This molding equipment requires a control mechanism independent of the molding mold and its moving mechanism to realize the opening and closing of the mold and the demolding operation of the product therein, which undoubtedly increases the complexity of the equipment structure and increases the difficulty of control.

In this process, it is not necessary to set up any additional operating components outside the cavity mold 1, and the demolding of the finished product W directly depends on the movement of the cavity mold 1. It is only necessary to design the movement path of the cavity mold 1 to match the demolding process of the finished product W, so that while the demolding control device is eliminated and the motion mechanism is simplified, the demolding control can also be eliminated and the control logic can be simplified. This is conducive to optimizing the design and assembly of food molding equipment and improving maintainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. In this specification, the size ratios in the drawings do not represent the actual size ratios, but are only used to reflect the relative position relationship and connection relationship between the components. Components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.
[0035] The utility model provides a cavity mold, which mainly realizes the opening and closing of the mold and the demoulding of the product in the same motion operation through the design of the body and the control of its trajectory. Figure 1 The figure shows a schematic diagram of the structure of the cavity mold bar 11. The cavity mold bar 11 has a plurality of cavities 111 arranged on its front. The cavities 111 are used to hold the raw materials used for molding and provide a space for the raw materials to solidify and mold. The back or end face of the cavity mold bar 11 is provided with a connector 112. The connector 112 is used to chain-connect with adjacent cavity mold bars 11, so that the adjacent cavity mold bars 11 can deflect toward the back side around the connection position in the direction of arrangement and extension, so that the direction of the cavity mold bar 11 can be changed when it moves after connection. The connectors 112 can be directly connected by rotation, or they can be connected by transition components, such as Figure 1 The transmission chain 12 shown in FIG.
[0036] Figure 2 Schematic diagram of the cavity mold 1. The cavity mold bars 11 are connected side by side to form the cavity mold 1. Since the cavity mold bars 11 are chain-connected, the adjacent cavity mold bars 11 can be deflected like the links of a chain, so that the motion trajectory of the cavity mold 1 can be bent when it moves along the extension direction. This is conducive to the realization of automated injection, molding and demoulding operations. Specifically, different functions can be completed in different areas on the trajectory by setting the motion trajectory of the cavity mold 1. In the first position, the upper surface of the cavity mold bar 11 of the cavity mold 1 is in an open state, and the cavity 111 can be injected; after the motion path of the cavity mold 1 changes direction, it enters the second position. In the second position, the closed cavity 111 is solidified and molded. At this time, two-color and two-material molding can also be realized by the opposite and fitting method of the two cavity molds 1. It is only necessary to inject different raw materials into the cavities 111 of the two cavity molds 1 and keep the positions and movements of the cavities 111 on different cavity molds 1 consistent. After the movement path of the cavity mold 1 changes direction again, it enters the third position, and at the third position, the cavity 111 is reopened to achieve demoulding. Figure 2In the embodiment, a technical solution is provided for realizing a chain connection of the cavity mold strips 11 by using a chain to connect the cavity mold strips 11. The cavity mold strips 11 are fixed on the links of the transmission chain 12 in sequence and uniformly. When the chain is running, the cavity mold strips 11 move with the fixed links. In simple terms, a fixing hole can be opened on the end face or the back face of the cavity mold strip 11, and the fixing hole can be sleeved on the axis of the link. Since each link has two axes, the relative position of the cavity mold strip 11 and the link of the transmission chain 12 can be fixed by sleeved on two axes. Other connection methods of using the transmission chain 12 to connect the cavity mold strips 11 are not excluded. For example, the cavity mold strips 11 can be as follows Figure 2 The mold bars 11 may be fixed with one or more chain links spaced apart, or may be closely arranged without chain links spaced apart, or may be fixed across several chain links. The mold bars 11 may also be fixed directly without using the transmission chain 12, for example Figure 3 In the embodiment, the connecting pieces 112 are alternately arranged on both sides of the back side of the cavity mold bar 11 in the moving direction, and the connecting pieces 112 on the opposite sides of the adjacent cavity mold bars 11 are alternately sleeved on the common rotating shaft of the two to achieve relative rotation connection. Generally, the cavity mold 1 can be formed into a ring structure by connecting the cavity mold bars 11 in a chain-like manner as above, so as to achieve cyclic operation under power drive.
