Description

Technical Field

[0001] This utility model relates to the technical field of injection molding product processing equipment, specifically a fast-pressing and shaping fixture suitable for injection molding products. Background Technology

[0002] Injection molded products refer to products made by heating and plasticizing plastic with an injection molding machine, then injecting it into the cavity of a mold, cooling it down, solidifying the melt, and then demolding it.

[0003] Currently, in injection-molded products such as PCB circuit board support components in fluid flow meter assemblies, the industry generally reduces product deformation by adjusting injection parameters to extend the cooling time. However, this method increases the product start-up production cycle and has problems such as high start-up machine and labor costs.

[0004] Furthermore, since the PCB circuit board design is already finalized, altering the structure of the circuit support components to enhance product strength and prevent deformation would cause interference with the PCB circuit board during installation, making successful installation impossible. Therefore, it is not possible to enhance product strength and reduce product deformation by changing the product structure. Utility Model Content

[0005] The purpose of this invention is to provide a fast-pressing and shaping fixture suitable for injection molded products, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-press forming fixture suitable for injection molded products includes:

[0008] A base, wherein the middle part of the base has a positioning area;

[0009] A first clamp is mounted on a pad, and the pad is mounted on a base;

[0010] The second clamp is mounted on the base;

[0011] The positioning area is used to place the injection molded product, and the positioning area has an outer arc-shaped structural surface; the injection molded product has a deformable surface, which includes the upper surface and the bottom surface of the injection molded product;

[0012] The first clamp is used to press one side of the upper surface of the injection molded product, and the second clamp is used to press the other side of the upper surface of the injection molded product.

[0013] After the first and second clamps press the injection molded product together, the bottom surface of the injection molded product fits and conforms to the outer arc-shaped structural surface.

[0014] After the first and second clamps release the injection molded product, the bottom surface of the injection molded product leaves the outer arc-shaped structural surface and springs back to a horizontal state.

[0015] Furthermore, the positioning area also has a horizontal plane, and the outer arc-shaped structural surfaces are located on both sides of the horizontal plane. A central positioning hole and side holes are provided on the horizontal plane. The central positioning hole is used for the insertion of the fixing part in the middle of the bottom surface of the injection molded product, and the side holes are used for the insertion of the pins on both sides of the injection molded product.

[0016] Furthermore, the structure and shape of the first and second clamps.

[0017] Furthermore, both the first and second clamps include a support, a pressure handle, a rotating handle, and a screw. The support is mounted on the base, the rotating handle is hinged to the support, the pressure handle is hinged to the support via a connecting rod, and the pressure handle is also hinged to the rotating handle. The screw is adjustablely mounted to the rotating handle and is used to connect a first or second pressure block for pressing the upper surface of the injection molded product.

[0018] Furthermore, the pressure handle is equipped with a grip, the rotating handle has a slot, the screw can be adjusted in position within the slot, and the screw is fitted with two upper and lower stop washers and a locking nut, which fix the screw and the slot relative to each other.

[0019] Furthermore, the upper surface of the injection molded product has a groove for pressing the first pressure block and a through groove for pressing the second pressure block.

[0020] Furthermore, when the bottom surface of the injection molded product is fitted to the outer arc-shaped structural surface, the arc length of the bottom surface of the injection molded product is one-third to one-half of the arc length of the outer arc-shaped structural surface.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention uses an outer arc-shaped structural surface as the contact surface with the deformation surface of the injection molded product, so that the injection molded product has a reverse deformation amount. When the molding is completed and the injection molded product is taken out, the injection molded product just springs back to the horizontal, which meets the assembly and use requirements.

[0023] This invention features a quick-press chuck design for the first and second clamps on both sides, allowing for fast and convenient clamping and unloading of injection-molded products. By using a dedicated quick-press, outer arc-shaped forming fixture, product shaping is achieved, reducing injection molding machine start-up cooling time, shortening the production cycle, and improving efficiency. This reduces machine operating hours and manual start-up time, lowering costs and enhancing competitiveness. Attached Figure Description

[0034] Please see Figures 1 to 6 This utility model provides a technical solution:

[0035] A quick-press forming fixture suitable for injection molded products includes:

[0036] The base 6 has a positioning area 12 in the middle.

