Description

Technical Field

[0001] The invention relates to the technical field of plastic molding, and in particular to a modular polymer plastic molding machine which is easy to assemble and a use method thereof. Background Art

[0002] In the field of polymer plastic molding, the quality of plastic products has always been a key concern in the production process. With the continuous development of the manufacturing industry, higher requirements are placed on the precision, strength and appearance quality of plastic products.

[0003] Traditional polymer plastic molding machines, whether they are monolithic structures or early modular designs, face many problems during the molding process, especially the problem of bubbles in the plastic melt. During the melting stage of plastic particles, the moisture and volatile substances contained in the raw materials, as well as the air drawn in during the plasticization process, will cause bubbles to form in the plastic melt. These bubbles form defects such as cavities and pores in the molded plastic products, greatly reducing the strength and appearance quality of the products. For example, when producing precision electronic parts housings, internal bubbles will affect the structural strength of the products and reduce the reliability of the products. When producing plastic products with high appearance requirements, such as automotive interior parts, bubbles will seriously affect the aesthetics of the products.

[0004] Currently common methods for removing bubbles, such as mold exhaust and raw material drying, are helpful to a certain extent, but still have limitations. The mold exhaust system can only exhaust the air in the cavity, but is powerless against bubbles that have already formed inside the plastic melt; raw material drying is also difficult to completely eliminate the bubbles caused by raw material characteristics and production environment. Moreover, when facing different product requirements, the assembly and debugging process of traditional molding machines is cumbersome and the production efficiency is low.

[0005] Therefore, the development of a modular polymer plastic molding machine that can effectively solve the problem of plastic melt bubbles and is easy to assemble has become an urgent problem to be solved in the industry. After searching, it was found that the prior art publication number is CN214872608 U, discloses a polymer plastic parts hot pressing molding machine, including a body base, a body shell is fixedly installed on the top of the body base, support legs are fixedly installed at the four corners of the lower surface of the body base, a pressing push rod is fixedly installed on the top of the body shell, a control panel is fixedly installed on the front surface of the body shell, a discharge mechanism is fixedly installed in the body shell, the discharge mechanism includes a limiting notch, a movable slide groove, a limiting frame, a hot pressing lower mold, an ejection through hole, a mold cavity and a sliding support foot, an ejection mechanism is fixedly installed at the bottom of the hot pressing lower mold, the ejection mechanism includes an ejection cap, an electric push rod, a heat insulation gasket, a connecting base and a connecting through hole, the limiting frame is fixedly installed in the body shell, and the polymer plastic parts hot pressing molding machine described in the utility model belongs to the field of hot pressing molding machines, can improve processing efficiency, and reduce the occurrence of safety accidents.

[0006] Therefore, when the above scheme is used, the plastic particles that need to be shaped are simply heated and shaped. However, since the bubbles in the molten plastic solution cannot be effectively removed during the heating process, it has limitations. In order to solve the problem of effectively removing the bubbles in the melted plastic solution, we propose a modular polymer plastic molding machine that is easy to assemble and a method of use.

[0015] As a further feature of the present invention, a matching tube is fixedly connected to the upper end of the matching barrel, and the matching tube is communicated with the matching barrel.

The matching rod then drives the knocking block to knock the outer wall of the matching barrel at a high frequency and quickly. The mechanical vibration generated by the knocking is quickly transmitted to the melted plastic particles in the matching barrel. Under the action of the vibration, the force on the bubbles in the plastic solution changes.

The inside of the moving box 13 is also fixedly connected to a matching barrel 22. The matching barrel 22 is made of metal. When the heating ring 11 is energized, an alternating magnetic field will be generated. According to the principle of electromagnetic induction, an induced current eddy current will be generated inside the matching barrel 22 in the alternating magnetic field.

The shrink sleeve 27 and The matching barrel 22 is connected, and a plurality of through-holes 28 are provided at the bottom of the matching barrel 22 and the bottom of the moving box 13. The plurality of through-holes 28 are distributed circumferentially at the bottom of the moving box 13 and the matching barrel 22, respectively. The through-holes 28 at the bottom of the matching barrel 22 are connected to the corresponding through-holes 28 at the bottom of the moving box 13. A plurality of abutment rods 18 are fixedly connected to the bottom end of the inner wall of the abutting outer tube 8. The plurality of abutment rods 18 are distributed circumferentially at the bottom end of the inner wall of the abutting outer tube 8, and each abutment rod 18 is located directly below the adjacent through-holes 28.

