Description

Technical Field

[0001] The present utility model relates to the field of molds, and particularly to a mold for manufacturing models used in exhibition halls. Background Art

[0002] Many models exhibited in exhibition halls are produced by injection molding using injection molds. During these injection molding processes, since the injection plastic reaches the mold in a heated and molten state for shaping, a large amount of waste gas is released during the shaping process. If these waste gases are not effectively treated, they are likely to cause harm to the environment and the human body.

[0003] The prior art adsorbs waste gas by installing a waste gas adsorption and filtration structure on the mold, but there are two major problems:

[0004] 1. Since there is no corresponding dust filtration structure at the air inlet end, a large amount of dust in the air is sucked into the waste gas filtration structure, resulting in the situation where the filter element used to adsorb toxic and harmful substances in the waste gas is covered with dust, thereby reducing the adsorption effect.

[0005] 2. Usually, only one adsorption filter element for the waste gas filtration structure used on the mold is installed, resulting in the need for manual replacement at relatively frequent regular intervals, and the operation is cumbersome. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art problems, the purpose of the present utility model is to provide a mold for manufacturing models used in exhibition halls that can avoid the dust in the waste gas from clogging the filter element, resulting in a decrease in the adsorption effect of harmful substances in the waste gas, and can automatically switch the adsorption core at regular intervals, saving manpower.

[0007] In order to solve the prior art problems, the technical solution of the present utility model is as follows:

[0008] A mold for manufacturing models used in exhibition halls includes a moving mold and a stationary mold arranged opposite to each other. An exhaust gas adsorption assembly for adsorbing the exhaust gas generated by injection molding is fixed on the outer wall of the stationary mold. A dust-proof filter net is fixed at the air inlet end of the exhaust gas adsorption assembly. An automatic cleaning assembly for automatically cleaning the dust-proof filter net is fixed on the outer wall of the moving mold.

[0009] Preferably, the exhaust gas adsorption assembly includes a gas collecting hood fixed on the bottom surface of the stationary mold. The dust-proof filter net is fixed at the upper end of the inner wall of the gas collecting hood. A carrier plate is fixed at the bottom of the gas collecting hood. An air pump is fixed at the bottom of the carrier plate. The air inlet end of the air pump is connected to the air outlet end of the gas collecting hood through an air delivery pipe. A plurality of adsorption sleeves are arranged side by side at the bottom of the carrier plate through a moving assembly. The moving assembly is used to switch different adsorption sleeves to be connected to the air outlet end of the air pump.

[0010] Preferably, an adsorption core is inserted inside the adsorption sleeve. One end of the adsorption sleeve away from the air pump is threadedly connected with a threaded cover through an external thread, and the threaded cover is hollow.

[0011] Preferably, the moving component includes a mounting frame slidably installed at the bottom of the carrier plate through a slide rail. A plurality of the adsorption sleeves are fixedly arranged on the mounting frame at equal intervals, and one end of the adsorption sleeve close to the air pump is fixed to the outer wall of the mounting frame. A plurality of ventilation holes are equally spaced at one end of the mounting frame close to the air pump, and each ventilation hole is communicated with the inner wall of an adsorption sleeve. The air outlet end of the air pump abuts against the outer wall of the mounting frame, and a linear motor is fixed in the middle of the bottom surface of the carrier plate. The moving end of the linear motor is fixed to the outer wall of the mounting frame.

[0012] Preferably, an air outlet cover is fixed to the air outlet end of the air pump. The air outlet cover abuts tightly against the outer wall of the mounting frame, and a sealing gasket is fixed to one side of the air outlet cover close to the mounting frame.

[0013] Preferably, the automatic cleaning component includes a brush strip fixed to the bottom of the moving mold, and the brush strip cooperates with the dust-proof filter net.

[0014] Compared with the related art, the utility model has the following beneficial effects:

[0015] 1. By arranging a gas collecting hood and a dust-proof filter net at the air inlet end of the air pump, the waste gas entering the inner side of the waste gas adsorption component can be filtered for dust, reducing the probability of dust clogging the adsorption core and ensuring that the adsorption core always has good gas permeability;

[0016] 2. By fixing a brush strip at the bottom of the moving mold, the automatic cleaning work of the dust-proof filter net can be completed by using the power of the opening and closing of the moving mold and the static mold during the injection molding process, so that the dust-proof filter net does not need to be cleaned manually regularly, greatly saving manpower. At the same time, there is no need to add power equipment for cleaning work, saving the production manufacturing and operation maintenance costs of the equipment;

[0017] 3. By arranging a plurality of adsorption sleeves and setting a moving component to automatically switch different adsorption sleeves to connect with the air pump, workers can directly replace multiple adsorption cores at one time, and then the equipment can automatically switch the adsorption cores, without the need for workers to repeatedly and frequently switch the adsorption cores, which is more convenient to use.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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.

