Abstract

The utility model provides a novel bent lever angle pin. A circular groove is respectively arranged at the bottom portion of an angle pin and at the end face of an angle pin seat. Two arc ends of a connecting rod are respectively fastened in the circular groove of the bottom portion of the angle pin and the circular groove of the end face of the angle pin seat to connect the angle pin and the angle pin seat into a whole. Inclination of the bent lever angle pin can be 30 degrees and far exceeds angles of ordinary angle pins in the prior art, thereby greatly increasing withdrawal stroke of the angle pin, enhancing strength of the angle pin by dividing the same into two sections, and overcoming shortage of insufficient strength of the angle pins due to relatively long length of the angle pins.

Description

Novel curved bar taper pin
Technical field
The utility model relates to taper pin, specifically a kind of novel curved bar taper pin.
Background technology
In mold manufacturing industry, the barb and the less barb of body of inboard generally adopt taper pin mechanism to withdraw from the plastic cement products, the processing of taper pin mechanism and installation are all very simple, when withdrawing from the product barb, eject the effect of product in addition, therefore on plastic mould, used widely.
The angle of common taper pin is between 3 ° to 15 °, after angle surpasses 15 °, taper pin ruptures easily, and after taper pin length surpasses 100mm, wear-resistant block need be installed in the middle part of taper pin, to increase the intensity and the taper pin mechanism stability of taper pin, so the processing of taper pin mechanism and installation all can become very difficult.
See also Fig. 1, be the inclined pin structure schematic diagram of known technology.The angle of common taper pin 1 can only be accomplished 3 ° to 15 °, and after angle surpassed 15 °, taper pin 1 just was easy to fracture, and the length of taper pin 1 is when longer, and the centre also must install wear-resistant block 2 additional, has increased the processing and the installation difficulty of whole taper pin mechanism.
The utility model content
Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of novel curved bar taper pin is provided.
The utility model provides a kind of novel curved bar taper pin, comprises taper pin, and its bottom is provided with circular groove; The taper pin seat, its end face is provided with circular groove; Connecting rod, its two ends are circular-arc, and the two ends of this connecting rod are sticked in respectively in the circular groove of the circular groove of this taper pin bottom and this taper pin seat end face, and this taper pin and this taper pin seat are connected as one.
Compared with prior art, the gradient of curved bar taper pin can be accomplished 30 ° in the utility model, considerably beyond the angle of common taper pin in the known technology, increased the stroke that withdraws from of taper pin greatly, and taper pin is divided into two sections, improved the intensity of taper pin, remedied taper pin because length is longer, and caused the shortcoming of taper pin insufficient strength.
Description of drawings
Fig. 1 is the inclined pin structure schematic diagram of known technology.
Fig. 2 is the structural representation of the novel curved bar taper pin of the utility model.
Fig. 3 is the motion schematic diagram of the novel curved bar taper pin of the utility model.
The specific embodiment
For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 2, be the structural representation of the novel curved bar taper pin of the utility model.This novel curved bar taper pin comprises taper pin 102, taper pin seat 105, connecting rod 104.This taper pin 102 is located in the male model benevolence 103 of this mould, matches with the barb of the product 101 that molds in its end, and these taper pin 102 bottoms are provided with a circular groove 106.This taper pin seat 105 is fixedly arranged in the liftout plate 108 of this mould, and its end face offers circular groove 107.These connecting rod 104 its two ends are circular-arc being connected between taper pin 102 and the taper pin seat 105, the two ends of this connecting rod 104 engage with the circular groove 106 of these taper pin 102 bottoms and the circular groove 107 of these taper pin seat 105 end faces respectively, and this taper pin 102 is connected to mobilizable one with this taper pin seat 105.
Please continue to consult Fig. 3, be the motion schematic diagram of the novel curved bar taper pin of the utility model.When die sinking, the caster 109 and the male model plate 110 of this mould are opened, the ejecting mechanism that the push rod of injection machine promotes this mould up moves, liftout plate 108 is when up moving, the taper pin seat 105 that is fixed in this liftout plate 108 moves together by connecting rod 104 drive taper pins 102, because taper pin 102 has gradient, when up moving, also withdrawed from the barb of product 101 simultaneously, thereby product 101 is ejected smoothly.
The gradient of curved bar taper pin can be accomplished 30 ° in the utility model, considerably beyond the angle of common taper pin in the known technology, increased the stroke that withdraws from of taper pin 102 greatly, and taper pin 102 is divided into two sections, improved the intensity of taper pin 102, remedy taper pin 102 because length is longer, and caused the shortcoming of taper pin 102 insufficient strength.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
