Abstract
The utility model relates to a mold, and in particular relates to a mold ejector pin, comprising an ejector pin rod, and an ejector pin countersink integrated with the ejector pin rod, wherein the ejector pin countersink is arranged at one end of the ejector pin rod, and the outer diameter of the ejector pin countersink is more than that of the ejector pin rod. The mold ejector pin is characterized in that the ejector pin rod is of a two-segment structure and comprises a first ejector pin rod and a second ejector pin rod, the outer diameter of the second ejector pin rod is less than that of the first ejector pin rod, and the ejector pin countersink is positioned at one end of the second ejector pin rod. Compared with the prior art, the mold ejector pin is of a two-segment structure and has two different outer diameters, so that the friction of the ejector pin rod and the inner surface of a mold mounting hole can be effectively alleviated, the service life of the mold ejector pin is prolonged, and the mold ejector pin is convenient to use.
Description
Technical field
The utility model relates to a kind of mould, is exactly a kind of mould thimble specifically.
Background technology
The mould thimble is be used to the goods that 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 with bigger thrust, use inconvenience.
Summary of the invention
The utility model provides a kind of mould thimble in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of mould thimble, comprise thimble rod, and with the thimble countersunk head of thimble rod one, the thimble countersunk head is positioned at an end of thimble rod, and the external diameter of thimble countersunk head is greater than the external diameter of thimble rod, it is characterized in that: thimble rod is the two-part structure, comprise first thimble rod and second thimble rod, the external diameter of second thimble rod is less than the external diameter of first thimble rod, and the thimble countersunk head is positioned at an end of second thimble rod.
Described first thimble rod and second thimble rod adopt and are welded to connect.
The utility model is compared with prior art, and the mould thimble is the two-part structure, and has two kinds of various outer diameter sizes, can effectively reduce the friction of thimble rod and mould installing hole inner surface, prolongs the use mission of mould thimble, and easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1,1 is first thimble rod; 2 is second thimble rod; 3 is the thimble countersunk head.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises thimble rod, and with the thimble countersunk head of thimble rod one, the thimble countersunk head is positioned at an end of thimble rod, and the external diameter of thimble countersunk head is greater than the external diameter of thimble rod, and the thimble rod in the present embodiment is the two-part structure, comprises first thimble rod 1 and second thimble rod 2, the external diameter of second thimble rod 2 is less than the external diameter of first thimble rod 1, and thimble countersunk head 3 is positioned at an end of second thimble rod 2.First thimble rod 1 in the present embodiment and second thimble rod 2 adopt and are welded to connect.
Compare with prior art, the mould thimble is the two-part structure, and the outside dimension of second thimble rod is less than the outside dimension of first thimble rod, when second thimble rod makes in motion, can effectively reduce the friction of second thimble rod and mould installing hole inner surface, prolong the use mission of mould thimble, and easy to use.
Claims (2)
1. mould thimble, comprise thimble rod, and with the thimble countersunk head of thimble rod one, the thimble countersunk head is positioned at an end of thimble rod, and the external diameter of thimble countersunk head is characterized in that greater than the external diameter of thimble rod: thimble rod is the two-part structure, comprises first thimble rod and second thimble rod, the external diameter of second thimble rod is less than the external diameter of first thimble rod, and the thimble countersunk head is positioned at an end of second thimble rod.
