Description

Technical Field

[0001] The utility model belongs to the technical field of foam production, and specifically relates to a production mold for rear camera foam. Background Art

[0002] Camera foam, as one of the auxiliary materials for die-cut mobile phones, is used in every smartphone. With the development of smartphones, the requirements for camera foam are getting higher and higher. When processing camera foam, the molten raw material is usually added directly into the mold cavity through the liquid inlet channel.

[0003] A Chinese patent with application number CN202223028155.5 discloses a production mold for rear camera foam, including a box body, the bottom wall of which is fixedly connected to a lower mold core, both side walls of the box body are provided with cooling cavities, the left side wall of the box body is hinged with a cover plate, the lower surface of the cover plate is fixedly connected to a bracket, the upper surface of the cover plate is fixedly installed with a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to a pressure plate.

[0004] The above scheme squeezes the push plates on both sides so that the bottom plate extrude the molded part. However, in actual use, the push plates on both sides are squeezed simultaneously, and the force is difficult to control. It is inconvenient for one person to operate, which may easily lead to uneven force on the push plates on both sides, resulting in poor mold demolding effect. The cover plate and the support block are fixed by bolts, which is inconvenient during the use of the mold, resulting in reduced processing efficiency. In addition, long-term disassembly of the bolts may easily cause damage to the connection.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0029] One aspect of the application of this embodiment is as follows: when in use, the mounting plate 7 is rotated, one side of the mounting plate 7 squeezes the block 112, and the block 112 is forced to move into the slide groove 111. When the mounting plate 7 contacts the support plate 115, the block 112 is connected to the slot 114 under the action of the spring, so as to limit the mounting plate 7;

[0030] The molten material is poured into the lower mold 2. Under the action of the hydraulic cylinder 8, the upper mold 10 and the lower mold 2 are driven to close the mold.
