Abstract

The utility model relates to the technical field of production of grinding discs and in particular relates to a mould for pressing multiple grinding discs. The mould comprises a mould frame and a mould core; and the mould core comprises a bottom core and an upper pressing core. The mould is characterized by further comprising at least one middle core; the lower surface of the middle core has the same structure as the lower surface of the upper pressing core; the upper surface of the middle core has the same structure as the upper surface of the bottom core; the exterior of the middle core is the same as the mould core; and the height of the cavity of the mould core placed in the mould frame is greater than or equal to the total height of the bottom core, the middle core and the upper pressing core. The mould for pressing the multiple grinding discs provided by the utility model has the advantages of being high in production efficiency, making full use of the resources of a press, and producing multiple grinding discs on one side.

Description

Extrude the mould of many abrasive discs

Technical field

The utility model relates to the production technical field of abrasive disc, particularly relates to a kind of mould that extrudes many abrasive discs.

Background technology

The mould of producing abrasive disc comprises framed and core rod; Core rod comprises end core and upper pressing core; Abrasive disc is just processed in the middle of core and the upper pressing core end of at, in the prior art, and core and a upper pressing core at the bottom of a cover core rod comprises one; Such mould once can only be produced an abrasive disc, has the shortcoming that production efficiency is low, waste the press resource.

Summary of the invention

The purpose of the utility model is exactly to above-mentioned shortcoming, and the mould that once extrudes many abrasive discs that a kind of production efficiency is high, the resource of press can make full use of is provided.

The technical scheme of the utility model is achieved in that the mould that extrudes many abrasive discs; Comprise framed and core rod; Core rod comprises end core and upper pressing core again, it is characterized in that: further comprising at least one intermediate core, the same with above the end core of the same, the top structure below the structure below the intermediate core and the upper pressing core; The outside of intermediate core is the same with core rod, and the height of said framed placement core rod cavity is more than or equal to end core, intermediate core and upper pressing core height sum.

The beneficial effect of the utility model is: the resource that the mould of so many abrasive discs of extrusion has production efficiency height, press can make full use of, the advantage of an adnation output multi-disc mould.

Description of drawings

Fig. 1 is the cross section structure sketch map of the utility model mould of extruding many abrasive discs.

Wherein: 1, framed 2, end core 3, upper pressing core 4, intermediate core.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1; Extrude the mould of many abrasive discs, comprise framed 1 and core rod, core rod comprises end core 2 and upper pressing core 3 again; It is characterized in that: further comprising at least one intermediate core 4; The same, top structure below structure below the intermediate core 4 and the upper pressing core 3 the same with above the end core 2, the outside of intermediate core 4 is the same with

core rod

2,3, and the height of said framed 1 placement core rod cavity is more than or equal to end core 2, intermediate core 4 and upper pressing core 3 sums highly.

Can once can suppress a plurality of abrasive discs between upper pressing core 3 and the intermediate core 4, between intermediate core 4 and the end core 2 and place powder metallurgy between intermediate core 4 and the intermediate core 4 like this, boost productivity.

Claims

1. extrude the mould of many abrasive discs; Comprise framed and core rod; Core rod comprises end core and upper pressing core again, it is characterized in that: further comprising at least one intermediate core, the same with above the end core of the same, the top structure below the structure below the intermediate core and the upper pressing core; The outside of intermediate core is the same with core rod, and the height of said framed placement core rod cavity is more than or equal to end core, intermediate core and upper pressing core height sum.
