Description

Technical Field

[0001] This utility model relates to the field of pearl cotton technology, and in particular to a pearl cotton processing and molding device. Background Technology

[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also exhibits excellent chemical resistance, making it an ideal substitute for traditional packaging materials.

[0003] There are currently many processing and molding methods for pearl cotton, one of which is high-temperature hot pressing using molds. This involves first carving or casting a female mold and a male mold using aluminum alloy according to the 3D shape of the product. EPE foam granules are then filled into the female mold. After closing the mold, high-temperature steam is introduced. The granules are heated, melted, bonded, and expanded within the sealed mold cavity, filling all the spaces within the mold. After cooling, the mold is opened and the granules are removed.

[0004] However, in practical applications, it has been found that because the EPE foam is tightly packed and adhered to the mold sidewall after cooling and molding, it needs to be removed from the outside of the EPE foam in its natural state. This not only results in low overall removal efficiency, but may even cause damage to the EPE foam. Therefore, an EPE foam processing and molding device is proposed. Utility Model Content

[0005] Therefore, it is necessary to provide a pearl cotton processing and forming device to address the above-mentioned technical problems. An ejection unit is set in the mold so that after the mold is unfolded, the formed pearl cotton can be ejected outward through the ejection unit, which not only facilitates the subsequent removal operation, but also avoids damage to the pearl cotton.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A pearl cotton processing and forming device includes a lower forming mold and support plates fixed on both sides of the lower forming mold. A top plate is fixed on the top of the support plates, and an upper forming mold is provided below the top plate. The upper forming mold is connected to the top plate through a hydraulic telescopic rod. The top of the lower forming mold has a forming groove, and an ejector plate is provided at the bottom of the forming groove. An ejector column is connected to the bottom of the ejector plate, and one end of the ejector column passes through the bottom of the lower forming mold and is connected to an external ejector unit.

[0008] The ejection unit includes a first support frame connected to the bottom of the ejection column. The surface of the first support frame is provided with a linkage component. A second support frame is fixed on the outer side of the lower forming mold at a position corresponding to the first support frame. The surface of the second support frame is provided with an unlocking component.

[0009] Furthermore, the linkage includes a guide portion located in the middle of the first support frame, a sliding plate slidably disposed within the guide portion, and a linkage plate hinged to the bottom of one end of the sliding plate.

[0010] Furthermore, a transmission plate is fixed to the outer side of the upper forming mold, and the transmission plate and the linkage plate are arranged correspondingly in the height direction.

[0011] Furthermore, a spring is fitted onto the surface of the sliding plate, with one end of the spring fixed to the surface of the sliding plate and the other end fixed to the side wall of the guide portion.

[0012] Furthermore, a sloping contact platform is formed on one side of the top of the sliding plate, and the sloping contact platform is correspondingly arranged with the unlocking component.

[0013] Furthermore, the unlocking component includes a connecting plate fixed to the bottom end of the second support frame, an unlocking rod fixed to the bottom of the connecting plate, the bottom end of the unlocking rod having a chamfered arc surface, and the unlocking rod being arranged in the height direction corresponding to the inclined contact platform.

[0014] Furthermore, a U-shaped stabilizer is slidably provided on the top of the first support frame, and a groove is provided at one end of the U-shaped stabilizer. The U-shaped stabilizer is slidably sleeved on the outside of the second support frame through the groove.

[0015] Furthermore, guide balls are movably embedded at the bottom of the linkage plate.

[0016] Furthermore, guide telescopic rods connected to the upper forming mold are provided at the four corners of the bottom of the top plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The pearl cotton processing and molding device provided by this utility model, through the setting of the ejection unit, can make the transmission plate on the upper molding mold that moves upward after the pearl cotton molding is completed come into contact with the linkage plate. In this way, the linkage plate will move upward synchronously with the upper molding mold, so that the first support frame and the ejection column on it move upward, thereby achieving the effect of the ejection plate ejecting the pearl cotton board, which makes it easier to take it out after molding.

[0019] Since the linkage plate is hinged to the sliding plate, the transmission plate will not obstruct the movement of the upper forming mold when it moves down, thus not affecting the mold closing and forming operation. Attached Figure Description

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] Example 1

[0037] Please refer to Figures 1-8 As shown, a pearl cotton processing and molding device includes a lower molding mold 1 and support plates 11 fixed on both sides of the lower molding mold 1. A top plate 12 is fixed on the top of the support plate 11, and an upper molding mold 2 is provided below the top plate 12. The upper molding mold 2 is connected to the top plate 12 through a hydraulic telescopic rod 21. Activating the hydraulic telescopic rod 21 can close or open the upper molding mold 2 and the lower molding mold 1 to meet the requirements for compression molding and shedding of pearl cotton. The top of the lower molding mold 1 has a molding groove 13, and an ejector plate 14 is provided at the bottom of the molding groove 13. An ejector column 15 is connected to the bottom of the ejector plate 14. The bottom of the molding groove 13 has a groove to accommodate the ejector plate 14. Thus, when the ejector plate 14 is located inside the molding groove 13, the bottom wall of the molding groove 13 is flat and will not affect the molding of pearl cotton. One end of the ejector column 15 passes through the bottom of the lower molding mold 1 and is connected to an external ejector unit 3.

