Abstract

The utility model provides an ejection pouring gate structure of a mould, which ensures that cold material chips remaining at the pouring gate of the mould are less when the pouring gate is separated from a product, the probability of cold material spots on the surface of the product is low, the qualification rate of products are increased, and the output benefits of the mould are improved. The ejection pouring gate structure of the mould comprises a front moulding plate, a rear moulding plate, a front mould core and a rear mould core, wherein a hollow cavity between the front mould core and the rear mould core is a mould cavity, a runner is communicated with a submarine pouring gate structure after penetrating the front mould core, the submarine pouring gate structure is communicated with the mould cavity, and the bottom of a product ejector is in fastening connection with a combined body of a surface needle plate and a bottom needle plate. The ejection pouring gate structure of the mould is characterized in that the top end of a pouring gate ejector pin is mounted at the submarine pouring gate structure in a propping manner, and the bottom end of the pouring gate ejector pin is in fastening connection with a boss at the top of an ejecting block mould insert after penetrating the surface needle plate.

Description

A kind of mould eject pouring gate structure
Technical field
The utility model relates to the technical field of mould structure, is specially a kind of pouring gate structure that ejects of mould.
Background technology
The mould of existing employing sub marine gate; Find the irregular cold burden spot that occurs on the surface at shaped article through regular meeting; Through analyzing: the runner cold burden bits that produce when last sub marine gate separates with product remain in the mould gate place; Afterwards again during injection mo(u)lding the cold burden bits poured die cavity, be exactly the cold burden spot on our product surface seen.Analyse in depth and find: when the cold burden bits of existing mould ejected when resulting from cast gate and product, instability was broken in the separation process.So existing mould structure can cause the percent defective of product to increase, and influences the output benefit of mould.
Summary of the invention
The utility model provides a kind of pouring gate structure that ejects of mould; Its cold burden bits that make cast gate remain in mould gate when separating with product lack; The cold burden spot probability that appears at product surface reduces, and makes the qualification rate of product increase, and the output benefit of mould is improved.
A kind of mould eject pouring gate structure; It comprises front template, rear pattern plate, front mould core, back model core; Cavity between said front mould core, back model core is a die cavity; Runner is communicated with the sub marine gate structure after running through said front mould core, and said sub marine gate structure is communicated with said die cavity, and the bottom of product thimble is fastenedly connected the combination of face needle plate, end needle plate; It is characterized in that: the top of cast gate thimble is mounted on said sub marine gate structure; The top boss that is fastenedly connected the jacking block mold insert behind said the needle plate is run through in the bottom of said cast gate thimble, and needle plate of the said end has up big and down small jacking block mold insert groove is installed, and the top boss of said jacking block mold insert is installed on the top cell body that said jacking block mold insert is installed groove; Leave the gap between the top boss top end face of the bottom face of said needle plate during matched moulds and said jacking block mold insert, the bottom of said jacking block mold insert is run through the bottom cell body of said jacking block mold insert installation groove and is connected the external drive part.
After adopting the structure of the utility model, after the demoulding, the external drive part drives; The jacking block mold insert rises, owing to leave the gap between the top boss top end face of the bottom face of the face needle plate during matched moulds and jacking block mold insert, the top boss that is fastenedly connected the jacking block mold insert behind the face needle plate is run through in the bottom of cast gate thimble; So the jacking block mold insert drives on the cast gate thimble earlier and pushes up, and makes that sub marine gate is ejected earlier, afterwards after the top of jacking block mold insert boss heads on the bottom face of face needle plate; Product, sub marine gate are ejected simultaneously, and this structure is through ejecting sub marine gate earlier, ejecting product again; The cold burden bits that make cast gate remain in mould gate when separating with product lack; The cold burden spot probability that appears at product surface reduces, and makes the qualification rate of product increase, and the output benefit of mould is improved.
Description of drawings
Fig. 1 is the front view structural representation of the utility model.
The specific embodiment
See Fig. 1; It comprises front template 1, rear pattern plate 2, front mould core 3, back model core 4; The cavity that front mould core 3, back model core are 4 is a die cavity, and position product 5 to be formed in the die cavity, runner 6 run through front mould core 3 backs and be communicated with sub marine gate structures 7; Sub marine gate structure 7 is communicated with die cavity; The bottom of product thimble 8 is fastenedly connected the combination of face needle plate 9, end needle plate 10, and the top of cast gate thimble 11 is mounted on sub marine gate structure 7, and the top boss 13 that is fastenedly connected jacking block mold insert 12 behind the face needle plate 9 is run through in the bottom of cast gate thimble 11; End needle plate 10 has up big and down small jacking block mold insert groove 14 is installed; Top boss 13 is installed on the top cell body that the jacking block mold insert is installed groove 14, leaves gap 15 between the bottom face of the face needle plate 9 during matched moulds and top boss 13 top end faces, and the bottom of jacking block mold insert 12 is run through the bottom cell body of jacking block mold insert installation groove 14 and connected external drive part 16.
