[0032] See also Figures 1 to 10 The utility model provides a mold structure 100, which can improve the mold closing and demolding efficiency between the main mold 110 and the movable block mold 120 by improving the connection method between the main mold 110 and the movable block mold 120, thereby improving the production efficiency of the product corresponding to the mold structure 100.

[0033] See also Figures 1 to 5 , further describe the mold structure 100. The mold structure 100 includes a main mold 110, a movable mold 120, a positioning assembly 130 and a connecting assembly 140. A support portion 111 is provided on the main mold 110, and the support portion 111 can be integrally formed and connected with the main mold 110, or can be fixedly connected to the surface of the main mold 110 by fasteners such as bolts. The support portion 111 can be a plane structure, a curved surface structure, or a combination of concave and convex shapes, etc., depending on the support and connection requirements of the support portion 111. Preferably, in this embodiment, the support portion 111 is a nearly flat plate structure, which has a simple shape and is easy to form. The movable mold 120 is arranged on the support portion 111, and has a first state of being fitted with the support portion 111 and a second state of being separated from the support portion 111. The movable mold 120 has an abutment portion 121 on one side facing the support portion 111, and when the movable mold 120 is in the first state, the abutment portion 121 abuts against the support portion 111. When the movable block mold 120 is in the second state, the abutment portion 121 is separated from the support portion 111. The abutment portion 121 may be an arc-shaped plate structure or a flat plate structure. Preferably, in this embodiment, the abutment portion 121 is a flat plate structure corresponding to the support portion 111, so that a larger and more stable contact plane can be formed with the support portion 111, which is conducive to improving the stability of the fitting contact between the movable block mold 120 and the main body mold 110 in the first state.

[0034] It should be noted that the specific material of the main mold 110 and the movable block mold 120 is not limited, for example, it can be a combination of ABS board and aluminum profile, or it can be a nylon board processed part, etc., which needs to be determined according to actual production requirements. The materials of the main mold 110 and the movable block mold 120 can be the same or different. In this embodiment, the main mold 110 and the movable block mold 120 are made of the same material and are both made of glass fiber cloth and resin materials, etc., which are laminated and wound and then compacted. The specific shapes of the main mold 110 and the movable block mold 120 are also not limited, and are subject to meeting the molding requirements of the product.

[0035] The positioning assembly 130 includes a positioning pin 131 and a pin seat 132. The pin seat 132 is arranged on the support part 111, and a pin hole 1321 is opened on the pin seat 132. The pin seat 132 can be partially embedded in the support part 111 to achieve a fixed connection with the support part 111, or can be fixedly connected to the support part 111 by fasteners such as bolts. As long as the connection strength between the pin seat 132 and the support part 111 is guaranteed, there is no specific limitation on this. Preferably, in this embodiment, the pin seat 132 is partially embedded in the main mold 110 during the manufacturing process of the main mold 110 to achieve a fixed connection between the pin seat 132 and the main mold 110. In this way, the connection between the pin seat 132 and the support part 111 can be more firm and reliable, reducing the probability of the pin seat 132 falling off from the main mold 110 during use. The positioning pin 131 is arranged on the movable block mold 120, and the positioning pin 131 cooperates with the pin hole 1321. The positioning pin 131 is fixedly connected to the abutment portion 121, and the fixed connection method can be a snap connection or an embedded connection, etc., as long as the connection between the positioning pin 131 and the abutment portion 121 is stable and reliable. Preferably, in this embodiment, the positioning pin 131 is at least partially embedded in the interior of the abutment portion 121 during the manufacturing process of the movable block mold 120, thereby realizing the connection between the positioning pin 131 and the abutment portion 121.

[0036] In other embodiments, the positioning pin 131 may be disposed on the supporting portion 111 of the main mold 110 , and the pin seat 132 may be correspondingly disposed on the abutting portion 121 of the movable block mold 120 , and the positioning pin 131 may cooperate with the pin hole 1321 disposed on the pin seat 132 .

