An object of the utility model is to provide an automatic cut mouth of a river structure in mould to solve clout and product separation and mainly adopt artifical manually operation's mode, waste time and energy, and damage the technical problem of product easily.

In order to achieve the above object, the utility model provides a following technical scheme:

automatic mouth of a river structure of cutting in mould, comprising a base plate, the top surface from the bottom up of bottom plate is equipped with the thimble board in proper order and ends the faller, the top that ends the faller is equipped with the lower bolster, the middle part of lower bolster is equipped with row cinder hole, the bilateral symmetry in row cinder hole is equipped with into the die cavity, arrange through the runner intercommunication between cinder hole and the die cavity, the die cavity inlays and is equipped with the truncation piece near the position department of runner, the bottom of truncation piece is passed the lower bolster and is connected fixedly with ending the faller, the bottom surface department that the lower bolster corresponds into the die cavity is equipped with the thimble, the bottom of thimble is passed the spring and is ended faller fixed connection, arrange the downthehole row sediment needle that is equipped with of sediment, the bottom of arranging the sediment needle passes the lower bolster and ends faller fixed connection.

Furthermore, the top end of the cutting block is flush with the top surface of the lower template, an arc groove is formed in the top end of the cutting block, and the arc groove is matched with the flow channel.

Furthermore, the cross section of the cutting block is trapezoidal.

Furthermore, a guide rod is arranged on the needle stop plate, is positioned on the inner side of the spring and is shorter than the spring.

Furthermore, the top end of the slag discharging needle is positioned at the lower part of the inner side of the slag discharging hole.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, set up the block of cutting off in the exit of runner, the effort of drawing of patterns is at first used in the junction of runner and shaping chamber behind the die sinking for get rid of the clout, later along with the increase of effort, the thimble is ejecting with the product gradually, and it is ejecting also with the residual material in the row's cinder hole to arrange the sediment needle, thereby accomplishes deviating from of demolding and residual material.

The excess material at the joint of the runner and the product is cut off before demoulding, so that the discharged material does not need to be manually cut off, the production process is simplified, and the material is saved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to 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 the skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

automatic water gap structure of cutting in mould, comprising a base plate 1, the top surface from the bottom up of bottom plate 1 is equipped with thimble board 2 and ending faller 3 in proper order, the top of ending faller 3 is equipped with lower bolster 4, the middle part of lower bolster 4 is equipped with row cinder hole 5, the bilateral symmetry of row cinder hole 5 is equipped with into die cavity 6, communicate through runner 7 between row cinder hole 5 and the die cavity 6, die cavity 6 inlays to be equipped with cutting block 8 near runner 7's position department, cutting block 8's bottom is passed lower bolster 4 and is connected fixedly with ending faller 3, the bottom surface department that lower bolster 4 corresponds into die cavity 6 is equipped with thimble 9, spring 10 and ending faller 3 fixed connection are passed to thimble 9's bottom, be equipped with row sediment needle 11 in row cinder hole 5, the bottom of arranging sediment needle 11 passes lower bolster 4 and ends faller 3 fixed connection.

In the scheme, the cut-off block 8 is arranged at the outlet of the flow channel 7, acting force of demolding after mold opening is firstly acted at the joint of the flow channel 7 and the forming cavity 6 and used for removing excess materials, then the ejector pin 9 gradually ejects out a product along with the increase of the acting force, and the residue discharging needle 11 also ejects out residual materials in the residue discharging hole 5, so that mold opening and removal of the residual materials are completed.

Because the excess material at the connecting part of the runner 7 and the product is cut off before demoulding, the discharged material does not need to be manually cut off, thereby simplifying the production process and saving the material.

In one embodiment, the top end of the cut-off block 8 is flush with the top surface of the lower template 4, the top end of the cut-off block 8 is provided with an arc groove 12, and the arc groove 12 is matched with the runner 7, so that the cut-off block 8 also forms a part of the runner 7, the circulation of materials is not influenced, and the complete cut-off of the runner 7 can be ensured. Preferably, the thickness of the cutoff block 8 is controlled to be 1-2mm to increase the cutoff force at the cutoff.

In one embodiment, the cross-section of the cutoff block 8 is trapezoidal, so that the position of the cutoff block 8 is limited when sliding on the lower die plate 4, thereby ensuring the dimensional accuracy of the molding cavity 6.

In one embodiment, the needle stop plate 3 is provided with a guide rod 13, the guide rod 13 is positioned inside the spring 10, the length of the guide rod 13 is smaller than that of the spring 10, and the position of the spring 10 is limited through the guide rod 13 so as to avoid inclination of the spring 10 during compression.