[0040] See also Figure 4 , Figure 5 , Fig. 9 , Fig.10As shown, the discharge mechanism 101 includes a first abutting tube 12, the first abutting tube 12 is fixedly connected to the bottom of the collecting bucket 9, and the first abutting tube 12 is communicated with the collecting bucket 9, the inner wall of the first abutting tube 12 is slidably connected to a first blocking block 20 with a reset function, and the first blocking block 20 is wide at the bottom and narrow at the top. Specifically, a first connecting rod 21 is fixedly connected to the bottom of the first blocking block 20, and the outer wall of the first connecting rod 21 is slidably connected to the inner wall of the first abutting tube 12. A third reset spring is fixedly connected between the first connecting rod 21 and the first abutting tube 12, and the third reset spring is sleeved on the outer wall of the first connecting rod 21. The third reset spring can drive the first connecting rod 21 and the first block 20 to reset quickly;

[0041] The upper end of the matching barrel 22 is also fixedly connected with a matching tube 40, and the matching tube 40 is connected to the matching barrel 22.

[0042] See also Figure 5 - Figure 8 As shown, the vibration knocking mechanism 301 includes two racks 23, the two upper racks 23 are fixedly connected to the inner wall of the outer tube 8, and the two racks 23 are symmetrically distributed in the inner wall of the outer tube 8, and the left and right ends of the moving box 13 are slidably connected with a plurality of matching rods 30 with a reset function.

[0044] See also Figure 2 , Figure 6As shown, a connecting tube 14 is fixedly connected to the outer wall of the matching barrel 22. The connecting tube 14 is made of silicone rubber. Silicone rubber has excellent elasticity and its molecular chain is relatively soft. When subjected to external force, it can undergo a large degree of deformation, and when the external force is removed, it can quickly return to its original shape. A pressure valve is fixedly installed inside the connecting tube 14. Two molds 38 are arranged inside the third assembly frame 6. One of the molds 38 is fixedly connected to the inner wall of the third assembly frame 6 and is also fixedly connected to the connecting tube 14. An electric telescopic arm 39 is fixedly connected to the inner wall of the third assembly frame 6. The output end of the electric telescopic arm 39 is fixedly connected to another mold 38. The mold 38 is a prior art and will not be described in detail herein. A collection box 7 is slidably connected to the bottom end of the inner wall of the third assembly frame 6.

[0045] The working principle of the present invention is as follows: when in use, it is only necessary to fill the collecting barrel 9 with plastic particles, at which time the servo motor 17 is started to rotate, the servo motor 17 drives the recovery wheel 15 to release the pull rope 16, and the elastic reset of the second reset spring 19 drives the moving box 13 to move upward, when the moving box 13 drives the matching barrel 22 to move upward, the matching tube 40 inside the matching barrel 22 drives the second connecting rod 26 to abut against the first connecting rod 21, and at this time the collecting barrel 9 and the matching tube 40 are also abutted and connected to each other, and at this time the first blocking block 20 and the second blocking block 36 connected to the two move in opposite directions, and the plastic particles inside the collecting barrel 9 will enter the matching barrel 22 through the first abutting tube 12 and the matching tube 40;

