Description

Mold flipping and mold opening and closing structure

technical field

The utility model relates to the field of food machinery, in particular to a mold turning and opening and closing structure.

Background technique

At present, in the traditional pouring molding operation, because the finished product needs a long molding time for solidification and foaming molding, therefore, a whole set of mold equipment must be arranged and transported by crawler belts or similar operation methods, and the pouring and blanking structure is fixed on the machine. On the top of the table, the pouring operation is carried out by continuous and cyclic shifting of the mold.

After the material is injected into the cavity of the mold, it must be heated for foaming operation, and the mold must be turned over at an appropriate time to make the heat distribution even, so that the foaming molding can fill the entire cavity, ensuring that the appearance of the finished product is complete and there is no lack of material. Good product; however, according to the current mechanical operation method, the flipping of the mold is still carried out manually. However, this kind of operation method is not only unscientific, but also the flipping time is different, and the product will still have defects due to uneven heating; on the other hand, the mold Bulky and high temperature, manual turning is very labor-intensive and time-consuming, and accidents such as burns are prone to occur; in addition to turning over the mold, there is still a mold to open for injection, then close the mold for cyclic shifting, and then open the mold to take out the product after heating Due to the fact that the mold will accumulate a considerable amount of heat during the continuous heating cycle, manual operation is even more dangerous; obviously, if the above-mentioned dangerous operations can be carried out with full mechanical automation, it will be the only and urgent task .

In view of this, the creator of this utility model has developed a number of patented structures for this subject to solve the problem of automatic flipping and heating of the mold; now, he will further study this subject and develop the utility model "mold turning and opening and closing model device".

Detailed ways

Please refer to Fig. 1, it is the disposition drawing of mold turning and opening and closing mold structure of the present utility model on machine platform, and it comprises:

The mold closing structure 1, as shown in Figure 5, is provided with an extension arm 10 and the arm body is pivotally connected to the installation position of the machine table 5, and its end is pivotally connected to the arm end of the telescopic cylinder 11;

A telescopic arm 12 is combined at the other end of the extension arm 10, and a stop pin 120 is combined at its open end;

The mold turning structure 2, as shown in Fig. 7 and Fig. 8, includes two opposite rotary discs 20, which are provided with a crossing channel 21 at a moderate position on the opposite surface; arc dike 22;

The turntable 20 can be rotated by an external power structure 23, the external power structure 23 can be a motor, or a row rack 24 linked by a telescopic cylinder 25 is provided at the installation position of the machine table 5, and It is relatively meshed with the coaxial gear 200 of the rotary table 20;

The mold opening structure 3, as shown in Figure 11, is provided with an extension arm 30 and the arm body is pivotally connected to the installation position of the machine platform 5, and its end is pivotally connected to the arm end of the telescopic cylinder 31;

A telescopic arm 32 is combined at the other end of the extension arm 30, and a stop pin 33 is combined at its open end;

And the mold 4 mentioned, its structure is shown in Fig. 2, Fig. 3, Fig. 4A and Fig. 4B. A guide rod 42 is arranged horizontally;

A fixed body 43 is installed at the flipping end of the lower bottom mold 41, which can preferably be a bolt; A positioning body 400 is provided (refer to FIG. 3 );

And on the surface side of the upper lifting mold 40, a combination hole 401 is provided;

Therefore, after the above-mentioned structure of the utility model is installed on the machine platform 5, the mold can be transported to complete the automatic mold opening and closing and turning procedures with the cooperation of the conveying structure:

The mold 4 is in the mold opening state, that is, the mold 40 is lifted up, and after passing through the injection zone 6, it is injected into the mold cavity and continues to move forward;

After positioning in front of the closed mold structure, the extension arm 10 is stretched out and combined with the joint hole 401 of the lifting mold 40 on the mold 4 by means of the stop pin 120 at the front end of the telescopic arm 12, and pushed by the telescopic cylinder 11 by the end of the extension arm 10 And move back to the positioning, and the upper lifting mold 40 is closed in conjunction with it;

Please refer to Fig. 6, when the mold 4 passes the first gradually expanding body 7 installed on the outside position of its fixing body 43 of the mold 4 close to the machine table 5, its fixing body 43 abuts against the first gradually expanding body 7 to make it move The positioning body 400 can be locked against the positioning body 400 of the upper lifting mold 40 to avoid accidental mold opening by shrinking inwardly;

The mold can continue to be turned over. As shown in FIG. 9, the guide rod 42 at the front and rear ends of the mold 4 penetrates the corresponding two cross-tracks 21 of the rotary disk 20 when it moves forward and is positioned.
