TECHNICAL FIELD

[0001] The present application relates to the technical field of manufacturing a recreational vehicle compartment, and particularly relates to a magnetic insert and a mold for manufacturing a whole carbon fiber compartment. BACKGROUND

[0002] With the vigorous development of off-road recreational vehicle culture, more and more people choose to use off-road chassis to carry a living box body to go deep into uninhabited areas or non-paved roads to carry out extreme off-road exploration. However, the weight problem is always a bottleneck restricting off-road performance: the heavier the vehicle, the more limited its passability and off-road capability, and the more difficult the self-rescue. In the related technology, in order to effectively reduce the weight, the compartment is designed as an integrated structure, and a lightweight and high-strength carbon fiber material is used to manufacture the compartment, aiming to greatly reduce the number of connecting pieces in the sandwich structure and abandon the dependence on the metal skeleton.

[0003] In the process of manufacturing the carbon fiber compartment, the manufacturer will design the position and size of the door and window according to the user's demand for the compartment, which makes the compartment body of the carbon fiber compartment have great differences. If the compartment mold is designed and manufactured separately for each compartment body, the number of various compartment molds will undoubtedly increase sharply, and the design and manufacturing costs will also increase greatly.

[0040] The following will be described in detail in combination with Figures 1 to 8 The present application is further described in detail.

[0041] Referring to Figure 1 The embodiment discloses a magnetic insert 100, comprising a first mold 110, a magnet 120 and a connecting piece 130, the magnet 120 is connected to the first mold 110 through the connecting piece 130. In use, the first mold 110 is adsorbed on the mold frame 200 by the magnetic force of the magnet 120, realizing the function of flexibly arranging the first mold 110 on the surface of the mold frame 200.

[0042] The embodiment has a mounting groove 111 on the first mold 110 to accommodate the magnet 120, the shape and size of the mounting groove 111 are adapted to the magnet 120, so as to improve the stability of the magnet 120. The magnet 120 is fixed on the first mold 110 through the connecting piece 130, so as to prevent the magnet 120 from falling off. In use, the first mold 110 is adsorbed on the mold frame 200 by the magnetic force of the magnet 120.

[0043] The connecting piece 130 of the embodiment comprises a bolt 131 and a nut 132, the bolt 131 is screwed with the nut 132 after penetrating through the magnet 120 and the first mold 110, the above connecting mode not only realizes the function of fixedly connecting the magnet 120 and the first mold 110, but also enhances the binding force between the magnet 120 and the first mold 110 through the pre-tightening force of the bolt 131.

[0044] The bolt 131 of the embodiment adopts a countersunk bolt, and a chamfer matched with the countersunk bolt is arranged on the contact surface between the magnet 120 and the head of the countersunk bolt, so that the countersunk bolt can smoothly transition to the surface of the magnet 120, effectively reducing the risk of stress concentration.

[0045] The rubber pad 140 is arranged at the end of the magnet 120 away from the bottom of the mounting groove 111, and is embedded in the mounting groove 111. When the first mold 110 is adsorbed to the surface of the mold frame 200, the rubber pad 140 can play a certain buffering role, avoiding direct contact between the magnet 120 and the mold frame 200, thereby reducing the risk of scratching the mold frame 200 by the magnet 120.

[0046] The embodiment utilizes the magnetic adsorption property of the magnet 120 to easily adsorb the first mold 110 at any position of the mold frame 200, realizes the reuse of the magnetic insert block 100 and the mold frame 200, and reduces the production cost. The embodiment can also adapt to the needs of different customers, reduce the number of carbon fiber carriage molds, and reduce the design and production cost of the carriage mold.
