the preliminary mold cavity A11 of the runner plate A1 corresponds to the molding cavity C11 of the lower molding die C1 to form a molding space, and in the machine operation working position, the glue is injected into the preliminary mold cavity A11 of the first runner plate A1 and the molding cavity C11 of the lower molding die C1; the runner plate A1 is provided with an independent cooling channel A4 and a first heating plate A5, the external pipe of the cooling channel A4 is connected with a cooling medium (such as liquid or gas) and can circulate in the cooling channel A4, and the first heating plate A5 provides a mechanism for heating and melting granular rubber materials into an ejectable colloidal material (about 70-100 ℃); however, since the sizing material is inevitably excessively thermally aged in a state where the first heating plate a5 is continuously heated, the flow path plate a1 is maintained at a proper temperature without being excessively heated by the cooling path a 4.
The second module B is provided with a water cooling type steel plate heat insulation cooling plate B1 (drilled with holes required by cooling circulating water, screw holes and locking screws for fixing a slide rail and the whole module mechanism), a honeycomb or net-shaped steel plate second heat insulation plate B2 (one side of the steel plate is processed into honeycomb or net-shaped grooves to form a second line heat insulation plate), a first heat insulation plate B3 made of asbestos or plastic steel (used as a first line heat insulation plate contacted with a heating plate to block most part of temperature), a second heating plate B4 (the heat source for providing high-temperature vulcanization required by a finished product upper die reaches more than 150 ℃), which is positioned in the middle of the whole module mechanism, a rail B6 made of steel provides the action of the forward and backward displacement of the second module B in operation, a machine for pushing the displacement is carried out by an oil pressure push-pull mechanism B7, the second module B is provided with an upper forming die B5, the upper forming die B5 is provided with a plurality of die grooves B51, the cavity B51 corresponds to the cavity C11 of the lower molding die C1.

The operation of the thermoforming glue material injection machine of the present invention is shown in fig. 2 to fig. 3, and detailed in sequence as follows:
a. firstly, a separate runner plate A1 is locked on the top of the oil pressure hanging rod fixed on the machine tool, and is positioned below a first heating plate A5 and tightly combined; the second module B is positioned at the rear part of the middle of the machine tool, and the third module C is positioned below the machine tool.
b. After the third die set C is lifted by the lower oil press and combined with the split runner plate A1, the hot forming glue injection machine injects glue to the runner plate A1 through the injection nozzle through the injection opening A2, the glue is introduced into the forming space of the preliminary die groove A11 and the forming groove C11 through the runner groove A3 of the runner plate A1, and the glue injection is completed until the die filling is completed.
c. The lower hydraulic press descends to position the third die set C, and the glue in the forming space is kept on the forming groove C11 in a gel form.
d. The second module B slides forwards from the back of the machine to the middle of the first module A and the third module C to perform positioning action through a track B6 and an oil pressure push-pull mechanism B7.
e. The lower hydraulic press again ascends to lift the third module C until the lower forming die C1 and the upper forming die B5 are tightly combined, and the second heating plate B4 starts to heat to make the glue in the die groove B51 and the forming groove C11 reach the vulcanization temperature (heated to more than 150 ℃) until the finished product is cured.
f. After the product is cured, the lower oil press descends to separate the third module C from the second module B and descend to a fixed position, and the product in the molding groove C11 is taken out.
g. The module mechanism locks the second module B and slides to the rear of the machine table through the rail B6 and the hydraulic push-pull mechanism B7.
h. Repeating the actions from 'b' to 'g' again, thus being capable of circularly producing without pulling out the sizing material of the runner groove A3 in the separated runner plate A1, further saving the sizing material and manpower and leading the manufacturing process to be quicker.
The upper heating plate of the general thermal forming glue material injection machine only provides the electric heating pipe required by the heat source of the mold, and the time can be more than one hundred seconds when the action of injecting the glue material is performed, so that the separated runner plate A1 contacts with the lower forming mold C1 for a long time, and the temperature of the separated runner plate A1 is too high to be controlled, therefore, the first heating plate A5 of the utility model is provided with the cooling channel A4 for circulating holes required by cooling media (water or cooling liquid), namely, the temperature of the separated runner plate A1 and the glue material in the injection opening A2 is at the optimal working temperature.
In summary, since the flow channel plate a1 is disposed in the first module a, the flow channel A3 in the flow channel plate a1 can be maintained at a proper temperature (70-100 degrees celsius), so that the glue in the flow channel A3 does not gel. Since the material in the sprue a2 is not gelled, virtually no or only a small amount of waste-causing cured compound adheres to the molding. In addition, in this way, a blockage of the injection opening a2 can likewise be avoided, so that an injection of additional glue is ensured, which is advantageous, and furthermore, since it is no longer necessary to cut the runner channel A3 into the forming tool, so that it becomes an element of another part of the forming tool.
The second module B is provided with a water cooling type steel plate heat insulation cooling plate B1 which can be used as a second cooling device and can avoid the over-high temperature of the first module A when a heat source dissipates heat; the first insulation board B2 of honeycomb or net-like steel plate and the second insulation board B3 made of asbestos or plastic steel are used as the first line and the second line of the contact surface with the second heating board B4 to insulate the heat lines to prevent the first module A from overheating due to most of the temperature rise.
