Description

Technical Field

[0001] The present invention relates to the technical field of connector mold design, and particularly relates to a mold slider structure, a mold clamping mechanism and a manufacturing method of a side-sealing hardware product. Background Art

[0002] In the process of manufacturing a connector product composed of a hardware part and a plastic part, generally, the hardware part is first manufactured, and then the hardware part is separately placed in the mold core and the plastic part is molded by injection, so as to obtain a connector product in which the hardware part and the plastic part are integrally molded. In the connector product manufactured by this process, the combination between the hardware part and the plastic part is good and the firmness is high.

[0003] In the prior art, the mold slider structure for molding the hardware part and the plastic part is as Figure 1 shown, which includes a slider insert 100 and a slider base 200 fixedly connected. Before the slider is closed, the hardware part is first placed in the hardware part installation groove of the mold core. During the process of closing the slider, the power mechanism drives the slider base 200 and the slider insert 100 as a whole to move towards the mold cavity of the mold core in a direction perpendicular to the side opening of the mold core, so that the hardware part is inserted into the slider hole 110 of the slider insert 100, and then the connector product is injection molded.

[0004] However, since the hardware part has a coating and the periphery of the hardware part needs to be sealed with glue, the maximum gap between the slider hole cooperating with the hardware part and the hardware part can only be set to 0.02 - 0.03 mm on one side. Due to the small clearance fit, during the process of closing the slider, the slider insert and the hardware part often rub against each other, resulting in copper leakage on the coating of the hardware part. Seriously, it will cause mold pressing, affecting production efficiency and product stability, and increasing the defective rate. Summary of the Invention

[0005] In view of this, the present invention provides a mold slider structure, a mold clamping mechanism and a manufacturing method of a side-sealing hardware product, so as to solve the problem that in the prior art, during the process of closing the slider, the slider insert and the hardware part will cause copper leakage on the hardware part due to friction, and even damage due to mold pressing.

[0015] Further, the movable insert includes an insert body connected to the forming block and two buckle bodies located on opposite sides of the insert body, the buckle bodies protrude outward from the side of the insert body to form a clamping groove with the insert body; in the direction of connection between the slider base and the slider insert group, the buckle member can be buckled with the buckle body; in a direction perpendicular to the connection between the slider base and the slider insert group, the buckle member is slidably connected to the clamping groove.

[0016] Further, a handle structure protruding above the slider insert group is further provided above the insert body.

[0017] Furthermore, glass ball screws are provided on two opposite side walls of the forming block that cooperate with the inner wall of the mold core.

[0018] The embodiment of the present invention further provides a mold clamping mechanism, comprising:

[0019] A mold core having a mold cavity formed thereon, wherein the mold cavity has a side opening and a top opening;

[0020] The slide structure adopts the mold slide structure as described above, and the mold slide structure includes a slide insert group and a slide seat that are detachably connected. The slide insert group can be embedded in the mold cavity from a direction perpendicular to the top opening and cooperate with the mold core to form a molding space for the product; the slide seat can be buckled with the slide insert group from a direction perpendicular to the side opening under the constraint of a guide structure;

[0021] A power mechanism, whose driving force acts on the slide seat, is used to drive the slide seat to move along the guide direction of the guide structure close to the slide insert group until it is engaged with the slide insert group or drives the slide seat to drive the slide insert group to disengage from the mold cavity to achieve demolding.

[0022] Furthermore, a guide groove is provided on the inner wall of the mold core corresponding to the glass ball screw.

[0023] The embodiment of the present invention further provides a method for manufacturing a side-sealed hardware product, using the above-mentioned mold clamping mechanism, comprising the following steps:

[0024] Insert the hardware into the slide holes of the slide insert assembly;

[0025] Put the slide insert assembly into the mold cavity of the mold core vertically from above the top opening of the mold cavity;

[0027] After the injection molding is completed, the power mechanism drives the slide seat and the slide insert assembly to move outward together;

[0028] The ejector mechanism ejects the product in the mold cavity.

