The utility model content

The purpose of this utility model has been to provide a kind of cold extrusion die of parts, and the die mold insert adopts the partition type structure, and dismounting, maintenance, replacing in being convenient to produce are simple and practical, easy for installation;

Another purpose of the present utility model is to change die, punch, thereby realizes producing different products.

The technical solution of the utility model is: a kind of cold extrusion die of parts, comprise upper bolster, die shoe, punch assemblies, die assembly, guide pillar, the guide pin bushing that matches with guide pillar, punch assemblies comprises punch, punch retainer, convex mould pad successively, the die assembly comprises gripper shoe, die backing plate, die block, die mold insert, it is characterized in that: die that described die mold insert is the partition type structure and die plate insert are formed.

Described punch assemblies also comprises guide-post of die-set, also comprises on the described die assembly and the corresponding mold guide sleeve of guide-post of die-set.

Described die assembly also comprises the thimble that ejects product.

The place, working position of described punch has designed the awl point of the flowability when improving the metal volume transfer.

The height of described awl point is 1.3mm-1.7mm.

The height of described awl point is 1.5mm.

Described punch assemblies and die assembly are fixed on upper bolster and the die shoe by connector respectively.

The material of the processed product of described mould is an aluminum alloy material.

The beneficial effects of the utility model are: the die mold insert adopts the partition type structure, dismounting, maintenance, replacing in being convenient to produce, and can change die and punch, and realize producing different products; When the guiding of guide pillar, guide pin bushing lost efficacy, guide-post of die-set, mold guide sleeve still can play guiding, pinpoint effect; The place, working position of punch has designed the awl point of certain altitude, has improved the flowability when metal volume shifts, and reduces the generation of bad quality; Simple and practical, easy for installation, also provide cost savings greatly.

The specific embodiment

Embodiment 1

Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing: a kind of cold extrusion die of parts, as shown in Figure 1, 2, 3, comprise upper bolster 11, die shoe 4, punch assemblies, die assembly, guide pillar 7, the guide pin bushing 15 that matches with guide pillar 7, the effect that guide pillar 7, the guide pin bushing 15 that is provided with between described upper bolster 11, the die shoe 4 plays guiding, locatees; Described punch assemblies comprises punch 14, punch retainer 13, convex mould pad 12, described punch 14 as shown in Figure 4, described punch 14 is fastened in the described punch retainer 13 fixing, connector passes upper bolster 11, convex mould pad 12, punch retainer 13 successively, punch retainer, convex mould pad are fixed on the upper bolster, thereby make punch assemblies be connected with upper bolster 11; Described die assembly comprises gripper shoe 3, die backing plate 2, die block 1, die mold insert, die 6 that described die mold insert is the partition type structure and die plate insert 5 are formed, described die 6 as shown in Figure 5, connector passes die shoe 4, gripper shoe 3, die backing plate 2, die block 1 successively and gripper shoe, die backing plate, die block is fixed on the die shoe 4, thereby makes the die assembly be fixedly mounted on the die shoe 4; Described die assembly also comprises a thimble 10, when formed product, promotes thimble 10 gently and just can eject product very easily; Punch shown in Fig. 4,5, die match the product 18 produced as shown in Figure 6;

Described die mold insert is built in described die block 1 cavity, and the die 6 of described die mold insert matches with punch 14, and the die plate insert 5 of described die mold insert is arranged on the outer peripheral edges of die 6; Described die mold insert adopts the partition type structure, dismounting, maintenance, replacing in being convenient to produce, and can change die and punch, and realize producing different products;
