Abstract
The utility model discloses a die thimble which comprises a cylindrical thimble rod, a cylindrical thimble countersunk head which form a whole with the cylindrical thimble rod; the cylindrical thimble countersunk head is arranged on one end of the cylindrical thimble rod; the outside diameter of the cylindrical thimble countersunk head is larger than the outside diameter of the cylindrical thimble rod; and the outside diameter of the end with the cylindrical timble countersunk of the cylindrical thimble rod is smaller than the outside diameter of the other end of the cylindrical thimble rod. The die thimble can effectively reduce the friction between the thimble rod and the inner surface of installation holes on the die and prolong the service life of the die thimble, and the use is convenient.
Description
Affiliated technical field
The utility model relates to a kind of mould thimble that is used to eject moulded products, more particularly, relates to a kind of structural improvement of mould thimble.
Background technology
The mould thimble is the goods that are used to eject die for molding, traditional mould thimble is by the cylindrical, top shank, constitute with the cylindrical thimble countersunk head of cylindrical, top shank one, this cylindrical thimble countersunk head is positioned at an end of cylindrical, top shank, and cylindrical thimble is the cylinder that an external diameter equates, the mould thimble of this structure is installed in the mould in the mould thimble installing hole, when needs eject moulded products, the thimble rod of mould thimble stretches out in installing hole, the type goods of dressing up eject, therefore there is following defective in the mould thimble of this structure, and whole thimble rod contacts with the installing hole inner surface, when thimble rod moves back and forth, rub with the installing hole inner surface, thereby cause thimble rod outer surface mill flower, make the thimble rod outer surface become coarse, and make the wearing and tearing of thimble rod outer surface, shortened the service life of mould thimble greatly, and because the contact area of thimble rod and installing hole inner surface is big, need the goods of moulding could be ejected, use inconvenience with bigger thrust.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective in the prior art: provide a kind of installing hole inner surface friction that can effectively reduce on thimble rod and the mould, the use mission that prolongs the mould thimble, and mould thimble easy to use.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of mould thimble is provided, comprise the cylindrical, top shank, cylindrical thimble countersunk head with cylindrical, top shank one, this cylindrical thimble countersunk head is positioned at an end of cylindrical, top shank, and the external diameter of cylindrical thimble countersunk head is greater than the external diameter of cylindrical, top shank, and described cylindrical, top shank has the external diameter of the external diameter of cylindrical thimble countersunk head one end less than the cylindrical, top shank other end.
The beneficial effect of mould thimble described in the utility model is: the external diameter with cylindrical thimble countersunk head one end of described mould thimble is less than the external diameter of the cylindrical, top shank other end, can effectively reduce the installing hole inner surface friction on thimble rod and the mould, prolong the use mission of mould thimble, and easy to use.
Below in conjunction with drawings and Examples mould thimble described in the utility model is described further:
Description of drawings
Fig. 1 is the front view of mould thimble described in the utility model;
Fig. 2 is the I place enlarged drawing of Fig. 1.
The specific embodiment
Below the most preferred embodiment of mould thimble described in the utility model, therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, a kind of mould thimble is provided, comprise cylindrical, top shank 1, cylindrical thimble countersunk head 2 with cylindrical, top shank 1 one, this cylindrical thimble countersunk head 2 is positioned at an end of cylindrical, top shank 1, and the external diameter of cylindrical thimble countersunk head 2 is greater than the external diameter of cylindrical, top shank 1, and described cylindrical, top shank 1 has the external diameter of the external diameter of cylindrical thimble countersunk head 2 one ends less than cylindrical, top shank 1 other end.
Because the external diameter with cylindrical thimble countersunk head 2 one ends of mould thimble, can effectively reduce the installing hole inner surface friction on thimble rod 1 and the mould less than the external diameter of cylindrical, top shank 1 other end, the use mission that prolongs the mould thimble, and easy to use.