[0029] 1. The mold slider structure provided by the present invention has a detachable connection structure between the slider insert group and the slider seat. Before mold closing, the slider insert group and the slider seat are separated. The hardware parts can be installed in the slider insert group outside the mold first, and then the slider insert group with the installed hardware parts is placed into the mold core. During mold closing, the slider seat is buckled with the clamping part on the slider insert group through the buckle parts thereon to realize the connection between the two. During the demolding process, the slider seat can drive the slider insert group to move outwards together to realize demolding. After demolding, the slider insert group can be taken out from the slider seat along the direction perpendicular to the mold closing direction, which is convenient for disassembly and assembly. During the mold closing process of this mold slider structure, there is no moving friction between the hardware parts and the slider insert group, preventing problems such as abrasion and copper leakage of the hardware parts, and even damage to the mold due to pressing, thereby improving the stability of the product and reducing the defective rate of the product. It should be noted here that since the slider seat can only be slidably connected to the guiding structure of the mold, the movement direction of the slider seat is restricted by the guiding structure and can only move along the mold closing or demolding direction. Therefore, when the slider seat and the slider insert group adopt an integrated structural design, it is not possible to simply place the hardware parts on the slider insert group fixedly connected to the slider seat first, and then place the overall slider structure containing the hardware parts on the mold. In addition, due to the limitation of the bent shape of the hardware parts, the hardware parts must be placed into the hardware part installation cavity on the mold core before mold closing.

[0030] 2. In the mold slider structure provided by the present invention, during the mold closing process, the hook parts of a pair of buckle parts on the slider seat rotate around the pin shaft and open outwards after contacting the clamping part of the slider insert group. At this time, the elastic part abutted against the force application part is compressed. When the slider seat moves to the position where it fits with the slider insert group, the acting force of the clamping part on the hook part disappears, and the elastic part drives the force application part to rotate around the pin shaft in the opposite direction, driving the hook part to buckle the clamping part, realizing the locking of the slider seat and the slider insert group in the demolding direction, so that the slider seat can drive the slider insert group to move outwards to realize demolding.

[0031] 3. In the mold slider structure provided by the present invention, a pair of buckle parts are respectively arranged in two installation grooves on the opposite sides of the slider body. The buckle parts can only make rotational movements around the axial direction of the pin shaft and cannot make movements along the axial direction of the pin shaft, which can improve the installation structural stability of the buckle parts, and further ensure the stability during the mold closing and demolding processes.

[0032] 4. In the mold slider structure provided by the present invention, a structural setting is provided where the gap between the part of the force application part abutting against the elastic part and the bottom of the installation groove is at least 0.2 cm larger than the protruding height of the chuck, which can enable the hook part to successfully buckle the clamping part.

[0033] 5. The mold slider structure provided by the present invention adopts the method of separately manufacturing the forming block and the movable insert block and then fixedly connecting them to form a slider insert group, which reduces the mold opening manufacturing difficulty of the slider insert group.

[0034] 6. In the mold closing direction where the slider seat and the slider insert group of the mold slider structure provided by the present invention are connected, the snap member and the buckle body are buckled to realize the connection between the slider insert group and the slider seat, and then they move outward together to realize demolding; in the direction perpendicular to the connection between the slider seat and the slider insert group, the snap member is slidably connected to the card slot, which is convenient for taking out the slider insert group from the slider seat, and then installing the next hardware part on the slider insert group. The specific structure is simple and the operation is convenient.

[0035] 7. The mold slider structure provided by the present invention is provided with a handle structure protruding upward above the insert block body, which is convenient for manually or by a manipulator to vertically lift the slider insert group from the slider seat.

[0036] 8. The mold slider structure provided by the present invention is provided with glass bead screws on the opposite two side walls where the forming block cooperates with the inner wall of the mold core, which is convenient for positioning and installing the slider insert group on the mold core.

