Abstract

The utility model relates to a core-pulling device of double sliding blocks of a mold, comprising a large sliding block, a large sliding pressing plate fixed on a lower inner mold plate and an inclined guide post fixed on an upper inner mold plate, wherein the large sliding block is provided with a central guide rail fixed on the lower inner mold plate. The core-pulling device is characterized in that the bottom part of the large sliding block is provided with at least two small sliding blocks; two sides of the small sliding blocks are provided with small sliding block pressing plates fixed on the lower inner mold plate; the small sliding blocks and the sliding block pressing plates are connected in a sliding manner; the large sliding block is provided with small sliding block pressing seats which correspond to the positions of the small sliding blocks that are provided with embedding needles and are shaped like hook legs; and the small sliding blocks and the embedding needle are fixedly connected. The core-pulling device has simple structure and can improve the production efficiency.

Description

A kind of mould double-slider extracting core apparatus
Technical field
The utility model relates to a kind of core-pulling device of mould, particularly relates to a kind of mould double-slider extracting core apparatus.
Background technology
Generally be equipped with core-pulling device in the existing mould, throw off the back-off part of product when the core-pulling device effect is die sinking, make the smooth demoulding of product.Present core-pulling device mainly be divided into machinery loose core and oil pressure loose core two kinds, wherein to loose core mainly be that angled-lift splits is set in mould to machinery, and match with the skew wall of dies cavity, and slide block slides along skew wall when mould is opened, slide block is laterally opened, and product can be deviate from mould.But angled-lift splits vertically moves when laterally opening simultaneously, and the imagination of garland, breakage appears in the side somatotype part of product easily, seriously reduces the qualification rate of product, and therefore present core-pulling device is generally loosed core based on oil pressure.And when using the oil pressure core-pulling device, must in the mould production process, increase the oil pressure parts, because oil pressure is loosed core and want holding time in the die sinking process, and take consumption injection machine resource, shared die space is bigger simultaneously, when oil leakage phenomenon occurring, the difficult cleaning of mould, the production efficiency of mould is lower so oil pressure is loosed core, and the energy consumption of machine and cost are all higher.For this reason, people have carried out multiple improvement at the oil pressure core-pulling device, as the oil pressure core-pulling device drive mechanical core-pulling device, two oil pressure core-pulling devices and with, machinery is loosed core with the oil pressure core-pulling device and form such as use, but still there is the shortcoming that complex structure, production cycle grow in this improvement.Therefore, existing mould core-pulling device is still waiting further improvement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, the mould double-slider extracting core apparatus that can enhance productivity is provided.
Goal of the invention of the present utility model is achieved in that a kind of mould double-slider extracting core apparatus, comprise big slide block, be fixed on the big slide block pressing plate on the core insert plate and be fixed on Angle Pin on the inner formword, big slide block is provided with and is fixed on center rail on the core insert plate, it is characterized in that: the bottom of described big slide block is provided with at least two small slide blocks, the small slide block both sides are provided with the small slide block pressing plate that is fixed on the core insert plate, between small slide block and the small slide block pressing plate for being slidingly connected.
Described big slide block is provided with the small slide block wedge, and the small slide block wedge is corresponding with the small slide block position.
Described small slide block is provided with pin.
Described small slide block is the tripping kick shape.
Between described small slide block and the pin for fixedlying connected.
The utility model improves the mould core-pulling device of prior art, by bottom slidably small slide block is set at big slide block, big slide block drives small slide block and does the secondary slip during die sinking, small slide block is deviate from easily, so garland or damaged phenomenon on the position of product side somatotype, can not occur on product.In addition, the double-slider extracting core apparatus has saved the oil pressure parts, except having simplified the mold integral structure, problems such as oil circuit sealing, hydraulic oil pollution product also can not occur.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the structural representation of the utility model Angle Pin.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to Figure 1 and Figure 2, mould double-slider extracting core apparatus of the present utility model mainly comprises big slide block 1, big slide block pressing plate 3, Angle Pin 10, center rail 2.Wherein big slide block pressing plate 3 is fixed on the core insert plate 8; Angle Pin 10 is fixed on the inner formword 9, and is slidingly connected with core insert plate 8; Center rail 2 then is fixed on the core insert plate 8.In order to add the stability that powerful slide block 1 is deviate from, and make it deviate from product easilier, at least two small slide blocks 4 are set in the bottom of big slide block 1.Small slide block 4 is the tripping kick shape, and small slide block 4 is provided with pin 7, and pin 7 and small slide block 4 be for fixedlying connected, and when die sinking, moves behind the small slide block 4 pin 7 is deviate from smoothly.In order to strengthen the stability of small slide block 4 die sinkings, be provided with small slide block pressing plate 6 in small slide block 4 both sides, small slide block pressing plate 6 is fixed on the core insert plate 8, and is slidingly connected with small slide block 4.Big slide block 1 is provided with small slide block wedge 5, and the position of small slide block wedge 5 is corresponding mutually with small slide block 4, can play position-limiting action when small slide block 4 slides.Mould double-slider extracting core apparatus of the present utility model is by the secondary slip die sinking of big slide block 1 and small slide block 4, and small slide block 4 is deviate from product easily, so garland or damaged phenomenon can not occur on the position of product side somatotype.In addition, the double-slider extracting core apparatus has saved the oil pressure parts, except having simplified the mold integral structure, problems such as oil circuit sealing, hydraulic oil pollution product also can not occur.
