Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic insulation molding and processing technology, specifically a rubber and plastic insulation material molding machine. Background Technology

[0002] Rubber and plastic insulation materials use rubber and plastic (such as nitrile rubber and plastic) and polyvinyl chloride (PVC) as core raw materials. They are made into closed-cell foam structure through processes such as mixing, internal mixing, continuous extrusion, heating and foaming, and cooling and slitting. This structure gives the material excellent thermal insulation performance. At the same time, due to the high closed-cell rate (up to 90% or more), the water vapor permeation resistance is strong, and there is no need to add an additional vapor barrier layer. Rubber and plastic insulation materials need to be molded during production, so molding machines are required.

[0003] The "Insulation Material Molding Machine" disclosed in publication number "CN212708107U" includes a worktable and a clamping seat. A lower support is fixedly connected to the lower end of the worktable, an upper support is fixedly connected to the upper end of the worktable, a container is fixedly connected to the upper end of the lower support, an outer barrel is placed inside the container, an insulation barrel is placed inside the outer barrel, an end cap is clamped to the upper end of the outer barrel, and threaded sleeves are evenly fixedly connected to the upper end of the worktable. Threaded sleeves are connected to threaded rods through threaded rotation.

[0004] Traditional molding machines do not have the function of preheating recovery during operation, which leads to the loss and waste of heat energy during operation. A large amount of heat energy is directly wasted, resulting in high electricity or fuel costs and directly increasing production costs. To address this issue, we have designed a rubber and plastic insulation material molding machine. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 scope of protection of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-5 As shown, this embodiment proposes a rubber and plastic insulation material molding machine, including a support frame 1 and a movable frame 5 assembled on the front of the support frame 1. A molding mold 2 is fixedly installed on the front of the support frame 1. A molding cavity 201 is opened on the top of the molding mold 2. A first heating rod 203 is fixedly installed in the lower part of the interior of the molding mold 2. A top plate 101 is fixedly installed on the top of the support frame 1. A hydraulic cylinder 4 is fixedly installed on the top of the top plate 101. A mold base 301 is fixedly installed at the output end of the hydraulic cylinder 4. An extrusion mold 3 is fixedly installed at the bottom of the mold base 301. A second heating rod 303 is fixedly installed in the lower part of the interior of the extrusion mold 3. A base 102 is fixedly installed at the bottom of the support frame 1. The movable frame 5 is fixedly installed in the lower part of the front of the support frame 1. Two sets of preheating boxes 6 are assembled inside the movable frame 5.

[0026] In use, the support frame 1 provides overall support for the molding machine during operation. The rubber and plastic raw material is placed into the molding cavity 201 at the top of the molding die 2. The first heating rod 203 heats the rubber and plastic raw material inside the molding cavity 201. A top plate 101 is fixedly installed on the top of the support frame 1, and a hydraulic cylinder 4 is fixedly installed on the top of the top plate 101. The output end of the hydraulic cylinder 4 passes through the top plate 101 and is fixedly installed with a mold base 301. An extrusion die 3 is fixedly installed at the bottom of the mold base 301. The extrusion die 3 can be lowered by extending the hydraulic cylinder 4, descending into the molding cavity 201. Multiple sets of second heating rods 303 are fixedly installed inside the extrusion die 3, which heats the extrusion die 3, thus heating the extrusion die 3 and the molding cavity 201. Heating and heat-molding the rubber and plastic raw materials enable the processing and molding of rubber and plastic insulation materials. A heat-absorbing plate 204 is fixedly installed at the bottom of the molding mold 2 and is embedded in the bottom of the molding mold 2. The heat-absorbing plate 204 can absorb excess heat during the operation of the molding mold 2. The preheating box 6 can store the rubber and plastic material to be used. When the preheating box 6 is placed under the molding mold 2, the heat-conducting fins 205 at the bottom of the heat-absorbing plate 204 will be inserted into the preheating box 6. Thus, the raw material to be processed can be preheated through the heat-absorbing plate 204 and the heat-conducting fins 205. Preheating can improve the speed and quality of molding the rubber and plastic insulation material by the molding machine and improve the stability of the molding machine. The moving frame 5 is fixedly installed under the front of the support frame 1 and can support the preheating box 6.

