Description

Technical Field

[0001] This utility model relates to the field of composite mold technology, specifically a novel multifunctional composite mold. Background Technology

[0002] Molds are tools used in industrial production to manufacture products with specific shapes and sizes. They are mainly used to process the shape of objects by changing the physical state of materials. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

[0003] Metal stamping dies mainly use a stamping head to extrude metal parts into the die cavity to form them. However, common stamping dies can often only process workpieces of a single specification. When processing slot frames, although the external opening size is the same, their depths are different, and different dies need to be replaced, resulting in low overall applicability of the dies. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of multifunctional composite mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a fixed mold and a moving mold. The fixed mold consists of a base and four combined templates. The four combined templates have identical structures and are sequentially arranged above the base. Each combined template has a mold cavity at its center. The lowest combined template is fixed to the upper end of the base. Adjacent combined templates are fixedly connected by a fixing component. The moving mold consists of an end plate, a punch head, and an extrusion plate. The end plate has a punch head at its bottom center that matches the mold cavity. The extrusion plate is slidably connected to the periphery of the punch head. A hydraulic cylinder is installed above the end plate, and the output end of the hydraulic cylinder is fixed to the end plate. A telescopic cylinder is fixed to the end plate, and the output end of the telescopic cylinder is fixed to the extrusion plate.

[0006] Preferably, guide rods are fixed at the four corners of the bottom of the end plate, and the guide rods pass through the extrusion plate. Guide grooves are provided on the fixed mold at positions corresponding to the guide rods.

[0007] Preferably, the fixing component includes a connecting groove and a locking block. The connecting groove is opened at the connection point on the outside of adjacent combined templates and is symmetrically distributed. A semi-cylinder is fixed in the connecting groove, and a front baffle is fixed at the end of the semi-cylinder. The locking block is inserted into the locking groove, and the locking block has a locking groove with a T-shaped structure.

[0008] Preferably, the opening width of the slot is the same as the diameter of the semi-cylinder, and the inner width is the same as the combined length of the front baffle. The two ends of the card block are arc structures, and the two sides are planar structures. The length of the card block is adapted to the diameter of the connecting groove.

[0009] Preferably, a check block is installed on the inner wall of the slot at a position aligned with the planes on both sides of the card block, and a telescopic groove is opened on the inner wall of the slot at a position corresponding to the check block, and an ejection spring is fixed between the inner side wall of the telescopic groove and the check block.

[0010] Preferably, the combined template has a positioning groove on the top and a matching positioning block on the bottom.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the bottom mold as a composite structure of multi-layer combined templates, not only can normal stamping processing be performed, but also the overall mold cavity depth can be changed by different combinations of the combined templates, so as to process workpieces with different groove depths and realize the diversity of mold processing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 This utility model provides a technical solution: including a fixed mold 1 and a moving mold 2. The fixed mold 1 consists of a base 11 and four combined templates 12. The four combined templates 12 have the same structure and are arranged sequentially above the base 11. Each combined template 12 has a mold cavity 13 at its center. The lowermost combined template 12 is fixed to the upper end of the base 11. Adjacent combined templates 12 are fixedly connected by a fixing component 5. The moving mold 2 consists of an end plate 21, a punch head 22, and an extrusion plate 23. The bottom of the end plate 21... A punch head 22 adapted to the mold cavity 13 is provided at the center of the part. The extrusion plate 23 is slidably connected to the periphery of the punch head 22. A hydraulic cylinder 3 is installed above the end plate 21, and the output end of the hydraulic cylinder 3 is fixed on the end plate 21. A telescopic cylinder 31 is fixed on the end plate 21, and the output end of the telescopic cylinder 31 is fixed on the extrusion plate 23. Guide rods 24 are fixed at the four corners of the bottom of the end plate 21, and the guide rods 24 pass through the extrusion plate 23. A guide groove 14 is provided on the fixed mold 1 at the position corresponding to the guide rod 24.

[0019] In this embodiment, the hydraulic cylinder 3 drives the end plate 21 and the stamping head 22 to move downwards, thereby squeezing the workpiece into the mold cavity 13. Then, the telescopic cylinder 31 drives the extension of the workpiece to be squeezed flat, completing the stamping process. During this process, since the combined template 12 is connected by the fixing component 5, after the fixing is released, the upper combined template 12 can be disassembled, thereby changing the depth of the combined mold cavity 13. During processing, workpieces with different stamping depths can be processed, realizing diverse processing of the mold.

[0020] Please see Figure 1-4 The fixing component 5 includes a connecting groove 51 and a locking block 54. The connecting groove 51 is opened at the connection point on the outside of the adjacent combined template 12 and is symmetrically distributed. A semi-cylinder 52 is fixed in the connecting groove 51, and a front baffle 53 is fixed at the end of the semi-cylinder 52. The locking block 54 is inserted into the locking groove 55. The locking block 54 has a locking groove 55. The locking groove 55 has a T-shaped structure. The opening width of the locking groove 55 is the same as the diameter of the semi-cylinder 52, and the inner width is the same as the combined length of the front baffle 53. The two ends of the locking block 54 are arc structures, and the two sides are flat structures. The length of the locking block 54 is adapted to the diameter of the connecting groove 51. A positioning groove 4 is opened on the top of the combined template 12, and a matching positioning block is opened on the bottom of the combined template 12.

[0021] After the adjacent combined templates 12 are positioned by the positioning groove 4 and the positioning block, the card block 54 can be inserted into the connecting groove 51 at a horizontal angle. After it is fully inserted, the card block 54 can be rotated to make it stand upright. This can limit the up and down movement of the adjacent combined templates 12, and at the same time, the card block 54 cannot be pulled out directly, thereby achieving quick fixation of the adjacent combined templates 12.

[0022] Please see Figure 1 , Figure 3 and Figure 4 A check block 6 is installed on the inner wall of the slot 55 and at the position where the two sides of the slot 54 are aligned. A telescopic groove 61 is opened on the inner wall of the slot 55 at the position corresponding to the check block 6. An ejection spring 62 is fixed between the inner side wall of the telescopic groove 61 and the check block 6.

[0023] After the locking block 54 is rotated to the upright position, the push of the ejector spring 62 can be used to push the check block 6 out of the telescopic groove 61, which can block the rotation of the locking block 54, thereby preventing the locking block 54 from rotating accidentally and slipping out of the connecting groove 51, and ensuring the stable connection of the adjacent combined template 12 during operation.
