[0030] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned 90 degrees or in other orientations in other different ways, and the spatial relative description used herein is interpreted accordingly.

[0033] As Figures 1 to 3 shown, the embodiment one of the present application provides a combined mold, the combined mold at least includes superimposed first module 11, second module 12 and third module 13, the combined mold includes opening and closing assembly 20, the opening and closing assembly 20 includes first locking structure 21, second locking structure 22 and driving structure 23, the first locking structure 21 is fixedly arranged in the third module 13, the second locking structure 22 is slidably arranged in the second module 12, the driving structure 23 is connected with the first module 11;When the driving structure 23 is locked with the first locking structure 21, the first locking structure 21 is unlocked with the second locking structure 22, the second module 12 and the third module 13 are in the unlocked state;When the driving structure 23 is unlocked with the first locking structure 21, the first locking structure 21 is locked with the second locking structure 22, the second module 12 and the third module 13 are in the locked state. The components of the opening and closing assembly 20 are arranged in the interior of the mold, the locking and unlocking of the opening and closing assembly 20 are realized through the opening and closing process of the mold itself, which avoids arranging the opening and closing assembly 20 on the side of the mold, which leads to the situation that the opening and closing assembly 20 is easy to be stuck when the volume of the mold increases. The present application effectively solves the problem that the volume of the mold gradually increases in the prior art, which leads to uneven force of the opening and closing mechanism and the problem that the opening and closing mechanism is easy to be stuck.

[0034] It should be noted that the opening sequence of the combined mold is that the first module 11 is separated from the second module 12, and the second module 12 is separated from the third module 13. When opening, the driving structure 23 is locked with the second locking structure 22 under the action of the first module 11, at this time the first locking structure 21 is unlocked with the second locking structure 22, so that the second module 12 is unlocked with the third module 13. After the second locking structure 22 is locked with the driving structure 23, the second module 12 can be driven away from the third module 13 by the first module 11, and the accurate opening sequence is realized when opening. When closing, the driving structure 23 drives the second module 12 to approach the third module 13 through the locked second locking structure 22, and after the second module 12 contacts the third module 13, the driving structure 23 is unlocked with the second locking structure 22, the second locking structure 22 is locked with the first locking structure 21, and the second module 12 is fixed with the third module 13. At this time, when the first module 11 moves relative to the second module 12, the position of the second module 12 is fixed, so as to realize the closing of the first module 11, that is, to realize the sequence of combining the second module 12 with the third module 13 first, and then combining the second module 12 with the first module 11. Through the mutual cooperation of the driving structure 23, the second locking structure 22 and the first locking structure 21, the strict control of the opening and closing sequence is beneficial to the machining and production of the mold. In an optional embodiment, the opening and closing assembly 20 can be provided as multiple, and in a relatively large mold, multiple opening and closing assemblies 20 can make the opening and closing process more stable. Specifically, four opening and closing assemblies 20 can be provided, which are located at the opposite two sides inside the mold. The two opening and closing assemblies 20 on the same side are away from each other, and the setting directions of the first locking structure 21, the second locking structure 22 and the driving structure 23 are opposite. The purpose of such setting is to balance the forces generated by the opening and closing assemblies 20 during the opening and closing process, which is more beneficial to the stability of the opening and closing, and the opening and closing assembly 20 has a certain supporting function. Such setting can increase the balance of each module during the opening and closing process, which is beneficial to prolong the service life of the mold.

