[0028] The outer template 1 is mainly used for supporting the mold to form the product. The support base 2 not only allows the entire device to be placed stably, but also allows the outer template 1 to be opened and closed;

[0029] The outer formwork 1 comprises a bottom plate 101, side plates 102 hinged to both sides of the bottom plate 101, and end plates 103 hinged to both ends of the bottom plate 101;

[0030] The support base 2 includes a support plate 201, a first threaded rod 202 is rotatably connected to the upper surface of the support plate 201, and two second threaded rods 203 are rotatably connected to the upper surface of the support plate 201, and two connecting blocks 204 are rotatably connected to the lateral sides of the first threaded rod 202 and the second threaded rod 203, and each connecting block 204 is hinged to a connecting plate 205, and one end of the connecting plate 205 away from the connecting block 204 is respectively hinged to the outer surface of the side plate 102 or the end plate 103 at the corresponding position;

[0031] When demoulding, the first motor 2021 is started, and the first motor 2021 rotates to drive the first threaded rod 202 to rotate through the transmission wheel group, and then the two connecting blocks 204 threadedly connected on the first threaded rod 202 move toward the two ends of the first threaded rod 202, and then the end plate 103 is pulled outward through the connecting plate 205 to open, and finally the end plate 103 is opened, and the side plate 102 is also the same, and finally the end plate 103 is opened by pulling the connecting plate 205 connected to the connecting block 204;

[0032] Two vertical poles 206 are fixed on the upper surface of the support base 2, and the same pry bar 207 intersects the two vertical poles 206. A slot is opened on one side of the lower surface of the bottom plate 101, and a pry plate 2071 with a shape and size corresponding to the slot opened on the bottom plate 101 is hinged at one end of the pry bar 207.

[0033] When removing the bottom, one only needs to hold the handle 2072 and apply downward pressure, and then the pry bar 207 will pry the pry plate 2071 under the action of the lever, and finally eject the mold, which greatly increases the convenience of demoulding.

[0034] A top plate 208 is also fixed on the upper surface of the support plate 201 , and a hydraulic telescopic rod 209 is vertically fixed at the center of the top plate 208 .

[0035] The cover plate 104 is fixed to the telescopic end of the hydraulic telescopic rod 209; the hydraulic telescopic rod 209 is mainly used to control the closing of the cover plate 104, so that the material is shaped and finally becomes a finished product.

[0036] The threads at both ends of the first threaded rod 202 and the second threaded rod 203 are mirror-imaged, and the mirror-image setting can realize the mirror-image movement of the connecting block 204, and finally realize the synchronous opening and closing of the end plates 103 or the side plates 102 on both sides.

[0037] The first motor 2021 and the second motor 2031 are also fixed on the upper surface of the support plate 201. The power shaft of the first motor 2021 is connected to the first threaded rod 202 through a set of rotating wheels, and the power shaft of the second motor 2031 is connected to the two second threaded rods 203 through another set of transmission wheels.

[0038] The first motor 2021 and the second motor 2031 are power sources for rotating the first threaded rod 202 and the second threaded rod 203 , which drive the first threaded rod 202 or the second threaded rod 203 to rotate, and finally realize the automatic opening and closing of the side plate 102 and the end plate 103 .

[0040] The specific working principle of the utility model is:

[0041] Automobile instrumentation is composed of various instruments and indicators, especially warning lights and alarms for drivers, which provide the driver with the required information on automobile operating parameters. The instrument can drive the base meter pointer through a stepper motor, or directly display graphics or text information using an LCD screen. At the same time, it also has an intelligent processing unit that can exchange information with other control units of the car. The function of automobile instrumentation is to obtain the required data and display it in an appropriate way; the instruments on different car dashboards are not the same, but the conventional instruments of general cars include speedometers, tachometers, oil pressure gauges, water temperature gauges, fuel gauges, charging gauges, etc. The automobile instrument panel bracket, as the name implies, is a support frame for placing the automobile instrument panel, and the automobile instrument bracket mold is a mold used to produce the instrument bracket, and the device is a molding mold for producing the automobile instrument panel bracket.

[0042] When using the device, it is necessary to turn on the power supply to ensure that the first motor 2021, the second motor 2031 and the hydraulic telescopic rod 209 are operating normally. First, the raw materials to be molded are added to the outer template 1 of the device (the outer template 1 is in a default buckled state). After the injection is completed, the hydraulic telescopic rod 209 is started to press the cover plate 104 into the inner side of the outer template 1, and wait for it to cool and form. After it is cooled, demoulding begins. First, the hydraulic telescopic rod 209 is started again to move the top plate 208 upward, and then the first motor 2021 is started. The first motor 2021 rotates through the transmission wheel group to drive the second A threaded rod 202 rotates, and then the two connecting blocks 204 threadedly connected on the first threaded rod 202 move toward the two ends of the first threaded rod 202, and then the end plate 103 is pulled to open outward through the connecting plate 205, and finally the end plate 103 is molded. The same is true for the side plate 102. The second motor 2031 rotates through another set of transmission wheel groups to drive the two second threaded rods 203 to rotate, and then drives the connecting blocks 204 on the second threaded rod 203 to move toward the two ends of the second threaded rod 203, and finally the end plate 103 is molded by pulling the connecting plate 205 connected to the connecting blocks 204.

[0043] After the side plate 102 and the end plate 103 are opened, the product is still connected to the bottom plate 101, and can be pried off by the pry bar 207. At this time, just hold the handle 2072 and apply downward pressure, and then the pry bar 207 will pry the pry plate 2071 under the action of the lever, and finally eject the mold. The advantage of this is that the convenience of demoulding is greatly increased.

[0044] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, as well as any modification, equivalent replacement and improvement made, are all protected by the present invention.