[0037] The connecting assembly 140 includes a magnetic member 141 and a magnetic conductive member 142. The magnetic member 141 is arranged on the support portion 111, and the magnetic conductive member 142 is arranged on the movable block mold 120. The magnetic member 141 can be an ordinary magnet member or an electromagnet. The material of the magnetic conductive member 142 can be any material that can produce a good magnetic attraction effect with the magnetic member 141, such as a cast iron member, a carbon steel member, etc. Preferably, in the present embodiment, the magnetic member 141 is an ordinary magnet block, and the magnetic conductive member 142 is a cast iron member. On the premise of meeting the requirements for the size of the attraction force between the movable block mold 120 and the main mold 110, the magnetic member 141 can be provided with one or more, and there is no limitation on this. Preferably, a plurality of magnetic members 141 are provided, and the plurality of magnetic members 141 are dispersedly arranged on the surface of the support portion 111 facing the abutment portion 121. Correspondingly, there are also multiple magnetic conductive parts 142, and one magnetic conductive part 142 corresponds to one magnetic part 141, and multiple magnetic conductive parts 142 are dispersedly arranged on the surface of the abutment portion 121 facing the support portion 111. The specific structural shapes of the magnetic parts 141 and the magnetic conductive parts 142 are not limited, for example, they can be rectangular parallelepiped, cube or cylinder. It should be noted that in other embodiments, the magnetic part 141 can also be arranged on the movable block mold 120, and the magnetic conductive part 142 can be arranged on the main body mold 110. When the movable block mold 120 is in the first state, that is, when the movable block mold 120 and the main mold 110 are molded together, the positioning pin 131 is inserted into the pin hole 1321, and the magnetic part 141 and the magnetic conductive part 142 are attracted to each other; when the movable block mold 120 is in the second state, that is, when the movable block mold 120 and the main mold 110 are demolded, the positioning pin 131 is removed from the pin hole 1321, and the magnetic part 141 and the magnetic conductive part 142 are separated.

[0038] The mold structure 100 provided by the utility model is provided with a magnetic member 141 and a magnetic conductive member 142. When the movable block mold 120 is in a first state, the magnetic member 141 and the magnetic conductive member 142 are attracted to each other; when the movable block mold 120 is in a second state, the magnetic member 141 and the magnetic conductive member 142 are separated from each other. Such a configuration does not require disassembly of fasteners such as bolts. By changing the attraction state between the magnetic member 141 and the magnetic conductive member 142, the fitting and separation between the movable block mold 120 and the main mold 110, that is, the mold closing and demolding operations, can be achieved. Therefore, the mold closing and demolding efficiency between the movable block mold 120 and the main mold 110 can be provided, thereby improving the production efficiency of the product corresponding to the mold structure 100. At the same time, because a positioning pin 131 and a pin seat 132 are provided, the positioning pin 131 cooperates with the pin hole 1321 of the pin seat 132, which can play a positioning role in the mold closing process between the movable block mold 120 and the main mold 110, thereby improving the mold closing accuracy between the movable block mold 120 and the main mold 110, and then improving the molding accuracy of the product.

[0039] See also Figure 2 , Figure 4 and Fig. 9 In an example of the mold structure 100 of the utility model, the positioning pin 131 includes a pin body 1311, and the pin body 1311 penetrates the thickness of the abutment portion 121, and at least partially protrudes to the side of the abutment portion 121 facing the support portion 111. Along the axial direction of the pin body 1311, the pin body 1311 includes a matching portion 1316 and a guide portion 1312 that are connected to each other, and the guide portion 1312 is located at one end of the matching portion 1316 close to the support portion 111. There are many specific structures of the guide portion 1312. For example, the guide portion 1312 can be a frustum structure or a pyramid structure. As long as the cross-section of the guide portion 1312 away from the matching portion 1316 is smaller than the cross-section of the matching portion 1316, it can play a guiding role when the pin body 1311 enters the pin hole 1321. Preferably, in this embodiment, the guide portion 1312 is a frustum structure coaxially arranged with the matching portion 1316. By providing the guide portion 1312 , during the mold closing process between the movable block mold 120 and the main mold 110 , the guide portion 1312 can guide the positioning pin 131 to be quickly inserted into the pin hole 1321 , thereby increasing the mold closing speed between the movable block mold 120 and the main mold 110 .