[0037] The first clamp 8 is mounted on the pad 7, and the pad 7 is mounted on the base 6;

[0038] The second clamp 9 is mounted on the base 6;

[0039] The positioning area 12 is used to place the injection molded product 1, and the positioning area 12 has an outer arc-shaped structural surface 23;

[0040] The first clamp 8 is used to press one side of the upper surface of the injection molded product 1, and the second clamp 9 is used to press the other side of the upper surface of the injection molded product 1.

[0041] After the first clamp 8 and the second clamp 9 press the injection molded product 1 together, the bottom surface of the injection molded product 1 is adapted to fit and conform to the outer arc-shaped structural surface 23.

[0042] When the first clamp 8 and the second clamp 9 release the injection molded product 1, the bottom surface of the injection molded product 1 leaves the outer arc-shaped structural surface 23 and springs back to a horizontal state.

[0043] Specifically, the positioning area 12 also has a horizontal surface 13, and the outer arc-shaped structural surface 23 is located on both sides of the horizontal surface 13. A central positioning hole 15 and a side hole 14 are provided on the horizontal surface 13. The central positioning hole 15 is used for inserting the fixing part 6 in the middle of the bottom surface of the injection molded product 1, and the side hole 14 is used for inserting the pins 5 on both sides of the injection molded product 1.

[0044] In this utility model, the injection molded product 1 is a PCB circuit board support in the fluid flow meter assembly. The upper end face of the injection molded product 1 has a groove 2, a through groove 3 and a mounting foot 4. The middle of the bottom surface has an outwardly protruding fixing part 6. The side of the injection molded product 1 has a pin 5. The groove 2 and the through groove 3 facilitate the insertion of the first pressure block 10 and the second pressure block 11 and press the injection molded product 1 onto the base 6. The mounting foot 4, the pin 5 and the fixing part 6 facilitate the installation of the injection molded product 1 into the housing of the fluid flow meter assembly.

[0045] The fixture of this utility model clamps, after the injection molding machine has started producing injection molded product 1, to clamp, position and shape the injection molded product, thereby reducing the deformation of the injection molded product, meeting the customer's assembly and use requirements, shortening the production cycle and improving efficiency.

[0046] This invention, considering the structural characteristics of injection-molded product 1, adopts an outer arc-shaped structural surface 23 as the bonding surface of injection-molded product 1, with quick-press chucks on both upper sides. This design achieves product shaping without increasing the injection molding machine's start-up cooling time or production cycle. In current manufacturing, this is highly practical for reducing manufacturing costs, shortening production cycles, improving product deformation, and enhancing product quality and competitiveness. It has broad application prospects in the production of similar products and is of great significance for improving production efficiency.

[0047] The following is a detailed introduction:

[0048] Specifically, the structure and shape of the first clamp 8 and the second clamp 9. Both the first clamp 8 and the second clamp 9 include a support 17, a pressure handle 16, a rotating handle 18, and a screw 24. The support 17 is mounted on the base 6. The rotating handle 18 is hinged to the support 17. The pressure handle 16 is hinged to the support 17 via a connecting rod 19, and is also hinged to the rotating handle 18. The screw 24 is adjustablely mounted to the rotating handle 18 and is used to connect to a first pressure block 10 or a second pressure block 11 for pressing the upper surface of the injection-molded product 1. The pressure handle 16 is equipped with a grip 22. The rotating handle 18 has a slot 20. The screw 24 can be adjusted in position within the slot 20. Two upper and lower stop washers 25 and a locking nut 21 are fitted onto the screw 24, and the upper and lower locking nuts 21 and the stop washers 25 fix the screw 24 relative to the slot 20.

