Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of hot pressing of wood veneer, and relates to a hot pressing wood veneer placement fixture. Background Technology
[0002] Real wood decorative parts are products made from wood veneer materials through processes such as composite processing, hot pressing, injection molding, milling, and spraying. Among these processes, hot pressing is one of the key steps in forming real wood decorative parts, determining the final quality of the finished product. During hot pressing, the wood veneer material to be processed is placed in a hot pressing mold. The high temperature of the mold softens the veneer, and pressure is applied to the veneer to fix it into shape.
[0003] Existing wood veneer hot pressing molds typically integrate the forming fixture and the mold into a single unit. After the wood veneer is hot-pressed onto the forming surface of the fixture, workers need to manually remove it from the fixture, or use pry bars or jacks to detach it. Due to the high-temperature environment of hot pressing, workers are prone to burns during the removal of the wood veneer, and the process of prying off the edges can easily damage the veneer.
[0004] Therefore, in view of the above-mentioned problems of existing wood veneer hot pressing fixtures, this utility model discloses a hot pressing wood veneer placement fixture. Utility Model Content
[0005] The purpose of this utility model is to provide a hot-pressed veneer placement fixture, which facilitates workers to safely and efficiently remove veneers, avoids burns to workers, and improves the efficiency of veneer removal.
[0006] This utility model is achieved through the following technical solution:
[0007] A hot-pressed veneer placement fixture includes a hot-pressing mold, a hot-pressing cavity inside the hot-pressing mold, a hot-pressing punch inside the hot-pressing cavity, and a hot-pressing forming surface on the top of the hot-pressing punch. A veneer fixture is arranged around the edge of the hot-pressing punch, and a plurality of veneer positioning elements in contact with the veneer are arranged on the top of the veneer fixture. At least one handle extending to the outside of the hot-pressing mold is provided on one side of the veneer fixture.
[0008] The wood veneer material is laid on the hot press die, with the bottom of the veneer material in contact with the veneer positioning piece. After the wood veneer material is hot-pressed, the operator can move the veneer fixture upwards using a handle, thereby ejecting the formed wood veneer from the hot press die for demolding. Then, the veneer fixture and the formed wood veneer are moved outside the hot press chamber to prevent workers from being burned during demolding and to avoid damaging the formed wood veneer.
[0009] To better realize this utility model, the wood veneer positioning component further includes an elastic positioning pin, the hot pressing punch is provided with clearance grooves on the left and right sides, the wood veneer fixture is provided with support rods extending into the clearance grooves on the left and right sides, and the top of the support rod is provided with an elastic positioning pin.
[0010] To better realize this utility model, further, an offset groove is provided on one side of the avoidance groove, and an offset pad is provided inside the offset groove.
[0011] To better realize this utility model, the top end of the elastic positioning pin is further positioned above the clearance groove.
[0012] To better realize this utility model, further, a plurality of guide blocks are provided at the edge of the hot pressing cavity, the top of the guide block is provided with an inclined guide surface, and the bottom of the guide block is provided with a positioning surface that contacts the edge of the wood veneer fixture on the side close to the wood veneer fixture.
[0013] To better realize this utility model, the tilt angle of the guide surface is further 30-45°.
[0014] To better realize this utility model, further, two connecting rods are arranged side by side on one side of the wood veneer fixture, a slot is provided on one side of the hot pressing mold for the connecting rods to pass through, and a handle is provided at the end of the connecting rods extending to the outside of the hot pressing cavity.
[0015] To better realize this utility model, the handle is made of wood, and the hot pressing punch is made of 45# steel.
[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0017] This invention separates the hot-pressing mold and the veneer fixture. The veneer fixture supports the veneer, and after the veneer is hot-pressed, a handle on one side of the veneer fixture drives a veneer positioning component to lift the veneer upwards for demolding. Then, the veneer positioning component and the veneer are moved together outside the hot-pressing area, ensuring that the loading and unloading of the veneer are completed outside the hot-pressing area. This effectively avoids burns to workers and also prevents the veneer from being pried open for demolding, thus preventing damage to the veneer edges. Attached Figure Description

[0026] Example 1:
[0027] This embodiment provides a hot-pressed veneer placement fixture, such as... Figures 1-3As shown, the device includes a hot press mold 1, which has a hot press cavity inside. A hot press punch 2 is provided inside the hot press cavity, and a hot press forming surface is provided on the top of the hot press punch 2. A veneer fixture 3 is provided around the edge of the hot press punch 2. A plurality of veneer positioning parts 4 that contact the veneer are provided on the top of the veneer fixture 3. At least one handle 5 extending to the outside of the hot press mold 1 is provided on one side of the veneer fixture 3.
