Abstract
Description
Technical Field
[0001] This application relates to the field of mold technology, and more specifically, to a molding mold and a clamping fixture. Background Technology
[0002] In automated production, it is sometimes necessary to use molding dies to further process semi-finished parts with exposed and covered parts. The covered part is placed in the mold cavity of the molding die. After the material is injected into the mold cavity and shaped, the material injected into the mold cavity forms a molded part that covers the covered part of the semi-finished part. The molded part can provide a certain degree of protection and fixation for the covered part of the semi-finished part.
[0003] Currently, molds typically have receiving holes to accommodate the exposed portions of semi-finished parts. This prevents the material flowing into the mold cavity from contacting the exposed portions, thus keeping them exposed. However, when the exposed portion is elongated, its end can easily abut against the inner wall of the receiving hole during insertion, causing it to bend and deform under stress. This results in a lower yield rate for the molded product. Utility Model Content
[0004] In view of this, this application provides a molding die and a clamping fixture, which can improve the yield of products after molding.
[0005] This application provides a molding die for further molding a semi-finished part having a covered portion and an exposed portion. The molding die includes a first mold body and a second mold body. The first mold body includes a first mold base and a first mold core. The first mold core includes two sub-mold cores, which are slidably connected along a first direction. The two sub-mold cores have mating surfaces that can fit together, wherein at least one sub-mold core has a receiving groove on its mating surface, the receiving groove being configured to receive the exposed portion of the semi-finished part. The first mold core has a closed state, and when the first mold core is in the closed state, the mating surfaces of the two sub-mold cores fit together. The first mold base has a mounting position, which is configured to detachably mount the sub-mold core of the first mold core in the closed state. The second mold body is slidably connected to the first mold base. The second mold body and / or the sub-mold cores have a cavity for receiving the covered portion of the semi-finished part. The sub-mold cores can abut against the second mold body when the second mold body is close to the first mold base, thereby sealing the cavity.
[0006] When using this molding die to process semi-finished parts, the first mold core is first separated from the mounting position. Then, the two sub-mold cores are separated from each other. Next, the exposed part of the semi-finished part is moved from the position between the two mating surfaces to the receiving groove. Then, the two sub-mold cores are brought closer together, so that the first mold core is in a closed state. Then, the closed first mold core is installed in the mounting position. Finally, the first mold base and the second mold body are brought closer together, so that the mold cavity is sealed. Material can then be injected into the mold cavity. After the material in the mold cavity has solidified, the first mold base and the second mold body are separated, the first mold core is separated from the mounting position, and the two sub-mold cores are separated from each other. The processed product can then be removed. When installing the semi-finished part, the mating surfaces of the two sub-mold cores are in a separated state. During the process of moving the exposed part of the semi-finished part to the receiving groove, the semi-finished part can be moved along a direction approximately perpendicular to the length of the exposed part. This reduces the force on the exposed part along its own length, reducing the risk of bending deformation of the exposed part, thereby improving the yield of the processed product.
[0007] In some embodiments of this application, the first mold core further includes a guide member, which includes two guide protrusions. The two guide protrusions are respectively disposed on both sides of the receiving groove and connected to the corresponding sub-mold core. The other sub-mold core is provided with a receiving hole for receiving the guide protrusions. The two guide protrusions have the function of guiding the exposed part into the receiving groove.
[0008] A channel is formed between the two guide protrusions that communicates with the receiving groove. As the exposed part of the semi-finished material moves toward the receiving groove, the two guide protrusions can constrain the movement path of the exposed part so that the exposed part can move precisely into the receiving groove.
[0009] In some embodiments of this application, the sidewalls of the two guide protrusions facing each other are provided with guide surfaces, and the distance between the two guide surfaces gradually increases in the direction away from the corresponding receiving groove along the first direction.
[0010] The guide surface can increase the distance between the two guide protrusions at the part away from the receiving groove, thereby facilitating the movement of the exposed part of the semi-finished material between the two guide protrusions so that the exposed part can be moved into the receiving groove.
[0011] In some embodiments of this application, one of the sub-mold cores is provided with a guide portion extending along a first direction, and the other sub-mold core is provided with an insertion portion. The guide portion is inserted into the insertion portion and slides and engages with the insertion portion along the first direction.
[0012] The sliding fit between the guide part and the insertion part can improve the stability of the sliding between the two sub-mold cores, and at the same time improve the accuracy of the mating surfaces of the two sub-mold cores.
