Description

Technical Field

[0001] The present invention relates to the technical field of compression molding machines, in particular to an automatic compression molding device. Background Art

[0002] Most of the existing workshop presses are manual. Workers place the raw materials on the mold, flatten the raw materials on the mold, and then manually roll the four sides flat with a roller. Finally, they check whether the thickness of the four sides and the bottom plate is consistent. After all the checks are completed, the material is cooled.

[0003] Current die-casting technology relies heavily on manual pressing to produce finished products. This process is highly dependent on worker proficiency, resulting in low efficiency and inherent risks. Consequently, 24 / 7 automated manufacturing is not feasible. Furthermore, manual control of varying product widths and thicknesses is required, leading to a lack of accuracy in product preparation precision control, which contributes to the low yield rate associated with manual die-casting.

[0004] Existing automatic die-stamping technology relies primarily on mold precision, and most processes involve one-shot molding. While this avoids most of the issues associated with manual die-stamping, such as accuracy and product production efficiency, the one-shot process requires uniformity in the flow of raw materials into the mold, requiring accurate material feeding. Furthermore, for products with side edges, insufficient compression can lead to poor side molding quality. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The present invention provides a method for automatic compression molding of a square box-type product, wherein the main raw material of the square box-type product is a thermosetting plastic, a thermoplastic plastic or a rubber material. The specific steps of the method include:

[0039] Step 1: Place the raw material on the forming mold, and squeeze it into contact with the forming mold through the mold press, thereby forming a lunch box product that is initially pressed;

[0040] Step 2: Rollers are placed around the forming mold, parallel to the sides of the forming mold. One set of two parallel rollers A is positioned higher than the other set of two parallel rollers B. The diameter and length of roller A are both smaller than the diameter of roller B. The target extrusion distance between rollers A and B and the forming mold is adjusted, that is, the side forming thickness of the square box product.

[0041] Step 3: Roller A first squeezes and contacts the corresponding side of the press platform under the vertical linear drive, and then roller B contacts the corresponding two side edges of the press platform under the drive of the vertical linear drive component to achieve the initial squeezing of the sides of the formed square box product, and then returns to the initial position;

[0042] Step 4: Adjust the target extrusion distance between rollers A, B and the forming die again. The adjusted distance is the target extrusion distance in step 2 minus the side thickness of the press table.

[0043] Lift the press plate to separate it from the forming mold. Then, roller A first squeezes and contacts the corresponding side of the square box product under the vertical linear drive, and squeezes the side of the square box product. Then, roller B contacts the corresponding two side edges of the square box product under the drive of the vertical linear drive component, achieving the final extrusion of the side edges of the formed square box product.

[0044] In step 4, the distance adjustment between rollers A and B further includes: roller A first contacts the upper surface edge of the side edge corresponding to the square box product (i.e., the connection between the side edge and the bottom surface of the square box product) under the linear drive in the vertical direction, and then adjusts the lateral position of roller A through the adjustment mechanism so that roller A is adjusted to the adjusted distance equal to the target extrusion distance in step 2 minus the side thickness of the press table, thereby completing the extrusion molding action of roller A adaptively adapting to the side edge of the square box product;

[0045] That is, the squeezing of the side edges by rollers A and B couples the vertical force of the linear drive and the lateral force of the adjustment mechanism;

[0046] The same is true for roller B, so as to complete the extrusion molding of the side edge of the square box product. The above method completes the automated molding process for the square box product.

[0047] In order to realize the above-mentioned method of automatic compression molding of square box products, as Figure 1 Paper Figure 5As shown, the present invention provides an automatic die-forming device, comprising a forming die 1 and a press table 2 capable of cooperating with the forming die 1 to extrude and form a raw material on the forming die 1, and of course also comprising a frame 6 for mounting the forming die 1 and the press table 2, wherein the four corners of the press table 2 are connected to the top of the frame 6 via four spring air pumps 9, the function of the spring air pumps being used for stamping and buffering the press table 2, and the forming die 1 is provided with the following around it (that is, connected to the frame 6 around the forming die 1):

[0048] The roller body 3 is parallel to the side of the forming mold 1;

