Description

Technical Field

[0001] This invention relates to the field of hot press molding machine technology, specifically a hot press molding machine for the production and processing of small baby cribs. Background Technology

[0002] The curved guardrails, headboards, and other components of small cribs often have complex curved shapes. They are produced using wood panels, bamboo, or plastic composite materials through hot pressing, which is an efficient way to ensure their beautiful appearance and structural consistency. The hot pressing process involves heating and softening the blank, then pressing and cooling it in a mold to obtain the desired three-dimensional shape.

[0003] Currently, existing thermoforming equipment for such small parts still has the following problems: 1. In existing equipment, the movement and positioning of the lower mold between different workstations often rely on multiple independent hydraulic or pneumatic drive units controlled by sensor signals, or a simple manual latch. The former is complex and costly, and the sensors are easily interfered with or fail under high-temperature and dusty conditions, leading to inaccurate positioning signals and unreliable locking actions, which may cause mold closing deviations or even mold collisions. The latter relies entirely on manual operation, which is inefficient and poses safety hazards due to forgetfulness or operational errors. Neither of these methods can reliably guarantee accurate mold alignment in long-term continuous production, directly affecting the consistency of product dimensions.

[0004] 2. In pursuit of structural rigidity, many existing thermoforming machines adopt integral welded or complexly assembled frames, with the lower mold and its drive mechanism deeply hidden inside the equipment. When it is necessary to change the mold to adapt to different products, or to repair the drive mechanism and heating elements, large-scale disassembly work is often required, which is time-consuming and labor-intensive, seriously affecting the flexibility of the production line and the utilization rate of the equipment. This non-modular design increases the downtime and maintenance costs of the equipment.

[0005] 3. Uncertainty in mold positioning may require additional manual verification or adjustment. The complex structure restricts the open feeding area and narrows the operating space. The layout of various functional components (such as ejection, heating, and pressing) lacks optimization of the operation process, resulting in long waiting times between processes. These factors together restrict the further improvement of equipment production cycle and increase the labor intensity of operators.

[0006] Therefore, a thermoforming machine for the production and processing of small baby cribs is needed to improve the above problems. Summary of the Invention

[0007] To address the problems of poor mold positioning reliability, inconvenient equipment maintenance, and reduced production efficiency, this invention provides a hot press molding machine for the production and processing of small baby cribs, thus solving the aforementioned issues.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A thermoforming machine for the production and processing of small baby cribs includes a base box assembly, a push assembly, a work box assembly, a press assembly, a positioning assembly, and a cover plate assembly.

[0009] The base box assembly includes a base box, with horizontal slots on both side plates and a vertical slot on the top of the base box.

[0010] The work box assembly includes a work box, the bottom of which has a groove, vertical inserts fixed on both sides of the work box, a second sliding groove on the inner side of the two side plates of the work box, a linear module installed at the bottom of the work box, a mounting base assembly fixed at the output end of the linear module, a lower mold fixed at the top of the mounting base assembly, and the vertical inserts inserted into the vertical slots.

[0011] The pressing assembly includes a mounting plate, a horizontal insert block fixed to the bottom of the mounting plate, a slider fixed to the top of the mounting plate, a second hydraulic rod mounted on the mounting plate, a fixing plate fixed to the output end of the second hydraulic rod, an upper mold fixed to the bottom surface of the fixing plate, and the horizontal insert block inserted into the horizontal slot.

[0012] The positioning assembly includes a positioning head, a connecting rod, and a spring. One end of the connecting rod is fixed to the positioning head, and the spring is sleeved on the connecting rod. The mounting base assembly has a connecting hole and a connecting groove communicating with the connecting hole. The connecting rod is slidably fitted in the connecting hole, the positioning head is slidably fitted in the connecting groove, and the extended end of the positioning head is slidably fitted in a second sliding groove.

[0013] The pushing assembly includes a push block, which is inserted into a groove and overlaps with a positioning head.

[0014] The cover plate assembly includes a cover plate and six bolts, which are threaded to the cover plate. Two of the bolts are threaded to a first semi-threaded groove on the inner wall of the horizontal slot and a third semi-threaded groove on the horizontal insert block, respectively.

[0015] As a preferred embodiment of the present invention, the mounting base assembly includes a mounting base, and the connecting holes and connecting grooves are symmetrically formed on both sides of the mounting base.

