Description

Technical Field

[0001] This utility model relates to the field of material forming and processing technology, specifically to an EPP material forming device. Background Technology

[0002] In the field of materials processing and manufacturing, EPP material is widely used in various sectors such as the automotive industry, packaging industry, construction industry, and sporting goods manufacturing due to its unique performance advantages, such as low density, high strength, good thermal insulation, strong impact resistance, and recyclability. With the continuous increase in demand for EPP products from various industries, the market demand for efficient and high-quality EPP material molding equipment is also becoming increasingly urgent.

[0003] Traditional EPP material molding methods have revealed numerous problems during the production process. For example, some simple molding dies struggle to guarantee the accuracy of product dimensions and the stability of the shape during molding, resulting in a low product qualification rate and increased production costs. Moreover, in the demolding process, due to unreasonable mold structure design, products often stick to the mold, making demolding difficult. This not only easily damages the product and affects product quality but also reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an EPP material molding device. The lower surface of the mold base has a recessed molding cavity, which provides a basic space for product molding. The arrangement of the drive components and the pushing unit enables the product to be molded in a sealed manner with the mold base during molding, and the product can be smoothly pushed out of the molding cavity after molding.

[0005] The objective of this utility model is achieved through the following solution:

[0006] This utility model discloses an EPP material molding device, comprising:

[0007] The mold base has a molding cavity with an opening at one end recessed on its lower surface;

[0008] A driving assembly is installed on the outer side of the mold base away from the molding cavity. The driving assembly is movably connected to a pushing unit. The pushing unit is movably disposed in the through channel of the mold base, and the projection of the portion of the pushing unit movably disposed in the through channel in the vertical direction coincides with the projection of the through channel in the vertical direction.

[0009] When the EPP material molding device is molding, the pushing unit is sealed with the through channel and cooperates with the mold base to mold the product in the molding cavity; after the product is molded, the pushing unit of the drive assembly pushes the product out of the molding cavity to complete demolding.

[0010] Furthermore, the driving component includes a driving unit, and the pushing unit is mounted on the driving end of the driving unit.

[0011] Furthermore, the driving unit is a driving cylinder, the driving end of the driving cylinder is a driving rod, and the pushing unit is fixedly installed on the driving rod of the driving cylinder.

[0012] Furthermore, the driving unit is a drive motor, the driving end of the drive motor is a helical shaft, and a screw that cooperates with the helical shaft to drive the driving unit to reciprocate linearly is fixedly installed on the pushing unit.

[0013] Furthermore, the EPP material molding apparatus also includes a support assembly, which includes two support columns arranged vertically at intervals on the mold base and a support plate laterally connected to the upper ends of the two support columns. The drive unit is fixedly mounted on the support plate, and the drive end extends through the clearance hole of the support plate toward the mold base.

[0014] Furthermore, the pushing unit includes a mounting bracket fixedly connected to the driving end of the driving unit and a pushing block connected to the mounting bracket, the pushing block being fixed to the mounting bracket by bolts.

[0015] Furthermore, the outer walls on both sides of the mounting bracket are provided with limiting blocks, and the support columns on both sides of the fixed mold base are provided with limiting grooves extending vertically corresponding to the limiting blocks. The limiting blocks are slidably disposed in the limiting grooves so that the pushing unit reciprocates vertically.

[0016] Furthermore, the support plate is equipped with a vertically arranged sliding rod, and the mounting bracket has a sliding hole that cooperates with the sliding rod. The mounting bracket can slide up and down along the sliding rod. When the product is being injected, the lower end of the sliding rod abuts against the upper surface of the push block to limit the push block.

[0017] Furthermore, the push block includes a first push block with a receiving groove and a second push block located within the receiving groove, the first push block and the second push block being connected to the mounting bracket respectively.

[0018] Furthermore, the lower surface of the first pushing block and the lower surface of the mounting bracket are located on the same plane, the second pushing block can extend out of the receiving groove, and the lower end face of the second pushing block is provided with a model structure for molding the product.

