Abstract
The utility model discloses a core die release device, comprising a core shaft. A hole is formed in the lower part of the core shaft, a connecting element is installed in the hole, and the lower end of the connecting element is arranged in the head of a jacking cylinder. According to the core die release device disclosed by the utility model, after a pressing state, a press die does not need to be carried, a core die can be released by virtue of the constant-speed and slow stroke return action of a lower cylinder of a press, and the operation is time-saving and labour-saving; and moreover, core shafts and connecting elements with different specifications are extremely convenient to replace. By virtue of the device, the original total die release time of 6 minutes is shortened to be 3.5 minutes, and the probability of layering cracks is reduced to 3% at present from 10% before an improvement, thus greatly improving the yield of pressing and reducing the return rate of pressed blanks.
Description
Technical field
The utility model belongs to the carbide roll ring production technical field, specifically a kind of core unit that moves back.
Background technology
At present, in the carbide roll ring production technology, for better controlling the phosphorus content of product, domestic adopt made forming agent with PEG or paraffin more.But for rubber, although the caking property of above-mentioned two kinds of forming agents is poor, control carbon is effective, and for reaching higher adhesion strength, only having to adopt increases binding agent and increase two kinds of methods of formed product pressure.Can cause the fluctuation of carbon and hole to increase but increase binding agent, relatively easier dirtyization of product for guaranteeing product quality, makes the product pressed compact that enough intensity (guaranteeing that pressed compact turns in mould, the handling process not cracked) is arranged again, only has the formed product of increase pressure.Along with the increase of formed product pressure, pressed compact more easily forms hierarchical crack after moving back mould.The present core unit that moves back, after the compacting state finishes, whole pressing mold is lifted into moves back on the die holder, mandrel is pressed into by a push rod by press upper pressure head and moves back die holder and realize moving back core, this process both wasted time and energy, and the vibrations in the hoisting process easily make pressed compact cracking, and have the personal security problem adjusting pressing mold and move back in the operation of die holder centering.
The utility model content
Technical problem to be solved in the utility model is to waste time and energy and have the shortcoming of personal security problem and provide a kind of fast demoulding and the time saving and energy saving core unit that moves back for moving back core in the prior art.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of core unit that moves back comprises mandrel, and described mandrel below arranges a hole, and a connection piece is installed in the described hole, and the lower end of described connector is in cylinder head is taken blame for others in setting.
Described connector comprises body, stub end and little head end, and described stub end and microcephaly's end are arranged on the body both sides by linkage section respectively.
The described cylinder head of taking blame for others arranges a groove, and the stub end of described connector is arranged in the groove.
The little head end of described connector is arranged in the hole.
The utility model does not need to move pressing mold after the compacting state finishes, utilize the backhaul action of the uniform speed slow of cylinder under the press can realize moving back core, and is time saving and energy saving, and mandrel and the connector of replacing different size are also very convenient.This device makes original 6 minutes total demould time shorten to 3.5 minutes, and the probability that hierarchical crack occurs is down to present 3% by 10% before improving, greatly improved the presswork rate, has reduced the pressed compact return rate.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 1,2,3,4,5, a kind of core unit that moves back, comprise mandrel 1, take blame for others cylinder head 3 and connector 2, wherein connector 2 is divided into body 202, stub end 204 and microcephaly and holds 201, stub end 204 and microcephaly hold 201 to be connected to body 202 both sides by linkage section 203 respectively.Open a hole 4 below mandrel 1, the microcephaly of hole 4 interior installation a connection piece 2 holds 201, and the microcephaly holds 201 usefulness the first bolt 5 to be fixed on the mandrel 1.Open a groove 8 at the cylinder head 3 of taking blame for others, the stub end 204 of connector 2 is installed in the groove 8 of the cylinder head 3 of taking blame for others, and stub end 204 usefulness the second bolt 5 is fixed in the cylinder head 3 of taking blame for others.Use the utility model to move back core unit after external mold 7 compacting states finish, the take blame for others backhaul action of cylinder head 3 uniform speed slows of primer fluid pressing system utilization can realize moving back core, time saving and energy saving, handling safety, reduced the probability of pressed compact because of the vibrations cracking, and also very convenient for mandrel 1 and connector 2 its replacings of different size.Its concrete step of using is: the hydraulic system of (1), primer fluid press, and the cylinder head 3 of will taking blame for others stretches out press bed; (2), the large end of connector 2 filled 204 enter to take blame for others in the groove 8 of cylinder head 3, connector 2 90-degree rotations, tighten the second bolt 6; (3), with pack into the small end head 201 of connector 2 of the mandrel 1 of dimension, equally mandrel 1 90-degree rotation, tighten the first bolt 5, namely finished the installation of moving back fast core unit and connected.