[0013] In some embodiments of this application, the first mold core further includes a connector configured to connect two sub-mold cores when the first mold core is in a closed state, so as to constrain the relative positions of the two sub-mold cores in a first direction.
[0014] The connector links the two sub-mold cores, which can improve the stability of the mating surfaces of the two sub-mold cores to maintain mutual contact, thereby reducing the risk of the semi-finished part falling off when the first mold core moves to the mounting position.
[0015] In some embodiments of this application, the connector includes a limiting rod and a limiting protrusion, which are respectively provided on two sub-mold cores. The limiting rod is provided with a limiting groove, and the limiting protrusion is engaged with the limiting groove when the first mold core is in a closed state.
[0016] The limiting protrusion is inserted into the limiting slot, and the inner wall of the limiting slot can constrain the limiting protrusion, thereby constraining the relative position between the limiting protrusion and the limiting rod, so as to achieve the effect of constraining the relative position between the two sub-mold cores.
[0017] In some embodiments of this application, the connector further includes an elastic element. The limiting protrusion is slidably disposed on the corresponding sub-mold core along the second direction. The elastic element connects the limiting protrusion and the corresponding sub-mold core. The elastic element has an elastic force on the limiting protrusion in the positive direction of the second direction and toward the limiting slot. The second direction intersects the first direction. The limiting protrusion is provided with a first driving surface and a second driving surface on both sides along the first direction. Both the first driving surface and the second driving surface are inclined relative to the first direction. The first driving surface is configured to abut against the limiting rod when the limiting rod moves relative to the limiting protrusion in the positive direction of the first direction, so that the limiting protrusion moves in the opposite direction of the second direction. The second driving surface is configured to abut against the inner wall of the limiting slot when the limiting rod moves relative to the limiting protrusion in the opposite direction of the first direction, so that the limiting protrusion moves in the opposite direction of the second direction.
[0018] When the two sub-mold cores approach each other, the limiting rod moves relative to the limiting protrusion in the positive direction of the first direction, and the first driving surface abuts against the limiting rod, causing the limiting protrusion to move away from the limiting rod in the negative direction of the second direction, so that the limiting rod can continue to move in the first direction; when the limiting protrusion and the limiting slot are aligned in the second direction, the elastic force of the elastic element causes the limiting protrusion to move in the positive direction of the second direction, so that the limiting protrusion can be inserted into the limiting slot; when the two sub-mold cores move away from each other, the limiting rod moves relative to the limiting protrusion in the negative direction of the first direction, and the second driving surface abuts against the inner wall of the limiting slot, causing the limiting protrusion to move away from the limiting rod in the negative direction of the second direction, so that the limiting protrusion can disengage from the limiting slot, so that the limiting rod can continue to move in the negative direction of the second direction.
[0019] In some embodiments of this application, the first mold core further includes a pressure strip, a magnetic element, and an adsorption element. One of the magnetic element and the adsorption element is disposed on the pressure strip, and the other of the magnetic element and the adsorption element is disposed on the sub-mold core. The magnetic element and the adsorption element are magnetically attracted to each other. The pressure strip is configured to clamp the portion of the semi-finished material located outside the mold cavity, respectively, with the sub-mold core.
[0020] The magnetic components attract each other, causing the pressure strip to press against the semi-finished material to fix it in place.
[0021] Embodiments of this application also provide a disassembly fixture, which is used for the first mold core of the molding die provided in any of the above embodiments, wherein the sub-mold core has a mating portion. The disassembly fixture includes a first disassembly member, a second disassembly member, and a disassembly driving member. The first disassembly member has a first connecting portion, which is configured to be inserted into or sleeved on the mating portion of one of the sub-mold cores of the first mold core along a third direction, the third direction intersecting with the first direction; the second disassembly member has a second connecting portion, which is configured to be inserted into or sleeved on the mating portion of another sub-mold core of the first mold core along a third direction; the disassembly driving member connects the first disassembly member and the second disassembly member, and is configured to drive the first disassembly member and the second disassembly member to move away from and towards each other along the first direction.
[0022] Moving the first mold core toward the first and second disassembly members along a third direction allows the mating parts of the two sub-mold cores to connect with the first and second connecting parts respectively. Then, the disassembly drive causes the first and second disassembly members to move away from each other along a first direction, thereby causing the two sub-mold cores to move away from each other, so that the mating surfaces of the two sub-mold cores are separated from each other and remain separated, in order to facilitate the installation of semi-finished parts or the removal of the finished product.
