Technical Field

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

[0002] Traditional molds include a base plate, an upper mold, a lower mold, an upper guard plate, and a lower guard plate. The upper and lower molds are interlocked and work together to process materials such as pipes inside the mold cavity. The upper and lower guard plates prevent employees from putting their hands into the mold cavity from the side, which could lead to safety accidents.

[0003] Traditional molds lack a material handling and pulling structure after tube forming, requiring the use of auxiliary tools such as clamps to remove the material. In other words, during the material handling process of transmission molds, operators must reach their hands into the mold cavity from the mold end face to remove the material, which is not only labor-intensive but also poses safety hazards. Alternatively, operators can use auxiliary tools to remove the material, which further increases the labor intensity.

[0004] In view of the problems of the prior art, those skilled in the art urgently need a mold material handling device and a mold. Utility Model Content

[0008] In some embodiments, an elastic element is also included, one end of which is connected to the slider assembly and the other end is a fixed end; the pushing part can overcome the elastic force of the elastic element and push the slider to slide away from the cavity; the slider assembly can slide towards the cavity under the elastic force of the elastic element.

[0009] In some embodiments, one end of the material-taking rod extending into the cavity is provided with a top material portion; at least a portion of the top material portion is located between the lower part of the material and the inner wall of the cavity and supports the material; the slider assembly slides away from the cavity, causing the top material portion to disengage from the material and be opposite to the end of the material; the slider assembly slides towards the cavity, causing the top material portion to abut against the end of the material and push the material.

[0010] In some embodiments, a rolling element is further included, which is rotatably connected to the slider assembly; the pushing part has an inclined surface, which contacts the rolling element and pushes the slider assembly to slide through the inclined surface.

[0011] In some embodiments, the inclined surface has a first end close to the upper mold and a second end away from the upper mold, the distance between the first end and the bottom plate of the mold is smaller than the distance between the second end and the bottom plate; under the pushing action of the pushing part, the rolling body can roll along the inclined surface from the first end to the second end.

[0012] In some embodiments, a slide rail is also included, which is disposed on the base plate of the mold, and the slider assembly is slidably connected to the slide rail; and / or the slider assembly can compress or stretch the elastic element by sliding in a direction away from the cavity.

[0013] In some embodiments, the slider assembly includes a first connecting block with two connecting lugs at its top, the rolling element being a roller with its two ends rotatably connected to the two connecting lugs respectively; and / or the inclined surface is an inclined plane or an inclined curved surface.

[0014] In some embodiments, the slider assembly includes a second connecting block, the two picking rods are arranged in parallel and both are connected to the second connecting block, and the distance between the two picking rods is adjustable.

[0015] In some embodiments, the slider assembly further includes a first slider, a second slider, and a screw; the second connecting block has an assembly groove and the screw is rotatably connected within the assembly groove, at least one end of the screw can pass through the sidewall of the assembly groove and extend outward; the screw has a first threaded segment and a second threaded segment, and the threads of the first threaded segment and the second threaded segment have opposite directions; the first slider has a first threaded hole and is correspondingly connected to the first threaded segment, and the second slider has a second threaded hole and is correspondingly connected to the second threaded segment; one end of each of the two picking rods is respectively connected to the first slider and the second slider.

[0016] In a second aspect, the present invention also provides a mold, including the above-mentioned mold material handling device.

[0017] The present invention achieves the following technical advantages over the prior art:

[0018] The mold material handling device of this utility model has a pushing part connected to the upper mold and a material handling rod connected to the slider assembly. One end of the material handling rod can extend into the cavity. When the upper mold drives the pushing part to move closer to the lower mold, the pushing part can push the slider assembly to slide away from the cavity and drive the material handling rod away from the material inside the cavity to avoid affecting the mold's processing of the material. When the upper mold drives the pushing part to move away from the lower mold, the slider assembly can slide back to its original position and drive one end of the material handling rod to push the formed material inside the cavity, so that at least a part of the material is outside the cavity. At this time, the operator can manually handle the material without the aid of auxiliary tools. That is, the operator does not need to put his hand into the cavity to handle the material or use auxiliary tools to handle the material, which can reduce labor intensity and avoid safety hazards.