[0049] The linear drive assembly 4 is connected to the roller body 3 and is used to drive the roller body 3 to contact the side surface of the pressing table 2 in the vertical direction from above the forming mold 1 when pressing the product formed by the forming mold 1;

[0050] An adjusting mechanism 5 connected to the roller body 3 and used to adjust the distance between the roller body 3 and the side of the forming mold 1;

[0051] Among them, the linear drive component 4 drives the roller body 3 to complete the contact and extrusion of the side of the press table 2 and then return to the initial position. The press table 2 separates from the forming mold 1, and the adjustment mechanism 5 adjusts the roller body 3 to a position where it can squeeze the press table 2 and press the side surface of the product formed by the forming mold 1 under the drive of the linear drive component 4.

[0052] The specific working principle and method of the automatic compression molding equipment provided by the present invention have been described in the above method.

[0053] A group of two parallel roller bodies 3 located around the forming mold 1 has a length greater than the side length of the forming mold 1 .

[0054] Of course, in the actual molding process, the four roller bodies 3 located in the forming mold 1 can be set at the same height and the same length, that is, the length of the roller body 3 is exactly equal to the length of the forming mold, or the length of the square box product after being formed by the forming mold 1.

[0055] Although the four roller bodies 3 can be set at the same height in an ideal state, the ends of two adjacent roller bodies 3 are in a critical state for the corners of the square box product, and the present invention needs to adjust the distance between the roller body 3 and the forming mold 1, so the side thickness of the square box product and the side thickness of the press table will form a distance difference, and it is obviously impossible to perfectly match after adjustment.

[0056] To this end, in the present invention, the length of another group of two parallel roller bodies 3 located around the forming mold 1 is equal to the side length of the forming mold 1.

[0057] There is a diameter difference greater than zero between two adjacent roller bodies 3; and there is a height difference greater than zero between two adjacent roller bodies 3, and the height difference is smaller than the side width of the product. The purpose is to avoid mutual extrusion and interference between the two groups of roller bodies 3 and to eliminate the above-mentioned critical state.

[0058] Specifically, in order to more clearly illustrate the linear movement process of the roller body 3 driven by the linear drive assembly 4, the present invention provides a specific embodiment of the linear drive assembly 4:

[0059] It includes a screw transmission flange 41 and a threaded motor 42 installed on the screw transmission flange 41. The output end of the threaded motor 42 is provided with an internal threaded column 43, that is, the output end of the threaded motor 42 is connected to a screw, and the screw is connected to the threaded hole in the internal threaded column 43 along the axial direction of the internal threaded column 43. The threaded motor 42 drives the screw to rotate, so that the internal threaded column 43 can be driven to move axially along the screw 56.

[0060] Of course, the linear drive assembly 4 can be replaced by a hydraulic cylinder or a pneumatic cylinder and a linear motor. However, since it is necessary to perform more precise contact extrusion on the side of the press table and the side of the square box product, the use of a screw drive method can more accurately control the stroke of the internal threaded column 43.

[0061] In terms of the method of connecting the roller body 3, a spring connecting frame 44 perpendicular to the internal threaded column 43 is provided on the outer wall of the internal threaded column 43. The end of the spring connecting frame 44 away from the internal threaded column 43 is connected to the rotating shaft rod 45 set at the end of the roller body 3. The rotating shaft rod 45 is installed at the end of the roller body 3 along the axial direction of the roller body 3.

[0062] Although the present invention uses the compression contact between the roller body 3 and the press table 2, it is desired that the compression contact process has a buffering property, and it is desired that the buffer has an accurate guiding property.

[0063] To this end, the spring connecting frame 44 includes a guide sleeve 46 vertically mounted on the outer side wall of the internal threaded column 43, and a guide column hole 47 is provided in the guide sleeve 46 along the axial direction of the guide sleeve 46. A spline shaft 48 is installed in the guide column hole 47, and a limit spring 49 is provided at one end of the spline shaft 48 located in the guide column hole 47. The other end of the spline shaft 48 is connected to the rotating shaft rod 45. One end of the limit spring 49 is connected to the inner end of the guide column hole 47, and the other end is sleeved on the spline shaft 48.

