Abstract
The utility model discloses a kind of thimble structure of die casting, and this thimble structure comprises: die, and it is located in described die casting, offers through hole in this die; Sleeve, it is fixed in the described through hole of described die; Ejector retainner plate, it is located in described die casting; Thimble, its one end is fixed on described ejector retainner plate, and the other end is located in described sleeve.Because thimble is in the process of motion, just does relative motion with sleeve inner, and do not move each other between the through hole of sleeve and described die, the wearing and tearing of sleeve can be caused in the motion process of therefore thimble and the wearing and tearing of die can not be caused.If when sleeve wears away is larger, between sleeve and thimble, gap is comparatively large, only needs to change sleeve, avoids the problem that burr appear in the product produced; Meanwhile, due to the low price of sleeve, change simple expense low, and the benevolence that need not repair a die, therefore time saving and energy saving and extend the mold use life-span.
Description
[technical field]
The utility model relates to a kind of thimble structure, particularly relates to a kind of thimble structure of die casting.
[background technology]
It is shaping that some metal parts (the safety belt mandrel of such as automobile) on the products such as automobile can use the mode of die casting to carry out usually.
Refer to Fig. 1, Fig. 1 illustrates the thimble structure schematic diagram of a kind of die casting into prior art.As shown in the figure, described thimble 10 one end is fixed on ejector retainner plate 11, and the other end is arranged in the centre hole of die 12.
The centre hole of die casting in process of production, uses gap between a period of time back center 10 and centre hole to strengthen owing to wearing and tearing; Correspondingly, around thimble 10 there is bristle limit in corresponding shaping product position, and shake is ground and sandblasting effectively can not remove burr removing, and after needing, processing procedure spends a large amount of manpower or CNC to remove burr.If repair the centre hole of die 12, costly time-consuming on the one hand, repeatedly repair a die on the other hand and can reduce the mold use life-span.
In view of this, the thimble structure developing a kind of die casting is necessary, to solve the problem in fact.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of thimble structure of die casting, and solving repeatedly weares and teares between prior art thimble structure thimble and centre hole causes gap to strengthen, produce the problem that burr appear in product.
In order to achieve the above object, the thimble structure of the die casting that the utility model provides, this thimble structure comprises:
Die, it is located in described die casting, offers through hole in this die;
Sleeve, it is fixed in the described through hole of described die;
Ejector retainner plate, it is located in described die casting;
Thimble, its one end is fixed on described ejector retainner plate, and the other end is located in described sleeve.
Optionally, described sleeve one end has countersunk head, and described sleeve is fixed on described die by described countersunk head.
Optionally, the external diameter of described sleeve is 8 millimeters, and the internal diameter of described sleeve is 6 millimeters.
Compared to prior art, utilize the thimble structure of die casting of the present utility model, because thimble is in the process of motion, just do relative motion with sleeve inner, and do not move each other between the through hole of sleeve and described die, the wearing and tearing of sleeve can be caused in the motion process of therefore thimble and the wearing and tearing of die can not be caused.If when sleeve wears away is larger, between sleeve and thimble, gap is comparatively large, only needs to change sleeve, avoids the problem that burr appear in the product produced; Meanwhile, due to the low price of sleeve, change simple expense low, and the benevolence that need not repair a die, therefore time saving and energy saving and extend the mold use life-span.
[accompanying drawing explanation]
Fig. 1 illustrates the thimble structure schematic diagram of a kind of die casting into prior art.
Fig. 2 illustrates the structural representation of thimble structure one preferred embodiment into die casting of the present utility model.
[detailed description of the invention]
Please combine again and consult Fig. 2, Fig. 2 illustrates the structural representation of thimble structure one preferred embodiment into die casting of the present utility model.
In order to achieve the above object, the thimble structure of the die casting that the utility model provides, this thimble structure comprises:
Die 21, it is located in described die casting, offers through hole in this die 21;
Sleeve 22, it is fixed in the described through hole of described die 21;
Ejector retainner plate 23, it is located in described die casting;
Thimble 24, its one end is fixed on described ejector retainner plate 23, and the other end is located in described sleeve 22.
Wherein, described sleeve 22 one end can have countersunk head 25, and described sleeve 22 is fixed on described die 21 by described countersunk head 25.
Wherein, the external diameter of described sleeve 22 can be 8 millimeters, and the internal diameter of described sleeve 22 can be 6 millimeters.
Compared to prior art, utilize the thimble structure of die casting of the present utility model, because thimble 24 is in the process of motion, just do relative motion with sleeve 22 inside, and do not move each other between the through hole of sleeve 22 and described die 21, the wearing and tearing of sleeve 22 can be caused in the motion process of therefore thimble 24 and the wearing and tearing of die 21 can not be caused.If when sleeve 22 weares and teares larger, between sleeve 22 and thimble 24, gap is comparatively large, only needs to change sleeve 22, avoids the problem that burr appear in the product produced; Meanwhile, due to the low price of sleeve 22, change simple expense low, and the benevolence 21 that need not repair a die, therefore time saving and energy saving and extend the mold use life-span.
Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification that any those skilled in the art do above-described embodiment based on technical solutions of the utility model, equivalent variations and modification, all fall in protection domain of the present utility model.
