Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology, specifically to a hot pressing fixture for hot deformation treatment of PC material. Background Technology

[0002] Plastic pumps are important components commonly used in fluid transportation, chemical, and medical fields. Their structure typically includes key components such as pump body, pump cover, and impeller. Some components require hot pressing to form and connect plastic materials. Hot pressing allows plastic parts to be heated and softened before being pressed into specific shapes by molds. It is a key process to ensure the dimensional accuracy and structural strength of various components of plastic pumps, and is widely used, especially in the assembly of multiple parts or the processing of complex curved surfaces. Existing hot pressing fixtures typically employ a structure with upper and lower molds working together. After the workpiece is placed in the positioning area of ​​the lower mold, the upper mold moves downward under the action of the drive mechanism. The mold and workpiece are heated by a heating device, and pressure is applied to deform the workpiece in the mold cavity and make it fit the mold surface. After cooling and solidification, the processing is completed.

[0003] However, in actual processing, existing hot press fixtures have significant shortcomings: for long strip or thin sheet workpieces, due to the uneven pressure distribution between the central and edge areas when the mold applies pressure, and the difference in heat dissipation rate and deformation shrinkage at both ends of the workpiece during heating and cooling, the workpiece is prone to warping upwards at both ends after demolding. This warping deformation will cause the overall shape of the workpiece to deviate from the design dimensions, which not only affects the appearance quality of the workpiece, but may also lead to fitting errors during subsequent assembly, and even reduce the sealing performance and mechanical strength of plastic pump components, thereby adversely affecting the overall performance and service life of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a hot pressing fixture for heat deformation treatment of PC material, so as to solve the technical problem that in the prior art, long strip or thin sheet workpieces are prone to the phenomenon of both ends curling up after demolding due to the uneven pressure distribution between the central area and the edge area when the mold is applied, and the difference in heat dissipation rate and deformation shrinkage at both ends of the workpiece during heating and cooling.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution: A hot pressing fixture for heat deformation treatment of PC material includes a hot pressing fixture; a lower pressing block is fixedly connected to the side end of the hot pressing fixture; a pressing groove is formed inside the lower pressing block; an upper pressing block is slidably connected above the lower pressing block at the side end of the hot pressing fixture; a processing hot block is fixedly connected to the bottom end of the upper pressing block, and the processing hot block corresponds to the pressing groove; a limiting unit is provided at the side end of the upper pressing block.

[0006] As a further embodiment of this utility model: the limiting unit includes a cylinder; the cylinder is fixedly connected to the side end of the upper pressure block; a positioning plate is fixedly connected to the bottom end of the cylinder; and a limiting base plate is fixedly connected to the side end of the lower pressure block.

[0007] As a further embodiment of this utility model: a first conveyor belt is provided on the side end of the hot press fixture; a second electric slide rail is provided on the side end of the hot press fixture; the bottom end of the second electric slide rail is slidably connected to the first electric slide rail; an electric push rod is slidably connected to the bottom end of the first electric slide rail; an electric suction cup is fixedly connected to the bottom end of the electric push rod, and the electric suction cup is located on the side close to the hot press fixture.

[0008] As a further embodiment of this utility model: a second conveyor belt is provided on the side end of the hot pressing fixture; an electric fan is fixedly connected to the side end of the second conveyor belt.

[0009] The beneficial effects of this utility model are as follows: After the PC material workpiece is placed on the lower pressure block, the upper pressure block and the processing hot block are heated at high temperature by internal heating wires. The upper pressure block is moved downward by the hot pressing fixture, and the cylinder causes the positioning plate to limit the two ends of the workpiece. The limiting base plate can limit the bottom ends of the two ends of the workpiece. Through the cooperation of the positioning plate and the limiting base plate, the two ends of the workpiece can be prevented from curling up during hot pressing. The hot pressing fixture causes the processing hot block to press the workpiece into the inside of the pressing groove, and the PC material workpiece is hot-pressed into an arc shape. This avoids the difference between the heat dissipation rate and the degree of deformation shrinkage at both ends of the workpiece during the heating and cooling process, which would cause the two ends of the workpiece to curl up after demolding, thus improving the hot pressing processing quality.

[0014] After the PC material workpiece is placed on the lower pressure block 2, the upper pressure block 4 and the processing hot block 5 are heated at high temperature by internal heating wires. The upper pressure block 4 is moved downward by the hot pressing fixture 1, and the cylinder 7 causes the positioning plate 8 to limit the two ends of the workpiece. The limiting base plate 6 can limit the bottom ends of the two ends of the workpiece. Through the cooperation of the positioning plate 8 and the limiting base plate 6, the two ends of the workpiece can be prevented from curling up during hot pressing. The hot pressing fixture 1 causes the processing hot block 5 to press the workpiece into the inside of the pressing groove 3, and the PC material workpiece is hot pressed into an arc shape. This avoids the difference between the heat dissipation rate and the degree of deformation shrinkage at both ends of the workpiece during the heating and cooling process, which would cause the two ends of the workpiece to curl up after demolding, thus improving the hot pressing processing quality.

[0015] The limiting unit includes a cylinder 7; the cylinder 7 is fixedly connected to the side end of the upper pressure block 4; a positioning plate 8 is fixedly connected to the bottom end of the cylinder 7; and a limiting base plate 6 is fixedly connected to the side end of the lower pressure block 2.

[0016] The cylinder 7 causes the positioning plate 8 to limit the two ends of the workpiece. The limiting base plate 6 can limit the bottom ends of the two ends of the workpiece. Through the cooperation of the positioning plate 8 and the limiting base plate 6, the two ends of the workpiece can be prevented from lifting when hot pressing. The hot pressing fixture 1 causes the processing hot block 5 to press the workpiece into the inside of the pressing groove 3, and the PC material workpiece is hot pressed into an arc shape.

[0017] During operation, the PC material workpiece is transported to one side of the hot press fixture 1 via the first conveyor belt 9. The first electric slide rail 11 and the electric suction cup 13 are moved to the top of the first conveyor belt 9 via the second electric slide rail 15. The electric suction cup 13 is moved downward via the electric push rod 12 to pick up the workpiece on the first conveyor belt 9. Then, in conjunction with the second electric slide rail 15 and the electric suction cup 13, the workpiece is moved to one side of the hot press fixture 1. At this time, the electric suction cup 13 is moved in the direction of the workpiece towards the lower pressing block 2 via the first electric slide rail 11 to place the workpiece on the lower pressing block 2. No manual loading is required, which improves work efficiency. The hot press fixture 1 has a second conveyor belt 10 on its side end; an electric fan 14 is fixedly connected to the side end of the second conveyor belt 10.

[0018] After the workpiece is processed on the hot press fixture 1, the electric push rod 12 and electric suction cup 13 are moved onto the workpiece by the first electric slide rail 11.

[0019] The working principle of this utility model is as follows: During operation, the PC material workpiece is transported to one side of the hot press fixture 1 via the first conveyor belt 9.

Then, in conjunction with the second electric slide rail 15 and the electric suction cup 13, they are moved to one side of the hot press fixture 1. At this time, the electric suction cup 13 is moved in the direction of the workpiece downward pressing block 2 via the first electric slide rail 11, placing the workpiece on the lower pressing block 2.
