Description

Technical Field

[0001] This utility model relates to the field of wood-plastic mold technology, and in particular to a wood-plastic mold frame structure with composite reinforcing ribs. Background Technology

[0002] Wood-plastic molds, as the name suggests, are molds used to produce wood-plastic products. They are a type of plastic mold, particularly suitable for wood-plastic extrusion processes. Wood-plastic composites (WPC), also known as wood-plastic composite materials, are composite materials made by mixing polymer resins and wood fiber materials (such as sawdust, bamboo powder, rice husks, straw, etc.) in a certain proportion, adding special additives, and then processing them through high-temperature extrusion and molding. This material not only has the appearance and texture of wood but also possesses the water resistance and corrosion resistance of plastics, thus it is widely used in construction, outdoor facilities, furniture manufacturing, and many other fields.

[0003] In the extrusion molding process, the wood-plastic mold is bolted to the output end of the extrusion tube. However, this installation method has a significant problem: the weight of the wood-plastic mold is concentrated at the connection point with the extrusion tube, resulting in poor connection strength. After prolonged use, the connection is prone to loosening or damage, affecting the stability of the mold and the quality of the extruded products. Furthermore, because the wood-plastic mold needs to withstand the high temperature and high pressure environment during extrusion, the strength problem at the connection point becomes even more prominent, becoming one of the key factors restricting the production efficiency and quality of wood-plastic products. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a wood-plastic mold frame structure with composite reinforcing ribs to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a wood-plastic mold frame structure with composite reinforcing ribs, including a machine base. An extrusion tube is fixedly installed on the top surface of the machine base. A mold body is fixedly installed at the output end of the extrusion tube by bolts. The axis of the extrusion tube coincides with that of the mold body. The mold body is parallel to the machine base. Two symmetrically arranged assembly frames are slidably connected to the outer surface of the mold body. The two assembly frames are connected by bolts. Two symmetrically arranged first reinforcing ribs are fixedly connected to the bottom of each assembly frame. A second reinforcing rib is fixedly connected between the two first reinforcing ribs. A mounting plate is fixedly connected to the bottom of the two first reinforcing ribs and the second reinforcing rib. An adjustment groove is provided on the top surface of the machine base. A bearing plate is slidably connected to the inner wall of the adjustment groove. Both mounting plates are fixedly connected to the bearing plate by bolts. Two symmetrically arranged grooves are provided on the top surface of the machine base. The adjustment groove is located inside the groove. A locking bolt is rotatably connected to the inner wall of each groove. The threaded part of both locking bolts is threadedly connected to the bearing plate.

[0007] Preferably, in any of the above solutions, the inner wall of each groove is provided with a plurality of linearly arrayed rotating holes, and the screw portion of the locking bolt is rotatably connected to the machine tool through the rotating holes.

[0008] Preferably, in any of the above embodiments, the inner wall of the adjusting groove is fixedly connected with a plurality of symmetrically arranged guide rods, and the bearing plate is slidably connected to the guide rods.

[0009] Preferably, the first reinforcing rib is made of stainless steel, and the second reinforcing rib is made of aluminum alloy.

[0010] Preferably, one side of the second reinforcing rib is provided with a plurality of slots, and one side of the second reinforcing rib is provided with a linear array of the plurality of slots.

[0011] Preferably, in any of the above embodiments, the output end of the extrusion tube and the input end of the mold body are both fixedly connected to a connecting flange, and the two connecting flanges are connected by bolts.

[0012] Preferably, in any of the above solutions, a number of symmetrically arranged positioning pins are fixedly connected to the inner wall of each assembly frame, and positioning holes are provided on both the front and back of the mold body, and the positioning pins are slidably connected to the mold body through the positioning holes.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. This mold frame adopts a detachable assembly frame design. After precise positioning via locating pins and locating holes in the mold body, the assembly frame can be quickly separated from the mold body simply by removing the connecting bolts. A first reinforcing rib made of stainless steel provides ultra-high strength support, while a second reinforcing rib made of aluminum alloy further reduces weight through a slotted design. The combined composite reinforcing rib system reduces the overall structural weight while increasing bending stiffness. This modular design not only facilitates the individual replacement and recycling of the assembly frame, but its dissimilar metal composite structure also effectively suppresses resonance, making it particularly suitable for high-frequency vibration extrusion conditions.

[0015] 2. When adjusting the mold height, first loosen the locking bolts to disengage them from the threaded connection of the support plate. The support plate can then slide smoothly along the guide rod. By screwing the locking bolts into the rotating holes at different heights, the lifting position of the support plate can be precisely controlled. After adjustment, tighten the bolts again to secure it. The deep cavity design of the grooves protects the adjustment mechanism from dust intrusion. This mechanical adjustment scheme achieves precise positioning of the mold body without requiring a hydraulic / electric system, making it particularly suitable for high-temperature and high-humidity plastic extrusion environments. Meanwhile, the stainless steel guide rods ensure no wear or deformation over long-term use. Attached Figure Description

The combined composite reinforcing rib system reduces the overall structural weight while increasing bending stiffness. This modular design not only facilitates the individual replacement and recycling of the assembly frame 4, but its dissimilar metal composite structure also effectively suppresses resonance, making it particularly suitable for high-frequency vibration extrusion conditions. When adjusting the mold height, first loosen the locking bolts 11 to disengage them from the threaded connection of the support plate 9, allowing the support plate 9 to slide smoothly along the guide rod 13. By screwing the locking bolts 11 into the rotating holes 12 at different heights, the lifting position of the support plate 9 can be precisely controlled. After adjustment, the bolts are tightened again for fixation. The deep cavity design of the groove 10 provides protection for the adjustment mechanism, preventing dust intrusion. This mechanical adjustment scheme achieves precise positioning of the mold body 3 without the need for a hydraulic / electric system, making it particularly suitable for high-temperature and high-humidity plastic extrusion environments. Meanwhile, the stainless steel guide rod 13 ensures that there is no wear or deformation during long-term use.
