[0033] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0034] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0036] The embodiment of the utility model provides an integrated molding die for automobile parts, comprising:

[0037] Upper mold assembly 1;

[0038] Lower mold assembly 2;

[0039] An upper die core 101 is disposed in the upper die assembly 1, and the upper die core 101 is connected to a limiting block 102 for limiting the position of the pre-installed metal disc;

[0040] The lower mold core 201 is arranged in the lower mold assembly 2, and is provided with a pre-installed part 21 for pre-installing a metal disk and an insert block 202 for pre-installing a power plug. The insert block 202 is provided with a plug-in slot 203 for plugging in the power plug, and the insert block 202 is provided with an inclined block 204. The lower mold core 201 is provided with a accommodating space 206 for installing the insert block 202, and the accommodating space 206 is provided with a first through groove 207 that cooperates with the inclined block 204.

[0041] When the auto parts are injection molded, the metal disc and the power plug need to be pre-installed. When the metal disc is pre-installed, the metal disc needs to be pre-installed into the pre-installation part 21 first. When the power plug is pre-installed, the power plug needs to be pre-installed into the plug slot 203 of the insert 202, and then the insert 202 is installed into the first through slot 207. After the pre-installation is completed, the mold is closed for injection molding. When the mold is closed, the limit block 102 in the upper mold core 101 will limit the position of the metal disc to prevent it from moving during the injection molding process. After the injection molding is completed and cooled, the plastic part is removed. At this time, the insert 202 is connected to the plastic part, and the insert 202 needs to be removed for the next injection molding.

[0042] The insert block 202 is designed to fix the power plug and plug the power plug to ensure that the power plug can be correctly installed on the insert block 202. The inclined block 204 is installed on the insert block 202. The inclined block 204 assists the movement and positioning of the insert block 202 during the opening and closing of the mold. A first through groove 207 is provided in the accommodation space 206 of the lower mold core 201. The through groove cooperates with the inclined block 204 to ensure that the insert block 202 can slide and position smoothly.

[0043] In some embodiments, a connector 208 for plugging in a power plug is disposed at the front end of the insert block 202 , and there are two plug slots 203 symmetrically disposed in the connector 208 .

[0044] The independent setting of the plug-in component 208 allows it to use different materials according to different needs. For example, a material that is not easy to adhere to the plastic component can be used to facilitate separation from the plastic component.

[0045] Furthermore, a slot 209 is provided in the middle of the plug-in component 208 , and a partition column 210 is provided on the plug-in component 208 , which is inserted into the slot 209 and divides the slot 209 into two parts, and the two parts divided by the slot 209 are two plug-in slots 203 respectively.

[0046] The partition column 210 in the slot 209 divides the slot 209 into two parts, ensuring the accurate position of the two plug slots 203, which helps to evenly install the power plug. The design of using the partition column 210 to divide the slot 209 into two parts allows only one slot 209 to be produced during the production of the plug 208, and then the slot 209 can be divided into different shapes and sizes according to different needs, thereby improving production efficiency.

[0047] Furthermore, the connector 208 and the insert 202 are detachably connected.

[0048] The detachable connection design between the insert 202 and the connector 208 allows the insert 202 to be installed with other idle connectors 208 pre-installed with power plugs to continue injection molding when the plastic part is demoulded, because the connector 208 remains in the plastic part, thereby improving production efficiency. When the connector 208 is pulled out of the plastic part, it can be reused.

[0049] In some embodiments, the size of the plug slot 203 matches the size of the insertion position of the power plug.

[0050] In some embodiments, the lower mold core 201 is provided with a placement groove 211 for assisting in fixing the rear end of the power plug.

[0051] The placement groove 211 provided on the lower mold core 201 for assisting in fixing the rear end of the power plug helps to assist in fixing the power plug and ensure its correct position during the injection molding process.

[0052] In some embodiments, the inclined block 204 includes a first sliding block 212 arranged on both sides of the embedment block 202 and a second sliding block 213 arranged at the rear end of the embedment block 202, and the first through groove 207 includes a second through groove 214 cooperating with the first sliding block 212 and a third through groove 215 cooperating with the second sliding block 213.

[0053] During demolding, the ejection mechanism in the mold pushes upward, and while the plastic part moves upward, the insert 202 moves obliquely outward under the guidance of the first sliding blocks 212 on both sides and the second sliding block 213 at the rear end, so that the insert 202 is separated from the plastic part during demolding, completing the demolding.

[0054] In some embodiments, a protrusion 103 for limiting the pre-installed metal disk is provided at the bottom of the limiting block 102.

[0055] The presence of the protrusion 103 can prevent the metal disk from shifting due to mold movement or plastic flow during the injection molding process, which is crucial to maintaining the integrity of the product structure.

[0056] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
