Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a mold for positioning pre-embedded inserts. Background Technology

[0002] In the mold industry, such as in composite material compression molding, mold structures using upper and lower molds enable rapid product prototyping. The positioning methods for inserts in these products typically include mold structure positioning, detachable insert positioning, and slider positioning. When designing molds with embedded inserts, different positioning methods are used depending on the insert's structure and requirements. Insert positioning can also involve two or more methods, such as: internal mold structure positioning + external detachable insert positioning, internal mold structure positioning + external slider positioning, external detachable insert positioning + external slider positioning, or all three methods used simultaneously.

[0003] For double-end positioning of inserts in products, using only mold structure positioning or external detachable insert positioning is insufficient; therefore, a combination of both methods is necessary. The specific operation involves first removing the detachable insert along with the product, then separating it in subsequent processes to achieve closed-loop management during product molding. When using the above positioning method for pre-embedded insert compression molding, a positioning insert is typically added inside the mold. After product molding, the mold and product open simultaneously, and the pre-embedded insert and positioning insert are removed along with the product. The positioning insert then needs to be manually removed. While this solution satisfies double-end positioning of the insert, it increases additional processes, time, and labor costs, leading to low production efficiency and ineffective cost control. Manual removal of the positioning insert reduces the continuity of compression molding production, and the positioning insert is prone to wear or damage during repeated disassembly and assembly, affecting mold lifespan and increasing maintenance costs. Furthermore, the detachable insert is at risk of damage during secondary operations, increasing repair costs. The product also faces the risk of damage during secondary operations, increasing the product defect rate.

[0004] If the head end of the insert in the product is positioned by a mold structure while the tail end is positioned by a slider, then although the slider can move away from the product surface when the mold opens, it cannot position the insert at the tail end before the mold closes. As a result, the insert cannot meet the requirement of double-end positioning before the mold closes.

[0005] If the insert in a product uses a detachable insert for positioning at the head end and a slider for positioning at the tail end, then the process of removing the detachable insert along with the product simultaneously and separating the detachable insert from the product in subsequent processes cannot be avoided. Furthermore, the slider cannot meet the requirement that the insert achieve double-end positioning before mold closing.

[0006] If the insert in the product uses three positioning methods at the same time, with the head end of the insert being positioned by a detachable insert, the middle of the insert being positioned by a mold structure, and the tail end being positioned by a slider, the above situation will also occur, and this solution will not meet the usage requirements.

[0007] Therefore, there is an urgent need for a mold structure that can meet the requirement of double-end positioning of inserts before product molding, and that the external positioning structure can move away from the product surface when the mold opens, and achieve precise positioning of embedded parts during the molding process and automatic, manual removal when the mold opens. Summary of the Invention

Detailed Implementation

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] First, the technical terminology used in this application is provided: Embedded inserts are specific components, parts, or accessories that are pre-installed in a mold or workpiece during the molding process. These inserts are typically embedded into the workpiece's structure to achieve specific functions or characteristics. Embedded inserts can include bolts, nuts, metal parts, plastic parts, electronic components, etc. Embedded inserts are used to provide connections, fixation, support, guidance, or other functions after molding.

[0025] Positioning inserts are embedded components used to ensure the accurate positioning of internal or external elements of a molded part. Positioning inserts are typically made of different materials, such as metal, plastic, or others. They are installed in the molding die to ensure the positioning and alignment of parts (such as pre-embedded inserts) during the molding process.

[0026] The relevant technologies for this application are provided below: In the composite materials industry, the use of compression molding has greatly reduced the product molding cycle. However, the structure of compression molds remains relatively unchanged, still using the conventional upper and lower mold structure. When the product requires embedded inserts, the conventional mold structure adds a positioning insert to position the embedded insert. After the product is formed, the mold is opened simultaneously with the product. After the product is removed, the positioning insert is manually removed. However, this method of removing the positioning insert is labor-intensive and time-consuming, and the lifespan of the positioning insert is shortened due to frequent manual disassembly.

[0027] To resolve the above issues, please refer to Figures 1 to 11 This application provides a mold for positioning a pre-embedded insert, including: a first mold 11, a second mold 12, a movable block 14, and a positioning insert 15. A detailed description follows.

[0028] The first mold 11 has a first mold core 111 and an outwardly inclined guide post 113 fixed on the side facing the second mold 12.

[0029] The second mold 12 has a second mold core 122 fixed on the side facing the first mold 11 and is provided with a slide groove 121. The second mold core 122 is arranged correspondingly to the first mold core 111.

[0030] The movable block 14 is slidably located within the slide groove 121 and can move along the limiting direction within the slide groove 121. The movable block 14 is provided with a guide hole 141 for the guide post 113 to be inserted.

[0031] The positioning insert 15 is used to fix the pre-embedded insert 20. The insert 20 is also called the pre-embedded insert.

