Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold. Background Technology

[0002] To position the workpiece for machining via a mold, molds typically include sliding inserts to prevent deformation during mold closing. Additionally, to ensure smooth removal of the workpiece from the mold after mold opening, existing technologies incorporate angled guide pillars. The cooperation between the angled guide pillars and their holes allows the sliding inserts to be close to the workpiece during mold closing and away from it during mold opening. However, the angled guide pillars and their holes can generate an upward force during mold opening, potentially causing the sliding inserts to warp and damage the product, thus affecting production yield. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mold that can improve production yield.

[0004] A mold according to an embodiment of the present invention includes an upper mold and a lower mold. The lower mold includes a mold body, a sliding insert, and a driving structure. The mold body is provided with a positioning area and an upward-facing mounting groove. The sliding insert is slidably disposed on the mold body in the horizontal direction and located on the horizontal side of the positioning area. The sliding insert is provided with an upward-facing snap-fit ​​groove. The driving structure includes a driving component and a driver connected to each other. The driver is detachably disposed in the mounting groove in the vertical direction, and the driving component is detachably disposed in the snap-fit ​​groove in the vertical direction. The driver can drive the sliding insert to move closer to or away from the positioning area through the driving component, so as to position or avoid the workpiece in the positioning area. The upper mold is used to cooperate with the lower mold to process the workpiece in the positioning area.

[0005] A mold according to an embodiment of the present utility model has at least the following technical effects: In the mold of this application, a positioning area and a mounting groove are formed on the mold body of the lower mold. The sliding insert is horizontally slidably mounted on the mold body, and the snap-fit ​​groove on the sliding insert faces upward. The driver in the drive structure is vertically mounted in the mounting groove, and the driver component in the drive structure is vertically mounted in the snap-fit ​​groove. The driver can push the sliding insert to move horizontally through the driver component. Before the upper and lower molds are closed, the driver drives the driver component connected to it to move horizontally closer to the positioning area, thereby moving the sliding insert snap-fitted to the driver component closer to the positioning area, so that the sliding insert first positions the workpiece, which is convenient for subsequent workpiece processing. After the upper and lower molds are opened, the driver drives the driver component connected to it to move horizontally away from the positioning area, thereby moving the sliding insert snap-fitted to the driver component away from the positioning area. At this time, the gap between the sliding insert and the workpiece allows the workpiece to easily disengage from the lower mold. As can be seen from the above, this application can drive the horizontally sliding slide insert through the vertically installed drive structure to achieve the positioning of the workpiece in the positioning area and facilitate the removal of the workpiece in the positioning area. This avoids the inclined guide post structure from generating a lifting force on the slide insert, effectively preventing the slide insert from dragging the workpiece due to lifting, and improving the production yield and processing stability.

[0006] According to some embodiments of the present invention, a mold has a notch on the side wall of the snap-fit ​​groove facing the driver. The driver includes a snap-fit ​​part and a connecting part connected to each other. The snap-fit ​​part is snapped into the snap-fit ​​groove in the horizontal direction, and the connecting part is connected to the driver through the notch. The driver is T-shaped.

[0007] According to some embodiments of the present invention, a mold has a sliding insert including an insert block and a connector. The insert block is located on the side of the connector block near the positioning area and is detachably connected to the connector block. The end face of the insert block near the positioning area forms a positioning surface, which is adapted to the workpiece in the positioning area.

[0008] According to some embodiments of the present invention, in a mold, one of the inserts and connectors is provided with a dovetail groove, and the other is provided with an insertion part, which is slidably inserted into the dovetail groove. The opening direction of the dovetail groove is parallel to the sliding direction of the sliding insert.

[0009] According to some embodiments of the present invention, the mold of the slide insert further includes a locking structure, which is connected to the insert and the connector respectively, and the locking structure is used to lock and fix the insert on the connector.

[0010] According to some embodiments of the present invention, a mold has a locking structure including a pin extending in a vertical direction, which is sequentially inserted into an insert and a connector.

[0011] According to some embodiments of the present invention, a mold body is provided with a horizontally extending guide groove, and a sliding insert is slidably disposed in the guide groove.

[0012] According to some embodiments of the present invention, the lower mold further includes two horizontally spaced limiting blocks, both of which are detachably disposed on the mold body, and a guide groove is formed between the two limiting blocks.

[0013] According to some embodiments of the present invention, a mold has a first limiting protrusion at one end of the limiting block near the guide groove. The first limiting protrusion extends along the extension direction of the guide groove, and a limiting groove is formed between the first limiting protrusion and the mold body. A second limiting protrusion is on the sliding insert and is slidably inserted into the limiting groove.