[0040] See also Figure 2 , Figure 4 and Fig. 9 In one example of the mold structure 100 of the present utility model, along the axial direction of the positioning pin 131 (such as Fig. 9 The positioning pin 131 further includes a boss portion 1313, the boss portion 1313 is connected to the end of the matching portion 1316 away from the guide portion 1312, the boss portion 1313 and the matching portion 1316 can be integrally formed, or can be welded or any other fixed connection method. Preferably, in this embodiment, the boss portion 1313 and the matching portion 1316 are integrally formed. The boss portion 1313 can be coaxially arranged with the matching portion 1316, or can be non-coaxially arranged, as long as it is ensured that the boss portion 1313 at least partially protrudes to the radial outer side of the matching portion 1316. The abutting portion 121 is provided with a step hole 1211 matching the boss portion 1313, and the opening of the step hole 1211 faces the side of the abutting portion 121 away from the support portion 111. The boss portion 1313 is accommodated in the stepped hole 1211, and the stepped surface of the stepped hole 1211 abuts against the end surface of the boss portion 1313 on the side facing the matching portion 1316. The arrangement of the boss portion 1313 can play an axial positioning role in the connection between the positioning pin 131 and the abutting portion 121, thereby reducing the probability of the positioning pin 131 coming off the abutting portion 121 when the movable block mold 120 is demolded from the main mold 110.

[0041] See also Figure 2 , Figure 4 and Fig. 9In an example of the mold structure 100 of the utility model, the positioning pin 131 also includes a stopper 1314, and the stopper 1314 is arranged on the outer periphery of the boss portion 1313, and the stopper 1314 is at least partially connected to the abutment portion 121. The stopper 1314 can be a circular ring structure arranged around the outer periphery of the boss portion 1313, or a plurality of block structures arranged at intervals on the outer periphery of the boss portion 1313. Preferably, in this embodiment, the stopper 1314 is a block structure arranged at intervals on the outer periphery of the boss portion 1313. The connection method between the stopper 1314 and the abutment portion 121 is not limited, for example, the stopper 1314 can be partially or completely embedded in the interior of the abutment portion 121, so that a fixed connection is formed between the stopper 1314 and the abutment portion 121; or the stopper 1314 can be fixedly connected to the surface of the abutment portion 121 by mechanical means such as bolt connection, etc. Preferably, in order to facilitate the connection between the stopper 1314 and the abutment 121, in the present embodiment, during the manufacturing process of the movable block mold 120, part of the stopper 1314 is embedded into the interior of the abutment 121, and then the stopper 1314 and the abutment 121 are fixedly connected together after the movable block mold 120 is formed. By providing the stopper 1314 on the periphery of the boss portion 1313 and fixing the stopper 1314 and the abutment 121, the fixed connection between the positioning pin 131 and the abutment 121 can be achieved, and when the movable block mold 120 is demolded from the main body mold 110, the probability of the positioning pin 131 coming off the movable block mold 120 is further reduced.

[0042] See also Figure 2 , Figure 4 and Fig. 9 In an example of the mold structure 100 of the utility model, the stopper 1314 includes two handles 1315 symmetrically arranged on the outer periphery of the boss 1313, and an arc-shaped contact surface is formed between the handles 1315 and the abutment 121. The specific shape of the handle 1315 is not limited, for example, it can be an approximately hemispherical structure, or an approximately cylindrical structure, etc., as long as the outer surface of the handle 1315 is at least partially an arc-shaped structure, and can form an arc-shaped contact surface when in contact with the abutment 121. Such a setting can reduce the stress concentration phenomenon generated at the connection position of the abutment 121 with the stopper 1314, and further reduce the cracking phenomenon when the abutment 121 is subjected to force, thereby correspondingly improving the service life of the movable block mold 120. Preferably, in this embodiment, the handle 1315 is a cylindrical structure, and the axis of the handle 1315 is consistent with the radial direction of the boss 1313. The shape of the handle 1315 of this structure is convenient for processing and manufacturing, and can save the manufacturing cost of the positioning pin 131.

[0043] See also Figure 2 , Figure 4 , Fig. 9 and Fig.10In an example of the mold structure 100 of the utility model, the support portion 111 is provided with a through hole 1111 that runs through the thickness direction, and the pin seat 132 at least partially extends into the through hole 1111. Along the axial direction of the through hole 1111, one end of the pin seat 132 extends into the through hole 1111, and the pin seat 132 may completely penetrate the through hole 1111, that is, on the side of the support portion 111 facing the abutment portion 121, the end surface of the pin seat 132 is flush with the surface of the support portion 111 or extends to the surface of the support portion 111. The pin seat 132 may also partially extend into the through hole 1111, that is, on the side of the support portion 111 facing the abutment portion 121, the end surface of the pin seat 132 is located inside the through hole 1111. This arrangement, on the one hand, allows the pin seat 132 to be partially embedded in the through hole 1111, increasing the connection strength between the pin seat 132 and the support portion 111, and on the other hand, can reduce the damage caused to the wall of the through hole 1111 by the positioning pin 131 when the positioning pin 131 extends into the pin hole 1321, thereby facilitating the protection of the structural integrity of the main mold 110. Preferably, in this embodiment, along the axial direction of the through hole 1111, on the side of the support portion 111 facing the abutment portion 121, the end face of the pin seat 132 is flush with the surface of the support portion 111. This can facilitate the installation and positioning of the pin seat 132 on the support portion 111, and produce a better protection effect on the wall of the through hole 1111.