[0023] In some embodiments of this application, the disassembly fixture further includes a fixture base plate, a first positioning block, and a second positioning block; the fixture base plate is provided with a support surface for supporting the sub-mold core, and both the first connecting portion and the second connecting portion protrude from the support surface; the first positioning block is disposed on the fixture base plate and configured to stop the sub-mold core in a fourth direction, and the second positioning block is disposed on the fixture base plate and configured to stop the sub-mold core in a fifth direction, both the fourth and fifth directions are parallel to the support surface, and the fourth and fifth directions intersect.
[0024] The first positioning block and the second positioning block cooperate with each other to constrain the position of the sub-mold core relative to the support surface, so that the mating part and the corresponding first connecting part or second connecting part are aligned in the third direction, thereby facilitating the quick connection of the sub-mold core with the corresponding first disassembly piece or second disassembly piece.

Detailed Implementation
[0037] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0039] The terms “first,” “second,” “third,” “fourth,” and “fifth” used in this article are for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0040] This application provides a molding die for further molding a semi-finished part having a covered portion and an exposed portion. The molding die includes a first mold body and a second mold body. The first mold body includes a first mold base and a first mold core. The first mold core includes two sub-mold cores, which are slidably connected along a first direction. The two sub-mold cores have mating surfaces that can fit together, wherein at least one sub-mold core has a receiving groove on its mating surface, the receiving groove being configured to receive the exposed portion of the semi-finished part. The first mold core has a closed state, and when the first mold core is in the closed state, the mating surfaces of the two sub-mold cores fit together. The first mold base has a mounting position, which is configured to detachably mount the sub-mold core of the first mold core in the closed state. The second mold body is slidably connected to the first mold base. The second mold body and / or the sub-mold cores have a cavity for receiving the covered portion of the semi-finished part. The sub-mold cores can abut against the second mold body when the second mold body is close to the first mold base, thereby sealing the cavity.
[0041] When using this molding die to process semi-finished parts, the first mold core is first separated from the mounting position. Then, the two sub-mold cores are separated from each other. Next, the exposed part of the semi-finished part is moved from the position between the two mating surfaces to the receiving groove. Then, the two sub-mold cores are brought closer together, so that the first mold core is in a closed state. Then, the closed first mold core is installed in the mounting position. Finally, the first mold base and the second mold body are brought closer together, so that the mold cavity is sealed. Material can then be injected into the mold cavity. After the material in the mold cavity has solidified, the first mold base and the second mold body are separated, the first mold core is separated from the mounting position, and the two sub-mold cores are separated from each other. The processed product can then be removed. When installing the semi-finished part, the mating surfaces of the two sub-mold cores are in a separated state. During the process of moving the exposed part of the semi-finished part to the receiving groove, the semi-finished part can be moved along a direction approximately perpendicular to the length of the exposed part. This reduces the force on the exposed part along its own length, reducing the risk of bending deformation of the exposed part, thereby improving the yield of the processed product.
[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0043] Reference Figure 1 and Figure 2This application provides a molding die 1000 for further molding a semi-finished part 2000 having a covered portion 201 and an exposed portion 202. In some embodiments, the semi-finished part 2000 includes a flexible tube 203 and a needle 204, with the needle 204 inserted into one end of the flexible tube 203; the connection between the needle 204 and the flexible tube 203 forms the covered portion 201, and the remaining portion of the needle 204 forms the exposed portion 202. It should be noted that the covered portion 201 refers to the part of the semi-finished part 2000 to be covered.
[0044] The molding die 1000 includes a first mold body 100 and a second mold body 200, which are arranged sequentially along one direction. The first mold body 100 includes a first mold base 11 and a first mold core 12, with the first mold core 12 located on the side of the first mold base 11 facing the second mold body 200. The second mold body 200 includes a second mold base 21 and a second mold core (not shown), with the second mold core located on the side of the second mold base 21 facing the first mold base 11. The second mold base 21 has a guide post 211 extending toward the first mold base 11, and the first mold base 11 has a guide sleeve 111. The guide sleeve 111 and the guide post 211 slide against each other, allowing a sliding connection between the first mold base 11 and the second mold base 21. For ease of description, the relative sliding direction of the first mold base 11 and the second mold base 21 is defined as the mold closing direction H.