[0035] As Figure 2 , Figure 5 , Figure 7 and Figure 8As shown in the technical scheme of the first embodiment, the second module 12 is provided with a mounting groove 121 and a first through hole 122, the first locking structure 21 is slidably arranged in the first through hole 122, the first locking structure 21 is provided with a locking groove 211, the second locking structure 22 is provided with a locking clamping block 221, the locking clamping block 221 is slidably arranged in the mounting groove 121, and the locking clamping block 221 can extend into the locking groove 211 to form locking. The first locking structure 21 is slidably arranged in the first through hole 122, so that the locking groove 211 can pass through the first through hole 122 to be locked with the locking clamping block 221. When the locking clamping block 221 is locked with the locking groove 211, the second module 12 is locked with the third module 13. It should be noted that the mounting groove 121 and the first through hole 122 are respectively arranged to accommodate the second locking structure 22 and the first locking structure 21, so that the first locking structure 21 and the second locking structure 22 are locked without interfering with the second module 12 and the third module 13. In addition, the compact structure of the mounting groove 121 and the first through hole 122 can reduce the mass of the second module 12, thereby reducing the mass of the combined mold, reducing the gravity of the opening and closing assembly 20 during the opening and closing process, and protecting the opening and closing assembly 20 and reducing the possibility of the combined mold being stuck.

[0036] As shown in the technical scheme of the first embodiment, Figure 2 , Figure 5 , Figure 7 and Figure 8 , the driving structure 23 includes a rod body 231, the bottom of the mounting groove 121 is provided with a second through hole 123, the locking clamping block 221 is provided with a third through hole 2211, and the rod body 231 is slidably arranged in the second through hole 123 and the third through hole 2211. The purpose of arranging the second through hole 123 is that when the driving structure 23 is unlocked with the second locking structure 22, the first module 11 continues to approach the second module 12 to complete the mold closing, and the rod body 231 can pass through the second through hole 123 and the third through hole 2211 to enter the third module 13. Such an arrangement can adjust the maximum distance between the first module 11 and the second module 12 during the opening and closing process by adjusting the length of the rod body 231 as needed, so that the mold can be adjusted according to the needs of the product or the product loading and unloading process after the mold is opened and closed. The adjustment method is not limited to adjusting the assembly position of the rod body 231 or replacing the rod body 231 with different lengths.

[0037] As shown in the technical scheme of the first embodiment, Figure 2 , Figure 5 , Figure 7 and Figure 8As shown in the technical scheme of the first embodiment, the rod body 231 is provided with a driving part 232 at the end away from the first module 11, the driving part 232 is slidably arranged in the second through hole 123, one side of the third through hole 2211 is provided with a pushing part 2212 matched with the driving part 232, and the driving part 232 and the pushing part 2212 are matched to adjust the relative position of the locking block 221 and the locking groove 211. The position relationship between the driving part 232 and the pushing part 2212 is adjusted by the rod body 231, so as to adjust the position of the locking block 221 and the locking groove 211, that is, to control the locking relationship between the second module 12 and the third module 13 by the first module 11, so as to accurately control the mold opening and closing sequence. It should be noted that when the pushing part 2212 is arranged on the side away from the first locking structure 21, the pushing part 2212 pushes the driving part 232 during the mold closing, so that the locking block 221 is locked with the locking groove 211; when the pushing part 2212 is arranged on the side close to the first locking structure 21, the driving part 232 pushes the pushing part 2212 during the mold closing, so that the locking block 221 is locked with the locking groove 211.

[0038] As shown in the technical scheme of the first embodiment, Figure 2 , Figure 5 , Figure 7 and Figure 8 , the second locking structure 22 further comprises an elastic member 222, the first end of the elastic member 222 is abutted with the side of the locking block 221 away from the first locking structure 21, and the second end of the elastic member 222 is connected with the side wall of the mounting groove 121. The purpose of arranging the elastic member 222 is to provide a force to the locking block 221, so as to realize the technical effect of the cooperation between the pushing part 2212 and the driving part 232. The elastic member 222 can be selected as a spring and fixed on the side wall of the mounting groove 121, or can be fixed by other components.

[0039] It should be noted that in another optional embodiment, the elastic member 222 can be arranged on the bottom wall of the mounting groove 121, and the end away from the mounting groove 121 is provided with a pushing block with an inclined surface, and the locking block 221 is provided with an inclined surface matched with the inclined surface, the cooperation position of the two inclined surfaces is adjusted by the pushing force of the elastic member 222, so as to adjust the position of the locking block 221 in the horizontal direction, and further adjust the cooperation between the locking block 221 and the locking groove 211.