[0049] like Figures 3 to 5 As shown, when the injection-molded product 1 is placed in the positioning area 12 of the base 6, the fixing part 6 is inserted into the central positioning hole 15, and the two pins 5 are respectively inserted into the two side holes 14. At this time, the injection-molded product 1 completes the initial positioning. Then, both the left and right sides simultaneously move downwards (i.e., Figure 6(In the opposite direction of the middle arrow F) Press the handle 22. Since pin b passes through pin hole c and pin a passes through pin hole d, and after pin b and pin hole c are installed, connecting rod 19 can rotate on support 17 with the other end. When the handle 22 is pressed down, pin b rotates relative to pin hole c, the bottom end e of the pressure handle 16 presses the connecting rod 19 into the clearance groove f, and at the same time pin a rotates relative to pin hole d, causing the handle 18 to press down. In this way, the screw 24 drives the first pressure block 10 and the second pressure block 11 to press down on the upper surface of the injection molded product 1 until... Figure 6 As shown, when the bottom surface of the injection molded product 1 is in contact with the outer arc-shaped structural surfaces 23 on both sides, the bottom end e of the pressure handle 16 reaches the bottom of the clearance groove f, and the pressure handle 22 can be stopped. At this time, the pressure handle 16 can maintain the downward pressure on the rotating handle 18, press the injection molded product 1, and realize product shaping.

[0050] After maintaining this for a period of time, such as Figure 6 As shown, lift the pressure handle 16 in the direction of arrow F. This will cause the pressure handle 16 to drive the rotating handle 18 to rise, thereby lifting the first pressure block 10 and the second pressure block 11 respectively, so that the molded injection product 1 can be taken out.

[0051] Specifically, the positioning area 12 also has a horizontal surface 13, and the outer arc-shaped structural surfaces 23 are located on both sides of the horizontal surface 13. A central positioning hole 15 and side holes 14 are provided on the horizontal surface 13. The central positioning hole 15 is used for inserting the fixing part 6 in the middle of the bottom surface of the injection molded product 1, and the side holes 14 are used for inserting the pins 5 on both sides of the injection molded product 1. The upper end surface of the injection molded product 1 has a groove 2 for pressing the first pressure block 10 and a through groove 3 for pressing the second pressure block 11. It should be noted that the second pressure block 11 spans across the through groove 3 but does not leak down into the through groove 3. The first pressure block 10 is concave, and the second pressure block 11 is elongated.

[0052] This utility model, such as Figure 5 As shown, the handle 18 has a strip groove 20, and the screw 24 is fitted with two stop washers 25 and a locking nut 21. The two stop washers 25 are located at the upper and lower ends of the strip groove 20, respectively. When the screw 24 passes through the strip groove 20, the two locking nuts 21 are tightened, thereby locking the two stop washers 25 with the upper and lower ends of the strip groove 20, thus fixing the screw 24. When it is necessary to adjust the pressing position of the first pressure block 10 and the second pressure block 11 on the upper end face of the injection molded product 1, the two locking nuts 21 are loosened, allowing the screw 24 to move left and right in the strip groove 20.

[0053] Specifically, when the injection-molded product 1 is pressed onto the base 6, the bottom surface of the injection-molded product 1 fits snugly against the outer arc-shaped structural surface 23, and the arc length of the bottom surface of the injection-molded product 1 is one-third to one-half of the arc length L of the outer arc-shaped structural surface 23. This not only prevents the injection-molded product 1 from shifting and achieves product shaping, but also avoids excessive pressure that would cause permanent deformation of the injection-molded product 1 and prevent the generation of reverse deformation.

[0054] During injection molding, the injection molded product 1 is inside the mold. Increasing the holding pressure and cooling time during injection molding can improve the deformation of the injection molded product 1 to a certain extent. However, with the fixture of this utility model, it is not necessary to increase the holding pressure and cooling time during injection molding, and the injection molding production cycle will not be lengthened.

[0055] The parts of this utility model not described are existing technologies.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