[0016] By symmetrically opening connecting holes and connecting grooves on both sides of the mounting base, the positioning components can be evenly distributed on both sides of the mold, which enhances the balance and stability of the lower mold during movement and avoids offset or vibration caused by unilateral force.

[0017] As a preferred embodiment of the present invention, one end of the spring is connected to the inner wall of the connecting groove, and the other end is connected to the end face of the positioning head.

[0018] One end of the spring is fixed to the inner wall of the groove, and the other end is pressed against the positioning head, so that the positioning head extends in the working state, ensuring that it can reliably cooperate with the second slide groove and the groove.

[0019] As a preferred embodiment of the present invention, the top of the working box is provided with a first sliding groove, the slider is located in the first sliding groove, the top of the working box is provided with a second semi-threaded groove, the end face of the slider is provided with a fourth semi-threaded groove, and the other two bolts are respectively threadedly connected to the second semi-threaded groove and the fourth semi-threaded groove.

[0020] The sliding block and the first sliding groove are fitted together and locked together by bolts with the second and fourth semi-threaded grooves, so that the pressing component can slide flexibly and be reliably fixed on the top of the working box. This facilitates the quick centering and adjustment of the upper mold, and improves the convenience of equipment operation and the efficiency of mold replacement.

[0021] As a preferred embodiment of the present invention, the bottom of the base box is provided with a threaded hole, and the two bolts are respectively threadedly connected to the threaded hole.

[0022] By setting threaded holes at the bottom of the base box and using bolts to achieve a firm connection between the cover plate and the base box, the rigidity and stability of the overall equipment are enhanced, preventing vibration or displacement during high-pressure molding and ensuring the smooth progress of the molding process.

[0023] As a preferred embodiment of the present invention, a heating plate is fixed to the inner wall of the working box.

[0024] A heating plate is fixed to the inner wall of the working chamber, which can uniformly heat the space inside the chamber, so that the blank is fully softened before pressing, thereby improving the plasticity and molding adaptability of the material.

[0025] In a preferred embodiment of the present invention, the groove is connected to the second slide groove, and the diameter of the positioning head is the same as the width of the groove.

[0026] The groove is connected to the second slide, and the diameter of the positioning head is the same as the width of the groove, ensuring that the push block of the push assembly can be accurately inserted and push the positioning head to achieve mechanical linkage.

[0027] As a preferred embodiment of the present invention, the center of the cover plate is recessed inward to form a placement cavity, and the driving part of the linear module is located in the placement cavity.

[0028] The cover plate has an inwardly recessed cavity in the center to accommodate the drive unit of the linear module, making the equipment structure more compact and neat, reducing external protruding parts, facilitating the layout and installation of the equipment in the production line, and also helping to protect and dissipate heat from the drive components.

[0029] As a preferred embodiment of the present invention, the jacking assembly further includes a first hydraulic rod and a bracket, the first hydraulic rod being fixed to the bottom plate of the base box, the bracket being fixed to the output end of the first hydraulic rod, and the push block being fixed to the top of the bracket.

[0030] The jacking assembly uses a first hydraulic rod to drive the bracket and push block, realizing automated jacking and resetting, and pushing the positioning head to complete the switching of the mold positioning state.

[0031] As a preferred embodiment of the present invention, the top of the working box is provided with an opening, and the output end of the second hydraulic rod passes through the opening.

[0032] An opening is made at the top of the work box for the output end of the second hydraulic rod to pass through, making the pressing movement of the upper mold smoother and more accurate in alignment, avoiding bias or wear caused by structural interference.

[0033] Compared with the prior art, the present invention achieves the following beneficial effects by introducing a specific structural design into the thermoforming machine used for the production and processing of small baby cribs: 1. By setting a positioning component driven by a push assembly, the mechanical action of the push block lifting and spring reset is used to control the engagement and disengagement of the positioning head and the slide, thereby reliably locking or releasing the lower mold. The structure is simple, the action is certain, and the lower mold can stably switch between the two key working states of movement and pressing.

