[0023] Reference Figure 1-7 As shown, the gas meter outlet pipe injection mold of the utility model comprises an upper template 1, a lower template 2, and an outlet pipe mold core assembly 3 arranged between the upper template 1 and the lower template 2. The lower template 2 is connected to a mold bottom plate 5 on both sides through a side plate 4. The outlet pipe mold core assembly 3 is composed of a core bottom plate 6 fixed on the lower template 2, a core body 7 movably arranged on the core bottom plate 6, and a core plug rod 8 inserted into the core body 7. The top of the core plug rod 8 is fixed to the upper template 1, and the core body 7 is composed of a left core body 9 and a right core body 10. Slide blocks 11 connected to the left core body 9 and the right core body 10 are respectively provided at both ends of the lower template 2. At least one push-pull inclined rod 12 is provided in the slide block 11, and the upper end of the push-pull inclined rod 12 is fixed to the upper template 1. A gas meter outlet pipe cavity is formed between the left core body 9, the right core body 10, the core bottom plate 6 and the core plug rod 8. An injection molding flow channel connected with the gas meter outlet pipe cavity is provided on the upper mold plate 1 .

[0024] Preferably, the outer side of the slider 11 is provided with an inclined surface 13, and a wear-resistant plate 14 is fixed on the inclined surface 13, and the wear-resistant plate 14 is made of a more wear-resistant tungsten alloy. The slider 11 can be more stably positioned with the upper mold plate 1 through the inclined surface 13. Since the upper mold plate 1 often collides with the slider 11 during the mold closing process, the precision of the slider 11 will be reduced due to the wear on the surface. The wear-resistant plate 14 can improve the durability and facilitate replacement.

[0025] Preferably, two sides of the lower template 2 are provided with slide grooves 15, and the bottom of the slider 11 is provided with a slide rail 16 that slidably cooperates with the slide grooves 15, so that the slider 11 slides more smoothly.

[0026] Preferably, corresponding T-slots 27 are provided between the slider 11 and the left mold core body 9 and the right mold core body 10, and the T-slots 27 are connected by H-shaped connecting rods 26 to facilitate the connection between the slider 11 and the left mold core body 9 and the right mold core body 10.

[0027] Preferably, a group of demoulding ejector pins 17 are provided on the core bottom plate 6, and the bottom of the demoulding ejector pins 17 is connected to the demoulding plate 18, and the mold bottom plate 5 is provided with a demoulding hole 19 connected to the demoulding plate 18. When the upper mold plate is opened, the mold plate 18 can be pushed up by the ejector rod of the ejection mechanism through the demoulding hole 19, thereby driving the demoulding ejector pins 17 to push up, and then the gas meter outlet pipe is ejected from the core bottom plate 6, so as to facilitate the removal of the gas meter outlet pipe.

[0028] Preferably, the demoulding plate 18 is fixed with a demoulding ejector pin 20, and the upper end of the demoulding ejector pin 20 passes through the lower template 2 and abuts against the upper template 1. When the ejection mechanism pushes up the template 18, the upper template 1 can be pushed up synchronously by the demoulding ejector pin 20 to achieve synchronization of mold opening and demoulding, thereby simplifying the mechanism and improving efficiency.

[0029] Preferably, a buffer spring 21 is sleeved on the demoulding ejector rod 20 to provide a better buffering and resetting effect on the demoulding plate 18 .

[0030] Preferably, a guide column 22 is fixed on the lower template 2, and a guide sleeve 23 is provided on the upper template 1 to cooperate with the guide column 22, so that the opening and closing of the upper template 1 and the lower template 2 are more accurate.

[0031] Preferably, the core bottom plate 6 is provided with cooling holes 24, and a cooling pipe is connected to the cooling hole 24, and then a coolant is injected to accelerate the cooling speed of the work, thereby improving efficiency.

[0032] Preferably, the outlet pipe mold core assembly 3 is provided with two mold cavities 25, and the push-pull inclined rods 12 are two, so as to realize the one-out-two production of workpieces and improve production efficiency.
