Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, and in particular to a novel split-type cavity module and EPP foaming mold. Background Technology
[0002] Currently, in the production of EPP enclosures, foaming molds with integrated cavity modules are typically used. These molds have high manufacturing costs, require the cutting of large-sized steel pieces, and have high maintenance costs. Once the module is damaged, it can only be repaired or replaced as a whole. In addition, these molds cannot adapt to the rapid changeover requirements of enclosures with multiple specifications.
[0003] In existing technologies, the production of EPP enclosures also utilizes foaming molds with separate cavity modules. These molds reduce manufacturing and maintenance costs and can adapt to the rapid changeover requirements of various enclosure sizes. The inserts of these cavity modules are typically fixed together with bolts. While this method ensures a secure connection between the inserts, it has the following significant drawbacks in EPP enclosure production:
[0004] (1) Expansion and deformation: The preload of the bolts will decrease, and the expansion pressure of EPP high-pressure foaming will cause displacement between the inserts, resulting in the expansion of the splicing seam between the inserts, causing flash to appear at the corners of the EPP box, reducing the product yield, and requiring manual repair to increase costs.
[0005] (2) Thermal deformation: High-pressure foaming of EPP will cause thermal deformation of the insert, which will eventually lead to the wall thickness of the finished EPP box being out of tolerance.
[0006] (3) Frequent maintenance: The preload of the bolts will decrease periodically, so frequent maintenance is required, which increases maintenance costs. Utility Model Content
[0007] The purpose of this utility model is to provide a novel split-type cavity module and EPP foaming mold, which aims to solve or at least partially solve the shortcomings of the above-mentioned background technology. It can not only prevent the splicing seam between the inserts from widening and causing instability of precision during high-pressure foaming expansion of EPP, but also prevent the inserts from undergoing thermal deformation and causing instability of precision, thereby ensuring the high quality of the finished EPP box.

Each end of the first insert has a first mating groove, and the end of the second insert extends into the first mating groove. The upper module also includes a first locking block and a first anti-expansion strip. The first locking block is located on the outside of the connection between the first and second inserts and is used to lock the first and second inserts. The first anti-expansion strip is located on the outer side of the outer wall of the first and second inserts. To prevent deformation of the first and second inserts; the lower mold assembly includes a second forming frame and a base plate, the second forming frame and the base plate forming a lower cavity, the second forming frame including two third inserts and two fourth inserts, the two third inserts and the two fourth inserts being alternately connected end to end, the two ends of the third inserts being respectively provided with second mating grooves, the end of the fourth inserts extending into the second mating grooves, the lower mold assembly also includes a second locking block and a second anti-expansion strip, the second locking block being located on the outside of the connection between the third insert and the fourth insert and used to lock the third insert and the fourth insert, the second anti-expansion strip being located on the outer side wall of the third insert and the fourth insert and used to prevent deformation of the third insert and the fourth insert; when the mold is closed, the upper cavity and the lower cavity together form a mold cavity.
[0009] Furthermore, the cross-sections of the first locking block and the second locking block are both U-shaped. The first locking block has two first abutting parts and a first connecting part connecting the two first abutting parts. The two first abutting parts abut against the first insert and the second insert, respectively. The second locking block has two second abutting parts and a second connecting part connecting the two second abutting parts. The two second abutting parts abut against the third insert and the fourth insert, respectively.
[0010] Furthermore, the outer side wall of the second insert is recessed with a first locking groove that mates with the first abutment; the outer side wall of the fourth insert is recessed with a second locking groove that mates with the second abutment.
[0011] Furthermore, the first connecting part is fixedly connected to the first insert and the second insert respectively by fasteners; the second connecting part is fixedly connected to the third insert and the fourth insert respectively by fasteners.
[0012] Furthermore, the first insert and the second insert are connected by a snap-fit connection. The first insert has a first slot recessed at the first mating groove, and the two ends of the second insert are respectively provided with first blocks that mate with the first slot. The third insert and the fourth insert are connected by a snap-fit connection. The third insert has a second slot recessed at the second mating groove, and the two ends of the fourth insert are respectively provided with second blocks that mate with the second slot.
[0013] Furthermore, the first insert and the second insert are fixedly connected by bolts.