[0019] The advantages of this invention are that the pushing unit is accurately positioned within the through-channel and fits tightly with the mold base. During the molding process, it applies uniform and precise pressure to the EPP material, ensuring that the product is accurately molded into the predetermined shape within the molding cavity, effectively reducing dimensional deviations and improving the product yield. After molding, the drive assembly can quickly drive the pushing unit to eject the product from the molding cavity, achieving rapid demolding. This design reduces demolding time, improves production efficiency, and reduces the risk of product damage that may occur with manual demolding. Attached Figure Description

[0027] Please see Figures 1-4 This utility model discloses an EPP material molding device, comprising:

[0028] The mold base 100 has a molding cavity 110 with an opening at one end recessed on its lower surface;

[0029] A drive assembly 200 is mounted on the outer side of the mold base 100 away from the molding cavity 110. The drive assembly 200 is movably connected to a push unit 220. The push unit 220 is movably disposed in the through channel of the mold base 100, and the vertical projection of the part of the push unit 220 movably disposed in the through channel coincides with the vertical projection of the through channel.

[0030] When the EPP material molding device is used for molding, the pushing unit 220 is sealed to the through channel and cooperates with the mold base 100 to mold the product in the molding cavity 110. After the product is molded, the pushing unit 220 of the drive assembly 200 pushes the product out of the molding cavity 110 to complete demolding. The sealing arrangement between the pushing unit 220 and the through channel prevents EPP material from leaking into the through channel during the molding process, ensuring a stable pressure and temperature environment in the molding cavity 110, thereby ensuring high-quality product molding. After the product is molded, the drive assembly 200 drives the pushing unit 220 to move along the through channel into the molding cavity 110, pushing the molded product out of the molding cavity 110 to complete the demolding operation.

[0031] Please see Figure 1 The driving assembly 200 includes a driving unit 210, and a pushing unit 220 is mounted on the driving end of the driving unit 210. Preferably, the driving unit 210 is a driving cylinder, the driving end of the driving cylinder is a driving rod, and the pushing unit 220 is fixedly mounted on the driving rod of the driving cylinder. Preferably, the driving unit 210 is a driving motor, the driving end of the driving motor is a helical shaft, and a screw that cooperates with the helical shaft to drive the pushing unit 220 to perform linear reciprocating motion is fixedly mounted on the pushing unit 220.

[0032] Please see Figure 1The EPP material molding apparatus further includes a support assembly 300. The support assembly 300 includes two support columns 310 vertically spaced on the mold base 100, and a support plate 320 laterally connected to the upper ends of the two support columns 310. The drive unit 210 is fixedly mounted on the support plate 320, and its drive end extends through a clearance hole in the support plate 320 toward the mold base 100. The support columns 310, as the main load-bearing structure of the entire support assembly 300, bear the weight of the upper support plate 320 and the drive unit 210 mounted on the support plate 320, while providing stable support for these components to ensure they do not shake or shift during operation, thus guaranteeing the accuracy and stability of the molding apparatus. The support plate 320 provides a mounting platform for the drive unit 210, allowing the drive unit 210 to be securely fixed to the support assembly 300. Meanwhile, the design of the clearance hole ensures that the driving end of the driving unit 210 can extend towards the mold base 100 so as to connect with components such as the pushing unit 220 to realize molding and demolding operations.

[0033] Please see Figures 1-2 The pushing unit 220 includes a mounting bracket 221 fixedly connected to the driving end of the driving unit 210, and a pushing block 222 connected to the mounting bracket 221. The pushing block 222 is fixed to the mounting bracket 221 by bolts 223. The mounting bracket 221 accurately transmits the driving force generated by the driving unit 210 to the pushing block 222, while providing a stable mounting platform for the pushing block 222, ensuring that the pushing block 222 can maintain the correct position and posture during operation, thereby achieving precise molding and demolding operations. Driven by the driving unit 210, the pushing block 222 cooperates with the molding cavity 110 to apply pressure to the EPP material, molding it into the desired product shape within the molding cavity 110. During the demolding stage, the pushing block 222 pushes the molded EPP product out of the molding cavity 110, completing the demolding operation. During the operation of the EPP material molding device, the driving end of the driving unit 210 generates a driving force, which is transmitted to the pushing block 222 through the mounting bracket 221. Under the action of driving force, the push block 222 moves in a predetermined direction. During the molding operation, the push block 222 moves towards the molding cavity 110, cooperating with the molding cavity 110 to extrude the EPP material, molding it into the product shape within the molding cavity 110. During the demolding operation, the push block 222 moves in the opposite direction, pushing the molded EPP product out of the molding cavity 110, thus achieving demolding.

