Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a coffee powder box production molding device. Background Art

[0002] Injection molds are indispensable equipment for manufacturing plastic products. They not only provide precise size and structure for products, but also ensure the integrity of products. Injection molding technology is an efficient production method, especially suitable for mass production of parts with complex shapes. In this process, molten plastic is injected into the mold cavity under the high pressure of the injection molding machine, and then solidified by cooling to form the final product.

[0003] However, the existing injection mold design is inconvenient to demold the mold, which not only affects the efficiency of mold replacement, but also wastes time in the process of separating the product from the mold after molding, thereby reducing the overall production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a coffee powder box production molding device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A coffee powder box production molding device comprises a base and a side plate, the side plates are symmetrically fixedly connected to two ends of the base; a first cylinder and a second cylinder are fixedly provided on opposite sides of the two side plates, a first pair of molds are fixedly connected to the movable end of the first cylinder, and a second pair of molds are fixedly connected to the movable end of the second cylinder; a sliding rod is fixedly provided between the two side plates, and the first pair of molds and the second pair of molds are slidably connected to the sliding rod; a demolding component is fixedly provided in the first pair of molds, and the demolding component is used to remove the mold on the first pair of molds; a piston cylinder is fixedly provided at the upper end of the first pair of molds, a leakage port is opened on one side of the bottom end of the piston cylinder, a piston is fixedly provided in the piston cylinder, a piston rod is fixedly provided on the piston, a push-pull plate is fixedly provided at one end of the piston rod, and a slot is fixedly provided on the second pair of molds; a connecting pipe is provided at the bottom end of the piston, and the connecting pipe is communicated with the demolding component; an injection device is fixedly provided on the base, and the injection device is communicated with the second mold; the injection device is used to inject raw materials into the second mold.

[0007] By starting the first cylinder in the positive direction, the first cylinder drives the first pair of dies to move and fit closely with the second pair of dies. The injection device contains raw materials, which are injected into the second pair of dies through the injection device. After waiting for a period of time, when the raw materials are cooled, the first cylinder is started in the reverse direction to drive the first pair of dies to move, so that the first pair of dies and the second pair of dies are separated. The product with good plasticity will be bonded to the first pair of dies. Then the first cylinder is started in the positive direction again, and the first cylinder drives the first pair of dies to return to their original position. The push-pull plate is clamped on the card slot, so that the piston moves in the opposite direction of the cylinder movement, and the gas is pressed into the connecting pipe to drive the demoulding component to protrude, thereby separating the product from the first pair of dies.

[0008] A further improvement of the technical solution of the utility model lies in that: the demoulding component includes an trachea body, the interior of the trachea body is hollow, an opening is provided on the trachea body, a top block is slidably provided in the opening, a spring is provided inside the trachea body, and the spring is fixedly connected to the trachea body and the top block; a through hole is provided at the top end of the trachea body, and the through hole is communicated with the connecting pipe; a demoulding opening is provided at a position on the side of the first pair of molds that matches the position of the opening.

[0009] By adopting the above technical solution, when the piston presses the gas in the piston cylinder, the gas enters the trachea body through the connecting pipe, causing the air pressure in the trachea to increase. When the pressure of the gas on the top block is greater than the elastic force of the spring, the top block will be forced to bulge out, and the bulging of the top block drives the product to separate from the first pair of molds; the gas in the piston cylinder will escape through the leak, slowly balancing the air pressure inside the piston cylinder, so that the top block is retracted to be flush with the side, preventing the top block from bulging out and making the product surface uneven, affecting product quality.

[0010] A further improvement of the technical solution of the utility model is that openings are arranged on the outer side of the trachea.

[0011] By adopting the above technical solution, openings are arranged on the outer side of the trachea body, so that the top block can be demoulded not only on the side but also on the end face, thereby improving the demoulding effect.

The feed pipe is arranged perpendicular to the injection device.

[0013] The above technical solution is adopted. In this embodiment, the feed pipe is arranged perpendicular to the injection device. When the raw material input is stopped, the raw material can flow back more quickly through the injection pipe under the action of gravity.

[0014] A further improvement of the technical solution of the utility model is that: preferably, a material receiving trough is fixedly provided on the slide rod.

[0015] The above technical solution is adopted, in which a material receiving chute is provided to ensure that the product can be safely and stably received after demoulding, thereby preventing the product from falling and being damaged due to improper reception.

[0016] A further improvement of the technical solution of the utility model is that a flexible rubber is fixedly provided on the end surface of the top block.

[0017] The above technical solution is adopted, in which a flexible rubber is fixedly provided on the end surface of the ejector block to ensure that the ejector block does not cause damage to the surface of the product when ejecting the product.

[0018] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0019] 1. The utility model provides a coffee powder box production molding device, which starts the first cylinder in a positive direction, drives the first pair of dies to move and fit closely with the second pair of dies, and the raw materials are contained in the injection device, and the raw materials are injected into the second pair of dies through the injection device, and wait for a period of time, until the raw materials are cooled, and then starts the first cylinder in a reverse direction to drive the first pair of dies to move, so that the first pair of dies and the second pair of dies are separated, and the product with good plasticity will be adhered to the first pair of dies, and then starts the first cylinder in a positive direction again, and the first cylinder will drive the first pair of dies to return, and the push-pull plate is clamped on the card slot, so that the piston moves in the opposite direction to the cylinder movement, and the piston squeezes the gas in the piston cylinder, and the gas enters through the connecting pipe, and the gas drives the demoulding component to bulge out, so that the product is separated from the first pair of dies.