The third insert and the fourth insert are fixedly connected by bolts. The two ends of the third insert have a second connecting hole extending outward from the second mating groove, and the fourth insert has a second screw hole corresponding to the second connecting hole.
[0014] Furthermore, both the first locking block and the second locking block are made of SCM435 alloy steel.
[0015] Furthermore, both the first and second anti-expansion strips are made of SCM435 alloy steel.
[0016] Furthermore, the first forming frame, the second forming frame, the top plate, and the bottom plate are all made of 5083 aluminum alloy.
[0017] This utility model also provides an EPP foaming mold, including the above-mentioned novel split cavity module.
[0018] This utility model provides a novel split-type cavity module. Through the cooperation of the first mating groove and the second insert, the splicing between the first and second inserts is stable, preventing positional displacement between the first and second inserts during EPP high-pressure foaming expansion. By setting a first locking block at the splice of the first and second inserts, it prevents the splice seam from widening and causing instability in precision during EPP high-pressure foaming expansion. By setting first anti-expansion strips on the first and second inserts respectively, it prevents thermal deformation of the first molding frame from causing instability in precision. The second mating groove and the fourth... The interlocking of the inserts ensures a stable connection between the third and fourth inserts, preventing positional shifts during EPP high-pressure foaming expansion. A second locking block at the joint between the third and fourth inserts prevents the seam from widening and causing instability in precision during EPP high-pressure foaming expansion. Second anti-expansion strips on both the third and fourth inserts prevent thermal deformation of the second molding frame, thus preventing instability in precision. Therefore, this novel split-type cavity module ensures the dimensional accuracy of both the upper and lower modules, improving product yield. Attached Figure Description

[0046] As described above, the novel split-type cavity module provided by this utility model, through the cooperation of the first mating groove 113 and the second insert 112, ensures a stable splicing between the first insert 111 and the second insert 112, preventing positional displacement between the first insert 111 and the second insert 112 during EPP high-pressure foaming expansion; by providing a first locking block 14 at the splicing point of the first insert 111 and the second insert 112, it prevents the splicing seam between the first insert 111 and the second insert 112 from widening and causing instability in precision during EPP high-pressure foaming expansion; by providing first anti-expansion strips 15 on the first insert 111 and the second insert 112 respectively, it prevents thermal deformation of the first molding frame 11 from causing instability in precision; through the second mating groove 213 and the second insert 112...

