the sliding is formed. The profile end 208 extends outward from the ejection seat 201 to apply pressure to the lateral reinforcing rib structure 4, so that the lateral reinforcing rib structure 4 is not affected by the oblique direction of the ejection structure 203 and is ejected from the mold in a vertical state. When the ejector rod structure 204 is separated from the vertical limit groove 105, the elastic force of the elastic structure 205 resets the ejector rod structure 204. At this time, the lateral reinforcing rib structure 4 begins to be ejected from the mold along with the lateral core pulling of the ejection structure 203. This mechanism realizes the staged delayed ejection of the lateral reinforcing rib structure, greatly reduces the damage and cracking of the lateral reinforcing rib structure, and improves product quality.

[0045] In some embodiments, as Figure 5-8 As shown, the top rod structure 204 includes a limiting structure 209 provided on one side of the elastic structure 205 , and the limiting structure 209 is used to limit the position of the top rod structure 204 .

[0046] Under the action of the elastic structure 205 , the limiting structure 209 is firmly in contact with the side wall, so that the forming end 208 can be stably connected with the side forming cavity 206 .

[0047] Furthermore, if Figure 7-8As shown, the limiting structure 209 includes a first limiting structure 210 abutting against the elastic structure 205 and a second limiting structure 211 arranged on one side of the first limiting structure 210 .

[0048] Specifically, the first limiting structure 210 can be a circular, square or other structure that can support the elastic structure 205. It is preferably a circular limiting block of a size similar to the elastic structure 205, so that the ejector structure 204 can slide in the ejection seat 201 while the elastic structure 205 does not move. The second limiting structure 211 can be a protruding block structure protruding from the first limiting structure 210, or it can be a notch on the first limiting structure 210. The second limiting structure 211 prevents the ejector structure 204 from rotating and slipping.

[0049] Furthermore, if Figure 5-8 As shown, the ejection seat 201 is provided with a through slot 212, which includes a first slide slot 213 matching the ejector structure 204, a second slide slot 214 arranged on one side of the first slide slot 213 matching the elastic structure 205, and a third slide slot 215 arranged on one side of the second slide slot 214 matching the limiting structure 209. One end of the elastic structure 205 abuts against one end of the second slide slot 214, and the other end abuts against the limiting structure 209.

[0050] The delay component 202 slides in the through slot 212, and the top rod structure 204 runs through the entire through slot 212. The first slide slot 213 matches the top rod structure 204, which is convenient for limiting other structures inside the delay component 202 and preventing them from falling off. The elastic structure 205 is sleeved on the top rod structure 204 and compressed and released in the second slide slot 214. The limiting structure 209 slides in the third slide slot 215 under the influence of the elastic force of the elastic structure 205. Specifically, one end of the elastic structure 205 abuts against the side wall of the second slide slot 214, and the other end abuts against the side wall of the second slide slot 214. One end is in contact with the limiting structure 209. When the mold is closed, the limiting structure 209 is affected by the elastic force of the elastic structure 205 and is in contact with the side wall of the third slide groove 215, which is convenient for positioning the position of the molding part. During the mold opening, the protruding end 207 is driven by the vertical limit groove 105 to slide into the inside of the ejector structure 204. At this time, the limiting structure 209 also presses against the elastic structure 205, and at this time the second limiting structure 211 slides in the third slide groove 215, and the third slide groove 215 limits the overall movement of the ejector structure 204.

[0051] In some embodiments, as Figure 4 -6 (b), the ejector seat 201 is provided with a first inclined surface 216 on the side close to the protruding end 207, which gradually moves away from the side forming cavity 206 from bottom to top. The lower mold core 103 is provided with a second inclined surface 106 that matches the first inclined surface 216. The vertical limit groove 105 is provided on the second inclined surface 106, and the side of the vertical limit groove 105 opposite to the ejector seat 201 is a vertical surface.

[0052] The first inclined surface 216 and the second inclined surface 106 slide relative to each other during mold opening and closing. The vertical limit groove 105 is provided on the second inclined surface 106. The side opposite to the ejection seat 201, that is, the side in contact with the protruding end 207, is a vertical surface. This facilitates the vertical lifting of the lateral reinforcement rib 4 along with the product without being affected by the lateral demoulding of the ejection mechanism. This delays the demoulding of the lateral reinforcement rib structure 4 and prevents it from being damaged or cracked.