[0034] 2. By interlocking vertical blocks with vertical slots and horizontal blocks with horizontal slots, the work box assembly, pressing assembly and base box can be quickly positioned and assembled. Combined with the cover plate assembly and unique semi-threaded groove and bolt locking, multi-point linkage locking is achieved, which simplifies the assembly and disassembly process of the equipment, greatly facilitates mold maintenance, and improves the maintainability and deployment flexibility of the equipment.

[0035] 3. The modular plug-in structure provides reliable mechanical positioning and locking, ensuring that each module is stable after locking, reducing micro-movements caused by vibration or stress, and keeping the mold alignment, heating and pressing processes stable. While achieving modular convenience, it also improves overall production efficiency. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Example: Please refer to Figure 1-15 The hot press molding machine shown is used for the production and processing of small baby cribs. It includes a base box assembly 1, a push assembly 2, a work box assembly 3, a pressing assembly 4, a positioning assembly 5, and a cover plate assembly 6. It is suitable for manufacturing parts with three-dimensional curved surfaces such as curved guardrails and headboards of baby cribs using plastic composite materials as raw materials through hot press molding process.

[0040] Based on the aforementioned structural features and connection relationships, reliable transfer and locking of the lower mold between the open loading position and the closed pressing position can be achieved, and efficient and stable hot pressing molding operation can be completed.

[0041] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the base box assembly 1 includes a base box 101, with support legs 106 fixed at the four corners of the bottom of the base box 101. A horizontal slot 102 is provided on each of the left and right side plates of the base box 101, and a first semi-threaded groove 103 is machined on the inner wall of each horizontal slot 102. A vertical slot 104 is provided on each of the left and right sides of the top of the base box 101, and two threaded holes 105 are also provided in the middle of the bottom plate of the base box 101.

[0042] The jacking assembly 2 includes a first hydraulic rod 201, a bracket 202, and a push block 203. The first hydraulic rod 201 is vertically fixed to the center of the bottom plate of the base box 101 by fasteners. The bracket 202 has an inverted U-shaped structure, and its lower end is fixedly connected to the output flange of the first hydraulic rod 201. The push block 203 is a cuboid block, and its bottom is fixed to the top crossbeam of the bracket 202 by bolts.

[0043] The work box assembly 3 includes a work box 301, with a through rectangular groove 302 at the center of its bottom. A vertical insert 303 is fixed to the lower part of each of the left and right outer walls of the work box 301. A long, narrow first sliding groove 304 is formed on each of the left and right sides of the top of the work box 301. A second semi-threaded groove 305 is machined on the inner wall of each of the first sliding grooves 304. A second sliding groove 306 is vertically formed in the middle of the inner walls of each of the left and right sides of the work box 301, extending downwards to communicate with the groove 302. A linear module 307 is bolted to the bottom surface inside the work box 301. The linear module 307 slides in the front-back direction, and a mounting base assembly 30 is bolted to the slider of the linear module 307. 8. The mounting base assembly 308 includes a rectangular mounting base 3081. The top of the mounting base 3081 is fixed with a lower mold 309 by bolts. On the left and right sides of the mounting base 3081, a circular connecting hole 3082 is symmetrically opened. The inner side of each connecting hole 3082 is connected to a square connecting groove 3083. Multiple heating plates 3012 are fixed around the inner wall of the working box 301 by bolts. A circular through-hole 3010 is opened at the top center of the working box 301 for the second hydraulic rod 406 of the lower pressing assembly 4 to pass through. Through grooves 3011 for cables to pass through are also opened on the left and right side walls of the working box 301. Two vertical inserts 303 at the bottom of the work box 301 are aligned with two vertical slots 104 at the top of the base box 101, and then placed vertically downwards so that the vertical inserts 303 are fully inserted into the vertical slots 104, thereby installing the work box 301 on the base box 101. The linear module 307 is a ball screw linear module. The base of the linear module 307 is fixed to the preset mounting holes on the bottom plate inside the work box 301 by fasteners. A rectangular resistance heating plate 3012 is fixed to the left, right and rear inner walls of the work box 301 by screws. The heating plate 3012 is electrically connected to a temperature controller located outside the equipment.