[0014] According to some embodiments of the present invention, a mold has multiple sets of sliding inserts and driving structures that correspond one-to-one, with the multiple sliding inserts arranged around the positioning area.

[0022] The following is for reference. Figures 1 to 5 A mold according to an embodiment of the present utility model will be described in detail.

[0023] refer to Figures 1 to 3 According to an embodiment of the present invention, a mold includes an upper mold 200 and a lower mold 100. The lower mold 100 includes a mold body 110, a sliding insert 120, and a driving structure 130. The mold body 110 is provided with a positioning area 111 and an upward-opening mounting groove 112. The sliding insert 120 is slidably disposed on the mold body 110 in the horizontal direction and is located on the horizontal side of the positioning area 111. The sliding insert 120 is provided with an upward-opening snap-fit ​​groove 120a. The driving structure 130... The device includes a drive component 131 and a driver 132 connected to each other. The driver 132 is detachably disposed in the mounting groove 112 in the vertical direction, and the drive component 131 is detachably disposed in the snap-fit ​​groove 120a in the vertical direction. The driver 132 can drive the sliding insert 120 to move closer to or away from the positioning area 111 through the drive component 131, so as to position or avoid the workpiece in the positioning area 111. The upper mold 200 is used to cooperate with the lower mold 100 to process the workpiece in the positioning area 111.

[0024] In the mold of this application, the lower mold 100 has a positioning area 111 and a mounting groove 112 on the mold body 110. The sliding insert 120 is horizontally slidably mounted on the mold body 110, and the snap-fit ​​groove 120a on the sliding insert 120 opens upward. The driver 132 in the drive structure 130 is vertically mounted in the mounting groove 112, and the driver 131 in the drive structure 130 is vertically mounted in the snap-fit ​​groove 120a. The driver 132 can push the sliding insert 120 to move horizontally through the driver 131. Before the upper mold 200 and the lower mold 100 are closed, the driver 132 drives the driver component 131 connected to it to move horizontally closer to the positioning area 111, thereby causing the sliding insert 120, which is engaged with the driver component 131, to move closer to the positioning area 111, so that the sliding insert 120 can first position the workpiece, which is convenient for subsequent processing of the workpiece; after the upper mold 200 and the lower mold 100 are opened, the driver 132 drives the driver component 131 connected to it to move horizontally away from the positioning area 111, thereby causing the sliding insert 120, which is engaged with the driver component 131, to move away from the positioning area 111. At this time, the gap between the sliding insert 120 and the workpiece allows the workpiece to easily detach from the lower mold 100. As can be seen from the above, this application can drive the horizontally sliding slide insert 120 through the vertically installed drive structure 130 to achieve the positioning of the workpiece in the positioning area 111 and facilitate the removal of the workpiece in the positioning area 111. This avoids the inclined guide post structure from generating a lifting force on the slide insert 120, effectively preventing the slide insert 120 from dragging the workpiece due to lifting, and improving the production yield and processing stability.

[0025] refer to Figures 2 to 5 In some embodiments of this utility model, the sidewall of the snap-fit ​​groove 120a is provided with a notch 120b facing the driver 132. The driving member 131 includes a snap-fit ​​portion 131a and a connecting portion 131b connected together. The snap-fit ​​portion 131a is horizontally snapped into the snap-fit ​​groove 120a, and the connecting portion 131b is connected to the driver 132 through the notch 120b. The driving member 131 is T-shaped. It can be understood that the notch 120b is provided on the sidewall of the snap-fit ​​groove 120a, the driving member 131 is designed as a T-shaped structure, and the snap-fit ​​portion 131a of the driving member 131 is horizontally snapped into the snap-fit ​​groove 120a, so that the connecting portion 131b of the T-shaped driving member 131 can be connected to the driver 132 through the notch 120b. The snap-fit ​​structure between the T-shaped driving member 131 and the sliding insert 120 is relatively simple, and the assembly and disassembly are more convenient, which improves the stability and maintainability of the driving structure 130.

[0026] like Figures 2 to 4As shown, in some embodiments of this utility model, the sliding insert 120 includes an insert 121 and a connector 122. The insert 121 is located on the side of the connector 122 near the positioning area 111 and is detachably connected to the connector 122. The end face of the insert 121 near the positioning area 111 forms a positioning surface 121a, which is adapted to the workpiece within the positioning area 111. It can be understood that the sliding insert 120 consists of an insert 121 and a connector 122. The insert 121 is located on the side of the connector 122 near the positioning area 111 and is detachably connected to the connector 122. The end face of the insert 121 forms a positioning surface 121a adapted to the shape of the workpiece. The insert 121 can be replaced for workpieces of different specifications, so that the positioning surface 121a of different inserts 121 can adapt to workpieces of different specifications, thereby improving the overall versatility and adaptability of the mold and reducing maintenance costs.