[0053] Furthermore, if Figure 4 As shown in FIG6 ( b ), a boss 217 is provided on the top of the ejector seat 201 near the lifting limit groove 105 , and a groove 107 matching the boss 217 is provided on the second inclined surface 106 .

[0054] The boss 217 and the groove 107 are separated as the ejection structure 203 is ejected, and the protruding end 207 abuts and moves upward in the vertical limit groove 105, while compressing the elastic structure. When the protruding end 207 leaves the vertical limit groove 105, the elastic structure is released, and the ejector rod structure 204 is ejected accordingly. The setting of the groove 107 allows the ejector rod structure 204 to be released without damaging the lower mold core 103.

[0055] In some embodiments, as Figure 5-7 As shown, the protruding end 207 is in an arc shape.

[0056] The arc-shaped structure reduces interference during ejection and facilitates resetting of the delay component 202 .

[0057] In some embodiments, as Figure 4 、 9 -13, the ejection structure 203 includes a guide base 219 provided with a guide groove 218 mounted on the lower mold assembly 102, a slider structure 220 matching the guide base 219, a guide rod 221 connected to the slider structure 220, a guide plate 222 provided on the lower mold assembly 102 for guiding the guide rod 221, and a connecting structure 223 for connecting the guide rod 221 and the ejection seat 201.

[0058] The guide base 219 is provided with a guide groove 218, which facilitates the relative sliding of the slider structure 220 in the guide groove 218 when the mold is opened, so that the guide rod 221 lifts the ejector seat 201. The guide groove 218 can be other structures such as H-type, L-type or dovetail type. The guide block 225 is used to guide the guide rod 221 during demolding and closing.

[0059] Furthermore, if Figure 9-13, the slider structure 220 includes a slider body 224 disposed in the guide groove 218 and a guide block 225 connected to the slider body 224. The guide block 225 has a connecting groove 226 connected to the guide rod 221, and connecting protrusions 227 are provided on both sides of the guide block 225. The slider body 224 has a connecting hole 228 that cooperates with the connecting protrusion 227.

[0060] Specifically, the slider body 224 can be a matching slider arranged in the guide groove 218 on both sides of the guide base 219. The separately arranged slider bodies 224 are connected by the connecting protrusion 227 of the guide block 225 and the connecting hole 228 of the slider body 224. The guide rod 221 is inserted into the connecting groove 107 of the guide block 225. The split structure facilitates the installation and movement of the guide rod 221.

[0061] In some embodiments, as Figure 1-1 3 , the delayed ejection mechanism body 2 includes a first delayed ejection structure 108 , a second delayed ejection structure 109 , a third delayed ejection structure 110 and a fourth delayed ejection structure 111 arranged on the lower mold core 103 , and a casting structure 3 is provided on one side of the ejection seat 201 of the first delayed ejection structure 108 .

[0062] like Figure 1 and Figure 3 As shown, the present bracket product is provided with a plurality of side reinforcement rib structures 4, and correspondingly, a plurality of delayed ejection mechanism bodies 2 are also provided. In practice, there are four groups of side reinforcement rib structures 4. Correspondingly, the first delayed ejection structure 108 is used to form the first group of side reinforcement rib structures 401, the second delayed ejection structure 109 is used to form the second group of side reinforcement rib structures 402, the third delayed ejection structure 110 is used to form the third group of side reinforcement rib structures 403, and the fourth delayed ejection structure 111 is used to form the fourth group of side reinforcement rib structures 404. The ejection seats 201 between the four are slightly different. Among them, the side forming cavity 206 of the first delayed ejection structure 108 and the second group of delayed ejection structure 203 is the same. However, the first delayed ejection structure 108 of the first group is additionally provided with a casting structure 3 on one side of the ejection seat 201. The casting structure can be a gate structure such as a bull horn glue injection structure. The bull horn glue injection structure is wound around the bottom to inject glue, and the gate trace is not obvious, which is convenient for demolding. The second delayed ejection structure 109 and the fourth delayed ejection structure 111 have side reinforcement rib structures 4 that are different in size, and thus there are differences between the side molding cavities 206; the side molding cavity 206 of the third delayed ejection structure 110 is further provided with a plug-in structure 5; similarly, the delayed ejection structure 203 can be applied to other side structures, and other molding structures can also be added on the basis of the side molding cavity 206. The structure is flexible and changeable and can adapt to many scenarios.

[0063] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
