Technical Field

[0001] This invention relates to the field of PC component technology, specifically to an automated injection molding method for PC components. Background Technology

[0002] PC components are concrete products manufactured in factories using standardized and mechanized methods. These components are widely used in construction, transportation, water conservancy, and other fields, and are especially known as PC components in the field of residential industrialization. In contrast, traditional cast-in-place concrete requires on-site molding, pouring, and curing.

[0003] A search revealed a Chinese patent (publication number: CN112622023B) that discloses a method for forming and manufacturing precast reinforced concrete components. This patent uses a precast reinforced concrete component forming device, which includes a base plate, a columnar mold, and a heating and drying device. The columnar mold is evenly installed in the middle of the upper surface of the base plate, and the heating and drying device is installed inside the columnar mold by means of rotational engagement. The heating and drying device is installed on the base plate.

[0004] In the existing technology, the production efficiency of PC components in mass production is slow, and a large number of workers are required to cooperate during demolding and injection. Therefore, the present invention proposes an automated injection molding method for PC components. Summary of the Invention

[0005] The purpose of this invention is to provide an automated injection molding method for PC components.

[0006] The technical problem solved by this invention is: how to improve the efficiency of mass production of PC components, and how to reduce the labor intensity of workers during production.

[0007] This invention can be achieved through the following technical solution: an automated injection molding method for PC components, the method comprising the following steps:

[0008] Step 1: Based on the PC component to be produced, make a molding mold of the corresponding shape and tie the corresponding steel reinforcement frame;

[0009] Step 2: Place multiple forming molds onto the forming platform in the forming equipment. The forming platform will fix the forming molds. Then, place the corresponding steel bar frames into each forming mold.

[0010] Step 3: Pour premixed concrete into each molding mold and vibrate it to compact the concrete in each molding mold.

[0011] Step 4: Move each molding die to the protective box of the molding equipment for curing, and mold to obtain PC components;

[0012] Step 5: After the PC components in each molding die have reached the design standard, remove each molding die from the curing box and disassemble each molding die by disassembling the components.

[0013] A further technical improvement of the present invention is that the molding equipment includes a curing box and multiple slide rail components. When in use, the curing box is placed on the ground, and the multiple slide rail components are buried in the ground and extend from the outside into the interior of the curing box. A molding table is installed at the output end of each slide rail component.

[0014] The forming table moves between the inside and outside of the curing chamber based on various slide rail components;

[0015] Each molding die is placed on the molding platform and fixed based on the molding platform during use.

[0016] A further technical improvement of the present invention is that: a fixed frame is provided on the upper side of each slide rail component, and the splitting component is connected to the output end of the fixed frame. After the forming table drives each forming mold to move to the lower side of the fixed frame, the splitting component moves to the upper side of each forming mold in sequence to disassemble the corresponding forming mold.

[0017] A further technical improvement of the present invention is that the molding die includes a first module plate and a second module plate;

[0018] Multiple connecting posts are installed at both ends of the first module board facing the second module board;

[0019] The second module board has multiple connecting slots at both ends facing the first module board, and each connecting slot matches a connecting post.

[0020] After the first module plate and the second module plate are assembled, each connecting column is embedded into the corresponding connecting groove, and the area between the first module plate and the second module plate forms a PC component shaping area. When placing the steel reinforcement frame, it is placed in the corresponding PC component shaping area.

[0021] A further technical improvement of the present invention is that: a first side plate is installed on both sides of the first module board, and the two sets of first side plates have the same height;

[0022] The second module board has a second side plate installed on both sides, and the two sets of second side plates are at the same height.

[0023] The two sets of first side panels and the two sets of second side panels are staggered, meaning that the heights of the two sets of first side panels and the two sets of second side panels are not the same.

[0024] A further technical improvement of the present invention is that: the forming table includes a base plate connected to each slide rail component, and upright plates are installed on both sides of the upper surface of the base plate;

[0025] Multiple second-stroke mechanisms are installed on opposite sides of both sets of vertical plates;

[0026] After each molding die is placed on the upper side of the substrate, the second stroke mechanism on the corresponding side of each molding die is activated to fix the first module plate and the second module plate in the molding die.

[0027] A further technical improvement of the present invention is that: multiple heating elements are installed inside the curing box, and when the molding mold is located inside the curing box, each heating element is activated to heat the PC component.

