Description
Technical field
The utility model relates to a kind of mould, particularly relates to inner core pulling and the mechanism of loosing core simultaneously of same position in a kind of mould outward.
Background technology
A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production.The material melted that is heated is injected die cavity by high pressure by concrete finger, after cooling curing, obtains formed products.
Injection mold is a kind of instrument producing plasthetics; Also be the instrument giving plasthetics complete structure and accurate dimension.
Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model and cover half close and form running gate system and die cavity, and during die sinking, dynamic model is separated to take out plastic products with cover half.
In the design process of injection mold, the general slant-top core-pulling mechanism that adopts of loosing core for the inside back-off of general plastic products solves.Slant-top core-pulling mechanism primarily of T-shaped piece, inclined top guide block, the part such as oblique top body composition, wherein, T-shaped piece is slided in the T-slot of ejector retainner plate, and inclined top guide block is arranged on bottom moving platen, and inclined hole is opened in centre, coordinates with oblique top body, play the guiding role to oblique top body.In motion process, injection machine knock-pin promotes end needle plate, and ejector retainner plate and end needle plate move to moving platen direction by thrust, drives pitched roof mechanism to eject along tilted direction, deviates from goods back-off.There is following shortcoming because itself structure composition and operating principle determine it ejecting in motion process of loosing core in pitched roof mechanism: 1, mould easily occur bending and deformation, play thorn, wear and tear, the even situation such as fatigue fracture.2, for longer core pulling distance, just need and longer eject distance, eject the long increase that will cause injection mold thickness of distance, make to be restricted selecting of injection-moulding device.3, in injection moulding production process, the movement velocity that ejects of pitched roof mechanism slowly, must prevent too fast ejecting from causing the appearance of pitched roof mechanism " stuck " phenomenon, ejects motion so slowly and injection cycle will be made elongated, thus reduces the efficiency of injection moulding production.
Summary of the invention
In view of the above-mentioned deficiency of the mould core pulling of prior art.The purpose of this utility model be to provide a kind of have structure simple, loose core effective, can same position inner core pulling and the mechanism of loosing core outward simultaneously in the mould of the advantages such as active mold is impaired.
For realizing above-mentioned purpose of the present utility model, the utility model provides inner core pulling and the mechanism of loosing core simultaneously of same position in a kind of mould outward, in described mould same position simultaneously inner core pulling and the mechanism of loosing core outward comprise: an inner core pulling slide block and an outer core-pulling slide block, described inner core pulling slide block and the opposing parallel setting of described outer core-pulling slide block; One inner core pulling slide block tooth bar and an outer core-pulling slide block tooth bar, described inner core pulling slide block tooth bar and outer core-pulling slide block tooth bar are arranged on the sidewall that described inner core pulling slide block and described outer core-pulling slide block press close to mutually respectively; One gear, described gear is arranged between described inner core pulling slide block tooth bar and outer core-pulling slide block tooth bar, and is meshed with described inner core pulling slide block tooth bar and outer core-pulling slide block tooth bar; One pinion stand and the gear shaft be arranged on described pinion stand, described gear is arranged on described gear shaft; Described inner core pulling slide block and outer core-pulling slide block do reciprocal action under the effect of described gear and inner core pulling slide block tooth bar and outer core-pulling slide block tooth bar.
Operationally, outer core-pulling slide block is subject to power left, is moved to the left, and simultaneously inner core pulling slide block to move right same distance due to the effect of gear.Thus reach inner core pulling and the object of loosing core simultaneously of same position in mould outward.
Advantage of the present utility model and beneficial effect are: have structure simple, loose core effective, can the advantages such as active mold is impaired.

Detailed description of the invention
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is described in detail, but described embodiment is only the use providing and illustrate with explanation, can not be used for limiting scope of patent protection of the present utility model.
As shown in Figures 1 and 2 be inner core pulling and the mechanism of loosing core outward simultaneously of same position in a kind of mould of the present utility model, in described mould same position simultaneously inner core pulling and the mechanism of loosing core outward comprise: inner core pulling slide block 1 and an outer core-pulling slide block 2, described inner core pulling slide block 1 and the opposing parallel setting of described outer core-pulling slide block 2; One inner core pulling slide block tooth bar 3 and an outer core-pulling slide block tooth bar 4, described inner core pulling slide block tooth bar 3 and outer core-pulling slide block tooth bar 4 are arranged on the sidewall that described inner core pulling slide block 2 and described outer core-pulling slide block 3 press close to mutually respectively; One gear 5, described gear 5 is arranged between described inner core pulling slide block tooth bar 3 and outer core-pulling slide block tooth bar 4, and is meshed with described inner core pulling slide block tooth bar 3 and outer core-pulling slide block tooth bar 4; One pinion stand 6 and the gear shaft 7 be arranged on described pinion stand 6, described gear 5 is arranged on described gear shaft 7; Described inner core pulling slide block 1 and outer core-pulling slide block 2 do reciprocal action under the effect of described gear 5 and inner core pulling slide block tooth bar 3 and outer core-pulling slide block tooth bar 4.
Operationally, outer core-pulling slide block 2 is subject to power left, is moved to the left, and simultaneously inner core pulling slide block 1 to move right same distance due to the effect of gear 5.Thus reach inner core pulling and the object of loosing core simultaneously of same position in mould outward.
Advantage of the present utility model and beneficial effect are: have structure simple, loose core effective, can the advantages such as active mold is impaired.
The variant that foregoing is only preferred embodiment of the present utility model and exemplifies; be not used for limiting the utility model; every within spirit of the present utility model and principle; done any need not the amendment of creative thinking and improvement, all should be included within protection domain of the present utility model.