[0064] Because the structure of the spline shaft 48 is similar to that of a spur gear, the corresponding guide post hole 47 also matches the spline shaft 48, so that the spline shaft 48 and the guide post hole 47 cooperate to provide a fixed guiding function. That is, under the action of the limit spring 49, the spline shaft 48 moves axially along the guide post hole 47. If the spline shaft 48 is a smooth cylindrical structure, it may rotate circumferentially, especially in the ball joint connection between the spline shaft 48 and the rotating shaft rod 45 described below.

[0065] The vertical (or angled) connection between the guide sleeve 46 and the internal threaded column 43 enables the linear drive assembly 4 to obtain stable contact with the side of the press table 2 when driven in the vertical direction.

[0066] Further, in order to achieve the distance adjustment of the linear drive assembly 4 and the roller body 3 as a whole, the adjustment mechanism 5 in the present invention includes a guide bracket 51 connected to the screw transmission flange 41 and along the length direction of the internal threaded column 43, and a first telescopic drive member 52 connected in the middle of the guide bracket 51 and perpendicular to the guide bracket 51. The first telescopic drive member 52 is used to drive the linear drive assembly 4 and the roller body 3 to move close to the side of the forming mold 1.

[0067] Furthermore, after coupling the vertical force driven by the linear drive assembly and the lateral force driven by the adjustment mechanism, the roller body 3 is driven to squeeze and contact the side of the finished square box product to complete the extrusion molding of the side edge portion of the square box product.

[0068] The output end of the first telescopic driving member 52 in the present invention is connected to the top of the guide bracket 51 close to the screw transmission flange 41 through the fixed bracket 53, and the bottom of the first telescopic driving member 52 is connected to the bottom of the guide bracket 51 through the second telescopic driving member 54. The first telescopic driving member 52 and the second telescopic driving member 54 can specifically be a pneumatic cylinder or a hydraulic cylinder.

[0069] During its specific operation, the press table 2 has been separated from the forming mold 1, exposing the upper surface and side of the finished product, so that the screw drive flange 41 is installed on the frame 6 for placing the forming mold through the rotating shaft 55, and the second telescopic drive member 54 is used to drive the screw drive flange 41 to rotate around the rotating shaft 55, so that the internal threaded column 43 rotates around the rotating shaft 55. At this time, there is an angle between the internal threaded column 43 and the vertical direction. At this time, the linear drive component 4 continues to drive the roller body 3 to descend, so that the bottom of the roller body 3 contacts the bottom surface of the square box product (near the side edge).

[0070] Subsequently, the linear drive assembly 4 and the adjustment mechanism 5 work simultaneously, that is, the first telescopic drive member 52 and the second telescopic drive member 54 of the adjustment mechanism 5 cooperate to pull the internal threaded column 43 back to the vertical direction, and then the adjustment mechanism 5 begins to apply a constant force to the roller body 3 along the side of the vertical square box product (transmitted through the screw drive flange 41, the internal threaded column 43 and the guide sleeve 46), and the linear drive assembly 4 drives the roller body 3 to move vertically to contact and extrude the side of the square box product, completing the extrusion shaping of the edge corners at the connection between the side and bottom surfaces of the square box product.

[0071] In the above, if the mold is used to prepare a square disc product with right-angled corners, then the right-angled edges of the square disc product can be shaped by staggered roller bodies with diameter differences. However, in the preparation process of most square disc products or box-shaped products, the corners need to be chamfered to obtain smooth corners. Obviously, chamfering is still required after the roller body 3 works to extrude and shape the side of the square box product.

[0072] Therefore, the present invention proposes a synchronous circular rotation of all roller bodies 3 in the circumference of the forming mold 1 on the basis of arranging roller bodies 3 on all sides of the forming mold 1, so that the roller bodies 3 contact the corners of the square box product in a rotating state, thereby enabling chamfering. Of course, in this process, the linear drive component 4 can also be superimposed to drive the roller bodies 3 to move up and down when contacting the corners of the square box product to perform chamfering.

[0073] That is, the present invention requires that the roller body 3 be able to contact the corner of the square box product during the rotation process, so the roller body 3 rotates from one side of the square box product to the other adjacent side, and the calculation method of its rotation stroke curve can use the theory of a ladder sliding on a right-angled side to obtain its stroke curve, and the corner of the square box product is always in contact with the stroke curve.