[0032] Wherein, after the first mold 11 and the second mold 12 are closed, the first mold core 111 and the second mold core 122 cooperate to form a cavity (not shown in the figure) and a positioning groove (not shown in the figure) located on one side of the cavity. The cavity is used for (product or workpiece) molding, the positioning groove is used to accommodate the positioning insert 15, the insert 20 is at least partially embedded in the cavity, the guide post 113 is inserted into the guide hole 141, and the movable block 14 is engaged with the positioning insert 15.

[0033] When the first mold 11 and the second mold 12 are opened, the movable block 14 is used to drive the positioning insert 15 and the insert 20 to separate.

[0034] Please refer to Figure 6 During the process of closing the first mold 11 and the second mold 12, the guide post 113 is gradually inserted into the guide hole 141. Since the guide post 113 is inclined outward, during the process of the guide post 113 being gradually inserted into the guide hole 141, the movable block 14 will have relative movement due to the interference of the guide post 113. That is, the movable block 14 will move inward along the slide groove 121 until the first mold 11 and the second mold 12 are completely closed. Then the movable block 14 moves inward to the predetermined position to engage with the positioning insert 15.

[0035] Please refer to Figure 7After the mold is closed, the mold is formed. Since the positioning insert 15 is connected to the insert 20, the insert 20 is fixed by the positioning insert 15 so that the insert 20 can be positioned in the expected position during the workpiece (or product) forming process.

[0036] Please refer to Figure 8 After the mold is formed, when the first mold 11 and the second mold 12 open, as the guide post 113 gradually pulls out of the guide hole 141, the movable block 14 will move relative to the guide post 113 due to the interference of the guide post 113. That is, the movable block 14 will move outward along the slide groove 121. Since the movable block 14 is engaged with the positioning insert 15, the movable block 14 can drive the positioning insert 15 to move outward to separate the positioning insert 15 from the insert 20. It can be seen that the positioning insert 15 and the insert 20 can be automatically separated during the mold opening process without manual removal. The steps are simple, and this method of separating the positioning insert 15 and the insert 20 can avoid damage to the insert 20 or the positioning insert 15 caused by various unstable factors during manual separation, thus extending the service life of the positioning insert 15.

[0037] In an optional embodiment, the movable block 14 is provided with a hook 142 on one side, and the positioning insert 15 is provided with a groove 151 on the side facing the hook 142; The second mold is also provided with a separation groove 25, and the hook is also provided with an elastic limiting member 21, which is used to cooperate with the separation groove 25. Wherein, after the first mold 11 and the second mold 12 are closed, the hook 142 is engaged in the slot 151 and hooked to the positioning insert 15. The elastic limiting member 21 on the hook can be slidably inserted into the separation groove 25. The hook slides along the separation groove 25 under the drive of the movable block so that the hook is disengaged from the positioning insert.

[0038] Specifically, the elastic limiting member 21 can be a ball screw, and the ball of the ball screw can be used to cooperate with the separation groove 25 so that when the movable block moves, it drives the hook connected to it to slide along the separation groove, so that the hook disengages from the positioning insert. When the elastic limiting member 21 slides to the end of the separation groove, it limits the hook 142 on the movable block 14, waiting to enter the next cycle.

[0039] During the mold closing process of the first mold 11 and the second mold 12, the movable block 14 gradually approaches the positioning insert 15, causing the hook 142 on the movable block 14 to gradually approach the positioning insert 15 until the hook 142 engages with the slot 151 on the positioning insert 15. By utilizing the cooperation of the hook and the slot, the movable block 14 can drive the positioning insert 15 to move when the mold is opened.

[0040] Please combine Figure 12 and Figure 13 By setting an elastic limiting element on the hook and a separation groove on the second mold that cooperates with the elastic limiting element, the hook can engage with the groove of the positioning insert when the first and second molds are closed, thus achieving reliable connection and positioning of the positioning insert. During mold opening, the movable block drives the hook to move along the separation groove, causing the elastic limiting element and the separation groove to interact, thereby gradually disengaging the hook from the positioning insert. This structure ensures positioning stability during insert molding while achieving automatic separation of the positioning insert from the hook, avoiding manual disassembly of the positioning insert, reducing subsequent processing steps, improving production efficiency, and reducing wear or damage to the positioning insert caused by repeated disassembly and assembly, thereby extending the mold's service life.

[0041] In an optional embodiment, the movable block 14 is provided with a first groove 143 on the side facing the positioning insert 15, and the movable block 14 further includes a rotating shaft, the two ends of which are respectively fixed to the upper inner wall and the lower inner wall of the first groove 143. The hook 142 is sleeved on the rotating shaft so that the hook 142 rotates around the rotating shaft.

