Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a mold shaping device for waterproof composite materials. Background Art

[0002] Plastic molds are molds used for the production of waterproof composite materials (usually plastic) products. Plastic molds are usually made of metal (such as steel, aluminum, etc.) and have a cavity or structure that matches the shape and size of the final plastic product. In the plastic mold, the heated plastic particles are injected into the mold, and the plastic is fully filled in the mold cavity through pressure and temperature control. After cooling, the mold is taken out to obtain the molded plastic product.

[0003] The Chinese patent with publication number CN219153519U discloses a plastic mold shaping device, which conveys coolant to the water channel through the cooperation of a circulating pump, a tee pipe, a cooling pipe, a water pipe, and a water channel, so that the coolant directly contacts the lower mold, thereby improving the cooling effect. At the same time, the coolant is also conveyed to the cooling pipe, and the cooling pipe is sleeved on the lower mold, further improving the efficiency of cooling and shaping. In conjunction with a motor, a rotating rod and a fan blade, air is blown to cool the front and back of the lower mold, thereby improving the efficiency of cooling and shaping in a variety of ways.

[0004] However, the above patent only cools the lower mold, and the cooling effect on the upper mold is limited, resulting in an unbalanced cooling effect on the upper and lower sides of the product, which can easily cause deformation or warping of the product, affecting product quality. In addition, the above patent is not convenient for quickly removing the product from the lower mold after the product is formed, thereby affecting processing efficiency. Utility Model Content

[0005] The utility model aims to provide a mold shaping device for waterproof composite materials which can cool down the upper and lower molds at the same time, improve product quality, and facilitate rapid removal of molded products.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A mold shaping device for waterproof composite materials includes a bottom plate, a bottom plate having a bottom mold installed on its upper surface, a first cooling cavity arranged inside the bottom mold, a water inlet pipe and a water outlet pipe connected to both sides of the bottom of the bottom plate, and the water inlet pipe and the water outlet pipe are connected to the first cooling cavity respectively, and both sides of the outer surface of the bottom mold are connected to first connecting pipes, and the first connecting pipes are connected to the first cooling cavity. A U-shaped bracket is installed on the upper surface of the bottom plate, a hydraulic cylinder is installed on the top of the U-shaped bracket, an upper mold is installed at the end of the telescopic end of the hydraulic cylinder, both sides of the outer surface of the upper mold are connected to second connecting pipes, a second cooling cavity is arranged inside the upper mold, and both second connecting pipes are connected to the second cooling cavity. Two inner grooves are provided inside the lower mold, and two ejector rods are installed inside the inner groove through an ejection mechanism, and the upper ends of the ejector rods penetrate into the molding groove of the lower mold.

[0008] It can be seen that when the upper mold and the lower mold are closed, the first connecting pipe will be connected with the second connecting pipe, so that the first cooling cavity and the second cooling cavity form a connected space. Therefore, cooling water can flow in the first cooling cavity and the second cooling cavity, so as to achieve the purpose of cooling both the lower mold and the upper mold, so that the cooling effect on the upper and lower sides of the product is balanced, thereby avoiding deformation or warping of the product and improving product quality. After the product is finalized, the ejector mechanism can be used to push the ejector rod to lift the product upward from the molding groove of the lower mold, so that the product can be quickly taken out and the processing efficiency can be improved.

[0009] Furthermore, the ejection mechanism includes a horizontal plate arranged inside the inner groove, and two ejector rods are installed on the upper surface of the horizontal plate, both sides of the upper surface of the horizontal plate are connected with pressure rods, the upper ends of the pressure rods pass through the outside of the lower mold, and both sides of the bottom of the horizontal plate are connected with first springs.

[0010] When the upper mold moves downward and closes with the lower mold, the upper mold will squeeze the pressure rod to make it shrink downward, and drive the cross plate to compress the first spring. When the product is finalized, the upper mold moves upward. At this time, the compressed first spring releases its elastic force, so it can push the ejector rod to lift the product upward, which is convenient for quick demoulding.

[0011] Furthermore, a solenoid valve is installed on the first connecting pipe.

