Description

Technical Field

[0001] The present invention relates to a foaming mold for a heat preservation board used in a water purifier, and more particularly to a working method of a multi-layer simultaneous foaming mold that can achieve multi-layer foaming and improve work efficiency. Background Art

[0002] Water purifiers for purification are equipped in many current residential communities. It can filter and purify tap water to obtain safer and healthier drinking water.

[0003] During the manufacturing process of such water purifiers, it is necessary to set a heat preservation board inside the housing structure. Especially in the northern regions of China, due to the low temperature, the absence of a heat preservation board will easily cause the freezing of water and the blockage of pipelines. For the manufacturing process of these heat preservation boards, one of the most commonly used processes is to complete it through the injection process of foaming materials, that is, injecting the foaming materials into the mold, closing and pressing, and after it is formed and cooled, a heat preservation board in a block or plate state structure can be obtained. After these heat preservation boards are taken out, they can be applied to the equipment.

[0004] In the traditional injection mold for heat preservation boards, it is usually a single-layer or independent foaming method. Such a working efficiency is low. It is necessary to place multiple foaming units independently, without good centralized storage, and there is no good connection and cooperation relationship between them. And for each foaming unit, fixing and pressing and opening the mold separately will inevitably waste space resources and equipment resources. Summary of the Invention

[0005] The main object of the present invention is to provide a working method of a multi-layer simultaneous foaming mold.

[0006] To achieve the above object, the present invention provides a multi-layer simultaneous foaming mold, which includes a frame structure and a cover structure. The cover structure is arranged at the top position of the frame structure, and the cover structure is detachably connected and fixed to the frame structure. The frame structure has multiple continuously arranged foaming units inside. The foaming unit includes a foaming tank body and a top pressing plate. The top pressing plate is arranged on the upper side of the foaming tank body. Multiple foaming units are stacked in sequence in the vertical direction, and the top pressing plate of the foaming unit located at the top position contacts and abuts against the bottom of the top pressing plate.

[0007] The beneficial effects of the above solution are as follows: With this structure, multiple foaming units can be placed at one time, and then pressed through the cover structure at the top position. Then, the multiple foaming units are stacked and placed in sequence, so that the space can be effectively utilized. Then, the foaming material is injected into the multi-layer foaming units in sequence. After waiting for them to be formed, these foaming units can be quickly taken out and taken out in sequence, improving the work efficiency.

[0008] A preferred solution is that the frame structure includes a first side frame and a second side frame arranged opposite to each other. The first side frame has three first support rods, a first top plate, and a first bottom plate arranged in parallel. The second side frame has three second support rods, a second top plate, and a second bottom plate arranged in parallel. The first bottom plate at the bottom of the first side frame is hinged to the support table through a first hinge. The second bottom plate at the bottom of the second side frame is hinged to the support table through a second hinge. The bottom of the support table has moving rollers.

[0009] The first side of the cover structure is hinged to the first top plate of the first side frame through a top hinge. The second side of the cover structure has a clamping ring body, and there is a clamping member on the second side frame. The clamping member is detachably and separably matched with the search clamping ring body.

[0010] A preferred solution is that it further includes a foaming injection assembly. The foaming injection assembly includes a feeding hose, a fixed track, and a sliding member. The sliding member is slidably arranged on the fixed track. The fixed track is vertically arranged. The upper end and the lower end of the fixed track are respectively connected to the frame structure. The fixed track has spaced-apart insertion holes. The side part of the foaming tank body has injection holes, and the injection holes are correspondingly arranged with the insertion holes. And the sliding member has an insertion tube and a pressing spring. The pressing spring is connected to the insertion tube. The pressing spring and the insertion tube are arranged in the horizontal direction. One side of the insertion tube is connected to the feeding hose, and the other end of the insertion tube is used for inserting into the insertion hole and the injection hole.