[0037] 9. The mold closing mechanism provided by the present invention adopts the above-mentioned mold slider structure. Before mold closing, the slider insert group and the slider seat are separated. The hardware part can be installed in the slider insert group outside the mold first, and then the slider insert group with the installed hardware part is vertically inserted into the mold cavity from the top opening of the mold cavity; during mold closing, the power mechanism drives the slider seat to move in the mold closing direction, so that the slider seat is buckled with the clamping part on the slider insert group through the snap member thereon to realize the connection between the two; during demolding, the power mechanism drives the slider seat to move in the demolding direction and drives the slider insert group to move outward together to realize demolding; during the mold closing process of this mold closing mechanism, there is no movement friction between the hardware part and the slider insert group, which can prevent problems such as abrasion and copper leakage of the hardware part, and even damage to the mold due to pressing, thereby improving the stability of the product and reducing the defective rate of the product.

[0038] 10. The mold closing mechanism provided by the present invention is provided with a guide groove on the inner wall of the mold core corresponding to the glass bead screws, which can cooperate to realize the precise positioning and installation of the slider insert group on the mold core and avoid problems with the product quality due to unstable installation position of the slider insert group.

[0039] 11. The manufacturing method of the side-sealed rubber-metal product provided by the present invention adopts the above-mentioned mold clamping mechanism. Before mold clamping, the metal part is first installed in the slide insert group outside the mold, and then the slide insert group with the installed metal part is vertically placed into the mold cavity from the top opening of the mold cavity; during the mold clamping process, the power mechanism drives the slide seat to move in the mold clamping direction, so that the buckle on the slide seat is engaged with the clamping part on the slide insert group to realize the connection between the two; during the demolding process after injection molding, the power mechanism drives the slide seat to move in the demolding direction and drives the slide insert group to move outwards together to realize demolding; this manufacturing method of the side-sealed rubber-metal product can prevent problems such as abrasion and copper leakage of the metal part, and even damage to the mold, thereby improving the stability of the product and reducing the defective rate of the product.

[0054] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] Such as Figure 2A connector product 7 as shown includes a hardware part 71 and a plastic part 72. The plastic part 72 is sealed to the hardware part 71 to form the connector product 7. The mold slider structure, the mold clamping mechanism and the manufacturing method of the side-sealed hardware product provided by the embodiments of the present invention are mainly used to manufacture such side-sealed hardware products.

[0056] As Figure 3 shown, the embodiments of the present invention provide a mold slider structure, including a slider insert group 1 and a slider seat 2 which are movably connected; wherein, the slider insert group 1 includes a molding part 11 and a clamping part 12 which are oppositely arranged. The molding part 11 can be embedded into the mold cavity 4 of the mold core 3 and cooperate with the mold core 3 to form a molding space for the product; the slider seat 2 is located at one end of the slider insert group 1 facing away from the mold core 3. The slider seat 2 includes a slider body 21 and a buckle member 22 movably installed on the slider body 21. During the mold clamping process of the slider, the buckle member 22 is buckled with the clamping part 12 along the mold clamping direction to connect the slider seat 2 and the slider insert group 1. Wherein, the mold clamping direction is the moving direction of the slider seat 2, that is, the connecting direction of the slider insert group 1 and the slider seat 2. It should be noted here that since the slider seat 2 can only be slidably connected to the guiding structure of the mold, the moving direction of the slider seat 2 is restricted by the guiding structure and can only move along the mold clamping or demolding direction. Therefore, when the slider seat 2 and the slider insert group 1 adopt an integrated structural design, it is not possible to simply place the hardware part 71 on the slider insert group 1 fixedly connected to the slider seat 2 first, and then place the whole slider structure containing the hardware part 71 on the mold. In addition, due to the limitation of the bent shape of the hardware part 71, the hardware part 71 must be placed in the hardware part installation cavity on the mold core 3 before mold clamping.

