Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick clamping technology, and more specifically, it relates to a mold positioning assembly for quick clamping. Background Technology
[0002] The mold positioning assembly is a key component in the mold clamping and processing process. It is used to ensure the precise position of the mold on the equipment and plays an important role in ensuring product quality and improving production efficiency.
[0003] Currently, in the use of foaming molds, quick clamping systems are one of the key factors in improving production efficiency. Since foaming molds are usually used for mass production of foamed products, such as car seats, frequent mold changes and installations require efficient clamping methods. Quick clamping can not only reduce mold installation time, but also ensure the positioning accuracy of the mold on the equipment, thereby ensuring the consistency of product quality.
[0004] However, existing quick clamping mechanisms achieve quick clamping by directly inserting locating pins into locating slots. But this type of clamping mechanism has high requirements for the locating pins and locating slots, that is, the two must be highly compatible. However, the locating slots may develop tiny burrs or deformations during long-term use. At this time, the locating pins and locating slots will not be compatible, and the quick clamping operation will be affected. This paper proposes a mold locating assembly for quick clamping to improve the existing problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mold positioning assembly for quick clamping.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A mold positioning assembly for quick clamping includes a lower mold assembly, wherein a plurality of positioning components are disposed inside the lower mold assembly, the positioning components being used to assist in the positioning and clamping of the mold.
[0008] The lower mold assembly includes a lower mold frame, the lower mold frame has a lower cavity inside, the lower cavity has a number of ribs inside, and the ribs have a number of placement grooves.
[0009] Each of the positioning components includes a buckle, and a positioning pin is provided below the buckle. The shape of the positioning pin is adapted to the shape of the buckle, and the positioning pin is disposed inside the placement groove.
[0010] By adopting the above technical solution, the structure of matching the placement groove with the positioning pin and the buckle with the positioning pin is set to meet the needs of quick clamping of the foaming mold. When the foaming mold is used, the buckle and the positioning pin can be clamped quickly.
[0011] The present invention is further configured such that: the buckle includes a buckle cover, the buckle cover is composed of two sets of trapezoidal components arranged opposite each other, and the trapezoidal components are provided with several through holes.
[0012] The present invention is further configured such that: a clamp is provided on the top of the cover, and a U-shaped groove is provided through the top of the clamp.
[0013] By adopting the above technical solution, the U-shaped groove not only serves as a quick clamping mechanism but also plays an important role in the covering process. After the foaming work is completed, the cover is wrapped around the outside of the foam body. At this time, a steel wire can be clamped in the middle of the U-shaped groove. One side of the steel wire is sewn to the cover, and the other side is clamped inside the U-shaped groove. Due to the limiting effect of the U-shaped groove, the steel wire will pull the cover and keep it taut. Compared with the ordinary method of setting the steel wire on the outside of the foam body and then connecting the steel wire to the cover with a C-ring, the structure of setting the steel wire by the U-shaped groove can clamp the steel wire into the U-shaped groove by pressing. With the U-shaped groove fixing the steel wire, the steel wire tightens the cover. The structure is simple, convenient and quick.
[0014] The present invention is further configured such that: the positioning pin includes a positioning block, the top of the positioning block has a through groove, and the inner side of the groove has a chamfer.
[0015] The present invention is further configured such that: a limiting rib is provided at the middle position of the groove, and the shape of the limiting rib is adapted to the shape of the U-shaped groove.
[0016] By adopting the above technical solution, a chamfer is also provided on the outer side of the limiting rib. During the rapid clamping process of the foaming mold, the U-shaped groove engages with the limiting rib, and the end of the clamp contacts the groove. Since the limiting rib and the U-shaped groove need to be matched with high precision, the edges and corners of the limiting rib may develop some small burrs or deformations due to processing errors or long-term use. With the chamfer, when the U-shaped groove enters the limiting rib, the edges and corners of the U-shaped groove can engage with the limiting rib along the slope of the chamfer, avoiding damage to the limiting rib caused by direct collision between the edges and corners of the limiting rib and the edge of the U-shaped groove. In addition, the chamfer provided on the inner side of the groove also avoids direct contact between the groove and the clamp, reducing the possibility of clamp damage and increasing the service life of the buckle and positioning pin.
[0017] The present invention is further configured such that: two sets of fixing holes are symmetrically opened through the top of the positioning block; the positioning block is disposed inside the placement groove; and the positioning block and the placement groove are connected by bolts passing through the two sets of fixing holes.
[0018] By adopting the above technical solution, the positioning pin is set inside the placement groove, and the positioning pin is fixedly connected to the placement groove with bolts. In addition, a buckle is set on the top of the positioning pin, which enables quick clamping of the positioning pin. This avoids direct wear on the foaming mold placement groove during quick clamping, reduces damage to the foaming mold, and increases the service life of the foaming mold. At the same time, the bolt fixing also facilitates the replacement of the positioning pin.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. The positioning pin is set inside the placement groove, and the positioning pin is fixed to the placement groove with bolts. In addition, a buckle is set on the top of the positioning pin. The buckle and the positioning pin can achieve quick clamping, which avoids direct wear on the foaming mold placement groove during quick clamping, reduces damage to the foaming mold, and increases the service life of the foaming mold. At the same time, the bolt fixing also facilitates the replacement of the positioning pin.