[0044] In this embodiment, specific references Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the pressing assembly 4 includes a mounting plate 401. A horizontal insert block 402 is fixed to each of the left and right sides of the bottom of the mounting plate 401, and a third semi-threaded groove 403 is machined on the outer surface of each horizontal insert block 402. A slider 404 is fixed to each of the left and right sides of the top of the mounting plate 401, and a fourth semi-threaded groove 405 is machined on the end face of each slider 404. A second hydraulic rod 406 is bolted to the center of the mounting plate 401. The output end of the second hydraulic rod 406 passes downward through the mounting plate 401 and is connected to a rectangular fixing plate 407 via a flange. An upper mold 408 is bolted to the bottom surface of the fixing plate 407.

[0045] The two horizontal inserts 402 at the bottom of the mounting plate 401 are inserted horizontally into the horizontal slots 102 on both sides of the base box 101 from the rear of the work box 301. At the same time, the two sliders 404 at the top of the mounting plate 401 are respectively embedded in the two first sliding grooves 304 at the top of the work box 301, and the pressing component 4 can slide back and forth along the first sliding grooves 304. When the upper mold 408 needs to be aligned with the lower mold 309, the pressing component 4 is slid to the appropriate position, and then two bolts 603 are used. Each bolt passes through the corresponding hole on the cover plate 601 and is screwed into the complete threaded hole formed by the second half-threaded groove 305 on the work box 301 and the fourth half-threaded groove 405 on the slider 404, thereby locking and fixing the pressing component 4 to the top of the work box 301.

[0046] The first semi-threaded groove 103 and the third semi-threaded groove 403 are aligned and together form a complete internal threaded hole when the horizontal insert block 402 is fully inserted into the horizontal slot 102.

[0047] In this embodiment, specific references Figure 11 , Figure 12 and Figure 13 As shown, the positioning component 5 includes a cylindrical positioning head 501, a connecting rod 502, and a spring 503. One end of the connecting rod 502 is welded and fixed to the center of the tail of the positioning head 501. The spring 503 is sleeved on the connecting rod 502. In its natural state, the length of the spring 503 is greater than the depth of the connecting groove 3083, so that it is always under pressure after installation, thereby providing a constant outward elastic force to the positioning head 501.

[0048] On each side of the mounting base 3081, the connecting rod 502 of the positioning assembly 5 is inserted into the connecting hole 3082 from the outside of the mounting base 3081. At the same time, the positioning head 501 slides into the connecting groove 3083. The spring 503 is located in the connecting groove 3083, with one end abutting against the inner side wall of the connecting groove 3083 and the other end abutting against the tail end face of the positioning head 501. Under the elastic force of the spring 503, the positioning head 501 tends to extend outward from the mounting base 3081 (i.e. towards the side wall of the work box 301). When the mounting base 3081 is inside the work box 301, the extended end of the positioning head 501 just slides into the second sliding groove 306 inside the work box 301 and can slide up and down along the second sliding groove 306. The diameter of the front end of the positioning head 501 is the same as the width of the groove 302 at the bottom of the work box 301.

[0049] The top surface of the mounting base 3081 is provided with a standard positioning groove and an array of threaded holes for adapting to the installation of different models of lower molds 309, and the bottom surface of the fixing 407 is provided with a corresponding standard interface for quick installation of the upper mold 408.

[0050] In this embodiment, specific references Figure 3 , Figure 4 , Figure 11 and Figure 12 As shown, the push block 203 of the push assembly 2 is located directly below the groove 302 at the bottom of the work box 301. When the first hydraulic rod 201 pushes the bracket 202 and the push block 203 upward, the push block 203 will insert into the groove 302 and push the two positioning heads 501 upward, so that the positioning heads 501 retract towards the center of the mounting base 3081 against the elastic force of the spring 503, thereby disengaging their front ends from the second slide groove 306. When the first hydraulic rod 201 retracts, it drives the push block 203 to descend and completely exit the groove 302. The pushing force applied to the positioning head 501 disappears, and the elastic force of the spring 503 pushes the positioning head 501 to reset outward, so that its protruding end is reinserted into the second slide groove 306 (if the mounting base 3081 has moved to the corresponding position), or to prepare for the next insertion.

[0051] In this embodiment, specific references Figure 1 , Figure 14 and Figure 15 As shown, the cover plate assembly 6 includes a rectangular cover plate 601 and six bolts 603. The center of the cover plate 601 is punched inward to form a placement cavity 602. Six through holes are machined on the cover plate 601 for the bolts 603 to pass through.

