Furthermore, a rubber pad is arranged on the inner side of the L-shaped plate.

Furthermore, the long bolt is of an integrally formed structure.

Furthermore, the pressing plate is of an integrally formed structure.

The utility model has the advantages that: the utility model discloses a in the time, place the mould in the middle of the template, then fix the mould through rotatory stay bolt, utilize "T" type groove to carry out further fixed to the mould at last, fixed stability is high, improves the shaping quality of core shooter, can match the mould of various shapes moreover, and application scope is wider.

In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided.

The present invention will be described in further detail below with reference to the drawings.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a tectorial membrane core shooter.

In this embodiment, referring to fig. 1 to 4, the film-coated core shooter includes a frame 1, a template assembly and a sand shooting assembly 2, the template assembly includes an upper template 3, a lower template 4, an upper cylinder 5 and a lower cylinder 6, the upper template and the lower template have the same structure, the lower template has a square structure, T-shaped grooves 7 penetrating through the front and rear sides are formed in the upper end surface of the lower template, screw holes 8 are formed in four corners of the lower template, communicated sliding grooves 9 are formed between the screw holes 8 facing each other, long bolts 10 are connected to the screw holes 8 through internal threads, and pressing plates 11 are rotatably connected to the tops of the long bolts 10.

The utility model discloses a in the time, place the mould in the middle of the template, then fix the mould through rotatory stay bolt, utilize "T" type groove to carry out further fixed to the mould at last, fixed stability is high, improves the shaping quality of core shooter, can match the mould of various shapes moreover, and application scope is wider.

Specifically, the long bolt 10 includes a threaded rod 12 having an external thread and a hexagonal head 13; the pressing plate 11 comprises an L-shaped plate 14, a rotating shaft 15 arranged on the L-shaped plate 14 and a limiting disc 16 arranged at the top of the rotating shaft 15, a shaft hole 17 is formed in the top of the long bolt, a limiting groove 18 matched with the limiting disc is formed in the bottom of the shaft hole 17, and the pressing plate is rotatably connected to the shaft hole 17 through a bearing 19; the inner side of the L-shaped plate is provided with a rubber pad 20. The rubber pad has elasticity, and the surface friction degree is higher, helps improving the fixed stability of mould, in addition, effectively avoids the clamp plate directly to contact with the mould, avoids the mould to receive wearing and tearing, improves the life of mould.

Specifically, the long bolt is of an integrally formed structure; the pressing plate is of an integrally formed structure. The integrated structure is convenient for batch production, and can increase the mechanical strength of the parts and prolong the service life.

The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited to the embodiments, and any modifications that utilize the inventive concepts are intended to be included within the scope of the appended claims.
