Abstract
The utility model discloses a novel mould core pulling mechanism, which is simple in structure and reliable in motion. The novel mould core pulling mechanism consists of a locking block (1), a slider (2) and a compression spring (3), wherein both the locking block (1) and the slider (2) are provided with matching structures which are identical in shape and provided with gaps. The novel mould core pulling mechanism can assist the slider in moving during opening and closing of a mould, and accordingly, the problem of failure of the compression spring (3) or damage of the mould caused by jamming of the slider is solved.
Description
Technical field: the utility model relates to core-pulling mechanism commonly used on a kind of mould, especially a kind of novel die core-pulling mechanism.
Background technology: slide block and the ejection of loosing core when general employing compression spring is realized die sinking under mould is loosed core the smaller situation of distance; This type mechanism is owing to receive the restriction of the performance of spring own; Situation such as slide block blocks, spring failure can take place after work a period of time; Cause slide block and loose core in time leaving part, thus a series of problems such as the fracture that occurs loosing core, part appearance.
Summary of the invention: the utility model purpose is to provide a kind of novel die core-pulling mechanism, utilizes mechanism after this improvement can realize this core-pulling mechanism is extracted out accurately, timely and resetted; The utility model is a kind of a kind of improvement on slide block and the basis of latch segment own, promptly on existing workpiece basis, increases a kind of core-pulling mechanism that has Angle Pin that is similar to, and utilizes smooth extraction that the principle of loosing core of Angle Pin realizes this core-pulling mechanism and resets.
The formation of the utility model: a kind of novel die core-pulling mechanism; Become by latch segment, slide block, compression spring set; Have T-shape groove or cylinder groove on the slide block; Do the outstanding of respective shapes on the corresponding latch segment, the two with the matched in clearance of 0.5mm, installs the compression spring in the bottom of slide block in the folding mould.
With prior art relatively, the utility model is improved on the basis of existing mechanism, has T-shape or cylindrical groove on the slide block, done on the latch segment with slide block on the groove shape corresponding outstanding.Improved mechanism is with the matched in clearance of 0.5mm when the folding mould.Lock piece during matched moulds and play the guiding role, cooperate the compression spring during die sinking, arrive assigned address the slide block and the ejection of loosing core.
Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is slide block structure figure.
Among the figure: 1 latch segment, 2 slide blocks, 3 compression springs.
The specific embodiment: as shown in the figure, be example with the T-shape groove, increased identical outstanding of groove shape on a kind of and the slide block 2 on the latch segment 1, the gap that peripheral size will guarantee to have 0.5mm at least with groove can not interfere with each other when the matched moulds guaranteeing.As shown in the figure, in the matched moulds process, latch segment 1 does not all interfere with slide block 2 each other.In the die sinking process, if compression spring 3 lost efficacy or slide block is stuck, so this mechanism can drive the extraction of loosing core through T-shape " both wings " auxiliary slider, thus the problem that can occur before solving.
Claims (1)
1. novel die core-pulling mechanism; Form by latch segment (1), slide block (2), compression spring (3); It is characterized in that: slide block has T-shape groove or cylinder groove on (2); Do the outstanding of respective shapes on the corresponding latch segment (1), the two with the matched in clearance of 0.5mm, installs compression spring (3) in the bottom of slide block (2) in the folding mould.