[0057] For this mold slider structure with a detachable connection between the slider insert group 1 and the slider seat 2, before mold clamping, the slider insert group 1 and the slider seat 2 are separated. The hardware part 71 can be installed in the slider insert group 1 outside the mold first, and then the slider insert group 1 with the installed hardware part 71 is placed into the mold core 3; during the mold clamping process, the slider seat 2 is buckled with the clamping part 12 on the slider insert group 1 through the buckle member 22 on it to realize the connection between the two; during the demolding process, the slider seat 2 can drive the slider insert group 1 to move outwards together to realize demolding; after demolding, the slider insert group 1 can be taken out from the slider seat 2 along the direction perpendicular to the mold clamping direction, and the disassembly and assembly are convenient. During the mold clamping process of this mold slider structure, there is no moving friction between the hardware part 71 and the slider insert group 1, preventing problems such as abrasion and copper leakage of the hardware part 71, and even mold pressing damage, thereby improving the stability of the product and reducing the defective rate of the product.

[0058] Combined with Figure 4 and Figure 5As shown, in this embodiment, mounting grooves 211 are respectively provided on opposite sides of the slider body 21, and the openings of the mounting grooves 211 are located on the side edges of the slider body 21. A pin shaft 23 is also provided on the slider body 21 and is connected between opposite side walls of the mounting groove 211, and the axial direction of the pin shaft 23 is perpendicular to the mold closing direction. There are two snap members 22 which are respectively located in the mounting grooves 211. The middle part of the snap member 22 is sleeved on the pin shaft 23 and can rotate around the pin shaft 23. The structure in which a pair of snap members 22 are respectively arranged in the two mounting grooves 211 on opposite sides of the slider body 21 enables the snap members 22 to only make rotational movements around the axial direction of the pin shaft 23, rather than making movements along the axial direction of the pin shaft 23, which can improve the stability of the mounting structure of the snap members 22, and further ensure the stability during the mold closing and demolding processes.

[0059] Combined with Figure 4 and Figure 5 As shown, specifically, the snap member 22 includes a hook portion 221 and a force application portion 222 which are respectively located on opposite sides of the pin shaft 23. The hook portion 221 is used for engaging with the engaging portion 12 of the slider insert group 1; an elastic member 24 is provided on the slider body 21 and abuts against one end of the force application portion 222 to drive the force application portion 222 to rotate around the pin shaft 23, thereby locking the hook portion 221 with the engaging portion 12. During the mold closing process, the hook portions 221 of a pair of snap members 22 on the slider seat 2 rotate around the pin shaft 23 and open outwards after contacting the engaging portion 12 of the slider insert group 1. At this time, the elastic member 24 which abuts against the force application portion 222 is compressed; when the slider seat 2 moves to a position where it fits with the slider insert group 1, the acting force of the hook portion 221 on the engaging portion 12 disappears, and the elastic member 24 drives the force application portion 222 to rotate around the pin shaft 23 in the opposite direction to drive the hook portion 221 to latch the engaging portion 12, realizing the locking of the slider seat 2 and the slider insert group 1 in the demolding direction, so that the slider seat 2 can drive the slider insert group 1 to move outwards to achieve demolding.

[0060] Combined with Figure 4 and Figure 5 As shown, specifically, the slider body 21 is provided with a receiving groove 212 for accommodating the elastic member 24. The opening of the receiving groove 212 is located at the bottom of the mounting groove 211, and the elastic member 24 is a compression spring which extends out from the opening of the receiving groove 212 and abuts against the force application portion 222.

[0061] Combined with Figure 4 and Figure 5As shown, in this embodiment, the end of the hook portion 221 extending out of the installation groove 211 is provided with a protruding catch head 223, and the catch head 223 is provided with an inclined guide surface 2231 extending obliquely inward from the outside; when the clamping portion 12 of the slider insert group 1 starts to contact the catch head 223, the clamping portion 12 abuts against the inclined guide surface 2231, and the slider seat 2 continues to approach the slider insert group 1, causing a pair of snap members 22 to open outward until the slider seat 2 and the slider insert group 1 are completely fitted, and the snap members 22 lock the slider insert group 1 under the action of the elastic member 24 to complete the mold closing. Specifically, there is a gap between the portion of the force application portion 222 abutting against the elastic member 24 and the bottom of the installation groove 211; when the snap member 22 is completely latched with the slider insert group 1, the distance of this gap is 0.2 cm larger than the protruding height of the catch head 223. Setting a gap with such a size distance between the force application portion 222 and the bottom of the installation groove 211 facilitates the snap member 22 to successfully latch the slider insert group 1.