[0028] A further technical improvement of the present invention is that: the multiple heating elements are divided into a first heating group and a second heating group. The first heating group is installed on both sides inside the curing box, and the second heating group is installed horizontally at the bottom of the curing box and located on one side of each slide rail component. At the same time, the heat source of each heating element in the second heating group is set upward.

[0029] The curing box is equipped with a water spray assembly located on the upper side of each heating element of the second heating group. The water inlet of the water spray assembly is equipped with a water inlet pipe extending to the outside of the curing box.

[0030] The inlet pipe is equipped with a valve to control the connection between the inlet pipe and the water spray assembly.

[0031] A further technical improvement of the present invention is that: the water outlet of the water spraying component is equipped with a vibration component, which turns the water into small water droplets when the water flows through, and causes them to disperse and drip onto each heating element of the second heating group, thereby accelerating the efficiency of each heating element in the second heating group in turning the water into water vapor.

[0032] A further technical improvement of the present invention is that: the curing box is equipped with a blower mechanism on the side of the second heating group facing away from the slide rail. The blower mechanism includes an output component and a heating component. The output component passes air through the heating component, heats it, and then discharges it, blowing the steam generated by the second heating group toward each molding die.

[0033] A further technical improvement of the present invention is that the splitting component includes a third stroke mechanism and two sets of sliding frames;

[0034] The third stroke mechanism is connected to the output end of the fixed frame, and the output end of the third stroke mechanism faces downward and is equipped with a connecting plate. Sliding clamping plates are slidably connected to both sides of the connecting plate.

[0035] The two sets of sliding frames are slidably connected to each other, and a connecting groove is provided between the two sets of sliding frames;

[0036] Multiple locking components with through-slide grooves are installed between the two sets of sliding clamping plates;

[0037] The locking component includes a screw section and a nut section. The screw section passes through the first set of sliding clamping plates, the slide groove, and the second set of sliding clamping plates in sequence. The nut section is screwed to one end of the screw section to clamp the two sets of sliding clamping plates and fix the two sets of sliding frames inside the two sets of sliding clamping plates.

[0038] Both ends of the two sets of sliding frames are equipped with extension frames, and the extension frames and the corresponding sliding frames are distributed in a T-shape.

[0039] Both ends of the two sets of sliding frames are equipped with a fourth stroke mechanism via connecting rods;

[0040] The heights of the two sets of fourth-stroke mechanisms are the same as the heights of the first or second side plates in the corresponding molding die in the opposite direction.

[0041] That is, when the fourth stroke mechanism is on the same side as the first side plate in the forming mold, its height is the same as the height of the second side plate;

[0042] When the fourth stroke mechanism is on the same side as the second side plate in the forming mold, its height is the same as the height of the first side plate;

[0043] After the fourth stroke mechanism at both ends of the two sets of extension frames moves to the upper side of the forming mold, the four sets are at the same height as the two sets of first side plates and the two sets of second side plates respectively, and with the movement of each fourth stroke mechanism, the first module plate and the second module plate in the forming mold are unfolded.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] In the production of PC components, the present invention fixes a molding mold based on the shape of the PC component in a molding table, and after pouring concrete, moves it to a curing box for curing. During curing, the PC component can be heated inside the curing box, which can improve the molding quality of the PC component. Furthermore, the production process is highly automated and mechanized, which can reduce the labor intensity of workers.

[0046] On the other hand, after the PC component is hooked, each molding die can be moved to the lower side of the fixed frame and demolded by disassembling the components, which makes it easy to separate the PC component from the molding die. When producing a batch of PC components, the demolding efficiency is high and the number of workers required can be reduced. Attached Figure Description

[0054] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0055] Please see Figure 1-5 As shown, an automated injection molding method for PC components includes the following steps:

[0056] Step 1: Based on the PC component to be produced, make a molding mold 4 of the corresponding shape and tie the corresponding steel reinforcement frame;

[0057] Step 2: Place multiple forming molds 4 onto the forming table 3 in the forming equipment. The forming table 3 fixes the forming molds 4. Then, place the corresponding steel bar frames into each forming mold 4.

[0058] Step 3: Pour premixed concrete into each molding mold 4 and vibrate it to compact the concrete in each molding mold 4.

[0059] Step 4: Move each molding die 4 to the curing box 1 of the molding equipment for curing to obtain PC components;

[0060] Step 5: After the strength of the PC components in each molding mold 4 reaches the design standard, remove each molding mold 4 from the curing box 1 and disassemble each molding mold 4 by using the disassembly component 6.