[0038] The ejection unit 3 includes a first support frame 31 connected to the bottom of the ejection column 15. The surface of the first support frame 31 is provided with a linkage member 32. The outer side of the lower forming mold 1 is fixed with a second support frame 33 at the position corresponding to the first support frame 31. The surface of the second support frame 33 is provided with an unlocking member 34.

[0039] Example 2

[0040] The pearl cotton processing and forming apparatus provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4 As shown, the linkage 32 includes a guide portion 320 disposed in the middle of the first support frame 31. A sliding plate 321 is slidably disposed within the guide portion 320, and the sliding plate 321 can slide within the guide portion 320. A linkage plate 322 is hinged to the bottom of one end of the sliding plate 321. Figure 7 As shown, the left end of the linkage plate 322 can only be rotated counterclockwise along the hinge and cannot be rotated clockwise.

[0041] A transmission plate 22 is fixed to the outside of the upper forming mold 2, and the transmission plate 22 and the linkage plate 322 are arranged correspondingly in the height direction.

[0042] A spring 323 is fitted onto the surface of the sliding plate 321. One end of the spring 323 is fixed to the surface of the sliding plate 321, and the other end is fixed to the side wall of the guide portion 320. Under the supporting force of the spring 323 in its natural state, the sliding plate 321 drives the linkage plate 322 to form a shape as shown in the figure. Figure 7 The state shown;

[0043] A sloping contact platform 324 is formed on one side of the top of the sliding plate 321, and the sloping contact platform 324 is correspondingly provided with the unlocking member 34;

[0044] The unlocking component 34 includes a connecting plate 340 fixed to the top of the second support frame 33. An unlocking rod 341 is fixed to the bottom of the connecting plate 340. The bottom end of the unlocking rod 341 has a chamfered arc surface 342. The unlocking rod 341 is positioned in the height direction corresponding to the inclined contact platform 324, thus... Figure 7 As shown, when the transmission plate 22 moves upward against the surface of the linkage plate 322, the upward-moving linkage plate 322 will synchronously drive the inclined contact platform 324 to move upward, so that it forms a sliding contact with the unlocking rod 341. The sliding plate 321, which is subjected to the contact force, will slide to the right, so that the linkage plate 322 is disengaged from the bottom of the corresponding transmission plate 22.

[0045] Specifically, such as Figure 1 As shown, the pearl cotton raw material is placed inside the lower forming mold 1. Then, the hydraulic telescopic rod 21 is activated to move the upper forming mold 2 toward the lower forming mold 1, eventually closing the two molds and forming the extrusion molding of the pearl cotton material (after the mold is closed, high-temperature steam is introduced. The particles are heated, melted, bonded, and expanded in the sealed mold cavity, filling all the space of the mold. This is a conventional technical method and will not be described in detail in this embodiment). After molding, the hydraulic telescopic rod 21 is activated to reset the upper forming mold 2.

[0046] During the resetting process, the transmission plate 22 on the upper forming mold 2 will abut against the lower part of the linkage plate 322. At this time, the linkage plate 322 will drive the sliding plate 321 and the first support frame 31 on it to move upward, and finally the ejector column 15 on the first support frame 31 and the ejector plate 14 on it will be ejected in the forming groove 13, so that the formed pearl cotton material will automatically fall off without manual removal, which is beneficial to better forming protection of pearl cotton.

[0047] When the upper forming mold 2 continues to move upward, the inclined contact platform 324 on the sliding plate 321 will contact the end of the unlocking rod 341 and generate sliding contact. The sliding plate 321, which is subjected to contact, will slide and cause the linkage plate 322 to disengage from the surface of the transmission plate 22, so that the transmission plate 22 is located above the linkage plate 322 without affecting the subsequent mold closing operation.

[0048] At this time, the ejector plate 14, which is under the action of gravity, will fall back into the forming groove 13 and reset, and the sliding plate 321, which is under the action of spring 323, will also reset.

[0049] Example 3

[0050] The pearl cotton processing and molding apparatus provided in Embodiment 1 or 2 can be further optimized, such as... Figure 4 As shown, a U-shaped stabilizer 310 is slidably provided on the top of the first support frame 31. A groove 311 is provided at one end of the U-shaped stabilizer 310. The U-shaped stabilizer 310 is slidably sleeved on the outside of the second support frame 33 through the groove 311. In this way, when the first support frame 31 slides, it can form a guiding effect along the surface of the second support frame 33, which is conducive to maintaining the stability of the first support frame 31 in the sliding state.

[0051] The bottom of the linkage plate 322 is movably embedded with guide balls 325. By setting the guide balls 325, the top of the transmission plate 22 and the linkage plate 322 can form a sliding fit state, which is more conducive to promoting the separation of the linkage plate 322 from the transmission plate 22 when sliding.

[0052] The top plate 12 is provided with guide telescopic rods at the four corners of its bottom, which are connected to the upper forming mold 2.