[0052] Cover the back of the work box 301 (i.e., the side with the horizontal insert block 402) with cover plate 601. Two bolts 603 are inserted through the holes on the upper left and right sides of cover plate 601, respectively. Each bolt is screwed into the complete threaded hole formed by the first half-threaded groove 103 on the inner wall of the horizontal slot 102 on the bottom box 101 and the third half-threaded groove 403 on the horizontal insert block 402, thereby locking the horizontal insert block 402 of the pressing assembly 4 onto the bottom box 101. The other two bolts 603 are inserted through the holes in the middle of the left and right sides of cover plate 601, respectively. Each bolt is screwed into the complete threaded hole formed by the first half-threaded groove 103 on the inner wall of the horizontal slot 102 on the bottom box 101 and the third half-threaded groove 403 on the horizontal insert block 402. The first screw is inserted into the complete threaded hole formed by the second half-threaded groove 305 on the working box 301 and the fourth half-threaded groove 405 on the slider 404, thereby locking and fixing the already aligned pressing component 4 to the top of the working box 301. Finally, the two bolts 603 are inserted through the two holes at the bottom of the cover plate 601 and screwed directly into the two pre-made threaded holes 105 at the bottom of the base box 101, thereby firmly connecting the lower end of the cover plate 601 to the base box 101. After assembly, the drive part (motor, etc.) of the linear module 307 is located in the placement cavity 602 of the cover plate 601.

[0053] The working process of the thermoforming machine used in the production and processing of small baby cribs is as follows: The first hydraulic rod 201 is in the retracted state, and the push block 203 is at its lowest point. Under the action of the spring 503, the two positioning heads 501 extend and are locked in the second slide groove 306 at the rear of the work box 301, locking the mounting base 3081 and the lower mold 309 in the rear opening position, so that the operator can place the preheated and softened plate blank on the surface of the lower mold 309.

[0054] The first hydraulic rod 201 is extended, pushing the bracket 202 and push block 203 upward. Push block 203 inserts into the groove 302 of the work box 301 and pushes back the two positioning heads 501, causing their front ends to retract completely and disengage from the second slide groove 306. The longitudinal lock of the lower mold 309 is released. The linear module 307 is activated, driving the mounting base 3081 and the lower mold 309 (along with the blank on it) to move forward along the guide rail to the pressing position inside the work box, directly opposite the upper mold 408.

[0055] After the mounting base 3081 reaches the predetermined pressing position, the first hydraulic rod 201 retracts, causing the push block 203 to descend and completely exit the groove 302. After the push block 203 retracts, the elastic force of the spring 503 immediately pushes the two positioning heads 501 to extend outward, so that their front ends are inserted into the second slide groove 306 section located at the pressing position, thereby locking the lower mold 309 longitudinally at the pressing position.

[0056] The heating plate 3012 on the inner wall of the working box 301 operates to keep the space inside the box and the blank warm or provide supplementary heating. Then, the second hydraulic rod 406 extends downward, driving the fixed plate 407 and the upper mold 408 to move downward and close with the lower mold 309, applying pressure to the blank and holding it under pressure. After holding the pressure for a period of time, heating is stopped, and cooling can be carried out. After cooling and shaping, the second hydraulic rod 406 retracts, driving the upper mold 408 to rise back to its original position. The first hydraulic rod 201 extends again, and the push block 203 rises and inserts into the groove 302, positioning the positioning head 501. The pusher returns the mold 309 to the second slide 306, releasing the lock on the lower mold 309. Then, the linear module 307 moves in the opposite direction, moving the mounting base 3081 and the lower mold 309 with the molded product back to the initial opening position. After the lower mold 309 is in place, the first hydraulic rod 201 retracts, the pusher block 203 descends and exits, and the spring 503 pushes the positioning head 501 to extend and insert into the second slide 306 at the rear, relocking the lower mold 309 in the opening position. The molded product can then be safely removed, and the equipment returns to its initial state, ready for the next cycle.

[0057] The linear module 307, the first hydraulic rod 201, the second hydraulic rod 406, the heating plate 3012, etc. used in this invention are all common standard components or modules in this technical field. Their specific internal structure, circuit principle and selection model are well known to those skilled in the art and are convenient to purchase in the market.
