Abstract
The utility model discloses a die with an ejection mechanism, which comprises a fixed die, a movable die, an ejector pin retaining plate and at least one runner ejector pin. The fixed die and the movable die are correspondingly arranged, the movable die and the fixed die enclose a cavity and a runner when the die is closed, and the runner is provided with a curved hole-shaped communicating part and a runner knockout part. The ejector pin retaining plate is arranged below the movable die in a movable manner. One end of the runner ejector pin is arranged on the ejector pin retaining plate, and the other end of the runner ejector pin can extend in the runner knockout part and form a filling gap with the inner wall of the knockout part. The die with an ejection mechanism can form the filling gap through the ejector pin head and the inner wall of the runner knockout part, so that plastic waste materials can be wrapped on the circumference of the ejector pin head so as to bury the ejector pin head in the waste materials of the runner when the product is molded, falling and deformation cannot occur when the waste materials are knocked out of the runner, and the waste materials can be reliably and effectively knocked out of the runner.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of mould with ejecting mechanism.
Background technology
See also Fig. 4 and Fig. 5, current a kind of mould 1 ' with ejecting mechanism comprises a cover half (figure does not show), a dynamic model 20 and two runner thimbles 30 '.This cover half and dynamic model 20 be oppositely arranged and can be when matched moulds and dynamic model 20 surround die cavity (figure does not show) and runner 22, runner 22 have crooked poroid and interconnecting part 221 that is communicated with die cavity reach offer in dynamic model 20 surfaces deviate from portion 222.After the formed product, form runner waste material 60 in the runner 22, this runner waste material 60 has interconnecting part waste material 61 and deviates from portion's waste material 62 corresponding to runner 22; What this runner thimble 30 ' one end can be resisted against runner waste material 60 deviates from portion's waste material 62.During die sinking, runner thimble 30 ' ejects runner waste material 60, and simultaneously, interconnecting part waste material 61 separates with product.
Yet, above-mentioned mould 1 ' with ejecting mechanism ejects runner waste material 60 in the process of mould 1 ' at runner thimble 30 ', because runner waste material 60 is failed effectively to be bonded on the runner thimble 30 ', thereby usually topple over and cause product to separate the situation that has some setbacks with runner, thereby influence carrying out smoothly of producing because of runner waste material 60.
The utility model content
The purpose of this utility model is to provide a kind of can more reliably eject the runner waste material effectively, thus the mould with ejecting mechanism of enhancing productivity.
To achieve these goals, the utlity model has the mould of ejecting mechanism, comprise a cover half, a dynamic model, a thimble fixed head and at least one runner thimble; The corresponding setting of this dynamic model with cover half, dynamic model and cover half surround die cavity and runner during matched moulds, and this runner has the crooked poroid and interconnecting part of offering on dynamic model that be communicated with die cavity and the runner of offering in the dynamic model surface deviate from portion; This thimble fixed head is installed in the dynamic model below movably; This runner thimble one end is installed on the thimble fixed head, the other end can extend into that runner is deviate from the portion and with deviate from portion's inwall and form the filler space.
As mentioned above, the mould that the utlity model has ejecting mechanism can be deviate from portion inwall formation filler space by thimble head and runner, thereby when shaped article, can the thimble head be embedded within the runner waste material in coating plastic waste material around the thimble head, thereby guarantee that the runner waste material is ejected Shi Buhui and topples over distortion, and then can more reliably eject the runner waste material effectively.
As further improvement, described runner thimble comprises integrated thimble rod and thimble head, and this thimble head is truncated cone shape.
Described runner is deviate from portion and is comprised sprue portion and centre hole portion, and described runner thimble one end can extend within the centre hole portion.
Be equiped with the product thimble on the described thimble fixed head, offer the product centre hole that is communicated with die cavity on the dynamic model, an end of product thimble can pass the product centre hole and be resisted against on the product.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, the mould 1 that the utlity model has ejecting mechanism comprises a cover half 10, a dynamic model 20, two runner thimbles 30, two product thimbles 40 and a thimble fixed head (figure does not show).
See also Fig. 1 and Fig. 2, this dynamic model 20 and cover half 10 corresponding settings, dynamic model 20 surrounds die cavity 21 and runner 22 with cover half 10 during matched moulds, offers the product centre hole 23 that is communicated with die cavity 21 on the dynamic model 20; This runner 22 has a crooked poroid interconnecting part 221 that communicates with die cavity 21 and the runner of offering in dynamic model 20 surfaces offered and deviates from portion 222 on dynamic model 20, this runner is deviate from portion 222 and comprised sprue portion 223 and centre hole portion 224.
This thimble fixed head is installed in dynamic model 20 belows movably, be equiped with two runner thimbles 30 and two product thimbles 40 on the thimble fixed head, this runner thimble 30 comprises integrated thimble rod 31 and thimble head 32, this thimble head 32 is truncated cone shape, runner thimble 30 1 ends system can extend in the centre hole portion 224, and an end of product thimble 40 can pass product centre hole 23 and be resisted against on the product.
See also Fig. 2 and Fig. 3, during the mould matched moulds, product thimble 40 extend into die cavity 21 bottoms, runner thimble 30 pass runner centre hole 23 and extend in the centre hole portion 224 and with deviate from portion's inwall and form the filler space.Raw material injects die cavity 21 from runner 22, after product 50 moulding, forms runner waste material 60 in the runner 22, and this runner waste material 60 has interconnecting part waste material 61 and deviates from portion's waste material 62 corresponding to runner 22; This is deviate from portion's waste material 62 and is coated on around the thimble head 32, and during die sinking, product thimble 40 and runner thimble 30 eject product 50 and runner waste material 60 respectively simultaneously, and runner waste material 60 is in the dialysis and can not toppling over or rupture voluntarily of runner mouth and product 50.
As mentioned above, the mould 1 that the utlity model has ejecting mechanism can be deviate from portion 222 inwalls formation filler space by thimble head 31 and runner, thereby when shaped article, can thimble head 31 be embedded within the runner waste material 60 in coating plastic waste material around the thimble head 31, thereby guarantee that runner waste material 60 is ejected Shi Buhui and topples over distortion, and then can more reliably eject runner waste material 60 effectively.
