In order to solve the problem that T-shaped rib flow marks are easy to generate when a container with an interlayer is molded in a spraying-free injection molding mode in the prior art, the application provides a container and a mold.

As shown in fig. 1 to 8, the container is a spray-free injection molded part, and includes an annular housing 10 and a partition 20. The bottom end of the annular housing 10 has an opening 11, the outer peripheral surface of the annular housing 10 is an exterior surface 12 and includes a front surface 121 and a back surface 122, and the opening 11 is located on the back surface 122. A partition 20 is provided within the annular housing 10, the partition 20 dividing the interior cavity of the annular housing 10 into at least two sub-chambers 13 independent of each other. Wherein the bottom end surface 14 of the annular shell 10 is provided with a gate molding area 15 corresponding to the gate 30, one gate molding area 15 is arranged, and one gate molding area 15 is positioned on the bottom end surface 14 and corresponds to the front surface 121; alternatively, the plurality of gate molding regions 15 are provided, and the plurality of gate molding regions 15 are disposed at intervals along the circumferential direction of the annular housing 10, and at least one gate molding region 15 is located on the bottom end surface 14 at a position corresponding to the front surface 121 and injection molding is performed prior to the remaining gate molding regions 15.

With the technical solution of the present embodiment, the container includes an annular housing 10 and a partition 20, the partition 20 is disposed in the annular housing 10 to divide the inner cavity of the annular housing 10 into at least two sub-chambers 13 independent of each other, and a bottom end surface 14 of the annular housing 10 has a gate molding area 15 for corresponding to the gate 30. When the number of the gate forming areas 15 is one, one gate forming area 15 is positioned on the bottom end surface 14 at a position corresponding to the front surface 121, namely, the front surface 121 of the annular shell 10 is subjected to injection molding before the other surfaces; when the number of the gate forming areas 15 is plural, at least one gate forming area 15 is located at a position on the bottom end face 14 corresponding to the front 121 and injection molding is performed before the rest of the gate forming areas 15, that is, glue is fed from the position of the front of the lower end of the container, so as to ensure that the appearance face 12 of the annular shell 10 is filled before the partition 20, thereby solving the problem that T-shaped rib flow marks are easily generated when the container with the partition is injection molded in a spraying-free injection molding mode in the prior art, and improving the appearance aesthetic degree of the container.

In this embodiment, after the gate 30 is removed, a cut mark is left, and the cut mark is located on the bottom end surface 14, so that the user is not easy to perceive, and the appearance quality of the container is improved.

Optionally, the outer peripheral surface of the annular housing 10 further includes a first side surface 16 and a second side surface 17, and the plurality of gate molding regions 15 includes a first gate molding region 151 and at least two second gate molding regions 152. The first gate molding region 151 is located on the bottom end surface 14 at a position corresponding to the front surface 121. At least one second gate molding zone 152 is located on the bottom end surface 14 at a position corresponding to the first side surface 16, and at least another second gate molding zone 152 is located on the bottom end surface 14 at a position corresponding to the second side surface 17. Wherein the first gate molding zone 151 is injection molded prior to the second gate molding zone 152. In this way, the first gate molding area 151 corresponds to the primary gate, the second gate molding area 152 corresponds to the secondary gate, and the primary gate is preferentially opened to ensure that the appearance surface 12 of the annular housing 10 is filled before the partition 20, so that the plurality of gate molding areas 15 are implemented to perform pouring according to time sequence, and further, the fusion of multiple strands of melt is avoided, so that the fusion line is eliminated, and the fusion line is ensured to be positioned on the back surface 122 of the container.

As shown in fig. 1 and 2, there are one first gate molding region 151, two second gate molding regions 152, and two second gate molding regions 152 disposed opposite to each other. In the process of filling and injection molding of the container, the main gate corresponding to the first gate forming area 151 is opened preferentially, the secondary gate is closed, and after the plastic melt passes through the second gate forming area 152, the secondary gate is opened again to form relay, so that the problem of merging at multiple positions caused by multi-gate filling is avoided.

Alternatively, the annular housing 10 includes a plurality of plates connected end to end, and the length of the first gate molding region 151 is 8mm or more; and/or, the width W1 of the first gate molding region 151 and the plate thickness W of the plate body of the annular housing 10 having the front face 121 satisfy: w1 is more than or equal to 0.5W and less than or equal to 0.8W. Thus, the longer the length of the first gate molding zone 151, the more advantageous the melt injection molding is to ensure the efficiency and quality of filling and pressure maintaining.

Alternatively, the length of the second gate molding zone 152 is greater than or equal to 6mm; and/or, the width W2 of the second gate molding region 152 and the plate thickness W' of the plate body of the annular housing 10 having the first side surface 16 or the second side surface 17 satisfy: w2 is more than or equal to 0.5W 'and less than or equal to 0.8W'. In this way, the longer the length of the second gate molding zone 152, the more advantageous the melt injection molding to ensure the efficiency and quality of filling and dwell.

