Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a precise high-temperature controlled mold heater. Background Art

[0002] Precision high temperature controlled mold heater is a device used to heat the mold, usually used in plastic injection molding, die casting, hot pressing and other processes. Its main function is to provide precise temperature control and uniform heating in the mold. The device contains one or more heating elements, usually electric heating rods or heating coils, which generate heat energy and transfer it to the mold.

[0003] However, the heat of the heating element is conducted heat. The area of ​​the mold surface close to the heating element tends to reach the required working temperature faster, while the area far away from the heating element is slower. This will cause uneven temperature distribution in the mold cavity, causing part of the molten material to be affected during the cooling process. For this reason, we propose a precision high-temperature controlled mold heater to solve the existing problem. Utility Model Content

[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] like Figure 1-Figure 4 As shown, the utility model provides a precision high temperature controlled mold heater, comprising a bottom plate 100, a mold structure 200, a sleeve structure 300, a rotating structure 400 and a mold opening structure 500.

[0055] A mold structure 200 is disposed on the upper end of the bottom plate 100. The mold structure 200 includes:

[0056] A fixed mold 202, located above the bottom plate 100;

[0057] The movable mold 205 is located above the movable mold 205;

[0058] The fixed sleeve 201 is sleeved on the outer side of the fixed mold 202;

[0059] The movable sleeve 204 is sleeved on the outer side of the movable mold 205;

[0060] A heating component 203 is provided to fill between the fixed mold 202 and the fixed sleeve 201 and between the fixed sleeve 201 and the movable sleeve 204;

[0061] A half shaft 207 is located on the outer wall of the fixed sleeve 201 and the movable sleeve 204 on the same side;

[0062] The one-way valve port 206 penetrates the interior of the installation and movable mold 205;

[0063] The sleeve structure 300 comprises:

[0064] Motor 1 301, located at one side of the upper end of the bottom plate 100;

[0065] Screw 304, fixed to the output shaft end of motor 1 301;

[0066] The mounting plate 305 is located on both sides of the upper end of the bottom plate 100;

[0067] Screw hole 307, opened inside the mounting plate 305;

[0068] A symmetrically distributed bracket 209 is provided on the upper end of the bottom plate 100, a semicircular conductive ring 208 is provided on the upper end of the bracket 209, a conductive sleeve is provided on the outer wall of the semi-axis 207, and the guide sleeve is electrically connected to the heating component 203, and the conductive sleeve is connected to the conductive ring 208 and the rotating sleeve 204.

[0069] The screw rod 304 is rotatably inserted into the screw hole 307 , and the threads on the outer wall of the screw rod 304 are relatively distributed.

[0070] A sliding seat 303 is disposed at the upper end of the bottom plate 100 , and a slider 302 is disposed at the lower end of the mounting plate 305 . The slider 302 is slidably mounted inside the sliding seat 303 .

[0071] The one-way valve port 206 includes:

[0072] The installation tube passes through the movable sleeve 204 and the movable mold 205;

[0073] A valve seat, located inside the mounting tube;

[0074] The valve block is elastically mounted to the valve seat through a spring;

[0075] A valve ring, engaged with the open end of the valve block;

[0076] Among them, the valve ring, valve block, spring and valve seat are distributed in sequence from top to bottom.

[0077] Based on the implementation steps of Example 1: After the fixed mold 202 and the movable mold 205 are closed, the motor 1 301 drives the screw 304 to rotate, and the mounting plate 305 slides horizontally inside the slide seat 303 through the slider 302. The mounting plate 305 is guided by the sliding guide at the upper end of the bottom plate 100, and the screw 304 pushes the screw hole 307 to slide on the outer wall of the screw 304. Because the threads on the outer wall of the screw 304 are relatively distributed, the mounting plate 305 moves relatively, driving the bearing sleeve to be connected to the closed outer wall of the half shaft 1 207 and the half shaft 2 402, the fixed mold 202 and the movable mold 205 are closed, and the sleeve 306 supports the half shaft 1 207 and the eight shaft 2 for rotation;

[0078] The molten material delivery pipe of the injection device is inserted into the one-way valve port 206. When the valve block is opened, the liquid material is injected into the mold cavities inside the fixed mold 202 and the movable mold 205. The elastic part inside the one-way valve port 206 automatically resets after losing the extrusion. When the one-way valve port 206 is closed, the one-way valve port 206 is also used for injection of other different molds. The injection equipment can be separated from the movable mold 205, which is very practical in places where molds need to be replaced frequently.

[0079] like Figure 1-Figure 4 As shown, the precision high temperature controlled mold heater proposed by the utility model is compared with the first embodiment, and this embodiment also includes:

[0080] The rotating structure 400 includes:

[0081] Motor 2 404 is located on one side of the upper end of the screw 304.

[0082] A second half shaft 402 is located on the outer wall of the fixed sleeve 201 and the movable sleeve 204 on the same side;

[0083] The half gear 401 is sleeved on the outer walls of the fixed sleeve 201 and the movable sleeve 204;

[0084] The driving wheel 403 is located on the outer wall of the output end of the second motor 404 .

[0085] The driving wheel 403 meshes with the half gear 401 on one side of the fixed sleeve 201. After the driving wheel 403 meshes with the half gear 401, the driving wheel 403 pushes the half gear 401 to rotate.

[0086] The mold opening structure 500 includes:

[0087] The hydraulic rods 501 are symmetrically distributed on both sides above the movable mold;

[0088] The second bracket 502 is sleeved on the outer wall of the hydraulic rod 501, and the lower end is connected to the bottom plate 100;

[0089] The electromagnet 503 is located at the lower end of the hydraulic rod 501;

[0090] Magnetic attractors 504 are located on both sides of the upper end of the movable mold;

[0091] The electromagnet 503 corresponds to the magnetic magnet 504 .

[0092] After the molten material is injected, the motor 2 404 drives the driving wheel 403 to rotate, and the driving wheel 403 pushes the half gear 401 to form a full-circle gear after closing, driving the movable mold 205 and the fixed mold 202 to rotate. The internal molten material is mixed during the rotation process. At the same time, the conductive sleeve contacts the conductive ring 208 to provide power supply for the conductive ring 208 during rotation. The heating component 203 heats the movable mold 205 and the fixed mold 202. The internal molten material is heated during the mixing process and is heated evenly.

[0093] Uneven heating speed will cause some molten materials or products to shrink or expand inconsistently during the cooling process. The temperature difference caused by uneven heating speed will cause some molten materials or products to form internal stress during the cooling process. These internal stresses may cause defects such as cracks, distortion or tearing, and reduce the structural strength and durability of the product. Due to the uneven heating speed, the cooling speed of some molten materials or products will also be different, which may lead to uneven surface quality, such as melt marks, scars, bubbles, warping, color differences, etc. Cover molds are suitable for the use of large molds, so that large molds are heated evenly and product quality is improved;

[0094] After heating, wait for the mold to cool down. After cooling, the sleeve 306 moves out of the outer wall of the half-shaft 1 207 and the half-shaft 2 402, and the hydraulic rod 501 drives the electromagnet 503 to move longitudinally. When it contacts the magnetic iron 504, the electromagnet 503 is energized to generate magnetic attraction to attract the magnetic iron 504, thereby driving the movable mold 205 to move longitudinally, and the cooled mold base is taken out.

Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