[0019] Furthermore, this invention enables the slider assembly to return to its original position by setting an elastic element. One end of the elastic element is connected to the slider assembly, and the other end is a fixed end. When the pushing part moves with the upper mold towards the lower mold, the pushing part needs to overcome the elastic force of the elastic element and push the slider assembly. That is, during the process of the pushing part pushing the slider assembly, the elastic deformation of the elastic element will change accordingly. When the pushing part moves with the upper mold away from the lower mold, the elastic restoring force of the elastic element can drive the slider assembly to slide back to its initial position. Thus, this invention can automatically control the slider assembly to return to its original position and drive the material pick-up rod to push the material to assist in material picking by setting an elastic element.

[0020] Furthermore, the pushing part of this utility model has an inclined surface, and a rolling element is provided on the slider assembly. The pushing part makes rolling contact with the rolling element through the inclined surface and pushes the slider assembly to slide, which can avoid jamming during the pushing process and reduce wear.

[0021] Furthermore, the distance between the two picking rods of this invention can be adjusted to accommodate materials of different sizes. Specifically, since the first and second threaded sections of the screw have different thread directions, when the screw rotates, the first slider connected to the first threaded section and the second slider connected to the second threaded section move in opposite directions, thereby changing the distance between the two sliders, and consequently changing the distance between the two picking rods. Thus, by configuring the two picking rods with an adjustable distance, this invention can expand the applicability of the mold picking device. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The purpose of this utility model is to provide a mold material handling device and a mold to solve the problems existing in the prior art. It can assist in material handling after the material is formed, so as to reduce labor intensity and avoid safety hazards.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] This embodiment provides a mold material handling device, such as... Figure 1 and Figure 2 As shown, the mold includes a material-taking rod 1, a slider assembly 2, and a pushing part 3; the mold involved includes an upper mold 101, a lower mold 102, an upper guard plate 104, a lower guard plate 105, and a base plate 106; the upper mold 101 and the lower mold 102 are correspondingly engaged and have a cavity 103 between them. During processing, the material 200 is placed in the cavity 103, and the upper mold 101 and the lower mold 102 are correspondingly engaged to process the material 200; the upper guard plate 104 and the lower guard plate 105 are correspondingly arranged on the side of the mold to prevent the operator from putting their hand into the cavity 103 from the side.

[0033] Continue reading Figure 1 One end of the picking rod 1 is connected to the slider assembly 2, and the other end of the picking rod 1 can extend into the cavity 103. The pushing part 3 is fixedly connected to the end of the upper mold 101. The upper mold 101 can drive the pushing part 3 to slide towards the lower mold 102. During this process, the pushing part 3 can push the slider assembly 2 to slide away from the cavity 103. At the same time, the slider assembly 2 drives the picking rod 1 to move together, so that the picking rod 1 moves away from the workpiece 200, and one end of the picking rod 1 is in a corresponding position with the end of the workpiece 200. Therefore, when the upper mold 101 and the lower mold 102 are engaged to process the workpiece 200, the picking rod 1 does not affect the processing.

[0034] The upper mold 101 can also drive the pushing part 3 to slide away from the lower mold 102. During this process, the slider assembly 2 can slide towards the cavity 103. At the same time, the slider assembly 2 drives the picking rod 1 to move together, so that one end of the picking rod 1 that extends into the cavity 103 abuts against the end of the material 200 and pushes the formed material 200, pushing at least a part of the material 200 out of the cavity 103. Thus, the operator does not need to put his hand into the cavity 103 to pick up the material, which improves the safety of operation and reduces labor intensity.

