Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic mold technology, specifically relating to a temperature-measuring and heating plastic mold. Background Technology
[0002] Plastic mold is a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes of the mold's punch and die, as well as the auxiliary molding system, can produce a series of plastic parts of different shapes and sizes.
[0003] Currently, plastic molds typically require preheating before production to avoid low product yield. However, existing plastic molds usually only preheat the bottom, resulting in excessively long preheating times and difficulty in uniformly heating the interior and exterior, thus reducing preheating efficiency and hindering normal use. Furthermore, the excessive pressure between the upper and lower molds during production can easily cause wear, accelerating mold aging, reducing lifespan, and diminishing practicality. Utility Model Content
[0004] The purpose of this invention is to provide a temperature-measuring and heating plastic mold to solve the problems of existing plastic molds, which can usually only preheat the bottom during heating and are prone to wear between the upper and lower molds during production.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature-measuring and heating plastic mold, comprising: a base plate, a bracket connected to the top of the base plate, a hydraulic pump installed on the top of the bracket, the output end of the hydraulic pump penetrating through the top of the bracket and connected to an upper mold, a connecting block connected to the top of the base plate, a lower mold placed on the top of the connecting block, and an injection port provided on the top of the upper mold; a heating assembly, the heating assembly being disposed inside the connecting block, the heating assembly including a heating groove, the heating groove being opened on the top of the connecting block, the lower mold placed inside the heating groove, a water tank being opened inside the connecting block, an inlet pipe being connected through the water tank to one side of the connecting block, and an outlet pipe being connected through the water tank to the other side of the connecting block, and a heat-conducting plate being embedded inside the heating groove, the heat-conducting plate being arranged in a concave structure.
[0006] Preferably, the top of the lower mold and the bottom of the upper mold are provided with protective components. The protective components include grooves. Two grooves are symmetrically opened on the top of the lower mold, and springs are connected to the bottom side of the inner wall of the two grooves. A pressure plate is connected to the top of the springs, and pressure rods are symmetrically connected to both sides of the bottom of the upper mold.
[0007] Preferably, a temperature sensor is installed on one side of the inner wall of the heating tank, and a temperature display is installed on one side of the outer wall of the connecting block.
[0008] Preferably, a support block is connected between the two sides of the inner wall of the water tank, and a drain pipe is connected through the water tank and one side of the connecting block.
[0009] Preferably, a rubber pad is provided on the top of the lower mold.
[0010] Preferably, both of the grooves are connected to annular limiting plates inside.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] (1) By setting up a heating component, the heating liquid is poured into the water tank through the water inlet pipe. After the water tank is full of heating liquid, the heating liquid is discharged from the water tank through the water outlet pipe, so that the heating liquid inside the water tank is always in a flowing state. Then, the heat can be conducted to the heating tank through the heat conduction plate, thereby heating the lower mold inside the heating tank. This achieves uniform heating of the plastic mold inside and around, reduces the preheating time of the mold, greatly improves the preheating efficiency of the plastic mold, and is beneficial to the normal use of the plastic mold.
[0013] (2) By setting up protective components, when it is necessary to press the upper mold and the lower mold, the pressure rods on both sides of the bottom of the upper mold will be inserted into the groove at the top of the lower mold. As the lower mold continues to descend, the pressure rods will continuously press down on the pressure plate, causing the spring to be compressed inside the groove. This effectively relieves the pressure between the upper mold and the lower mold, avoids wear between the upper mold and the lower mold, reduces the aging speed of the plastic mold, and improves the practicality of the plastic mold.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1-3 As shown, this utility model provides the following technical solution: a temperature-measuring and heating plastic mold, comprising: a base plate 1, a bracket 2 connected to the top of the base plate 1, a hydraulic pump 3 installed on the top of the bracket 2, the output end of the hydraulic pump 3 passing through the top of the bracket 2, and the output end of the hydraulic pump 3 connected to an upper mold 4, a connecting block 5 connected to the top of the base plate 1, a lower mold 6 placed on the top of the connecting block 5, and an injection port 15 provided on the top of the upper mold 4; a heating component, the heating component being disposed inside the connecting block 5, the heating component including a heating groove 7, the heating groove 7 being opened on the top of the connecting block 5, the lower mold 6 being placed inside the heating groove 7, a water tank 9 being opened inside the connecting block 5, a water inlet pipe 10 being connected through the water tank 9 to one side of the connecting block 5, and a water outlet pipe 11 being connected through the water tank 9 to the other side of the connecting block 5, and a heat-conducting plate 12 being embedded inside the heating groove 7, the heat-conducting plate 12 being arranged in a concave structure.
[0020] Through the above technical solution:
[0021] Specifically, when the lower mold 6 needs to be heated, the heating liquid is poured into the water tank 9 through the water inlet pipe 10. After the water tank 9 is full of heating liquid, the heating liquid is discharged from the water tank 9 through the water outlet pipe 11, so that the heating liquid inside the water tank 9 is always in a flowing state, and the temperature inside the water tank 9 can be maintained. Then, the heat can be conducted to the heating tank 7 through the heat conduction plate 12, so that the lower mold 6 inside the heating tank 7 can be heated as a whole.
[0022] Further embodiments are provided in this utility model, see below. Figures 1-3The top of the lower mold 6 and the bottom of the upper mold 4 are provided with protective components. The protective components include grooves 16. Two grooves 16 are symmetrically opened on the top of the lower mold 6, and springs 17 are connected to the bottom side of the inner wall of the two grooves 16. A pressure plate 18 is connected to the top of the springs 17. Pressure rods 20 are symmetrically connected to both sides of the bottom of the upper mold 4.
[0023] Through the above technical solution:
[0024] Specifically, when the upper mold 4 needs to press the lower mold 6, the pressure rods 20 on both sides of the bottom of the upper mold 4 will be inserted into the groove 16 at the top of the lower mold 6. As the lower mold 6 continues to descend, the pressure rods 20 will continuously press down on the pressure plate 18, causing the spring 17 to be compressed inside the groove 16, thereby effectively relieving the pressure between the upper mold 4 and the lower mold 6.
[0025] Reference Figures 1-3 A temperature sensor 8 is installed on one side of the inner wall of the heating tank 7, a temperature display 22 is installed on one side of the outer wall of the connecting block 5, a support block 13 is connected between the two sides of the inner wall of the water tank 9, and a drain pipe 14 is connected through the water tank 9 and one side of the connecting block 5. A rubber pad 19 is provided on the top of the lower mold 6, and an annular limiting plate 21 is connected inside the two grooves 16.
[0026] Through the above technical solution:
[0027] Specifically, the temperature inside the heating tank 7 can be monitored in real time by setting a temperature sensor 8 and a temperature display 22. The stability inside the heating tank 7 is increased by setting a support block 13. The heating liquid inside the water tank 9 can be drained by setting a drain pipe 14. The wear between the lower mold 6 and the upper mold 4 is effectively reduced by setting a rubber pad 19. The position of the pressure plate 18 inside the groove 16 can be restricted by setting an annular limiting plate 21.