[0045] The first mold core 12 and the second mold core each have a mold cavity 121 on their opposite sides. The mold cavity 121 is configured to accommodate the covering portion 201 of the semi-finished material 2000. The first mold core 12 has a receiving hole 122, which communicates with the mold cavity 121 and is configured to accommodate the exposed portion 202 of the semi-finished material 2000. After the semi-finished material 2000 is installed on the first mold core 12, the first mold base 11 and the second mold base 21 are brought close to each other so that the first mold core 12 and the second mold core abut against each other, thus sealing the mold cavity 121. Molten material can then be injected into the mold cavity 121. After the material in the mold cavity 121 has solidified, the material wraps around the outside of the covering portion 201, thus protecting and fixing the covering portion 201. In other embodiments, one of the first mold core 12 and the second mold core is provided with a mold cavity 121, and the other of the first mold core 12 and the second mold core is configured to seal the mold cavity 121 when the two are in contact with each other.
[0046] To reduce the possibility of material leakage from the mold cavity 121 into the receiving hole 122 and contacting the exposed portion 202, after the exposed portion 202 is inserted into the receiving hole 122, the peripheral wall of the exposed portion 202 fits against the inner peripheral wall of the receiving hole 122; exemplarily, the inner diameter of the receiving hole 122 is equal to the outer diameter of the exposed portion 202. During the process of inserting the elongated exposed portion 202 into the receiving hole 122, the end of the exposed portion 202 easily abuts against the inner wall of the receiving hole 122, causing the exposed portion 202 to be subjected to force in its own length direction, resulting in bending deformation of the exposed portion 202, which leads to a low yield of the product obtained after molding the semi-finished material 2000 using the molding die 1000.
[0047] Reference Figure 3 , Figure 4 and Figure 5 The first mold core 12 includes two sub-mold cores 123, which are slidably connected along a first direction X; the first direction X intersects the mold closing direction H. In some embodiments, the first direction X is perpendicular to the mold closing direction H. The two sub-mold cores 123 have mating surfaces 1231 that can fit together, wherein at least one sub-mold core 123 has a receiving groove 1231a on its mating surface 1231; exemplaryly, both sub-mold cores 123 have receiving grooves 1231a on their mating surfaces 1231. The first mold core 12 is in a closed state. When the first mold core 12 is in the closed state, the mating surfaces 1231 of the two sub-mold cores 123 fit together, and the receiving grooves 1231a of the two sub-mold cores 123 together form a receiving hole 122 for receiving the exposed portion 202 of the semi-finished material 2000. In some embodiments, the receiving hole 122 is a cylindrical hole, and the receiving groove 1231a is a semi-cylindrical groove.
[0048] Reference Figure 1 and Figure 4The first mold base 11 has a mounting position 112, which is configured to detachably mount the sub-mold core 123 of the first mold core 12 in a closed state. When installing the semi-finished part 2000, the first mold core 12 can be removed first and the two sub-mold cores 123 can be moved away from each other, so that the mating surfaces 1231 of the two sub-mold cores 123 are separated from each other. Then, the exposed part 202 can be moved from between the mating surfaces 1231 of the two sub-mold cores 123 to the receiving groove 1231a of one of the sub-mold cores 123. Then, the two sub-mold cores 123 can be brought closer to each other, so that the first mold core 12 is in a closed state. Finally, the first mold core 12 in the closed state can be installed into the mounting position 112. When installing the semi-finished part 2000, the mating surfaces 1231 of the two sub-mold cores 123 are in a state of separation from each other; during the process of moving the exposed part 202 of the semi-finished part 2000 to the receiving groove 1231a, the semi-finished part 2000 can be moved along the length direction approximately perpendicular to the exposed part 202, thereby reducing the force on the exposed part 202 along its own length direction, reducing the risk of bending deformation of the exposed part 202, and thus improving the yield of the product after molding.
[0049] In some embodiments, the first mold base 11 has a mounting groove 113 on the side facing the second mold base 21, and the mounting position 112 is the mounting groove 113. The two sub-mold cores 123 of the first mold core 12, when in a closed state, are jointly embedded in the mounting groove 113. When it is necessary to remove the first mold core 12, it can be pulled out of the mounting groove 113. In other embodiments, the sub-mold cores 123 can also be detachably connected to the first mold base 11 by screws or snap-fit structures.