[0035] It should be noted that the material 200 in this embodiment can be a tube or a material of other shapes; and this embodiment is described by taking the connection between the push part 3 and the end of the upper mold 101 as an example. Those skilled in the art can also adjust the connection position between the push part 3 and the upper mold 101; this utility model does not make any specific limitations in this regard.

[0036] In some embodiments of this example, the mold material handling device further includes an elastic element 4. One end of the elastic element 4 is connected to the slider assembly 2, and the other end is a fixed end. The elastic element 4 is used to apply an elastic force to the slider assembly 2. When the pushing part 3 moves toward the lower mold 102, the pushing part 3 needs to overcome the elastic force of the elastic element 4 and push the slider assembly 2 to slide away from the cavity 103. When the pushing part 3 moves away from the lower mold 102, the elastic restoring force of the elastic element 4 can drive the slider assembly 2 to slide toward the cavity 103 to the initial position, thereby driving the material handling rod 1 to push the material 200.

[0037] It should be noted that in this embodiment, the sliding of the slider assembly 2 away from the cavity 103 can compress the elastic element 4, and the elastic restoring force of the elastic element 4 is a pushing force that pushes the slider assembly 2 to slide. Those skilled in the art can also specifically adjust the connection position of the fixed end of the elastic element 4 so that the sliding of the slider assembly 2 away from the cavity 103 can stretch the elastic element 4, and the elastic restoring force of the elastic element 4 is a pulling force that pulls the slider assembly 2 to slide.

[0038] In some embodiments of this utility model, a top material part 11 is provided at one end of the material taking rod 1 that extends into the cavity 103. At least a portion of the top material part 11 is located between the lower part of the material 200 and the inner wall of the cavity 103, thereby supporting the material 200. At this time, the outer peripheral wall of the material 200 is not completely in contact with the inner wall of the cavity 103. When the slider assembly 2 slides away from the cavity 103, the top material part 11 disengages from the outer peripheral wall of the material 200, thereby completely fitting the outer peripheral wall of the material 200 with the inner wall of the cavity 103. Due to the change in the position of the material 200, the top material part 11 and the end of the material 200 are in a relative position. When the slider assembly 2 slides toward the cavity 103, the top part 11 can abut against the end of the material 200 and push the material 200 toward the outside of the cavity 103, pushing at least a part of the material 200 to be located outside the cavity 103, so that the operator can pick up the material.

[0039] In some embodiments of this utility model, a rolling element 5 is also included, which is disposed on the slider assembly 2 and rotatably connected to the slider assembly 2; the pushing part 3 has an inclined surface 31, which makes rolling contact with the rolling element 5 through the inclined surface 31 and can push the rolling element 5 and the slider assembly 2 as a whole to move.

[0040] It should be noted that in this embodiment, the inclined surface 31 is an inclined planar structure. Those skilled in the art can also set the inclined surface 31 as an inclined curved surface structure. This utility model does not make any specific limitations.

[0041] The inclined surface 31 has a first end close to the upper mold 101 and a second end away from the upper mold 101, wherein the distance between the first end of the inclined surface 31 and the base plate 106 is smaller than the distance between the second end of the inclined surface 31 and the base plate 106, so that when the pushing part 3 pushes the rolling body 5, the rolling body 5 can roll from the first end to the second end along the inclined surface 31, and the rolling body 5 and the slider assembly 2 as a whole move away from the cavity 103.

[0042] In some embodiments of this utility model, such as Figure 2 As shown, the slider assembly 2 includes a first connecting block 21, a second connecting block 22 and a third slider 26. The top of the first connecting block 21 is provided with two connecting lugs 211, and the rolling element 5 is a roller. The two ends of the roller are rotatably connected to the two connecting lugs 211 respectively.

[0043] The second connecting block 22 is connected and fixed to the first connecting block 21. There are two material picking rods 1. The two material picking rods 1 are arranged in parallel. One end of the two material picking rods 1 extends into the cavity 103 and can contact both sides of the outer peripheral wall of the material 200. The other end of the two material picking rods 1 is connected and fixed to the second connecting block 22.