[0062] Combined with Figure 6 As shown, in this embodiment, the slider insert group 1 includes a forming block 13 and a movable insert 14 connected to the forming block 13. Among them, the forming portion 11 is located on the forming block 13, and the clamping portion 12 is located on the movable insert 14; the forming block 13 can be embedded in the mold cavity 4 of the mold core 3 and cooperate with the mold core 3 to form a forming space for the product, and the movable insert 14 is used to engage with the snap members 22 of the slider seat 2. By adopting the method of separately manufacturing the forming block 13 and the movable insert 14 and then fixedly connecting them to form the slider insert group 1, the mold opening manufacturing difficulty of the slider insert group 1 can be reduced. Since the structure of the plastic part 72 of some connector products 7 is complex, the outer shape of the forming block 13 for injection molding the plastic part 72 is also relatively complex. In order to further reduce the manufacturing difficulty of the forming block 13, the forming block 13 is also separately manufactured from multiple blocks and then fixedly connected to form an integral forming block 13 with the forming portion 11.

[0063] Combined with Figure 6 As shown, specifically, the slider hole 131 for the insertion and cooperation of the hardware part 71 is located on one of the forming blocks 13. Glass bead screws 6 are provided on the opposite two side walls of the forming block 13 that cooperate with the inner wall of the mold core 3 to facilitate the positioning and installation of the slider insert group 1 on the mold core 3.

[0064] Combined with Figure 6As shown, in the present embodiment, the movable insert 14 includes an insert body 141 connected to the forming block 13 and two buckle bodies 142 located on opposite sides of the insert body 141, the buckle bodies 142 protrude outward from the side of the insert body 141 to form a slot 5 with the insert body 141; in the direction in which the slide seat 2 and the slide insert assembly 1 are connected, the buckle 22 can be buckled with the buckle body 142; in the direction perpendicular to the connection between the slide seat 2 and the slide insert assembly 1, the buckle 22 is slidably connected to the slot 5. In the mold closing direction where the slider seat 2 and the slider insert group 1 are connected, the fastener 22 is engaged with the buckle body 142 to realize the connection between the slider insert group 1 and the slider seat 2, and then they move outward together to realize demoulding; in the direction perpendicular to the connection between the slider seat 2 and the slider insert group 1, the fastener 22 is slidably connected with the slot 5, which makes it easy to remove the slider insert group 1 from the slider seat 2, and then install the next hardware 71 on the slider insert group 1, which has the advantages of simple structure and easy operation.

[0065] Combination Figure 6 As shown, further, a handle structure 143 protruding from the top of the slide insert assembly 1 is formed on the top of the insert body 141. The arrangement of the handle structure 143 facilitates manual or mechanical hand to vertically take out the slide insert assembly 1 from the slide seat 2.

[0066] like Figure 3 As shown, the embodiment of the present invention also provides a mold closing mechanism, including a mold core 3, a mold slide structure as described in the above embodiment, a guide structure (not shown) and a power mechanism (not shown). Among them, a mold core 3 is provided with a mold cavity 4, and the mold cavity 4 has a top opening 42 and a side opening 41 corresponding to the mold closing direction. The mold slide structure includes a slide insert group 1 and a slide seat 2 that are detachably connected. The slide insert group 1 can be embedded in the mold cavity 4 from a direction perpendicular to the top opening 42 and cooperate with the mold core 3 to form a molding space for the product; the slide seat 2 can be engaged with the slide insert group 1 from a direction perpendicular to the side opening 41 under the constraint of the guide structure. The inclined guide column of the power mechanism is connected to the inclined guide column mounting hole of the slide seat 2. The power mechanism drives the slide seat 2 to move close to the slide insert group 1 along the guide direction of the guide structure through the inclined guide column until it is engaged with the slide insert group 1 to achieve mold closing or drives the slide seat 2 to drive the slide insert group 1 to disengage from the mold cavity 4 to achieve demolding.