[0034] Please see Figure 1The pushing block 222 includes a first pushing block 2221 with a receiving groove and a second pushing block 2222 located within the receiving groove. During the operation of the EPP material molding device, the drive unit 210 drives the mounting bracket 221 to reciprocate vertically. The first pushing block 2221 and the second pushing block 2222 are respectively connected to the mounting bracket 221 and move together with the mounting bracket 221. When performing product molding operations, the mounting bracket 221 drives the first pushing block 2221 and the second pushing block 2222 to move downward, applying pressure to the EPP material. The second pushing block 2222 first contacts the EPP material to perform preliminary molding of the product; subsequently, the second pushing block 2222 further acts within the receiving groove of the first pushing block 2221 to precisely mold specific parts of the product. Through the coordinated work of the first pushing block 2221 and the second pushing block 2222, comprehensive and precise molding of the EPP material is achieved, ensuring the dimensional accuracy and quality stability of the product. The lower surface of the first pushing block 2221 is on the same plane as the lower surface of the mounting bracket 221. The second pushing block 2222 extends out of the receiving groove, and the lower end face of the second pushing block 2222 is provided with a model structure for molding the product. During the operation of the EPP material molding device, the drive unit 210 drives the mounting bracket 221 to reciprocate vertically. Since the lower surface of the first pushing block 2221 and the lower surface of the mounting bracket 221 are on the same plane, they move downward synchronously, applying initial pressure to the EPP material. The second pushing block 2222 extends out of the receiving groove of the first pushing block 2221. The model structure on the lower end face of the second pushing block 2222 contacts the EPP material, further applying pressure to achieve precise molding of specific parts of the product. After molding is completed, the second pushing block 2222 retracts into the receiving groove, and the mounting bracket 221 drives the first pushing block 2221 and the second pushing block 2222 to move upward, completing one molding cycle.

[0035] Please see Figure 3The mounting bracket 221 has protruding limiting blocks 2211 on both outer walls. The support columns 310 on both sides of the mold base 100 have recessed limiting grooves 311 extending vertically, corresponding to the limiting blocks 2211. The limiting blocks 2211 are slidably disposed within the limiting grooves 311 to allow the pushing unit 220 to reciprocate vertically. During the operation of the EPP material molding device, the drive unit 210 drives the pushing unit 220 to reciprocate vertically. When the drive end of the drive unit 210 extends or retracts, the mounting bracket 221 moves accordingly, and the limiting blocks 2211 on both sides slide within the limiting grooves 311 on the support columns 310. The limiting grooves 311 guide and limit the limiting blocks 2211, ensuring that the pushing unit 220 can only move vertically, preventing it from shifting or wobbling in the horizontal direction. This limiting structure ensures precise matching between the pushing unit 220 and the molding cavity 110, enabling the pushing block 222 to accurately enter and exit the molding cavity 110, thereby realizing the molding and demolding operations of EPP material and improving the molding accuracy and quality of the product.

[0036] Please see Figure 3 The support plate 320 is equipped with a vertically arranged sliding rod 321. The mounting bracket 221 has a sliding hole 2212 that mates with the sliding rod 321. The mounting bracket 221 can slide up and down along the sliding rod 321. When the product is being injected, the lower end of the sliding rod 321 abuts against the upper surface of the push block 222 to limit the push block 222. During normal operation of the EPP material molding device, the drive unit 210 drives the mounting bracket 221 to reciprocate vertically, thereby moving the push block 222. When the product is being injected, the mounting bracket 221 moves the push block 222 downward, applying pressure to the EPP material. At this time, the sliding rod 321 moves downward along with the mounting bracket 221, and its lower end gradually abuts against the upper surface of the push block 222. The sliding rod 321 provides a vertical limit for the push block 222, preventing the push block 222 from being excessively pressed down under the injection pressure, thus ensuring the dimensional accuracy and quality stability of the molded product. Meanwhile, the sliding rod 321 cooperates with the sliding hole 2212 on the mounting bracket 221 to provide guidance for the movement of the pushing unit 220, ensuring that the pushing unit 220 always moves in the vertical direction and avoiding horizontal deviation and swaying.

[0037] The EPP material molding device provided by this utility model features a pusher unit 220 that moves accurately within the through channel and fits tightly with the mold base 100. During the molding process, it applies uniform and precise pressure to the EPP material, ensuring that the product is precisely molded into a predetermined shape within the molding cavity 110, effectively reducing product dimensional deviations and improving product yield. After molding is complete, the drive assembly 200 can quickly drive the pusher unit 220 to eject the product from the molding cavity 110, achieving rapid demolding. This design reduces demolding time, improves production efficiency, and reduces the risk of product damage that may occur with manual demolding.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