[0040] As shown in the technical scheme of the first embodiment, Figure 7 and Figure 8As shown, in the technical solution of the embodiment one, the driving part 232 is a first inclined surface, which is inclined to the axis direction along the direction of approaching the first module 11, the abutting part 2212 is a second inclined surface, which is inclined to the axis direction along the direction of approaching the first module 11, and the elastic member 222 applies a pushing force to the locking block 221. Such arrangement makes the abutting part 2212 continuously abut against the driving structure 23, when the abutting position is the rod body 231, the end of the locking block 221 away from the elastic member 222 extends into the locking groove 211, and the locking is achieved. When the mold is opened, the rod body 231 is driven by the first module 11 to move away from the second module 12, the driving part 232 approaches the abutting part 2212, when the two are in contact, the abutting part 2212 is pushed away from the locking groove 211 due to the size of the driving part 232 being larger than that of the rod body 231, and the vertical position is converted into horizontal displacement of the abutting part 2212 through the contact of the inclined surfaces, at this time, the elastic member 222 is compressed, and the pushing force is converted into elastic potential energy and stored. When the mold is closed, the abutting part 2212 pushes the driving part 232 to form locking under the action of the elastic member 222, that is, the second module 12 is hoisted below the first module 11, when the second module 12 is in contact with the third module 13 to complete the mold closing, the first module 11 continues to move downward, the driving part 232 continues to slide downward, and the abutting part 2212 is gradually released, so that the locking block 221 extends into the locking groove 211 to form locking.

[0041] It should be noted that, during the mold closing process, the elastic member 222 continuously applies a pushing force to the locking block 221, which causes the driving part 232 of the driving structure 23 to continuously receive the pushing force, and the arrangement of the inclined surfaces causes the abutting part 2212 to push the driving part 232, and the locking block 221 to extend, after such situation occurs, the end of the locking block 221 close to the first locking structure 21 is prone to interference, which causes the mold closing to fail. In the embodiment one of the present application, the side of the locking block 221 close to the first locking structure 21 is provided with a pushing-back part 2214, the pushing-back part 2214 is an inclined surface, which gradually moves away from the first locking structure 21 along the vertical direction close to the third module 13, and the side of the first locking structure 21 close to the driving structure 23 is provided with a pushing-inclined part 212, the pushing-inclined part 212 is an inclined surface, which gradually moves away from the second locking structure 22 along the vertical direction close to the first module 11, and the two inclined surfaces can cooperate with each other to form abutting, such arrangement causes the pushing-inclined part 212 of the first locking structure 21 to push the locking block 221 during the mold closing of the second module 12, so as to avoid the vertical interference.

[0042] As Figures 2 to 4 and Figure 7 and Figure 8As shown in the technical scheme of Embodiment One, the combined mold further comprises a limiting block 14, which is arranged on one side of the mounting groove 121 close to the first mold block 11, and the limiting block 14 and the bottom of the mounting groove 121 form a limit to the second locking structure 22. The limiting block 14 is arranged to limit the second locking structure 22 inside the mounting groove 121, so that the second locking structure 22 can only move in the horizontal direction, avoiding the second locking structure 22 from moving around, affecting the locking effect, and also easily causing interference. It should be noted that the limiting block 14 is fixedly connected with the second mold block 12 through a fastener, and the limiting block 14 is further provided with a through hole for the sliding of the driving structure 23.