[0027] Embodiment 1, please refer to Figure 1 、 Figures 3 to 7 , this embodiment provides a mold for manufacturing models for exhibition halls. A mold for manufacturing models for exhibition halls includes a moving mold 1 and a stationary mold 2 arranged opposite to each other. A waste gas adsorption component 3 for adsorbing waste gas generated during injection molding is fixed on the outer wall of the stationary mold 2. A dust-proof filter screen 4 is fixed at the intake end of the waste gas adsorption component 3. An automatic cleaning component 5 for automatically cleaning the dust-proof filter screen 4 is fixed on the outer wall of the moving mold 1;

[0028] Setting the dust-proof filter screen 4 can filter dust from the gas entering the waste gas adsorption component 3, avoiding the situation where the waste gas adsorption component 3 is blocked by dust, and ensuring the effect of the waste gas adsorption component 3 in adsorbing harmful substances in the waste gas;

[0029] The automatic cleaning component 5 can utilize the power of the opening and closing of the moving mold 1 and the stationary mold 2 during injection molding of the model to complete the cleaning work of the dust-proof filter screen 4, eliminating the need for manual cleaning, greatly saving manpower, and at the same time saving the equipment manufacturing and maintenance costs;

[0030] The exhaust gas adsorption assembly 3 includes a gas collecting hood 31 fixed to the bottom surface of the static mold 2. A dust-proof filter screen 4 is fixed to the upper end of the inner wall of the gas collecting hood 31. A carrier plate 32 is fixed to the bottom of the gas collecting hood 31. A gas pump 33 is fixed to the bottom of the carrier plate 32. The intake end of the gas pump 33 is connected to the outlet end of the gas collecting hood 31 through an air delivery pipe 34. A plurality of adsorption sleeves 35 are arranged side by side at the bottom of the carrier plate 32 through a moving assembly 36. The moving assembly 36 is used to switch different adsorption sleeves 35 to be connected to the outlet end of the gas pump 33;

[0031] An adsorption core 351 is inserted into the inner side of the adsorption sleeve 35. One end of the adsorption sleeve 35 away from the gas pump 33 is threadedly connected with a threaded cover 352 through an external thread. The threaded cover 352 is provided in a hollow manner;

[0032] When one end of an adsorption sleeve 35 is connected to the outlet end of the gas pump 33, by operating the gas pump 33, the exhaust gas overflowing after the moving mold 1 and the static mold 2 are opened is sucked. The exhaust gas enters the gas collecting hood 31 through the dust-proof filter screen 4, and then enters the adsorption sleeve 35 through the gas pump 33. The harmful substances in the exhaust gas are filtered by the adsorption core 351 when entering the adsorption sleeve 35 from one end of the adsorption sleeve 35, and then the treated air is discharged from the threaded cover 352, completing the adsorption work of the harmful substances in the exhaust gas;

[0033] The moving assembly 36 includes a mounting frame 361 slidably mounted on the bottom of the carrier plate 32 through a slide rail. A plurality of adsorption sleeves 35 are fixed to the mounting frame 361 at equal intervals, and one end of the adsorption sleeve 35 close to the gas pump 33 is fixed to the outer wall of the mounting frame 361. A plurality of ventilation holes 362 are equally spaced at one end of the mounting frame 361 close to the gas pump 33, and each ventilation hole 362 is communicated with the inner wall of an adsorption sleeve 35. The outlet end of the gas pump 33 abuts against the outer wall of the mounting frame 361. A linear motor 363 is fixed to the middle of the bottom surface of the carrier plate 32, and the moving end of the linear motor 363 is fixed to the outer wall of the mounting frame 361;

[0034] When automatically switching the adsorption sleeve 35, by driving the linear motor 363 to work to drive the carrier plate 32 to move, the adsorption sleeve 35 can be driven to move, so that the ineffective adsorption sleeve 35 moves to one side, and the effective adsorption sleeve 35 moves to be directly opposite the outlet end of the gas pump 33. After the adsorption sleeve 35 is directly opposite the outlet end of the gas pump 33, the adsorption sleeve 35 is connected to the outlet end of the gas pump 33 through the ventilation hole 362;

[0035] An outlet hood cover 6 is fixed to the outlet end of the gas pump 33. The outlet hood cover 6 abuts tightly against the outer wall of the mounting frame 361. A sealing gasket 7 is fixed to one side of the outlet hood cover 6 close to the mounting frame 361;

[0036] When moving the position of the mobile adsorption sleeve 35 and the mounting frame 361 slides, the air outlet cover always presses tightly against the sealing gasket 7 and presses on the outer wall of the mounting frame 361 until the adsorption sleeve 35 moves into place. When a ventilation hole 362 is aligned with the air outlet end of the air pump 33, the sealing gasket 7 seals around the outer circumference of the ventilation hole 362 to ensure that the exhaust gas will not overflow from the contact part between the air outlet end of the air pump 33 and the mounting frame 361 after passing through the air pump 33.

[0037] Embodiment 2. Please refer to Figure 2 , this embodiment provides a further technical solution based on Embodiment 1. The automatic cleaning component 5 includes a brush strip 51 fixed to the bottom of the moving die 1. The brush strip 51 cooperates with the dust-proof filter net 4. During the process of mold opening and closing, the movement of the moving die 1 drives the brush strip 51 to move. The brush strip 51 automatically brushes the dust-proof filter net 4 when passing through the dust-proof filter net 4 to complete the cleaning work of the dust-proof filter net 4 without manual cleaning.