[0021] 2. By setting a U-shaped groove limiting steel wire structure, the steel wire can be clamped into the U-shaped groove of the knife by pressing. With the steel wire fixed in the U-shaped groove, the steel wire tension sleeve is tightened. The structure is simple, convenient and quick. Attached Figure Description

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0031] Example 1, please refer to Figure 1-5 The present invention provides the following technical solution:
[0032] See Figure 1 A mold positioning assembly for quick clamping includes a lower mold assembly 1, and a plurality of positioning components 2 are provided inside the lower mold assembly 1. The positioning components 2 are used to assist in the positioning and clamping of the mold.
[0033] See Figure 2 The lower mold assembly 1 includes a lower mold frame 11, and a lower cavity 12 is provided inside the lower mold frame 11. A number of ribs 13 are provided inside the lower cavity 12, and a number of placement grooves are provided on the ribs 13.
[0034] See Figure 3 Each positioning component 2 includes a buckle 21, and a positioning pin 22 is provided below the buckle 21. The shape of the positioning pin 22 is adapted to the shape of the buckle 21. The positioning pin 22 is set inside the placement groove. By setting the placement groove and the positioning pin 22 to be adapted, and the buckle 21 and the positioning pin 22 to be adapted, the need for quick clamping of the foaming mold is met. When the foaming mold is used, the buckle 21 and the positioning pin 22 can be clamped quickly.
[0035] See Figure 4 The buckle 21 includes a cover 211, which is composed of two sets of trapezoidal components arranged opposite each other. Several through holes are provided through the trapezoidal components to facilitate the penetration of foaming material and achieve a better foaming effect.
[0036] See Figure 4The top of the cover 211 is equipped with a clamp 212, and a U-shaped groove 213 is opened through the top of the clamp 212. In addition to its function of quick clamping, the U-shaped groove 213 also plays an important role in the covering process. After the foaming work is completed, the cover is wrapped around the outside of the foam body. At this time, a steel wire can be clamped in the middle of the U-shaped groove 213. One side of the steel wire is sewn to the cover, and the other side is clamped inside the U-shaped groove 213. Due to the limiting effect of the U-shaped groove 213, the steel wire will pull the cover and keep the cover taut. Compared with the ordinary method of setting the steel wire on the outside of the foam body and then connecting the steel wire to the cover with a C-ring, the structure of the U-shaped groove 213 limiting the steel wire, while fixing the steel wire, keeps the steel wire taut and the cover tight. The structure is simple, convenient and quick.
[0037] See Figure 5 The positioning pin 22 includes a positioning block 221, and a groove 222 is provided through the top of the positioning block 221. A chamfer is provided on the inner side of the groove 222.
[0038] See Figure 5 A limiting rib 224 is provided in the middle of the groove 222. The shape of the limiting rib 224 is adapted to the shape of the U-shaped groove 213. The outer side of the limiting rib 224 is also chamfered. During the rapid clamping process of the foaming mold, the U-shaped groove 213 and the limiting rib 224 are engaged, and the end of the clamp 212 contacts the groove 222. Since the limiting rib 224 and the U-shaped groove 213 need to be matched with high precision, the edges and corners of the limiting rib 224 may develop some small burrs due to processing errors or during long-term use. Alternatively, it can be deformed, resulting in a chamfer. When the U-shaped groove 213 enters the limiting rib 224, the corners of the U-shaped groove 213 can engage with the limiting rib 224 along the chamfered slope, avoiding damage to the limiting rib 224 due to direct collision between the corners of the limiting rib 224 and the edge of the U-shaped groove 213. In addition, the chamfer on the inner side of the groove 222 also avoids direct contact between the groove 222 and the clamp 212, reducing the possibility of damage to the clamp 212 and increasing the service life of the buckle 21 and the positioning pin 22.
[0039] See Figure 5 The top of the positioning block 221 has two sets of fixing holes 223 symmetrically through it. The positioning block 221 is set inside the placement groove. The positioning block 221 and the placement groove are connected by bolts through the two sets of fixing holes 223.
[0040] By setting up a structure that fixes the positioning pin 22 with bolts, the positioning pin 22 can be directly replaced when the limiting rib 224 is damaged.
[0041] The positioning pin 22 is set inside the placement groove, and the positioning pin 22 is fixedly connected to the placement groove with bolts. In addition, a buckle 21 is set on the top of the positioning pin 22. The buckle 21 and the positioning pin 22 can achieve quick clamping, which avoids direct wear on the foaming mold placement groove during quick clamping, reduces damage to the foaming mold, and increases the service life of the foaming mold.
[0042] Specifically, when the foaming mold is quickly clamped, the positioning block 221 is first fixed into the placement groove by bolts, then the U-shaped groove 213 is inserted into the limiting rib 224 to complete the clamping work, and then the foaming material is poured in to start foaming and shaping.
[0043] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
