TECHNICAL FIELD
[0001] The utility model relates to the mould manufacturing field especially relates to a cabinet body forming mould with adjustable hole mould group. BACKGROUND
[0002] In the current manufacturing industry, thin cabinet products are popular due to their simplicity and versatility. These cabinet products are usually produced by molding to ensure their dimensional accuracy and appearance quality. However, during the mold making process, the small spacing between the panels of the thin cabinet makes it difficult to drill holes in the formed cabinet panels.
[0003] Traditionally, drilling is usually done after the cabinet is formed, which requires the use of specialized drilling tools. However, in the case of thin cabinets, due to the close spacing of the panels, the drilling tool often cannot reach the position where drilling is required, resulting in a time-consuming and labor-intensive drilling process, and easily damaging the cabinet panels, affecting the overall quality and aesthetics of the product.
[0004] In the prior art, a mold with a forming cylindrical hole can be used to realize the opening in SMC molding, but since the positions of the holes required by different parts are different, if different molds are opened for the production of holes in different positions, the cost is high.
[0005] Therefore, it is a technical problem for those skilled in the art to develop a cabinet body forming mold with adjustable hole mold group to realize the synchronous forming of holes in different positions during the mold production process. INVENTION CONTENTS
[0006] To solve the problems in the background art, the utility model develops a cabinet body forming mold with adjustable hole mold group, which includes a lower mold. The lower mold is a rectangular mold with multiple plate-shaped grooves parallel on the upper part. A model groove is horizontally provided on one side of the plate-shaped groove. Multiple standard blocks and multiple hole-forming blocks are parallel arranged in the model groove. The standard blocks and the hole-forming blocks are arranged side by side to fill the model groove. The hole-forming block includes a front block and a rear block, which can be detached. A forming cylinder is provided on the front part of the front block.
[0007] Further, the number of standard blocks arranged in the plate-shaped groove is not less than one.
[0008] Further, the number of hole-forming blocks arranged in the plate-shaped groove is not less than one.
[0009] Further, the model groove is provided on the side edge of the lower mold, and multiple standard blocks and multiple hole-forming blocks are parallel arranged in the model groove outside the lower mold. The standard blocks and the hole-forming blocks are arranged side by side to fill the model groove.
[0010] In use, according to the required hole location, fill the mold groove with the standard block and the hole-forming block, place the hole-forming block at the location where the hole is needed, and fill other locations with the standard block. After molding is completed, separate the upper mold, the lower mold and the standard block, remove the rear block of the hole-forming block, and then use a tool to knock out the front block in the formed hole to obtain a cabinet part with a hole.
[0011] Furthermore, a limiting groove is formed on the lower rear side of the model groove. The limiting groove is slightly deeper than the model groove. A limiting part extends downward from the rear of the standard block and is engaged in the limiting groove. The height of the rear block is greater than that of the front block. The rear block is engaged in the limiting groove. The limiting groove can restrict the downward movement of the standard block and the hole-forming block along the Z-axis and the Y-axis. When the model groove is filled with the standard block and the hole-forming block, the movement of the standard block and the hole-forming block along the X-axis is also restricted to ensure the accuracy of the mold opening position.
[0012] Furthermore, the standard block and the hole-forming block, which are set in the model groove on the side of the lower mold, have a transition fillet on the upper outer side of the standard block and a transition fillet on the upper outer side of the front block.
[0013] Preferably, the standard block and the hole-forming block are made of P20 pre-hardened plastic mold steel.
[0014] Preferably, the model slots are provided with no fewer than four.
[0015] The advantages and beneficial effects of this utility model are as follows: By setting adjustable standard blocks and hole-forming blocks in the lower mold, the mold can flexibly adjust the opening position as needed, and realize one-time forming of holes in CMS molding. This allows it to adapt to the production of cabinet parts with various opening requirements, reducing mold manufacturing costs and storage space. The hole-forming block consists of a front block and a rear block. Combined with the limiting groove design behind the mold slot, it effectively restricts the relative position of the standard block and the hole-forming block in the mold. This multi-directional restriction ensures the accuracy of the mold opening position and improves the quality of the cabinet parts. The detachable design of the front and rear blocks of the hole-forming block allows for easy removal of the rear block after CMS molding, simplifying the disassembly process and enabling the hole-forming block to be reused, thus reducing production costs.