[0061] The molding equipment includes a curing box 1 and multiple slide rail components 2. When in use, the curing box 1 is placed on the ground. When in use, the multiple slide rail components 2 are buried in the ground and extend from the outside into the interior of the curing box 1. A molding table 3 is installed at the output end of each slide rail component 2.

[0062] The molding table 3 moves between the inside and outside of the curing box 1 based on the various slide rail components 2;

[0063] Each molding die 4 is placed on the molding platform 3 and fixed based on the molding platform 3 during use.

[0064] Each slide rail 2 is provided with a fixed frame 5 on its upper side. The splitting component 6 is connected to the output end of the fixed frame 5. After the forming table 3 drives each forming mold 4 to move to the lower side of the fixed frame 5, the splitting component 6 moves to the upper side of each forming mold 4 in sequence to disassemble the corresponding forming mold 4.

[0065] Furthermore, the curing box 1 has an opening on the side facing the fixed frame 5, and lifting cylinders are installed on both sides of the curing box 1. A sealing door is slidably connected inside the opening. The output ends of the two sets of lifting cylinders are connected to the sealing door. When heating curing is required, the two sets of lifting cylinders drive the sealing door to block the opening.

[0066] Please see Figure 3 As shown, the molding die 4 includes a first module plate 41 and a second module plate 42;

[0067] Multiple connecting posts 44 are installed at both ends of the first module plate 41 facing the second module plate 42;

[0068] The second module plate 42 has multiple connecting slots 43 at both ends facing the first module plate 41, and each connecting slot 43 is matched with each connecting post 44.

[0069] After the first module plate 41 and the second module plate 42 are assembled, each connecting column 44 is embedded into the corresponding connecting groove 43, and the area between the first module plate 41 and the second module plate 42 forms a PC component shaping area. When the steel reinforcement frame is placed, it is placed in the corresponding PC component shaping area.

[0070] Both sides of the first module plate 41 are equipped with first side plates 45, and the two sets of first side plates 45 are at the same height.

[0071] The second module plate 42 has a second side plate 46 installed on both sides, and the two sets of second side plates 46 have the same height.

[0072] The two sets of first side plates 45 and the two sets of second side plates 46 are staggered, meaning that the heights of the two sets of first side plates 45 and the two sets of second side plates 46 are not the same.

[0073] Please see Figure 2 , Figure 4 As shown, the forming table 3 includes a base plate 31 connected to each slide rail 2, and upright plates 32 are installed on both sides of the upper surface of the base plate 31.

[0074] Multiple second-stroke mechanisms 33 are installed on one side of each of the two sets of upright plates 32;

[0075] After each molding die 4 is placed on the upper side of the substrate 31, the second stroke mechanism 33 of each molding die 4 on the corresponding side is activated to fix the first module plate 41 and the second module plate 42 in the molding die 4.

[0076] Multiple heating elements 7 are installed inside the curing chamber 1. When the molding die 4 is inside the curing chamber 1, each heating element 7 is activated to heat the PC component.

[0077] The multiple heating elements 7 are divided into a first heating group and a second heating group. The first heating group is installed on both sides inside the curing box 1, and the second heating group is installed horizontally at the bottom of the curing box 1 and located on one side of each slide rail 2. At the same time, the heat source of each heating element 7 in the second heating group is set upward.

[0078] The curing box 1 is equipped with a water spray assembly 8 located on the upper side of each heating element 7 of the second heating group. The water inlet of the water spray assembly 8 is equipped with a water inlet pipe 9 extending to the outside of the curing box 1.

[0079] A valve is installed inside the water inlet pipe 9 to control the connection between the water inlet pipe 9 and the water spray assembly 8.

[0080] The water outlet of the water spray assembly 8 is equipped with a vibration component, which turns the water into small water droplets as it flows through, causing them to disperse and drip onto each heating element 7 of the second heating group, thereby accelerating the efficiency of each heating element 7 in the second heating group in turning the water into water vapor.

[0081] The curing box 1 is equipped with a blower mechanism 10 on the side of the second heating group facing away from the slide rail 2. The blower mechanism 10 includes an output component and a heating component. The output component passes air through the heating component, heats it, and then discharges it, blowing the steam generated by the second heating group toward each molding die 4.