[0011] With this structure, the process of quickly injecting the foaming material into multiple foaming units at different height positions can be realized. And during the sliding process, whenever it moves to the insertion hole position at a certain height, the pressing spring automatically drives the insertion tube to move into the insertion hole and the injection hole, thus realizing the functions of automatic insertion and automatic fixation. That is, the process of manually holding this assembly is saved. That is, through the fixing effect of the insertion tube in the insertion hole, the purpose of temporarily fixing and injecting the foaming material is achieved. And the injection position is accurate and precise, avoiding the problems of inaccurate positioning and waste during the injection process.

[0012] In a preferred embodiment, the sliding member further includes a clamping and sliding portion which is slidably fitted on the fixed track. The sliding member includes a receiving frame body which has two side plates and a rear plate. The inner wall of the rear plate is connected to the pressing spring, and the feeding hose passes through the rear plate and is communicated with the insertion tube.

[0013] The sliding member further includes a locking structure which includes an upper locking rod, a lifting frame, a locking block, a driving block and a return spring. The lifting frame is slidably arranged on the side plate. The top of the lifting frame has the locking rod. The bottom of the locking block is connected to the insertion tube. The top of the locking block has a locking groove and a first inclined surface structure. The driving block has a second inclined surface structure. The driving block is located at the top position of the fixed track. The bottom of the return spring is connected to the bottom plate of the lifting frame, and the top of the return spring is connected to the bottom of the rear plate.

[0014] During the upward movement, every time it moves to a jack, the insertion tube is driven by the pressing spring to enter the jack. When the insertion tube comes out of the jack, it also drives the locking groove to move towards the locking rod, but there is still a certain distance between the locking groove and the locking rod, that is, the two do not form a clamping relationship. Until the lifting frame is at the top position, through the contact and cooperation of the first inclined surface structure and the second inclined surface structure, the insertion tube moves further in the reverse direction, that is, the locking groove abuts against the locking rod and the two form a clamping fit, and is pressed and clamped by the downward pressure of the return spring at the bottom. In addition, when moving to the bottom position, the lifting frame and the locking rod rise to a certain extent by contacting the brake plate at the bottom of the lifting frame body, so that the locking rod and the locking groove lose the cooperation relationship, and the pressing spring quickly drives the insertion tube to reset, that is, it can insert into the jack again.

[0015] In a preferred embodiment, the clamping and sliding portion is matched with the fixed track through a roller, and the roller is connected to a driving motor.

[0016] The working method of the foam mold for multi-layer simultaneous foaming provided by the present invention includes the following steps:

[0017] Place the empty foam units one by one into the frame structure, and keep them stacked and pressed against each other. Connect and fix the cover structure at the top position to the frame structure. The cover structure presses the foam unit at the top position, and then presses and fixes the entire foam unit.

[0018] Then, the foamed materials are successively added into the injection holes on the side of the foaming tank of the foaming unit one by one. After the injection of the foaming materials is completed, wait for the foaming and forming to be completed. After forming, open the cover structure, and take out the foaming units inside the frame structure one by one to obtain the foamed plates inside the foaming tank.

[0019] The working method of the foaming mold for multi-layer simultaneous foaming provided by the present invention includes the following steps: The foaming injection assembly successively completes the process of injecting foaming materials into the foaming units at different positions from bottom to top, driving the sliding member to move along the fixed track. Whenever it moves to the jack position, it exactly corresponds to the injection holes of the foaming tanks of a group of the foaming units. At this time, due to the existence of the pressing spring, the cannula is automatically driven to move towards the jack direction. Then, the jack enters into the jack and the injection hole, and then the foaming material enters the cannula along the feeding hose, and then enters the injection hole and then into the foaming tank to carry out foaming; in addition, whenever the injection of materials for one layer of foaming units is completed, the slideway member is pushed to move, and then the cannula is forced to push the pressing spring to move and contract in the reverse direction, so that the cannula leaves the injection hole and the jack, and then continues to move along the fixed track, and then injects materials into the next jack and foaming unit at the position of the previous height.

