Abstract
In order to overcome the phenomenon that the T-shaped groove of the angle pin is easy to break and block in the traditional technology, the utility model provides an anti-breaking structure of the angle pin for the injection mold, which comprises an angle pin seat, an angle pin, a roller and a pin, wherein the angle pin seat is internally provided with a T-shaped groove, the T-shaped groove consists of a transverse groove and a vertical groove, and the number of the roller is two; a through hole is formed below the angle pin, the pin penetrates through the through hole to facilitate connection of two rollers, and the rollers are arranged inside the transverse groove and in sliding contact with the surface of the bottom of the transverse groove. The utility model discloses an adopt the fixed mode of taper pin gyro wheel, make the taper pin contact surface be rolling friction, operating personnel also is difficult to produce the dead phenomenon of card when taking out like this.
Description
Technical Field
The utility model relates to a taper pin field especially relates to an injection mold is last to prevent breaking structure with taper pin.
Background
The angle pin is an accessory in a mould, is used for injection moulding a side molding surface in a plastic product, and the angle top fixing mode mainly comprises a fixing mode of an angle pin T groove.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the defects in the background art, the anti-breaking structure for the inclined pin on the injection mold is provided.
The technical scheme is as follows: an inclined pin anti-breaking structure for an injection mold comprises an inclined pin seat, inclined pins, idler wheels and pins, wherein T-shaped grooves are formed in the inclined pin seat, each T-shaped groove consists of a transverse groove and a vertical groove, and the number of the idler wheels is two; a through hole is formed below the angle pin, the pin penetrates through the through hole to facilitate connection of two rollers, and the rollers are arranged inside the transverse groove and in sliding contact with the surface of the bottom of the transverse groove.
Preferably: the roller is a metal roller.
Preferably: the diameter value of the outer ring of the roller is smaller than the width value of the transverse groove.
Preferably: the pin length value is less than the transverse slot length value.
The utility model discloses realize following beneficial effect:
the roller wheels are arranged on the two sides of the taper pin by using the pins in the T-shaped groove, so that the friction mode of the taper pin can be converted from sliding friction to rolling friction, the taper pin cannot be broken and blocked when the taper pin is used, and the machining precision is easy to control.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.
Fig. 1 is the utility model provides a pair of last whole schematic diagram of preventing snapping structure with taper pin of injection mold.
Fig. 2 is a schematic view of the connection between the angle pin and the roller according to the present invention.
In the figure: 1. the device comprises an inclined pin seat, 2 inclined pins, 3 rollers, 4 pins, 5 transverse grooves and 6 vertical grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example one
With reference to the figures 1-2 of the drawings,
the utility model provides an injection mold is last prevents breaking structure with taper pin seat 2 which characterized in that: the device comprises an inclined pin base 2 base 1, an inclined pin base 2, a roller 3 and a pin 4, wherein a T-shaped groove is formed in the inclined pin base 2 base 1, the T-shaped groove consists of a transverse groove 5 and a vertical groove 6, and the number of the roller 3 is two; a through hole is formed below the inclined pin boss 2, the pin 4 penetrates through the through hole to facilitate connection of the two rollers 3, and the rollers 3 are arranged inside the transverse groove 5 and are in sliding contact with the bottom surface of the transverse groove 5. The roller 3 is a metal roller 3.
The diameter value of the outer ring of the roller 3 is smaller than the width value of the transverse groove 5.
The pin 4 length value is less than the transverse slot 5 length value.
Specifically, the utility model provides an angle base 2 is used for the mould die sinking to use of loosing core, and the fixed mode of adoption is angle base 2 gyro wheel 3 fixed mode, is equipped with a gyro wheel 3 respectively in angle base 2 bottom both sides to set up gyro wheel 3 in the transverse groove 5 that T tank bottom set up, make gyro wheel 3 and 5 bottom surfaces of transverse groove realize sliding contact, compare angle base 2T groove fixed mode among the conventional art, the utility model discloses can replace sliding friction with angle base 2 through rolling friction, can prevent like this that angle base 2 can not block extremely, and also be difficult for producing cracked phenomenon, moreover the utility model discloses a 4 length of pin slightly be less than the length of transverse groove 5, roll outer lane diameter slightly is less than the width of transverse groove 5, just so can make gyro wheel 3 arrange transverse groove 5 in, realize corresponding function.
The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