[0042] The hook 142 can rotate around the pivot, which reduces interference between the hook 142 and the edge of the slot 151 during the process of engaging the hook 142 into the slot 151, thereby reducing the engagement resistance and making the mold closing process smoother.

[0043] Furthermore, such as Figure 9 As shown, the rotating shaft includes a first rotating shaft 1451 and a second rotating shaft 1452 that are spaced apart from each other; Correspondingly, the hook 142 includes a first hook body 1421 and a second hook body 1422, the first hook body 1421 being sleeved on the first rotating shaft 1451, and the second hook body 1422 being sleeved on the second rotating shaft 1452.

[0044] The two hooks (1421, 1422) can be more stably engaged with the positioning insert 15, and the two hooks will rotate toward each other as they are engaged in the slot 151, thereby reducing the engagement resistance and making the mold closing process smoother.

[0045] Furthermore, the hook 142 also includes an elastic element 1425, which is fixed between the first hook body 1421 and the second hook body 1422.

[0046] During the process of the hook 142 being engaged in the slot 151, the first hook body 1421 and the second hook body 1422 rotate toward each other, thereby compressing the elastic element 1425. After the first hook body 1421 and the second hook body 1422 are engaged in the slot 151, the elastic force generated by the compression of the elastic element 1425 can make the first hook body 1421 and the second hook body 1422 stick tightly to the inner wall of the slot 151, making the hook 142 more stably engaged with the slot 151 and preventing the hook 142 from detaching from the slot 151.

[0047] Specifically, the elastic element 1425 can be a spring, but is not limited to this; the elastic element 1425 can also be a rubber block, etc.

[0048] In an optional embodiment, the first hook 1421 has a chamfer at one end facing the positioning insert 15, and the second hook 1422 has another chamfer at one end facing the positioning insert 15.

[0049] By chamfering the side of the hook body (1421, 1422) facing the positioning insert 15, the chamfering of the hook 142 can reduce the interference between the hook 142 and the slot 151 during the process of the hook 142 being engaged in the slot 151, thereby making the process of the hook 142 being engaged in the slot 151 smoother.

[0050] Furthermore, the end of the positioning insert 15 facing the hook 142 is also provided with a corresponding chamfer. During the process of the hook 142 being inserted into the slot 151, the chamfer on the positioning insert 15 comes into contact with the chamfer on the hook 142, thereby further reducing the interference between the hook 142 and the positioning insert 15 during the process of the hook 142 being inserted into the slot 151.

[0051] In an optional embodiment, the bottom wall of the slide 121 is provided with a second groove 1212; The second mold 12 further includes a pressure block 124, which is fixed to the bottom wall of the slide groove 121 and abuts against the side wall of the slide groove 121. The pressure block 124 and the second groove 1212 surround each other to form a third groove 1243. The movable block 14 is provided with a protruding edge 147, which is slidably located within the third groove 1243.

[0052] The slide groove 121 restricts the left-right displacement of the movable block 14 relative to the slide groove 121, and the pressure block 124 restricts the vertical displacement of the protrusion 147, thereby preventing the movable block 14 from undergoing vertical displacement. In this optional embodiment, the movable block 14 is limited to moving only back and forth along the slide groove 121, thereby avoiding the problem that the hook 142 on the movable block 14 cannot be matched with the slot 151 on the positioning insert 15 due to the movable block 14 being offset.

[0053] In an optional embodiment, the first mold 11 is provided with a mating sleeve 115, and the second mold 12 is provided with a corresponding mating post 125; When the first mold 11 and the second mold 12 are closed, the mating post 125 is inserted into the mating sleeve 115.

[0054] When the first mold 11 and the second mold 12 are closed, the mating pillar 125 and the mating sleeve 115 can play a role in alignment, so that the first mold 11 can move vertically relative to the second mold 12 when the mold is closed, avoiding the situation where the guide pillar 113 cannot drive the movable block 14 to move normally due to the oblique movement of the first mold 11.

[0055] It is understandable that the mating sleeve 115 and the mating post 125 can also be interchanged, that is, the mating post 125 is set on the first mold 11 and the mating sleeve 115 is set on the second mold 12.

[0056] Furthermore, there are multiple mating sleeves 115 and correspondingly multiple mating posts 125. The multiple mating sleeves 115 are evenly distributed on the periphery of one side of the first mold 11, and the multiple mating posts 125 are evenly distributed on the periphery of one side of the second mold 12.

[0057] Multiple mating sleeves 115 and mating pillars 125 can play a better alignment role during mold closing, thereby avoiding the situation where the first mold 11 is offset relative to the second mold 12 during the mold closing process.

[0058] Specifically, both the first mold 11 and the second mold 12 can be cuboids, and there are four mating sleeves 115 and four mating posts 125. The four mating sleeves 115 are located at the four right angles on one side of the first mold 11, and the four mating posts 125 are located at the four right angles on one side of the second mold 12.
