[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] Refer to the attached Figure 1-2 , a forced demolding device for product sticking mold in hot plate welding. The demolding device is installed on the hot die bottom plate, and its top passes through the 5 hot die tooling plates. The 5 hot die tooling plates are fixedly installed on the hot die bottom plate through fixing columns. The demolding device includes 1 ceramic heat insulation sleeve, 2 spring travel pins, 3 travel pin sleeves, and 4 travel pin sleeve adjustment blocks. The 5 hot die tooling plates are provided with mounting holes, and the 2 spring travel pins are slidably installed in the mounting holes. The top end of the 2 spring travel pins is fixedly installed with the 1 ceramic heat insulation sleeve, and the bottom end is fixedly installed with the 3 travel pin sleeves;

[0020] There are screw through holes and counterbores inside the 1 ceramic heat insulation sleeve. A threaded hole is made at the top end of the 2 spring travel pins, and the 1 ceramic heat insulation sleeve is fixed to the top end of the 2 spring travel pins through screws.

[0021] Fix the 3-stroke pin sleeve and the 2-spring stroke pin through their own screw hole structure and then put them into the middle hole of the 4-stroke pin sleeve adjustment block. Make a 1mm gap in the middle of the 4-stroke pin sleeve adjustment block, and tighten the screws through the view orientation screw holes to adjust the upper and lower heights of the hot mold forced demoulding device;

[0022] Among them, holes need to be opened on the 5 hot mold tooling plate and the hot mold bottom plate to avoid interference with the hot mold forced demolding device.

[0023] The utility model discloses a hot mold forced demoulding device which is installed in the middle of the hot mold plate, and 1 to 2 pieces are evenly distributed according to the size of the welding product. The upper and lower heights of the forced demoulding device are adjusted by a 4-stroke pin sleeve adjustment block, so that the product can be forcedly demoulded after heating is completed.

[0024] 1. The ceramic heat-insulating sleeve and 2. The spring travel pin are fixed by screws; 3. The travel pin sleeve and 2. The spring travel pin are fixed by their own screw hole structure and then put into the middle hole of the 4. The travel pin sleeve adjustment block is fixed with the middle locking screw, and then the 4. The travel pin sleeve adjustment block is fixed as a whole on the hot mold bottom plate; the hot mold forced demoulding device is placed on the 5. The hot mold tooling plate is opened with a hole to avoid interference with the hot mold forced demoulding device;

[0025] The utility model has a simple installation method. The 2 spring stroke pins are fixed in the 4 stroke pin sleeve adjustment block through the 3 stroke pin sleeve through their own threaded structure. The subsequent loosening and tightening of the 4 stroke pin sleeve adjustment block forms an overall adjustment of the forced demoulding device.

[0026] Small product size: Limited by the size of the mold tooling and the internal structure of the plastic welding product, the smaller the contact surface between the forced demoulding device and the inner wall of the product, the better. Therefore, the size of the 2 spring travel pins and 1 ceramic insulation sleeve cannot be too large. It is sufficient to use a travel pin with an ejection load greater than 5N.

[0027] Adjustment margin: In order for the forced demoulding device to be suitable for most hot mold tooling, the forced demoulding device must have a certain adjustment margin. The 3-stroke pin sleeve is adjusted by the 4-stroke pin sleeve adjustment block screw to allow the forced demoulding device to have an upper and lower adjustment margin (multiple stroke adjustments can be set by changing the size of the 3-stroke pin sleeve);

[0028] The top sleeve needs to be made of high temperature resistant material to ensure that there is no sticking between the ceramic insulation sleeve and the product during contact, so that the product can successfully leave the hot mold heating area.

[0029] The 4-stroke pin sleeve adjusting block is fixedly installed on the hot mold bottom plate, and the 3-stroke pin sleeve is fixedly installed on the 4-stroke pin sleeve adjusting block.

[0030] The 2-spring travel pin adopts a telescopic structure, and the 1-ceramic heat insulation sleeve extends out of the mounting hole under the action of the 2-spring travel pin.

[0031] The bottom end of the 2-spring travel pin is provided with a thread, and the 3-travel pin sleeve is sleeved on the 2-spring travel pin through the thread.

[0032] The 6-heating tubes and 7-thermocouples are respectively installed inside the 5-hot die tooling plate.

[0033] The 4-travel pin sleeve adjusting block fixes the 2-spring travel pin by clamping the 3-travel pin sleeve, and is locked by a locking screw.

[0034] By loosening and tightening the locking screw in the middle of the view of the 4-travel pin sleeve adjusting block, the up and down height of the 2-spring travel pin is adjusted until it meets the requirements of the self-travel of the 2-spring travel pin;

[0035] The working process of the present utility model: When the equipment heating process starts, the product is adsorbed on the upper and lower cold dies and moves towards the hot die. After the upper and lower cold dies move to the set position, the welding ribs of the product start to be heated at high temperature. The plastic welded product contacts and is stressed by the 1-ceramic heat insulation sleeve, and the stress is transmitted to the 2-spring travel pin at the hot die part and is pressed and stressed;

[0036] After the heating is completed, the cold die tooling and the hot die device are separated up and down. The stress on the 2-spring travel pin is cancelled, and the 1-ceramic heat insulation sleeve is acted on by the elastic force of the 2-spring travel pin and ejects the plastic welded product; thus, the product welding program ends.