As shown in fig. 8, the partition 20 includes a partition body 21 and a connection ring 22. The connection ring 22 is connected with the separator body 21 and is disposed around the separator body 21. Wherein, baffle body 21 passes through go-between 22 and the inner peripheral face of annular casing 10 is connected, and thickness D1 of go-between 22 is less than the thickness of baffle body 21, satisfies between thickness D1 and the thickness D of annular casing 10: d1 is more than or equal to 0.35D and less than or equal to 0.45D. Thus, the connecting ring 22 is a thinned area, and the cooling shrinkage in the thinned area is preferably completed to form a "partition" between the transverse material thickness and the longitudinal material thickness, and at this time, the cooling shrinkage of the transverse material thickness and the longitudinal material thickness are not affected, so that the problem of shrinkage of the appearance can be solved.

As shown in fig. 2 and 8, the container further includes a reinforcing rib 40. The reinforcing ribs 40 are provided between the partition plate 20 and the inner peripheral surface of the annular housing 10; the reinforcing ribs 40 are plural, and the plural reinforcing ribs 40 are arranged at intervals along the circumferential direction of the annular housing 10. Thus, the above arrangement improves the strength of the joint of the partition 20 and the annular housing 10, thereby prolonging the service life of the container.

Alternatively, the thickness D2 of the rib 40 and the thickness D of the annular housing 10 satisfy: d2 is more than or equal to 0.35D and less than or equal to 0.45D. Like this, above-mentioned setting makes the thickness d2 of strengthening rib 40 select more rationally, has not only reduced the processing cost of container, has also promoted the strengthening effect of strengthening rib 40.

Optionally, the annular housing 10 comprises a plurality of plates connected end to end, and in the direction from the top end face 18 to the bottom end face 14 of the annular housing 10, at least part of the plates of the annular housing 10 having the front face 121 have a plate thickness gradually increasing and a thickening value Δd satisfying between the thickness D' at this position: Δd is less than or equal to 0.3D'. Therefore, the appearance surface area corresponding to the position of the main gate is thickened locally and transited, so that the filling of the main gate is facilitated, the filling speed of the main gate is ensured to be always faster than that of the secondary gate, and the phenomenon that flow marks or subsurface flow marks of a converging included angle are caused by too fast filling of the secondary gate is avoided.

In this embodiment, the annular housing 10 is made of a spray-free material including a substrate and particles distributed within the substrate; wherein the base material is a thermoplastic polymer material; the particles are any one or more of metal particles, pearl powder and fibers. The spraying-free material contains the particles, so that the injection molding part has unique light and shadow effect and metallic luster after molding, and can achieve the appearance effect comparable to or better than spraying without secondary treatment.

Alternatively, the metal particles are aluminum or copper.

Alternatively, the fibers are nylon or natural fibers.

Alternatively, the weld line of the annular housing 10 is located on the back face 122; and/or, the appearance surface 12 is provided with a drawing line, and the extending direction of the drawing line is parallel to the flow direction of the melt. Thus, if the appearance surface 12 has flow marks, the direction of the flow marks is the same as the flow direction, and the extending direction of the drawing lines is parallel to the flow direction of the melt, so that the flow marks can be covered by the lines of the drawing lines, and the flow marks have a covering effect.

In the present embodiment, the gate 30 is a rectangular gate. The arrangement can ensure the low flow rate flow of the injection molding melt and the gate forming part is easy to remove.

Specifically, the injection molding process of the container is as follows:

the primary gate corresponding to the first gate forming region 151 is opened first, and at this time, the material flow starts to fill from the primary gate, and after the material flow passes through the gates of the other 2 second gate forming regions 152, the secondary gates corresponding to the two second gate forming regions 152 are opened again, so that the weld line is located on the back surface 122, and is not easily found. Meanwhile, the T-shaped rib flow marks can be avoided through the arrangement, so that the filling efficiency and the pressure maintaining efficiency and quality are guaranteed.

The application also provides a mould, the mould is provided with a cavity for forming the outer frame, the mould is further provided with a pouring gate 30, and the pouring gate 30 is communicated with the cavity.

From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

the container comprises an annular shell and a baffle plate, wherein the baffle plate is arranged in the annular shell to divide the inner cavity of the annular shell into at least two mutually independent subchambers, and the bottom end surface of the annular shell is provided with a pouring gate forming area corresponding to the pouring gate. When the number of the gate forming areas is one, one gate forming area is positioned on the bottom end surface and corresponds to the front surface, namely the front surface of the annular shell is subjected to injection molding before the other surfaces; when the pouring gate forming areas are multiple, at least one pouring gate forming area is positioned at the position corresponding to the front surface on the bottom end surface and is subjected to injection molding before other pouring gate forming areas, namely, glue is fed from the position of the front surface of the lower end of the container, so that the appearance surface of the annular shell is ensured to be filled before the partition plate, the problem that T-shaped rib flow marks are easy to generate when the container with the partition layer is subjected to injection molding in a spraying-free injection molding mode in the prior art is solved, and the appearance attractiveness of the container is improved.