[0046] When the inside of the matching barrel 22 is filled, the servo motor 17 is started to drive the recovery wheel 15 to rotate in the opposite direction. The recovery wheel 15 pulls the pull rope 16, and the pull rope 16 drives the mobile box 13 and the matching barrel 22 to move downward. All the matching barrels 22 will pass through the heating ring 11, and the heating ring 11 will heat and melt the plastic particles inside the matching barrel 22. By controlling the speed of the recovery pull rope 16, the time for the matching barrel 22 to pass through the heating ring 11 can be controlled to ensure that the particles can be melted. When the mobile box 13 moves downward, the second connecting rod 26 is disengaged from the first connecting rod 21, and the first blocking block 20 and the second blocking block 36 are reset. When the roller 31 quickly abuts against the teeth on the outer wall of the rack 23, the matching rod 30 drives the knocking block 29 to quickly knock on the outer wall of the matching barrel 22, so that the matching barrel 22 vibrates, so that the bubbles inside the melted plastic particles float upward on the surface of the solution. It is worth noting that the liquid surface of the plastic solution does not abut the annular block 32. When it abuts When the rod 18 passes through the through-hole 28 to abut against the movable piston 35, the coordinated barrel 22 moves downward as a whole, and the movable piston 35 cooperates with the inside of the barrel 22 to perform an extrusion action. The movable piston 35 will squeeze the plastic solution into the inside of the shrink sleeve 27, and the groove 34 inside the movable piston 35 will fit well with the bottom of the second blocking block 36. At this time, the bubbles on the liquid surface of the plastic solution will be inside the shrink sleeve 27. At this time, the shrink sleeve 27 is stretched to the limit, and the movable piston 35 is squeezed again. At this time, the abutting circular ring block 32 will abut against the bottom of the shrink sleeve 27 to block the bottom of the shrink sleeve 27. Since the pressure inside the coordinated barrel 22 increases, the pressure valve inside the connecting pipe 14 will be triggered to open, and the abutting circular ring block 32 can effectively prevent bubbles from entering the connecting pipe 14. At this time, it is necessary to start the electric telescopic arm 39 in advance to drive the mold 38 and the other mold 38 to close each other. When the solution inside the connecting pipe 14 enters the two molds 38, the two molds 38 shape the plastic melt;

[0047] After use, the servo motor 17 drives the recovery wheel 15 to rotate, and the recovery wheel 15 drives the mobile box 13 to reset through the pull rope 16. At this time, the abutment rod 18 will be separated from the abutment with the mobile piston 35, and the fifth reset spring 37 drives the mobile piston 35 and the abutment ring block 32 to reset. When the abutment ring block 32 is separated from the abutment with the bottom of the shrink sleeve 27, the plastic solution will flow to the bottom end of the inner wall of the matching barrel 22, and the next use can be carried out without being affected;

[0048] It is worth noting that during modular assembly, it is only necessary to fix the first assembly frame 4, the second assembly frame 5, and the third assembly frame 6 to each other through nuts, and then abut the upper end of the outer tube 8 against the bottom of the collecting barrel 9, and fix the connecting tube 14 to the adjacent mold 38. The installation is simple and convenient.

[0049] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.

10. A method for using a modular polymer plastic molding machine that is easy to assemble, applied to the modular polymer plastic molding machine that is easy to assemble as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1: Start the servo motor (17) to rotate, the servo motor (17) drives the recovery wheel (15) to release the pull rope (16), and the mobile box (13) moves upward in the reset state. When the mobile box (13) drives the matching barrel (22) to move upward, the matching tube (40) inside the matching barrel (22) drives the second connecting rod (26) and the first connecting rod (21) to abut against each other. At this time, the collection barrel (9) and the matching tube (40) are also abutted and connected to each other. At this time, the first blocking block (20) and the second blocking block (36) connected to the two move in opposite directions, and the plastic particles inside the collection barrel (9) will enter the inside of the matching barrel (22) through the first abutting tube (12) and the matching tube (40); S2: When the inside of the matching barrel (22) is filled, the servo motor (17) is started to drive the recovery wheel (15) to rotate in the opposite direction, and the recovery wheel (15) pulls the pull rope (16), and the pull rope (16) drives the moving box (13) and the matching barrel (22) to move downward, and the heating ring (11) heats and melts the plastic particles inside the matching barrel (22), and the second connecting rod (26) and the first connecting rod (21) are disengaged from the abutment, and the first blocking block (20) and the second blocking block (36) are reset. When the roller (31) quickly abuts against the teeth on the outer wall of the rack (23), the matching rod (30) drives the knocking block (29) to quickly knock on the outer wall of the matching barrel (22), so that the matching barrel (22) vibrates, so that the bubbles inside the melted plastic particles float upward on the surface of the solution; S3: The bubbles on the liquid surface of the plastic solution will be inside the shrink sleeve (27). At this time, the shrink sleeve (27) shrinks to the limit. When the piston (35) is moved to squeeze again, the abutting ring block (32) will abut against the bottom of the shrink sleeve (27) to block the bottom of the shrink sleeve (27). The pressure valve inside the connecting pipe (14) will be triggered to open. The abutting ring block (32) can effectively prevent bubbles from entering the inside of the connecting pipe (14). At this time, it is necessary to start the electric telescopic arm (39) in advance to drive the mold (38) and the other mold (38) to close each other. When the solution inside the connecting pipe (14) enters the inside of the two molds (38), the two molds (38) shape the plastic solution.
