Abstract

The utility model relates to an intramode automatic shearing device of a side gate. The device comprises a movable template, a movable mold and a flow channel, wherein an inverted flow channel buckle is arranged below the flow channel, and the flow channel is fixed on the movable mold through the inverted flow channel buckle; a chute is formed in an ejector plate, and a cushion block is arranged at the lower end of a flow channel ejector, is embedded in the chute and is capable of sliding up and down along the slideway of the chute. When the mold is opened to perform a push-out action, the ejector plate pushes a product ejector upwards to push out a product, and a gap of 8mm exists between the lower end of the chute of the ejector plate and the cushion block, so that when the push-out distance of the product ejector is smaller than 8mm, the flow channel ejector is not stressed to push out the flow channel, the flow channel is fixed on the movable mold, and the side gate is automatically cut off when the product is pushed out for a certain distance. As the automatic shearing device is added to the mold, a procedure of manually separating the product from the side gate is omitted, the labor intensity of workers is reduced, and the labor productivity is improved.

Description

Automatic shear in a kind of side gate mould
Technical field
The utility model relates to the plastic injection mould technical field, particularly relates to automatic shear in a kind of side gate mould.
Background technology
At present, the injection moulding plastic cement products of existing side gate charging form, injection back side gate still connects together with goods, need to break off with the fingers and thumb disconnected or shear Separation Product and side gate by tool by hand with mould is outer, so it is big that the shortcoming of this type of mould maximum is labour intensity, production efficiency is low, and automatic shear was not seen at present in the side gate mould that a kind of goods of automatically plastics being injected separate with side gate.
The utility model content
The purpose of this utility model is to provide in a kind of side gate mould that automatically goods of plastics injection is separated with side gate shear automatically with defective at above-mentioned the deficiencies in the prior art, can reduce the operation of artificial Separation Product and side gate, reduce labor intensity, raise labour productivity.
The purpose of this utility model is realized by following technical scheme.
Automatic shear comprises moving platen, dynamic model and runner in a kind of side gate mould; Establish ejector retainner plate, mould pin above moving platen, ejector retainner plate is provided with the ejector retainner plate fixed head, establishes product thimble, runner thimble in the ejector retainner plate fixed head; Described dynamic model is arranged on the top of mould pin, and described product thimble, runner thimble pass the ejector retainner plate fixed head and dynamic model is pegged graft, and the thimble of product thimble passes the bottom that dynamic model withstands on product, and the thimble of runner thimble passes the bottom that dynamic model withstands on runner; It is characterized in that: described runner below is provided with the runner back-off, is fixed on the described dynamic model by this runner back-off; Establish a chute in described ejector retainner plate, the lower end of described runner thimble is provided with a cushion block, and this cushion block is nested in the chute and can slides up and down along the slideway of this chute; Before the mould die sinking was done and ejected action, cushion block was arranged on the upper end of the slideway of chute; The mould die sinking is done and is ejected when action, and described ejector retainner plate upwards promotes the product thimble and ejects product, thereby ejector retainner plate drives chute and moves upward and withstand cushion block up to the lower end of chute and promote the runner thimble and eject runner simultaneously.
Wherein, the slideway length of described chute is 8 millimeters.
Wherein, between described ejector retainner plate fixed head and dynamic model, be provided with spring.
Compared with prior art, automatic shear has following advantage in the side gate mould described in the utility model: 1, owing to increase automatic shear at mould, reduced the operation of artificial Separation Product and side gate, alleviated working strength of workers, raised labour productivity; 2, changed traditional side gate injection mould structure, and it is simple in structure, easy to make.
Description of drawings
Fig. 1 is the structural representation of automatic shear in the utility model side gate mould.
Among the figure: 1 runner, 2 products, 3 runner back-offs, 4 runner thimbles, 5 product thimbles, 6 ejector retainner plate fixed heads, 7 cushion blocks, 8 ejector retainner plates, 9 moving platens, 10 mould pin, 11 dynamic models, 12 chutes, 13 springs.
The specific embodiment
Further describe structure of the present utility model below in conjunction with accompanying drawing.
Automatic shear comprises moving platen 9, dynamic model 11 and runner 1 in a kind of side gate mould; Establish ejector retainner plate 8, mould pin 10 above moving platen 9, ejector retainner plate 8 is provided with ejector retainner plate fixed head 6, establishes product thimble 5, runner thimble 4 in the ejector retainner plate fixed head 6; Described dynamic model 11 is arranged on the top of mould pin 10, described product thimble 5, runner thimble 4 pass ejector retainner plate fixed head 6 and peg graft with dynamic model 11, the thimble of product thimble 5 passes the bottom that dynamic model 11 withstands on product 2, and the thimble of runner thimble 4 passes the bottom that dynamic model 11 withstands on runner 1.
Described runner 1 below is provided with runner back-off 3, is fixed on the described dynamic model 11 by this runner back-off 3.Establish a chute 12 in described ejector retainner plate 8, the lower end of described runner thimble 4 is provided with a cushion block 7, and this cushion block 7 is nested in the chute 12 and can slides up and down along the slideway of this chute 12; Before the mould die sinking was done and ejected action, cushion block 7 was arranged on the upper end of the slideway of chute 12.The mould die sinking is done when ejecting action, described ejector retainner plate 8 upwards promotes product thimble 5 and ejects product 2, owing between the lower end of the chute 12 of ejector retainner plate 8 and the cushion block 7 the 8mm gap is arranged, so product thimble 5 eject distance when not reaching 8mm, runner thimble 4 can stressedly not eject runner, and runner 1 is fixed on the dynamic model 11 inflexibly by runner back-off 3, and after product 2 was ejected a segment distance, side gate will be cut off automatically like this.Eject action when ejector retainner plate 8 continues to do, eject distance when surpassing 8mm, ejector retainner plate 8 drives cushion blocks 7, and cushion block 7 drives runner thimble 4 again and ejects runner 1, wholely like this ejects action and just all finishes.
More than show and described basic principle of the present utility model and principal character and advantage thereof.The technology personage of the industry should understand; the utility model is not subjected to the restriction of above-mentioned implementing regulations; what describe in above-mentioned implementing regulations and the specification is to be used for explanation principle of the present utility model; under the prerequisite that does not break away from the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong in claimed the utility model scope.
The claimed scope of the utility model defines with appending claims and other equivalent.
