Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to a shaping mold. Background Art

[0002] This type of product, which has two grooves spaced apart on one side of a square body, is widely used in daily life. For example, our company produces anti-drilling posts for lock cores. The anti-drilling posts for lock cores have the following functions: the lock core has a complex structure and high-hardness materials are not conducive to processing, and it needs to be corrosion-resistant. Generally, copper or copper alloys, austenitic stainless steel and other low-hardness and corrosion-resistant materials are used. The lock core made of these materials is easily damaged by external forces. For example, drilling holes in the lock core with an electric drill can break the lock open. The anti-drilling post for the lock core is a part installed in the lock core. When the lock core is damaged, it reaches the position of the anti-drilling post and is blocked by the high hardness of the anti-drilling post, which will increase the drilling time and prevent the lock from being quickly damaged.

[0003] This product requires high consistency in the width of the two slots. This product is sintered using powder metallurgy, but the product sintered using powder metallurgy is deformed. The slot of the sintered product is deformed outward, and a shaping die is needed to be used to squeeze it from the outside for shaping, and a pair of slot shaping sheets matching the slots need to be set in the shaping die.

[0004] Since the distance between the two grooves on the product obtained by powder metallurgy sintering varies, it is difficult to insert two notch shaping sheets into a pair of grooves of the product at the same time when placing the product into the shaping mold, which will make the product difficult to install and the shaping process time-consuming and difficult. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings and defects mentioned in the above background technology and provide a shaping mold which is easy to install a product.

[0006] In order to solve the above technical problems, the technical solution proposed by the utility model is:

[0007] A shaping die comprises an upper die and a lower die base, the upper die being arranged on the lower die base, a shape shaping groove being arranged at the junction of the upper die and the lower die base, a shaping insert being fixedly arranged on the lower die base near the shape shaping groove, a pair of elastic notch shaping sheets being movably arranged in the shaping insert, one end of the elastic notch shaping sheet extending to the outside of one side of the shaping insert into the shape shaping groove, and the other end extending to the outside of the other side of the shaping insert and fixedly arranged on a mounting seat, the mounting seat being movably arranged in the lower die base, and a driving assembly being connected to the mounting seat for driving the mounting seat to slide in the lower die base.

[0008] In the above-mentioned shaping die, preferably, the lower die base is provided with a positive step, the upper die is provided with an inverted step, the upper die cover is provided on the lower die base, the positive step and the inverted step are arranged opposite to each other up and down and are used to form the shape shaping groove.

[0009] In the above shaping die, preferably, a partition is provided between the pair of elastic notch shaping sheets for separating the pair of elastic notch shaping sheets. The partition is used to separate the distance between the two elastic notch shaping sheets to correspond to the positions of the two notches in the product.

[0010] In the above shaping mold, preferably, the partition and the pair of elastic notch shaping pieces are clamped in the mounting seat by a clamp. A clamping hole can be provided on the partition and the elastic notch shaping piece, so that the three can be clamped in the mounting seat by the clamp and slide synchronously with the mounting seat.

[0011] In the above shaping die, preferably, the shaping insert is fixed in the lower die seat by a pin. The shaping insert needs to be fixed in the lower die seat, and the pin can be used to facilitate the shaping insert to be fixed in the lower die seat.

[0012] In the above shaping die, preferably, the outer shape of the shaping insert at the outer shape shaping groove matches the inner cavity shape of the outer shape shaping groove.

[0013] In the above shaping die, preferably, the driving assembly includes a cylinder and a connecting rod, and the cylinder is connected to the mounting seat through the connecting rod. The cylinder may also be provided with auxiliary components such as a trachea joint and a tie rod assembly. The driving assembly may drive the mounting seat to slide in the lower die seat, so as to pull the elastic notch shaping sheet out of the product after shaping is completed.

[0014] In the above shaping die, preferably, a guide column assembly is provided between the upper die and the lower die seat, and the guide column assembly is used for guiding the upper die and the lower die seat.

[0015] The shaping die of the utility model can be used to shape the product through the shape shaping groove and the elastic notch shaping piece. Since the deformation degree of the sintered product is inconsistent, if the notch shaping piece is set to be fixed, a large part of the product cannot be put in, and it is difficult to load the product into the shaping die. The utility model adopts two elastic notch shaping pieces with elasticity. When the two shaping pieces are inserted into the two grooves of the product at the same time, they can automatically deform according to the position of the groove because of the elastic deformation. They can enter the groove of the product according to the different deformed products, so that the product can be loaded into the shaping die easily.

[0016] In the utility model, the elastic notch shaping sheet and the lower die seat are an integral whole, and do not need to be disassembled when not needed for shaping. When working, the product is manually held by hand and the product notch is inserted into the elastic notch shaping sheet so that the installation is completed. When taking out the product, the elastic notch shaping sheet can be pulled out by the cylinder by just opening the cylinder valve.

[0017] In the utility model, the shaping insert adopts a high-hardness wear-resistant insert, the elastic notch shaping piece is elastic and is made relatively long relative to the groove depth of the product, which is convenient for adaptive positioning, and the material strength of the elastic notch shaping piece does not affect the shaping of the product.

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] The shaping mold of the utility model adopts two elastic elastic notch shaping pieces. When the two shaping pieces are inserted into the two grooves of the product at the same time, they can automatically deform according to the positions of the grooves because of the elastic deformation. They can adaptively enter the grooves of the product according to the different deformed products, which is convenient for the product to be loaded into the shaping mold. The product is easy to install and the mold installation difficulty is small. The product mold installation time can be reduced, which is conducive to improving the processing efficiency.
