Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing portion of an elastic molding die, and more particularly to a fixing portion of an elastic molding die for solidifying and molding a chocolate material and a molding die mounting member for holding the elastic molding die.

[0002]

2. Description of the Related Art Molds, resin molds and the like used as molding dies for chocolate products cannot be applied to chocolate products having an inverse taper at the time of die cutting, and in molding them, for example, a bag-shaped product made of rubber latex or the like. The use of elastic molds has been developed.

The elastic molds are mounted and fixed one by one between the upper and lower frames as a mold mounting member, and are carried into a continuous production line for chocolate products. As shown in FIG. 4, this fixing mode is, as an example, a molding die mounting member 50 formed by stacking an upper frame 50a and a lower frame 50b having hole openings 51 at six places, and an elastic molding die around the hole openings 51. Wear 40
The upper and lower frames 50a, 50b are provided around the opening peripheral portion 42 of the molding die 40.
(Fig. 5) is clamped and fixed.

In the process of continuously obtaining a decorative product, in order to reliably fill the fluidized chocolate material up to the decorative tip portion 43 of the elastic molding die 40, and to solidify the chocolate product, especially the reverse taper. In order to release the decorative shape 43 including the shape portion from damage so as not to damage it, the elastic molding die 40 is sealed with a cup-shaped container or the like (not shown), and the molding die 40 is negatively pressured to form the molding die 40. Inflated. At this time, if the upper and lower frames 50a and 50b only sandwich the opening peripheral portion 42 of the elastic forming die, the elastic forming die 40 is easily separated from the mounting member 50 due to repeated pulling during expansion, so that the opening peripheral portion 42 is rounded. It is thickened, and this is inserted and fixed in the annular groove 52 provided on the upper surface of the lower frame 52b.

[0005]

However, due to the unstable contraction of the latex rubber during the production of the elastic mold, the unevenness of the rounded peripheral portion 42 due to the rubber thickness, etc., the above-mentioned fixing is troublesome and fixed. There are problems such as lack of certainty.

The present invention has been made to solve these problems, and an object thereof is to provide a fixing portion of an elastic molding die which can easily and surely fix the elastic molding die to a molding die mounting member. is there.

[0007]

The fixing part of the elastic mold of the present invention achieves the above object, and its gist is to fill a fluid chocolate material and solidify it to produce a decorative chocolate. A bag-shaped elastic mold for use in and a mold attachment member composed of an upper frame and a lower frame, which is incorporated into a line for continuously manufacturing decorative chocolate by sandwiching the opening peripheral part of the elastic mold around the hole. In the fixed part of
By installing a recess whose shape and position are the same as those of the ridge around the opening of the elastic molding die on the bottom surface of the upper frame around the hole of the molding die mounting member, the ridge of the elastic molding die is moved upward. It is characterized in that it is adapted to match the concave portion of the frame.

Further, the concave portion of the upper frame of the molding die mounting member can be used as a master of the raised portion of the elastic molding die when the elastic molding die is manufactured.

[0009]

The fixing portion of the elastic molding die according to the present invention has a raised portion provided around the opening of the elastic molding die when the peripheral portion of the opening of the elastic molding die is sandwiched by the upper frame and the lower frame of the molding die mounting member. By completely matching the concave portion provided on the bottom surface of the upper frame around the hole in the mold attachment member, the peeling resistance is increased.

Further, if the raised portion of the elastic molding die is produced by using the concave portion of the upper frame as the original mold, the raised portion which completely fits into the concave portion can be easily produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fixing portion of an elastic mold according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing a mold attachment member 20 that holds a silicone rubber mold 10 that is decorated with animals. In this mounting member 20, an upper frame 20a and a lower frame 20b, which are provided at six places, are stacked on top of each other by taking substantially similar hole openings 21 as an example, and the molding die 10 is individually mounted between them, and a screw or the like (not shown). ) Fix it. It should be noted that members such as pivot pins for attaching to the conveyor provided for the molding die mounting member 20 to move within the manufacturing line and rollers for stabilizing the movement are not shown.

FIG. 2 is a sectional view taken along the line BB of FIG. 1, showing the fixing portion of the molding die of the present invention. The silicone mold 10 has an opening 11 for filling the fluid chocolate material and taking out the cooled and solidified molded product, and as an opening peripheral portion of the mold 10 extending slightly outward from the opening 11. The fixing piece 12 and the annular convex portion 13 as a raised portion which is subsequently raised from the fixed piece 12 are integrally formed. In the present invention, the fixing piece 12 may be omitted and only the annular convex portion 13 may be integrally molded. Upper frame 2 of mold attachment member 20
0a has an annular concave groove 22 as a concave portion installed on the bottom surface 20a 'so as to match the above-mentioned annular convex portion 13. Therefore, the molding die 10 is securely and firmly fixed to the mounting member 20 by the holding force of the upper and lower frames 20a and 20b and the peeling resistance due to the gap-free matching between the annular convex portion 13 and the annular concave groove 22. .

FIG. 3 is a cross-sectional view showing a silicone mold 10 manufactured on the surface of an animal-shaped original mold 30. In the manufacturing stage of the mold 10, an upper frame 20a having an annular groove 22 is formed. If is used as a part of the original die 30 of the molding die 10, the annular convex portion 13 that matches the annular concave groove 22 can be easily manufactured. In this case, first, the upper frame 20a of the mold attachment member 20 is attached to the base 30 'of the original die 30 and the rear surface 20'.
Install a'upward from the hole 21. This mold 10
At the stage of applying the mixed liquid of the silicone rubber and the curing agent to the entire surface of the original mold 30 in the manufacturing process of, the mixed liquid flows down and also penetrates into the annular concave groove 22. Therefore, the groove 22 is subjected to a step of curing the mixed liquid so that the thickness thereof becomes substantially uniform.
It is possible to manufacture the silicone mold 10 having the convex portion 13 that conforms to.

The present invention has been described above by taking an elastic molding die made of silicone rubber as an example. However, as other materials for the molding die, for example, natural rubber latex, urethan-based rubber, synthetic rubber such as butadiene rubber, etc. Can be selected with consideration.

[0015]

As described above, in the fixing portion of the elastic molding die of the present invention, the elastic molding die can be easily and surely fixed to the molding die mounting member, and the durability of the elastic molding die is also improved. Can be improved.