[0027] Example 2

[0028] Based on Example 1, such as Figures 1-5 As shown, the movable frame 5 has a sliding groove 501 inside, the preheating box 6 has a sliding plate 601 fixedly installed on the top, the molding mold 2 has a heat absorption plate 204 fixedly installed at the bottom, the heat absorption plate 204 has multiple sets of heat-conducting fins 205 fixedly installed at the bottom, the base 102 has an electric push rod 7 fixedly installed on the top, and the output end of the electric push rod 7 has a bracket 701 fixedly installed.

[0029] In use, the sliding plate 601 mounted on the top of the preheating box 6 is slidably installed in the slide groove 501 on the top of the moving frame 5. The preheating box 6 can be slidably installed through the sliding plate 601 and the slide groove 501. When the preheating box 6 is moved to one side of the molding mold 2, it is convenient for the operator to put the lowered raw material into it. When the preheating box 6 moves to the bottom of the molding mold 2, the electric push rod 7 extends. When the electric push rod 7 extends, it will lift the bracket 701. The lifting of the bracket 701 can lift the preheating box 6 synchronously, so that the top of the preheating box 6 contacts the bottom of the molding mold 2. This facilitates the heat absorption plate 204 and the heat conduction fins 205 to preheat the rubber and plastic raw material inside the preheating box 6. After the rubber and plastic material is preheated, the operator moves the preheating box 6 to the other side of the molding mold 2, which makes it convenient for the operator to take out the preheated rubber and plastic raw material and put it into the molding cavity 201. This increases the functionality of the molding machine and improves the convenience of the operator when handling the preheated rubber and plastic raw material.

[0030] like Figure 5 As shown, limiting angle plates 702 are fixedly installed around the top of the bracket 701.

[0031] When in use, the limiting angle plate 702 can limit the four corners when the bracket 701 supports the bottom of the preheating box 6, thereby ensuring the stability of the bracket 701 when lifting the preheating box 6 and avoiding displacement or tilting during the lifting process of the preheating box 6.

[0032] like Figure 4 As shown, limit rods 202 are fixedly installed around the top of the molding die 2, and limit holes 302 that cooperate with the limit rods 202 are opened around the bottom of the die base 301.

[0033] When in use, the limiting rod 202 will be inserted into the limiting hole 302 when the extrusion die 3 descends. Thus, the path of the extrusion die 3 when it descends into the forming cavity 201 can be limited by the limiting rod 202 and the limiting hole 302, so as to avoid the extrusion die 3 from being misaligned when descending.

[0034] like Figure 4 As shown, a heat insulation plate 304 is fixedly installed on the upper part of the inside of the extrusion die 3.

[0035] When in use, the heat insulation plate 304 can insulate the upper part of the extrusion die 3 to prevent the heat generated by the second heating rod 303 from being transmitted to the upper part, thus avoiding the loss and waste of heat energy.

[0036] like Figures 1-3 As shown, lifting rods 602 are fixedly installed on both sides of the preheating box 6, and grip sleeves 603 are fixedly installed on the outer walls of the lifting rods 602.

[0037] In use, the lifting rod 602 facilitates the lifting and moving of the preheating box 6 by the staff, and the grip sleeve 603 increases the flexibility of the outer wall of the lifting rod 602, improving the comfort of the staff when lifting the preheating box 6.

[0038] like Figure 1 and Figure 2 As shown, the base 102 has fixing grooves 103 on all four sides of its top, and fixing through holes are provided on the fixing grooves 103.

[0039] In use, the fixing groove 103 and the fixing through hole can be used to fix the base 102 with bolts, thereby increasing the firmness of the base 102 when supporting the bottom of the support frame 1 and ensuring the stability of the molding machine during operation.

[0040] Working principle: The combination of molding die 2, first heating rod 203, extrusion die 3, and second heating rod 303 allows for the heating and extrusion molding of rubber and plastic insulation materials. The preheating box 6 stores the rubber and plastic materials to be used. The heat-absorbing plate 204 and heat-conducting fins 205 can recover excess heat during the operation of molding die 2 and conduct it to the interior of the preheating box 6 for preheating the rubber and plastic materials to be used. The moving frame 5 supports the preheating box 6, and the preheating box 6 can be moved inside the moving frame 5 through the cooperation of sliding plate 601 and sliding groove 501. The movement of the preheating box 6 facilitates the placement of rubber and plastic raw materials into the preheating box 6 and the removal of the preheated rubber and plastic raw materials.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
