Abstract
The utility model discloses a mandril type withdrawing block which comprises a mandril (1) and a movable block (2). The mandril type withdrawing block is characterized in that a base at the bottom of the mandril (1) is connected with a top plate (3), and the upper end of the mandril (1) is integrally connected with the movable block (2). The mandril type withdrawing block has the advantage that the movable (pumping) block at an inverse withdrawing pattern part of a product can be automatically assembled and withdrawn by the mandril type pumping block when the core of a hot core box is manufactured, so that a sand core can be easily withdrawn, therefore, the work intensity of workers is reduced, and the work efficiency is greatly improved.
Description
Technical field:
The utility model relates to a kind of mould matching appliances, specifically is that a kind of post rod type is taken out piece.
Background technology:
Technical staff in the metal type dies industry is very clear, and in the hot box design process, some product falls the position of withdrawing pattern and must design loose piece, and loose piece has been arranged, and product could take out from mould smoothly.In practical operation, in each coremaking process, all need manually loose piece to be put into mould, after product was cast, the workman took out loose piece in core with hand again, extracted core out, temperature in the core is very high at this moment, and only just there is degree more than 100 on the loose piece surface, and is greatly dangerous in operation, do not note slightly, just be easy to hand is scalded, unsafe factor is high, has increased operator's danger, reduce operating efficiency, improved industrial cost.
The utility model content:
The technical problems to be solved in the utility model is that problem and defective at above-mentioned prior art exists provide a kind of post rod type to take out piece.This post rod type is taken out piece and can be finished automatically when coremaking and get loose piece and dress loose piece, can reduce workman's working strength and increases work efficiency greatly.
Technical solution of the present utility model is to provide a kind of post rod type with following structure to take out piece.
A kind of post rod type is taken out piece, comprises push rod and loose piece, it is characterized in that, the push rod base part seat is connected on the top board, and the upper end and the loose piece of push rod fuse.
After adopting above structure, compared with prior art, the utlity model has following advantage: in the coremaking process of hot box, take out piece by this post rod type, automatically finish packaged the joining and taking-up work of work (taking out) at the product position of falling the withdrawing pattern, and then extract core very like a cork, thus workman's working strength reduced, and improved operating efficiency greatly.
Description of drawings:
Fig. 1 takes out the piece schematic diagram for the utility model post rod type;
Fig. 2 is the M-M generalized section among Fig. 1.
Shown in the figure: 1, push rod, 2, loose piece, 3, top board, 4, external mold.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Illustrated in figures 1 and 2, the utility model post rod type is taken out piece, comprises push rod 1 and loose piece 2, it is characterized in that, push rod 1 base part seat is connected on the top board 3, and the upper end of push rod 1 and loose piece 2 fuse.
Two states when two post rod types shown in Figure 1 are taken out piece and represented matched moulds and die sinking respectively.When wherein a post rod type is taken out piece 1,2 and is in the matched moulds state, live (taking out) piece 2 under the effect of top board, after closely cooperating with external mold 4, make core; When another root post rod type is taken out piece 1,2 and is in die opening state, after the core moulding, enter the die sinking stage, live (taking out) piece 2 under the promotion of top board 3, leave external mold 4 to the height of setting,, thereby in the horizontal direction displacement has been arranged also in gradient groove because of work (taking out) piece 2 moves up and down, make (taking out) piece 2 alive can leave core, just can take out core this moment more conveniently.
Claims (1)