[0050] Reference Figure 4 In some embodiments, both sub-mold cores 123 are provided with mold cavities 121. In other embodiments, one of the two sub-mold cores 123 is provided with a mold cavity 121.
[0051] In some embodiments, two sub-mold cores 123 are arranged sequentially along a first direction X; it can be understood that the mutually facing sidewalls of the two sub-mold cores 123 are mating surfaces 1231.
[0052] Reference Figure 5 and Figure 6In some embodiments, the first mold core 12 further includes a guide member 124, which includes two guide protrusions 1241. The two guide protrusions 1241 are respectively disposed on both sides of the receiving groove 1231a and connected to a corresponding sub-mold core 123. The other sub-mold core 123 is provided with receiving holes 1232 for receiving the guide protrusions 1241. The two guide protrusions 1241 have the function of guiding the exposed portion 202 into the receiving groove 1231a. It can be understood that the guide protrusions 1241 are disposed on the mating surface 1231. In some embodiments, the guide protrusions 1241 and the mating surface 1231 are integrally formed. In other embodiments, the guide protrusions 1241 can be connected to the mating surface 1231 of the sub-mold core 123 by screws or other structures.
[0053] A channel is formed between the two guide protrusions 1241 that communicates with the receiving groove 1231a. As the exposed part 202 of the semi-finished material 2000 moves toward the receiving groove 1231a, the two guide protrusions 1241 can constrain the movement path of the exposed part 202 so that the exposed part 202 can move precisely into the receiving groove 1231a.
[0054] Reference Figure 5 In some embodiments, the sidewalls of the two guide protrusions 1241 facing each other are provided with guide surfaces 1241a, and the distance between the two guide surfaces 1241a gradually increases in the direction away from the corresponding receiving groove 1231a along the first direction X. In some embodiments, the ends of the two guide surfaces 1241a near the receiving groove 1231a are respectively connected to the inner sidewall of the corresponding side of the receiving groove 1231a. The guide surfaces 1241a can increase the distance between the two guide protrusions 1241 at the portions away from the receiving groove 1231a, thereby facilitating the movement of the exposed portion 202 of the semi-finished material 2000 between the two guide protrusions 1241, so as to facilitate the movement of the exposed portion 202 into the receiving groove 1231a.
[0055] Reference Figure 3 and Figure 4 In some embodiments, the first mold core 12 further includes a pressure strip 125, a magnetic element 126, and an adsorption element (not shown). One of the magnetic element 126 and the adsorption element is disposed on the pressure strip 125, and the other of the magnetic element 126 and the adsorption element is disposed on the sub-mold core 123. The magnetic element 126 and the adsorption element are magnetically attracted to each other. The pressure strip 125 is configured to clamp the portion of the semi-finished material 2000 located outside the mold cavity 121, respectively, with the sub-mold core 123. It can be understood that the pressure strip 125 is used to press the flexible tube 203 of the semi-finished material 2000 onto the sub-mold core 123 to achieve the effect of fixing the flexible tube 203.
[0056] In some embodiments, the magnetic element 126 is a magnet, and the pressure strip 125 has a mounting hole (not shown). The magnetic element 126 is embedded in the mounting hole and fixedly connected to the pressure strip 125 by screws. The adsorption element is made of a ferromagnetic material; exemplarily, the mold core 123 is made of a ferromagnetic material, and the adsorption element is part of the mold core 123. In other embodiments, the adsorption element is a patch, which is bonded to or connected to the mold core 123 by screws or other structures.
[0057] In some embodiments, positioning posts 1251 are provided at both ends of the pressure strip 125, and positioning holes 1233 are provided in the sub-mold core 123. The positioning posts 1251 can be inserted into the positioning holes 1233, which can improve the installation accuracy of the pressure strip 125.
[0058] In some embodiments, the sub-mold core 123 is provided with a placement groove 1234; the hose 203 of the semi-finished material 2000 is placed in the placement groove 1234, and the placement groove 1234 has a positioning and limiting effect on the hose 203, which can improve the stability of the hose 203 relative to the sub-mold core 123.
[0059] Reference Figure 4 In some embodiments, one of the sub-mold cores 123 is provided with a guide portion 1235 extending along a first direction X, and the other sub-mold core 123 is provided with an insertion portion 1236. The guide portion 1235 is inserted into the insertion portion 1236 and slides in cooperation with the insertion portion 1236 along the first direction X. Exemplarily, the guide portion 1235 is protruding, and the insertion portion 1236 is grooved. The guide portion 1235 being inserted into the insertion portion 1236 and sliding in cooperation with the insertion portion 1236 can improve the stability of the mutual sliding between the two sub-mold cores 123, and at the same time improve the accuracy of the mutual contact of the mating surfaces 1231 of the two sub-mold cores 123.