[0044] A slide rail 6 is provided on the base plate 106 of the mold, the third slider 26 is slidably connected to the slide rail 6, and the bottom of the first connecting block 21 is connected and fixed to the third slider 26.

[0045] It should be noted that this embodiment is illustrated by setting the rolling element 5 as a roller. Those skilled in the art can specifically set the structure of the rolling element 5. This utility model does not make specific limitations, as long as the effect of rolling contact between the rolling element 5 and the inclined surface 31 can be achieved.

[0046] In some embodiments of this utility model, a fixing rod 7 is also included. One end of the fixing rod 7 is connected and fixed to the end of the base plate 106, and the other end of the fixing rod 7 is connected and fixed to one end of the elastic member 4.

[0047] It should be noted that those skilled in the art can also configure it so that one end of the elastic element 4 is connected and fixed to the base plate 106; and the elastic element 4 in this embodiment can be a spring or other elastic element.

[0048] When using the mold feeding device in this embodiment:

[0049] In the initial position, the ejector part 11 of the ejector rod 1 is located inside the cavity 103 and supports the workpiece 200. When the upper mold 101 and the lower mold 102 are engaged to process the workpiece 200, the pusher part 3 can move with the upper mold 101 toward the lower mold 102. The inclined surface 31 of the pusher part 3 contacts the rolling element 5 and overcomes the elastic force of the elastic element 4, pushing the slider assembly 2 to slide away from the cavity 103. At the same time, the ejector part 11 of the ejector rod 1 can disengage from the workpiece 200, and the workpiece 200 will undergo a certain displacement and fit against the inner wall of the cavity 103. At this time, the ejector part 11 and the end of the workpiece 200 are in corresponding positions.

[0050] When the upper mold 101 separates from the lower mold 102 after molding, the pushing part 3 can move away from the lower mold 102 along with the upper mold 101. At this time, the elastic force of the elastic element 4 can drive the slider assembly 2 to slide towards the cavity 103 to the initial position. At the same time, the ejector part 11 of the picking rod 1 can abut against the end of the material 200 and push the material 200 outward, so that at least a part of the material 200 is located outside the cavity 103. At this time, the operator can pick up the material without putting his hand into the cavity 103, which improves safety and reduces labor intensity.

[0051] Example 2

[0052] This embodiment provides a mold material handling device, such as... Figure 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the distance between the two material picking rods 1 in this embodiment can be adjusted.

[0053] Specifically, the slider assembly 2 also includes a first slider 23, a second slider 24, and a screw 25. The second connecting block 22 has an assembly groove 221 inside, in which the screw 25 is installed. Both ends of the screw 25 are rotatably connected to the side wall of the assembly groove 221. One end of the screw 25 is the driving end and can pass through the side wall of the assembly groove 221 and extend outward. The length direction of the screw 25 is perpendicular to the length direction of the picking rod 1.

[0054] The screw 25 has a first threaded section 251 and a second threaded section 252, and the threads of the first threaded section 251 and the second threaded section 252 have opposite directions of rotation, that is, the thread of the first threaded section 251 is left-handed and the thread of the second threaded section 252 is right-handed, or the thread of the first threaded section 251 is right-handed and the thread of the second threaded section 252 is left-handed; the first slider 23 has a first threaded hole and is threadedly connected to the first threaded section 251, and the second slider 24 has a second threaded hole and is threadedly connected to the second threaded section 252; one end of each of the two feed rods 1 is respectively connected to the first slider 23 and the second slider 24.

[0055] When the drive screw 25 rotates, the first slider 23 and the second slider 24 move in opposite directions, that is, the first slider 23 and the second slider 24 can separate at both ends or move closer to the middle, thereby adjusting the distance between the two picking rods 1. Thus, the mold picking device of this utility model can be adapted to materials 200 of different sizes and has a wide range of applications.

[0056] This utility model also provides a mold, including the mold material handling device in Embodiment 1 or Embodiment 2 above.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
