Description

Technical Field

[0001] The utility model relates to the technical field of cabin molding, in particular to a cabin mold. Background Art

[0002] The cabin body is mainly composed of carbon fiber prepreg sheets that are pre-cut according to the cutting size, and metal embedded inserts that are pre-processed for the interior of the cabin body. During production, the two need to be connected and stacked together by mechanical positioning. However, the carbon fiber prepreg sheets and the metal embedded inserts cannot be directly positioned, so some auxiliary tools are often required to limit the metal embedded inserts before bagging, vacuuming, compacting and curing. In the prior art, the traditional auxiliary means for positioning carbon fiber prepreg sheets and metal embedded inserts are usually to mark lines on the mold or use conventional means such as carbon plate positioning. In the early stage of cabin body molding, it is also necessary to support and fix them by hand, and then release them after the carbon fiber prepreg sheets are cured. This positioning method has low positioning accuracy and poor positioning effect. The relative position accuracy of the carbon fiber prepreg sheets and the metal embedded inserts is difficult to guarantee, resulting in poor quality of the finished product and low pass rate. In addition, the laying speed is slow and the efficiency is low. Utility Model Content

[0003] In view of the deficiencies existing in the prior art, the utility model provides a cabin mold, which solves the problem of poor positioning accuracy of cabin pre-embedded metal parts in the existing cabin molding method.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A cabin mold comprises a bottom plate, columns, a panel, a side plate and a pin-inserting assembly; a side plate is vertically connected to one side of the bottom plate, a panel is installed on the top of the side plate, and a top forming assembly is arranged at the bottom of the panel; two columns are installed on both sides of the side plate, the bottoms of the two columns are provided with block assemblies, and the tops of the two columns are provided with cross beams; a molding cavity for a cabin product is formed between the side plate, the panel and the two columns; pin-inserting assemblies are arranged on the two columns, and the pin-inserting assemblies fix the cabin embedded metal parts in the molding cavity.

[0006] In this scheme, when the pre-embedded carbon fiber prepreg sheet is laid in the molding cavity, the pre-embedded metal parts of the cabin can be positioned in the molding cavity through the pin assembly during the pre-embedding process. The positioning function of the pin assembly can avoid the position displacement of the pre-embedded metal parts of the cabin during the sealing, molding and curing process of the carbon fiber prepreg sheet; it can better ensure the dimensional tolerance of the installation position of the pre-embedded metal parts of the cabin and improve the product qualification rate.

[0007] Furthermore, the insert assembly includes a bottom A insert, a side stopper and a pressure plate; the pressure plate is fixed to the top of the bottom A insert by bolts, and the bottom A insert is fixed to the end of the base plate by bolts; the bottom of the side stopper is fixed to the base plate by bolts, and the top of the side stopper is fixed to the column by bolts.

[0008] In this solution, a pressing plate and a bottom A insert are provided to block the end of the bottom plate to form an edge structure of the molding cavity; this makes the boundary line of the laying of the carbon fiber prepreg sheet clear, and the carbon fiber prepreg sheet is not prone to slipping during the laying, embedding and curing molding process.

[0009] Furthermore, a bottom B insert is provided at the center of the bottom plate, and the bottom B insert is fixed to the side plate by bolts and does not contact the bottom plate.

[0010] Furthermore, the top forming assembly includes a longitudinal beam and two top forming inserts; the two top forming inserts are respectively arranged at two ends of the longitudinal beam.

[0011] In this solution, a longitudinal beam and two top forming inserts are designed at the bottom of the panel for top forming of the cabin product.

[0012] Furthermore, the pin inserting assembly includes a formed pin and a pin inserting pressure plate; a pressure plate groove is provided on the side of the column, and the pin inserting pressure plate is installed in the pressure plate groove by bolts; one end of the formed pin is fixed on the pin inserting pressure plate, and the other end of the formed pin passes through the column into the forming cavity and passes into the positioning hole of the pre-embedded metal part of the cabin.

[0013] In this solution, a pressure plate groove for installing the pin-inserting pressure plate is opened on the column to ensure the stability of the installation of the pin-inserting pressure plate and prevent the pin-inserting pressure plate from moving and causing errors in the positioning of the embedded metal parts of the cabin.

[0014] Furthermore, two sets of pin-setting assemblies are provided on each column.

[0015] Furthermore, a side-molding B insert and two side-molding A inserts are fixed to the side vertical plate by bolts; the side-molding B insert is arranged at the bottom of the side vertical plate, and the two side-molding A inserts are respectively arranged on both sides of the side vertical plate.

[0016] In this solution, a side-molded B insert and two side-molded A inserts are designed, and holes are formed at corresponding positions after the cabin product is molded.

[0017] The beneficial effects of the utility model are:

[0018] The cabin mold provided by the utility model has accurate positioning of each part during assembly and disassembly, and is simple and easy to operate; the boundary positions such as the surroundings and four corners are sealed with parts to form a stable closed area; when laying, the carbon fiber prepreg sheets are pre-cut into a shape with holes, and then the holes are inserted into the protruding positions of the side molding B insert and the side molding A insert to be stacked and laid in sequence; when the carbon fiber prepreg sheets are laid, the boundary areas can be laid flat, and laying defects such as bridging holes are not likely to occur; it can also effectively prevent the carbon fiber prepreg sheets from slipping during curing and molding; the quality of the cabin products is improved, and it is guaranteed that the cabin products meet the delivery requirements.

[0019] The pre-embedded metal parts of the cabin are fixed by forming pins set on the pin pressing plate, which can prevent the pre-embedded metal parts of the cabin from moving during the laying or molding of the carbon fiber prepreg sheets. Compared with the existing hand-held fixing method, it has high positioning accuracy and fast laying speed of the carbon fiber prepreg sheets.

[0020] By utilizing the angle formed by the pin-studded pressure plate and the column, the pre-embedded metal parts of the cabin can accurately maintain their angle with the cabin product when they are pre-embedded in the layers; this avoids the use of conventional carbon plates to position the embedded parts, which would cause the angle to deflect during the subsequent bagging, sealing and curing of the mold into the tank; the positioning accuracy of the pre-embedded metal parts of the cabin is greatly improved, and the quality of the prepared cabin products is guaranteed.