[0043] As shown in the technical scheme of Embodiment One, Figures 2 to 4 and Figure 7 and Figure 8 As shown in the technical scheme of Embodiment One, the side of the mounting groove 121 away from the first locking structure 21 is further provided with a positioning pin 124, the side of the locking block 221 away from the first locking structure 21 is provided with a positioning groove 2213, the positioning pin 124 can partially extend into the positioning groove 2213, and the elastic member 222 is sleeved on the positioning pin 124. The positioning pin 124 is arranged to assemble the elastic member 222, so that the elastic member 222 will not move around and deflect in the setting space, affecting the opening and closing of the mold. The positioning pin 124 can partially extend into the positioning groove 2213, and the positioning groove 2213 forms a limit, which further limits the movement of the locking block 221 in the vertical direction. It should be noted that in an alternative embodiment, the end of the positioning pin 124 is provided with a thread and is threadedly connected with the locking block 221, an installation space is arranged at the end of the mounting groove 121 away from the first locking structure 21, the installation space is communicated with the mounting groove 121 through an opening, the opening can only pass through the rod portion of the positioning pin 124, the larger head portion of the positioning pin 124 is arranged in the installation space, the elastic member 222 is sleeved on the rod portion and abuts against the groove wall between the installation space and the mounting groove 121, and the head portion has a certain displacement space in the installation space, so as to avoid the elastic force of the elastic member 222 being too large, the acting force on the locking block 221 being too large, and the parts being pressed and damaged, and also to limit the acting force of the locking block 221 when extending into the locking groove 211, and to reduce the initial acting force of the driving structure 23 when driving the locking block 221 to drive away from the first locking structure 21.

[0044] As shown in the technical scheme of Embodiment One, Figure 2 and Figure 6As shown, in the technical scheme of the first embodiment, the driving part 232 is provided with a limiting section 233 away from one end of the rod body 231, the third module 13 is provided with a sliding channel 131, the limiting section 233 is in clearance fit with the sliding channel 131, and the size of the limiting section 233 is greater than the size of the second through hole 123. The limiting section 233 is arranged to bear the second module 12 when the second module 12 is separated from the third module 13 after being unlocked, so as to avoid the application of all the force on the driving structure 23 and the second locking structure 22, thereby protecting the use of the two and prolonging the service life thereof.

[0045] It should be noted that the third module 13 is also provided with a mounting part 132 of the first locking structure 21, the first locking structure 21 is fixed in the mounting part 132 by a fastener, and the mounting part 132 is specifically a groove provided on one side of the third module 13 close to the second module 12, and part of the first locking structure 21 is located in the groove. Such an arrangement enables the groove to limit the freedom of the first locking structure 21, and the fastener limits the freedom of the first locking structure 21 in the vertical direction, so that the first locking structure 21 is fixed stably and has the best locking effect. The first module 11 is also provided with a guide structure 30, the guide structure 30 is provided with four corners of a combined mold, specifically a sliding cylindrical shaft body, and corresponding cylindrical through holes are arranged on the second module 12 and the third module 13. Through the cooperation of the cylindrical shaft body and the cylindrical through hole, the movement of the first module 11 and the second module 12 can only be in the vertical direction, so as to avoid large displacement during displacement and thereby damage the opening and closing assembly 20 located therein.

[0046] As Figure 9As shown, the application also provides embodiment two, in the technical scheme of embodiment two, the driving part 232 is a first slope, the first slope is away from the first module 11 along the axis of the rod body 231 direction, to the axis direction tilt, the push part 2212 is a second slope, the second slope is away from the first module 11 along the axis of the rod body 231 direction, to the axis direction tilt, the elastic member 222 applies tension to the locking block 221. The difference from embodiment one is that the push part 2212 pushes the rod body 231 in the mold closing state, the end of the locking block 221 away from the elastic member 222 extends into the locking groove 211, to realize locking. When opening the mold, the rod body 231 is driven away from the second module 12 by the first module 11, the driving part 232 approaches the push part 2212, when the two are in contact, because the size of the driving part 232 is smaller than the size of the rod body 231, that is, the locking of the push part 2212 is contacted, the push part 2212 slides away from the first locking structure 21 under the action of the elastic member 222, and the locking of the locking groove 211 is contacted. When closing the mold, under the action of the elastic member 222, the push part 2212 is in contact with the driving part 232 to form locking, that is, the second module 12 is hoisted below the first module 11, when the second module 12 is in contact with the third module 13 to complete the mold closing, the first module 11 continues to move downward, the driving part 232 is separated from the push part 2212 and continues to slide downward, the push part 2212 is gradually pushed by the rod body 231 to the locking groove 211, and finally the locking block 221 extends into the locking groove 211 to form locking.

[0047] It should be noted that the combined mold provided by embodiment two is the same as embodiment one except for the features described in the embodiment, which will not be repeated here.