[0060] In some embodiments, the guide portion 1235 is integrally formed on the mating surface 1231 of the corresponding sub-mold core 123. In other embodiments, the guide portion 1235 may also be provided at other parts of the corresponding sub-mold core 123, as long as the guide portion 1235 can be inserted into the insertion portion 1236 and slide in cooperation with the insertion portion 1236.
[0061] Reference Figure 7 In some embodiments, the first mold core 12 further includes a connector 127, which is configured to connect two sub-mold cores 123 when the first mold core 12 is in a closed state, so as to constrain the relative position of the two sub-mold cores 123 in the first direction X, thereby improving the stability of the mating surfaces 1231 of the two sub-mold cores 123 in maintaining mutual mating, and reducing the risk of the semi-finished material 2000 falling off when the first mold core 12 moves toward the mounting position 112.
[0062] In some embodiments, the connector 127 includes a limiting rod 1271, a limiting protrusion 1272, and an elastic element 1273. The limiting rod 1271 and the limiting protrusion 1272 are respectively disposed on one of the sub-mold cores 123. In some embodiments, the mating surface 1231 of one sub-mold core 123 is provided with a first limiting hole 1237 along the first direction X, and the mating surface 1231 of the other sub-mold core 123 is provided with a second limiting hole 1238 along the first direction X. The first limiting hole 1237 and the second limiting hole 1238 are aligned in the first direction X. One end of the limiting rod 1271 is inserted into the first limiting hole 1237 and fixedly connected to the corresponding sub-mold core 123, and the other end of the limiting rod 1271 is inserted into the second limiting hole 1238. The limiting rod 1271 and the second limiting hole 1238 slide in cooperation along the first direction X. In some embodiments, the limiting rod 1271 is fixedly connected to the corresponding sub-mold core 123 by screws.
[0063] The limiting rod 1271 has a limiting groove 1271a on one side wall along the second direction Z, which intersects the first direction X. In some embodiments, the second direction Z is perpendicular to the first direction X.
[0064] The limiting protrusion 1272 is slidably disposed on the corresponding sub-mold core 123 along the second direction Z, and the elastic element 1273 connects the limiting protrusion 1272 and the corresponding sub-mold core 123. In some embodiments, the sub-mold core 123 with the second limiting hole 1238 is provided with a fixing groove 1238a along the second direction Z, and the fixing groove 1238a communicates with the second limiting hole 1238; a fixing block 1238b is embedded in the fixing groove 1238a, and the fixing block 1238b is fixedly connected to the corresponding sub-mold core 123 by screws; the fixing block 1238b is provided with a sliding hole 1238c through the second direction Z, and the fixing block 1238b moves away from the second limiting hole along the second direction Z. One end of the hole 1238 is provided with an abutment hole 1238d, and the limiting protrusion 1272 is slidably disposed in the sliding hole 1238c. The end of the limiting protrusion 1272 away from the second limiting hole 1238 is provided with an abutment block 1272a, which is located in the abutment hole 1238d. The elastic element 1273 is a spring, which is located in the abutment hole 1238d, and the two ends of the elastic element 1273 abut against the bottom of the abutment block 1272a and the groove of the fixing groove 1238a, respectively.
[0065] The limiting protrusion 1272 has a first driving surface 1272b and a second driving surface 1272c on both sides along the first direction X. Both the first driving surface 1272b and the second driving surface 1272c are inclined relative to the first direction X.
[0066] For ease of description, the direction in which the limiting rod 1271 moves toward the interior of the second limiting hole 1238 is defined as the positive direction of the first direction X, and the direction in which the limiting protrusion 1272 slides toward the second limiting hole 1238 is defined as the positive direction of the second direction Z. The angle between the first driving surface 1272b and the positive direction of the first direction X is an acute angle, and the angle between the second driving surface 1272c and the positive direction of the first direction X is an obtuse angle.