[0074] Obviously, the roller body 3 is not a circular trajectory, so two first telescopic driving members 52 located at both ends of the roller body 3 are required to adjust the distance between the two ends of the roller body 3 and the square box product and the circumferential rotation of the superimposed roller body 3, so as to realize the sliding trajectory of the roller body 3 at the right angle wall.

[0075] Therefore, a rotation drive assembly 7 is provided on the frame 6 of the present invention (the frame 6 is designed for the purpose of not hindering the circumferential rotation of the roller body 3), and the linear drive assemblies 4 and the adjustment mechanism 5 of all roller bodies 3 are connected to the rotation drive assembly 7. The rotation drive assembly 7 is used to drive the roller body 3 to rotate circumferentially around the forming mold 1 and switch the position between two adjacent roller bodies 3.

[0076] When the rotary drive assembly 7 drives the roller body 3 to rotate around the circumference of the forming mold 1 , the adjustment mechanism 5 adjusts the rotation radius of the roller body 3 so that the roller body 3 contacts the corner of the product formed by the forming mold 1 .

[0077] Specifically, in order to more clearly illustrate the above working principle, the present invention provides a specific embodiment of a rotary drive assembly 7:

[0078] It includes an annular bracket 71 and a servo motor 73 that drives the annular bracket 71 to rotate in a circular motion. The annular bracket 71 is installed on the frame 6, wherein the interior of the frame 6 is located above the forming mold 1. The annular bracket 71 can rotate relative to the frame 6, that is, the annular bracket 71 needs to be supported by an annular base 74 provided on the frame 6. The annular base 74 and the annular bracket 71 (specifically, an annular plate) can rotate relative to each other, and the annular base is fixedly mounted on the frame 6.

[0079] A plurality of guide grooves 72 are provided along the radial direction of the annular bracket 71 , and the top of the linear drive assembly 4 (that is, the screw transmission flange 41 part) is movably installed in the guide groove 72 , and the adjustment mechanism 5 can drive the linear drive assembly 4 and the roller body 3 to move along the guide groove 72 .

[0080] The main thing is that the adjustment mechanism 5 applies a force to the screw transmission flange 41 along the radial direction parallel to the annular bracket 71, so that the screw transmission flange 41 moves along the guide groove 72, and then the entire structure connected to the screw transmission flange 41 can also move along the direction of the guide groove 72. Specifically, the adjustment mechanisms 5 at both ends of the roller body 3 work synchronously to make the roller body 3 approach or move away from the side of the forming mold.

[0081] Specifically, during chamfering, the adjustment mechanism 5 at one end of the roller body 3 drives the corresponding end of the roller body 3 away from the side of the forming mold, while the other end of the roller body 3 remains stationary. The servo motor 73 drives the annular bracket 71 to begin continuous rotation, and the adjustment mechanism 5 adjusts the movement of one end of the roller body 3. The overall movement is as follows: first moving away from the side of the forming mold 1 (i.e., the side of the square box product), and then moving closer to the side of the forming mold 1. During this movement, the circular rotation of the annular bracket 71 is superimposed, making the movement trajectory of one end of the roller body 3 a continuous curve. This ensures that the roller body 3 maintains a stable contact and extrusion force with the corner of the square box product.

[0082] Since the roller body 3 needs to keep one end away from the forming mold 1 and the other end relatively stationary, it is preferred that the roller body 3 is connected to the spring connecting frame 44 through a ball joint to obtain multi-degree-of-freedom rotation of the end of the roller body 3, that is, the connection between the spline shaft 48 and the rotating shaft rod 45 becomes a ball joint connection.

[0083] Since the annular bracket 71 only needs to rotate at a central angle of about 90° (during this process, the linear drive component 4 also drives the roller body 3 to move upward or downward to complete the movement of the roller body 3 across the width of the square box product), the driving device of the annular bracket 71 can also be a telescopic cylinder (replacing the servo motor 73 in the present invention) arranged along the tangential direction of the annular bracket 71 to cause the annular bracket 71 to rotate circumferentially.

[0084] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