[0044] See also Figure 4 and Fig. 9In an example of the mold structure 100 of the utility model, the pin seat 132 includes a pin seat body 1322 and a positioning portion 1323 arranged around the outer periphery of the pin seat body 1322, and the positioning portion 1323 is at least partially in contact with the side of the support portion 111 away from the movable block mold 120. The pin seat body 1322 can be a cylindrical structure, or a square structure, etc. Preferably, in order to facilitate the molding process of the pin seat body 1322, in this embodiment, the pin seat body 1322 is an approximately cylindrical structure. The pin hole 1321 is provided on the pin seat body 1322, and the pin hole 1321 is coaxially arranged with the pin seat 132. The pin hole 1321 can be a through hole 1111 that passes through the pin seat 132, or it can be a blind hole that does not pass through the pin seat 132, as long as it meets the requirements for matching the shaft hole between the positioning pin 131. Preferably, in the present embodiment, the pin hole 1321 is a blind hole structure. This arrangement can reduce the probability of large particles of impurities entering the pin hole 1321 and causing contamination to the inner surface of the pin hole 1321 during the mold manufacturing process or the product molding process, thereby better ensuring the matching relationship between the positioning pin 131 and the pin hole 1321. The positioning portion 1323 can be an annular body arranged around the outer periphery of the pin seat body 1322, or a plurality of block bodies arranged at intervals around the outer periphery of the pin seat body 1322, and no specific limitation is made to this. Preferably, in the present embodiment, the positioning portion 1323 is two cylindrical protrusions symmetrically arranged on the outer periphery of the pin seat body 1322. This arrangement can facilitate the removal and placement of the pin seat 132 during installation. The positioning portion 1323 is in contact with the side of the support portion 111 away from the movable block mold 120, which may refer to that the positioning portion 1323 is partially embedded in the interior of the support portion 111 and forms a fixed connection with the support portion 111, thereby forming an abutting relationship between the positioning portion 1323 and the support portion 111; or the positioning portion 1323 is only in contact with and abuts with the side of the support portion 111 away from the movable block mold 120, and there is no fixed connection between them, etc. Any other manner that satisfies the abutting connection. By providing the positioning portion 1323 and making the positioning portion 1323 at least partially abut against the side of the support portion 111 away from the movable block mold 120, the connection strength between the pin seat 132 and the support portion 111 can be increased, and the probability of the pin seat 132 being displaced during the insertion process of the pin seat 132 and the positioning pin 131 can be reduced, thereby improving the matching accuracy between the positioning pin 131 and the pin seat 132, and improving the mold closing accuracy between the movable block mold 120 and the main mold 110.

[0045] The mold structure of the utility model is provided with a magnetic part and a magnetic conductive part. When the movable block mold is in the first state, the magnetic part and the magnetic conductive part are attracted to each other; when the movable block mold is in the second state, the magnetic part and the magnetic conductive part are separated. In this way, it is not necessary to disassemble and assemble fasteners such as bolts. By changing the attraction state between the magnetic part and the magnetic conductive part, the fitting and separation between the movable block mold and the main mold, that is, the mold closing and demolding operation, can be realized. Therefore, the mold closing and demolding efficiency between the movable block mold and the main mold can be improved, so that the production efficiency of the product corresponding to the mold structure can be significantly improved. At the same time, because a positioning pin and a pin seat are provided, the positioning pin cooperates with the pin hole of the pin seat, so that the mold closing process between the movable block mold and the main mold can be positioned, so that the mold closing accuracy between the movable block mold and the main mold can be improved, and then the molding accuracy of the product can be improved. Therefore, the utility model effectively overcomes some practical problems in the prior art and has a high utilization value and use significance. The above embodiments are only illustrative of the principle and effect of the utility model, and are not used to limit the utility model. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