[0012] By setting the solenoid valve, it is convenient to control the on-off state of the first connecting pipe, and the cooling water always circulates in the first cooling chamber. When the first connecting pipe is connected to the second connecting pipe, the solenoid valve controls the opening of the first connecting pipe, so that the cooling water can flow in the second cooling chamber.

[0013] Furthermore, a connecting end is installed at the end of the upper mold, a sealing plug is provided inside the connecting end, a second spring is provided inside the connecting end, and both ends of the second spring are respectively connected to the sealing plug and the top wall of the connecting end, and a ejector pin is installed inside the first connecting tube, and the upper end of the ejector pin extends to the outside of the first connecting tube.

[0014] When the upper mold descends, the end of the first connecting tube is inserted into the connecting end head, and the ejector pin pushes the sealing plug upward, so that cooling water can flow through the gap between the sealing plug and the inner wall of the connecting end head. When the upper mold rises and drives the first connecting tube to be pulled out from the connecting end head, the sealing plug can re-seal the inside of the connecting end head under the push of the second spring, preventing the cooling water inside the second cooling chamber from flowing out and causing environmental pollution.

[0015] Furthermore, two guide rods are installed inside the inner groove, and both guide rods penetrate the interior of the transverse plate, and two first springs are respectively sleeved on the outer surfaces of the two guide rods.

[0016] By setting the guide rod, the first spring can be guided to avoid bending and deformation, thereby improving the performance.

[0017] Furthermore, a rubber pad is provided on the inner wall of the connecting end, and a sealing plate is sleeved on the outer surface of the first connecting pipe.

[0018] When the end of the first connecting pipe is inserted into the connecting terminal, the rubber pad on the inner wall of the connecting terminal will wrap around the outer surface of the end of the first connecting pipe to play a sealing role, and the upper surface of the sealing plate will press against the lower surface of the connecting terminal, thereby achieving a secondary sealing effect to avoid leakage.

A U-shaped bracket 106 is installed on the upper surface of the bottom plate 100, a hydraulic cylinder 107 is installed on the top of the U-shaped bracket 106, an upper mold 108 is installed at the end of the telescopic end of the hydraulic cylinder 107, the outer surfaces of both sides of the upper mold 108 are connected to the second connecting pipe 109, a second cooling cavity 110 is arranged inside the upper mold 108, and the two second connecting pipes 109 are both connected to the second cooling cavity 110. Two inner grooves 111 are formed inside the lower mold 101 . Two ejector pins 112 are installed inside the inner grooves 111 through an ejection mechanism 200 . The upper ends of the ejector pins 112 penetrate into the molding grooves of the lower mold 101 .

[0027] When in use, the water inlet pipe 103 and the water outlet pipe 104 are first connected to the inlet and outlet ends of the cooling water respectively, and the upper mold 108 is driven by the hydraulic cylinder 107 to move downward and close with the lower mold 101 to complete the mold closing. At this time, the first connecting pipes 105 on both sides of the lower mold 101 are respectively connected and connected with the second connecting pipes 109 on both sides of the upper mold 108, so that the first cooling cavity 102 and the second cooling cavity 110 form a connected space. Therefore, when the cooling water enters the first cooling cavity 102 through the water inlet pipe 103, it will flow through the second cooling cavity 110 and be discharged from the water outlet pipe 104, so that the cooling water circulates in the first cooling cavity 102 and the second cooling cavity 110, so as to achieve the purpose of cooling the lower mold 101 and the upper mold 108, so that the cooling effect on the upper and lower sides of the product is balanced, and the product quality is improved.

When the upper mold 108 descends, the first connecting tube 105 5 is inserted into the connecting terminal 400, and the ejector pin 403 pushes the sealing plug 401 upward, so that the cooling water can flow through the gap between the sealing plug 401 and the inner wall of the connecting terminal 400. When the upper mold 108 rises to drive the first connecting pipe 105 to be drawn out from the connecting terminal 400, the sealing plug 401 can re-seal the inside of the connecting terminal 400 under the push of the second spring 402, so as to prevent the cooling water in the second cooling chamber 110 from flowing out and causing environmental pollution.

[0031] Specifically, two guide rods 500 are installed inside the inner groove 111, and the two guide rods 500 both penetrate the interior of the cross plate 201, and the two first springs 203 are respectively sleeved on the outer surfaces of the two guide rods 500.