[0027] like Figure 3 and Figure 4 As shown, in some embodiments, one of the insert 121 and the connector 122 has a dovetail groove 122a, and the other has an insertion portion 121b. The insertion portion 121b is slidably inserted into the dovetail groove 122a, wherein the opening direction of the dovetail groove 122a is parallel to the sliding direction of the sliding insert 120. Specifically, the connector 122 has a dovetail groove 122a, and the insert 121 has an insertion portion 121b.

[0028] It is understood that the insert portion 121b of the insert 121 slides through the dovetail groove 122a of the connector 122, and the opening direction of the dovetail groove 122a is parallel to the sliding direction of the sliding insert 120. Therefore, when the drive structure 130 drives the connector 122 to slide in the horizontal direction, the cooperation between the dovetail groove 122a and the insert portion 121b causes the insert 121 to slide in the horizontal direction with the connector 122. The structure of the dovetail groove 122a provides a stable sliding guide, preventing the insert 121 from leaving the sliding direction during the process of sliding in the horizontal direction with the connector 122, thereby ensuring the positioning accuracy of the sliding insert 120.

[0029] like Figure 2As shown, in some embodiments, the sliding insert 120 further includes a locking structure 140, which is connected to both the insert 121 and the connector 122. The locking structure 140 is used to lock the insert 121 onto the connector 122. It is understood that by adding the locking structure 140 to the sliding insert 120 to fix the insert 121 and the connector 122 together, the possibility of relative movement between them is reduced. The locking structure 140 enhances the connection rigidity between the insert 121 and the connector 122, preventing positional changes due to vibration or force during movement or processing, thereby further ensuring the positioning accuracy of the sliding insert 120.

[0030] like Figure 2 As shown, in one embodiment, the locking structure 140 includes a pin extending vertically, which passes sequentially through the insert 121 and the connector 122. It is understood that the locking structure 140 uses a vertically extending pin, which passes sequentially through the insert 121 and the connector 122, to achieve mechanical fixation of the insert 121 and the connector 122. The pin-based locking structure 140 is simple and reliable, easy to install and remove, and provides good fixation, adapting to frequent replacement of the insert 121.

[0031] refer to Figure 2 and Figure 5 In some embodiments of this invention, the mold body 110 is provided with a horizontally extending guide groove 113, and the sliding insert 120 is slidably disposed in the guide groove 113. It is understood that the horizontally extending guide groove 113 on the mold body 110 and the sliding insert 120 slidably disposed in the guide groove 113 provide a stable sliding path for the sliding insert 120, reducing the possibility of deflection or jamming during the sliding process.

[0032] like Figure 2 and Figure 5 As shown, in some embodiments, the lower mold 100 further includes two horizontally spaced limiting blocks 150, both of which are detachably mounted on the mold body 110, and a guide groove 113 is formed between the two limiting blocks 150. It is understood that the two horizontally spaced limiting blocks 150 are detachably mounted on the mold body 110, thereby forming the guide groove 113 between them. By making the limiting blocks 150 detachable, maintenance and replacement of the limiting blocks 150 are facilitated. At the same time, the guide groove 113 formed by the limiting blocks 150 has a simple structure and low manufacturing cost.

[0033] like Figure 3 and Figure 5As shown, in one embodiment, the limiting block 150 has a first limiting protrusion 151 at one end near the guide groove 113. The first limiting protrusion 151 extends along the extension direction of the guide groove 113, and a limiting groove 100a is formed between the first limiting protrusion 151 and the mold body 110. The sliding insert 120 has a second limiting protrusion 122b, which slidably passes through the limiting groove 100a. It can be understood that the first limiting protrusion 151 at one end of the limiting block 150 near the guide groove 113, the limiting protrusion forming the limiting groove 100a with the mold body 110, and the second limiting protrusion 122b slidably passing through the limiting groove 100a, further enhances the movement stability of the sliding insert 120 by setting a double-protrusion limiting structure, reducing the possibility of the sliding insert 120 lifting or deviating during sliding.

[0034] refer to Figure 1 and Figure 5 In some embodiments of this utility model, multiple sets of sliding inserts 120 and driving structures 130 are provided in a one-to-one correspondence, with multiple sliding inserts 120 arranged around the positioning area 111. It can be understood that with multiple sets of sliding inserts 120 and driving structures 130 arranged around the positioning area 111, each set independently drives the sliding insert 120 to slide horizontally. Through the coordinated work of multiple sets of sliding inserts 120, multi-directional positioning of the workpiece can be achieved, thereby improving the stability of workpiece positioning.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