[0037] Figure 4 is another embodiment of the cavity mold strip 11. The cavity 111 can be as follows Figure 1 It is arranged on the front surface of the cavity mold bar 11 to form a parting surface located on the front surface. Similarly, it can also be arranged at the front edge of the cavity mold bar 11, and has a cross section on the side to form multiple parting surfaces on the cavity 111. Multiple cavities 111 are arranged on the front side of the cavity mold bar 11. Since they are arranged at the edge of the cavity mold bar 11, a first parting surface facing the front of the cavity mold bar 11 and a second parting surface facing the side of the cavity mold bar 11 are formed. When the cavity mold bars 11 are connected to each other in a chain-like manner to form a cavity mold 1, the cavities 111 of each adjacent cavity mold bar 11 are butted together to form a space for accommodating raw materials and molding. If the cavity mold 1 does not change its direction during operation and only moves in a straight line, the butted cavities 111 are tightly fitted on the second parting surface, and the raw materials can be accommodated and molded in the space formed by the two. Once the movement direction of the cavity mold 1 changes, the adjacent cavity mold strips 11 will deflect to the back side to a certain extent, thereby causing the butted cavities 111 to separate at the second parting surface. Figure 4Schematic diagram of . At this time, due to the existence of deflection and separation, the cavity 111 can be separated from the already formed finished product W during the movement to achieve demolding. That is, as the cavity mold 1 operates, the front cavity 111 between adjacent cavities 111 deflects to the back side because the moving direction of the cavity mold 1 has changed. At this time, the rear cavity 111 is still in a fitted state, clamping the finished product W. Under the effects of the above two aspects, the finished product W and the front cavity 111 will separate spontaneously, realizing automatic demolding during the operation of the cavity mold 1.
[0038] In order to increase the density of the mold cavities 111 and the output per unit area, the mold cavities 111 are preferably arranged at the two side edges of the front side of the mold strip 11 along the conveying direction, which can make the mold strip 11 itself have a higher molding density and improve the production efficiency of the molding process. On this basis, the sizes of the mold cavities 111 located at the two side edges of the mold strip 11 can be inconsistent. Figure 5 As shown in FIG. 1 , the projection area of the cavity 111 on one side on the front of the cavity mold bar 11 is smaller than the projection area of the cavity 111 on the other side on the front of the cavity mold bar 11. When the cavity mold bars 11 are chain-connected to form a cavity mold 1, if the cavity mold bar 11 moves in the direction of movement, the side where the cavity 111 with a larger projection area is located is at the rear. At this time, as the cavity mold 1 moves in the direction of movement, the cavity 111 with a larger projection area is located at the rear. Figure 4 As shown, the mold strip 11 of the front cavity is deflected and separated from the finished product W. The cavity 111 that is separated from the finished product W first is the cavity 111 with a larger projection area. Therefore, a larger range of separation between the cavity 111 and the finished product W can be achieved, leaving only the cavity 111 with a smaller projection area to be combined with the finished product W. This can facilitate the spontaneous demolding between the cavity 111 with a smaller projection area and the finished product W in the absence of a peeling force. Of course, from the perspective of effectiveness, the area of the cavity 111 with a smaller projection area cannot be too small, otherwise it may be difficult to clamp the product when the cavity 111 with a larger projection area is demolded first. In experience, the smaller projection area should not be less than 1 / 4 of the area of the cavity 111, and the ratio of the areas on both sides is 1 / 3. The smaller projection area is preferably not less than 1 / 3 of the area of the cavity 111 to meet the requirements of different hardness of the finished product W.
[0039] based on Figure 4 The technical direction of the cavity mold strip 11 does not exclude the following Figure 6The embodiment shown. That is, the cavity 111 is only set on one side of the front surface of the cavity mold bar 11, so that the cavity 111 forms a cross section on the side of the side as the second parting surface. At this time, it is usually necessary to group the cavity mold bars 11 constituting the cavity mold 1 in sequence in pairs to obtain a cavity mold group 13 arranged in sequence on the cavity mold 1 along the moving direction. The two cavity mold bars 11 belonging to the cavity mold group 13 can only have cavities 111 on the opposite edges of their front faces, so that the second parting surface between the corresponding cavities 111 can be opened and closed within the group to complete molding and demolding operations. There is a reason why the cavity 111 is not opened on both sides of the cavity mold bar 11. Mainly, through the design of appropriate transmission components, when the cavity mold 1 moves, the cavity mold group 13 responds in different working modes corresponding to a specific guide component. Specifically, during demolding, the cavity mold bars 11 operate independently, and each cavity mold bar 11 opens and closes independently, so that the cavity mold bars 11 in the cavity mold group 13 are opened from the fitted state, and the finished product W is easily demolded. During injection, the two cavity mold bars 11 in the cavity mold group 13 are fitted in advance, and the two move as a relatively static whole. During injection, the raw material is only distributed in the cavity 111, and will not enter the side walls of the two cavities 111 that are tightly fitted, thereby avoiding the problems of material clamping and loose closure, and can also reduce the problems of finished product flash caused by material clamping under this process.