[0082] The side of the maintenance box 1 has a connecting port 11, and a plurality of first-stroke cylinders 12 are installed inside the maintenance box 1 on one side of the connecting port 11. The output end of each first-stroke cylinder 12 faces the connecting port 11 and is equipped with a sealing plate 13.

[0083] After the first-stroke cylinder 12 attaches the sealing plate 13 to one side of the connecting port 11, it separates the connecting port 11 from the outside.

[0084] Please see Figure 5 As shown, the split component 6 includes a third stroke mechanism 61 and two sets of sliding frames 64;

[0085] The third stroke mechanism 61 is connected to the output end of the fixed frame 5, and the output end of the third stroke mechanism 61 faces downward and is equipped with a connecting plate 62. Both sides of the connecting plate 62 are slidably connected with sliding clamping plates 63.

[0086] In this embodiment, the output end of the fixing frame 5 adopts a lead screw drive mechanism;

[0087] The two sets of sliding frames 64 are slidably connected to each other, and a connecting groove is provided between the two sets of sliding frames 64;

[0088] Multiple locking elements 65 with through-slide grooves are installed between the two sets of sliding clamping plates 63;

[0089] The locking component 65 includes a screw section and a nut section. The screw section passes through the first set of sliding clamping plates 63, the slide groove, and the second set of sliding clamping plates 63 in sequence. The nut section is screwed to one end of the screw section to clamp the two sets of sliding clamping plates 63 and fix the two sets of sliding frames 64 inside the two sets of sliding clamping plates 63.

[0090] Both ends of the two sets of sliding frames 64 are equipped with extension frames 66, and the extension frames 66 and the corresponding sliding frames 64 are distributed in a T-shape.

[0091] Both ends of the two sets of sliding frames 64 are equipped with a fourth stroke mechanism 68 via a connecting rod 67;

[0092] The heights of the two sets of fourth stroke mechanisms 68 are the same as the heights of the first side plate 45 or the second side plate 46 in the corresponding forming mold 4 in the opposite direction.

[0093] That is, when the fourth stroke mechanism 68 is on the same side as the first side plate 45 in the forming mold 4, its height is the same as the height of the second side plate 46;

[0094] When the fourth stroke mechanism 68 is on the same side as the second side plate 46 in the forming mold 4, its height is the same as the height of the first side plate 45.

[0095] After the fourth stroke mechanisms 68 at both ends of the two sets of extension frames 66 move to the upper side of the forming mold 4, the four sets of fourth stroke mechanisms 68 are at the same height as the two sets of first side plates 45 and the two sets of second side plates 46 respectively, and with the movement of each fourth stroke mechanism 68, the first module plate 41 and the second module plate 42 in the forming mold 4 are unfolded.

[0096] When using this invention, the first module plate 41 and the second module plate 42 in the molding mold 4 are assembled and placed on the upper side of the molding table 3. The second stroke mechanism 33 at the corresponding positions on both sides of the molding mold 4 is activated to fix the first module plate 41 and the second module plate 42 on the upper side of the molding table 3.

[0097] After fixing each molding mold 4 onto the molding platform 3, pour concrete into each molding mold 4 and vibrate each molding mold 4.

[0098] When heating and curing are required, each slide rail component 2 is activated, moving the forming table 3 into the curing chamber 1. Then the sealing door is closed, and each heating component 7 is activated to heat the interior space of the curing chamber 1.

[0099] Furthermore, when steam curing is required, water is injected into the water spraying assembly 8 from the water inlet pipe 9. The water spraying assembly 8 disperses the water into water droplets, which then drip onto each heating element 7 in the second heating group. When the heat source of each heating element 7 in the second heating group comes into contact with the water droplets, it vaporizes them to form water vapor. At the same time, the blower mechanism 10 is activated to blow the vaporized water vapor toward each molding mold 4.

[0100] After curing and molding, each slide rail component 2 moves the molding table 3 from the curing box 1 to the lower side of the fixed frame 5. Each disassembly component 6 is adjusted based on the shape of the molding mold 4, and the length of the two sets of slide frames 64 is changed.

[0101] After the fixed frame 5 moves the splitting assembly 6 to the upper side of a set of forming molds 4, the third stroke mechanism 61 lowers each fourth stroke mechanism 68 to one side of the forming mold 4 corresponding to the first side plate 45 and the second side plate 46. Then each fourth stroke mechanism 68 is activated to disassemble the corresponding forming mold 4.

[0102] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