[0067] The first driving surface 1272b is configured to abut against the limiting rod 1271 when the limiting rod 1271 moves in the positive direction of the first direction X, so that the limiting protrusion 1272 is subjected to the opposite force of the limiting rod 1271 in the second direction Z, thereby causing the limiting protrusion 1272 to move in the opposite direction of the second direction Z, and the elastic member 1273 to undergo compression deformation, so that the elastic member 1273 has an elastic force on the limiting protrusion 1272 in the positive direction of the second direction Z; when the limiting protrusion 1272 and the limiting slot 1271a are aligned in the second direction Z, the elastic force of the elastic member 1273 causes the limiting protrusion 1272 to move in the positive direction of the second direction Z, so that the limiting protrusion 1272 is inserted into the limiting slot 1271a. When the two sub-mold cores 123 move away from each other, the limiting rod 1271 moves relative to the limiting protrusion 1272 in the opposite direction of the first direction X. The second driving surface 1272c abuts against the inner wall of the limiting groove 1271a. The inner wall of the limiting groove 1271a exerts a force on the limiting protrusion 1272 in the opposite direction of the second direction Z, causing the limiting protrusion 1272 to move away from the limiting rod 1271 in the opposite direction of the second direction Z, so that the limiting protrusion 1272 disengages from the limiting groove 1271a, allowing the limiting rod 1271 to continue moving in the opposite direction of the second direction Z.
[0068] In some other embodiments, the elastic element 1273 may be omitted, and the limiting protrusion 1272 may be inserted into or disengaged from the limiting slot 1271a by utilizing the toughness or elasticity of the limiting protrusion 1272 or the limiting rod 1271.
[0069] In some embodiments, the connector 127 may be a screw, and the two sub-mold cores 123 are connected to each other by the screw. In other embodiments, the connector 127 may also be a snap-fit structure or other structure that allows the two sub-mold cores 123 to be detachably connected to each other.

The disassembly fixture 3000 includes a fixture base plate 301, a first disassembly member 302, a second disassembly member 303, and a disassembly drive member 304. The fixture base plate 301 is provided with a support surface 3011, and the fixture base plate 301 is provided with a first mating hole 3012 and a second mating hole 3013 that pass through the support surface 3011. The first mating hole 3012 and the second mating hole 3013 are spaced apart along a first direction X. In some embodiments, the first direction X is parallel to the support surface 3011.
[0071] The first disassembly clamp 302 has a first connecting portion 3021, which is inserted into the first mating hole 3012, and the first connecting portion 3021 protrudes from the supporting surface 3011. The first disassembly clamp 302 is fixedly connected to the fixture base plate 301. The second disassembly clamp 303 has a second connecting portion 3031, which is inserted into the second mating hole 3013, and the second connecting portion 3031 protrudes from the supporting surface 3011. In the first direction X, there is a gap between the second disassembly clamp 303 and the second mating hole 3013, so that the second disassembly clamp 303 can slide relative to the fixture base plate 301 along the first direction X. In some embodiments, the first mating hole 3012 can be omitted, and the first disassembly clamp 302 can be provided on the side wall of the fixture base plate 301, as long as the first connecting portion 3021 protrudes from the supporting surface 3011. In other embodiments, the second disassembly clamp 303 may also be slidably connected to the fixture base plate 301 via a structure such as a slide rail.
[0072] The clamping drive 304 connects the first clamping member 302 and the second clamping member 303. The clamping drive 304 is configured to drive the first clamping member 302 and the second clamping member 303 to move away from and towards each other along a first direction X. Exemplarily, the second clamping member 303 is provided with a connecting rod 3032, and the clamping drive 304 is a cylinder. The cylinder body of the clamping drive 304 is connected to the fixture base plate 301, and the piston rod of the clamping drive 304 is connected to the connecting rod 3032. When the piston rod of the clamping drive 304 extends or retracts, the connecting rod 3032 can drive the second clamping member 303 to reciprocate along the first direction X. In other embodiments, the clamping drive 304 can be a linear motor or other structural components capable of driving the movement of the second clamping member 303.
[0073] The sub-mold core 123 is provided with a mating portion 1239. The first connecting portion 3021 is configured to be inserted into or fitted onto the mating portion 1239 of one of the sub-mold cores 123 of the first mold core 12 along a third direction W, where the third direction W intersects with the first direction X. The second connecting portion 3031 is configured to be inserted into or fitted onto the mating portion 1239 of another sub-mold core 123 of the first mold core 12 along a third direction W. In some embodiments, the third direction W is perpendicular to the first direction X and perpendicular to the support surface 3011.