[0028] The wood veneer material is laid on the hot-pressing forming surface at the top of the hot-pressing punch 2. At this time, the bottom of the wood veneer material is in contact with the top of the wood veneer positioning piece 4 for positioning. The wood veneer material is hot-pressed and formed by the hot press machine in conjunction with the hot-pressing punch 2. After the wood veneer is formed, the operator holds the handle 5 to move the wood veneer fixture 3 upward, and then the wood veneer positioning piece 4 at the top of the wood veneer fixture 3 lifts the formed wood veneer upward, so that the wood veneer is completely demolded from the hot-pressing punch 2. Then, the wood veneer fixture 3 can be moved to the outside of the hot-pressing cavity by the handle 5, and the wood veneer can be removed from the top of the wood veneer positioning piece 4. Then, the unprocessed wood veneer material is placed on the top of the wood veneer positioning piece 4, and then the wood veneer fixture 3 is placed back into the hot-pressing cavity for the next wood veneer hot-pressing forming operation.
[0029] By incorporating the handle 5 and the veneer fixture 3, it is ensured that workers will not come into contact with high-temperature areas during the placement and removal of veneer, effectively preventing burns. Simultaneously, the upward movement of the veneer fixture 3, along with the veneer positioning component 4, demolds the veneer, avoiding damage caused by traditional prying methods.
[0030] Example 2:
[0031] A hot-pressed veneer placement fixture, an improvement on Example 1, such as... Figure 2 and Figure 3 As shown, the veneer positioning component 4 includes an elastic positioning pin 41. The hot-pressing punch 2 has clearance grooves 6 on both sides. The veneer fixture 3 has support rods extending into the clearance grooves 6 on both sides, with the elastic positioning pin 41 positioned at the top of each support rod. By extending the support rods into the clearance grooves 6, the contact point between the elastic positioning pin 41 at the top of the support rod and the bottom of the veneer is kept away from the edge of the veneer, thus preventing damage to the veneer edge.
[0032] Furthermore, an offset groove 7 is provided on one side of the clearance groove 6, and an offset pad 8 is provided inside the offset groove 7. The offset pad 8 limits the elastic positioning pin 41 to ensure that the elastic positioning pin 41 will not tilt or deviate to the side when it is pressed down.
[0033] Furthermore, the top of the elastic positioning pin 41 is positioned higher than the clearance groove 6 to ensure that the elastic positioning pin 41 can contact the bottom of the wood veneer during the hot pressing process.
[0034] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.
[0035] Example 3:
[0036] A hot-pressed veneer placement fixture, improved based on Example 1 or 2, such as... Figures 2-3 As shown, several guide blocks 42 are provided at the edge of the hot pressing cavity. The top of each guide block 42 has an inclined guide surface, and the bottom of each guide block, near the veneer fixture 3, has a positioning surface that contacts the edge of the veneer fixture 3. During the placement of the veneer fixture 3 at the edge of the hot pressing punch 2, the guide surface guides the veneer fixture 3, allowing it to be quickly placed in position. At this time, the edge of the veneer fixture 3 contacts the positioning surface, which then tightens and positions the veneer fixture 3, ensuring it does not move after installation.
[0037] Furthermore, the tilt angle of the guide surface is 30-45°, preferably 30°.
[0038] The other parts of this embodiment are the same as those in Embodiment 1 or 2, so they will not be described again.
[0039] Example 4:
[0040] A hot-pressed veneer placement fixture, improved based on any one of Examples 1-3, such as... Figure 3 As shown, two connecting rods 31 are arranged side by side on one side of the wood veneer fixture 3. A slot for the connecting rods 31 to pass through is provided on one side of the hot pressing mold 1. A handle 5 is provided at the end of the connecting rod 31 extending outside the hot pressing chamber. A connecting hole is provided at the end of the connecting rod 31 extending outside the hot pressing chamber. The handle 5 is connected to the connecting hole on the connecting rod 31 via a connecting bolt. By holding the handle 5, the wood veneer fixture 3 can be easily moved.
[0041] Furthermore, the handle 5 is a wooden handle, which can insulate against heat and prevent workers from getting burned.
[0042] Furthermore, the hot pressing punch 2 is made of 45# steel to ensure that the hot pressing punch 2 has sufficient rigidity to support the wood veneer.
[0043] The other parts of this embodiment are the same as any one of embodiments 1-3, so they will not be described again.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way.
