Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an integrated EPP toolbox and its mold. Background Technology

[0002] Traditional cars typically have a spare tire compartment and a luggage compartment in the trunk, separated by a trunk carpet. The spare tire compartment stores the spare tire and driving tools. However, with the development of new energy vehicles and based on the layout, installation, and lightweight requirements of new energy batteries, new energy vehicles usually do not have a spare tire compartment and do not provide spare tire storage. For daily driving and emergency needs, they are equipped with smaller and lighter items such as trailer hitches, air pumps, tire sealant, warning triangles, portable chargers, external power outlets, reflective vests, and tire lug nuts clips. In addition, depending on the user's needs, they may also be equipped with umbrellas, air pillows, dedicated air mattresses, camping equipment, and other supplies. To meet the original layout of the spare tire compartment, the load-bearing capacity, sound insulation, and protection of the trunk carpet, and the storage of driving emergency supplies and other driving supplies, a toolbox that can simultaneously meet the above requirements needs needs to be designed. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated EPP toolbox and its mold to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: an integrated EPP toolbox, comprising a toolbox body, wherein a segmented cover is provided on the toolbox body, and a pull strap is provided on the segmented cover; the toolbox body includes an inner storage compartment with a large surface area and shallow depth, located on the inner side of the toolbox body; an outer storage compartment with a small surface area and deep depth, located on the side of the toolbox body away from the inner side; and a middle storage compartment with a small surface area and shallow depth, located in the middle region of the toolbox body; a long strip-shaped first reinforcing rib is provided on the back of the inner storage compartment, and a short strip-shaped second reinforcing rib is provided on the back of the outer storage compartment.

Both are for increasing the support strength of the box body's sides. Mounting and fixing through holes 36 are provided at the four corners of the bottom surface of the tool box body 1 for fixing the box body. A mounting positioning hole and an adjustable oval mounting hole are provided in the center.

[0034] Furthermore, a triangular warning sign storage space 6 is provided on the side of the toolbox 1, and a retaining rib 7 is provided at the top of the storage space to hold the triangular warning sign in place. The triangular warning sign is placed on the side and held in place by the retaining rib 7 to prevent it from falling out.

[0035] Furthermore, the toolbox 1 is provided with a tire lug nut clip storage space 8, an external power outlet storage space 9, and a trailer hook storage space 10 on its side. This maximizes the use of available space on the side to store more items.

[0036] The toolbox body 1 is made of 30P EPP particles. Its molding process is as follows:

[0037] 1. EPP particle preloading;

[0038] 2. After pre-compression, start the molding equipment to begin molding. The pre-compressed 30P EPP particles are injected into the molding die through back pressure feeding.

[0039] 3. High-temperature steam is introduced for molding, and cooling water is sprayed on after thermoforming;

[0040] 4. Remove the products from the mold and place them in the drying room for baking and shaping.

[0041] Its molding process parameters:

[0042] Steam temperature: 190-220 degrees Celsius; pressure: 8-9 MPa.

[0043] Steam time for mold 16: 20±3s;

[0044] Steam transfer time: 15±3s;

[0045] Cooling water time for mold 16: 110±5s;

[0046] Cooling water transfer time: 110±5s.

[0047] This application also provides a mold for producing an integrated EPP toolbox, including a fixed mold 16 and a moving mold 17, both of which are provided with lifting eye holes 37 for installation, lifting, assembly, etc.

[0048] In the embodiments of this utility model application, please refer to Figure 4 The fixed mold 16 includes a fixed mold frame 18, a water channel 19, a baffle 20, a fixing plate 21, a guide post 22, a mold core 23, and a fixed mold cavity 24.

[0049] In the embodiments of this utility model application, please refer to Figure 10 The water channel 19 of the fixed mold 16 is equipped with cooling water nozzles 42, which are set at different heights according to the shape and height of the mold cavity, so as to spray the water onto the mold cavity more evenly and achieve uniform and rapid cooling.

[0050] In the embodiments of this utility model application, please refer to Figure 5 The moving mold 17 includes a moving mold frame 25, a support column 26, a stop bar 27, an ejector rod 28, a material gun 29, a material gun fixing plate 30, a pad plate 31, and a moving mold cavity 32.

[0051] In the embodiments of this utility model application, please refer to Figure 6 The moving mold cavity 32 includes a vapor plug 33. The vapor plug is made of aluminum alloy and has evenly distributed steam holes on its body. High-temperature steam enters the mold cavity from the steam frame and then heats and shapes the EPP particles inside the mold cavity. It should be noted that the fixed mold cavity 24 also has this vapor plug 33.

[0052] In the embodiments of this utility model application, please refer to Figure 7 The feed gun 29 includes an auxiliary push rod 34. The auxiliary push rod 34 is fixed by a fixing nut 40 for better feeding.

[0053] In the embodiments of this utility model application, please refer to Figure 8 The top rod 28 includes a fixing bolt 35. The fixing bolt 35 serves to position the top rod 28. A high-pressure air inlet 41 is provided on the bottom surface of the top rod 28.

[0054] In the embodiments of this utility model application, the working principle of the mold is as follows: The mold consists of a fixed mold 16 and a moving mold 17. The fixed mold 16 and the moving mold 17 are respectively composed of a steam frame (mold frame) and a mold cavity, etc. The fixed mold steam frame (fixed mold frame 18) is small in height, and the moving mold steam frame (moving mold frame 25) is large in height. Both the fixed mold frame 18 and the moving mold frame 25 are connected to high-temperature steam inlets for air intake 38. The cooling water inlet enters from the fixed mold 16 and exits from the moving mold 17. The high-temperature steam enters from the steam frame (mold frame), then enters the steam pipeline, and then is sprayed out from the steam nozzles evenly distributed on the mold cavity to treat the EPP particles in the mold cavity. After heating and molding, cooling water is injected into the water inlet 39 of the fixed mold steam frame (fixed mold frame 18), filling the fixed mold 16 and moving mold 17, and then discharged from the moving mold frame 25 to cool the molded product. The material gun 29 and ejector pin 28 are evenly distributed on the back of the moving mold cavity. During molding, EPP particles are injected into the mold cavity from the material gun 29 under high pressure, and then back pressure is applied. After the product is molded and cooled, the mold is opened, and the ejector pin 28 is ejected to assist in demolding. To further assist in demolding, the material gun 29 adopts an ejector pin type material gun. When the external ejector pin is ejected, the ejector pin 28 in the material gun 29 is also started to eject synchronously.

[0055] The beneficial effects of this utility model are as follows: This novel toolbox features various storage compartments suitable for storing common automotive supplies of different shapes and sizes. It is an integrated EPP toolbox, molded from 30P EPP particles. It fulfills the requirements of new energy vehicle layouts, including spare tire cover and trunk support, vehicle sound insulation and protection, and categorized storage of driving tools. It is lightweight overall, and the addition of reinforcing ribs improves its load-bearing capacity. Tool storage is rationally categorized, and storage space is ample. Furthermore, it features a simple design, reasonable structure, easy operation, and strong practicality. It replaces the original spare tire and tool storage box, achieving the overall layout and tool storage needs of new energy vehicles without a spare tire compartment, meeting the requirements of lightweight, sound insulation, load-bearing capacity, and rational tool storage.