[0074] For example, the mating part 1239 is hole-shaped, and the mating part 1239 is located on the mold core 123 away from the mold cavity 121 (see Figure 4 On one side of the first connecting part 3021 and the second connecting part 3031 are both protruding blocks. When the first mold core 12 in the closed state is moved toward the support surface 3011 in the third direction W, the first connecting part 3021 can be inserted into the mating part 1239 of one of the sub-mold cores 123, and the second connecting part 3031 can be inserted into the mating part 1239 of the other sub-mold core 123, so that the first disassembly member 302 and the second disassembly member 303 are respectively connected to the corresponding sub-mold cores 123. When the disassembly drive 304 drives the second disassembly member 303 away from the first disassembly member 302, the second disassembly member 303 drives the corresponding sub-mold core 123 to move, so that the two sub-mold cores 123 separate from each other, so as to facilitate the installation of the semi-finished material 2000 or the disassembly of the molded product; after the semi-finished material 2000 is installed, the disassembly drive 304 drives the second disassembly member 303 to approach the first disassembly member 302, so that the mating surfaces 1231 of the two sub-mold cores 123 can be mated together, and then the two first sub-mold cores 123 can be moved away from the support surface 3011 in the third direction W, so that the first mold core 12 can be removed.
[0075] In some embodiments, neither the first disassembly member 302 nor the second disassembly member 303 protrudes from the support surface 3011, which is configured to support the sub-mold core 123. In other embodiments, the first disassembly member 302 and the second disassembly member 303 may protrude from the support surface 3011 and respectively support the corresponding sub-mold core 123.
[0076] In some embodiments, the fixture base plate 301 may be omitted, and the first disengaging clamp 302 and the second disengaging clamp 303 may be respectively disposed on the disengaging clamp drive 304; for example, the first disengaging clamp 302 is disposed on the cylinder of the disengaging clamp drive 304, and the second disengaging clamp 303 is disposed on the piston rod of the disengaging clamp drive 304. In some embodiments, the disengaging clamp drive 304 may also be a pneumatic gripper, with the first disengaging clamp 302 disposed on one of the grippers of the pneumatic gripper, and the second disengaging clamp 303 disposed on the other gripper of the pneumatic gripper.
[0077] Reference Figure 8 and Figure 10In some embodiments, the disassembly fixture 3000 further includes a first positioning block 305 and a second positioning block 306; the first positioning block 305 is disposed on the fixture base plate 301 and configured to stop the die core 123 in the fourth direction U, and the second positioning block 306 is disposed on the fixture base plate 301 and configured to stop the die core 123 in the fifth direction V. Both the fourth direction U and the fifth direction V are parallel to the support surface 3011, and the fourth direction U and the fifth direction V intersect. In some embodiments, the fourth direction U is parallel to the first direction X, and the fifth direction V is perpendicular to the fourth direction U.
[0078] In some embodiments, a first positioning block 305 is disposed on one side of the support surface 3011 along the fourth direction U, and a second positioning block 306 is disposed on one side of the support surface 3011 along the fifth direction V. The first positioning block 305 and the second positioning block 306 cooperate with each other to constrain the position of the sub-mold core 123 relative to the support surface 3011, so that the mating part 1239 is aligned with the corresponding first connecting part 3021 or second connecting part 3031 in the third direction W, thereby facilitating the quick connection of the sub-mold core 123 with the corresponding first disassembly clamp 302 or second disassembly clamp 303.
[0079] In some embodiments, the portion of the first connecting portion 3021 protruding from the support surface 3011 has a dimension L1 in the third direction W; the portion of the second connecting portion 3031 protruding from the support surface 3011 has a dimension L2 in the third direction W; the portion of the first positioning block 305 protruding from the support surface 3011 has a dimension L3 in the third direction W; and the portion of the second positioning block 306 protruding from the support surface 3011 has a dimension L4 in the third direction W. L1 is less than L3 and L4, and L2 is less than L3 and L4. For example, L1 equals L2, and L3 equals L4. Before the mating part 1239 mates with the corresponding first connecting part 3021 or the corresponding second connecting part 3031, the sub-mold core 123 can be made to abut against the first positioning block 305 and the second positioning block 306 to position the sub-mold core 123. Then, the sub-mold core 123 is moved toward the support surface 3011 along the third direction W, so that the mating part 1239 can quickly mate with the corresponding first connecting part 3021 or the corresponding second connecting part 3031.