[0020] The working method of the foaming mold for multi-layer simultaneous foaming provided by the present invention includes the following steps: When the sliding member moves to the top position, the locking structure enters the locked state, and when the sliding member moves to the bottom position, the locking structure enters the separated state; specifically, when the sliding member moves to the top position, the first inclined surface structure contacts the second inclined surface structure, thereby causing the locking block to move away from the fixed track, and then driving the cannula to move away. Until the locking groove on the locking block is engaged and connected with the locking rod, the return spring presses the lifting frame and the locking rod downward. At this time, the cannula is in a fixed state. When the sliding member moves downward, the cannula will not be inserted into the jack due to the action of the locking structure; when the sliding member moves to the bottom position, since the lifting frame will contact the braking plate at the bottom, the lifting frame will move upward, thereby driving the locking rod to lose the engagement relationship with the locking groove. At this time, the cannula can be inserted and matched with the jack again. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Then, add the foaming-formed material into the injection holes 33 on the side of the foaming tank body 31 of the foaming unit 30 one by one. After the foaming material is injected, wait for the foaming and forming to be completed. After forming, open the cover structure 20, and take out the foaming units 30 inside the frame structure 10 one by one to obtain the foamed plate bodies inside the foaming tank body 31.

The sliding member 43 can be manually driven to move along the fixed track 42. Whenever it moves to the position of the insertion hole 44, it just corresponds to the injection hole 33 of the foam tank body 31 of a group of the foam units 30. At this time, due to the existence of the pressing spring 46, the insertion tube 45 is automatically driven to move in the direction of the insertion hole 44. Then the insertion tube 45 enters the insertion hole 44 and the injection hole 33. Then the foam material enters the insertion tube 45 along the feeding hose 41, and then enters the injection hole 33 and then enters the foam tank body 31 for foaming. In addition, whenever the injection of materials for one layer of the foam unit 30 is completed, the sliding member 43 is pushed to move. Then the insertion tube 45 is forced to push the pressing spring 46 to move and contract, so that the insertion tube 45 leaves the injection hole 33 and the insertion hole 44, and then continues to move along the fixed track 42, and then injects materials into the next insertion hole 44 and the foam unit 30 at the previous height position.

[0042] The third embodiment:

[0043] As Figures 4 to 9 shown, the sliding member 43 further includes a clamping and sliding portion 50. The clamping and sliding portion 50 is slidably fitted on the fixed track 42. The sliding member 43 includes a receiving frame body 52. The receiving frame body 52 has two side plates 53 and a rear plate 54. The inner wall of the rear plate 54 is connected to the pressing spring 46, and the feeding hose 41 passes through the rear plate 54 and is communicated with the insertion tube 45.

[0046] The working method of the foaming mold for multi-layer simultaneous foaming provided by the present invention includes the following steps: when the sliding member 43 moves to the top position, the locking structure 60 enters the locking state, and when the sliding member 43 moves to the bottom position, the locking structure 60 enters the separated state; specifically, when the sliding member 43 moves to the top position, the first inclined surface structure 67 contacts the second inclined surface structure 68, so that the locking block 63 moves away from the fixed track 42, and then drives the insertion tube 45 to move away until the locking groove 66 on the locking block 63 is engaged and connected with the locking rod 61. The return spring 65 presses the lifting frame 62 and the locking rod 61 downward. At this time, the insertion tube 45 is in a fixed state, and when the sliding member 43 moves downward, the insertion tube 45 will not be inserted into the insertion hole 44 due to the action of the locking structure 60; when the sliding member 43 moves to the bottom position, since the lifting frame 62 contacts the bottom brake plate 72, the lifting frame 62 is lifted, so that the locking rod 61 loses the engagement relationship with the locking groove 66, and the pressing spring 46 then drives the insertion tube to move in the direction of the fixed track. At this time, the insertion tube 45 can be inserted and matched with the insertion hole 44 again.