[0067] This mold clamping mechanism adopts the mold slide structure described in the above embodiment. Before mold clamping, the slide insert group 1 and the slide base 2 are separated. The hardware part 71 can be installed in the slide insert group 1 outside the mold first, and then the slide insert group 1 with the installed hardware part 71 is vertically placed into the mold cavity 4 from the top opening 42 of the mold cavity 4; during the mold clamping process, the power mechanism drives the slide base 2 to move in the mold clamping direction, so that the slide base 2 is buckled with the clamping part 12 on the slide insert group 1 through the buckle 22 on it to realize the connection between the two; during the demolding process, the power mechanism drives the slide base 2 to move in the demolding direction and drives the slide insert group 1 to move outwards together to realize demolding; during the mold clamping process of this mold clamping mechanism, there is no moving friction between the hardware part 71 and the slide insert group 1, which can prevent problems such as abrasion and copper leakage of the hardware part 71 and even damage to the mold due to pressing, thereby improving the stability of the product and reducing the defective rate of the product.

[0068] Combined with Figure 3 、 Figure 6 and Figure 7 As shown, specifically, guide grooves 31 are provided on both inner walls of the mold core 3 corresponding to the glass bead screws 6. The setting of the guide grooves 31 can cooperate to realize the accurate positioning and installation of the slide insert group 1 on the mold core 3, and avoid problems with the quality of the product due to unstable installation position of the slide insert group 1.

[0069] As Figure 8 shown, the embodiment of the present invention also provides a manufacturing method for a side-sealed rubberized hardware product, which adopts the above mold clamping mechanism, and specifically includes the following steps:

[0070] The first step is to insert the hardware part 71 into the slide hole 131 of the slide insert group 1;

[0071] The second step is to vertically place the slide insert group 1 into the mold cavity 4 of the mold core 3 from above the top opening 42 of the mold cavity 4;

[0072] The third step is that the power mechanism drives the slide base 2 to move in a direction perpendicular to the side opening 41 of the mold cavity 4, so that the buckle 22 on the slide base 2 and the clamping part 12 of the slide insert group 1 are buckled together

[0073] The fourth step is that after injection molding, the power mechanism drives the slide base 2 and the slide insert group 1 to move outwards together;

[0074] The fifth step is that the ejection mechanism ejects the product in the mold cavity 4. In this embodiment, the product is specifically a connector.

[0075] The manufacturing method of this side-sealed hardware product adopts the above-mentioned mold clamping mechanism. Before mold clamping, the hardware part 71 is first installed in the slide insert group 1 outside the mold, and then the slide insert group 1 with the installed hardware part 71 is vertically inserted into the mold cavity 4 from the top opening 42 of the mold cavity 4. During the mold clamping process, the power mechanism drives the slide seat 2 to move in the mold clamping direction, so that the buckle 22 on the slide seat 2 is engaged with the engaging part 12 on the slide insert group 1 to realize the connection between the two. During the demolding process after injection molding, the power mechanism drives the slide seat 2 to move in the demolding direction and drives the slide insert group 1 to move outwards together to realize demolding. This manufacturing method of the side-sealed hardware product can prevent problems such as abrasion and copper leakage of the hardware part 71, and even mold pressing damage, thereby improving the stability of the product and reducing the defective rate of the product.

[0076] In summary, for the mold slide structure, mold clamping mechanism and manufacturing method of the side-sealed hardware product provided by the embodiments of the present invention, before mold clamping, the slide insert group 1 and the slide seat 2 are separated. The hardware part 71 can be first installed in the slide insert group 1 outside the mold, and then the slide insert group 1 with the installed hardware part 71 is placed into the mold core 3. During the mold clamping process, the slide seat 2 is engaged with the engaging part 12 on the slide insert group 1 through the buckle 22 on it to realize the connection between the two. During the demolding process, the slide seat 2 can drive the slide insert group 1 to move outwards together to realize demolding, so as to prevent problems such as abrasion and copper leakage of the hardware part 71, and even mold pressing damage, thereby improving the stability of the product and reducing the defective rate of the product.