[0040] For the cavity mold 1 composed of the cavity mold strips 11, during the injection process, the raw material released to the front of the cavity mold strips 11 will not only enter the cavity 111, but also remain on the front surface of the cavity 111, and thus may enter the side space when the adjacent cavity mold strips 11 deflect each other and open the side space between the two. If there is no suitable side profile design, this will cause the raw material to leak out from the side space. This can be compensated by setting a material receiving and recovery device at the leakage point, but it is obviously not the optimal solution. Therefore, it is necessary to reasonably design the cross-sectional profile of the side of the cavity mold strips 11, so that during the operation of the cavity mold 1, no matter how the adjacent cavity mold strips 11 deflect, the side walls between the cavity mold strips 11 can always maintain a relative contact state, maintain the relative closure of the gap between the side walls, avoid the generation of a leakage gap, and thus avoid the raw material from leaking from the gap between the two.
[0041] For the cavity mold strips 11 with different axis settings, for example Figure 1 or Figure 4 In the embodiments shown in FIG. 1 , this function can be achieved by reasonably setting the side bottom edge profile of the cavity mold strip 11. Figure 7 as well as Figure 8The cavity mold strip 11 has arc transitions 11A at the bottom edges of both sides, the center of the arc transition 11A is coaxial with the relatively close rotation axis of the cavity mold strip 11 on the corresponding side, and the sum of the radii r1 and r2 of the arc transitions 11A on both sides of the same gap should be equal to the rotation axis distance L of the gap. Of course, in general, considering the convenience of manufacturing and the problem of foolproof assembly, r1=r2=L can be directly applied. Figure 8 Essentially, it is applicable to the case where the cavity mold bars 11 are at least one link apart, where L is the product of the pitch and the number of intermediate chain links. Figure 6 According to the technical solution in, the above-mentioned improvement can be made only on the side wall relatively far away from the two cavity mold bars 11 of the cavity mold group 13, that is, the bottom edge of the side wall close to the outside that contacts the cavity mold bars 11 of the other cavity mold group 13 can be set to an arc transition to achieve the above-mentioned purpose.
[0042] If there is no transition link, the above problem can still be solved. Similar solutions can be found in Figure 3 as well as Fig. 9 When there is no transition link, the cavity mold bars 11 share the same rotation axis, which is achieved by arranging the connecting members 112 at alternating intervals, such as Figure 3 As shown. At this time, in order to achieve the contact between the side faces of the cavity mold strip 11 and close the side gap, it is only necessary to ensure that the connector 112 and the corresponding side face of the other cavity mold strip 11 are continuously closed by line contact or surface contact. For example, the outer arc surface of the connector 112 is closed with the tangent plane of the cavity mold strip 11, or the inner arc surface made on the cavity mold strip 11 is closed. Generally, we prefer to use the outer arc surface of the connector 112 to close the gap with the concentric and equal-diameter inner arc surface machined on the surface of the adjacent cavity mold strip 11. It can also be achieved by the outer arc surface of the connector 112 and the linear edge on the side that fits the outer arc surface. This can remove the space that may exist in the gap and prevent the raw material from remaining in the gap.
[0043] like Fig.10Shown is a schematic diagram of a further embodiment of the cavity mold bar 11. In some cases, it is also necessary to evaporate the water in the raw material during the process of raw material molding and curing. In order to quickly achieve the above purpose, an air vent 11H that passes through the cavity 111 and the back of the cavity mold bar 11 can be opened on the cavity mold bar 11. During the molding process after the cavity mold bar 11 is bonded, the cavity 111 is closed, and the water in the raw material is difficult to dissipate during the molding process, and thus difficult to solidify. The air vent 11H can accelerate the process by accelerating the evaporation of water. The diameter of the air vent 11H is small, and the raw material generally does not enter the cavity mold bar 11. Therefore, the air vent 11H will not affect the demolding of the finished product W, and will not be blocked. Of course, even if the air vent 11H may be blocked by the raw material, it can also be dredged by a dredging mechanism set at other positions on the movement path of the cavity mold 1.
[0044] The above content is only a description of the preferred implementation mode of the utility model, and does not limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements made to the technical solution of the utility model by ordinary technicians in this field should fall within the protection scope determined by the claims of the utility model.