Second anti-expansion strips 25 are provided on the third insert 211 and the fourth insert 212 respectively to prevent thermal deformation of the second molding frame 21 and causing instability in precision. Therefore, this novel split-type cavity module can guarantee the dimensional accuracy of the upper module 10 and the lower module 20, thereby improving product yield.
[0047] Please see Figure 3 , Figure 4 , Figure 7 and Figure 8 The cross-sections of the first locking block 14 and the second locking block 24 are both U-shaped. The first locking block 14 has two first abutting portions 141 and a first connecting portion 142 connecting the two first abutting portions 141. The two first abutting portions 141 abut against the first insert 111 and the second insert 112 respectively to lock the first insert 111 and the second insert 112, thereby preventing the joint between the first insert 111 and the second insert 112 from expanding during EPP high-pressure foaming expansion. The second locking block 24 has two second abutting portions 241 and a second connecting portion 242 connecting the two second abutting portions 241. The two second abutting portions 241 abut against the third insert 211 and the fourth insert 212 respectively to lock the third insert 211 and the fourth insert 212, thereby preventing the joint between the third insert 211 and the fourth insert 212 from expanding during EPP high-pressure foaming expansion.
[0048] Furthermore, the outer wall of the second insert 112 is recessed with a first locking groove 116 that mates with the first abutment portion 141. The two first abutment portions 141 of each first locking block 14 abut against the outer wall of the first insert 111 and the groove wall of the first locking groove 116, respectively. The outer wall of the fourth insert 212 is recessed with a second locking groove 216 that mates with the second abutment portion 241. The two second abutment portions 241 of each second locking block 24 abut against the outer wall of the third insert 211 and the groove wall of the second locking groove 216, respectively.
[0049] More specifically, the first connecting part 142 is fixedly connected to the first insert 111 and the second insert 112 respectively by fasteners. The first connecting part 142 has a first fixing hole 143 and a second fixing hole 144. The first insert 111 and the second insert 112 have a first mounting hole 1111 and a second mounting hole 1121 respectively corresponding to the first fixing hole 143 and the second fixing hole 144. The fastener is inserted into the first fixing hole 143 and screwed into the first mounting hole 1111. The fastener is inserted into the second fixing hole 144 and screwed into the second mounting hole 1121, so as to fix the first locking block 14 on the first molding frame 11.
[0050] The second connecting part 242 is fixedly connected to the third insert 211 and the fourth insert 212 respectively by fasteners. The second connecting part 242 is provided with a third fixing hole 243 and a fourth fixing hole 244. The third insert 211 and the fourth insert 212 are provided with a third mounting hole 2111 and a fourth mounting hole 2121 respectively corresponding to the third fixing hole 243 and the fourth fixing hole 244. The fastener is inserted into the third fixing hole 243 and screwed into the third mounting hole 2111, and the fastener is inserted into the fourth fixing hole 244 and screwed into the fourth mounting hole 2121, so as to fix the second locking block 24 on the second molding frame 21.
[0051] Furthermore, please refer to Figure 5 , Figure 6 , Figure 9 and Figure 10The first insert 111 and the second insert 112 are connected by a snap-fit. The first insert 111 has a first slot 114 recessed at the first mating groove 113. The two ends of the second insert 112 are respectively provided with first blocks 115 that mate with the first slot 114. The first insert 111 and the second insert 112 are more stably spliced by the snap-fit of the first slot 114 and the first blocks 115, so as to prevent the precision instability between the first insert 111 and the second insert 112 during the high-pressure foaming expansion of EPP. The third insert 211 and the fourth insert 212 are connected by a snap-fit connection. The third insert 211 has a second slot 214 recessed at the second mating groove 213. The two ends of the fourth insert 212 are respectively provided with second blocks 215 that mate with the second slot 214. The snap-fit connection between the third insert 211 and the fourth insert 212 through the second slot 214 and the second blocks 215 achieves a more stable splicing of the third insert 211 and the fourth insert 212, so as to prevent the precision instability between the third insert 211 and the fourth insert 212 during EPP high-pressure foaming expansion.
[0052] For more details, please see Figure 2 , Figure 4 and Figure 8 The outer walls of the first insert 111, the second insert 112, the third insert 211, and the fourth insert 212 are all provided with reinforcing ribs 30. The reinforcing ribs 30 can disperse stress concentration, resist bending and torsion, and further prevent the first molding frame 11 and the second molding frame 21 from thermal deformation, which would lead to instability in precision.
[0053] In this embodiment, the first locking block 14, the second locking block 24, the first anti-expansion strip 15, and the second anti-expansion strip 25 are all made of SCM435 alloy steel. SCM435 alloy steel has high strength and good heat resistance stability, preventing the first locking block 14 and the second locking block 24 from breaking or deforming due to thermal expansion during EPP high-pressure foaming, thereby effectively preventing the first molding frame 11 and the second molding frame 21 from losing precision due to foaming expansion; and preventing the first anti-expansion strip 15 and the second anti-expansion strip 25 from deforming due to thermal expansion during EPP high-pressure foaming, thereby effectively preventing the insert from deforming due to thermal expansion.
[0054] In this embodiment, the first molding frame 11, the second molding frame 21, the top plate 12, and the bottom plate 22 are all made of 5083 aluminum alloy. 5083 aluminum alloy has advantages such as high thermal conductivity, high thermal stability, lightweight, and strong corrosion resistance. During the EPP foaming process, its high thermal conductivity can shorten the heating or cooling time of the mold, significantly improving production efficiency. The first molding frame 11, the second molding frame 21, the top plate 12, and the bottom plate 22 have low coefficients of thermal expansion, reducing the probability of thermal deformation. The first molding frame 11, the second molding frame 21, the top plate 12, and the bottom plate 22 have strong corrosion resistance to high-temperature steam, residual foaming agent, and condensate, reducing the frequency of mold maintenance. The lightweight design of the upper module 10 and the lower module 20 can reduce the load on the mold and lower energy consumption. In addition, the 5083 aluminum alloy has moderate strength and can withstand the impact of EPP high-pressure foaming expansion.

[0057] Please see Figure 11 and Figure 12 The first insert 111 and the second insert 112 are fixedly connected by bolts, and the third insert 211 and the fourth insert 212 are fixedly connected by bolts.
[0058] More specifically, the first insert 111 has a first connecting hole 1112 extending outward from the first mating groove 113 at both ends, and the second insert 112 has a first screw hole 1122 corresponding to the first connecting hole 1112. The bolt is inserted into the first connecting hole 1112 from the outside of the first insert 111 and screwed into the first screw hole 1122, so as to achieve a more stable splicing of the first insert 111 and the second insert 112, and prevent the precision instability between the first insert 111 and the second insert 112 during the high-pressure foaming expansion of EPP.
[0059] The third insert 211 has a second connecting hole 2112 extending outward from the second mating groove 213 at both ends. The fourth insert 212 has a second screw hole 2122 corresponding to the second connecting hole 2112. The bolt is inserted into the second connecting hole 2112 from the outside of the third insert 211 and screwed into the second screw hole 2122, so as to achieve a more stable splicing of the third insert 211 and the fourth insert 212, and to prevent the precision instability between the third insert 211 and the fourth insert 212 during EPP high-pressure foaming expansion.
