Abstract

The utility model relates to a withdrawing device for a metal insert in a plastic product, which is used for separating the plastic product from the metal insert arranged in the plastic product. The withdrawing device is composed of a punching machine, a plunger chip, a base, a movable core, a supporting column and a spring, wherein the plunger chip is fixed at the bottom of the punching machine and the supporting column is fixed at the upper part of the base; the upper end of the supporting column is in butt joint with the plastic product needing to withdraw the metal insert; the movable core is arranged at the top of the spring and the movable core and the spring are arranged in the supporting column. Compared with the prior art, the withdrawing device provided by the utility model has the advantages of accuracy in positioning and simplicity in operation; the recycling rate of the metal insert is 100% and the cost is greatly saved.

Description

The withdrawing device of metal insert in a kind of plastic cement products

Technical field

The utility model relates to a kind of withdrawing device of metal insert, especially relates to the withdrawing device of metal insert in a kind of plastic cement products.

Background technology

At present, in the plastic cement industry, because the needs on the function have a kind of product to place metal insert injection moulding together again, its plastic cement part of the product that forms out closely links to each other with metal insert, can't direct separation.But, if some problem of its shaped article needs to revise, establish change, processing mistake or the like such as the client, the product that then causes moulding is together with the direct subscription rate of metal insert wherein.Generally speaking, the metal insert price comparison is expensive, if direct subscription rate certainly will cause a large amount of risings of production cost; If recycling then must let metal insert separate with plastic cement,, then there are two problems if simple dependence is artificial: the one, operating efficiency is extremely low; The 2nd, metal insert is difficult to separate with plastic cement intactly.

The utility model content

The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of accurate, as can effectively to separate plastic cement and metal insert fast device of locating to be provided.

The purpose of the utility model can realize through following technical scheme:

The withdrawing device of metal insert in a kind of plastic cement products is used to separate the metal insert that is provided with in plastic cement products and the plastic cement products, it is characterized in that; Described withdrawing device is made up of punch press, drift, base, moving core, support column and spring, and described drift is fixedly mounted on the punch press bottom, is driven by punch press to move up and down; Described support column is fixedly mounted on base top;, its upper end connects with the plastic cement products of metal insert to be removed, supports and fix the plastic cement products of metal insert to be removed; Described moving core is arranged on the top of spring, and moving core and spring are located in the support column.

Described support column is supported on the below of the plastic cement part of plastic cement products.

The end face of described moving core is supported on the below of metal insert to be removed.

The upper surface of described moving core is higher than the support column upper surface.

Described drift, its size should be slightly less than the external diameter of the metal insert of required taking-up.

Described punch press, stroke can be regulated about it.

Compared with prior art, the utlity model has following advantage:

1, promotes operating efficiency

Because this withdrawing device is to rely on the punching press of punch press to be used for realizing separating of metal insert and plastic cement products, has adopted semimechanized method, compares with pure manual work, has promoted operating efficiency greatly.

2, practice thrift cost

Rely on pure manual work to come separating metal inserts and plastic cement products; Because the difficulty of separating usually causes the damage of metal insert, then can isolate metal insert intactly with this extraction device; It separates efficient almost reaching absolutely, has practiced thrift cost greatly.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the partial structurtes sketch map of the utility model.

1 is that punch press, 2 is that drift, 3 is that base, 4 is that metal insert, 5 is that plastic cement products, 6 is that moving core, 7 is that support column, 8 is a spring among the figure.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.

Embodiment

The withdrawing device of metal insert in a kind of plastic cement products, its structure are shown in Fig. 1～2, and this withdrawing device comprises punch press 1, drift 2, base 3, metal insert 4, plastic cement products 5, moving core 6, support column 7, spring 8.Drift 2 is set in the bottom of punch press 1; Support column 7 inside are provided with moving

core

6 and 8 liang of parts of spring; Moving core 6 is above spring 8, and the upper surface of moving core 6 must be higher than the upper surface of support column 7, and support column 7 is fixedly mounted on base 3 tops; 3 of bases are fixed on the chassis of punch press 1, and metal insert 4 to be separated is placed on above the support column 7 with plastic cement products 5.Use the step of this withdrawing device following:

(1) earlier drift 2 is installed on the punch press 1;

(2) then the plastic cement products that contains metal insert 45 to be processed is placed on the support column 7;

(3) operating personnel's handle of spurring punch press 1 drives drift 2 and moves downward;

(4) drift 2 under the mechanism of punch press 1 near and the upper surface of contacting metal inserts 4;

(5) metal insert 4 power is passed on the moving core 6, and moving core 6 is passed to power on the spring 8 under the effect of drift 2; Spring 8 is in stressed lower compression;

(6) and plastic cement products 5 under the supporting role of support column 7, keep motionless, thereby the metal insert that makes 4 separates with it.

Claims
